The invention relates to a power battery pack charging and power supply system and method and a vehicle. The power battery pack charging and power supply system (100) comprises: a power battery pack comprising a first battery module (11) and a second battery module (12) which are connected in series; a motor controller (20); the motor (30) is connected with the motor controller; a first node (A) between the first battery module and the second battery module is connected with a neutral point (B) of the motor through the first switch (40); and the master controller is used for controlling the first switch to be switched on and controlling the motor controller under the condition that only one of the first battery module and the second battery module fails and a charging instruction is received, so that the battery module which does not fail is charged through the motor controller and the motor. When part of the battery modules fail, the motor controller and the motor can be utilized to form a loop, and only part of the battery modules which do not fail are charged, so that the endurance problem of the vehicle is solved.

    本公开涉及一种动力电池包充电供电系统、方法和车辆。动力电池包充电供电系统(100)包括:动力电池包,包括串联连接的第一电池模组(11)和第二电池模组(12);电机控制器(20);电机(30),与电机控制器连接;第一开关(40),第一电池模组和第二电池模组之间的第一节点(A)与电机的中性点(B)通过第一开关(40)连接;总控制器,用于在第一电池模组和第二电池模组中仅有一者失效,且接收到充电指令的情况下,控制第一开关闭合,并控制电机控制器,以通过电机控制器和电机对未失效的电池模组进行充电。当有部分电池模组失效时,能够利用电机控制器和电机形成回路,仅对未失效的部分电池模组进行充电,从而解决车辆的续航问题。
