DuPont has introduced its latest innovation, the DuPont™ AmberLite™ EV2X resin, designed to address the growing demand for high-performance glycol-purification solutions in the rapidly expanding e-mobility sector. This advanced solution is tailored to extend the lifespan of electric vehicle (EV) coolant while reducing maintenance requirements associated with glycol, offering superior thermal stability and operational characteristics compared to conventional ion exchange resins currently available in the market.
Noel Carr, DuPont’s marketing manager specializing in e-mobility solutions, highlights the challenges faced by vehicle manufacturers due to increased temperatures within EVs, driven by consumer demands for extended range, faster charging, larger vehicles, and more energy-dense batteries. As a result, many manufacturers are transitioning from air cooling to liquid cooling systems utilizing glycol coolant for effective thermal management. However, elevated operating temperatures can lead to degradation of components and coolants, posing risks such as short circuits and vehicle shutdowns.
Unlike internal combustion engine (ICE) vehicles, EVs require effective management of conductivity within their systems. The degradation of glycol coolant and other thermal management system components can introduce impurities into the cooling loop, elevating conductivity levels. To mitigate this issue, hydrogen fuel cell and battery vehicle manufacturers can incorporate ion exchange filters composed of resilient ion exchange resins capable of withstanding extreme temperatures and operating conditions.
The DuPont™ AmberLite™ EV2X resin plays a crucial role in purification, enhancing the longevity of glycol coolant, coolant loop components, and ion exchange filters. This optimized resin has undergone rigorous testing, enduring extreme conditions of up to 105°C for over 1,000 hours, showcasing exceptional thermal stability and operational reliability compared to conventional ion exchange resins.
Carr emphasizes that degradation of components and coolant within coolant loops is inevitable due to high operating temperatures, which can compromise the performance of glycol coolant and increase conductivity throughout the system. However, with minimal operational degradation even after prolonged exposure to high temperatures, DuPont’s innovative solution instills confidence in suppliers and manufacturers regarding the performance and durability of coolant loops utilized in fuel cell and lithium battery EVs.
DuPont remains at the forefront of electrification in the transportation industry, leveraging its expertise in engineered materials and advanced adhesive technologies to support e-mobility advancements. From application development to technical assistance, DuPont stands ready to address the evolving challenges of e-mobility.
