Why do the car have a battery? What is the role?

The battery is most important to start the automotive engine and power supply to the internal electric control system to ensure the normal operation of the vehicle. When it is charged by the generator on the engine without power, power is supplied to the electrical control system when the engine is not operating. (1) When starting the engine, provide a powerful starting current (generally up to 200-600A) to the starter. (2) When the generator is overloaded, the generator can be assisted to power the power supply. (3) Powering the power equipment when the engine is idling. (4) When the generator end voltage is higher than the electric potential of the lead battery, a part of the electrical energy transition is chemically stored, that is, charging. (5) The battery is still a large capacity capacitor, which can protect the electric appliance of the car.
