WIRELESS CHARGING SYSTEM FOR VEHICLE
First Claim
1. A wireless charging system for a vehicle which transmits electric power outputted from a feeding apparatus to a vehicle side in a non-contact manner to thereby charge a battery mounted on the vehicle, wherein the feeding apparatus includes:
- an electric power output section which outputs AC power;
a modulation section which superimposes a control signal on the AC power outputted from the electric power output section by using a predetermined modulation method;
an electric power amplifying section which amplifies the AC power modulated by the modulation section; and
a first communication terminal which transmits the AC power amplified by the electric power amplifying section, andwherein the vehicle includes;
a second communication terminal which receives the AC power transmitted from the first communication terminal;
a demodulation section which demodulates the AC power received by the second communication terminal to thereby extract the control signal; and
a rectifying section which rectifies the AC power and supplies a DC power obtained by rectifying the AC power to the battery.

Abstract
A control signal is superimposed on an AC power at the time of charging the battery of an electric car in a non-contact manner by electric power outputted from a feeding apparatus. A feeding apparatus 11 includes a carrier oscillator 21 for outputting an AC power, an ASK modulator 22 for superimposing a control signal on the AC power outputted from the carrier oscillator 21 according to the ASK modulation method, a power amplifier 23 for amplifying the AC power modulated by the ASK modulator 22, and a first resonance coil 24 for outputting the AC power amplified by the power amplifier 23. A charging apparatus 12 to be provided on an electric car includes a second resonance coil 31 for receiving the AC power transmitted from the first resonance coil 24, an ASK demodulator 34 for demodulating the received AC power to thereby extract the control signal, and a rectifier 33 which rectifiers the received AC power to obtain a DC power and supplies the DC power to a battery 35.
