The power supply system includes a power receiving port for receiving power of a predetermined frequency output from the external power source 5, a power feeding circuit, and a power receiving circuit. The power feeding method of this power feeding system is a magnetic field resonance method in which power is supplied by matching the resonance frequency of the power feeding circuit and the resonance frequency of the power receiving circuit. That is, this power feeding system uses the power feeding coil and the power receiving coil as a resonator.

The external power source 5 is, for example, a system power source supplied through a commercial distribution line network. The transport device 2 includes a plug 4 and a power cord 41 that are inserted into an outlet that is a supply port of the external power source 5. The plug 4 is an example of a power receiving port that receives power of a predetermined frequency output from the external power source 5. When the plug 4 is connected to the outlet, the switch 51 is turned on and system power is supplied to the power cord 41. The AC power supplied from the external power supply 5 is supplied to the power supply circuit via the plug 4 and the power cord 41.

The transport device 2 is equipped with a power supply circuit. The feeding circuit includes a capacitor 24 and a plurality of feeding coils connected in parallel to the capacitor 24. The feeding circuit constitutes an LC resonance circuit. For example, it includes three feeding coils 21, 22, and 23. The power feeding coil 21 is built in the power feeding unit 211. The power feeding coil 22 is built in the power feeding unit 221 which is a power feeding pad. The power feeding coil 23 is built in the power feeding unit 231 which is a power feeding pad. The power feeding portion is preferably made of a material through which magnetism easily passes. When the switch 51 is turned on, the capacitor 24 of the power feeding circuit and the capacitor 15 of the power receiving circuit are converted so that the phases of the voltage and the current of the output power match in order to efficiently transmit power. These capacitors function as resonance capacitors.

The power supply circuit further includes a converter 27, a secondary battery 26, and an inverter 25. The secondary battery 26 can store the electric power supplied from the external power source 5 in a state where the power supply circuit does not supply power to the power receiving circuit. When the switch 28 is on, the converter 27 converts the AC power supplied from the external power source 5 into DC power and outputs it to the secondary battery 26. The inverter 25 converts the DC power output from the secondary battery 26 into AC power and outputs it to the capacitor 24 in a state where the power from the external power source 5 is not supplied. As described above, when there is no power supply from the external power source 5, the transport device 2 can supply power by using the stored power of the secondary battery 26.

The temperature control transport box 1 is provided with a power receiving circuit. The power receiving circuit includes a capacitor 15, a power receiving coil 14, and a cooling unit 11. The power receiving circuit constitutes an LC resonance circuit. The power receiving coil 14 outputs the electric power received from the power feeding coil to the capacitor 15 in a state where the power receiving unit 141 and the power feeding unit are close to each other. The capacitor 15 functions as a resonance capacitor. The LC resonance circuit formed in the power receiving circuit and the LC resonance circuit formed in the feeding circuit described above are magnetically coupled to each other. As a result, the LC resonance operation is performed at a resonance frequency that is substantially the same as the power output from the capacitor 24.
