摘　　要：梯次利用退役动力锂电池不一致性更加明显,其电压、内阻、容量离散性更大,现有均衡技术不能满足要求。介绍了一种智能分时的主动被动协同均衡技术,该技术结合现有均衡技术的优点,能够实现对梯次利用电池的高效和快速均衡。验证结果表明,基于该技术的均衡电路能够满足电池梯次利用工作要求。The inequality of retired lithium-ion power batteries is much more obvious,and their voltage,internal resistance,capacity deteriorate seriously and have great dispersion.Therefore,any kind of existing equalization techniques can not meet the requirements for battery reuse.A novel intelligent time sharing hybrid equilibrium technique for retired power battery was described,namely cooperation equalization model including active and passive methods,combining the advantages of the existing balance methods.This technology can meet the equalization requirements for reuse of retired lithium-ion power batteries as a high-efficient way,which is verified by the experimental results in detail.
