February 22, 2024
Disclosed are a battery cell sampling voltage compensation method and apparatus and an electric apparatus. The method includes: after confirming that all battery cells connected to a voltage sampling apparatus are in a normal state, charging or discharging a battery pack at a preset current to obtain sampling voltages of a plurality of battery cells using the voltage sampling apparatus; determining, based on the obtained sampling voltages of the plurality of battery cells, a battery cell requiring sampling voltage compensation in a plurality of modules, and calculating an impedance voltage of a cross-module busbar; and performing sampling voltage compensation on the battery cell requiring sampling voltage compensation based on the impedance voltage of the cross-module busbar. In this application, a position of the battery cell requiring sampling voltage compensation and the impedance of the cross-module busbar can be determined.
