The invention discloses a battery charging duration determination method and apparatus, and a battery management system. Comprising the following steps: determining the charging current of an (i + 1) th charging stage, the charging duration of the (i + 1) th charging stage and the first electrical parameter after the (i + 1) th stage according to a corresponding relation table among the first electrical parameter, the temperature and the charging current of the battery, the first electrical parameter after the end of the ith charging stage and the highest single battery temperature after the end of the ith charging stage; according to the current environment temperature, the charging current of the (i + 1) th charging stage, the charging duration of the (i + 1) th charging stage, the highest single battery temperature after the end of the ith charging stage and a battery first temperature rise model, determining the highest single battery temperature after the end of the (i + 1) th charging stage; and accumulating the charging time of each charging stage to determine the total charging duration required by the battery. According to the invention, the accuracy of the remaining time in the charging process can be improved, and a user can reasonably plan the time in the charging process.

    本发明公开了一种电池充电时长确定方法、确定装置以及电池管理系统,包括:根据电池的第一电参数、温度和充电电流之间的对应关系表、第i充电阶段结束后的第一电参数和第i充电阶段结束后的最高单体电池温度确定第i+1充电阶段的充电电流、第i+1充电阶段的充电时长和第i+1阶段结束后的第一电参数;根据当前环境温度、第i+1充电阶段的充电电流、第i+1充电阶段的充电时长、第i充电阶段结束后的最高单体电池温度和电池第一温升模型确定第i+1充电阶段结束后的最高单体电池温度;对各充电阶段的充电时间进行累加确定电池需要的总充电时长。本发明可以提高充电过程中剩余时间的准确度,让使用者在充电过程中合理规划时间。
