Do you know how to maintain lithium batteries for electric vehicles

1. Do not store at a loss of electricity: the state of loss of electricity means that the battery 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 drops by 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, and try to beware of instantaneous high current discharge. 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. Generally, the battery is charged at night, and the average charging time is about 8 hours. If it is a shallow discharge (the mileage is short after charging), the battery will soon overflow, and continuous charging will cause overcharging, which will cause the battery to heat up and reduce the battery life. Therefore, it is best to charge the battery once when the depth of discharge is 60% 70% (two bars down), and it can be converted into riding mileage in actual use. Charge it according to the actual situation and beware of harmful charging. 5. Beware of high temperature exposure. An environment with too high temperature will increase the internal pressure of the battery and the battery pressure limiting valve will be forced to open automatically. The straight result is the water loss of the new battery. Excessive battery loss will inevitably lead to a decrease in battery activity, accelerate the softening of the plate, and charge. When the shell heats up, the shell bulges, deforms and other fatal injuries. 6. Charge the battery in winter, keep it indoors, and warm up the battery for two hours before charging. The battery of the battery car battery will not run far away as Vietnam has been used slowly. This is normal, especially in cold weather. The battery generally needs to be fully charged once at most 70-80% of the electricity consumption. The so-called full charge is After changing the lamp for about 2 hours, it can ensure that the battery is fully charged 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. The battery’s capacity is often used when it’s empty or when it’s charged without changing the light. It’s necessary to recharge it once if you don’t need it for about 20 days. The master upstairs said that it’s impossible for you to fill it with distilled water, because The lithium battery of an electric vehicle is a fully closed and maintenance-free battery. Normally, it can be used for about 2 years, but it depends on the mileage you need to run every day. 1. Charger maintenance When it comes to charging electric vehicles, the first thing to use is electric vehicle chargers. Protecting the charger is a very important step. At present, 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 vehicle charger will cause the internal electrical potentiometer to drift after a long period of vibration, making the charging parameters become abnormal, the battery life 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. 2. Charge every day. Many people have a certain misunderstanding about how long to charge an electric vehicle, thinking that they should wait until the lithium battery of an electric vehicle is completely used up before charging. In fact, this is also wrong. The current lithium batteries for electric vehicles generally use lead-acid batteries, and their memory capacity is not very strong, but often a discharged battery will have a greater impact on the battery. Daily charging makes the battery power in a shallow cycle state to make the life of the lithium battery of electric vehicles longer. 3. Regular deep discharge As mentioned earlier, electric vehicles 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 detailed method is to charge the electric bike until it prompts undervoltage. Note that after riding to undervoltage, the electric bike will recover part of its power after a period of time. Do not ride again at this time, otherwise the battery will be very damaged. How to extend the life of electric vehicle lithium battery? 4. A good habit of riding a bicycle. I mentioned the precautions for charging electric vehicles. Now I will talk about the issues to be aware of when riding a bicycle. When riding a bicycle, you must master a principle, start slowly and stop slowly. In detail, the flow should be slow when starting, and try to beware of sudden braking. Because the electric load is the largest when the electric vehicle starts and brakes suddenly, the often unstable current will reduce the life of the lithium battery of the electric vehicle. 5. Parking environment In general, the lithium battery of electric vehicles is included with the car. The quality of the parking environment also has a certain impact on the battery. The parking environment of electric vehicles should be kept ventilated and dry as much as possible. Because the humid environment will cause the leakage of the lithium battery of the electric vehicle, so as to shorten the battery life. 6. Pay attention to frequent maintenance. Many electric vehicle dealers will provide free after-sales maintenance services, which can be said to be an opportunity for regular maintenance. For example, the lack of battery electrolyzed water can only be discovered during maintenance. Measures such as timely water replenishment are also very important for battery maintenance.
