  • Battery balancing circuit and balancing method thereof and battery activation method
    Patent number: 8643334
    Abstract: Disclosed is a battery balancing circuit for balancing the voltages of a reference battery module and a detachable battery apparatus, which has a load channel, a charging-discharging channel, a MCU and a charging-discharging control circuit. The reference battery module and detachable battery apparatus are connected in parallel. The load channel is connected to the reference battery module. The charging-discharging channel is disconnected from the reference battery module. The load and charging-discharging channels are connected to the detachable battery apparatus respectively through a first and a second switches. When the voltage of the detachable battery apparatus is higher or lower than a threshold value, the MCU controls the first and second switches, such that the detachable battery apparatus is connected to the charging-discharging control circuit through the charging-discharging channel and disconnected from the load channel.
