The invention provides a vehicle battery management method and device, a medium and a vehicle, and belongs to the technical field of vehicles. According to the embodiment of the invention, the current remaining electric quantity of at least two high-voltage batteries can be corrected based on the current battery temperatures of the at least two high-voltage batteries, and the current remaining electric quantity of the at least two high-voltage batteries is corrected. In each charging cycle, the second high-voltage battery with the highest real residual electric quantity can be utilized to charge the first high-voltage battery with the lowest real residual electric quantity, so that the at least two high-voltage batteries can finally reach an electric quantity balance state, and the charging efficiency of the high-voltage batteries is improved. Therefore, the difference between the residual electric quantities of the high-voltage batteries is effectively reduced, the consistency of the charging effects of the at least two high-voltage batteries can be effectively ensured when the vehicle is charged by the external power supply, the charging safety of the batteries can be effectively ensured while the charging efficiency of the batteries is improved, and the service life of the high-voltage batteries is prolonged.

    本申请提供了一种车辆电池管理方法、装置、介质和车辆,属于车辆技术领域,本申请实施例能够基于至少两个高压电池的当前电池温度,对至少两个高压电池的当前剩余电量进行修正,得到更加真实反映高压电池之间剩余电量水平高低的真实剩余电量,进而在每次充电循环中,能够利用真实剩余电量最高的第二高压电池给真实剩余电量最低的第一高压电池充电,使得至少两个高压电池最终能够达到电量平衡状态,进而有效减小各个高压电池的剩余电量之间的差异,使得车辆在被外部电源充电时,能够有效保证至少两个高压电池的充电效果的一致性,在提高电池的充电效率的同时,能够有效保证电池充电安全,延长高压电池的使用寿命。
