Battery sodium precipitation detection method and device, electronic equipment and storage medium

The invention discloses a battery sodium precipitation detection method and device, electronic equipment, a storage medium and a program product. The battery sodium precipitation detection method comprises the following steps: acquiring a battery data set; inputting the battery data set into the initial detection model for training to obtain a target detection model; and inputting the battery sodium precipitation amount and the battery resistance value under the same charging and discharging strategy into the target detection model to obtain the corresponding battery health degree. Taking the battery sodium precipitation amount change data, the battery impedance value change data and the battery health degree change data under different charging and discharging strategies as a data set; training the initial detection model by using the data set so as to establish a mapping relation between the sodium precipitation amount of the battery, the impedance value of the battery and the health degree of the battery, thereby obtaining a target detection model; and finally, inputting the sodium precipitation amount of the battery and the resistance value of the battery under the same charging and discharging strategy into the target detection model, so that the corresponding health degree of the battery can be accurately obtained.
