摘要

提出了一种基于buck-boost拓扑的串联电池组均衡技术。该方案利用buck-boost操作将能量从充满电的电池转移到最弱的充电电池。该操作可使电池保持在相同的电量和电压水平。与以前的电池均衡器方案不同，新的电池均衡器只使用一个磁性元件，因此成本低，体积小。实验结果验证了所提出的电池均衡器的有效性。

A New Buck-boost Type Battery Equalizer

A new technique based on buck-boost topology is proposed to equalize a series-connected battery stack in this paper. The proposed scheme transfers the energy from fully charged battery cell to the weakest charged battery using buck-boost operation. This operation maintains batteries at the same charge and voltage level. Unlike previous battery equalizing schemes, the new battery equalizer uses only one magnetic component, resulting low cost and small size. Experiment results are provided to verify the operation of the proposed battery equalizer.
