Measuring Performance of Critical Constraints: Thermal Management in Electric Vehicle Systems
Electric vehicles are poised as a viable alternative to gas powered transportation with many major countries aiming to completely switch to electric within the next few decades. While electric vehicles have clear benefits in terms of environmental effects, there are still many hurdles to overcome before this can truly be realised. One of which is related to the battery/energy storage systems required to power the vehicles.
Since their development over 30 years ago, lithium ion batteries (LIBs) have become the preferred technology for energy storage in a wide swath of industrial and commercial applications. Large sized LIBs are of particular interest for applications in electric vehicles owing to their light weight and high energy densities. Unfortunately, increasing LIB size incurs a greater risk of safety problems due to thermal runaway in the battery. Many companies are working on various forms of thermal management (cooling systems) to help combat these issues which can take the form of either passive, active or hybrid systems. In all cases, the thermal properties of the materials being used all contribute to the overall performance of the cooling system.
Being able to measure thermal properties such as thermal conductivity and specific heat capacity is of the utmost importance to those working on these problems. In this webinar, we explain some of the factors influencing thermal runaway issues and explore a few examples of how some groups are working to solve them. This webinar will be of interest to individuals involved with computational analysis or developing new R&D efforts, where consistent, reliable characterization is a necessity.
