Car Battery Function
May 26, 2020
It is a device that converts chemical energy into electrical energy. It belongs to a DC power supply. The functions of a car battery are:
(1) When starting the engine, provide a strong starting current (about 10A) to the starter.
(2) When the generator is overloaded, it can assist the generator to supply power to the electrical equipment.
(3) When the engine is idling, supply power to the electrical equipment.
(4) The battery is also a large-capacity capacitor, which can protect the car's electrical appliances.
(5) When the generator terminal voltage is higher than the electromotive force of the lead battery, a part of the electrical energy is converted into chemical energy for storage, that is, charging.
