The method (3000) comprises: after it is confirmed that all battery cells (C11-C48) connected to voltage collection apparatuses (2001, 2002, 2003) are in a normal state, charging or discharging a battery pack (1400) at a preset current (3001); acquiring sampling voltage values of the plurality of battery cells (C11-C48) by means of the voltage collection apparatuses (2001, 2002, 2003) (3002); according to the acquired sampling voltage values of the plurality of battery cells (C11-C48), determining, from a plurality of modules (1401, 1402, 1403, 1404), battery cells (C31, C21) that need to undergo sampling voltage compensation, and calculating impedance voltages of cross-module busbars (1501, 1502) (3003); and according to the impedance voltages of the cross-module busbars (1501, 1502), performing sampling voltage compensation on the battery cells (C31, C21) that need to undergo voltage compensation (3004). The positions of battery cells (C31, C21) that need to undergo sampling voltage compensation and the magnitude of impedances of busbars (1501, 1502) can be determined, and voltages collected by voltage collection apparatuses (2001, 2002, 2003) at the positions of the battery cells are compensated, such that the collected voltages of the battery cells are consistent with the actual voltages of the battery cells.",
