The present invention provides a power matching method of a matrix power distribution charging system. The charging system comprises at least two direct current modules and several power distribution units (PDUs). The direct current modules and the PDUs are separately connected to a system control unit, and commands are delivered to the direct current modules by using the system control unit, such that the direct current modules output different particular voltage values. The system control unit compares a front-end voltage of each switch apparatus with the particular voltage value outputted by each direct current module to determine a corresponding relationship. The system control unit performs logic calculation according to an actual parking stall power demand, and delivers a control signal to perform opening and closing operations on multiple switch apparatuses of the PDU, thereby implementing a particular direct current module output combination, and achieving an objective that the PDU correctly outputs a particular power. By using existing system resources, each switch apparatus of the PDU automatically matches respective direct current module, and it is unnecessary to use other resources to implement the matching operation. |
