摘　　要：对MH/Ni电池组(结构A)的充电热效应进行了分析,采用FLUENT软件模拟的方法,研究了两种新型MH/Ni电池组结构(结构B和C)热管理的通风冷却效果.根据计算,分析了流动回流因素对温度场的影响,并提出了结构改进建议.热管理系统C型在电池组充放电试验中的结果表明:8 A充电时电池组内温度升高小于5℃,温度差异小于4℃,系统冷却效果良好.The heat effect of MH/Ni battery pack（type A） in charging was analyzed. In order to study the cooling effect of ventilated flow of the two new structures（type B and C） of MH/Ni battery pack, FLUENT software simulation method was adopted. Based on the calculation results, the factors of circumfluence influences on temperature field were analyzed , and the advice on improving structure was also given. The results of charge/discharge test of type C thermal management system showed that the temperature raise was lower than 5 ℃ and the temperature difference in the battery pack was lower than 4 ℃ when the battery pack was 8 A charged, cooling effect was good.
