Charging pile charging control method, system and device and storage medium

The invention relates to the technical field of charging, in particular to a charging control method, system and device of a charging pile and a storage medium, the charging pile comprises M rows and N columns of relays, N charging terminals connected with the N columns of relays in a one-to-one correspondence manner, and M power modules connected with the M rows of relays in a one-to-one correspondence manner; the method comprises the steps of obtaining charging duration of a charging terminal; after it is determined that the charging duration of the charging terminal reaches a set duration threshold value, the required power of the charging terminal and the module power of a power module for supplying power to the charging terminal are obtained; adjusting the number of power modules for supplying power to the charging terminal in real time based on the deviation between the module power and the required power, so as to enable the deviation between the module power and the required power to be within a set p
