Abstract

A battery holding device is configured to hold a capacitor including at least one storage cell and includes a cell holder and a heater wire. The cell holder is provided at a side surface of at least one storage cell and has a concave-convex surface facing the at least one storage cell. The concave-convex surface has a protrusion contacting the at least one storage cell. At least a portion of the heater wire is embedded in the cell holder.

Claims

1. A battery holding device configured to hold a capacitor including at least one storage cell, the battery holding device comprising:

a cell holder provided at a side surface of at least one storage cell and having a concave-convex surface facing the at least one storage cell, the concave-convex surface having a protrusion contacting the at least one storage cell; and

a heater wire at least a portion of which is embedded in the cell holder.

2. The battery holding device according to claim 1, wherein the at least a portion of the heater wire embedded in the cell holder extends along the protrusion.

3. The battery holding device according to claim 1,

wherein the concave-convex surface includes linear protrusions and linear recessed portions, the linear protrusions and the linear recessed portions are alternately provided on the concave-convex surface, and

wherein the at least a portion of the heater wire embedded in the cell holder extends along at least two of the linear protrusions adjacent to each other.

4. The battery holding device according to claim 1,

wherein the at least one storage cell and a recessed portion of the concave-convex surface form a ventilation path to introduce cooling air from outside of the battery holding device.

5. The battery holding device according to claim 4, wherein the ventilation path and the heater wire extending along the protrusion and embedded in the cell holder extend in substantially a same direction.

6. The battery holding device according to claim 3, wherein the at least a portion of the heater wire embedded in the cell holder is bent at ends of the linear protrusions adjacent to each other so that the at least a portion of the heater wire extends along the adjacent linear protrusions.

7. The battery holding device according to claim 6, wherein a thickness of the linear recessed portions is greater than a diameter of the at least a portion of the heater wire.

8. The battery holding device according to claim 1, wherein the cell holder is formed of an insulating material.

9. The battery holding device according to claim 1, wherein the at least one storage cell and the cell holder are integrally formed with each other.

10. The battery holding device according to claim 1, wherein the capacitor includes a first storage cell and a second storage cell, and wherein the cell holder is provided between the first storage cell and the second storage cell.

11. A battery holding device configured to hold a capacitor including at least one storage cell, the battery holding device comprising:

cell holding means for holding the at least one storage cell, the cell holding means having a concave-convex surface facing the at least one storage cell, the concave-convex surface having a protrusion contacting the at least one storage cell; and

heating means for heating the cell holding means, at least a portion of the heating means being embedded in the cell holding means.

12. The battery holding device according to claim 11, wherein the capacitor includes a first storage cell and a second storage cell, and wherein the cell holding means is provided between the first storage cell and the second storage cell.
