Abstract

This article presents an approach for balancing serially connected battery strings with high efficiency energy transferred. The efficiency of this balancing process is accomplished by channeling an excess energy through a DC Link Bus rather than done serially. Using this proposed technique with converter which was 80 percent efficiency, the equalized efficiency of balancing process is increased more than the conventional techniques at least 12.80 percent. By applied this proposed technique to the charge equalized system, the unbalance charging problem can be eliminated. The validity of this approach can be supported by computer simulation and experimental result. ฉ2009 IEEE.
