The invention belongs to the technical field of lithium batteries, and particularly provides a charging method of a lithium battery system. The method comprises the following steps that battery charging abnormal state information data are obtained and preliminarily analyzed, corresponding battery abnormal state analysis is obtained, and the battery abnormal states are divided into a battery overall abnormal state and a battery internal single body abnormal state; according to the overall abnormal state analysis of the battery in the abnormal state of the battery, the overall abnormal state information of the battery is obtained through analysis, so that the battery enters a battery maintenance state, and the corresponding charging power is properly changed; according to the method and the device, the situation that an accident is caused by the fact that abnormity possibly exists during current vehicle charging can be solved, and a safer charging mode is brought about, so that the abnormal state of the single battery in the battery is analyzed, and the abnormal information of the single battery is obtained, and the abnormal single battery enters a battery maintenance state.

    本发明属于锂电池技术领域,尤其提供一种锂电池系统的充电方法。所述方法包括以下步骤:获取电池充电异常状态信息数据并进行初步分析,得到相应的电池异常状态分析,其中电池异常状态分为电池整体异常状态以及电池内单体异常状态;根据对电池异常状态中的电池整体异常状态分析,分析得到电池整体异常状态信息,使得进入电池维护状态,适当改变相应的充电功率;对电池异常状态中的电池内单体异常状态进行电池单体状态分析,从而获取异常的电池单体信息,并使得异常的电池单体进入电池维护状态本发明能够解决当期车辆充电时可能存在异常导致意外发生的情况,带来更加安全的充电方式。
