The invention discloses a method for judging abnormal charging according to a charging power curve. The method comprises the following steps of a) acquiring the charging power curve, a-1) judging whether a user is a new user, a-2) judging whether a complete charging power curve of the user exists and a-3) perfecting thecharging power curve, b) acquiring detected charging power and calculated charging power, b-1) conducting corresponding of a charging power curve, and b-2) conducting corresponding of a charging moment, and c) comparing the detected charging power with the calculated charging power. According to the method for judging abnormal charging according to the charging power curve, whether the abnormal charging occurs or not is judged by judging whether the difference value between the detected power supply power and the calculated charging power is larger than the set value or not, and if the abnormal charging occurs, the alarm information is sent to the user; and the occurrence of battery overheating, even explosion and fire accidents caused by abnormal charging due to reasons such as damp, collision and damage of the charger or aging of electronic components and the like is avoided.

    本发明的根据充电功率曲线判断充电异常的方法,包括:a).获取充电功率曲线,a‑1).判断是否为新用户,a‑2).判断是否存在用户完整的充电功率曲线,a‑3).完善充电功率曲线;b).获取检测充电功率和计算充电功率,b‑1).充电功率曲线对应,b‑2).充电时刻对应;c).检测充电功率与计算充电功率的比较。本发明的根据充电功率曲线判断充电异常的方法,通过判断检测供电功率与计算充电功率的差值是否大于设定值得出是否充电异常,如果出现充电异常则发出报警信息至用户,避免了因充电器受潮、碰撞损坏或者电子元件老化等原因造成充电异常时所导致的电池过热、甚至爆炸和火灾事故的发生。
