Abstract

The disclosure is related to a system and method for autonomously charging a rechargeable power supply of an Unmanned Aerial System (UAS). The system can have battery power translator (BPT). communicatively coupled to the UAS. The BPT can have an energy source operable to deliver power at a native power level different than a designed power level of the UAS. The BPT can also have a voltage/current translator (VCT) operable to receive energy at the native power level from the energy source, and convert the energy at the native power level to converted energy at the designed power level for use by the UAS. The system can also have a remote charging system (RCS) communicatively coupled to the BPT. The RCS can also have a charging pad having a plurality of configurable terminals, and operable to receive the UAS and deliver recharge energy to the UAS.
