Non-contact power supply system and power transmission apparatus, and designing method and installing method of power transmission apparatus
First Claim
1. A non-contact power supply system, comprising:
- a power receiving unit which is mounted between two front wheels of a vehicle;
a power transmitting unit which is disposed on a plane and which transmits electric power to the power receiving unit in a non-contact manner; and
a housing which projects in a vertical direction from the plane and which accommodates the power transmitting unit,wherein the housing has a height in a vertical direction which satisfies a condition that a vertical height of a first gap in a front of the housing is less than 15 cm and equal to or more than 5 cm in a position where the power transmitting unit and the housing face the power receiving unit mounted between the two front wheels, the first gap being defined by a bottom surface of the vehicle and an upper surface of the housing, andwherein a second gap in a rear of the housing, which is defined by the bottom surface of the vehicle and the upper surface of the housing, is larger than the first gap.

Abstract
A non-contact power supply system includes a power receiving unit mounted on a vehicle, a power transmitting unit which is disposed on a plane and which transmits electric power to the power receiving unit in a non-contact manner, and a housing which projects in a vertical direction from the plane and which accommodates the power transmitting unit. The housing has a height in a vertical direction which satisfies a condition that a vertical height of at least part of a gap defined by a bottom surface of the vehicle and an upper surface of the housing is less than 15 cm and equal to or more than 5 cm. Therefore, the non-contact power supply system which satisfies a standard for exposure of a human body to electromagnetic field and which is free from an occurrence of a physical contact with a bottom surface of a vehicle is provided.
