The embodiment of the invention provides a switching circuit and an electric vehicle. The switching circuit comprises a first battery, a first DC/DC converter, a second DC/DC converter and a load. The first output end of the first battery is connected with the first end of the first DC/DC converter, the second end of the first DC/DC converter is connected with the power supply end of the load, the second output end of the first battery is connected with the first end of the second DC/DC converter, and the second end of the second DC/DC converter is connected with the power supply end of the load; an output voltage of the first DC/DC converter and an output voltage of the second DC/DC converter are controlled such that the first DC/DC converter and the second DC/DC converter alternately output or simultaneously output. According to the embodiment of the invention, the fault occurrence rate can be reduced when the two DC/DC converters work in parallel.

    本申请实施例提供一种切换电路及电动汽车,该切换电路包括第一电池、第一DC/DC转换器、第二DC/DC转换器和负载;第一电池的第一输出端连接第一DC/DC转换器的第一端,第一DC/DC转换器的第二端连接负载的供电端,第一电池的第二输出端连接第二DC/DC转换器的第一端,第二DC/DC转换器的第二端连接负载的供电端;控制第一DC/DC转换器的输出电压和第二DC/DC转换器的输出电压,以使第一DC/DC转换器和第二DC/DC转换器交替输出或同时输出。本申请实施例可以在两个DC/DC转换器并联工作时降低故障发生率。
