Abstract

A reefer container includes: a box-shaped container body; a load equipped in the container body; and a power receiving portion which is configured to receive power from an outside and to supply the power to the load. The power receiving portion includes a power receiving coil which is configured to contactlessly receive the power from the outside.

First claim

The invention claimed is:

1. A reefer container comprising:
a rectangular cuboid container body being formed from a plurality of plates including a first plate and a second plate;
a load equipped in the container body;
a power receiving portion which is configured to receive power from an outside and to supply the power to the load, the power receiving portion being provided on the first plate; and
a power supply portion being provided at a position that opposes the power receiving portion and connected to the power receiving portion via the load, the power supply portion being provided on the second plate, wherein
the power receiving portion comprises a power receiving coil which is configured to contactlessly receive the power from the outside,
the first plate is positioned to face the second plate,
the plurality of plates comprises a rectangular bottom plate, side plates which stand on the bottom plate an surround four sides of the bottom plate, and a top plate which blocks an upper end opening formed by the side plates,
the first plate is one of the side plates, and
the power supply portion is configured to supply power received by the container body to the power receiving portion of another adjacent container body when a plurality of the container bodies are arranged to be horizontally adjacent.

2. The reefer container according to claim 1 , wherein
the power receiving portion is provided in both the first plate and a third plate,
the power supply portion is provided in both the second plate and a fourth plate,
the third plate is positioned to face the fourth plate, and
the third plate is the bottom plate.

3. The reefer container according to claim 2 , wherein
the second plate is one of the side plates and the fourth plate is the top plate.

4. The reefer container according to claim 1 ,
further comprising: a power receiving connection portion to which a power cable which is configured to supply the power from the outside is connected.

5. A power supply system for a reefer container comprising:
the reefer container according to claim 1 ; and
a main power supply apparatus which is configured to contactlessly supply power to the reefer container.

6. The power supply system according to claim 5 , wherein
a power supply coil of the power supply portion is sheet-shaped.

7. A reefer container comprising:
a rectangular cuboid container body being formed from a plurality of plates including a first plate and a second plate;
a load equipped in the container body;
a power receiving portion which is configured to receive power from an outside and to supply the power to the load, the power receiving portion being provided on the first plate; and
a power supply portion being provided at a position that opposes the power receiving portion and connected to the power receiving portion via the load, the power supply portion being provided on the second plate, wherein
the power receiving portion comprises a power receiving coil which is configured to contactlessly receive the power from the outside,
the first plate is positioned to face the second plate,
the plurality of plates comprises a rectangular bottom plate, side plates which stand on the bottom plate and surround four sides of the bottom plate, and a top plate which is disposed at an upper end opening formed by the side plates,
the first plate is the bottom plate, and
the power supply portion is configured to supply power received by the container body to the power receiving portion of another container body stacked on the container body when a plurality of the container bodies are vertically stacked.

8. The reefer container according to claim 7 , wherein
the power receiving portion is provided in both the first plate and a third plate,
the power supply portion is provided in both the second plate and a fourth plate,
the third plate is positioned to face the fourth plate, and
the third plate is one of side plates.

9. The reefer container according to claim 8 , wherein
the second plate is the top plate and the fourth plate is one of the side plates.

10. The reefer container according to claim 7 ,
further comprising: a power receiving connection portion to which a power cable which is configured to supply the power from the outside is connected.

11. The reefer container according to claim 7 , wherein
a power supply system of the power receiving portion is an electromagnetic induction system.

12. The reefer container according to claim 7 , wherein
a power supply system of the power receiving portion is a magnetic field resonance system.

13. A power supply system for a reefer container comprising:
the reefer container according to claim 7 ; and
a main power supply apparatus which is configured to contactlessly supply power to the reefer container.

14. The power supply system according to claim 13 , wherein
a power supply coil of the power supply portion is sheet-shaped.
