What is a battery and what is its function? What is the relationship between batteries and batteries?

Vehicle battery, also known as storage battery, is a device that converts chemical energy into electrical energy, and its function is to provide electrical energy for the engine.

The functions of the battery can be summarized as follows:

1. When the engine starts, it supplies power for the starting system, ignition system, electronic fuel injection system and other electrical equipment of the automobile;

2. When the engine stops running or at low idle speed, power is supplied to the automobile electrical equipment;

3. When the power demand exceeds the power supply capacity of the generator, the battery will also participate in power supply;

4. The storage battery plays the role of voltage regulator in the vehicle electrical system, which can relieve the surge voltage in the point system and protect the electronic equipment on the vehicle;

5. When the generator works normally, the storage battery stores the surplus electric energy generated by the generator.
