The embodiment of the invention provides a power supply system and an electric vehicle. The power supply system comprises a first battery pack, a first battery management module, a first switch and a second switch, the first end of the second switch is connected with the output end of the DC/DC converter, the second end of the second switch is connected with the anode of the first battery pack and the first end of the first switch, the second end of the first switch is connected with the anode of the first load, and the cathode of the first battery pack is connected with the cathode of the first load; and under the condition that the output of the DC/DC converter is detected to be abnormal, the first battery management module controls the second switch to be switched from the on state to the off state, controls the first switch to be in the on state, and controls the first battery pack to be switched from the charging state to the discharging state. According to the embodiment of the invention, the first load can be ensured to work normally when the output of the DC/DC converter is abnormal.

    本申请实施例提供一种电源系统及电动汽车,该电源系统包括第一电池组、第一电池管理模块、第一开关和第二开关;第二开关的第一端连接DC/DC转换器的输出端,第二开关的第二端连接第一电池组的正极和第一开关的第一端,第一开关的第二端连接第一负载的正极,第一电池组的负极连接第一负载的负极;在检测到DC/DC转换器的输出异常的情况下,第一电池管理模块控制第二开关从导通状态切换为断开状态,控制第一开关处于导通状态,控制第一电池组从充电状态切换为放电状态。本申请实施例可以在DC/DC转换器输出异常时也能保证第一负载能够正常工作。
