Thermal Management

The key to wider adoption of electric vehicles (EVs) will be lower-cost models with a more approachable price point. The most expensive component of an EV is the battery pack. As well as increasing the energy density and reducing the cost of the battery cells, another avenue to cost reduction is through more efficient packaging of the cells.

Helium is a finite resource that plays a critical role across several industries including medical imaging, thermal management systems for batteries, aerospace engineering, chemicals and pharmaceuticals, semiconductor manufacturing, fiber optics, particle physics, scientific balloons, and many more.

With the ever-increasing need for heat dissipation, high-performance thermal interface materials with higher thermal conductivity and other properties are becoming essential. Driven by this trend, a number of high-performance TIMs are emerging. This article primarily introduces the advantages and drawbacks of advanced carbon-based TIMs. However, it is worth noting that many other TIMs offer superior performance.

While the focus of the automotive market has been on electrification to meet CO2 regulations, these are not the only regulations that will significantly impact the automotive industry. PFAS are becoming a greater concern throughout multiple industries. With the uncertainty around PFAS regulations, there are a few avenues that automotive players could pursue to replace the refrigerants they use.

IDTechEx expects the printed and flexible sensor market to reach US$960 million by 2034, with a compound annual growth rate of 8.6%. Being connected to infrastructure systems or partnering with suppliers and distributors will help printed sensors take off, alongside their ability to be available at scale, robust, and have long product lifetimes.

Thermal interface materials (TIMs) are composed of thermal fillers and matrix materials. Thermal fillers are highly thermally conductive substances, while matrix materials are typically used to enhance mechanical properties.

With the trend from Si IGBT to SiC MOSFET in electric vehicle (EV) power electronics, the junction temperature is expected to increase from 150°C to 175°C with the potential to exceed 200°C. This brings significant challenges for thermal management.

Electric vehicles, much like combustion vehicles, require a suite of fluids in order to operate optimally. However, the quantities and properties of these fluids can be quite different. With a strongly growing EV market, this presents a large opportunity for not just fluid suppliers but also fluid additives and fluid handling component suppliers.
