The invention provides a dynamic adjusting controlling method of charging power. The method comprises the following steps: acquiring real-time charging data; determining load rate based on the real-time charging data; comparing the load rate with at least one preset threshold; in case that the load rate is beyond the at least one preset threshold, determining de-rating charging devices based on the real-time charging data; arranging the de-rating charging devices to form a first sequence; and de-rating the output power based on the first sequence. According to the method, the overall load of acharging system is dynamically flexibly adjusted, so that frequent starting and stopping control which leads to high impact on the system and a circuit can be avoided. Additionally, the invention also provides another dynamic adjusting controlling method of the charging power, computer equipment for performing the abovementioned two dynamic adjusting controlling methods of the charging power anda storable medium.
