Thermal Management

Optimizing thermal management systems for EVs with advanced materials

Automakers are increasingly investing in electric vehicles (EVs) to meet stringent CO₂ emission regulations set by governments, as well as consumer demand for greener vehicles. As automotive brands bring more EVs to market, they need to address the safety issues related to electric engine batteries.

In EVs, thermal management systems (TMS) are critical to keeping battery packs within the optimal temperature range to improve engine efficiency and service lifetimes as the EV operates. Additionally, TMS continue running when the EV is being charged to prevent battery pack thermal runaway – which is especially critical for fast EV charging. This requires manufacturers to ensure the thermoplastic components in TMS are tested to withstand more than 10,000 hours of exposure to coolant chemicals.

Understand why choosing Envalior in thermal management systems

Envalior supplies a complete portfolio of materials optimized for TMS components and works directly with our customers to identify the materials best suited to the specific needs of their applications. Xytron^TM, our leading PPS compound, is ideal for developing TMS components that require the highest hydrolysis and heat aging resistance, including thermal management modules, coolant control valves and electric water pumps.
