摘要：
In this paper, a reconfigurable multi-cell battery pack with the capability of simultaneous charging and discharging that can be applied in portable electronic devices is proposed. With the control of switches and charging current, cell balancing can be achieved under simultaneous charging and discharging. The proposed topology's operation modes are analyzed based on the charging and load current. Comparisons to similar works are made. A prototype circuit has been built to verify the operation modes, and its experimental results show that the peak efficiency of the proposed topology reaches 97 % when the load current is at 0.2 A without charging.
