Parametric Analysis of a Divided Rocker for Battery Electric Vehicles

The driving range of an electric vehicle can be increased through efficient integration the large battery within structure. In this regard, a divided rocker concept from existing study is investigated, in which into two parts by means division plane. One part remains sided and enables attachment surrounding structures, while other functionally integrated side frame housing. scope paper, several plane concepts for such are created analyzed. crash performance modelled studied on component level using pole test as load case. For different planes, parametric analysis performed varying number chambers profile, chamber width, mass distribution, individual section thicknesses, height air gap between vertical surfaces planes. Several criteria, structural deformation, force, energy absorption, examined. Among parameters, distribution have notable influences, thicknesses planes do not significant influence performance. Lastly, stiffer battery-sided decreasing width strongest effect
