Can a Vehicle Charge Its Battery When Idling Without Moving?
1 Answers
Vehicle idling without moving can charge the battery. However, it is necessary to ensure that all electrical appliances (except for the engine operation) are turned off, so that the battery can be charged. Reasons why it can charge: When the car battery is charging, it can be charged by the rotation of the engine. As the engine runs, the belt drives the generator to produce a charging current. The current passes through the vehicle's voltage regulator transformer, and part of the filtered current is used for the vehicle's operation, while the excess part is used to charge the onboard battery. Precautions for onboard charging: The USB port inside the car is set up for audio data transmission, and most vehicle ports only have a 5V current, which is insufficient and may damage the charging device if not up to standard; the output current of the car charger should not exceed the maximum rated input power of the phone; after the car is turned off, the car charger must be unplugged. If the car charger is not unplugged, it may damage the battery after the vehicle is turned off.
