Embodiment approach 1

[0038]

[0039] figure 1 It is a block diagram showing an example of the configuration of charging system 10 in Embodiment 1 of the present invention.

[0040] The charging system 10 has a power supply device 100 , a vehicle 150 , a storage battery 154 , and a charging device 170 .

[0041] The power supply device 100 is installed on the ground or buried so that the power supply unit 103 is exposed from the ground surface g. The power supply device 100 is installed, for example, in a parking lot, and is opposed to the power receiving unit 153 to supply power to the charging device 170 while the vehicle 150 is parked. In addition, the configuration of the power supply device 100 will be described later.

[0042] Vehicle 150 has battery 154 and charging device 170 , and runs with battery 154 as a power source. The vehicle 150 is, for example, HEV (Hybrid Electric Vehicle, hybrid electric vehicle), PHEV (Plug-in Hybrid Electric Vehicle, plug-in hybrid electric vehicle) or EV...

Abstract

Provided is a power supply device capable of appropriately performing power supply processing of a power transmission coil even if a foreign object is heated during power supply. The power feeding device (100) includes: a power feeding coil (103a) facing a power receiving unit (153) provided in a vehicle and feeding power to the power receiving unit (153); and a case (103b) accommodating the feeding coil (103a). In the casing (103b), a first cover (202) is formed on the surface of the casing (103b) opposite to the power receiving unit (153), between the first cover (202) and the power supply coil (103a) and The first cover (202) is opposite to the second cover (203).

Description

technical field [0001] The present invention relates to a power supply device that supplies power to a power receiving unit provided in a vehicle in a contactless manner using electromagnetic induction or magnetic resonance. Background technique [0002] Conventionally, as a non-contact power feeding device, a device installed on the ground to feed power to a power receiving unit mounted on a vehicle is 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 has an annular power transmission coil and a case for accommodating the coil, and is installed on the road surface side of a parking space where the vehicle stops. The power receiving unit has an annular power receiving coil and a case for accommodating the coil, and is installed on the bottom surface of the vehicle at a position opposite to the power transmitting unit installed on the ground. The ...
