1. Difference in service life The service life of the battery is the most concerned point for consumers when purchasing. At present, the average service life of lead-acid batteries is about 2 years, and the number of cycles is between 300 and 500 times; the average service life of graphene batteries is about 3 years; lithium batteries have a longer service life, with a cycle number between 700 and 1000 times, and the battery can be replaced every 4 years. In the past two years, the spontaneous combustion caused by Used Car batteries is mainly caused by Used Electric Car equipped with lithium batteries, especially many small workshops that privately make lithium batteries. Because the density of lithium batteries is large and the heat resistance is poor, if it is overheated, such as in summer or charging for too long, exceeding the load temperature, it may cause spontaneous combustion, especially inferior lithium batteries should be more cautious in safety. Lead-acid batteries are relatively stable and generally rarely spontaneously combust. 2. Difference in safety performance Degree, it may cause spontaneous combustion, especially inferior lithium batteries should be more cautious in safety. Lead-acid batteries are relatively stable and generally rarely spontaneously combust. 3. Warranty difference The warranty period of Used Car batteries is an important standard that car owners can refer to when exchanging for other batteries. The warranty periods of lead-acid batteries, graphene batteries, and lithium batteries are very different. Generally, lithium batteries have the longest warranty period. 4. Battery maintenance tips Plug in

In the hot summer, the outdoor temperature is high. Hot weather is gradually recurring. Therefore, Used Car should pay more attention to travel safety. Let's take a look with Used Electric Car franchise manufacturers. 1. Avoid exposure to high temperatures and scorching sun. Avoid charging in high temperature environments in summer. When the battery is charged, heat will be generated, which will increase the battery temperature. If the charging environment temperature is high, it is easy to reduce the battery life. 2. Don't ride Used Car when it rains heavily. Just don't park your car in an open environment, because the electronic components of Used Car are very afraid of water ingress. Minor water ingress only needs ventilation and drying; but if it is more serious, you need to go to a repair point. Used Car are prone to damage motors and controllers when they enter the water. Citizens should pay special attention to the depth of water accumulation and never exceed half of the wheel. 3. Don't be impatient and avoid sudden braking Summer should also try to avoid sudden braking. When accelerating, especially when starting, you should slowly turn the handlebars, and sometimes you can stop for a while, and then continue to accelerate when the speed comes up. 4. Avoid storage with low power. When the battery is not in use, it should be fully charged and placed, and the main circuit switch should be disconnected. In addition, the battery should be recharged once every 1 to 2 weeks, which can extend the service life of the battery. 5. Check regularly. During use, if the range of an Used Electric Car suddenly drops by more than ten kilomete

Summer is here, and Used Car charging needs to be paid attention to at all times. In a high temperature environment, improper charging may cause battery damage and safety hazards. Therefore, we need to keep in mind some precautions for charging in summer to ensure charging safety and battery life. 1. Avoid charging in a high temperature environment Charging in a high temperature environment will increase the temperature of the battery body, which may affect the life of the battery. Therefore, it is not recommended to charge during the peak hours of noon or afternoon in summer. Choose to charge in the cooler morning or evening. 2. Choose a regular charging station There are many charging facilities on the market now, but not all facilities can guarantee safety. We recommend choosing a regular charging station or a branded charging station to charge to ensure the reliability and safety of the charging facilities. 3. Avoid long-term placement at room temperature High temperature environment will further intensify the chemical reaction inside the battery, and long-term placement will cause problems such as battery heating and leakage. Therefore, when the battery is not used for a long time, it should be placed in a cool and dry place for proper storage. 4. Do not charge the battery for a long time After the battery is fully charged, it will continue to charge, which may damage the battery. Therefore, we recommend avoiding charging the battery of the Used Electric Car to protect the battery. In short, when charging Used Car in the summer, we need to pay attention to the safety and life of the battery, avoid charging in high temperature

When going to work in the morning, you often see many elderly people or parents driving Used Car to send students to school, but this kind of Used Electric Car often fails. Let us learn about the common faults of Used Car. The noise of Used Car is a common problem. The main reasons are large bearing clearance in the motor, motor rotor sweeping, loose and falling magnets, axial movement inside the motor, oxidation, ablation, oil pollution, uneven surface of the brush motor commutator, and loose commutator segments. The failure of the instrument panel to display is also a common fault of Used Car. The main reason for the failure is that there is no voltage between the positive and negative leads of the instrument, the wire or connector is short-circuited, or the instrument is damaged. If the Used Electric Car is powered on, the wheels will turn, and the incremental speed is very fast. This fault is called flying car, which is mostly caused by the poor contact cycle of the ground wire of the turn handle, or it may be a controller failure. The out-of-control horn of the Used Electric Car is mostly caused by damage to the horn, damage to the switch, or short circuit of the connecting wire or connector. These aspects are mainly checked during maintenance.

With the development of society, Used Electric Car are very common on the road, and the demand is increasing, but many people don’t know how to choose a manufacturer. So how should we choose a suitable Used Car manufacturer? Today, let me give you a brief introduction. 1. When we choose an Used Car, we need to reasonably estimate the price and economic strength, and make comprehensive considerations, such as the performance of the whole vehicle, the mileage, how often maintenance is done, the power consumption per 100 kilometers, the maximum speed, the power of the motor, and if conditions permit, we can test drive and feel the performance of the car and its climbing ability. 2. Consumers should choose brands and manufacturers with long operating time, low rework rate, good quality and reputation. Generally speaking, Used Car manufacturers with a certain scale and a long operating time can ensure that our after-sales service is guaranteed. 3. Understand the after-sales service and emergency service of Used Car. Problems such as how to repair the parts of Used Car when they fail. Understand the after-sales reputation and credibility of the manufacturer. If the Used Car runs out of power halfway, whether emergency service support and charging service are provided, and how long is the response time. 4. After purchasing an Used Car, you must collect and properly keep the accessories, invoices, chargers, certificates of conformity, instructions, warranty cards, etc. that come with the car. Some Used Car manufacturers have established a user filing system. Please file according to the instructions so that you can enjoy after-sales service.

1. If the Used Car is not used for a long time, the battery should be fully charged and stored, and it should be charged once every half a month, and the charging time is about 9 hours; 2. When the capacity of the Used Car battery drops sharply, a new battery must be replaced. Batteries of the same brand, capacity, and similar voltage (after full charge, the voltage difference does not exceed 0.1V) must be grouped together; 3. No objects are allowed to be placed above or below the battery, and the positive and negative poles of the battery cannot be directly connected to prevent short circuits and damage to the battery; 4. After the Used Car battery is discharged, please recharge it in time, otherwise the battery life will be affected; 5. The surface, connecting wires and bolts of the Used Electric Car battery should be kept clean and dry for a long time; 6. The battery connection must be kept in good condition. Check the fastening nuts of the battery connection frequently to see if they are loose to avoid sparks or burning the poles.

1. Use the original optional charger when charging, otherwise it will easily affect the life of the power battery or even cause damage. 2. Please use the specified lubricant. 3. Please slow down and drive carefully on rainy days or on roads with water accumulation. If the motor system is damaged by water due to wading, it will not enjoy the quality assurance service. If you treat it well, it will treat you well. Just pay a little attention to these matters that must be paid attention to, which can help you use Used Car better and keep your Used Car as good as new. 4. Please do not change the structure of Used Car or add accessories other than the plateau design (such as adding leaf springs, adding electrical equipment, etc.) without authorization, otherwise the faults caused by them will not enjoy the quality assurance service. 5. Used Car are prohibited from overloading and speeding. Try to avoid sudden braking, as well as emergency braking when driving at high speed. Please pay attention to ensure that the tire pressure is within the specified value range. 6. When driving, avoid sudden starting and sudden acceleration to prevent safety accidents. The charger must use original accessories, otherwise it is very likely to cause the Used Electric Car to fail to work properly. 7. When the Used Electric Car actually travels 2000-2500km, mandatory maintenance must be carried out, and then three routine maintenance must be carried out every 1000km.

Used Car can be driven in heavy rain. At present, the "Safety Requirements and Test Methods for Power Batteries for Used Car" clearly stipulates relevant safety indicators and test methods. Both the country and enterprises have made a lot of efforts in the safety of Used Car electricity use. At the same time, the protection level of most mainstream cars of Used Car manufacturers has reached the IP67 level of the civilian standard. Therefore, as long as the Used Electric Car is purchased from a regular Used Car manufacturer, the safety requirements of its power battery are much higher than the usage scenarios we encounter in our daily life. When there is water accumulation on the road section that must be passed, it can be considered to pass when the water depth does not exceed 0.5m. If it exceeds 0.5m, it is not recommended to wade through the water, and the speed should be kept at a constant speed. After wading, Used Car manufacturers recommend that the vehicle be parked in a dry environment. When starting next time, pay attention to whether there is a fault alarm. If there is a fault, it must be solved before driving. If it rains suddenly while charging, don't worry, the charging port is waterproof. At the same time, the internal system of the Used Car will detect the charging status and environment in real time, and will start automatic protection if there is an abnormality. If the charging port is flooded during rain, it is not recommended to charge. Also note that before each charging, you should check whether there are signs of burns on the charging port or charging gun. If you find any abnormalities, do not continue charging and wait until the problem is resolved befo

Used Car are pollution-free and low-noise. Used Car do not produce exhaust gas when internal combustion engine cars are working, and do not produce exhaust pollution. They are very beneficial to environmental protection and air cleanliness, and are almost zero pollution. Used Car do not produce noise generated by internal combustion engines, and the noise of electric motors is also smaller than that of internal combustion engines. Used Car have high energy efficiency, especially in urban operation, where cars stop and go and the driving speed is not high, Used Electric Car are more suitable. Used Car do not consume electricity when they stop. During braking, the motor can automatically convert into a generator to realize the reuse of energy during braking and deceleration. Used Electric Car have a simple structure, fewer operating and transmission parts, and are easy to maintain. When using AC induction motors, the motors do not require maintenance, and more importantly, Used Car are easy to operate.

Used Car are energy-saving and environmentally friendly, safe and reliable, low-cost, comfortable and flexible, and have many advantages, such as no pollution and low noise. Compared with internal combustion engine vehicles, Used Car do not produce emission pollutants when working, and the noise generated by the drive motor when working is also less than that generated by the internal combustion engine. Used Car have high energy efficiency, and their energy utilization efficiency has exceeded that of gasoline engine vehicles, especially when running in the city, the car stops and starts, and the driving speed is not high, Used Car are more suitable. Used Car do not consume electricity when they stop. During the braking process, the motor can also be automatically converted into a generator to realize the recycling of energy during deceleration braking. Used Electric Car have a simple structure and are easy to use and maintain. Used Car have a simpler structure than internal combustion engine vehicles, with fewer operating and transmission parts, and less maintenance work. When using AC induction motors, the motor does not require maintenance, and Used Electric Car are easy to operate.

Before driving Used Car in rainy days, the vehicle condition should be checked. Before driving, pay attention to the real-time weather forecast and make timely preparations for rain protection. Check whether the brakes, wipers, lights, horns, steering gears, fuse boxes and other parts are normal. Drive carefully. When driving in rainy days, you must slow down and drive slowly. For unfamiliar roads, you must drive along the route taken by the car in front. When charging Used Car, observe the charging head and charging base. They must be kept dry and free of ablation, and avoid charging in the open air on rainy days. After the Used Electric Car is charged, when disconnecting the charging connection device, your hands must not be wet, otherwise it may cause electric shock and personal injury. After wading, Used Car are the same as traditional vehicles. In addition to storing water, check the chassis, especially the braking system, and pay attention to the inspection of the power battery, motor and power harness. When maintaining Used Car, the battery pack, battery voltage, SOC power, battery temperature and other connection conditions are generally tested, and if a fault occurs, it will be remedied in time. In order to avoid the danger of electric shock and leakage, the charging interface of Used Car should be checked regularly. You should also pay attention to protecting the charging port at ordinary times. Remember to close the charging port after charging. Otherwise, it will be exposed to the outdoors, which will accelerate the aging of the charging port. Although Used Electric Car do not have engines, they have electric motors, so they also need to replace gear oi

1. Start slowly and accelerate, avoid violent driving methods such as sudden acceleration, sudden deceleration, sudden turns, and sudden braking; 2. Maintain medium and low speed driving (60-80km/h, try to keep it in ECO mode), avoid speeding and overloading; 3. Plan your trip and try to reduce the load of Used Car to increase the range of Used Car; 4. When the Used Electric Car power is close to 30%, it should be charged in time. If the Used Electric Car often continues to drive when the power is less than 10% (some Used Car will enter the speed limit state), it will cause over-discharge damage to the power battery; 5. It is best to charge every day, just like we use mobile phones every day. Insisting on charging every day can improve the activity of the battery, and often waiting until it is out of power to charge will reduce the battery life; 6. When the Used Electric Car is idle, the battery power should be ensured and the battery should be charged regularly.

The battery life has also been greatly improved. The life of lithium-ion batteries in Used Car depends on the charging method. Under normal circumstances, if the battery is fully charged and the vehicle is driven until it is 100% discharged, if it is recharged, the number of cycles is about 1,000; if 50% of the battery power is used and then recharged, the charge and discharge cycle becomes 5,000 times; if everyone charges as they use, the maximum charge and discharge cycle is 8,000 times under normal use. It is said that the current battery life can be used for about 20 years. (1) Battery performance depends on the battery management system Another "key" to determining battery performance is the battery management system (BMS). The BMS is usually designed to be integrated with the battery and is also included in the integrated power control unit (EPCU). It monitors the battery's charge and discharge status, and when the battery detects an abnormality, it automatically connects or disconnects the battery power through a relay (a device that opens and closes other circuits in certain circumstances). It also allows the battery management to reduce performance at low temperatures. (2) The drive motor achieves self-charging Another major component of an Used Electric Car is the "motor". It is actually part of the engine, converting electrical energy into kinetic energy and storing it in the battery. The same is true for deceleration while driving, which is called a regenerative braking system. Currently, some Used Car such as Hyundai, Kia, and General Motors are equipped with devices that can gradually adjust regenerative braking. (3) Speed ​​reducer is equivalent

With the increasingly serious environmental pollution problem and technological advancement, the popularity of Used Car is accelerating. However, Used Car have limitations, that is, they cannot get rid of the impression of "city cars", with short cruising range and long charging time. But as Used Car become more popular, battery prices fall, making Used Car affordable for more people. (1) An increase in battery does not mean an increase in battery life. There are still many questions about Used Car. In fuel vehicles, the "engine" is the key component, and in Used Car, the "battery" is the key to Used Car. The battery is a component that stores electrical energy and corresponds to the fuel tank of an internal combustion engine. The driving range of an Used Electric Car usually depends on the battery capacity. But simply increasing battery capacity won't increase range. This is because the size and weight of the battery will also be affected. (2) The development direction of batteries is small size, light weight and high capacity density. This is why manufacturers are keen to improve the efficiency of EV batteries. To effectively increase the driving range of Used Car, the energy density of batteries needs to be increased. It is small and lightweight and must store electrical energy as efficiently as possible. As battery technology develops, recently launched Used Car have greatly improved energy density. As a result, current Used Car also have significantly greater range on a single charge compared to the original Used Car.

After buying a new Used Car, many people don't know when to charge the car, and don't know the time of charging. Mastering the time is very helpful to extend the service life of Used Car batteries. Let the Used Car manufacturer introduce the charging time of Used Electric Car. 1. Under normal circumstances, Used Electric Car are generally charged when they are about 70% of the mileage in the instructions. It can not only prevent the problem of initial battery capacity loss, but also prevent over-discharge. 2. If the Used Car often carries people and climbs hills, we need to charge the Used Car after driving it to half of the mileage in the instructions. 3. If you drive it very little, and you haven't driven it to two-fifths of the mileage in a week, you need to charge it once. 4. If the Used Car is not used for a long time due to going out, it is recommended to charge it once a month. The above is the charging time for Used Electric Car, but remember that no matter what the situation is, the battery charging time should not exceed 8 hours, especially in the cases mentioned in the third and fourth points above, the charging time should not exceed 5 hours.

1. Used Car are energy-saving and environmentally friendly, green and pollution-free. Used Car do not cause pollution during operation, unlike Fuel Car that emit gases such as nitrogen dioxide, which is beneficial to environmental protection. 2. Used Car can also be charged at night when electricity consumption is low, making full use of electricity resources and balancing the quality of power supply in the power grid. On the one hand, it can save costs. In addition, it can also produce good social benefits and obvious environmental benefits. 3. Used Car have a simple structure and are easy to operate and maintain. It is convenient for middle-aged and elderly people to learn, and its speed regulation system can also complete very stable speed regulation, run smoothly, and ensure safe and stable driving. 4. Used Car have a reverse gear driving function. Compared with Used Electric Car, reverse driving can be easily completed, and there are voice prompts, which is very practical in narrow alleys and lanes.

As the range of Used Car gets longer and longer, the battery capacity gets larger and larger. However, although the range has been improved, other problems have arisen. For Used Car, we should not only pay attention to the range, but also the charging time. So how long does it take to charge an Used Car? 1. The general charging time of Used Car on AC charging piles is 6-8 hours, and DC charging piles take about 30 minutes to charge 80%. Due to the different capacity and performance of car batteries, the charging time will also be different. Different temperatures will also affect the charging time of Used Car. During the charging process, car owners need to reasonably control the charging time to avoid overcharging. 2. Fast charging and slow charging are relative concepts. Generally, fast charging is high-power DC charging, which can fully charge 80% of the battery capacity in half an hour. Slow charging refers to AC charging, and the charging process takes 6 hours to 8 hours. 3. The charging speed of Used Car is closely related to the power of the charger, the charging characteristics of the battery and the temperature. At the current level of battery technology, even fast charging takes 30 minutes to charge to 80% of the battery capacity. After exceeding 80%, in order to protect the battery safety, the charging current must be reduced, and it will take longer to charge to 100%. 4. When charging the battery of an Used Electric Car, flammable gas will escape. Therefore, charging must not be done in a narrow, sealed environment. Choose ventilation and waterproof, and the ambient temperature should not be too high. Community charging piles are more suitable, and car owners sho

Used Car tires are a very important part of Used Electric Car. When conducting daily inspections of Used Electric Car, you should pay attention to checking whether the tires are normal, and you should also pay attention to daily maintenance. Then in the next time, our Used Car manufacturers will talk to you about tire maintenance. 1. Under normal circumstances, for all cars, the tire pressure is generally not less than 1.8bar and not higher than 2.6bar. Now many cars can reach 2.8 or 2.9. But you have to be clear that the standards for each car are actually different. The tire pressure of each model will be written on the nameplate of the co-pilot. You can look at the nameplate of the co-pilot to understand what the normal tire pressure of your car should be. For larger cars, the tires are larger and wider, and the tire pressure will be slightly higher. 2. The tires of Used Electric Car need to be degreased in time. Oil stains will cause aging and deterioration. If they are stained with oil, they should be cleaned in time; check the tire valve core frequently to prevent air leakage, so that the tires can maintain a normal range of tire pressure; do not overload. 3. Used Car should be fully inflated when not in use. If the tire pressure is too low for a long time, it will cause the tire to crack and deform, reducing the tire life; if it is not placed in a humid place, it will accelerate the aging of the tire; if it is not placed under the scorching sun, it may cause a blowout or accelerate the aging of the tire; if it is not used for a long time, it should be covered with a plastic bag. 4. The situation of each person and each car is different. T

Now more and more people are using Used Electric Car in life. Compared with traditional fuel vehicles, they are more environmentally friendly, so they are more popular. So how many kilometers can an Used Car like this run? Let's give you a brief introduction today. 1. Used Car (BEV) refer to vehicles that use on-board power as power, use motors to drive wheels, and meet the requirements of road traffic and safety regulations. At present, Used Car can run up to about 500 kilometers, and most Used Car can run more than 200 kilometers. 2. After the Used Electric Car is proposed, the power must be replenished in time to keep the battery in a full state. During use, the charging time must be accurately grasped according to the actual situation, and the charging time must be grasped by yourself according to the usual frequency of use and mileage. During normal driving, if the power meter indicates that the red and yellow lights are on, you should go to charge. 3. If only the red light is on, you should stop running and charge as soon as possible. Excessive discharge will shorten the battery life. The charging time should not be too long, otherwise it will form overcharging and make the vehicle battery hot. Overcharging, over-discharging and undercharging will shorten the battery life. During the charging process, if the battery temperature exceeds 65°C, charging should be stopped. 4. The battery must not be placed in a sealed container, close to an open flame, thrown into a fire or immersed in water, and is strictly prohibited from direct exposure to the sun. During the use of Used Car, it is forbidden to step on the accelerator (throttle) hard. T

With the development of society, Used Car have become more and more popular in recent years, but some people have raised questions about what advantages Used Car have over traditional Fuel Car. 1. Compared with traditional Fuel Car, Used Car are easy to operate, simple in structure, and have relatively few running transmission parts. There is no need to replace engine oil, oil pumps, silencers, etc., and there is no need to add cooling water. The maintenance workload is small. If there is a good battery, its service life is longer than that of Fuel Car. 2. The significance of Used Car for environmental protection is that it changes the dependence of automobiles on fossil fuels, has the opportunity to ease the oil crisis, and will also change the energy structure of society. That is, when the proportion of thermal power decreases, wind power, hydropower, nuclear power and solar power generation are popularized and promoted, Used Electric Car have the opportunity to be truly environmentally friendly. 3. Automobile engine noise is the main source of noise during driving. Compared with Fuel Car, Used Car have advantages in this regard. It is basically quiet during driving and operation, and is particularly suitable for driving on urban roads where noise pollution needs to be reduced. Used Electric Car do not produce exhaust gas during use, and there is no problem of air pollution. 4. The cost of using Used Car is lower than that of traditional Fuel Car, especially for those who have charging conditions at home. Both the daily use cost and maintenance cost are lower than those of traditional Fuel Car. 5. Electrification is a major trend in the development of the auto
