Abstract

The application belongs to the technical field of power supply systems of compound wing unmanned aerial vehicles, and particularly relates to a low-temperature battery heat preservation and power compensation system and method for a compound wing unmanned aerial vehicle, which comprises a flight control computer for controlling the compound wing unmanned aerial vehicle, and further comprises an intelligent battery thermal management module, a pneumatic and power collaborative compensation module and a rotor deicing module which are electrically connected with the flight control computer; in operation, the intelligent battery thermal management module sets a low-temperature compensation triggering condition, and in flight, it is determined whether the low-temperature compensation triggering condition is met; if yes, the intelligent battery thermal management module actively heats the battery of the compound wing unmanned aerial vehicle, and passively stores heat at intervals of the battery, so as to improve the temperature stability and energy saving property of the system. The dynamic power regulation avoids overheating and energy waste, actively avoids the risk of stalling, finds a balanced control interval between battery heat preservation and flight attitude control, and provides a safe basis for low-temperature flight.
