Can the car battery be charged at idle speed? The car battery can be charged at idle speed, but the charging effect is not good. After the engine starts, the electricity generated by the alternator is mainly used to power the vehicle itself, leaving little remaining current. It is only when the engine speed exceeds 2000 RPM that the current becomes sufficient. Therefore, it is not recommended to charge the battery at idle speed. The car battery is charged by the alternator while the vehicle is running, so there is rarely a need for dedicated charging. However, if the battery is severely drained due to an unexpected situation, it should be charged promptly and not solely rely on the car's own charging system. Generally, after the car engine is turned off, the switches of related equipment inside the car should be turned off in time to prevent severe battery drain.
