When the engine is running normally, the car alternator supplies power to all electrical equipment except the starter, while simultaneously charging the battery, ensuring the normal operation of the vehicle's electrical equipment. For example, it provides power to the ignition system, electronic fuel injection system, lights, audio system, air conditioning, electronic control system, etc., and replenishes the power consumed by the in-vehicle electrical appliances when starting or stopping the engine.
