The invention discloses a battery charging control method, a battery management system and a vehicle. The battery charging control method comprises the following steps: acquiring a current battery temperature, a current battery remaining capacity and a current charging frequency; a target charging current MAP table is obtained from a charging current MAP table database according to the current battery temperature, the current battery remaining capacity and the current charging times, and the charging current MAP table database comprises a plurality of corresponding relation tables of the battery temperature, the battery remaining capacity and the charging current corresponding to different charging times; querying a target charging current MAP table according to the current battery temperature and the current battery remaining capacity to obtain a target charging current; and controlling battery charging according to the target charging current. By adopting the method, the problem that the battery cannot be charged due to over-high temperature caused by repeated charging of the battery can be reduced, and the user experience is improved.
本发明公开了一种电池充电控制方法、电池管理系统和车辆。所述电池充电控制方法包括:获取当前电池温度、当前电池剩余电量和当前充电次数;根据当前电池温度、当前电池剩余电量和当前充电次数从充电电流MAP表数据库中获得目标充电电流MAP表,其中,充电电流MAP表数据库包括多个对应不同充电次数的电池温度、电池剩余电量和充电电流的对应关系表;根据当前电池温度和当前电池剩余电量查询目标充电电流MAP表,以获得目标充电电流;根据目标充电电流控制电池充电。采用该方法可以减少因电池多次充电使得温度过高而造成无法充电的问题,提高用户体验。
