The role of the alternator is to provide continual charge to the battery whilst engine is running. This supply of power prevents the battery from discharge, and provides the requested power to the car's electrical devices. The alternator is connected and powered by the crankshaft through a drive belt. When the engine is running, the drive belt rotates the alternator, which converts the kinetic energy into electrical current. The general principle is to transform the movement initiated by the flywheel into electricity.
