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, gasoline-electric hybrid vehicle), PHEV (Plug-in Hybrid Electric Vehicle, plug-in hybrid electric vehic...

Abstract

A power supply apparatus capable of appropriately supplying electrical power to a power transmission coil even if a foreign object is heated during power supply. The power supply apparatus (100) is provided with a power supply coil (103a) opposing a power-receiving unit (153) provided to a vehicle and supplying power to the power-receiving unit (153), and a housing (103b) accommodating the power supply coil (103a). In the housing (103b), a first cover (202) is formed on a surface of the housing (103b) opposing the power-receiving unit (153), and a second cover (203) opposing the first cover (202) is arranged between the first cover (202) and the power supply coil (103a).

Description

technical field [0001] The present invention relates to a power supply device that uses electromagnetic induction to supply power in a non-contact manner to a power receiving unit provided in a vehicle. Background technique [0002] Conventionally, as a non-contact power feeding device, a device installed on the ground and feeding power to a power receiving unit mounted on a vehicle is known (for example, Patent Document 1). [0003] In Patent Document 1, two units are included: a power transmission unit and a power reception unit. 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 place where the vehicle stops, such as a parking space. 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 cas...
