What is the reason for the self-discharge of the battery

The reasons for the self-discharging of the battery include that the electrolyte is impure, the electrolyte contains a lot of metal impurities, forms a closed circuit with the positive and negative electrodes, and the top of the battery is not clean, resulting in a short circuit between the positive and negative terminals.

　　

At present, most of the batteries used in electric vehicles are lead-acid batteries, because lead-acid batteries are relatively cost-effective and low in cost, and the batteries can be recharged and used repeatedly. Generally, the charging of the battery is carried out at night, and the average charging time is about 8 hours. The specific charging time needs to be carried out according to the actual use of the electric vehicle to avoid harmful charging. When using electric vehicles, it is necessary to correctly grasp the charging time of the battery, and refer to the battery capacity provided by the battery manufacturer.
