The invention discloses an electric vehicle power management system and method, electronic equipment and a storage medium. The system is characterized in that a whole vehicle domain controller independently controls a high-voltage power supply by controlling a high-voltage control unit; the whole vehicle domain controller realizes power supply control on low-voltage electric appliances by controlling the low-voltage control unit; the remote intelligent control end, the Bluetooth control module and the vehicle body controller are connected with the whole vehicle domain controller, and non-inductive power-on and power-off control over the vehicle, power-off control over user action timeout and power-off control under the vehicle fault state are achieved. Unified distribution of high-voltage and low-voltage power supplies of the whole vehicle is realized, branch power switches are actually controlled based on user demands, and optimal energy consumption of the whole vehicle system is ensured; user behaviors are monitored, a cut-off path is provided when the user forgets to lock the vehicle in a power-off mode, and the problems of storage battery power consumption and property safety caused by the fact that the vehicle is powered on and not locked are solved; and the problems of brake assisting power and steering assisting power failure and the like caused by failure of a single controller in the running process of the vehicle are solved.

    本发明公开了一种电动汽车整车电源管理系统、方法、电子设备及存储介质。系统包括:整车域控制器通过控制高压控制单元独立控制高压电源;整车域控制器通过控制低压控制单元实现对低压用电器的供电控制;远程智能控制端、蓝牙控制模块和车身控制器分别与整车域控制器连接,实现车辆无感上下电控制、用户动作超时的下电控制和车辆故障状态下的下电控制。本发明实现整车高低压电源统一分配,基于用户需求实际控制支路电源开关,保证整车系统能耗最优;对用户行为进行监控,在用户遗忘下电锁车工况,提供一种切断路径,避免车辆上电未锁车带来的蓄电池耗电及财产安全问题;避免车辆运行过程中因单个控制器失效引起的制动助力及转向助力失效等问题。
