Abstract

The invention relates to the technical field of battery management of oil-electricity hybrid unmanned aerial vehicles, and concretely relates to a battery management method for an oil-electricity hybrid unmanned aerial vehicle, and the oil-electricity hybrid unmanned aerial vehicle. The battery management method is carried out after the fuel-electric hybrid unmanned aerial vehicle executes a flight task, and comprises the following steps: detecting the current voltage of each battery pack in a rechargeable battery pack; determining the current minimum voltage of each battery pack in the rechargeable battery pack; screening out a to-be-discharged battery pack of which the first difference value between the current voltage and the current minimum voltage exceeds a first preset threshold value from the rechargeable battery pack; and discharging the to-be-discharged battery pack to enable the voltage of the to-be-discharged battery pack and the first difference value not to exceed the first preset threshold value. After the flight task is executed each time, the unbalanced battery packs are discharged to guarantee that all the battery packs are balanced when the oil-electricity hybridunmanned aerial vehicle executes the flight task next time, so the power supply safety performance of the oil-electricity hybrid unmanned aerial vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of battery management of a hybrid unmanned aerial vehicle, in particular to a battery management method for a hybrid unmanned aerial vehicle and a hybrid unmanned aerial vehicle. Background technique [0002] Unmanned aerial vehicle (UAV) is widely used in [0003] Aerial photography, plant protection, express transportation, disaster relief, surveying and mapping, news reporting, power inspection, film and television shooting and many other fields. According to different power supply methods, UAVs can be divided into battery-powered UAVs, fuel-powered UAVs, and hybrid-powered UAVs. Battery-powered UAVs have short battery life and low payload, while fuel-powered UAVs are complex to control and have poor stability, making it difficult to meet the needs of industrial-grade UAVs. UAVs powered by oil-electric hybrid power are highly favored by domestic and foreign UAV manufacturers because of their dual advant...
