The invention provides a vehicle electric quantity management method and system, electronic equipment and a storage medium. The method comprises the following steps: acquiring current electric quantity of a vehicle as first electric quantity and historical electric quantity of the vehicle before a preset time period; if the first electric quantity is smaller than the historical electric quantity and smaller than or equal to a preset threshold value, the reserved power generation power of a range extender of the vehicle is obtained to adjust the discharging power of a battery so as to control the range extender to release the reserved power generation power to charge the vehicle; after the vehicle is charged for a preset time period, acquiring the current electric quantity of the vehicle as second electric quantity; and if the second electric quantity is smaller than or equal to the first electric quantity, heat management power output by the heat management module and driving power output by the driving module are limited according to a preset whole vehicle energy management rule, and the range extender is controlled to output with target compensation power so as to release the compensation power to charge the vehicle. The vehicle battery pressure is effectively relieved, and the power battery electric quantity cannot be continuously reduced.

    本申请提供了一种车辆电量管理方法、系统、电子设备及存储介质,包括获取车辆的当前电量为第一电量以及车辆在预设时间段之前的历史电量;若第一电量小于历史电量且第一电量小于等于预设阈值,则获取车辆的增程器的预留发电功率来调整电池的放电功率以控制所述增程器释放所述预留发电功率为车辆充电;在车辆充电达到预设时间段后,获取车辆的当前电量为第二电量;若第二电量小于等于第一电量,则根据预设整车能量管理规则限制热管理模块输出的热管理功率、驱动模块输出的驱动功率并控制增程器以目标补偿功率进行输出,以释放补偿功率为车辆充电。有效缓解车辆电池压力,保证动力电池电量不会持续下降。
