Today's automobile is a complex mechanical and electrical product, and most of its functions are controlled by electricity, such as engine electronic control system, automatic transmission electronic control system, body electronic control system, braking and steering electronic control system, lighting system, and so on. Some people may wonder: there is no external power source on the car. Where does all the electricity come from? How does it feel like electricity is inexhaustible? Although the car has a battery, but it should store a limited amount of electricity, when it is exhausted, and how to replenish it?
Although the car does not have an external power supply, the car itself has a power supply, which can realize self-electricity. This is the car charging system. There are two power sources in the car, one is the battery, can store a certain amount of electric energy, before the engine did not start, all the electric energy on the car is provided by it, such as starting the engine, listening to music, car anti-theft system, etc.; The other is the generator, which is the main power supply on the car. When the engine is running normally, all the electric energy on the car is provided by the generator. The excess electric energy will be stored in the battery. Working together, they make up the car's power system.
