The invention relates to the technical field of battery monitoring, particularly provides a battery abnormity monitoring method, and aims to solve the problem of low abnormity judgment accuracy of a power battery monitoring method. In order to achieve the purpose, the battery abnormity monitoring method comprises the following steps that appearance information data and internal historical state data of a battery are obtained, and the appearance information data of the battery are obtained in the battery replacement process; calculating a first scoring result based on the appearance information data; calculating a second scoring result based on the internal historical state data; performing information fusion on the appearance information data and the internal historical state data; calculating a third scoring result based on the information fusion result; judging whether the battery is abnormal or not according to the first scoring result, the second scoring result and the third scoring result; and when the battery is abnormal, giving an abnormal warning. According to the technical scheme provided by the invention, relatively high abnormity judgment accuracy and relatively rapid battery abnormity judgment can be obtained, the user experience is relatively good, and abnormity can be found in advance and warned.

    本申请涉及电池监测技术领域,具体提供一种电池异常监测方法,旨在解决动力电池监控方法异常判断精确度较低的问题。为此目的,本申请的电池异常监测方法包括以下步骤:获取电池的外观信息数据和内部历史状态数据,电池的外观信息数据为换电过程中获取;基于外观信息数据,计算第一评分结果;基于内部历史状态数据,计算第二评分结果;将外观信息数据和内部历史状态数据进行信息融合;基于信息融合结果,计算第三评分结果;根据第一评分结果、第二评分结果和第三评分结果,判断电池是否异常;在电池异常时,发出异常警告。本申请提供的技术方案可以获得较高的异常判断精确度和较快速的电池异常判断,用户体验较好,有利于提早发现异常并警告。
