How did the car battery come from?

The electricity of the car battery comes from the car generator. The automobile engine is equipped with an automobile generator, and the kinetic energy of the engine is transferred to the generator through the generator belt, converted into electric energy, and then stored in the automobile battery. Generally, the on-board battery voltage of a gasoline engine is 12V, so the on-board voltage is 12V.

Details are as follows:

1. The engine runs on oil. The operation of the engine makes the generator generate electricity, and part of the generated electricity is stored in the storage battery, which plays the role of energy storage and power supply.

2. The automobile engine is the device that provides power for the automobile, and it is the heart of the automobile, which determines the power, economy, stability and environmental protection of the automobile. According to different power sources, automobile engines can be divided into diesel engine, gasoline engine, electric vehicle motor and hybrid power.

3. Common gasoline engines and diesel engines belong to reciprocating piston internal combustion engines, which convert the chemical energy of fuel into mechanical energy of piston movement and output power to the outside world. Gasoline engine has the advantages of high speed, light weight, low noise, easy start and low manufacturing cost. Diesel engine has high compression ratio and high thermal efficiency, and has better economic performance and emission performance than gasoline engine. Million car purchase subsidy
