Test Analysis of Traction Battery Peak Power 总被引:1,自引:0,他引:1
The test process of electric vehicles (EVs) traction battery peak power is analyzed in detail. Aimed at a special ““traction““ design of versatile battery-HORIZON C^2M Battery, the features are introduced. According to the peak power test schedule, the test parameters of HORIZON C^2M Battery are calculated and the charging and discharging experiments are carried out. The sustained (30 s) discharge power capability of battery at 2/3 of its open circuit voltage at each of various depths of discharge is determined. The dynamic internal resistance under peak power test is established. Considering the temperature impact during discharging, the peak power capability at each of various depths of discharge is corrected. The correctness of peak power test is validated by combining theory analysis with test results. 相似文献

电动汽车用锂离子电池低温性能和加热方法 总被引:1,自引:0,他引:1
为提高锂离子动力电池的低温充放电性能,以锰酸锂80 Ah电池单体为研究对象,进行低温下电池充放电特性实验研究,提出宽线金属膜加热方法,并对-40 ℃下的电池单体进行加热和放电实验,采用不同的预热时间,对加热后电池放电性能进行比较实验.结果表明:低温下,电池的充放电性能显著衰减,采用宽线金属膜加热方式能显著提升电池的低温放电性能;同时,通过对比实验发现,仅增加预热时间对提高低温电池放电性能的效果有限. 相似文献
