摘　　要：着眼于LiMn_2O_4锂离子电池和LiFePO_4锂离子电池在电动汽车动力领域的应用,以4种国产动力锂离子电池为对象,对其电压特性进行了试验和研究。研究结果表明:LiMn_2O_4锂离子电池与LiFePO_4锂离子电池的电压特性有显著差别;低温对LiFePO_4锂离子电池的电压特性有显著性影响;PNGV模型适用于LiFePO_4锂离子电池在动态脉冲电流工况下的电压特性仿真。The focus of this research is LiMn2O4 Li-ion battery and LiFePO4 Li-ion battery for electric vehicles in the field of application of power. The voltage characteristics of four kinds of domestic power LIB batteries are tested and researched. The test results show that, there are significant differences on the voltage characteristics between LiMn2O4 LIB and LiFePO4 LIB. Low temperature has the significant influence on LiFePO4 LIB＇s voltage characteristics; PNGV model is applicable to the simulation of voltage characteristics when LiFePO4 LIB is under the dynamic pulse current driving schedule.
