The Study of Electrical Energy Power Supply
The article aims to research power supply, energy consumption on UAVs, and a method of taking advantage of external
Compared to the present EMS, the suggested EMS leaves around 23.5% energy in the batteries after a single day-night cycle. These types of UAVs strongly depend on solar power. Multiple batteries or a hybrid power supply system with a battery, supercapacitor and fuel cell can serve as power sources.
Comprehensive state of the art review on electric unmanned aerial vehicles. UAVs critical evaluation of power supply structures and energy management systems. UAVs development gaps, useful guiding recommendations, and prospects. The interest in electric unmanned aerial vehicles (UAVs) is rapidly growing in recent years.
Power can also be supplied using a passive method, which is widely used for small UAVs as in, . In this case, the power sources are directly connected to a DC link and supply the propulsion according to their own characteristics.
It is worth noting that most available electrical UAVs are using a fuel cell as the main power source. A supercapacitor can also contribute to the power supplying process since it has very high power density and quick response to peak power needed in UAV takeoff and sudden maneuvers.
