Abstract

An upper rotation body is rotatably attached on a lower travelling body. A storage battery module is loaded onto the upper rotation body. The storage battery module has a plurality of plate-shaped storage battery cells that are stacked in z direction when an xyz rectangular coordinate system is defined. At least one heat transfer plate is arranged between the storage battery cells. Pressing plates, which are arranged at both ends of the stack structure of the storage battery cells, apply a compressive force in the stacking direction to the storage battery cells. A first wall plate and a second wall plate pinch the stacked body in the y-direction and are fixed to the pressing plates. The positions of the heat transfer plates are restricted with respect to the first wall plate and the second wall plate.

Claims

1. A shovel comprising:

a lower traveling body;

an upper rotation body rotatably attached to the lower traveling body; and

a storage battery module loaded onto the upper rotation body,

wherein the storage battery module comprises;

a stacked body having

a plurality of plate-shaped storage battery cells that are stacked in z-direction when an xyz rectangular coordinate system is defined,

at least one heat transfer plate arranged between the storage battery cells, and

pressing plates, which are arranged at both ends of a stack structure of the storage battery cells, and apply a compressive force in a stacking direction to the storage battery cells; and

a first wall plate and a second wall plate that pinch the stacked body in the y-direction and are fixed to the pressing plates, and

wherein the positions of the heat transfer plates are restricted with respect to the first wall plate and the second wall plate.

2. The shovel according to claim 1,

wherein the heat transfer plates are thermally combined with the first wall plate and the second wall plate.

3. The shovel according to claim 1, further comprising:

a refrigerant channel or irregularities for heat radiation for cooling the first wall plate and the second wall plate.

4. The shovel according to claim 1,

wherein the heat transfer plates are anchored to the first wall plate and the second wall plate.

5. The shovel according to claim 1,

wherein an adhesive having thermal conductivity is arranged between the heat transfer plates and the first wall plate and between the heat transfer plates and the second wall plate.

6. The shovel according to claim 1, wherein the stacked body further comprises first tie rods that couple the pair of pressing plates together and apply a compressive force in the stacking direction to the stack structure of the storage battery cells, and

the shovel further comprises a third wall plate and a fourth wall plate that pinch the stacked body in the x-direction and are fixed to the pair of pressing plates, the first wall plate, and the second wall plate.

8. The shovel according to claim 1, further comprising:

recesses formed in inner surfaces of the first wall plate and the second wall plate; and
