Ford is seeking to patent a approach to make wi-fi EV charging simpler.
Wi-fi charging programs exist already, albeit principally in aftermarket kind. Nevertheless Ford’s patent utility, which was printed by the USA Patent and Trademark Workplace (USPTO) on June 1 (and initially filed on Nov. 30, 2021) particulars some potential enhancements.

As Ford notes within the patent utility, most wi-fi EV charging programs use electromagnetic fields that switch power from an influence supply to a receiver on the car and not using a bodily connection. This power switch might be interrupted if any objects—notably these containing metallic—are in shut proximity to the charging {hardware}.
The answer outlined within the patent utility is to make use of cameras to identify any objects which will interrupt charging, and warn the motive force with flashing lights or noises. Such an answer may make use of cameras, lights, and audio system put in on a car, which might be networked to the charger, Ford famous within the utility.

A warning system like this “might cut back or eradicate inadvertent triggering of an related lowered energy mode of shutdown of the charging system” if objects that might doubtlessly block the transfers of power between a wi-fi charger and receiver are detected, in response to the applying. However that is probably not the principle concern holding again wi-fi charging.
Eliminating cumbersome cables makes wi-fi charging extra handy, and WiTricity, one of many main aftermarket wireless-charging firms, has stated its tech can match the effectivity and energy output of most AC plug-in charging {hardware}. The prohibiting issue to widespread adoption is value—one thing Ford does not tackle right here.
