Battery pack balancing method and system for a vehicle, comprising: - a plurality of battery cells (1), - a battery balancer (2) connected to each battery cell (1) having a resistance R B (3), - a cell monitor (4) configured to measure the voltage of each battery cell (1) and to manage the battery balancer (2), connected through an electrical wire (5) being the resistance of the electrical wire R C (6). The balancing method comprises the following steps: - modelling each electrical wire (5) connecting the cell monitors (4) and the battery cells (1), and - performing a balancing process of the battery cells (1) compensating the error of the voltage measurement.
