According to New Atlas, recently, the Oak Ridge National Laboratory (ORNL) in Tennessee, USA, conducted a breakthrough research, demonstrating the fastest and most powerful car wireless charging to date. technology.
The team has developed a wireless charging pad using a lightweight polyphase electromagnetic coupling coil design that it claims can deliver power to electric vehicles at an output of up to 100 kilowatts. The receiving coil is mounted on the bottom of a Hyundai Kona electric vehicle, which is parked above a 14-inch diameter polyphase transmitter with a 5-inch gap in between.
Omer Onar, an engineer on the team, said the team has achieved the world’s highest power density for such a car wireless charging system. “Our technology achieves a power density that is 8-10 times that of traditional coil technology, and can increase the battery state of charge by 50% in 20 minutes… This is a breakthrough achievement, providing fast and efficient wireless charging for passenger electric vehicles. Charging opens doors.”
The current situation is that wireless vehicle charging technology has not really taken off in the electric vehicle field because its power levels are far from the fast charging requirements. One of the fastest electric vehicle wireless charging facilities out there is Hevo’s 12kW “jobbie,” according to Verified Market Reports. According to the report, the new solution disclosed by Oak Ridge National Laboratory appears to be “very promising” because of this.
