Abstract
A wireless power distribution system and method for power tools and other battery-powered devices. The system includes a power transmitter and a plurality of power harvesters or receivers. The receivers are located in power tools, battery packs that are attachable to and detachable from the power tools, a device or case that is interfaceable with the power tool or battery pack, conventionally-sized batteries, or other battery-powered devices. The power transmitter transmits radio frequency (“RF”) power signals to the receivers that are within transmission range of the power transmitter. The receivers receive the RF power signals and convert the RF power signals into direct current. The direct current is used to charge a battery, directly power a tool, etc.
