Provides simultaneous charging on all sides of the device to reduce charging time.
Wireless charging of electronic products such as mobile devices is an area of significant interest and research. Unfortunately, challenges have stunted the growth of the wireless charging industry. For example, many so-called “wireless” charging solutions are not yet entirely wireless. They tend to be slow and less energy efficient than (for example) simply plugging your phone in. They usually have significant limitations in terms of position and distance of the device relative to the charging system. These and numerous other challenges have resulted in the electronic device industry actively seeking new and better performing options for wireless charging.
This technology is a wireless charger system that incorporates coupled magnetic resonance and is capable of powering devices at distances of a few centimeters to 1 meter, with a wide power range of a few watts up to a 1000 watts. It consists of a wireless transmitter, a receiver operating at KHz, MHz, GHz and/or higher frequencies, a power driver for the transmitter, and an AC to DC power converter at the receiver unit. This technology provides a stable 95% and 86.5% efficiency at 5 cm and 10 cm distances, respectively. By increasing the diameter of the transmitter, devices can be charged up to 100 cm. Further, the efficiency is significantly improved by tuning the transmitter and receiver at each transfer distance in real time.
• Less degradation in power efficiency with range.
• Can charge multiple devices on both sides of the transmitter.
• Allows for thin flexible receivers that can be mounted on planar, singly and doubly curved surfaces.
• Electric vehicles.
• Land, air, and sea vehicles (autonomous and non-autonomous).
• Commercial and military air vehicles, drones, micro air vehicles.
• Cars, SUVs, minivans, and other vehicles.
• Motor bikes.
• Sensors and devices related to the Industrial Internet of Things.
