Embodiment Construction

[0020] One aspect of the present disclosure is a first coil device that faces a second coil device in a facing direction and is used for non-contact power transmission or reception. The first coil device includes a first coil unit and a first auxiliary coil unit. The magnetic member, the first auxiliary magnetic member is provided adjacent to the first coil portion in a first direction perpendicular to the facing direction, and the first auxiliary magnetic member is configured to be further away from the first coil portion in the first direction. while approaching the second coil arrangement.

[0021] The first coil device is opposite to the second coil device, and conducts power transmission or power supply in a non-contact manner. A first auxiliary magnetic member is provided adjacent to the first coil portion. When a displacement occurs between the pair of coil devices in the first direction, the first coil part does not face the second coil part of the second coil device....

Abstract

The present invention provides a coil device, a non-contact power supply system, and an auxiliary magnetic component. The first coil device and the second coil device are opposed in the opposing direction, and are used for non-contact power transmission or reception, and include: a first coil part, and a first A first auxiliary magnetic member provided adjacent to the coil portion. The first auxiliary magnetic member is configured to approach the second coil device as it moves away from the first coil portion in the first direction.

Description

technical field [0001] The present disclosure relates to a coil device, a contactless power supply system, and an auxiliary magnetic component. This application claims the priority of Japanese Patent Application No. 2014-226738 for which it applied on November 7, 2014, and uses the whole content in this application by reference. Background technique [0002] The non-contact power supply system has a power transmission coil device and a power reception coil device, and realizes non-contact power transmission by utilizing electromagnetic induction and magnetic field resonance between the coils. Examples of applications of the non-contact power supply system include power supply systems for electric vehicles and plug-in hybrid vehicles. In this case, the power receiving coil device is mounted on the vehicle. [0003] On the other hand, the power transmission coil device is installed in a parking space or the like. For example, as described in Patent Document 1, the power tra...
