Introduction to the maintenance of electric vehicle batteries

1. Do not store at a loss of electricity: the state of loss of electricity means that the battery of an electric car is not charged in time after use, resulting in insufficient charging and a decrease in battery capacity. The longer the idle time in the power-deficient state, the more serious the battery is damaged. When the battery is not in use, it should be recharged once a month, which can prolong the service life of the battery. 2. It is necessary to check regularly during use. If the continuous mileage of the electric bicycle suddenly drops more than ten kilometers in a short period of time, it is very likely that at least one battery in the battery pack has broken grids, softened plates, and activated plates. Short-circuit phenomena such as material shedding. At this time, you should go to a professional battery repair organization for inspection and repair in time. 3. Do not discharge the electric bicycle with high current. It is best to use the pedals to assist when starting, carrying people, or going uphill to prevent instantaneous high current discharge as much as possible. High-current discharge can easily lead to the crystallization of lead sulfate, thereby damaging the physical properties of the battery plate. 4. Master the charging time. Under normal circumstances, electric vehicle batteries are charged at night, and the average charging time is about 8 hours. If it is shallow discharge (the mileage is short after charging), the battery will be fully charged soon, and overcharge will occur if the battery continues to charge, which will cause the battery to heat up and reduce the battery life. Therefore, it is best to charge an electric vehicle battery at a discharge depth of 60% to 70% (two bars down). It can be converted into a riding mileage in actual use, and necessary recharge according to the actual situation to prevent harmful charging. 5. Prevent high temperature exposure. An excessively high temperature environment will increase the internal pressure of the electric vehicle battery and the battery pressure limiting valve will be forced to open automatically. The direct consequence is the water loss of the newly added battery. Excessive battery loss will inevitably lead to a decrease in battery activity and accelerate the softening of the plate. , When charging, the shell heats up, the shell bulges, deforms, and other fatal injuries. 6. Charge the battery in winter, keep it indoors, and warm the battery of an electric car for two hours before recharging. As the time of use, the battery of electric vehicles will not run far from Vietnam. This is normal, especially in cold weather. Generally, the battery needs to be charged once when 70-80% of the electricity is used. The so-called full charge means waiting. After changing the lamp, it can be charged for about 2 hours to ensure that the battery floats in place and reaches the best mileage. Generally, there is a deep discharge in about two months, that is, it can be recharged with empty to achieve the phenomenon of lead precipitation and improve the battery’s performance. Capacity, the most feared is that electric vehicle batteries are often used when they are empty or the lights are not changed when they are charged. If they are not used for a long time, they must be fully charged once for about 20 days. 7. Parking environment Generally, the battery of an electric car is integrated with the car. The quality of the parking environment also has a certain impact on the battery. The parking environment of electric cars should be kept ventilated and dry as much as possible. Because the humid environment will cause electric vehicle battery leakage, so as to shorten the battery life. 8. Charger maintenance When it comes to charging electric cars, the first thing you use is electric car chargers. Protecting the charger is a very important step. Nowadays, the cost of electric vehicles is relatively low, and the shock-proof performance of the charger is not very good. Many people like to put the charger in the trunk or basket of the electric vehicle. In fact, this behavior is very bad. Because the electric car charger will drift in the internal electrical potentiometer after long-term vibration, making the charging parameters become abnormal, the life of the battery will be shortened when the charging time of such a charger is long. In addition, the charger needs to be charged. Ensure good ventilation to ensure good heat dissipation. 9. Pay attention to frequent maintenance. Many electric car dealers will provide free after-sales maintenance services, which can be overhauled and maintained on time. For example, the battery electrolysis water is insufficient, which can only be discovered during maintenance, and measures such as timely water replenishment are also very important for battery maintenance. 10. Charge every day. Many people have a certain misunderstanding about how long to charge an electric vehicle. They think that they should wait until the electric vehicle battery is completely used up before charging. In fact, this is also wrong. The current electric vehicle batteries generally use lead-acid batteries, which have not very strong memory capabilities, but often discharged batteries will have a greater impact on the battery. Daily charging makes the battery power in a shallow cycle state to make the battery life of electric vehicles longer. 11. Regular deep discharge As mentioned earlier, electric cars should be charged every day as much as possible. However, reasonable regular deep discharge is also beneficial for activating the battery. Generally one to two months deep discharge is the most reasonable. The specific method is to charge the electric vehicle when it is under-voltage indicated. Note that after riding to undervoltage, the electric vehicle will recover part of its power after a period of time. Don't ride it again at this time, otherwise the battery will be very damaged. 12. Good riding habits. I mentioned the precautions for charging electric vehicles. Now let’s talk about the issues that should be paid attention to when riding a bicycle. There is a principle to be mastered when riding a bicycle, start slowly and stop slowly. Specifically, the flow should be slow when starting to prevent sudden braking as much as possible. Because the electric load is the largest when the electric vehicle starts and brakes suddenly, frequent unstable current will reduce the life of the electric vehicle battery.
