Production advantages are possible due to good shear thinning behavior that allows for fast dispensing needed to support high-volume production. Handling also is improved by placement of the bonded battery in the floor of the passenger compartment, creating a low center of gravity.” With a quieter-running electric drivetrain, the vibration inhibition properties of BETAFORCE™ 2800 TC were also important for user satisfaction. The new 95kWh Audi e-tron battery – optimized with BETAFORCE™ 2800 TC that conducts temperature both during charging and driving – delivers a range of more than 400 kilometers and supports super-fast 150kW charging, freeing drivers from “range anxiety.” Audi’s e-tron SUV needed to be capable of super-fast charging without generating excessive heat. Audi’s goal was to ensure sufficient day-to-day capability without sacrificing performance.ĭrivers don’t want delays because their EV takes too long to charge. Some drivers resist adopting EVs because of limited driving range, performance, and battery life. Battery components must operate in the optimum temperature window of 25☌ during operations and below 60☌ while charging. One of the biggest challenges in designing batteries for plug-in hybrid (PH) and electrical vehicles (EV) is thermal management of the battery pack. In addition to thermal management capabilities, the thermal-conductive adhesive also was optimized to help attain best-in-class driving range, lengthen module lifecycle, and improve performance. BETAFORCE™ 2800 TC thermal-conductive two-component adhesives were optimized for the Audi e-tron.ĭuPont collaborated with Audi engineers to develop a bonding material that could support super-fast charging for the Audi e-tron, Audi’s first all-electric sport utility vehicle (SUV).
