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.
本发明涉及油电混动无人机的电池管理技术领域,具体涉及一种用于油电混动无人机的电池管理方法和油电混动无人机。该电池管理方法,在油电混动无人机执行完飞行任务后,进行以下步骤:检测充电电池组中各电池包的当前电压;确定充电电池组中各电池包的当前最低电压;从充电电池组中筛选出当前电压与当前最低电压的第一差值超过第一设定阈值的待放电电池包;对待放电电池包进行放电,用于使待放电电池包的电压与第一差值不超过第一设定阈值。本发明在每次执行完毕飞行任务后,对不均衡的电池包进行放电操作,保证下次该油电混动无人机执行飞行任务时各个电池包之间均是均衡的,提高了油电混动无人机的供电安全性能。
