Introduction to Wireless Power

Ever seen over the air wireless power in action?

The demo video above demonstrates what the future of power looks like. For some of our partners this future is already the present.

Each Lego train in the video represents an electronic device that can be powered wirelessly, whether it is static or in motion.

In your home it can be a smartphone, an Xbox controller or a smart lock. It can be a digital display at the edge of a supermarket shelf, a vibration sensor on an industrial production floor, or a smart door lock in a hotel hallway. It can be anywhere you need to power devices at a distance, over the air, safely and without user intervention.

3 merits of a successful wireless power solution

Power | Wi-Charge delivers more usable power over distance than any other approach, even enough to safely charge a smartphone.

Distance | We power devices at room-sized distances and beyond. Power is the same regardless of distance, unlike other technologies whose power drops as a function of the distance squared.

Safety | Certified as safe for consumers in any and all usage scenarios. Delivers power only to the target device and does not bathe the environment with unwanted radiation. 

Only Wi-Charge's patented technology meets these requirements, enabling over the air wireless power to thumb-size receivers that can be embedded in different electronic devices. The different Wi-Charge transmitters supports charging of multiple receivers, smartly dividing the total energy among charged devices. 

How does it work?

Wireless Power Transmitter

  • Plugged to the mains (AC or DC)

  • Converts electricity into safe infrared beams

  • Automatically identifies client devices

  • Delivers infrared energy to client devices

Wireless Power Receiver

  • Plugged to or embedded in a client device

  • Receiver converts IR to electricity

  • Receiver charges an internal rechargeable battery or a super-capacitor which the client device uses

  • The receiver sends back client device telemetry including battery status, usage stats, billing info etc.

System Block Diagram

  • One or more devices are powered simultaneously

  • Power is distributed intelligently between client devices based on their needs

  • Data is collected from each device

Advanced Topologies

Wi-Commercial and public spaces are likely to use multiple transmitters to power many client devices in large halls. Supermarkets, production floors, shopping centers and restaurants have tens of smart devices to power.

For these types of deployments Wi-Charge offers a complete wireless power grid network solution.

The different Wi-Charge transmitters communicate through a cloud server, allocating power to the different devices based on their power requirements, battery level, power availability, customer-set priority level and other considerations. Smart AI algorithms make sure all devices enjoy endless battery-life.

The network owner has access to dashboards and a control interface to easily monitor and manage the wireless power service in one or many sites. Custom logic can be added to fit the customer's business intelligence (BI) and control requirements.
