Abstract Recently, various alternative battery pack design studies have been conducted to achieve the safety requirements of an electric vehicle (EV). This article assesses the performance of a mechanical battery pack structure on the basis of energy absorption and packaging efficiency, thus enabling optimization of the EV’s overall performance in addition to the actual crash performance. Commercially available battery pack structure is evaluated in competition with alternative geometric concepts. The study determines the maximum possible packing efficiency on the basis of geometric considerations and also evaluates its energy absorption characteristics using crashworthiness indicators. The method is limited to the evaluation of the battery pack structures at component level using the finite element method subjected to static and dynamic simulations under the side pole impacts according to international crash standards. During the dynamic simulations, the energy absorbed by the battery cells is also evaluated using simplified crushable foam material.

考虑创新电池组设计封装效率的有限元分析

摘要 最近,已经进行了各种替代电池组设计研究,以实现电动汽车 (EV) 的安全要求。本文根据能量吸收和封装效率评估机械电池组结构的性能,从而在实际碰撞性能之外优化电动汽车的整体性能。在与替代几何概念的竞争中评估市售电池组结构。该研究在几何考虑的基础上确定最大可能的填充效率,并使用耐撞性指标评估其能量吸收特性。根据国际碰撞标准,该方法仅限于使用有限元方法在侧杆撞击下进行静态和动态模拟,在组件级别评估电池组结构。在动态模拟过程中,还使用简化的可压碎泡沫材料评估电池单元吸收的能量。
