The invention discloses a battery safety detection method, device and equipment and a storage medium, and relates to the technical field of lithium battery detection, in particular to the battery safety detection method, device and equipment and the storage medium. The battery safety detection method is applied to the electric vehicle, and comprises the following steps: reading time sequence data of the electric vehicle during charging to obtain initial time sequence data, performing change detection on the initial time sequence data to obtain a change detection result, and performing resampling in the initial time sequence data according to the change detection result to obtain target time sequence data, and according to the target time sequence data, performing volatility calculation processing to obtain a target volatility, and according to the target volatility, performing battery safety identification to obtain a battery safety detection result. Safety diagnosis can be carried out by acquiring the time sequence data during charging of the electric vehicle, and the implementation difficulty of battery safety diagnosis is reduced.

    本发明公开了一种电池安全检测方法、装置、设备及存储介质,涉及锂电池检测技术领域,尤其是涉及一电池安全检测方法、装置、设备及存储介质。电池安全检测方法应用于电动车,电池安全检测方法包括:读取电动车在充电时的时序数据,得到初始时序数据,对初始时序数据进行变化检测,得到变化检测结果,根据变化检测结果在初始时序数据中进行重采样,得到目标时序数据,根据目标时序数据进行波动率计算处理,得到目标波动率,根据目标波动率进行电池安全识别,得到电池安全检测结果。本发明能够通过获取电动车充电时的时序数据进行安全诊断,降低了对电池安全诊断的实施难度。
