The present application discloses a method, a device, and an apparatus for evaluating vehicle battery cell consistency, and a storage medium. The method comprises: a step of acquiring vehicle operation data and selecting valid cell data from the vehicle operation data according to a preset valid data standard; a step of processing the valid cell data by a predetermined cell consistency indicator processing method to acquire cell consistency indicator data; and a step of determining a total indicator deviation value of all battery cells in a current vehicle based on the cell consistency indicator data, and determining that there is a consistency risk in the current vehicle when the total indicator deviation value exceeds a pre-set deviation threshold. The present application achieves a technical effect of enhancing accuracy in evaluating the vehicle battery cell by conducting comprehensive evaluations of the respective consistency indicators of the battery cells based on the total indicator deviation value of the battery cells.
