摘要： An apparatus balances a charging voltage of each battery cell of a battery pack. The apparatus includes a discharge resistor installed on a conductive line connected to both ends of a battery cell in parallel; a balance signal relay unit for relaying a charging voltage of the battery cell according to a balance control signal; and a discharge switching unit for receiving the relayed charging voltage of the battery cell as a driving voltage and connecting the battery cell to the discharge resistor to discharge the battery cell if the driving voltage is over an effective voltage level. This apparatus prevents overcharging of a battery cell, caused by a failure of a control processor, while balancing a charging voltage of battery cells. Also, the control processor may be protected against an electric impact by electrical insulation from a discharge circuit. Accordingly, the safety of the battery pack is improved.
