Ford patents wi-fi EV charging system
Ford is trying to patent a strategy to make wi-fi EV charging more practical.
Wi-fi charging techniques exist already, albeit principally in aftermarket kind. Nonetheless Ford’s patent software, which was revealed by america 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 software, most wi-fi EV charging techniques use electromagnetic fields that switch power from an influence supply to a receiver on the automobile with out a bodily connection. This power switch might be interrupted if any objects—notably these containing steel—are in shut proximity to the charging {hardware}.
The answer outlined within the patent software 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 might make use of cameras, lights, and audio system put in on a automobile, which might be networked to the charger, Ford famous within the software.

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 would doubtlessly block the transfers of power between a wi-fi charger and receiver are detected, in line with the applying. However that will not be the primary problem 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 said 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 deal with right here.
