Simulations speed development

Xiao Hu, Lead Engineer with ANSYS, Inc explains how modern computational fluid dynamics can improve the design process for large scale batteries.

Large lithium-ion batteries appear to be the main contender as power sources for the EV and HEV market but proper thermal management is crucial to prevent overheating and uneven heating across a large battery pack, which can lead to degradation, mismatch in cell capacity and potentially thermal runaway. The design of the thermal management system requires knowledge about the cooling system as well as the amount of heat that will be generated by cells . . .
