Provided is a charging control method, applied to a charging pile. The method includes: acquiring a charging current, a terminal voltage of charging loop, and a voltage of one or more batteries by means of a battery management system when the charging pile charges the one or more batteries; obtaining a connection cable resistance value and an internal resistance of the one or more batteries according to the charging current, the terminal voltage of charging loop, and the voltage of one or more batteries; determining, according to the connection cable resistance value and the internal resistance of the one or more batteries, whether early warning is needed; and when early warning is needed, reducing a duty cycle of a first signal, and outputting the first signal to a charging controller. The charging pile can perform information interaction with a battery pack, to perform safe charging control according to charging parameters.
