Abstract: A mobile charging device may be used to move a battery or a power cord to a target device. The target device may be a vehicle or other equipment with a battery. Power from the power cord or battery in the charging device may be used to provide power to the target device to recharge the battery in the target device. The charging device may couple a power cord to the target device, may couple a connector in the charging device to the target device, or may use a wireless power transfer element such as a coil antenna to transfer power wirelessly to the target device. Sensors may be used to facilitate alignment between the charging device and target device. Sensors may also be used to dynamically detect and avoid foreign objects in the path of the charging device.

Abstract: Wireless power may be transferred using wireless power elements such as coil antennas for inductive wireless power transfer technology or patch antennas for capacitive wireless power transfer technology. These antennas in source equipment may couple in a near-field region to antennas implemented in target equipment. Wireless power may also be transferred from the source equipment to the target equipment using radiating antennas in their far-field regions. Wireless power transfer may be optimized by performing channel estimation operations. Foreign objects can be detected and located using sensors or by analyzing the quality of wireless channels. Optimum power transfer settings may be used to maximize wireless power transfer to a set of the antennas in the target equipment while minimizing power transfer to the foreign object.
