The invention discloses a double-loop power supply system, and a power supply control method and a device of an electric automobile. The double-loop power supply system comprises a power battery usedfor providing a working power supply for the electric automobile; a first power supply conversion module which is connected with the power battery and is used for converting a power supply provided bythe power battery into alternating current required by the electric automobile; and a second power supply conversion module which is connected with the power battery and is used for executing the function of the first power supply conversion module to convert the power supply provided by the power battery into the alternating current required by the electric automobile under the condition that the first power supply conversion module fails. The technical problem that in the related art, when an oil pump controller of the electric automobile breaks down, continuous working of an oil pump is impossible to realize, and traffic accidents are likely to be caused is solved.

    本发明公开了一种双回路供电系统、电动汽车的供电控制方法及装置。其中,该双回路供电系统包括:动力电池,用于为电动汽车提供工作电源;第一电源转换模块,与动力电池连接,用于将动力电池提供的电源转换为电动汽车所需的交流电;第二电源转换模块,与动力电池连接,用于在第一电源转换模块发生故障的情况下,执行第一电源转换模块的功能将动力电池提供的电源转换为电动汽车所需的交流电。本发明解决了相关技术中电动汽车的油泵控制器出现故障时,油泵无法连续工作,容易造成交通事故的技术问题。
