Where Does the Car Battery Get Its Electricity From?

[MatteoDella]

Car batteries get their electricity from the alternator. Additional information: Detailed explanations are as follows: 1. The engine runs by burning fuel, and its operation drives the alternator to generate electricity. Part of this generated electricity is stored in the battery, whose function is to store and supplement electrical power. 2. The car engine is the device that provides power to the vehicle, serving as the heart of the car. It determines the vehicle's power, fuel efficiency, stability, and environmental performance. Depending on the power source, car engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, hybrids, etc. 3. Common gasoline and diesel engines are both reciprocating piston-type internal combustion engines that convert the chemical energy of fuel into the mechanical energy of piston motion to output power. Gasoline engines have higher rotational speeds, lighter weight, lower noise levels, easier starting, and lower manufacturing costs. Diesel engines have higher compression ratios, greater thermal efficiency, and better fuel economy and emission performance compared to gasoline engines.
