The embodiment of the invention discloses a battery charging management method and device, a vehicle and a storage medium. The method comprises the following steps of: acquiring a previous battery temperature of a vehicle at a previous moment, when the previous battery temperature meets a preset power-off condition, acquiring the actual torque of the generator in the time period from the previousmoment to the current moment, and when the actual torque of the generator is the non-zero torque, controlling a range extender of the vehicle to stop charging the power battery in the battery system.According to the technical scheme disclosed by the embodiment of the invention, when the torque working mode of the generator fails, the vehicle range extender is controlled to stop charging the powerbattery in the battery system, the problem that the working life of the battery is shortened due to the fact that the torque control of the generator fails in the charging process of the battery andthe battery continues to be kept in the charging state under the unsuitable charging condition is solved, the service life of the vehicle power battery is prolonged, the endurance performance of a vehicle is improved, and the safety of the vehicle in the driving process is improved.

    本发明实施例公开了一种电池充电管理方法、装置、车辆及存储介质。该方法包括:获取上一时刻车辆的上一电池温度;当所述上一电池温度满足预设断电条件时,获取所述上一时刻至当前时刻时间段内的发电机的实际扭矩;当所述发电机的实际扭矩为非零扭矩时,控制车辆的增程器停止对电池系统中的动力电池充电。本发明实施例的技术方案,当发电机扭矩工作模式失效时,控制车辆增程器停止对电池系统中的动力电池充电,解决了电池充电过程中发电机扭矩控制失效,而使得电池在不适宜充电条件下继续保持充电状态造成的电池工作寿命降低的问题,延长了车辆动力电池的使用寿命,提高了车辆的续航性能并提高了车辆行驶过程中的安全性。
