[Preface]
Dry goods, intuitively understood, refer to condiments and foods with water removed by air-drying and air-drying, such as dried peppers, fungus, laver and mushrooms with water removed. Dry goods are extended to all walks of life, which means that the content shared is practical and does not contain water blowing components, indicating that this knowledge, methods and skills are more important and practical.
After many posts of Lao Su riding the motherland freely with a small electric car were published on 8264. com, many netizens expressed concern about this alternative way of riding and put forward some practical problems in traveling by electric car. Do you want to write a special post to talk about your personal experience? My heart has always been tangled. Lao Su is just an ordinary electric bicycle rider. Although he has some practical experience, he is just a little white in the technical theory of electric vehicles, and it is difficult to answer accurately and scientifically. However, recalling a lot of riding information from website platforms and netizens in the past ten years, I have benefited a lot and should be grateful for your help. Although my level and ability are limited, I can also be a paving stone for electric car travel, so that the latecomers can feel more at ease. I’d like to open my mind and feel at ease. My so-called experience is just my personal experience and understanding of electric vehicles after a long ride. Some of the solutions to the problems are handled according to their riding habits, and there are inevitably some shortcomings. Please help us correct them.
According to the development process before, during and after, this paper divides 72 common problems of electric vehicle travel into five parts: travel, vehicle, preparation, riding and aftermath, and introduces personal experience in the form of question and answer. Careful readers will find that most of these questions are raised by netizens in the process of posting, and basically retain the original words of the questioner. Lao Su’s answer now is actually just an enhanced version of the reply at that time. This way of writing aims at strengthening pertinence and facilitating two-way communication and discussion. If netizens keep asking new questions, this article can continue to write back, and I look forward to your advice.
First, electric car travel: there are pains and joys, saving effort and worry.
With the progress of the times, affordable electric vehicles have entered thousands of households and become popular national cars. Traveling by car is a good wish of many electric car enthusiasts, and it is also the yearning and pursuit of a happy life for ordinary people. Old Su’s dream in his later years was no more than that, so he flew first and started a free ride on the motherland with an ordinary electric car. After ten years of hardships and hardships, my friends, including cyclists, motorcyclists and friends, experienced the hardships of the journey together and enjoyed the happiness of the trip. I want to tell you with my riding experience that electric car travel is not a dream, and it is not difficult. You can do it, I can do it, and he can do it. As long as you take the first step bravely, you can experience the fun.
1. In your post, I saw the phrase "Ten years’ hard journey, experience hardships and enjoy happiness". I want to know what hardships electric bicycle travel suffers. What kind of fun do you enjoy?
There are three pleasures in electric car travel: one is more labor-saving, the other is more money-saving, and the third is more satisfactory. Needless to say, riding an electric car saves effort. Even the elderly and infirm like me can ride the Qinghai-Tibet Plateau, and the electric car has made great achievements. Recently, I saw a cyclist playing the banner of "protecting knees, everyone is responsible", and riding an electric car may get twice the result with half the effort.
I have personal experience of saving money. Take SUNRA purchased in 2013 as an example. The price of a new car and two batteries is 3,830 yuan. In 2014, a 12A lithium battery 800 yuan was added, and in 2015, the front wheel motor was added and three 20A lithium batteries were replaced, totaling 5,100 yuan, including the normal maintenance expenses such as tire replacement, about 10,430 yuan. This car was retired in 2016, and it ran more than 35,000 kilometers in 30 provinces and autonomous regions, and rode more than 7,000 kilometers for short-distance and daily use. At the very most, the average riding cost per kilometer did not exceed 0.25 yuan. If we consider that the lithium battery purchased in 2015 was only used for one year (it ran more than 10,000 kilometers in 2017 and will continue to be used in 2018), the average riding cost per kilometer will not exceed 0.17 yuan according to the service life of three-year replacement. Compared with other means of transportation, the cost performance of electric vehicles is still very high. Saving money is the last word, so why not?
The pleasure of traveling is due to the convenience of riding an electric car. It is really a happy life to be able to ride the motherland freely with an electric car. As far as the outdoor travel mode is concerned, it is too slow, too tired to ride a bicycle, too fast to travel and drive by car, and too much scenery is lost. The riding speed of electric vehicles is not too slow, so you can enjoy the fun of riding and the beautiful scenery along the route when you have time. When you are interested, you can also stop to enjoy the fine products and even make some extended in-depth investigations impromptu, which is difficult for other modes of travel. On the Sichuan-Tibet road, I walked with young cyclists. Most of them were exhausted and missed a lot of scenery. At night, they will urge me, "Uncle, hurry up and get on the map, we are waiting to steal it." Can you not be happy in this situation?
The pain of electric car travel is that it is more troublesome. This is due to the characteristics of electric vehicles and the immature riding environment. Electric vehicles are powered by their own batteries, and their endurance is limited. It also takes some time and premise to supplement electricity. Therefore, when planning the trip and arranging accommodation, we should consider the charging conditions, and even get up at night to check the charging situation to ensure safety and full charge.
Second, you will encounter all kinds of difficulties between heaven and earth in long-distance travel. The figure of electric vehicles is relatively delicate, and the riding capacity is far behind that of bicycles and motorcycles. For example, muddy sidewalks, wading sections, rugged mountain roads and windy, rainy and snowy weather all test the condition of the car and the adaptability of the rider. Do your homework beforehand, plan ahead and prepare a plan, so as to avoid being helpless at that time.
Third, the failure of electric vehicles in long-distance travel is inevitable. At this time, it is your luck to have a maintenance point nearby, and you can only stand on your own feet in the middle of nowhere. Therefore, it is also necessary to master some basic knowledge and practical skills of electric vehicles. Therefore, electric vehicles can only save effort, not worry. If you worry more beforehand, you will suffer less when you encounter difficulties.
2, your electric car travel is long and slow, and it seems to be only suitable for the elderly who have time. Excuse me, can working people also travel by electric car?
Traveling slowly by electric car is suitable for people who have time, including middle-aged and elderly people and young people. I saw that most of the cyclists on the Sichuan-Tibet, Yunnan-Tibet and Qinghai-Tibet lines were young people, and it took them about 20 to 30 days to complete their trip to Tibet. Seeing that my riding is relatively easy, many young people try to ride it. Some people say that they will ride an electric car next time they enter Tibet. The outside world is wonderful, but the real life is helpless. Young people have jobs, no time, no time and no job! I understand this kind of distress that it is difficult to leave everything behind and travel far, because I have experienced it. My suggestion is to arrange the immediate work and family life first, and do some short-distance riding when you have time, so that you can warm up for the future electric car trip. Many working people take advantage of fake holidays and annual leave to participate in long-distance cycling activities. You can try it if you have the chance.
In addition, when young people travel by electric car, they can choose faster electric cars, such as power-assisted electric cars and electric motorcycles, so as to save transit time and travel expenses. Lao Su believes that the future of young people is not a dream. Where there is a will, there is a way. I will mount a long wind some day and break the heavy waves, and set my cloudy sail straight and bridge the deep, deep sea!
3. I have been riding an electric car for more than ten years, but I have been afraid to run far, fearing that I will stop eating halfway. I really want to know what difficulties I will encounter when riding an electric car for a long trip. What preparations need to be made in advance?
There are many people riding electric cars in our country, but few people travel by electric cars. The main reason is that they lack confidence in the long-distance travel of electric cars. What difficulties will you encounter when riding an electric car? Generally speaking, it is nothing more than weather, road conditions, cars and pedestrians.
(1) Riding is greatly influenced by the weather, and severe cold and heat, wind, sand, rain and snow are hardships for cars and cyclists. But if you choose the right season to travel, the weather will bring much less trouble.
(2) When riding outside, you may encounter bad road conditions and test your endurance and adaptability. Therefore, it is necessary to do your homework before going out, especially to know the latest road information of the route and choose a better road.
(3) Problems of one kind or another will also occur during long-distance riding. It is very important to choose the right mount. Paying attention to daily maintenance inspection can reduce many hidden dangers.
(4) The cyclist’s physical health and stamina determine how far you can travel by electric car. There are indeed many people who quit halfway because of physical discomfort. Physical fitness, skills and mental exercise are the basis of traveling by electric car. Of course, personal family and economic conditions are also important.
Of course, the above four concerns are not superfluous. These are all part of riding life. Knowing its difficulties and moving forward persistently may be the charm of electric vehicles’ long journey. With the growth of riding experience, these difficulties are no longer obstacles on the road, so you can fully enjoy the fun of electric car travel. As for the specific preparations for riding an electric car, please refer to the introduction at the back of this post.
4. The old gentleman is used to seeing the scenery alone, and riding alone is not afraid of loneliness and homesickness? Traveling is not the best way to do scientific research alone. Don’t you want to have a playmate?
I basically travel by myself, and seldom ride in company. Because a person’s way of traveling has the greatest freedom, there is no need to discuss or compromise, so he can leave whenever he wants, and stop whenever he wants, which is closest to my dream of riding the motherland freely. Although the way of teaming up with many people can increase the riding vitality and enliven the atmosphere on the way, everyone has different personality habits and riding concepts. If they are temporarily combined together, it will inevitably lead to various contradictions and even break up in discord. My cycling route is long, and like-minded cyclists are hard to meet, so I can only go as far as I can. On the 317 and 318 roads, I have made friends with old, middle-aged and young cyclists and walked together for a long or short journey. The premise is that we must give in to each other and give up many of our own ideas. In addition, when many people are together and charging together, they may encounter trouble in the sections with poor power supply conditions.
Riding alone will inevitably make you feel a little lonely and homesick. On my way to the base camp in 2017, I passed the airport and saw the plane take off and land. I was sad for a while and had the idea of going home. I talked to my relatives and friends at night, and they all encouraged me to go on. The next morning the sun was shining and I was in a good mood. Instantly put together a few words:
When the sun sets, you can see the end of the world, the tired birds return to their nests, and the wanderers are homesick.
The sun rises, I want to ride my dream in poverty, get back on the pommel horse and point my sword at Mount Everest.
This is indeed the feeling at that time. I wrote it down in one go, and I have no such inspiration since.
In short, a person can ride as he pleases, and it is relatively easy to charge an electric car. If you don’t have the right teammates to walk with you on the road, and you are unwilling to be lonely, then put yourself in another’s shoes and adjust your mentality. In today’s noisy world, emptiness has become a scarce resource. It’s lucky to ride on a road with few cars and few people, or even enjoy the silence of nature alone, and cherish it!
5, netizens’ expectations for electric car travel and comments from Lao Su
Riding a small tram all over the country, I really admire it! This is our common people’s yearning for a happy life, the happy life of a small tram!
Lao Su’s comments: It is my dream for many years to ride the motherland freely. Traveling with electric cars of ordinary people is much more labor-saving than riding bicycles and hiking. I am full of happiness and on the road.
Being able to ride an electric car through the north and south of the Yangtze River is really a happy life. Brother, the most intimate and grounded trip, has no luxury equipment and no rhetoric. Simple and unpretentious, through thick and thin, I have no struggle with the world, and I have visited China all over.
Lao Su comments: Thank you for your praise! Riding the motherland freely with the most common electric car is my Chinese dream. Only when the civilian electric car travels will more people participate.
Your electric car trip is great! It broke the popular concept that electric bicycles can’t run long distances, and gave the old men and donkeys confidence. When they can’t ride bicycles, electric bicycles also have some fun.
Lao Su comments: It is not difficult for electric bicycles to run long distances, and cars are not the most important. In my opinion, the key point is that people are not confident and prepared enough to travel by electric car. If you have a full understanding of the car condition and road conditions, and make a reasonable riding plan step by step, you can gradually drift away. If my electric car trip can give confidence to the old donkeys, the hardships of riding for ten years will be worth it.
When I was young, I did it for myself. When I was middle-aged, I did it for my family. Now I have to do it for myself. Generally speaking, the whole life is to give birth to our land and raise us! When you are old, you should go around this place under your feet! The old man said that everyone has a heroic dream. This is your dream! Look forward! Go further!
Lao Su comments: Thank you for your blessing! Although happiness comes a little late, electric bicycles can help me realize my dream of cycling in my old age and frailty, and I am fortunate in my life.
Your electric car trip is wonderful, and you enjoy the journey of traveling around China. This is also my dream. I hope Niu Ge can organize a group to ride more places.
Lao Su’s comments: Electric vehicles have become very popular in China. I think it is the most suitable travel tool for electric vehicle enthusiasts. Anyone who is interested in electric vehicles can participate in electric vehicle travel. I don’t have the energy to ride in a group, so I’d better ride along the road.
6, electric car travel under the epidemic situation
In the last two years, the sudden epidemic has greatly troubled electric vehicle travel.
First of all, the uncertainty of the epidemic will affect people’s confidence in traveling and weaken their desire to travel by electric vehicles. Because it is impossible to predict the whereabouts of the epidemic, many riders’ original plans for electric vehicles have been pushed back and forth, and finally they have to run aground.
Secondly, the development of the epidemic will affect the implementation of the cycling plan. Even if you are already riding on the road, you may passively change some paths to get to the end. In 2021, Laosu originally planned to cross the sea and go to the northeast to see the black water. On the way, due to the epidemic in Bayuquan, it was changed to the north. As a result, only the water was seen, but the scenery of Changbai Mountain was not seen.
Thirdly, some epidemic prevention measures will affect the riding mood and reduce the fun of electric car travel. For example, some scenic spots and museums have closed their doors to avoid crowds, and the station, airport and hotel have stricter management measures for passengers, so my free riding is becoming more and more uncomfortable. The decline in the pleasure of traveling will make people think about whether to continue riding.
However, due to the recession and depression of the industry, hotels and restaurants attract customers in various ways. At this time, cyclists who travel enjoy many discounts. The direct benefit is to save accommodation expenses and reduce the cost of electric car travel.
In the face of such an epidemic environment, as a cyclist, we should take the overall situation into consideration, and personal inconvenience should not affect the stability of the overall epidemic prevention. We should consciously abide by the relevant regulations on epidemic prevention and carry out cycling activities in areas where conditions permit. The bottom line is not to add chaos to the country. Personally, I think that, generally speaking, except for the western region where people are less mobile, the riding risk caused by the epidemic will be less, and some long-distance trips can be made, the rest of the central and eastern regions should make arrangements for short-distance riding, and in case of an emergency, they can also return to their original residence quickly to avoid risks. Good luck to everyone!
Second, the choice and configuration of electric vehicles: what suits you is the best.
Electric vehicles are the most basic equipment for travel. It is beyond reproach to choose a car that suits your travel needs, spend money on it, and adhere to the high and low standards or the requirements of Yan Kuan. The electric cars in the specialty store are dazzling, each with its own characteristics. How to choose and configure an electric car that can meet the travel needs? Lao Su had practical experience in buying and using four electric vehicles, and his experience was that he didn’t want the best, but wanted the right one.
7. Ask the landlord: There are many kinds of electric cars running on the road at present. Can they all be used for long-distance travel?
As its name implies, electric vehicles are powered by electricity, and two-wheeled electric vehicles can be divided into electric bicycles and electric motorcycles. Electric bicycles can be pedaled or driven by pure electricity, which has the advantages of portability, flexibility, economy and easy riding. Its limitations are low power, low load and short continuous stroke. Among them, these characteristics of folding electric bicycles are more remarkable. Power-assisted electric bicycle has a similar operation mode to ordinary bicycle. The current supply is controlled by the riding force of people, and the combination of manpower and electricity makes riding feel relaxed and saves electricity, but it requires the rider to have good physical fitness. Electric motorcycles are characterized by novel shape, higher power, faster speed, more complete functions and more comfort, but the price will be more expensive. And belongs to the management of motorcycle category.
Lack of endurance is a common problem of electric vehicles. The power demand of the above types of electric vehicles can be met by simply taking one or two more batteries. I ran more than 6,000 kilometers in seven provinces and regions in the south by riding a folding electric bicycle that I used to go shopping everyday, and more than 16,000 kilometers in 20 provinces and regions in the central and eastern regions by riding an electric bicycle with pedal function. Both of these two cars were originally produced in batches, indicating that the quality of ordinary electric vehicles is reliable enough and can be used for long-distance riding.
8. I am going to start with an electric car for long-distance travel. I have seen the introduction of some brands of electric cars and feel that their performance and quality are good, but I don’t know where to start with which one to choose. Ask brother, how to choose a suitable electric car?
How to choose a suitable electric car? It’s a matter of opinion. Each kind of car has its own length, which can be chosen according to individual needs and specific circumstances. The key is to meet the actual needs of your riding, and the car that suits you is the best. If you have motorcycle riding experience and are rich in silver, an electric motorcycle with fast speed and complete functions is a better choice, which will make your trip more comfortable. If you have good physical fitness and like to enjoy riding, the booster electric bicycle can meet your needs, and its price also has the choice of high, medium and low, depending on your purse. Ordinary electric bicycles and portable electric motorcycles are generally economical. Although they are low in power and slow in speed, they can be used for long-distance travel and daily life at ordinary times. Those with little money can be preferred. If you want to travel by combining riding and riding, a light and flexible foldable electric bicycle is the most suitable.
At present, some cities implement the management mode of registration and licensing of electric vehicles, and generally set some specific standards for licensed electric vehicles. The new national standard in 2019 stipulates that electric bicycles are non-motor vehicles, and the maximum speed should not exceed 25 kilometers. Only 48V, 400W electric vehicles with pedal function can legally go on the road. If you want to meet the needs of travel and peacetime use, you must meet the requirements of these regulations.
As far as my personal experience is concerned, the difficulty in choosing an electric car lies in how to take into account various needs. For example, if you want to have a long battery life, you need to bring more batteries, increase your weight, increase your expenses, etc. Therefore, you should proceed from your own needs and possibilities, taking into account various factors that affect each other, and make choices in a certain order. I have used four electric cars for ten years, and the last three are all bought for long-distance travel. The order of Lao Su’s choice depends on whether the body structure is solid and the size is appropriate; Secondly, understand the configuration of the motor battery; Then check whether the control is flexible and convenient and try to ride; Finally, negotiate the price or modification requirements.
No matter which kind of electric car you choose, the reliability of long-distance travel vehicles must be put in the first place, and problems on the way are the most worrying. I have also experienced the troubles of folding shelves and broken strips on the way. In fact, these problems can be avoided if the reliability of the car structure is taken into account when choosing a car, such as choosing shelves integrated with the car body and tires without straps. Generally speaking, the selection of more mature technology or parts also increases the reliability of use. People usually trust some electric car brands, but they are optimistic that the manufacturers behind them have better production conditions and better products and maintenance services. It is suspected of advertising in this respect, so it is better not to recommend it. As for what style to choose, it is usually decided by personal preference, so there is no need to say more.
9. I can see from the cycling post that you have been riding a small electric car all the time. Why don’t you choose a bigger and more comfortable electric car?
Choosing a mount must proceed from your own reality, and you can’t copy textbooks or other people’s practices. The four cars I have used for travel are all small electric cars, and the bigger and more comfortable electric motorcycles have never entered the eye, and the reasons are not complicated. The starting point for me to choose a small electric car is to solve the problem on my own on a long distance, and the small and light electric car is more convenient to handle. The simplest consideration is that it is easy to get up after falling off the car. Second, the car is small and unobtrusive, which is suitable for my low-key riding mentality. In jindian, the city where motorcycles are banned, it is easy for small electric cars to be lenient when they meet traffic police. Especially when staying in hotels, it is basically allowed to push the room, which reduces the trouble of baggage loading and unloading and charging. Third, according to the current traffic regulations, electric motorcycles that exceed the national standards for electric vehicles should be included in the scope of motor vehicle management and have special requirements for drivers. I don’t have this condition. Fourth, the elevator in my house is very small, and the maximum length is only 1.5 meters. If the electric car is to be placed at home, this length becomes a hard constraint, and the car can only be selected within this range. On the other hand, a small electric car is cheaper than a large electric motorcycle and saves electricity. Reducing travel costs is also an important consideration in car selection.
A netizen commented: choosing a small battery does have a unique advantage. Even cities with power cuts can be unimpeded, and cars that meet the standards don’t have to worry about being fined or something; If there is no electricity, you can ride for a short time without the painful implementation of the scooter; When you encounter a big pit, you can also get on the bus and cross it. The capacity is very high. The disadvantage is that the shock absorption is too poor, and the hands and buttocks on the bad road hurt. It is recommended to focus on improving shock absorption and changing to high-grade seats. In addition, the speed is slow, it takes time to ride, and the amount of daily trips is less. This opinion is still relatively pertinent.
10. The landlord rode different cars in Tibet twice. The first time was an electric bicycle with pedal assistance, and the second time was a small electric motorcycle without pedal. What is the difference between these two cars? Is it better to use a small electric motorcycle? Excuse me, uncle, is this car suitable for girls to ride because of its climbing and shock absorption?
The first Niri electric bicycle I rode in Tibet can be pedal-assisted, and the front and rear drive motors are both 48V250W. The second pure electric blue Emma electric motorcycle has a higher power, with a front drive of 250W and a rear drive of 350W W. Both cars can stand the test of entering Tibet, and there are no problems with the motor, battery and controller, and the quality is up to standard. From the personal riding experience, the first electric bicycle is relatively light and adaptable to various road conditions. Pedaling can not only help, but also achieve the purpose of exercise. The second pure electric small electric motorcycle has better power, relatively easy and comfortable riding, slightly faster speed and power consumption, and the measured data is about +10%. Due to the lack of pedal system, the faults are correspondingly reduced, but the adaptability to complex road conditions is weak and the passing capacity is insufficient.
In the second part of my ten-year cycling summary, there is a comparison of the use effects of these two electric vehicles. Please look back. They all ran past, and Wanshui Qian Shan came, and climbing was a cinch. Among them, the pure electric small electric motorcycle once ran 700 kilometers across the northern Sichuan-Tibet line with a single motor of 350W. The shock absorber and seat bag are better. Because the car is smaller, it is more suitable for girls to ride.
11. Take a long trip with your original Niri electric bicycle. If it is a 350W motor, can it be eaten if you add a pedal when going uphill? I mainly consider that it is not good to add a precursor. There is no such shop in a place like ours, and my hands-on ability is not good. It doesn’t matter if the speed is slower, because I’m thinking about buying it for my wife. I still ride a bike. She’s not physically strong, so I’ll ride an electric one and go with her.
Long-distance travel can be accompanied by husband and wife, which is enviable. Please send your blessings first!
From the riding practice, I used the 250W Nippon Electric Bicycle to run more than 16,000 kilometers in 20 provinces, municipalities and autonomous regions in the eastern and central parts of China in 2013-2014. The motor, battery and controller of the bicycle are well managed without any problems, and the quality and performance of the whole vehicle can be trusted.
Therefore, personally, I think that the original Nippon car, if it is a 350W motor, is much more powerful than the bicycle you ride. When stepping uphill, cyclists with average physical fitness can walk in most areas except Tibet and western Sichuan, while those with better physical fitness can ride into Tibet. But both of them must pay attention to let the motor rest and cool down when climbing. On some steep sections, it is inevitable to push the cart down, so take a rest in the middle of riding.
12. My existing electric car uses lead-acid batteries. According to the online inquiry, it is said that only lithium batteries can be used for long-distance running. I want to hear your opinion. Can lead-acid batteries for electric vehicles run long distances?
Lead-acid batteries are the most widely used batteries in electric vehicles at present. It is economical, safe and reliable. The disadvantage is that the specific capacity is small, that is, under the same capacity, the weight and volume of the battery are large. Lithium batteries are small in size, light in weight and flexible in use, but they are expensive. Generally speaking, long-distance riding is a long way, and there are many luggage items to take, so it is more reasonable to choose a lithium battery with small volume and light weight. Of course, such a configuration will definitely increase a lot of expenses.
As far as your situation is concerned, if you use the existing lead-acid battery electric car to travel far, I think it is also possible. I used two electric bicycles with lead-acid batteries more than ten years ago. One of them is a 36V10A dual battery, which runs 60 kilometers with pure electric energy and can be pedaled. Later, the same battery was added and tied to the column of the car. It can run for 90 kilometers and it feels good to ride. I just had to go to work at that time, so I couldn’t go further because of limited time. When you travel with your existing car, there are at least two advantages, besides the inevitable cumbersome trouble of the car. One is to save a sum of money, and the other is to be familiar with the car and handle it easily.
Before departure, you should configure the battery according to your expected endurance, and the old battery can also be used, but you should carry out a load test under the condition of simulated travel to check whether the vehicle and battery meet the requirements. The long-distance travel of electric vehicles is not only a simple superposition of daily trips, but also some new problems that did not occur in the long journey of old vehicles, such as the wear and failure of some parts, etc., so we should pay attention to observing and checking the condition of vehicles and follow up in time to solve them.
13, Su Lao rode a small electric donkey and enjoyed the great rivers and mountains! I also have this dream, and I have tried it. I ran for 90 kilometers with two sets of 60V20AH lead-acid batteries, and there was no electricity. From this point of view, lithium batteries are still powerful, lead-acid batteries are too bulky, and most of the energy is spent on overcoming their own weight. However, I heard that lithium batteries are too expensive on the one hand, and their safety performance is not comparable to that of lead-acid batteries. I wonder if this is the case?
Generally speaking, long-distance riding is a long way, and there are many luggage items to take. It is more reasonable to choose a small and light lithium battery, which will certainly increase the cost. According to the current price, two sets of 60V20AH lithium batteries will cost about 3,000 yuan. If the economic conditions do not allow, I suggest that we should continue to use the original two sets of lead-acid batteries, and it is not bad to run for 90 kilometers. As long as it is charged for 1-2 hours on the way, it is not a problem to travel 100 kilometers a day, which can meet the general requirements of electric vehicle travel.
In terms of safety performance, I can only make some practical comparisons. I used lead-acid batteries for more than ten years before and lithium batteries for the next ten years. They were all used and charged normally, and there was never any problem. As for how to say it in theory, I don’t quite understand it. You can consult the related posts in the forum and ask other netizens. thank you
14. Isn’t it better to bring more batteries on the road? I think the batteries used by the landlord are all 48V20A, but sometimes they bring three, and sometimes they bring four or two. This arrangement makes people puzzled.
Increasing battery capacity is the main way to improve the endurance of electric vehicles, and more batteries can run farther on the road. However, the weight of the battery itself will also increase and become the total weight burden of the car. Therefore, the battery configuration should be adapted to the expected endurance, not the more the better.
My practice is to do a riding test according to the load standard of travel first, and get the actual battery life data of each battery (new or old). Then, according to the endurance requirements of the two farthest charging locations in the cycling plan, and then multiplied by a certain insurance factor, the endurance mileage required for this long-distance cycling is calculated. Finally, by comparing the cruising range with the actual cruising data of each battery, we can determine how many batteries we need to bring, or even which batteries we need to bring. For example, the two farthest charging places are 118 kilometers from Rumei Town to Zuogong County. After a load-bearing riding test on a mountain road with general difficulty, my 48V20A battery runs 60 kilometers with pure electric energy. Considering that this trip will cross Jueba Mountain and Dongda Mountain, and the total climbing height is about 3000 meters, it is necessary to increase the safety factor by 50%, so at least three batteries should be brought.
All the batteries I use have a capacity of 20A, and each battery weighs about 5 kg. In 2020, if you want to go to Tibet, the road is dangerous and difficult to charge. It is guaranteed to last for 240 kilometers with 4 batteries. In 2021, it is not difficult to go to Mohe in the north. It is enough to travel 100 kilometers a day with 2 batteries. This arrangement can reduce the weight of luggage.
15, the top LS electric car goes to Tibet. When the great gods in some electric vehicle forums are still arguing about what kind of car to ride in Tibet, what kind of configuration and how many ah batteries to bring, you have set an example for them with practical actions. Like one! Also curious to ask: 48V60ah lithium battery is also very heavy, how do you carry it? What is the capacity and size of the battery on the frame?
Long-distance travel needs to bring more batteries. How to place the batteries beyond the original configuration? We should proceed from the reality of different models and take safety and convenience as the principle. Such as electric motorcycles, it is best to use the original battery compartment, or place it after making appropriate modifications, so as to maintain the beauty of the original model and be the safest and most reliable.
There is not much space available for electric bicycles, so it is better to use external fixation. Usually, the battery is fixed on the shelf of the car or on the inclined tube or riser of the car body with a bag of suitable size. Some put the battery in the backpack and connect the power supply when using it, which is also one of the methods. I have used both methods, and I feel that the former method is safer and more convenient. Although it is simple to put in a backpack, it is not convenient enough to use and is not conducive to battery heat dissipation.
As for the practice that some people leave their batteries in the car at will and tie them with ropes before starting, I think it is not safe enough, and it is easy to be scattered during long-distance riding, especially on bumpy roads, which is not desirable.
Specifically, I have equipped three 48V 20A lithium batteries, with a total capacity of 60ah, each with a size of 23x17x8.5cm and a weight of about 5kg. The battery seen on the frame is one of them, but it has become larger after being wrapped with foam board to enhance waterproof and stability. The other two pieces are packed in special boxes and put on the rear rack in the middle of the backpack. All three batteries are movable and can be moved into the room for charging.
16, brother, the biggest expense on the road is accommodation. You can make a tricycle with solar panels, and you can eat and live in the car. Isn’t it much cheaper?
Solar electric car is a very creative new thing, and some electric car enthusiasts have begun a bold attempt. 8264.com also published their innovative cycling diaries. Thank you for your advice! So far, the technology of applying solar panels to electric vehicles is not mature and the cost is too high. My opinion is:
(1) Long-distance running by electric car is not the most economical way to travel. From the point of view of convenience and labor saving, it is more reasonable to charge when staying.
(2) Don’t expect too much to supply power to the solar panels of tricycles. It is good to provide 1/3 of the power, mainly relying on batteries and conventional charging.
(3) The dead weight, power consumption and failure rate of tricycles are higher than those of two-wheeled vehicles. Solar electric vehicles have higher requirements for cyclists in electronic technology.
(4) The passage of solar-powered tricycles in some sections is restricted.
Therefore, Lao Su will not choose a tricycle with solar panels for his trip.
17. I didn’t see a spare tire hanging behind the car on this trip. Is it not necessary to bring a spare tire with anti-puncture? Do you think it is reliable to prevent puncture after your long-distance travel experience of electric vehicles over the years?
Tire puncture is a common fault in long-distance travel of electric vehicles. Especially in Xinjiang, where there are many heavy-duty trucks, it is very troublesome to stop and repair tires frequently. In order to reduce or avoid the risk of puncture, I have tried to use solid tires, but riding feels uncomfortable. Only by using vacuum tires can we get better results. Because the front wheel can’t be equipped with vacuum tires, we can only choose real king kong tires, while the rear wheel uses brand-reinforced vacuum tires. In this way, the problem of puncture on the road that has been bothering for many years has basically been solved.
The advantage of using tire puncture prevention is that it can reduce the failure of small iron wire puncture. Touch the puncture-proof surface with your fingers, and there will be some small residual iron wires, but the wheels will not leak. But it can’t resist sharp objects such as larger nails. When I was riding the Everest Line in 2017, I was punctured by a spike, so I had to return it and repair it before continuing my journey.
As for whether to bring a spare tire? I will consider two points: first, the road conditions are good or bad, and second, the supply of spare parts is difficult. You don’t have to bring the conditions, but you have to bring them. That’s why you see the spare tire hanging or not hanging behind the car.
18. The electric vehicles mass-produced by manufacturers have already met the national standards. Why should they be modified?
In the related websites of electric vehicles, there are many posts about the modification of electric vehicles, and the discussion is heated. From a practical point of view, businesses that operate electric vehicle maintenance services are also prosperous in refitting electric vehicles. Not to mention those players who think that electric cars are not only for riding, but also for tossing for fun.
According to the national regulations, the speed, vehicle weight, motor power and voltage of electric bicycles managed by non-motor vehicles should not exceed 25km/h and 55kg, respectively. This standard is feasible for electric vehicles with pedal riding ability to travel in most parts of China. In 2012-2014, Lao Su traveled more than 23,000 kilometers in 22 provinces in eastern and central China by electric vehicles below this standard.
However, for riding on the long slopes of the Qinghai-Tibet Plateau and the steep mountain roads of the Yunnan-Guizhou Plateau, the motor power of 400W is definitely stressful, and it is difficult to meet the requirements of long-distance travel. Therefore, from the actual needs of long-distance travel of electric vehicles, it is understandable to increase the speed and power, otherwise it will be difficult for electric vehicles to travel long distances and enter Tibet and Xinjiang. Even if the electric vehicle meets the national standards, it is necessary to modify some components, such as lighting, seat bag, stereo, etc., from the perspective of safety and comfort during long-distance travel. The improvement of the body appearance may also highlight the rider’s personality. Therefore, the modification of electric vehicles will be enjoyable.
19. How was your electric car modified? What aspects should be paid attention to when refitting electric vehicles? Where can I refit an electric car?
In the first three years of long-distance cycling, I used the original electric bicycles mass-produced by manufacturers, which greatly enhanced my confidence in riding electric bicycles to visit the great rivers and mountains of the motherland. But at the same time, I also personally experienced that electric vehicles are limited by battery capacity, and the freedom of riding is limited; Because the motor power is small, it is difficult to climb a mountain hundreds of meters high.
In order to realize my dream of riding on the Qinghai-Tibet Plateau, I have made some necessary modifications to the electric bicycle that has been running for two years. The original car was equipped with 48V/250W motor, with single rear wheel drive. The power for climbing the big slope of Sichuan-Tibet railway was definitely insufficient, so the front wheel drive was added in a targeted way to improve its climbing ability. The modification does not involve the operating system of the original car, but a 48V/250W motor is newly installed on the front wheel, with its controller installed on the front column and its starting handle installed on the left. After the modification, the front and rear wheels have a set of drive systems, each using a set of batteries, which are controlled by the left and right hands respectively, and can run independently or start at the same time.
The problems that should be paid attention to in refitting electric vehicles are as follows: First, the clearer the target of refitting, the better, and what to change and to what extent. Second, the simpler the modification, the better, and the less impact on the structure and operation of the original car. Third, it may take a period of adaptation to get used to its operation method after modification.
It is not complicated to modify electric vehicles, and businesses that sell electric vehicles can generally provide maintenance services and modifications.
20, brother would like to ask, you added a front motor, is it one-drive two motors or two-drive two motors? And what are the benefits of adding precursors?
The motivation of increasing front-wheel drive is that the original 350W rear-wheel drive has insufficient power when climbing large and long slopes. The scheme of increasing the power of front drive instead of rear drive is mainly considered from three aspects:
First of all, I have learned from many years of riding practice that the original drive system of the car is the most reliable, and there have never been any problems with the original motors, batteries and controllers of the three small trams used for long distance. The places that are prone to failure are all from the modified part. Therefore, considering the reliability, it is not appropriate to change the original drive system easily, which is the main reason for adopting two drives and two motors.
Secondly, the independent front wheel drive system is adopted, and the circuit is simple and clear, and the installation and maintenance are convenient.
Third, the front and rear wheels can be driven independently, which means that with backup, the east is not bright and the west is bright, which can improve the safety factor. I was on the road twice in 2015 and 2019, and the front wheel drive failed, which was to get out of the predicament by rear wheel drive.
21, I would like to ask, how can the front and rear drives be used reasonably? Does the flat road rotate back and forth? Did you turn off the power supply of the other one during the rotation? Is it dual drive when going uphill?
It is estimated that you have driven a dual drive, because your question is very real and contains some answers. How can the front and rear drives be used reasonably? My experience is to foster strengths and avoid weaknesses, and try to give full play to its advantages. The rear drive is the original 350W Bosch motor, which has good quality and great strength, and is stable in operation. It does most dirty work, such as walking bumpy roads and climbing hills. The front drive is a 250W high-speed motor, which saves electricity and is faster, but its strength is a little weak. It is just right to arrange it to run flat roads and good roads, and it performs better. Therefore, it is necessary to rotate back and forth according to the road conditions.
When I rotate the motors, I don’t have the habit of turning off the power supply of the other one, and I keep a state of free switching at any time to cope with the sudden situation that may occur on the road. As for going uphill, if the slope is not big, you should use single rear drive. If you can’t get up, you should use double drive. If you encounter abnormal slope, you should come down and push the cart.
22. Excuse me: After installing the front wheel motor, can the front and rear wheels be synchronized when starting at the same time? If it is not synchronized, how do you handle it?
The power of the front and rear wheel motors of my car is different, and the speed of the front and rear wheels will be different when starting, which means that the speed is not synchronous. It will form resistance, leading to increased power loss of front and rear wheels. Synchronization technology can solve this problem pertinently, but it is costly and difficult.
The front and rear wheels of my car have a set of independent drive systems (motor, battery, controller), which are controlled by the left and right hands respectively, and can run separately or start at the same time. At the same time, the rotation speed of the front and rear wheels is not necessarily synchronous when starting, but it is not a big problem, because the rotation of the front and rear motors can be sensed by holding the knobs with both hands. If the double motors run briskly and there is no noise, it indicates that the front and rear wheel speeds are synchronous or relatively synchronous, and no adjustment is needed at this time. If the operation of the double motors is blocked, it will produce some noises and vibrations, which indicates that the speed of the front and rear wheels is not synchronized enough. At this time, it is necessary to slightly adjust the power intake of the left handle or the right handle, so that the motors can eliminate noises and vibrations and return to light operation, which indicates that they have returned to a synchronous or relatively synchronous state. This ability to judge and adjust requires some practical experience.
Third, the preparation before the electric car travels: know yourself and know yourself, and plan ahead.
Electric cars travel long distances, the road is long and wild, and there are many unknowns along the way. The problem to be faced is more complicated than riding a bicycle. The car condition, road conditions, weather and accommodation conditions are all restricted. It is not easy to leave when you say it. The more prepared you are before you leave, the greater the possibility of success. Sun Tzu said in the Art of War, "Know yourself and know yourself, and you will be invincible; Knowing each other and knowing each other, one wins and one loses; I don’t know each other, I don’t know my friends, and every battle will be ruined. " Do all the preparatory work before going out, know yourself and yourself, and plan ahead, so as to improve the success rate of riding and be invincible.
23. Why do you want to carry out vehicle testing? How to test the vehicle?
How to know yourself when riding an electric vehicle? From the main requirements, the focus of knowing each other is to fully understand and master all kinds of information on the road. The key of confidant is to be familiar with the performance characteristics of the car and know what the car can and can’t do. Among them, vehicle testing is the basic method to understand the car. Pay attention to three points in the test process:
(1) The car to be tested should ride on a mountain road with general difficulty according to the daily travel arrangement and luggage load, and it is generally appropriate to ride for about 4-5 days and 500 kilometers. In this way, you can have personal experience of loading and unloading luggage, choosing accommodation and charging, and the obtained data and experience are more practical and useful.
(2) There are three aspects in the test. One is the dynamic situation of the car, which mainly depends on its speed and climbing ability. The second is the handling of the whole vehicle, such as steering, braking and stability. The third is the adaptability of cyclists to walking for 100 kilometers in a row.
(3) The daily trip record should be made in the test, especially the kilometers when climbing the hill and changing the battery. After recording for many times, it will be sorted out, and some regularity of power consumption will be gradually discovered, so as to be aware of it.
If you can really be a "bosom friend", according to Sun Tzu’s saying, "Know the enemy without knowing the other, one wins and one loses", you have already succeeded half the battle. Every time Lao Su travels with a new car, he goes through hundreds of kilometers of riding tests. Before getting on the 318 line, I specially selected lakes with similar road conditions as test sites to test the adaptability of the car and myself riding on the plateau, laying a solid foundation for riding electric cars into Tibet in the future.
24. The places my brother goes every year are wonderful and desirable. How do you make a cycling plan?
As the saying goes, sharpening a knife does not miss the woodcutter. Spending some time collecting relevant information before going out is the basis for making a cycling plan. It is necessary to know as much as possible about the latest situation of road conditions, weather, accommodation and power supply in the planned trip, and pay special attention to the altitude changes and sudden disasters in the route. Most of this information can be found on the Internet. The latest information should pay special attention to cyclists who have just come from this section, and its information is especially timely, accurate and reliable.
Regarding cycling routes, there are many recommendations on the Internet, such as the top ten gold cycling routes, which can be used as a reference. But before and after the starting point, we also need to supplement and improve ourselves. Lao Su yearns for free riding and likes to be arranged by his own will. The usual practice is to connect the most wanted places such as Huizhou, Hukou and other places as nodes, and then consider the rationality of the trip in combination with the supply conditions along the route and the endurance of the car. Finally, it will become a cycling route with a little adjustment.
Riding an electric car should be within the cruising range and know the car condition and road conditions. It should be a basic common sense of electric car travel. If you are not fully prepared, don’t go where there is no electricity or no people. When riding in Xinjiang in 2018, it was originally planned to go north to Altay by National Highway 216. However, considering that there is no guarantee for accommodation and charging in the Gobi Desert, which is more than 280 kilometers from Jimsar to Qia Courtou Town, it was changed to Shihezi and headed west.
There are many unpredictable factors for long-distance riding, such as car condition, road condition, weather and accommodation conditions. It is not easy to leave when you say it. The more prepared, the more likely you are to succeed. For example, climbing has a great influence on the endurance of electric vehicles, so pay special attention to the height change in road conditions when doing homework. In this regard, Google Satellite Maps is a good helper. There are two roads from Hami City to Barkun County to cross the Tianshan Mountains. The right line takes Provincial Highway 303 and the left line passes through Tianshan Temple. Navigation shows that the right lane is 10 kilometers longer than the left lane. However, according to the image analysis of satellite map, the right pass is about 2200 meters above sea level, and the left pass is about 2700 meters above sea level. Everyone knows the pain of climbing, so it is wiser to choose the right line.
A good riding plan should be realistic and flexible. For electric car travel, the accommodation is not only a resting place for cyclists, but also undertakes the task of charging. According to the estimated power consumption and power supply during the trip, arrange the accommodation and charging places, and have feasible alternatives. The difficulties that may occur in key sections need to be followed up at any time and pre-judged in time. Riding the northern Sichuan-Tibet line in 2019, I originally planned to stay in Jueen Township, but when I arrived, I learned that all the hotels were closed, and the original owners had gone to dig Cordyceps. This situation was unexpected, so I had no choice but to make changes. Fortunately, time and electricity were still relatively sufficient, so I moved on to Dingqing County. Therefore, the choice of accommodation on the way also needs multiple alternative points, which makes the plan flexible. If you encounter a road section that exceeds the capacity to continue, you need to replenish electricity on the way, you must make a specific place and time arrangement for charging, so as not to be in a hurry when there is no electricity on the road.
As for some long routes, they can also be completed in stages. For example, I took the Silk Road to Xinjiang in 2018, and rode the New Tibet Line to Kashgar in 2019. In fact, it is also a 15,000-kilometer-long Kashgar-Guangzhou Ring Road, but its line is too long and it has been completed in two years. This can reduce the route difficulty, reduce the riding pressure and improve the success probability.
