Powermat Unveiled Through-walls Wireless Charging

Tel Aviv-based Powermat has launched a new mid-range wireless charging platform for mobile and IoT devices . The technology is based on electromagnetic induction and is capable of charging devices, as well as providing them with a continuous current of up to 50W over a distance of 20 cm, and also through walls, glass windows and plastic surfaces.

Previous generations provided shorter distances of 0.8-10 cm. Powermat product manager, Aya Kantor, told Techtime the increased range addresses the needs of the IoT devices. “Most wireless charging platforms require high coupling between the receiver and the transmitter'” he said. “But many devices are not able to achieve exact coupling, hence the need to expand the charging range.”

The new mid-range platform can wirelessly charge security cameras and 5G transmitters installed outside the house, without the need of through-wall cabling. It also ideal for home robots such as autonomous vacuum cleaners, which miss many time the needed position for a smooth charging process due to lack of precision.

Booming market

Powermat technology is based onelectromagnetic induction process, which creates an alternating electromagnetic field and transfers energy between a transmiter and the receiver, both of which contain an induction coil. When placed in close proximity to the transmitter, the receiver converts the electromagnetic field into electrical power. Using in-band signaling to communicate, the two units are able to regulate power levels and manage the charging.

Powermat is a pioneer of wireless charging and was the first to introduce wireless charging surfaces for smartphones. It was founded in 2006 by Ran Polyakin, Dr. Amir Ben Shalom, Dov Hirschberg and Yoav Hefer. The company has offices in Tel Aviv, Europe and the United States. It provides Qi-certified and proprietary wireless charging platforms for automotive, robotics, consumer electronics, medical devices, IoT, telecom, and Industrial applications.

The company’s inductive wireless charging technology can already be found in over 500 million devices and is deployed by global market leaders such as Samsung, LG, General Motors, Flex, Harman International and Kyocera. According to Allied Market Research, the wireless charging market will grow from $ 6.5 billion in 2018 to $ 49.3 billion by 2027, due to the proliferation of IoT devices and the increasing adoption of wireless charging  by mobile manufacturers. Kantor: “We will continue to increase the charging ranges.”
