The invention discloses a multi-plug DC charging pile system, the number of whose charging modules can reach more than 6, while the number of plugs is only half of the number of charging modules. Each charging module can be switched to any plug. At the same time, the economy, practicability and stability of the product are improved. The multi-plug DC charging pile system includes: six DC charging modules, three plugs, a main control board, a switching control board and sixteen DC contactors. The main control board controls the output of six DC charging modules through CAN. The main control board is connected with the switching control board. The main control board is connected with three plugs through CAN. The sixteen DC contactors are connected with one of three plugs respectively. The switching control board controls the on-off of sixteen DC contactors to control the DC charging power obtained by three plugs. The present invention also provides a charging power distribution method of this multi-plug DC charging pile system.
