Analysis of Output Power of Electric Unmanned Aerial Vehicle Hybrid Energy System Based on Temperature

Abstract

The issue of energy and power systems is the main challenge faced by electric unmanned aerial vehicles for long endurance, and hybrid energy systems are the main way to solve the problem of electric unmanned aerial vehicles for long endurance. Under different operating temperatures, hybrid energy systems generate thermal losses and output power changes. This paper proposes an energy control process for hybrid energy systems based on thermal analysis and conducts simulation analysis. When the solar cell subsystem, fuel cell subsystem, and lithium battery subsystem operate at different temperatures, the flight duration of electric drones changes. The results show that under the operating temperature of solar cells at 25℃ and fuel cells at 66℃, electric drones can fly for 24 hours. When the temperature of the solar panel rises to 35℃ and the working temperature of the fuel cell is at 74℃, the hybrid energy system can only provide 18 hours of power due to changes in the working temperature of the electric drone, reducing the flight time by 6 hours.
