Efficient mid-range power transfer to multiple devices

Agiltron proposes a new type of portable inductively coupling wireless battery charger station to relieve the logistic footprint and operation complexity of the wired power connection for charging battery-operated devices in the battlefield management. The wireless battery charger station will allow power transfers greater than 5 meters from the charging source with efficiency more than 50%. The power transmitter subsystem will weigh less than 10 kg with the maximum diameter of 0.15m. The portable receiver/battery charger subunit will weigh less than 6 kg. Power can transfer through many common materials like tent canvas and plywood. The system is low cost, robust and easy to maintenance. In Phase II, the design, fabrication, and power transfer and evaluation testing will be performed for prototypes of the wireless battery charger. Higher-volume production is expected in Phase III for delivery to the Army and other customers.
