[0002] Car batteries, also called storage batteries, are a type of battery that works by converting chemical energy into electrical energy. Usually, when people refer to batteries, they are referring to lead-acid batteries, which are batteries that are mainly made of lead and its oxides, and whose electrolyte is sulfuric acid solution.

[0003] Existing car batteries are not completely powered off after the vehicle is turned off. In many cases, after the driver turns off the engine and gets off the vehicle, he often forgets to turn off the electrical devices in the vehicle, such as the lighting system. At the same time, the keyless entry system of the vehicle will also consume battery power when the vehicle is idle. If the parking time is long, this will cause the relevant electrical devices to work for a long time. The power supply for the electrical devices when working comes from the on-board battery. If the battery energy is not replenished, the battery will be seriously depleted.
