Researchers at Oak Ridge National Laboratory (ORNL) have achieved a world record by successfully demonstrating a 270-kilowatt wireless power transfer system for light-duty electric vehicles, specifically using a Porsche Taycan. This advancement, developed in collaboration with Volkswagen Group of America, surpasses ORNL's previous 100-kW wireless charging demonstration. The innovative polyphase wireless charging system utilizes lightweight electromagnetic coupling coils, allowing for high power density in a compact design. This technology is crucial for electric vehicles, which face limitations in accommodating conventional heavy charging systems.
The system can increase the vehicle's state of charge by 50% in just 10 minutes with over 95% efficiency, operating over a 4.75-inch gap. The project, funded by the Department of Energy, aims to enhance the adoption of electric vehicles by making charging faster and more convenient. ORNL plans to further develop this technology into a cost-effective and manufacturable system, with potential applications for residential charging and even charging vehicles in motion.
The achievement aligns with DOE's goal of extreme fast-charging, targeting systems that deliver 250 to 300 kilowatts to reduce charging times significantly. ORNL's ongoing research seeks to improve wireless charging capabilities for various vehicle types, including heavy-duty trucks, ultimately facilitating a more sustainable transportation sector.
