摘要
某乘用车AGM蓄电池开发过程中,经过整车台架试验,发现在某环境下电解液温度达到81℃,超过其温度限值75℃。通过Fluent 13.0仿真分析软件和整车对比试验,对增加电池隔热保护套、在蓄电池前增加导流板和增加前端格栅开口面积的3种优化方案进行对比分析和验证。结果表明,增加前端隔栅开口面积的方案最佳,可使电池电解液温度降低到75℃以下。
In the development of AGM battery, the temperature of the inner electrolytic liquid reached to 81 ℃, exceeding its limitation of 75 ℃ in the certain vehicle lab test. Using Fluent 13.0 CAE software and through vehicle lab test, three optimization methods are analyzed and validated by adding a battery cover attachment, air flow baffle attachment and enlarging the front grill opening area. The results show that the best method is to enlarge the front grill opening, making the temperature of the inner electrolytic liquid drop to 75 ℃ below.
