Abstract
An electrical powered vehicle includes a secondary self-resonant coil, a secondary coil, a rectifier, and a power storage device. The secondary self-resonant coil is configured to be magnetically coupled with a primary self-resonant coil of a power feeding device by magnetic field resonance, and allow reception of high frequency power from the primary self-resonant coil. The secondary coil is configured to allow reception of electric power from the secondary self-resonant coil by electromagnetic induction. The rectifier rectifies the electric power received by the secondary coil. The power storage device stores the electric power rectified by the rectifier.
Claims8
An electrical powered vehicle comprising:
- a secondary self-resonant coil configured to be magnetically coupled with a primary self-resonant coil external to a vehicle by magnetic field resonance, and allow reception of electric power from said primary self-resonant coil,
- a secondary coil configured to allow reception of electric power from said secondary self-resonant coil by electromagnetic induction,
- a rectifier for rectifying electric power received by said secondary coil,
- a power storage device for storing electric power rectified by said rectifier, and
- an electric motor for receiving supply of electric power from said power storage device to generate a driving force of the vehicle,
- an adjustment device configured to allow adjustment of a resonant frequency of said secondary self-resonant coil by modifying at least one of a capacitance and inductance of said secondary self-resonant coil,
- an electric power detection device for detecting electric power received by said secondary self-resonant coil and said secondary coil, and
- a control device for controlling said adjustment device such that electric power detected by said electric power detection device is at a maximum.
