The invention relates to the technical field of battery safety, in particular to a power battery temperature monitoring processing method, device and equipment and a storage medium, and the method comprises the steps: recognizing the temperature data in a power battery pack, and setting a preset number of temperature data sets; if the deviation between the first temperature data in the current temperature data set and the other temperature data exceeds a deviation threshold and the first temperature data exceeds an over-temperature threshold, judging whether second temperature data exceeding the over-temperature threshold exists in the power battery pack or not; if the first temperature data does not exist and the duration of the first temperature data exceeding the over-temperature threshold value is greater than a preset duration, determining that a temperature redundancy fault occurs, and performing power limitation; and if the power battery pack has the temperature redundancy fault in the continuous preset number of driving cycles, forbidding high voltage on the power battery pack. The power performance and the safety requirement of the battery are both considered, stable power output is provided, and the safety of the power battery pack is fully guaranteed.

    本申请涉及电池安全技术领域,特别是涉及到一种动力电池温度监控处理方法、装置、设备及存储介质,其中方法包括:识别动力电池组内的温度数据并设立预设数量的温度数据组;若当前温度数据组中存在第一温度数据与其他温度数据的偏差均超出偏差阈值且所述第一温度数据超出过温阈值,判断所述动力电池组内是否存在第二温度数据超出所述过温阈值;若不存在,且所述第一温度数据超出所述过温阈值的时长大于预设时长,则判定为温度冗余故障,并进行功率限制;若所述动力电池组在连续预设次数的驾驶循环内存在温度冗余故障,则禁止所述动力电池组上高压。本申请兼顾了电池的动力性能和安全要求,既提供稳定的动力输出,又充分保障动力电池组的安全性。
