The invention discloses a discharging vehicle and a vehicle charging system. The discharging vehicle comprises a discharging control device, a first power battery, a motor and a motor control circuit;a first pole and a second pole of the first power battery are respectively connected with a first input end and a second input end of the motor control circuit; three output ends of the motor controlcircuit are respectively connected with a three-phase winding inductor of the motor; a neutral line of the motor and the second pole of the first power battery are respectively connected to a first pole and a second pole of a second power battery of the charging vehicle through a charging connection device outside the discharging vehicle; and the discharge control device realizes direct-current step-down charging of the second power battery by the first power battery through the motor control circuit. According to the discharging vehicle, direct-current voltage step-down charging of the charging vehicle can be achieved through the motor control circuit and the motor winding of the discharging vehicle, and the structure needed by charging is small in size, light in weight and low in cost.

    本发明公开了一种放电车辆和车辆充电系统,其中,放电车辆包括放电控制装置、第一动力电池、电机和电机控制电路,第一动力电池的第一极、第二极分别与电机控制电路的第一输入端、第二输入端相连,电机控制电路的三个输出端分别与电机的三相绕组电感相连,电机的中性线和第一动力电池的第二极用于通过放电车辆外部的充电连接装置分别连接至充电车辆的第二动力电池的第一极和第二极;放电控制装置通过电机控制电路实现第一动力电池对第二动力电池的直流降压充电。该放电车辆,利用自身的电机控制电路和电机绕组,即可实现对充电车辆的直流降压充电,实现充电所需的结构体积小,重量轻,且成本低。
