  • Circuit module and battery pack including the same
    Patent number: 9110100
    Abstract: A circuit module of a battery pack includes a pattern resistor having conductivity; a temperature sensor that is adjacent to the pattern resistor and that senses a temperature of the pattern resistor; and a current detecting unit that is electrically connected to both ends of the pattern resistor, that is electrically connected to the temperature sensor, and that detects a current flowing in the pattern resistor based on a voltage across the ends of the pattern resistor and a temperature of the pattern resistor.
    Type: Grant

  • Hybrid battery pack and methods of charging and discharging the same
    Patent number: 8222865
    Abstract: A hybrid battery pack and methods of charging and discharging the same make it possible to manage at least two power sources by one circuit. The hybrid battery pack includes a first power source having a first switching circuit, a second power source connected to the first power source in parallel and having a second switching circuit, a current sensor serially connected to the first and second power sources to sense the currents of the first and second power sources, and a controller to obtain the voltages of the first and second power sources so that the first and second power sources are not over-charged or over-discharged and to calculate the entire capacity of the first and second power sources using the amount of currents obtained by the current sensor.
