The embodiment of the invention discloses a method and device for evaluating the uniformity of cascaded battery packs. According to the method and the device, the disadvantages that the difference of intrinsic parameters (such as open-circuit voltage, available capacity and internal resistance) of single batteries in the battery packs is difficult to be truly described, evaluation indexes are not comprehensive enough, and the applicability is relatively poor in an existing uniformity online evaluation technique are solved. A distance similarity index calculation method based on a dynamic time warping strategy is developed based on a measured voltage curve of the single batteries, influence factors which cause the voltage difference of the single batteries due to different SOCs can be eliminated in a self-adaption manner, the evaluation of operational characteristic difference of the single batteries in charging-discharging processes is realized, and compared with an existing uniformity extraction method based on voltage difference of each discrete moment, intrinsic information of the batteries is assisted to be excavated; and on this basis, an abnormal battery statistics recognition method based on a stepwise iteration strategy is developed, the uniformity evolution of the cascaded battery packs is realized, and the effective technical support is provided for operation maintenance.
