Does the car charge when idling after starting?

[Emilia]

The car can charge when idling after starting, but the prerequisite is to ensure that all electrical appliances except the engine operation are turned off. First, as long as the generator is working, it can charge the battery. The power source of the generator comes from the engine. After the car starts, the engine begins to work, and the engine transmits power to the generator through the belt, thus starting to charge the battery. It should be noted that the charging efficiency is different between idling and driving states. When the vehicle is moving, because you need to step on the accelerator, as soon as you step on the accelerator, the engine speed will increase, and accordingly, the generator will receive more power, so the generator's output will increase, and the charging amount to the battery will also be more. If the engine is idling, the generator speed is slower, and the output power will be very limited.
