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...

Examples

Embodiment 2

[0031] Such as Figure 5 As shown, when the battery of the electric aircraft is low, the electric aircraft will automatically drive to the charging position, and the vertical distance between the transmitting reel and the receiving reel is fixed. Due to the large error when the electric aircraft is moving on the ground, it cannot meet the requirements of wireless charging at X Alignment accuracy requirements in the direction and Y direction, so when the electric aircraft reaches the charging position, the laser ranging sensor X1 and laser ranging sensor X2 in the X direction and the laser ranging sensor Y1 and laser ranging sensor in the Y direction through the launch plate The sensor Y2 performs positioning. The positioning principle is that the area of ​​the transmitting coil and the receiving coil is 1:1. Since the receiving coil on the belly of the aircraft is the closest to the transmitting coil, when the receiving coil is offset relative to the transmitting coil in the X ...
