Contactless power supply system and vehicle power supply device

Abstract

The present invention is a contactless power supply system intended to eliminate energy loss due to positional misalignment by supplying power contactlessly in a mated orientation. This contactless power supply system is provided with: a power reception device (120) having a power-supplying secondary coil (121); a power supply device (110) having a power-supplying primary coil (111) and a driving circuit (112); a primary coil support member (140) having mating members (142) that mate with mated members (152), the primary coil support member (140) supporting the power-supplying primary coil; a secondary coil support member (150) having the mated members that mate with the mating members, the secondary coil support member (150) supporting the power-supplying secondary coil; and an orientation/position adjustment mechanism (160) for changing orientation between an open orientation, which is where the mated members are released from the mating members, and a mating orientation, which is where the mating members are mated with the mated members.

Description

technical field [0001] The present disclosure relates to a contactless power supply system and a vehicle power supply device that supplies power to a vehicle capable of receiving power supply. This application claims the benefit of priority of Japanese Patent Application No. 2014-074261 filed on March 31, 2014, the entire contents of which are incorporated by reference. Background technique [0002] In recent years, vehicles driven by electricity are used. [0003] Therefore, it is necessary to supply power to the vehicle. [0004] For example, the power supply equipment is used to supply power to a parked vehicle. [0005] The power supply device can supply power to the vehicle through contactless. [0006] For example, a vehicle has a non-contact secondary coil for power feeding at the bottom of the vehicle, and a concept is being studied in which a primary coil for power feeding is provided under the vehicle to supply power to the vehicle. [0007] Figure 16 It is a ...
