A system, method and device for charging the same vehicle through two direct current charging piles are characterized in that the system comprises a first charging pile, a second charging pile, a vehicle socket and a relay; the first charging pile and the second charging pile are connected through an internal CAN bus, the two vehicle sockets are arranged on a vehicle, each charging pile corresponds to one vehicle socket, and the relay is arranged between two BMS interfaces of the vehicle sockets. The mode that two independent small-power chargers charge two vehicles respectively is changed into the mode that two small-power chargers charge the same vehicle at the same time, the vehicle charging power is improved, meanwhile, hardware transformation does not need to be conducted on the power part of equipment, the cost is saved, and the vehicle charging efficiency is improved. And meanwhile, the problem that an original single low-power charger charges the vehicle slowly is solved.
一种两台直流充电桩给同一车辆充电的系统及方法及设备,其特征在于,包括第一充电桩、第二充电桩、车辆插座和继电器;第一充电桩和第二充电桩通过内部CAN总线连接,两个车辆插座设置在车辆上,每个充电桩对应一个车辆插座,继电器设置在车辆插座的两个BMS接口之间。本发明通过将两台独立的小功率充电机各自给两辆车辆充电方式,改为两台桩同时给同一辆车充电的方式,提高了车辆充电功率的同时,不需要对设备的功率部分进行硬件改造,节省了该造成成本,同时解决了原有单台小功率充电机给车辆充电慢的问题。
