based on buck-boost converters is proposed in this study. By using equivalent
circuit model of the battery cells, proposed active balancing circuit is examined
in detail. An algorithm is developed to actively control the balancing
operation. The algorithm is also utilized to prevent any failures in the
balancing operation. The proposed system is simulated under low and heavy load.
The simulation results indicates that 25 mV imbalance between potentials of two
battery cells can be balanced out in approximately 147 seconds under low load
and in 127 seconds under high load. </span> <span style="font-size:10pt;"> </span> </p> <p> </p>}, number={4}, publisher={Süleyman Demirel Üniversitesi}
