Energy management system of solar unmanned aerial vehicle

Abstract

The invention discloses an energy management system of a solar unmanned aerial vehicle. The system comprises a solar battery assembly, a DC-DC converter, a lithium battery assembly, a lithium battery protection circuit, an energy management control module, an unmanned aerial vehicle master control module and an unmanned aerial vehicle power supply unit. The energy management control module comprises a maximum power tracing module, a battery state detection module, an intelligent charging and discharging module and an energy management controller; the solar battery assembly converts solar energy into electrical energy, the lithium battery assembly serves as the energy storage component of the unmanned aerial vehicle, the energy management control module can monitor the operating states of the solar battery and the lithium battery in real time, controls the energy distribution of the unmanned aerial vehicle, and chooses the appropriate power supply mode according to different situations. The energy management system of the solar unmanned aerial vehicle combines the advantages of the solar battery and the lithium battery, reasonably controls and distributes energy sources for use, improves the use ratio of the solar battery and the lithium battery, effectively overcomes the defect of insufficient energy storage of the existing unmanned aerial vehicle, and increases the endurance of the unmanned aerial vehicle.

Description

technical field [0001] The invention patent designs an energy management system for a solar unmanned aerial vehicle, which belongs to the field of energy management and control of aviation aircraft. Background technique [0002] With the development of UAV technology, UAVs have been vigorously developed in military, industrial, agricultural, transportation, security and other fields. But at present, drones basically use lithium batteries, batteries, fuel cells, etc. as fuel. Limited by the design size of the UAV, the energy carried by the UAV is limited, which limits the time and range of the UAV, and affects the limited load and mission requirements of the UAV. As a brand-new energy source, solar energy has attracted more and more attention due to its clean and non-polluting, inexhaustible source, and simple maintenance measures, which has also prompted the generation and development of solar-powered drones. As the development direction of future drones, solar drones will...
