During the show, researchers tested the Toyota RAV4, a 10kWh battery that can be fully charged in only 30 minutes and 80% in 18 minutes. Omer Onar, principal investigator at ORNL, said the length of charging time is related to the battery capacity of the vehicle.
It is understood that ORNL's next research goal is to charge the power up to 50kW wireless charging system, when the time, 10kWh battery can be fully filled in only 7 minutes, but also can be applied to trucks and buses and other models.
