Michele Gosso & Antonio Fiumara

Fiat Research Center, Orbassano, Italy

在意大利的菲亚特研究中心,Michele Gosso 和 Antonio Fiumara 正在努力开发为电动汽车和混合动力汽车供电的方法。他们必须将单个锂离子电池软包电芯组装到电池组中,以产生所需的 350V 电压,并在使用期间令电池组充分冷却。同时,他们希望尽可能让电池组保持小巧轻便。

于是他们利用 COMSOL Multiphysics 软件研究在设计中的对流空气冷却的表面分布情况。这样能够让他们发现电池中的热点,并研究内部温度分布情况,这些都无法通过其他方法实现,因为将热电偶嵌入到电池软包来获得可靠结果有一定难度。而利用 COMSOL Multiphysics 软件创建的这个模型帮助他们节省了 70% 的设计时间。他们希望将来各式各样的汽车都能采用这种更小巧更轻便的电池组。
