The invention discloses a charging system, a vehicle, a method and a storage medium, and the system comprises a power battery provided with a plurality of battery packs, and a charging circuit with a variable topological structure. The detection part is used for detecting the actual access voltage of each charging port; and the battery management system is used for adjusting the charging circuit as a target circuit according to the actual access voltage of each charging port, changing the series-parallel connection relationship of the plurality of battery packs in the power battery as a target relationship, and charging the power battery according to the target circuit, the target relationship and the actual access voltage. Therefore, the problems that charging piles with different voltages cannot be compatible, the charging piles cannot fully charge batteries, and the total charging current cannot be increased and the charging time cannot be shortened by using double-gun charging in the prior art are solved.

    本申请公开了一种充电系统、车辆、方法及存储介质,其中,系统包括:设置有多个电池组的动力电池和拓扑结构可变的充电电路;检测件,用于检测每个充电口的实际接入电压;电池管理系统,用于根据每个充电口的实际接入电压调整充电电路为目标电路,并改变动力电池中多个电池组的串并联关系为目标关系,根据目标电路、目标关系和实际接入电压为动力电池充电。由此,解决了相关技术中无法兼容不同电压的充电桩,充电桩无法充满电池,并且使用双枪充电无法提升总的充电电流和缩短充电时间等问题。
