Powermat Technologies has launched a 600W wireless charging system for mid-power industrial, e-bikes, robotics, medical and telecom applications.

The technology also enables underwater charging in a soon-to-be-announced new pool cleaning robot.

The PMT350 600W SmartInductive hybrid inductive/resonance wireless power platform is a $100 reference design for cable-free, wirelessly-powered systems for industrial and other mid-power applications. This incudes full production files such as eBOM, schematics, integration support and system pre-certifications.

Last week the company teamed up with Powercast to combine wireless power technologies.

“Delivering the first affordable wireless power system designed for Industry 4.0 is a game changer for powerful systems that are notoriously expensive to implement,” said Kfir Abuhatzira, CEO of Powermat. “Industrial equipment often vibrates or moves, so replacing charging cables which can break or dislodge with wireless power technology eliminates the expensive downtime of both maintenance and wired charging to lower total cost of ownership.”

The PMT350 delivers total power of 600W with up to 58V input and output and up to 12.5A current. It also works with lower-power applications and can be configured in multi-module mode for applications requiring more than 600W.

The SmartInductive wireless power technology features embeddable software implemented on COTS hardware for maximum affordability.

A transmitter (Tx) sends energy wirelessly to a receiver (Rx) that converts it to power to directly power a device or recharge its batteries. SmartInductive combines the best of short-range inductive and resonance wireless charging to eliminate exact placement restrictions and provide freedom of alignment between the Tx and Rx charging coils up to eight inches. SmartInductive can penetrate eight inches of wall and windows, and beyond power transmission, can also transmit data between the coils to control edge devices.

The previous-generation 40W, 200W and 300W platforms have been installed in 28 models of car for wireless smartphone charging and are used for through-wall-and-window wireless charging to facilitate deployment of 5G repeaters, such as the Echo 5G developed with Pivotal Commware. In this system a wireless charger attaches inside the home or building while the 5G system attaches outside, creating a simple, consumer-installed system that eliminates expensive through-wall cabling and technician visits.
