Ocean Power Technologies Awarded Patent for System and Method for Vehicle Charging
The newly allowed patent (Application No. 18/936,528) protects OPT’s breakthrough system for an autonomous, floating marine charging solution. Designed to address the increasing demand for clean maritime operations, the invention enables electric vessels—including uncrewed surface vehicles—to safely locate, dock with, and recharge from a floating energy platform while at sea.
This innovation is core to OPT’s vision of scalable, intelligent offshore infrastructure. The floating charging station will integrate seamlessly with the PowerBuoy® platform, allowing it to serve as both a power generation node and a recharging hub. When combined, these systems will enable WAM-V® autonomous surface vehicles to conduct long-duration missions with minimized downtime and no need for shore return.
The patent covers multiple key features, including:
- Signal-emitting guidance systems for dynamic maritime docking.
- Flexible and secure mooring structures to stabilize vessels during energy transfer.
- Wired and wireless energy delivery mechanisms; and
- Options for wave-powered self-sustaining energy generation.
“This patent exemplifies the kind of transformative thinking that allows us to lead in offshore autonomy. By enabling persistent power-at-sea, we’re not only increasing the endurance of our WAM-V®s but also expanding what's possible for our defense, commercial, and scientific customers. This is another strong step in building a truly intelligent and resilient ocean infrastructure.”
With this patent, OPT strengthens its IP portfolio and expands its capacity to support clients operating in remote or infrastructure-limited marine environments. The solution provides a foundational capability for extending the range and autonomy of uncrewed maritime systems.
