Power receiving device and power transmitting device
First Claim
1. A power receiving device comprising:
- a power receiving unit that receives electric power from an external power transmitting unit contactlessly; and
a casing having said power receiving unit accommodated therein, said casing includinga lid member located on said power transmitting unit'"'"'s side and allowing a magnetic field to pass therethrough, anda plurality of temperature sensors provided at said lid member and sensing in temperature a foreign matter present between said power transmitting unit and said power receiving unit, said temperature sensors being spaced closer together at a location of a strong portion of an electromagnetic field strength generated from said power receiving unit than a location of a weak portion of said electromagnetic field strength generated from said power receiving unit.
