摘要： The present invention relates to a cell balancing method for a high-voltage battery pack, and the method comprises steps of a) measuring an electromotive force of each cell composing the battery pack; b) selecting the cell to be balanced based on the electromotive force of the each cell; c) computing a total amount of charges used for balancing of the cell to be balanced; d) obtaining an accumulative amount of charges by accumulating an amount of current consumed for the balancing while performing the balancing of the cell to be balanced; and e) completing the balancing of the cell to be balanced when the accumulative amount of charges equals the total amount of charges.
