Description

technical field [0001] The invention relates to an online energy management test platform and method, in particular to an energy management algorithm verification platform and method for the fuel cell and storage battery hybrid power of an unmanned aerial vehicle, belonging to the technical field of energy management and control of unmanned aerial vehicles. Background technique [0002] New energy UAV is a new type of electric UAV with the potential of long-duration or even ultra-long-duration. It generally refers to the form of an energy system that uses fuel cells, solar cells, batteries and a variety of power sources mixed with each other. In view of the low energy density of batteries, generally pure battery UAVs have short flight time, and due to the soft discharge characteristics of fuel cells, pure fuel cells are not conducive to large-scale maneuvering flight and have poor anti-gust interference ability, while pure solar cells are unmanned. The aircraft is greatly af...
