Abstract
A system includes a wireless transmission module configured to transmit electrical energy to a wireless receiver module via reverse wireless charging, one or more electronic components other than the wireless transmission module, a battery configured to provide electrical energy to the wireless transmission module and the one or more electronic components, and a battery management module coupled to the battery and the wireless transmission module. The battery management module is configured to determine an amount of power demanded by the wireless transmission module and the one or more electronic components from the battery and dynamically vary power transfer from the wireless transmission module to the wireless receiver module as a function of the amount of power demanded by the one or more electronic components.
