Where Does the Electricity in the Car Come From?

[StMason]

The electricity in a car comes from the car's battery and the car's alternator. Below is an introduction to the function and working principle of the car battery: Function: The car battery primarily serves the function of storing electrical energy. The alternator generates electricity for the car's use, and any excess electricity flows into the battery for storage. When the vehicle is turned off, some electronic components rely on the battery for power. The car's engine requires gasoline to operate, as gasoline is the fuel for the engine, and the alternator itself does not consume gasoline. Working Principle: The working principle of the battery is to convert chemical energy into electrical energy.
