Wireless EV charging, also called inductive charging, transfers power from a pad on or in the parking surface to a receiver under the vehicle, with no cable or plug. The driver parks over the pad and charging begins.
In North America, SAE J2954 sets standards for wireless charging of light-duty vehicles, including power levels, alignment and interoperability. Efficiency close to plug-in charging has been demonstrated, but few production vehicles have receivers, so installations are mostly pilots, fleets and transit.
Where it fits
- Fleets and robotaxis. Vehicles that park themselves can charge without anyone plugging in. See autonomous valet parking.
- Taxi ranks and bus layovers. Short, repeated top-ups while vehicles wait.
- Accessibility. No heavy cable to handle.
- Vandalism and clutter. No cables to damage or trip over.
Considerations
Pads must be installed in the slab or surface with power to each space, alignment matters, and vehicle support is limited for now. Conduit placed during construction keeps the option open.
The Parkonomics view
Wireless charging pairs naturally with vehicles that park themselves. It is a technology to plan conduit for, rather than one to buy at scale today.
