The invention relates to the technical field of power supply control, and particularly discloses a vehicle electrical architecture, an electric vehicle and a power supply control method. The vehicle electrical architecture comprises a plurality of battery cells, positive electrode control modules and negative electrode control modules, wherein the positive electrode control modules and the negative electrode control modules correspond to the battery cells in number; the plurality of battery cells are connected in series, the positive pole of each battery cell is connected with the first end of the corresponding positive pole control module, the second end of the positive pole control module is connected with the positive pole of the low-voltage load, the negative pole of each battery cell is connected with the first end of the corresponding negative pole control module, and the second end of the negative pole control module is connected with the negative pole of the low-voltage load; and the positive electrode control module and the negative electrode control module are used for conducting the positive electrode control module and the negative electrode control module corresponding to the battery cells to continuously supply power to the low-voltage load according to the voltage amplitude of each battery cell. A certain number of battery cells are selected to supply power to the low-voltage load all the time, the situation that the low-voltage load cannot be awakened due to long-time high-voltage state is avoided, and normal operation of the vehicle is ensured.

    本发明涉及供电控制技术领域,具体公开了一种车辆电气架构、电动汽车及供电控制方法。该车辆电气架构包括:多个电池电芯、与电池电芯数量对应的正极控制模块以及负极控制模块;多个电池电芯之间串联连接,各电池电芯的正极与对应的正极控制模块的第一端连接,正极控制模块的第二端连接低压负载的正极,各电池电芯的负极与对应的负极控制模块的第一端连接,负极控制模块的第二端连接低压负载的负极;正极控制模块与负极控制模块,用于根据各电池电芯的电压幅值,导通电池电芯对应的正极控制模块以及负极控制模块持续为低压负载供电。通过选取一定数量的电池电芯始终为低压负载供电,避免因长时间处于高压状态无法唤醒低压负载,确保车辆正常运行。
