The present invention provides a method, system, electronic device, and storage medium of pre-warning for abnormal self-discharge of battery. The method includes: acquiring multiple extreme values of single-cell voltage, multiple extreme values of state-of-charge of single-cell and a time interval of adjacent data within a current working condition cycle of a vehicle battery system, based on a working condition information, a structural information and a consistency information of the vehicle battery system; calculating a self-discharge capacity, a self-discharge energy and an average self-discharge current value of the vehicle battery system based on the extreme values of single-cell voltage, the extreme values of state-of-charge of single-cell and the time interval of adjacent data; judging whether the vehicle battery system is self-discharged according to whether any one of the self discharge capacity, the self-discharge energy and the average self-discharge current value is greater than a preset threshold value; performing a pre-warning of battery safety based on a judgment result.
