Abstract :
Electric Vehicle (EV) and Hybrid EV (HEV) require higher voltage than what a single storage cell can output, so a large number of cells are needed to be connected in series. For the series connected storage cells, the voltage equalizer is required. In this paper, modularized LC resonant switched capacitor cell voltage equalizer is proposed. By means of modularizing and Zero Current Switching (ZCS), the proposed equalizer reduces the equalization time and switching losses.
