Abstract :
The low stress voltage balance charging circuit for series connected batteries based on buck-boost topology is present and experimented. In the proposed circuit, the number of circuit components and the switches stress voltage are lower than the conventional system. By connecting the proposed circuit and applying the proposed control algorithm with the series battery pack, the unbalance charging problem which usually occurred in the series connected charging system can be eliminated.
