Ford is trying to patent a strategy to make wi-fi EV charging simpler.

Wi-fi charging techniques exist already, albeit largely in aftermarket type. Nevertheless Ford’s patent utility, which was revealed by the US 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 techniques use electromagnetic fields that switch vitality from an influence supply to a receiver on the car and not using a bodily connection. This vitality switch may 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 that will interrupt charging, and warn the driving 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 “could cut back or get rid of inadvertent triggering of an related decreased energy mode of shutdown of the charging system” if objects that would probably block the transfers of vitality between a wi-fi charger and receiver are detected, in line with the appliance. However that is probably not the principle subject holding again wi-fi charging.

Eliminating cumbersome cables makes wi-fi charging extra handy, and WiTricity, one of many main aftermarket wireless-charging corporations, has mentioned its tech can match the effectivity and energy output of most AC plug-in charging {hardware}. The prohibiting issue to widespread adoption is price—one thing Ford would not handle right here.
