  • Battery pack capable of preventing battery cell from high-temperature swelling and method thereof
    Patent number: 8896271
    Abstract: A method for protecting a battery cell from high-temperature swelling, the method includes: sensing a temperature and a voltage of the battery cell; determining whether the sensed temperature of the battery cell exceeds a reference temperature; determining whether the sensed voltage of the battery cell exceeds a reference voltage, when the sensed temperature of the battery cell exceeds the reference temperature; and self-discharging the battery cell in a charge/discharge/standby mode when the sensed voltage of the battery cell exceeds the reference voltage.

  • Battery pack having boosting charge function and method thereof
    Patent number: 8698458
    Abstract: A method of charging a battery pack, the battery pack including at least one battery cell. The method includes comparing a battery cell voltage to a first voltage; comparing the battery cell voltage to a second voltage that is greater than the first voltage; and controlling a current amplifying unit coupled to the at least one battery cell to amplify a current from a charger to the at least one battery cell if the battery cell voltage is between the first voltage and the second voltage.

  • Single unit protection circuit module and battery pack using the same
    Patent number: 7692405
    Abstract: A protection circuit module includes a printed circuit board in which at least one wiring pattern is formed, a conductive pad that is coupled to a wiring pattern of the printed circuit board, and is electrically coupled to a rechargeable battery, and a semiconductor package that is soldered on the wiring pattern of the printed circuit board, so that if the voltage of the rechargeable battery is in the overcharged or over-discharged state, the semiconductor package selectively blocks a charging path or a discharging path of the rechargeable battery.
