The Role Of Car Batteries

The battery can provide electric energy for the vehicle and can store electric energy. Its main functions include: when the engine is started or running at low speed, because the car generator does not generate electricity or the voltage is very low, all the electronic systems in the car are provided by the battery. When the engine is running normally, the generator supplies power to the electrical equipment and simultaneously charges the battery. At the same time, the battery is also a large-capacity capacitor, which can absorb the instantaneous high voltage generated in the circuit in the car, thereby protecting the electrical equipment in the car.
