Improving EV Battery Safety Using Multiphysics Simulation - Archived

Battery safety is one of the main concerns in the development of electric vehicles (EVs). In particular, it is important to address the cascading effects of thermal runaway in lithium-ion batteries. Predicting thermal runaway involves accounting for several different physical phenomena at the cell and pack level, the structural design of the pack, and fluid flow in the battery pack's cooling system. Therefore, multiphysics simulation plays a key role in modeling such phenomena and improving battery safety.

If you would like to learn how to simulate thermal runaway in batteries and meet the safety requirements for EVs, join us for this interactive webinar. You can also ask questions during the live Q&A session.

We will discuss:

• Causes of thermal runaway in batteries
• Modeling different thermal runaway scenarios, including internal and external short circuiting
• Modeling battery abuse: mechanical, electrical, and thermal abuse of batteries
• Thermal analysis of batteries and battery packs by coupling losses from high-fidelity and lumped models
• Simulating thermal runaway propagation
• Computing crucial safety parameters
• Analyzing different battery cooling mechanisms, such as liquid cooling, air cooling, and phase change material cooling
