Investing in WiTricity

How Wireless Charging Works

  • Q: How has WiTricity pioneered magnetic resonance?

    WiTricity has developed systems/devices that use Magnetic Resonance to couple energy through oscillating magnetic fields. Resonant coupling occurs when the operating frequencies of the two systems – a transmitter and a receiver — are approximately the same. WiTricity powered transmitters and receivers are specially designed magnetic resonators that efficiently transfer power over distance via the magnetic near-field.

  • Q: What are the advantages of magnetic resonance?

    Magnetic Resonance delivers wireless power over distance, without compromise, from milliwatts to kilowatts. There are 4 major advantages:
    Spatial Freedom
    Multiple devices powered by single source
    Powers through surfaces
    Scalable power transfer

  • Q: What sets WiTricity apart in wireless charging?

    WiTricity is the acknowledged leader in magnetic resonance with a 14-year history in designing Magnetic Resonance systems and has unmatched magnetic & power electronics system designs. WiTricity holds the foundational patents for highly resonant wireless power transfer, with over 1,200 issued patents and over 500 pending patent applications.

  • Q: How does WiTricity’s technology differ from inductive/Qi?

    Inductive charging technology like that used in the Qi standard requires the transmitter and receiver to be in close contact and with perfect spatial alignment.

    Magnetic Resonant charging allows power transfer over distance with greater spatial freedom, allowing multiple devices to be charged simultaneously – through surfaces, at different power levels.

  • Q: How does WiTricity technology differ from radiative power transfer?

    Radiative refers to solutions that radiate energy, like WiFi or cell phones, into a broad space with a receiver that captures a small fraction of the input energy to power a device. Some radiative products have been proposed, but are generally limited to delivering hundreds of milliwatts.

  • Q: How does WiTricity technology differ from magnetic resonance imaging (MRI)?

    Many people assume that Magnetic Resonance must be similar to magnetic resonance imaging (MRI) technology. However, the technologies are similar in name only. MRI is, as its name suggests, a technology for using magnetism as a basis for diagnostic imaging of soft tissue in the human body. The “resonance” referred to in “MRI” refers to the resonance of atomic structures.

  • Q: How much power can be transferred?

    The technology scales from miliwatts to megawatts. Our industrial licensee partners provide 1kw- 3kw-30kw wireless charging systems, while EV licensee partners provide 3kw, 6kw, 11kw systems. WiTricity’s wireless charging products can scale up to 450kw.

  • Q: How efficient is WiTricity technology?

    The power transfer efficiency of a WiTricity solution depends on the relative sizes of the power transmitters and receivers, tuning of the solution for a specific distance between transmitters and receivers, and the desired power level. Electric vehicle wireless charging is as efficient as conventional plug-in, seeing results of 90-93%, grid to battery.

  • Q: How well does WiTricity technology work in the presence of metal?

    Electromagnetic (EM) fields do not generally pass through highly conducting materials, like many metals. As a result, metals such as aluminum or copper are sometimes used a shielding materials in wireless power transfer. However, EM fields can penetrate holes and slots in metals. If you have an object, for example a metal back smartphone, we can engineer a magnetic resonance system to transfer power to the device.
