Matrix-type flexible charging system, charging control method and device

The invention discloses a matrix type flexible charging system, a charging control method and a device. The system comprises a first preset number of power conversion modules, a second preset number of charging guns, a third preset number of crossover busbars, a primary matrix and a secondary matrix. Wherein the jumper bus is connected to the power conversion module through a controllable switch in the primary matrix, the number of controllable switches in the primary matrix is the product of the first preset number and the third preset number, the crossover bus is connected with the charginggun through the controllable switches in the secondary matrix, and the number of controllable switches in the secondary matrix is the product of the second preset number and the third preset number; By setting controllable switches in the primary matrix and the secondary matrix, the invention can reduce the average switching times and switching time in the process of charging the battery by usingthe corresponding charging
