Today’s warfighter and NETT Warrior are reliant on small battery operated devices for communication, information systems, enemy detection, and battlefield management. These devices must be recharged on a regular basis to ensure sustained operation. Current charging technologies require the device to be plugged into a charging station via a wired connection. This wired power connection requirement decreases the battlefield flexibility due to limited number of units that can be charged at one time. The Nett Warrior uses a battery to power various Soldier-worn components. Space limitations and the dynamic nature of the battlefield suggests that carrying extra batteries and chargers will adversely impact the Soldier's mobility and readiness while transported by a ground vehicle. Cordless battery charging technology could have a dramatic impact on the portable electronic devices being used on the modern battlefield. This cordless technology could be harnessed in several applications to ease the logistical footprint and increase the flexibility of the devices. The goal should allow the operations served by the wireless battery charging system to stay and go wherever needed. We aim to achieve and implement a design that will support smart and intelligent and highly efficient cordless/wireless battery charging at a range of 2 feet.
