| Abstract: | 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 8A charged,cooling effect was good. |
