摘要：

This paper presents a new converter-based active balancing topology. This equalizer topology consists of a single non-isolated DC/DC converter and cell-to-cell power routing via controlled switches, which are operated as power multiplexers. The design and control strategy of the equalizer are explained. Its performance is assessed in simulation. The equalizer balances an imbalanced battery pack of five monobloc batteries, compensating the initial SOC deviations and keeping the pack balanced from then on. The influence of four battery parameters in SOC divergence is analyzed.
