DuPont makes advances in battery safety, heat and e-powertrain efficiency

Zytel hybrid bobbin

Vehicle electrification is a major trend driving desirable sustainability outcomes for businesses, communities, and our planet. This week at the Fakuma trade show, technical experts from DuPont are going to discuss how recently introduced solutions and services from the company support EV battery and thermal management optimization, e-motor and power electronic efficiencies, safety, lightweighting, durability, connectivity, and infrastructure.

“Polymer-based solutions that exhibit excellent mechanical properties and can resist heat, chemicals, and fluids are absolutely essential in supporting demanding applications for vehicle electrification,” said Giacomo Parisi, global marketing director for automotive electrification, DuPont Mobility & Materials. “We have been successful in this industry for more than 100 years because customers know they can trust our ability to develop the solutions they need today and in the coming years.” 

DuPont is working on a new hybrid bobbin produced from its Zytel HTN that supports thermal management in e-motors. It has developed a new plastic/metal hybrid cooling plate where a channel plate made from its Zytel HTN is chemically bonded to aluminium to create a solution that improves durability and thermal management performance of battery cells. The company claims that its Zytel and Crastin stable orange materials meet the reliability and performance requirements for high-voltage terminals and connectors, busbars, switches, and relays. It has been reported that the Zytel and Zytel HTN family of electrically friendly, heat-stabilized resins can handle contact with aggressive fluids and low- to high-voltage loads in various temperature and humidity conditions. DuPont has also announced Crastin HR hydrolysis stabilized PBT for sophisticated sensor systems and electronic components like switches, connectors, and electronic control units.

In addition, DuPont recently announced the opening of three Centers of Excellence for vehicle electrification. These technology centers, located in Europe and China and supported by other global R&D and technical service centers, will support ongoing developments in three key areas – battery safety, thermal management, and e-powertrain efficiency.
