Efficiency in Wireless EV Charging with QKOIL
EV Charging Solutions, LLC is redefining EV charging with the QKOIL above-the-vehicle wireless system. This innovative setup features a gantry-mounted charging apparatus that moves seamlessly across the ceiling, positioning itself directly above any parked EV within a multi-vehicle space. The apparatus operates along three axes (x, y, z) to automatically align a charge-transmitting device over a vehicle's receiving coil, which may be integrated into the car’s surface or discreetly placed on areas like the hood, frunk, or roof.
Once in alignment, the QKOIL system initiates wireless electromagnetic charging, with the device retracting to service the next vehicle after a full charge. This hands-free, automated process is ideal for high-traffic environments like parking garages, fleet charging stations, hotels, apartments, and multi-family housing complexes.
Addressing Efficiency in Wireless EV Charging
A common misconception about wireless EV charging is that it’s inefficient compared to wired charging. However, research led by the Department of Energy’s Oak Ridge National Laboratory (ORNL) shows that wireless EV charging can achieve high levels of efficiency, rivaling wired methods. ORNL researchers have demonstrated that custom-designed magnetic coils, silicon carbide-based power electronics, and advanced control systems can transfer power at greater than 92% efficiency for a light-duty car over a six-inch air gap and for a medium-duty truck over an 11-inch gap, both at 20-kilowatt levels. The ORNL breakthrough even achieved a 120-kW wireless charging system with an impressive 97% efficiency, showing that wireless can indeed match wired systems in efficiency.
The QKOIL Advantage
The QKOIL system builds on these industry advancements by employing a ceiling-mounted, above-the-vehicle approach to wireless charging. This design not only minimizes spatial constraints but also streamlines vehicle alignment, ensuring an optimized transfer of energy. As technology progresses, we foresee wireless charging becoming increasingly attractive, as innovations in efficiency, safety, and functionality continue to expand.
