DuPont has launched its DuPont™ AmberLite™ EV2X resin for glycol-purification in EVs.
It’s designed to extend the life of EV coolant, and reduce glycol maintenance requirements by offering enhanced thermal stability and excellent operating characteristics compared to standard ion exchange resins currently on the market.
Many manufacturers are turning from air cooling to liquid cooling systems that use glycol coolant to manage these higher temperatures. As EVs gain range, quicker charging times, larger vehicles, and higher energy-dense batteries, the powertrain temperatures increase, creating a strain on the cooling systems. High operating temperatures can degrade parts, components, and coolants, resulting in short circuits and shutdowns of electric and hydrogen vehicles.
The degradation of the glycol coolant and other components housed within the thermal management system releases impurities into the cooling loop, increasing the levels of conductivity. To prevent this, hydrogen fuel cell and battery vehicle manufacturers can install an ion exchange filter comprised of ion exchange resins that can withstand the extreme temperatures and operating conditions of the system.
The purification functionality of DuPont™ AmberLite™ EV2X resin is critical, helping to extend the life of the glycol coolant, coolant loop components, and the ion exchange filter. This optimized resin has been tested and validated under extreme conditions, up to 105°C for over 1,000 hours.
