Black & Decker Invests in Wireless Charging Startup
13 June, 2018
Humavox from Israel has developed new wireless charging technology based on the principles of RF resonance. The company is raising now $10 million with the help of B & D
Stanley Black & Decker is leading the $10 million funding round for the Tel Aviv based Humavox, inventor of a new wireless charging technology. Humavox technology enables everyday objects can turn into “hidden chargers,” including anything from car cup holders and gym bags, and more. The company’s technology uses near-field radio frequency (RF) charging to transform any of such “storage instrument/device/object” into a charger, so that users can keep using their portable electronics fully powered.
With its ETERNA platform, Humavox uses near-field radio frequency (RF) technology, and provides users with a simple and intuitive charging experience (“drop & charge”). The technology can be implemented in the smallest of devices, such as hearables, wearables and IoT devices. Humavox was founded in 2010 by Omri Lachman (CEO) and Asaf Elssibony (VP Innovation), and is based in Israel.“This investment further solidifies Stanley’s partnership with Humavox to bring wireless charging capabilities to both commercial and industrial applications,” said Larry Harper, VP, Stanley Ventures, the corporate venture arm of Stanley Black & Decker.
Three Steps Technology
Through the transmission of radio frequency over a broad band of frequency waves and converting it into DC energy, Humavox’ ETERNA enables the wireless charging of the battery within the device. NEST, the ETERNA power transmitter (Tx), is the physical charging station. It generates the RF energy received by the Thunderlink, and controls the whole charging process.
Thunderlink, the ETERNA power receiver (Rx), is an element within the device under charge (DUC) and responsible for receiving the RF energy that will ultimately lead to the charging of the battery. Thunderlink combines electronic circuitry and a proprietary RF pickup element. It enables efficient reception of the RF signal resonated by the NEST transmitter, and its conversion back to DC voltage.
The entire process is controlled by Real-Time Charging Optimizer algorithm to assure the power transfer efficiency. The Charging Optimizer manages the energy transmission when one or many devices inside the NEST are power-pending.It also directs the energy outflow to the pickup element within the device, while preventing the waste of energy and stops the energy outflow as soon as the charging process is completed.
