Frequently Asked Questions (FAQs)
What is the QKOIL system?
QKOIL is an overhead wireless charging platform designed to deliver power to electric mobility systems without cables, plugs, or floor-mounted pads. Instead of placing charging hardware on the ground, QKOIL positions the transmitter above the vehicle or device—creating a safer, cleaner, and more scalable charging environment.
The system is engineered to support:
Electric vehicles (EVs)
Autonomous vehicles (AVs)
Autonomous mobile robots (AMRs)
Automated guided vehicles (AGVs)
Warehouse and logistics robots
Fleet-based mobility systems
By moving charging infrastructure overhead, QKOIL transforms how energy is delivered in commercial, industrial, and smart mobility environments.
How does QKOIL work?
QKOIL uses inductive wireless power transfer technology to transmit energy from above the vehicle or device.
Here’s the process:
Overhead Transmitter Installation
A transmitter coil is mounted on a ceiling structure or supported by a gantry system. (Importantly, the transmitter is supported overhead and does not require floor embedding.)Vehicle-Mounted Receiver
Each vehicle or robot is equipped with a receiver coil located on its upper surface.Automatic Detection and Alignment
When a vehicle enters the charging zone, the system detects its presence and confirms proper positioning.Wireless Energy Transfer
Once alignment is verified, energy transfers inductively from the transmitter to the receiver—no physical contact required.Smart Charging Control
Charging begins automatically and can be managed sequentially or by priority, depending on fleet needs.
The result is seamless, hands-free charging that integrates naturally into automated workflows.
What are the advantages of overhead wireless charging?
Hands-Free Automation
Vehicles simply park beneath the transmitter and begin charging automatically. There are no cables to connect, no plugs to handle, and no human intervention required.
Ideal for Autonomous Systems
QKOIL is purpose-built for next-generation mobility ecosystems. It pairs naturally with autonomous fleets—such as those operated by companies like Waymo and Zoox—where eliminating human interaction is essential for efficiency and scalability.
It is equally valuable for warehouse AMRs and AGVs operating in continuous, high-cycle environments.
Space Efficiency
Floor space is premium space—especially in:
Fulfillment centers
Parking garages
Manufacturing facilities
Logistics hubs
Commercial depots
By relocating charging hardware overhead, QKOIL preserves ground-level real estate for traffic flow, storage, and operations. This improves safety and maximizes facility utilization.
Reduced Wear and Maintenance
Traditional plug-in systems suffer from cable fatigue, connector degradation, and physical damage. Floor pads can accumulate debris and require periodic servicing.
QKOIL’s contactless architecture removes mechanical connection points entirely. Fewer moving parts mean:
Reduced maintenance
Longer system life
Lower total cost of ownership
Sequential or Priority-Based Charging
Unlike conventional one-vehicle-per-charger setups, QKOIL supports fleet-based energy management. Multiple vehicles can charge sequentially or based on battery priority levels using shared overhead infrastructure—reducing installation complexity and capital expenditure.
Is QKOIL safe?
Yes. Safety is foundational to the system’s design.
QKOIL incorporates multiple layers of protection:
Automatic shutoff when no receiver is detected
Intelligent alignment verification before power transfer
Controlled electromagnetic fields with low leakage outside the charging zone
No exposed cables or metal contacts, reducing shock and trip hazards
These features make QKOIL particularly well-suited for high-traffic environments such as warehouses, logistics centers, and public mobility hubs.
Who can benefit from QKOIL?
QKOIL is designed for organizations and operators preparing for the future of electric and autonomous mobility.
EV Owners and Fleet Operators
Commercial fleets, delivery services, and shared mobility providers can streamline charging while reducing infrastructure clutter.
Autonomous Vehicle Operators
Self-driving taxi networks and autonomous delivery fleets benefit from fully automated, no-touch charging—removing a key operational bottleneck.
Warehouse and Logistics Providers
Facilities using AMRs or AGVs gain continuous uptime with minimal human intervention, improving productivity and safety.
Smart Building and Facility Managers
Developers and operators looking to future-proof infrastructure can integrate overhead charging into new construction or retrofit projects—creating scalable, space-efficient EV readiness.
What makes QKOIL different from floor- or ground-based charging systems?
Unlike traditional floor-mounted charging pads or plug-in systems that require precise vehicle positioning and often serve only one unit at a time, QKOIL’s overhead wireless charging architecture is designed for flexibility, scalability, and operational efficiency.
Here’s how QKOIL stands apart:
Easier Alignment for Modern Fleets
Floor-based charging pads typically demand tight parking tolerances. Vehicles must align directly over embedded pads, which can slow down operations and introduce inefficiencies—especially in autonomous environments.
QKOIL’s overhead system provides greater positional flexibility. Autonomous vehicles, automated guided vehicles (AGVs), forklifts, and mobile robots can position themselves beneath the transmitter with more tolerance and less operational friction. This makes QKOIL particularly well-suited for smart warehouses and Industry 4.0 facilities where continuous motion and automation are key.
Truly Hands-Free Operation
Traditional plug-in charging requires manual intervention—connecting cables, monitoring charge status, and unplugging when complete. Even floor-pad systems may require operator verification of alignment.
QKOIL eliminates physical connectors altogether. With no cables to plug in or remove, charging becomes fully hands-free and automated. This reduces labor demands, eliminates connector damage, and enhances safety by removing tripping hazards and exposed electrical hardware.
Supports Multiple Devices with Less Infrastructure
Most ground-based charging systems are designed for one-to-one charging—one pad per vehicle.
QKOIL is engineered to support fleet-based operations. Its overhead architecture enables sequential or priority-based charging, meaning multiple vehicles or devices can be serviced using the same infrastructure. Facilities can charge more units with fewer installed components, reducing capital expenditures and simplifying layout planning.
Clear Floor Space for Safer, More Efficient Operations
Warehouse and manufacturing floors are high-value real estate. Floor-mounted pads, cable runs, and charging stations consume usable space and can disrupt traffic flow.
By relocating charging hardware overhead, QKOIL frees up critical floor area. This improves:
Safety (fewer obstacles and tripping hazards)
Traffic flow for forklifts and mobile robots
Layout flexibility for production lines
Overall operational efficiency
In environments where every square foot matters, keeping the floor clear delivers measurable advantages.
Reduced Wear and Maintenance
Plug-in connectors and floor-mounted pads are subject to physical wear, contamination, and mechanical stress. Over time, cables fray, connectors degrade, and embedded pads require service.
QKOIL’s contactless design minimizes mechanical wear and eliminates exposed connection points. With fewer moving parts and no physical coupling, maintenance requirements are reduced and system longevity is extended—leading to lower total cost of ownership.
