VEHICLE POWER SUPPLY APPARATUS AND VEHICLE WINDOW MEMBER
First Claim
1. A vehicle power supply apparatus supplying electric power by electromagnetic induction from outside a vehicle to a predetermined power-supplied object mounted in the vehicle, the vehicle power supply apparatus comprising:
- a power transmitting unit including a power transmission side coil for generating an alternating magnetic field, a positioning device for positioning the power transmission side coil with respect to the vehicle, and a power transmission side circuit supplying electric current to the power transmission side coil; and
a power receiving unit including a power receipt side coil disposed in a non-magnetic portion of the vehicle and generating induced current based on the alternating magnetic field generated by the power transmission side coil, and a power receipt side circuit supplying electric power based on the induced current generated by the power receipt side coil to the power-supplied object.
