The invention relates to the technical field of charging piles, in particular to an overload protection device and an overload protection method of a charging pile. According to the technical scheme, the system comprises a main controller, an input power supply processing circuit, a plurality of sub-controllers and a plurality of charging output circuits, the input power supply processing circuit is connected with the plurality of charging output circuits, and the main controller is connected with the input power supply processing circuit and the plurality of sub-controllers; a power detection module and a power distribution limiting module are arranged in the main controller, the power detection module obtains the charging power of each charging output circuit, and the power distribution limiting module distributes and limits the charging power of each charging output circuit. The invention has the advantages that the charging states of the multiple charging output circuits are detected through the master controller, when the total output power exceeds the rated power, distribution is carried out according to the charging states of the charging output circuits, and maximization of the charging efficiency of the charging output circuits can be achieved on the premise of overload protection.
