POWER SUPPLY UNIT, POWER RECEIVING UNIT, AND POWER SUPPLY SYSTEM

摘要

Provided is a power supply system in which an electromagnetic leakage is prevented. A power supply side resonance coil provided to a power supply unit and a power receiving side resonance coil provided to a power receiving unit are housed respectively in a conductive power supply side shield case and power receiving side shield case. The power supply side shield case is formed of a bottom wall covering a side of the power supply side resonance coil spaced apart from the power receiving side resonance coil and a vertical wall erecting from a periphery of the bottom wall, and a ferrite is provided onto surfaces of the bottom wall and the vertical wall.

主权项

1. A power supply unit comprising:
a power source; a power supply side resonance coil configured to resonance with a power receiving side resonance coil mounted to a vehicle to supply power supplied from the power source to the power receiving side resonance coil in a non-contact manner; and a conductive shield case formed of a bottom wall covering a side of the power supply side resonance coil spaced apart from the power receiving side resonance coil and a vertical wall erecting from a periphery of the bottom wall, and housing the power supply side resonance coil, wherein a magnetic body is provided onto a surface of the vertical wall of the shield case, and the magnetic body is provided onto an outer surface of the shield case.
