Abstract

There is provided a charging system including at least one battery device that includes a secondary cell therein, a charging device that performs contactless power transmission to transmit power to the battery device, and a charging control device that controls the contactless power transmission between the charging device and the battery device, wherein the battery device is a hexagonal cylinder having a bottom surface with a substantially regular hexagonal shape and having a predetermined height, wherein the charging device is a hexagonal cylinder having a bottom surface with a substantially regular hexagonal shape and having a predetermined height, and wherein the contactless power transmission is performed between the charging device and the battery device under control of the charging control device by stacking the battery device on the charging device.

Claims

1. A charging system comprising:

at least one battery device that includes a secondary cell therein;

a charging device that performs contactless power transmission to transmit power to the battery device; and

a charging control device that controls the contactless power transmission between the charging device and the battery device,

wherein the battery device is a hexagonal cylinder having a bottom surface with a substantially regular hexagonal shape and having a predetermined height,

wherein the charging device is a hexagonal cylinder having a bottom surface with a substantially regular hexagonal shape and having a predetermined height, and

wherein the contactless power transmission is performed between the charging device and the battery device under control of the charging control device by stacking the battery device on the charging device.

2. The charging system according to claim 1,

wherein the battery device includes a hole penetrating through a middle portion of a plane and a guide portion formed around the hole and stacked on the charging device at a matching position, and

wherein the charging device includes a hole penetrating through a middle portion of a plane and a convex portion formed around the hole at a position corresponding to the guide portion to protrude from an upper surface.

3. The charging system according to claim 2, wherein the guide portion oscillates by a predetermined amount in a direction in which the hole penetrates, and protrudes from the plane of the battery device, when the battery device is stacked on the charging device.

4. The charging system according to claim 2, wherein an upper portion of the charging control device has a same size as the guide portion formed in the battery device and a lower portion of the charging control device has a size insertable into the hole.

5. The charging system according to claim 1, wherein bottom surfaces of the battery device and the charging device have same sizes and substantially regular hexagonal shapes.

6. The charging system according to claim 1, wherein a handle is formed on at least one side surface of the battery device.

7. The charging system according to claim 1, further comprising:

a charging tray that has a bottom surface with a same shape as the battery device; and

a miniature battery device that is charged by being installed in the charging tray and is a hexagonal cylinder having a bottom surface with a substantially regular hexagonal shape and having a predetermined height.

8. A charging system comprising:

a battery device that includes a secondary cell therein;

a charging device that performs contactless power transmission to transmit power to the battery device; and
