摘　　要：利用参数识别技术对退役动力电池进行分选,实现退役电池的二次利用。研究二次利用前动力电池的性能状况,对电池的剩余容量、剩余寿命、电池的荷电状态(state of charge,SOC)、电荷健康度(state of health,SOH)等影响电池性能的参数进行识别,并根据获取的相关数据来评估退役电池组当前状态下的性能,预测电池的剩余寿命,为动力电池二次利用的参数识别提供理论依据。In order to use the parameter identification technology to sort the retired batteries and realize thesecondary utilization of batteries, the performance of the retired power battery such as residual capacity, residual life, SOC, SOH and others are identified by appropriate technical method. The performance of retired batteries under the current state is evaluated according to the relevant data obtained, which provides theoretical basis for parameter identification of secondary utilization of power batteries.
