Powermat Technologies today unveiled a wireless charging solution designed for fleets of various types of service robots used for commercial cleaning, delivery, warehouse operations, medical operations, and more.

It develops wireless power technology based on magnetic induction, which is also known as inductive charging. Powermat’s wireless charging technology for commercial robots supports power transfer over a distance of up to 150 millimeters between receiver and transmitter.

Powermat said the system offers up to 300W of power. It said the system eliminates the need for direct contact with pogo-pins entirely, providing operators with 90% charging efficiency.

Powermat also offers turnkey reference designs for wireless charging and battery management. This ensures communication between each robot in a fleet and at docking stations, which is required for identification and authentication, software upgrades, and more.

“For organizations to get the most return on their investment in autonomous solutions, service robots should always be able to complete their task autonomously and recharge quickly without human intervention,” said Elad Dubzinski, CEO, Powermat.

Powermat Technologies in mid-December 2021 raised $25 million in Series B funding to scale its wireless charging technology. The round was led by Foxconn Interconnect Technology (FIT) and Hudson Sustainable Group, which is a founding shareholder of Powermat.

There are several other companies that develop wireless charging solutions for robots. Some of those companies include In2Power, Vicor, WiBotic, Wiferion.

Powermat said its charging solutions can also be found in more than 800 million smartphones, 40 million embedded accessories, and 8 million cars worldwide. Global market leaders, including FIT, Flex, General Motors, Harman International, Kyocera, and Samsung are already using Powermat’s Technology.
