摘要： The present invention relates to a balancing apparatus for a battery pack with an over-discharge protection function. The balancing apparatus according to the present invention is for balancing charge voltages in each of the battery cells in the battery pack, and includes a discharge resistance arranged on a wire connected in parallel to both ends of a battery cell; a balance signal relay unit for relaying the charge voltage of a relevant battery cell in accordance with a balance control signal; and a discharge switching unit for taking the charge voltage of the battery cell relayed from the balance signal relay unit, as a driving voltage, and discharging the battery cell by connecting the battery cell and the discharge resistance if the driving voltage is higher than an effective voltage level. The present battery cells avoid being overcharged even upon failure of a control processor during balancing of charge voltages of battery cells. Further, a discharge circuit for balancing battery cells and a control processor are electrically insulated from each other to protect the control processor from electric shock. This enables improved safety of the battery pack.
