The invention discloses a power mutual-aid direct-current charging system and a control method, and the system comprises at least two direct-current chargers, each direct-current charger comprises at least two direct-current output ends, every two adjacent direct-current output ends are connected through a relay K1, and the direct-current outputs of every two adjacent direct-current chargers are connected through a relay K2; the direct-current output of the last direct-current charger is connected to the direct-current output of the first direct-current charger, so that the direct-current outputs of all the direct-current chargers are connected to form a loop; autonomous power allocation can be carried out between different direct current outputs of the same direct current charger and between direct current outputs of adjacent direct current chargers, so that power dynamic adjustment of the direct current output ends of the direct current chargers is realized. The system is simple in structure, and large-scale deployment can be realized; the power of the direct-current chargers can be mutually supplemented so as to meet different charging requirements.
本发明公开了一种功率互济直流充电系统及控制方法,包括:至少两个直流充电机,每一个直流充电机包括至少两个直流输出端,相邻两个直流输出端之间通过继电器K1连接,相邻两个直流充电机的直流输出之间通过继电器K2连接,最后一个直流充电机的直流输出连接至第一个直流充电机的直流输出,使得所有直流充电机的直流输出连接成环路;同一个直流充电机的不同直流输出之间,以及相邻直流充电机的直流输出之间,均能够进行自主功率调配,以实现直流充电机的直流输出端功率动态调整。本发明系统结构简单,能够实现规模化部署;各个直流充电机之间能够实现功率互济,以适应不同的充电需求。
