The embodiment of the invention discloses a charging circuit and a charging abnormity processing method. The charging circuit comprises a power supply, a charging switch module, a detection module and a discharging module, the charging switch module is connected between the power supply and the charging interface; the discharging module is connected to the charging interface; and the detection module is used for determining the charging state based on battery parameters of the battery connected with the charging interface detected in the charging process, controlling the charging switch module to be switched off when determining that an abnormal charging state occurs, and discharging the battery through the discharging module. According to the technical scheme, the detection module is arranged to monitor the state of the battery in real time in the charging process, and when the charging abnormal state occurs, the electric quantity in the battery is released through the discharging module, so that the activity of metal ions in the battery is reduced, and the probability of spontaneous combustion of the battery is reduced.
本发明实施例公开了一种充电电路及充电异常的处理方法。该充电电路包括:电源、充电开关模块、检测模块和放电模块;充电开关模块连接在电源与充电接口之间;放电模块连接于充电接口;检测模块用于基于充电过程中检测到的充电接口所连接电池的电池参数确定充电状态,并在确定出现充电异常状态时控制充电开关模块断开,通过放电模块对电池进行放电。本发明实施例的技术方案,设置检测模块在充电过程中实时监测电池的状态,当发生充电异常状态时,通过放电模块将电池内电量释放,减少电池内金属离子的活性,降低电池自燃的概率。
