Description

technical field [0001] The present invention relates to a power supply system for unmanned aerial vehicles, in particular to a group unmanned aerial vehicle power supply device based on electromagnetic coupling non-contact charging, which is used to charge multiple small unmanned aerial vehicles at the same time to ensure the battery life of unmanned aerial vehicles . Background technique [0002] Compared with manned aircraft, UAVs have many advantages: small and light, not easy to be found, low development and maintenance costs, good maneuverability, and low take-off and landing requirements. With the popularization of drones, its application fields have covered scientific research, civilian and military. There are more than 30 countries engaged in the research and production of UAVs in the world, and the number of basic types of UAVs has increased to more than 300. [0003] Among the various indicators for evaluating the performance of drones, the endurance of drones is...

Problems solved by technology

For the former, since the relatively mature battery technology has developed to the bottleneck period, a larger battery capacity means a larger battery volume and weight, so increasing the battery capacity will definitely affect the maneuverability and lightweight of the UAV; For the method of power supply through multiple times, if it is based on the charging technology of the traditional contact power conduction method, it means that the UAV needs to return to the base station or home port when it needs to replenish power, and invest in manpower. Its charging, obviously, this method is insufficient in terms of reliability, flexibility, convenience, etc., and the hovering charging form based on this method is low in safety, and has high requirements on the technical performance of the drone , it is difficult to realize
