摘要
Abstract
The phenomenon of nonuniform current and voltage distribution also occurs under electric vehicles accelerating,climbing or driving on a bad road conditions.The laws between resistance with ambient temperature,SOC,discharge rate and cycle life were studied by the combination of the high-precision test instrument with the water tanks.Meanwhile,the variation law of entropy coefficient in different ambient temperatures and SOC was also discussed.The experimental results show different working conditions have different influence on the total internal resistance and entropy coefficient.It is necessary to monitor the distribution of module voltage and current at real time.关键词
