In this paper, an efficient and reconfigurable multi-cell battery pack for portable electronic devices with simultaneous charging and discharging capability is proposed. Based on the status of the load current, the operational principle of the proposed topology is analyzed to achieve cell balancing under simultaneous charging and discharging. Balancing characteristics are then analyzed, and a prototype circuit has been built to verify the proposed topology with the experimental results. Finally, the proposed topology is compared to other cell to cell topologies in converter type, size, and balancing speed. |
