Wireless EV Charging

Hyundai Motor Company, Toyota Motor Corporation, WiTricity and Electreon are among the companies working on wireless EV charging. Hyundai has disclosed a bidirectional power-transfer design, Toyota research addresses charging while driving, WiTricity develops wireless charging systems, and Electreon builds road-embedded infrastructure. BMW has also joined HEVO and Oak Ridge National Laboratory in an evaluation program.

WiTricity and Eleappower Ltd. are identified as startups working on wireless EV charging, but the available information does not establish a comparative ranking. WiTricity’s work includes resonant magnetic coupling and a Florida research and development laboratory. Eleappower’s work includes foreign-object detection and split-phase magnetic couplers that integrate wireless transfer with onboard charging.

SRM University, Fuzhou University and the University of Auckland are active research organizations in wireless EV charging. Their work includes renewable-powered charging for autonomous vehicles, adaptive receivers designed to improve interoperability, and thermal analysis of inductive charging pads. Recent work from Fuzhou University and Tsinghua University also examines reconfigurable charging topologies and interoperable coils.

Funding indicators list $50.5 million in grants across 25 awards since 2020, as well as 10 recorded funding rounds totaling $1.24 billion. These figures describe funding signals associated with the topic, not necessarily funding dedicated exclusively to wireless EV charging. The listed round entries include projects, grants and corporate financing, so they should not be treated as a single category of investment.

Hyundai Motor Company leads the listed patent holders with 20 patents, followed by LG Innotek Co. Ltd. with 16. WiTricity has 12 listed patents and Electreon has 11. Kia Motors and Kia Corporation each have 10 listed patents. These counts identify patent holders in the supplied topic data; they do not establish patent quality or freedom to operate.

No: the data records 151 patents in the 24-month window and a 47.5% decline in patent activity. Publications also declined, with 764 in the last year and growth of -7.8%. The overall activity growth figure is -42.1%. These signals indicate lower recent activity in the measured window, but do not by themselves show whether commercial deployment or technical progress is slowing.

Wireless EV charging has moved beyond laboratory research into consumer offerings and roadway testing, but deployment remains uneven across applications. Porsche brought inductive charging to a consumer offering in September 2026, while Honda’s October 2026 news described plans for in-road tests. Research continues to address interoperability, misalignment, thermal performance and control, indicating that practical integration remains an active engineering challenge.

The main approaches are stationary inductive pads, dynamic roadway systems, resonant magnetic coupling, capacitive power transfer, and power conversion and compensation. Stationary pads charge parked vehicles, while roadway systems aim to charge vehicles in motion. Resonant coupling transfers energy through magnetic fields; capacitive systems use electric fields. Conversion and compensation methods regulate system power and output rather than defining where charging occurs.

The listed applications include passenger vehicles, commercial fleets, public transit, public and workplace parking, and autonomous mobility. Passenger vehicles are the largest application category in the data, followed by commercial fleets and public transit. Wireless charging can support parked vehicles at homes or depots and, where roadway infrastructure is installed, vehicles charging while moving or waiting along a route.
