Embodiment approach 1

[0041]

[0042] figure 1 It is a block diagram showing an example of the configuration of the charging system 10 in Embodiment 1 of the present invention.

[0043] The charging system 10 includes a power supply device 100 , a vehicle 150 , a battery 154 , and a charging device 170 .

[0044] The power supply device 100 is installed or buried on the ground so that the power supply unit 103 is exposed from the ground surface g. The power supply device 100 is installed in, for example, a parking space, and when the vehicle 150 is parked, it opposes the power receiving unit 153 and supplies power to the charging device 170 . In addition, the structure of the power supply apparatus 100 is mentioned later.

[0045] Vehicle 150 includes battery 154 and charging device 170 , and travels using battery 154 as a power source. The vehicle 150 is, for example, a HEV (Hybrid Electric Vehicle), a PHEV (Plug-in Hybrid Electric Vehicle), or an EV (Electric Vehicle) that can utilize the el...

Abstract

The power supply device of the present invention can suppress the thickness of the surface of the power supply case, and prevent foreign objects from being heated and becoming high temperature during the power supply process. In the power supply device (100), on the upper surface (202a) of the case (103b) facing the power receiving unit (153), the power supply coil (103a) is projected onto the case in the direction of the power receiving unit (153). When the body (103b) projects the part of the power supply coil (103a), it is formed in the radial direction of the power supply coil (103a) as it approaches the inner edge portion (211) of the power supply coil (103a) from the top (205) and gradually approaches the power supply coil. The first inclined portion (203) of (103a), as well as the part projecting the power supply coil (103a), is formed in the radial direction of the power supply coil (103a), along with approaching the outer circumference of the power supply coil (103a) from the top (205) (212) and gradually approach the second inclined portion (204) of the power supply coil (103a).

Description

technical field [0001] The present invention relates to a power supply device that supplies power to a power receiving unit installed in a vehicle in a non-contact manner. Background technique [0002] Conventionally, as a non-contact power supply device, a device installed on the ground to supply power to a power receiving unit mounted on a vehicle has been known (for example, Patent Document 1). [0003] In Patent Document 1, two units of a power transmission unit and a power reception unit are included. The power transmission unit includes a ring-shaped power transmission coil and a case that accommodates the coil, and is provided on the road surface side of a position where the vehicle is stopped, such as a parking space. The power receiving unit has a ring-shaped power receiving coil and a case that accommodates the coil, and is provided on the vehicle bottom surface at a position opposite to the power transmitting unit provided on the ground. The case surface (herein...
