摘　　要：为研究聚合物锂离子电池特性,用三种试验方法,对一种标称容量为20Ah的商用锂离子电池,试验研究电池特性。第一种为常规方法,将不同荷电状态电池静置12h后测量其开路电压;第二种方法为快速测试方法,每种荷电状态电池静置1min后测量其端电压;第三种方法是测量不同荷电状态电池静置30min后的端电压,用测量数据外推开路电压和电池模型参数。测试结果表明:采用30min休息间隔的脉冲充放电可有效用于测试电池的开路电压(OCV)曲线和电池电特性参数。The electrical characteristics were analyzed using three experimental methods with a commercial 20-Ah polymer lithium-ion battery. The first method is a conventional test, in which the voltages are measured as the steady open-circuit voltages after 12-h rest at different state of charge. The second is the rapid test for measurement of open circuit voltages during the charge and discharge pulse with l-rain rest, with the third being the constant-current pulse test with 30-rain rest for parameter identification based on the equivalent circuit model. The measurement results show that the constant-current pulse method with 30-minutes relaxation is effective to derive both the open-circuit voltage （OCV） curve and the electrical parameters.
