How to maintain electric vehicle batteries?

During the use of electric vehicles, the charging time should be accurately grasped according to the actual situation, and the frequency of charging should be grasped by referring to the usual frequency of use and mileage. During normal driving, if the electricity meter indicates red and yellow lights are on, it should be charged; if only the red light is left on, stop running and charge as soon as possible, otherwise the battery will be over-discharged and its life will be seriously shortened. After fully charged, the running time is short, and the charging time should not be too long, otherwise it will cause overcharging and make the battery heat up. Overcharge, overdischarge and undercharge will shorten the battery life. In general, the average charging time of the battery is about 10 hours. If the battery temperature exceeds 65°C during the charging process, stop charging. 2. When the battery is stored, it is strictly prohibited to be in a state of loss of power. When the battery is stored in a state of depletion, sulfation is prone to occur. Lead sulfate crystals adhere to the electrode plate, which will block the ion channel, resulting in insufficient charging and decreased battery capacity. The longer the idle time in the power-deficient state, the more severe the battery damage. Therefore, when the battery is not in use, it should be recharged once a month to better maintain the battery's health. 3. Try to prevent slamming and accelerating. During use, if the continued mileage of the electric vehicle 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 a problem. When the electric vehicle starts, carries people, or goes uphill, try to prevent it from slamming and accelerating to form an instantaneous large current discharge. High-current discharge can easily lead to the appearance of lead sulfate crystals, which will damage the physical properties of the battery plates.
