Abstract

An energy storage apparatus includes: an energy storage device unit having at least one energy storage device; an electric device electrically connected to the energy storage device unit, an electric wire, and a restriction part. The electric wire is connected to the electric device via a connector. The restriction part restricts a posture of a protruding portion, which is a portion of the electric wire protruding from the connector, to a posture inclined downward from the connector.

First claim

The invention claimed is:

1. An energy storage apparatus comprising:
an energy storage device unit including at least one energy storage device;
an electric device electrically connected to the energy storage device unit;
an electric wire connected to the electric device via a connector; and
a restriction part that restricts a posture of a protruding portion of the electric wire, the protruding portion being a portion protruding from the connector, to a posture inclined downward from the connector and the restricting part is arranged below the connector.

2. The energy storage apparatus according to claim 1 , wherein a plurality of the electric wires are connected to the electric device via the connector, and the restriction part collectively restricts a posture of the protruding portion of each of the plurality of electric wires to a posture inclined downward.

3. The energy storage apparatus according to claim 1 , wherein a water reception part made of a non-metal is disposed below an end of the protruding portion of the electric wire on a side opposite to the connector.

4. The energy storage apparatus according to claim 1 , further comprising
a cover member that covers the electric device and the electric wire from above,
wherein the restriction part is disposed on the cover member and presses the protruding portion of the electric wire from above to restrict the posture of the protruding portion to a posture inclined downward.

5. The energy storage apparatus according to claim 1 , further comprising:
a plate-shaped member disposed to partition the electric device and the energy storage device unit from each other; and
an opening cover covering an opening that is formed in the plate-shaped member and that exposes a part of the energy storage device unit,
wherein the restriction part is disposed on a surface of the opening cover on a side of the electric device.

6. The energy storage apparatus according to claim 1 , wherein
the energy storage apparatus includes a plurality of the electric devices, and
the electric wire is disposed to connect two of the plurality of the electric devices.

7. The energy storage apparatus according to claim 1 , wherein the restricting part has a space below the restricting part for passing the electric wire through.

8. The energy storage apparatus according to claim 1 , wherein the restricting part has an engagement part for engaging the electric wire.

9. The energy storage apparatus according to claim 1 , wherein the restricting part restricts a middle position of the electric wire to the downward direction.

10. The energy storage apparatus according to claim 1 , wherein the restricting part hooks a portion of the electric wire inclined to the downward direction from the connector.

11. The energy storage apparatus according to claim 1 , wherein the restricting part restricts a predetermined position of the electric wire to incline in the downward direction.

12. The energy storage apparatus according to claim 1 , further comprising a water reception part disposed adjacent to the restricting part.

13. An energy storage apparatus comprising:
an energy storage device unit including at least one energy storage device;
an electric device electrically connected to the energy storage device unit;
an electric wire connected to the electric device via a connector; and
a restriction part that restricts a posture of a protruding portion of the electric wire, the protruding portion being a portion protruding from the connector, to a posture inclined downward from the connector,
wherein the restricting part has a space below the restricting part for passing the electric wire through.

14. The energy storage apparatus according to claim 13 , wherein the restricting part has an engagement part for engaging the electric wire.

15. The energy storage apparatus according to claim 13 , wherein the restricting part restricts a middle position of the electric wire to the downward direction.

16. The energy storage apparatus according to claim 13 , wherein the restricting part hooks a portion of the electric wire inclined to the downward direction from the connector.

17. The energy storage apparatus according to claim 13 , wherein the restriction part presses the protruding portion of the electric wire from above to restrict the posture of the protruding portion to a posture inclined downward.

18. An energy storage apparatus comprising:
an energy storage device unit including at least one energy storage device;
an electric device electrically connected to the energy storage device unit;
an electric wire connected to the electric device via a connector; and
a restriction part that restricts a posture of a protruding portion of the electric wire, the protruding portion being a portion protruding from the connector, to a posture inclined downward from the connector,
wherein the restricting part is configured with an engagement part for engaging the electric wire.

19. The energy storage apparatus according to claim 18 , wherein the restricting part restricts a middle position of the electric wire to the downward direction.

20. The energy storage apparatus according to claim 18 , wherein the engaging part hooks a portion of the electric wire inclined to the downward direction from the connector.
