Self-charging unmanned aerial vehicle

A method of operating an unmanned aerial vehicle (UAV), comprising:

• powering, by a first battery of the UAV, a first plurality of electronic components of the UAV, a power consumption of each of the first plurality of electronic components being greater than a power threshold;
• powering, by a second battery of the UAV, a second plurality of electronic components of the UAV, a power consumption of each of the second plurality of electronic components being less than or equal to the power threshold;
• generating, by a generator of the UAV, an electrical power through rotation of a shaft of a motor of the UAV;
• charging, by a battery management system (BMS) of the UAV, the first battery using the electrical power generated by the generator when the UAV is during operation and a stored charge of the first battery drops to a first predefined level;
• and
• charging, by the BMS of the UAV, the second battery using the stored charge of the first battery when a stored charge of the second battery drops to a second predefined level.
