The two major classifications of active cell balancing methods are charge shuttling and energy converting. In this paper, flyback transformer is used as storage element to move energy from one cell to another. A multi-output flyback transformer DC/DC converter prototype is built and tested. The test batteries used in this study were 8 Ah manganese lithium battery pack. Through experiment, the advantages...
The accurate estimation of lead-acid batteries state of charge (SOC) is very important for electric vehicles (EVs).However electrochemical reaction is a very complex process; it is difficult to simulate its dynamic behavior. Various equivalent circuit models have been studied, but can not show a good compromise between real-time and precision. In this paper, a revised model considering temperatures,...
