Abstract:
1. 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.
