HEVO Inc. has received U.S. Patent No. 12,700,758 B2, titled “Systems and methods for dynamic roadway charging,” covering wireless power transfer to electric vehicles while they are in motion. The Brooklyn, New York-based company, which supplies Rezonant wireless charging hardware and the Journey software platform, filed the application on October 17, 2022. The claims describe a series of charging pads positioned along a roadway, each functioning as a transmitter to a receiver mounted on a passing vehicle.
Highlights
- U.S. Patent No. 12,700,758 B2 covers continuous wireless charging of electric vehicles traveling along a roadway
- Filed October 17, 2022, claiming priority to a provisional application filed October 18, 2021
- Five inventors named, all of Brooklyn, New York; the patent is assigned to HEVO Inc.
- Claims include bidirectional power flow, allowing vehicles to return stored energy to roadway infrastructure or the grid
How Does the System Deliver Power to a Moving Vehicle?
The patent describes a plurality of wireless charging pads installed along a roadway. Each pad defines a transmitter configured to wirelessly transfer electrical power to a receiver on one or more electric vehicles as those vehicles travel relative to the roadway.
A power station sited adjacent to the roadway and communicatively coupled to the pads contains an inverter that moves electrical power from a power source to the pads. According to the filing, the pads are collectively configured so that vehicle receivers receive power continuously as vehicles move along the roadway, rather than in discrete bursts tied to individual pad positions.
Bidirectional Flow and Pad Construction
Two further aspects of the claimed technology extend beyond the basic transmit-receive arrangement. Adjacent charging pads can wirelessly transfer power between one another, and the system supports bidirectional power flow — enabling both vehicle charging and the return of stored energy from vehicles to the roadway infrastructure or the grid.
The patent also addresses layered pad constructions that incorporate cabling, magnetic, power electronics and cooling elements. Integration options covered in the filing include fixed power stations, mobile charging depots, and rechargeable batteries positioned adjacent to the roadway.
Who Is Named on the Filing
Inventors listed on the patent are Jeremy McCool, Umer Anwer, Kerim Colak, Kunal Kamle and Luke Mansfield, all of Brooklyn, New York. The patent was assigned to HEVO Inc.
Where It Fits in HEVO’s Portfolio
HEVO says the dynamic system is designed to complement its existing UL-certified and SAE-qualified stationary wireless charging systems. The company identifies fleet operators, logistics providers, OEMs and roadway infrastructure programs as target applications, building on commercial work that includes a fleet electrification partnership in Saudi Arabia and an autonomous vehicle charging platform developed with Beam Global.
Founder and CEO Jeremy McCool framed the grant as an extension of the company’s existing intellectual property position.
“This patent issuance represents an important expansion of HEVO’s intellectual property portfolio in dynamic wireless charging,” McCool said. “The ability to deliver continuous power to electric and autonomous vehicles while they are in motion is fundamental to reducing range anxiety, improving fleet utilization and enabling the next generation of automated mobility. This technology strengthens the foundation of our Rezonant™ hardware and Journey™ platform as we advance commercial deployments of both stationary and in-road wireless charging solutions.”
