BATTERY DETECTION METHOD, APPARATUS, AND DEVICE, AND STORAGE MEDIUM

The present invention relates to the field of battery technologies and discloses a battery detection method, apparatus, and device, and a storage medium. The battery detection method includes: acquiring (S10) state of charge values of each battery cell in a battery system at different time points within a preset time; and performing multiple linear regression analysis (S30) based on state of charge values of a reference battery cell, the state of charge values of the battery cells, and timestamps at corresponding time points to obtain a consistency detection result of the battery cells in the battery system. In the present invention, a consistency detection result of the battery cells in the battery system is obtained by just selecting the reference battery cell from the battery cells and comparing the reference battery cell with the battery cells, without using accurate cumulative capacity data. Even without the capacity data, a relative result can be obtained through calculation, thus consistency of the battery cells is calculated, and the accuracy of battery detection is improved.
