Please refer to FIG. 1. FIG. 1 is a schematic structural diagram of a power station configuration system for a charging station according to the present invention. The system includes a manager 1 and N module controllers 1 corresponding to N charging piles in a charging station. N charging replacement module groups 3 corresponding to N module controllers 2; each charging module group 3 includes a plurality of charging modules and a plurality of reserved positions, and N is an integer greater than 1, wherein :

Each charging module group 3 includes a plurality of replaceable charging modules and a plurality of reserved positions, and the replaceable charging module has a standardized design interface. The charging module here can supply power to the electric vehicle connected to the charging pile; the reserved position can install the charging module to increase the charging power, and the increased charging power is equal to the sum of the charging powers of the increased charging module. It can be seen that the current number of charging modules and the number of reserved positions jointly determine the maximum power supply capacity of the charging module group 3.

The current power supply capability of the charging module group 3 is determined by the corresponding module controller 2.

Then, the power of the single charging pile in the A charging station is adjusted to 30 kW, and the redundant charging module of the A charging station is transferred to the B charging station, so that the power of the single charging pile of the B charging station is adjusted to 60 kW. . By analogy, according to the design principle, the power is dynamically adjusted between a plurality of charging stations, especially during holidays, and the demand power of the charging station on the expressway is increased, so that the charging module can be deployed from other charging stations that require reduced power. Optimize resource allocation.
