The invention relates to a battery charging control method, a charging and discharging control system and a discharging control method. The battery charging control method provided by the invention is applied to a battery system comprising at least one group of batteries, and comprises the following steps: acquiring charging power of the batteries, and obtaining first charging current of the batteries according to the charging power; correcting the first charging current of the battery according to a pre-configured first charging correction coefficient to obtain a second charging current of the battery; determining a second charging correction coefficient of the battery according to the required charging amount of the battery; and correcting the second charging current of the battery according to the second charging correction coefficient of the battery to obtain a third charging current of the battery, and charging the current battery pack based on the third charging current. According to the scheme, overcharge of the battery can be avoided, the consistency of the battery packs in the battery system is improved, reliable operation of the battery system is facilitated, and the service life of the battery system is prolonged.

    本发明涉及一种电池充电控制方法、充放电控制系统及放电控制方法。本发明提供的电池充电控制方法应用于包含至少一组电池的电池系统,该电池充电控制方法包括:获取电池的充电功率,并根据充电功率得到电池的第一充电电流;根据预先配置的第一充电修正系数对电池的第一充电电流进行修正,得到电池的第二充电电流;根据电池所需充电量确定电池的第二充电修正系数;根据电池的第二充电修正系数对电池的第二充电电流进行修正,得到电池的第三充电电流,并基于第三充电电流对当前组电池进行充电。本发明的方案能够避免对电池的过充,并且提高了电池系统内部电池组间的一致性,有助于电池系统的可靠运行,提高了电池系统的使用寿命。
