QKOIL™ Expands Its Patent Portfolio With Two New Filings Covering the Future of Autonomous Charging Infrastructure
EV Charging Systems LLC (dba QKOIL™) has filed two new patent applications that mark a significant milestone in the company's growing intellectual property portfolio. These filings join a portfolio of patent applications filed and issued in the United States, together with international patent applications filed under the Patent Cooperation Treaty (PCT), collectively staking out QKOIL™'s foundational position in the emerging field of autonomous charging infrastructure.
The two new applications cover innovations that go well beyond the company's core overhead wireless charging platform. Together, they address the full-stack challenge of truly autonomous charging: not just delivering power contactlessly, but doing so intelligently, adaptively, and without any human involvement — at the scale that next-generation autonomous vehicle and robot fleets will demand.
What Is Overhead Autonomous Charging? Why Every Warehouse Robot Fleet Needs It
Overhead autonomous charging moves the entire charging apparatus up and off the floor. Rather than requiring a robot to navigate to a dedicated station, dock precisely, and sit idle, the power comes from above.
The QKOIL™ platform is a patented overhead wireless inductive charging system. Power-transmitting coils are mounted overhead, on ceiling infrastructure, gantries, or existing racking system, while each AMR carries a compact receiver coil on its upper surface. When a robot positions itself beneath an overhead unit, wireless power transfer begins automatically. No cables. No connectors. No human intervention.
This approach supports opportunity charging; the robot tops off its battery during any idle moment beneath the overhead unit rather than making a dedicated trip to a charging station. The result is near-continuous operation with dramatically reduced downtime.
