The automotive market is shifting towards development of carbon neutralization techniques, hence there is an exponential increase in the demand for electric vehicles. The driving system in an electric vehicle consists of electric machine, battery, and power electronics (including charging system). The battery system is an assembly of various units - cover, modules, busbar, BMS, floor integrated with cooling system and housing, which undergoes various assembly and functional loads. There are other loads primarily, NVH loads from roads and Crash loads. The impact of crash in a battery could be catastrophic. We can deform module containing lithium-ion cells, and this event is called intrusion that leads to thermal run-away. The scope of work is to develop Explicit dynamic Optimization method for Battery using ESLM to reduce the intrusion levels and optimize part stiffness. The ESLM used here is a combination of shape & size optimization for effective design of battery.
