Abstract

A dynamic power distribution system includes a dynamic powering system that provides dynamic power, an external device, and a powered system that is coupled to the external device and engaging the dynamic powering system. The powered system determines a power budget using the dynamic power received from the dynamic powering system. The powered system also determines a powered system component load for a plurality of powered system components, receives a power request from the external device, and retrieves at least one power distribution rule. Using the powered system component load, the power request, and the at least one power distribution rule, and powered system allocates and distributes a first portion the power budget to the external device, and may also allocate and distribute a second portion the power budget to at least one of the plurality of powered system components. The dynamic powering system may be a wireless powering system.
