摘　　要：建立了电动车辆动力电池的性能评价体系:用能量状态CSOE评价和指示电池的能量状态;使用能量衰减系数ξ(E)、相对电压衰减率ηVDR和温升速率ηTRR评价电池的放电特性;采用相对电压差异系数ξ(U)和相对内阻差异系数ξ(r)评价电池的一致性。基于试验结果,对评价体系和评价指标进行了阐述,该评价方法合理可行。The performance evaluation system of power battery was developed and the following evaluation parameters were suggested： state of energy CsoE to signify the energy state of battery, relative voltage dropping rate ηVDR, energy dropping factor ξ（E） and temperature rising rate ηTRR to signify the discharging characteristic. Also the battery cell consistency was discussed and relative voltage difference factor ξ（U） and relative internal resistance difference factor ξ （r） were used as evaluation parameters. Based on the experimental results, the battery evaluation system was explained, the reasonability and feasibility of the evaluation system and parameters were verified.
