"Tesla's wireless charging system is described as follows in the document: "The Tesla positioning system is an impulse UWB radio system that enables peer-to-peer communications between a UWB transceiver installed on an electric vehicle (EV) and a second UWB transceiver installed on a ground-level pad, which could be located outdoors, to achieve optimal positioning for the EV to charge wirelessly." The company explained that Bluetooth is first used to locate the charging pad."
"BREAKING: The FCC today officially granted @Tesla a waiver allowing it to use Ultra-Wideband (UWB) radio technology for its wireless EV charging system that will be used to wirelessly charge the Cybercab.Normally, this kind of radio must be handheld and can't be installed... pic.twitter.com/pve5NSoqtc- Sawyer Merritt (@SawyerMerritt) February 19, 2026 Once the vehicle approaches the pad, the UWB system briefly activates. "When the vehicle approaches the ground pad, the UWB transceivers will operate to track the position of the vehicle to determine when the optimal position has been achieved over the pad before enabling wireless power charging.""
FCC approval allows Tesla to use Ultra-Wideband (UWB) radio technology in a wireless EV charging system for the Cybercab, enabling installation on fixed outdoor ground pads. The system pairs an impulse UWB transceiver on the vehicle with a transceiver on a ground-level pad to achieve precise peer-to-peer positioning for wireless power transfer. Bluetooth is used initially for the vehicle to discover and exchange data with the pad, then UWB briefly activates as the vehicle approaches to track position and confirm optimal alignment before enabling charging. The waiver removes a regulatory constraint for the planned autonomous two-seater charging pad.
