Energous Corporation today announced the results of an industry-first, independent performance evaluation completed by Underwriters Laboratories, Inc. (UL). The UL testing, which was conducted at their labs, evaluated the performance of the award-winning WattUp technology and validated receive power at various distances, simultaneous multiple device receive capability as well as mobility.
"We are pleased to have the leading independent testing facility confirm that WattUp exceeded performance expectations for delivering power within various charging ranges," said Stephen R. Rizzone, CEO of Energous. "As the leader in the emerging Uncoupled Power market, we have set the bar and validated the performance of Energous' award-winning WattUp wireless charging solution. These results independently document the rapid progress of our product development efforts that are expected to enable us to release products to the consumer through our licensing partnerships in late 2016, early 2017."
Targeted performance for the WattUp wireless charging system is: 4W delivered within 0-5 feet; 2W delivered within 5-10 feet; and 1W delivered within 10-15 feet. The UL testing conducted in their lab measured the amount of actual power delivered to a device at varying distances from a single WattUp transmitter. The measures of actual power received by a device were: 0-5 feet, 5.55W was delivered to the receiver; 5-10 feet, 3.74W was delivered to the receiver; and 10-15 feet, 1.06W was delivered to the receiver. UL also tested a single transmitter sending power simultaneously to multiple receivers at a distance of five feet yielding the following results: Receiver 1 received 5.44W and Receiver 2 received 6.66W.
UL testing facilities did not have a robotic arm capable of simulating motion. To validate mobility, a single WattUp transmitter located, acquired and transmitted power sequentially in near-real-time to four WattUp receivers spread 30 degrees apart, equidistant at 8.5 feet. Actual power delivered in sequence is as follows: Receiver 1, 2.36W; Receiver 2, 2.02W; Receiver 3, 2.08W; and Receiver 4, 2.04W.
