“Ask This Old House,” one of my favorite TV shows, presented a wireless EV charger on this week’s episode. It works by magnetic induction. The segment starts at 15:21 in the video.
The portable version is already being sold outside the U.S. The manufacturer is working on a concrete-embedded unit which is flush with the ground which will be commercially available in a couple of years. They are hoping to convince auto manufacturers to place the receiver in the new cars. Currently, the EV has to be retrofit.
I can see this turning into a clash between wired and wireless chargers in the spread of charging stations around the U.S. Clearly, wireless is better but there are legacy EVs that require wires.
