The embodiment of the invention discloses an electric vehicle double-battery power supply system and a control method thereof. The double-battery power supply system comprises a first battery assemblyand a second battery assembly which are electrically connected, and the first battery assembly comprises a first battery management system and a first battery which are electrically connected; the second battery assembly comprises a second battery management system and a second battery which are electrically connected; the first battery management system is used for collecting electrical parameters of the first battery; and the second battery management system is used for acquiring electrical parameters of the second battery and switching to a single-battery power supply mode or a double-battery power supply mode according to the electrical parameters of the first battery and the second battery. According to the embodiment of the invention, the maximum power supply power and system powersupply backup can be provided for the whole vehicle, the driving safety and stability can be improved while the endurance mileage is increased, and the riding experience of a user is improved. In addition, the double-battery power supply system reduces the size of a single battery assembly and is convenient to carry.

    本发明实施例公开了一种电动车双电池供电系统及其控制方法,该双电池供电系统包括:电连接的第一电池组件和第二电池组件,第一电池组件包括电连接的第一电池管理系统和第一电池,第二电池组件包括电连接的第二电池管理系统和第二电池;第一电池管理系统用于采集第一电池的电气参数;第二电池管理系统用于采集第二电池的电气参数,并根据第一电池和第二电池的电气参数,切换为单电池供电模式或者双电池供电模式。本发明实施例可对整车提供最大的电源供电功率与系统供电的备份,提高续航里程的同时可提高行车的安全性和稳定性,提高用户的骑行体验。此外,双电池供电系统减小了单个电池组件的体积,携带方便。
