Lab Demos First Wireless Charging System For Electric Cars

The Department of Energy’s Oak Ridge National Laboratory have created a wireless charging system for electric cars just as fast and efficient as wired chargers.

The wireless system works by taking energy from the grid and converting it into high-frequency alternating current, which in turn creates a magnetic field that can transmit energy across an air gap.

This breakthrough significantly advances the technology needed to encourage greater adoption of electric vehicles by increasing their range and the ease of recharging, and in turn supports an energy-efficient mobility system for the nation’s economic success,” said Moe Khaleel, associate laboratory director for Energy and Environmental Sciences at ORNL.

Wireless charging promises to make charging up an EV just as simple as filling up your combustion engine car at a corner gas station.
