The invention provides a battery anomaly detection method and device, electronic equipment, a vehicle and a storage medium. The battery anomaly detection device comprises a pressure sensing unit which is arranged at the bottom of a battery, at least partially covers the bottom surface of the battery, and is configured to obtain pressure information of the bottom of the battery and generate an electric signal based on the pressure information; the signal conversion unit is configured to determine the intrusion displacement of the bottom of the battery based on the electric signal; and the data analysis unit is configured to determine a battery bottom detection result based on the battery bottom intrusion displacement and a preset intrusion threshold. The battery abnormity detection device can effectively monitor quantitative characterization of deformation of the bottom of the power battery, performs real-time detection on long-term accumulated dark damage of the bottom of the power battery, and can be practically applied to electric automobiles.

    本公开提供一种电池异常检测方法、装置、电子设备、车辆及存储介质。所述电池异常检测装置,包括:压力传感单元,设置于电池底部且至少部分覆盖电池底面,被配置为:获取电池底部的压力信息并基于所述压力信息生成电信号;信号转换单元,被配置为:基于所述电信号确定电池底部入侵位移量;数据分析单元,被配置为:基于所述电池底部入侵位移量及预设的入侵阈值确定电池底部检测结果。本公开实施例所述电池异常检测装置可以有效监测动力电池底部变形的量化表征,针对动力电池底部长期累积暗伤进行实时检测,并可以实际应用到电动汽车中。
