(Green Car Reports) - Tesla has patented a wireless EV charging system, indicating that the company is preparing to commercialize tech that’s been hinting at for years as a possible addition to its electric vehicles. A patent filing was spotted by Twitter (now known as X) user SETI Park. It was filed by Tesla Feb. 2 and published by the World Intellectual Property Organization (WIPO) Sept. 6. It discusses a form of inductive charging, in which electricity is transmitted from a coil connected to a power source to one on an electric vehicle, that is the most common current method of wireless charging. Tesla first teased wireless charging during a March 2023 presentation to investors, showing what appeared to be a wireless charging pad beneath a garage-parked Model S in one presentation slide. Tesla did not comment on when or even if it would offer wireless charging to EV owners at the time, but just a few months later, enthusiast media noticed that the automaker appeared to have acquired German wireless charging firm Wiferion. Again, Tesla didn’t publicly comment on its acquisition of the Wiferion or any wireless charging plans that might enable.

For Tesla, wireless charging could also increase the uptime for self-driving vehicles, such as the revenue-generating robotaxis Tesla CEO Elon Musk continues to pursue.
