【摘要】 在实际应用中,由于锂电池单体之间的差异性,经一段时间的充放电后发现各单体电池上、下限电压出现参差不齐的现象,严重影响到系统的性能。针对这种情况提出了上均衡和下均衡的概念,然后对锂电池的上、下均衡电路进行了深入研究。实验结果证明,几种锂电池均衡电路设计的正确性,为研究高性能混合动力系统奠定了坚实的基础。更多还原

【Abstract】 In application of lithium battery, every battery can’t keep consistency after long-time discharge with high current because of difference. The result does harm to the HEV system. The concepts of up equalizer and low equalizer are proposed firstly, then give insight research for both circuits. Experiment results prove the effectiveness of designs firstly. ALL give a good foundation to the next research of high quality HEV system.更多还原
