Abstract
Disclosed are a multi pickup coil for wireless charging of an electric vehicle such as an electric bus or an electric passenger car and industrial equipment while stopping or driving, and a pickup apparatus having the multi pickup coil. The multi pickup coil and the pickup apparatus provide high-capacity and high-efficiency wireless charging per unit area by performing performance enhancement through an optimal design in order to overcome the limitations of a circular pickup coil.
Claims11
A pickup apparatus for wireless charging of an electric vehicle and an industrial equipment, comprising:
- a multi pickup coil disposed distally from the vehicle and including a central coil disposed in the center portion, wing coils disposed on both sides of the central coil, and an outer coil disposed outside of the central coil and the wing coils;
- a ferrite core disposed adjacent to the multi pickup coil;
- a heat dissipation plate for receiving and discharging heat generated from the ferrite core;
- and
- a heat dissipation member disposed between the ferrite core and the heat dissipation plate, electrically insulating the ferrite core and the heat dissipation plate, and made of a material having high thermal conductivity,
- wherein turn numbers of the central coil and the outer coil of the multi pickup coil are determined to reduce a degree of saturation of the ferrite core while maintaining a required voltage, and leakage magnetic fields of multi pickup coil cables exposed to an outside are attenuated.
