REASONANCE

Q&A

We are a group of Russian scientists and engineers working together in a private R&D company. We have developed a brand new wireless energy transfer technology.

Our product is a cost effective and scalable solution that allows transferring energy without using any wires in a much more efficient way as compared to the other technologies on the market.

We do not plan to manufacture or sell any finished commercial products. Instead, we provide access to Reasonance technology for potential industrial partners for use in their products, thus significantly improving the products’ efficiency, usability and market potential.

Resonance phenomena are well-researched and documented. In this sense, we are similar to our competitors. The fundamental difference being in the design of the transmitting and receiving systems, which makes it possible for REASONANCE to significantly increase efficiency and decrease costs.

The simplicity and efficiency of the REASONANCE design allows to achieve the same wireless energy transfer (WET) results as its competitors whilst reducing costs by 80-90% (5-10 times cheaper).

REASONANCE also uses significantly lower frequencies thereby reducing the effect of electromagnetic fields on living beings.

Currently, the main WET solutions fall into these 2 groups:

a) Inductance or capacitance method, transferring energy for up to 5 cm.
b) Magnetic resonance, transferring energy for up to 20 cm.

REASONANCE technology goes further: resonant  inductance and capacitance solutions are combined in a single package and a magnetic field is generated by both conductivity and displacement currents. Competitors generate a magnetic field only by conductivity currents.

We have designed the coils to create multiple resonant circuits in one resonant contour and combine inductance and capacitance in a single structural element. These remarkable characteristics of wireless energy transfer cannot be achieved by competitive technologies.

REASONANCE complies with SAE J2954 standard for wireless charging of e-vehicles.

 

REASONANCE technology also allows for the transfer up to 10 kW of power at frequencies less than 85 kHz at 95% efficiency and with an air gap of up to 1 meter. However, we are constantly developing the technology and intend to increase the power transfer up to 300 kW with the same efficiency.

The technology uses electromagnetic fields with frequency ranges lower than 85 kHZ and is therefore perfectly safe. These parameters are in full compliance with the international standards for public exposure limits set by International Commission on Non-Ionizing Radiation Protection, ICNRIP – https://www.who.int/peh-emf/about/WhatisEMF/en/index4.html.

Nonetheless, we actively strive to decrease the frequency (unlike our competitors), using the WHO recommendations on safety as a point of reference, which state that frequencies below 30 kHz have no adverse effects on living beings.

The REASONANCE technology is very flexible when it comes to placing transmitting and receiving modules. Specifically, shifting the receiving coil from the center line by half a diameter with angles up to 90 degrees can maintain efficiency at 95-97%. Compared with other technologies on the market, the change in efficiency in such cases is negligible.

No, particularly when compared to other technologies on the market. REASONANCE technology does not require any complex engineering solutions for positioning; it does not use any magnets or any other devices except for some simple generators and coils patented by our company. 

Following the SAE J2954 standard reduces the costs of REASONANCE solutions by 80-90% (5-10 times cheaper). This is achieved through simplicity and availability of the materials used in REASONANCE coils.

The coils use standard wire; basically that’s all. The coil configuration, on the other hand, is our technical know-how. 

We are currently choosing an industrial partner in order to demonstrate the advantages of REASONANCE technology in real-world market applications and products, and are negotiating with a number of European auto manufacturers and design bureaus. 

Technologically, we are ready to implement REASONANCE solutions in a real product. We have numerous laboratory stands that demonstrate wireless energy transfer for various distances (up to 1 meter and more).

Possible applications are limited only by your imagination. Think about your house. Everything that is plugged can be unplugged – the e-car or bike in your garage, the mobile phone in your pocket, the TV on your wall, or the kettle in your kitchen – all can be charged wirelessly. Same applies to industrial settings: e-forklifts in warehouses, e-trucks, drones and many more. Real-world applications are limitless. Literally, any device that relies on electrical power and wires can be charged wirelessly.

Wireless energy transfer is a natural technological development. WET is better, safer and cheaper, and may be the last obstacle towards achieving a breakthrough in autonomous technologies (unmanned vehicles, for instance).

Yes, we have patents granted by the Russian Patent Office. Priority applications have also been filed in the USA, EU, China, India, Canada, and Korea. The patent title is “Method and device for wireless charging of electrical energy storage in a fixed or mobile consumer”. Please refer to https://patents.google.com/patent/US20190319490A1.

REASONANCE technology complies with SAE J2954 which is the existing standard for wireless power transfer for electric vehicles. However, we foresee that in time a new wireless energy transfer standard may be formulated on the basis of REASONANCE technology.
