Wireless EV charging hits 95% efficiency, lets cars power grids and charge on the go

University of Stuttgart researchers led by Nejila Parspour report a major step forward in wireless EV charging efficiency.

Their inductive power transfer system reached 95% efficiency for stationary charging and over 90% for moving applications.

The technology could enable charging while parked or driving, automatic grid connection, and bidirectional power flow.

Beyond EVs, the approach may also benefit autonomous vehicles, industrial robots, and medical devices.
