Researchers at Oak Ridge National Laboratory shared their intriguing studies of wireless charging and seawater batteries, among other novel projects, with U.S. Energy Secretary Jennifer Granholm during a tour on Monday.

Granholm was in East Tennessee to highlight the bipartisan infrastructure bill, which passed Congress and was signed into law by President Joe Biden on November 15, and the president’s Build Back Better agenda, which passed the U.S. House of Representatives last week but hasn’t been approved by the Senate yet.

“These historic investments will accelerate the transition to a more resilient, clean energy powered future—bringing economic development and good-paying, local jobs,” the U.S. Department of Energy said in a press release.

The Biden administration has set a goal of reducing greenhouse gas emissions by 50 percent, compared to 2005 levels, by 2030 and reaching net zero emissions by 2050.

“Part of the legislation passed last week is a big step forward,” Granholm said.

Among other benefits, the ORNL projects are expected to help the United States transition to a carbon-free economy as countries around the world seek to reduce emissions, improve the use of batteries and renewable energy, and allow the nation to be less reliant on other countries for critical materials such as cobalt.

Researchers at Oak Ridge National Laboratory have demonstrated a 120-kilowatt wireless charging system for vehicles—providing six times the power of previous ORNL technology and a big step toward charging times that rival the speed and convenience of a gas station fill-up.

The wireless system transfers 120 kilowatts of power with 97 percent efficiency, which is comparable to conventional, wired high-power fast chargers. In the laboratory demonstration, power was transferred across a six-inch air gap between two magnetic coils and charged a battery pack.

ORNL researchers created and demonstrated the world’s first 20-kilowatt wireless charging system, which is being modified for applications such as commercial delivery trucks.

“It was important to maintain the same or smaller footprint as the previous demonstration to encourage commercial adoption,” said project lead Veda Galigekere of ORNL’s Power Electronics and Electric Machinery Group. [Read more…]

A 20-kilowatt wireless charging system demonstrated at the U.S. Department of Energy’s Oak Ridge National Laboratory has achieved 90 percent efficiency and at three times the rate of the plug-in systems commonly used for electric vehicles today.

This ability can help accelerate the adoption and convenience of electric vehicles. Industry partners from Toyota, Cisco Systems, Evatran, and Clemson University International Center for Automotive Research contributed to the technology development demonstrated today at ORNL.

“We have made tremendous progress from the lab proof-of-concept experiments a few years ago,” said Madhu Chinthavali, ORNL Power Electronics Team lead. “We have set a path forward that started with solid engineering, design, scale-up, and integration into several Toyota vehicles. We now have a technology that is moving closer to being ready for the market.” [Read more…]

What if charging your plug-in electric vehicle was as easy as parking it? No need for cords or cards. Just as Wi-Fi has freed consumers of wires when accessing the Internet, wireless charging technology may soon be as widespread, thanks to research supported by the U.S. Department of Energy.

With support from the Vehicle Technologies Office, Oak Ridge National Laboratory and Hyundai America Technical Center Inc. have been working since 2012 to demonstrate wireless charging on a variety of vehicles. ORNL is working with a mix of Toyota vehicles, including models of the all-electric RAV 4, plug-in hybrid electric Prius, and all-electric Scion iQ, while Hyundai America Technical Center Inc. is testing its technology on five all-electric Kia Souls.

The technology behind wireless charging creates a connection between a transmitting pad on the ground (such as in a garage) and a receiving pad integrated on the bottom of the vehicle. In the projects ORNL is leading, the transmitting pad is connected to a 240-volt outlet and generates a magnetic field of a certain frequency. When the coil in the receiving pad is tuned to oscillate at the same frequency, the magnetic field will generate a current in the receiving coil, charging the vehicle’s battery. [Read more…]
