The invention relates to the technical field of vehicle-mounted battery charging, and discloses a vehicle-mounted battery charging power control method and device, a vehicle and a medium, and the method comprises the steps: obtaining the current battery charging power boundary and the current actual charging power of a vehicle-mounted battery in the driving process of a target vehicle; based on the difference value between the current battery charging power boundary and the current actual charging power, the charging power overcharge risk level of the vehicle-mounted battery is determined; determining a charging power adjustment scheme based on the charging power overcharge risk level; and performing operation control on the target vehicle based on the charging power adjustment scheme. The charging power overcharge risk level of the vehicle-mounted battery is determined by identifying the difference value between the current battery charging power boundary and the current actual charging power of the vehicle-mounted battery, and the charging power adjusting scheme is determined according to the corresponding risk level to perform operation control on the vehicle, so that the safety risk of overcharge fault of the battery is avoided; the vehicle driving stability is improved, and the driving experience of a user is improved.

    本发明涉及车载电池充电技术领域,公开了车载电池充电功率控制方法、装置、车辆及介质,该方法包括:获取目标车辆在行驶过程中车载电池的当前电池充电功率边界及当前实际充电功率;基于当前电池充电功率边界与当前实际充电功率的差值,确定车载电池的充电功率过充风险等级;基于充电功率过充风险等级确定充电功率调节方案;基于充电功率调节方案对目标车辆进行运行控制。本发明通过识别车载电池的当前电池充电功率边界及当前实际充电功率的差值来确定车载电池的充电功率过充风险等级,并根据对应的风险等级确定充电功率调节方案对车辆进行运行控制,以避免电池报过充故障的安全风险,提高车辆行驶的稳定性,提升用户的驾驶体验。
