Abstract

A power transmitting apparatus (41) is provided with: a power transmitting unit (28), which transmits power, in a non-contact manner, to a power receiving unit (27) that is provided outside; and a cylindrical power transmitting-side shield (102), which is provided to surround the power transmitting unit (28). On the power transmitting-side shield (102) side, i.e., the reverse side of a region where the power receiving unit (27) is positioned, electromagnetic waves can pass through, and a shield member (103) is provided on the power transmitting-side shield (102) side, i.e., the reverse side of the power transmitting unit (28) with the power transmitting-side shield (102) between the power transmitting-side shield and the shield member.

Description

technical field [0001] The invention relates to a power transmission device, a power receiving device and a power transmission system. Background technique [0002] In recent years, attention has been drawn to hybrid vehicles, electric vehicles, and the like, which drive drive wheels using electric power from batteries or the like due to environmental considerations. [0003] Especially in recent years, in electric vehicles equipped with batteries as described above, wireless charging capable of charging the batteries in a non-contact manner without using a plug or the like has attracted attention. Furthermore, various charging methods have recently been proposed as non-contact charging methods. [0004] As a power transmission system using a non-contact charging method, for example, JP 2010-070048 A (Patent Document 1), JP 2010-252583 A (Patent Document 2), JP 2008 A - Publication No. 294385 (Patent Document 3), Japanese Patent Application Laid-Open No. 2009-004512 (Paten...
