Abstract: Disclosed is a method for controlling charging of charging devices, which includes: serially connecting the plurality of charging devices into a charging queue and detecting parameters of at least some charging devices in the charging queue; determining a relative location of each charging device in the queue; and starting or stopping charging of each charging device according to the parameters and the relative location of the charging device. Also disclosed is a charging control device. Accordingly, the connection of any number of charging devices into the queue at any time without exceeding the power load by controlling start and stop of charging each charging device. Overcharging phenomenon can be prevented by stopping charging in a timely manner, saving electric energy. Also, the charging device at the queue tail can be charged preferentially, making it convenient for picking up a trolley from the queue tail, and better satisfying operation needs.
