Can a Car Charge the Battery When Idling Without Moving? A car can charge the battery when idling without moving, but the prerequisite is to ensure that all electrical appliances except the engine operation are turned off. Firstly, as long as the generator is working, it can charge the battery, and the power source of the generator comes from the engine. After the car starts, the engine begins to work, and it transmits power to the generator through the belt, so the battery starts to be charged. It should be noted that the charging efficiency is different in the idling state and the driving state. When the vehicle is moving, because you need to step on the accelerator, and as soon as you step on the accelerator, the engine speed will increase, and the generator will get more power accordingly, so the generator's power generation will increase, and the battery charging will also be more.
