Compared with the prior art, the beneficial effects of the utility model are that: the charging pile cluster adopts a mode of one host and multiple terminals, and is connected with a charging station monitoring management system (background) through charging pile cluster monitoring to form a charging pile cluster controller self-adaptive power distribution network. The equipment utilization rate of the charging station is guaranteed to be maintained at a high level through automatic power distribution, and the charging station is adaptive to vehicle models with different powers, such as a trolley, a bus and the like. The total load power of the charging station can be dynamically adjusted in real time; the equipment utilization rate of the charging station can be improved, and the phenomenon that part of charging piles are stopped to be used in the electricity utilization peak period is avoided; the load utilization rate of the charging station can be improved, and the residual power of the battery pack when the battery pack is nearly full can be effectively utilized.
