Abstract
A battery management system (BMS) including a memory in which a resistance value of a wiring resistor of an electrical connection path between a battery cell and the BMS is stored, and a processor configured to measure a first cell voltage of the battery cell and to remove a voltage error due to the wiring resistor reflected in the measured first cell voltage based on the resistance value of the wiring resistor stored in the memory to estimate a second cell voltage that is an actual voltage of the battery cell.
