Abstract
A battery pack is provided. The battery pack includes first battery cells, a second battery cell coupled to one of the first battery cells, a voltage sensing and balancing circuit for measuring voltages of the first battery cells and for maintaining voltage balance between the first battery cells, a controller that includes an analog-to-digital (A/D) converter, and an analog switch for measuring a voltage value of the second battery cell and for transferring the measured voltage value to the A/D converter. The controller is for controlling charging and discharging of the first and second battery cells. The analog switch includes a flying capacitor, a first switch unit for transferring a voltage between the second battery cell and the flying capacitor, a second switch unit for transferring a voltage of the flying capacitor to the A/D converter, and a first diode for protecting a voltage source from a surge current.
