Abstract
The present invention discloses a UAV charging system and method based on laser wireless energy transmission, including: a UAV system, a mission payload, and a laser wireless energy transmission system; wherein the laser wireless energy transmission system further includes a ground vehicle-mounted transmitting system and an airborne receiving system. The present invention uses a high-energy laser beam as an energy carrier, which is emitted through a collimated optical system, and converts light energy into electrical energy at the remote end using a laser battery array, thereby realizing non-contact power supply to remote electrical equipment, and is an effective means of long-distance wireless energy transmission. Using the laser wireless energy transmission method of the present invention to charge a UAV can provide a new energy supply method for the UAV, increase the flight time, and enhance the use value.
