The research team of Oak Ridge National Laboratory (ORNL) has made significant progress
in wireless charging technology for electric vehicles.
A 20-kilowatt wireless charging system with a charging efficiency of 90 percent, three times faster than plug-in electric vehicle devices commonly used, will help accelerate the widespread use
of electric vehicles.
According to the news on April 5, according to the Physicists Organization Network recently reported, Madou Chensawali, director of the power electronics team at Oak Ridge National Laboratory, said: "Over the years, we have made tremendous progress
from the laboratory proof of concept to now.
This technology is currently being integrated into some Toyota vehicles by combining physical engineering, design, and scale, in preparation
for bringing this technology closer to market needs.
”
The 20-kilowatt wireless charging system developed by the team in just three years for cars has a unique structure, including inverter power supply, isolation transformer and coupling technology for vehicle-side electronics
.
In the demonstration, the researchers integrated a separate converter system into a Toyota RAV4 electric vehicle with a 10 kWh battery for charging
.
Since higher power levels are essential for larger cars, such as trucks and buses, researchers are targeting 50-kilowatt wireless charging systems as their next endeavor, which will match the power levels of commercially available plug-in fast chargers to provide the same charging speed, or increase consumer acceptance of electric vehicles
.
Industry partners promoting the technology include Toyota, Cisco, Evatran and the International Automotive Research Center
at Clemson University.
The U.
S.
Office of Energy Efficiency and Renewable Energy Vehicle Technology provided partial funding for this competitive project in support of the Department of Energy's "Big Challenge for Electric Vehicles Everywhere"
initiative.
The aim is to make electric vehicles affordable, more convenient and cleaner for consumers by 2022
.
David Smith, Vehicle Systems Project Manager, said: "Compared to plug-in charging, wireless power transfer is a typical paradigm shift in the charging process of electric vehicles, providing consumers with an autonomous, safe, efficient and convenient choice
.
Today's technology shows that it will be a stepping stone
for vehicles to recharge while on the road and onto the path of electrification.
