A method for estimation of consistency for power battery which is composed of a plurality of cells and is configured to provide energy for a vehicle, the method for estimation including: detecting operating voltages for each cell of the plurality of cells in real time during the operation period of the vehicle to obtain a first voltage dataset for the each cell; performing a first filtering process on the first voltage dataset to retain voltage data corresponding to operating currents less than a first threshold, to obtain a filtered second voltage dataset for the each cell; calculating an energy score for the each cell based on the second voltage dataset; and calculating a first consistency score for the power battery based on the calculated energy score for the each cell.
