基于ANSYS的动力电池包防水透气阀的计算
|
摘要
防水透气阀是动力电池包的的关键零部件,其一方面影响到箱体IP67防护性能,同时也关系到箱体内外气压的平衡,因此合理选择防水透气阀对提高动力电池包的可靠性至关重要。本文从动力电池箱内空气膨胀速率和防水透气阀排气速率平衡出发,详述了箱体内空气膨胀速率的计算过程,根据其与防水透气阀排气速率的平衡点,求出箱体鼓胀高度,并与电池箱暴晒试验鼓胀高度进行了对比。
the key component of the lithium bayyery box is the waterproof permeability valve,which is not only influenced the protective performance of the IP67 box, but alsorelated to the air pressure balance of the box, so it is very important box. t that choose the waterproof permeability valve to improve the reliability of the battery Starting from the balance between the rate of air expansion in the lithium batterybox and the exhau rate of the wat erproof permeability valve, the calculation processofthe air expansion rate in the box is described. According to their balance, the bulging height of the box is obtained, which is compared with the bulging height of the battery box in solar radiation test.
