| description | The invention provides a battery pack electric leakage diagnosis method and system, electronic equipment and a storage medium. The method comprises the following steps: determining whether the electric leakage diagnosis system is in a normal working state or not; if yes, differencing the plurality of signal values from a preset value one by one to obtain a plurality of corresponding difference values, and judging whether a marked difference value greater than a first preset threshold value exists in absolute values of the plurality of difference values or not; if yes, marking a specific electric signal corresponding to the marking difference value as a suspected electric leakage signal; according to the acquisition serial numbers of the plurality of electric signals, querying a specific acquisition serial number corresponding to the suspected electric leakage signal, and analyzing whether the specific acquisition serial number has periodicity; and if yes, judging that the battery pack has an electric leakage |
