Description

technical field [0001] The invention relates to an electric aircraft charging technology, in particular to an electric aircraft wireless charging system and a charging alignment method. Background technique [0002] With the vigorous promotion of clean energy, countries are vigorously developing low-carbon emission vehicles, such as electric vehicles and electric aircraft. In recent years, Europe, America, Japan and China have successively launched various electric aircraft. The capacity is large and the charging time is long. At present, most electric aircraft use manual wired charging or contact charging. [0003] CN104734294A discloses a charging system for an electric rotorcraft. The charging part of the system includes a charging platform and a windproof wall, and the airborne part includes a power receiving device and an onboard battery. Among them, the conductive contact surface with good conductivity is set on the charging platform, and the electric rotorcraft direc...

AI Technical Summary

Problems solved by technology

Among them, the conductive contact surface with good conductivity is set on the charging platform, and the electric rotorcraft directly contacts with the contact surface through the conductor to realize conductive charging; although the existing contact charging can realize automatic charging, there are It is prone to problems such as leakage, poor contact and low protection level, while conventional wired charging requires manual intervention, and the process is cumbersome and cannot be automated
