Problems solved by technology

At this time, if the heat is discharged from the inside of the container to the outside, the temperature around the electrode terminal is likely to rise.
If the temperature around the electrode terminal rises, the current that can flow into the electrode terminal is limited, and the deterioration of the electrode terminal is likely to be promoted

[0040] (Outline of battery housing structure)

[0041] The first embodiment relates to a battery housing structure of a power storage device. The battery housing structure of the first embodiment is preferably combined with components such as a bidirectional converter, a transformer, and a control circuit to form a power storage device. The power storage device is preferably connected to the power system for regulating the supply and demand of power. The battery housing structure of the first embodiment may be combined with other components to form devices other than the power storage device.

[0042] figure 1 and figure 2 is a schematic diagram of the battery housing structure of the first embodiment. figure 1 is a stereogram, figure 2 is a sectional view.

[0043] In the battery containing structure 1000 of the first embodiment, as figure 1 and figure 2 As shown, modular batteries 1002 are housed in modular battery holders 1004 . The module battery 1002 may also ...

Abstract

A module battery is accommodated in a housing shelf of a module battery. In the module battery, an electric cell is accommodated within a container. The electric cell is a sodium-sulfur battery. The container is provided with a high-thermal-conductivity wall in which the thermal conductivity is relatively high, as well as a low-thermal-conductivity wall in which the thermal conductivity is relatively low. The first part of a plate overlaps the outer surface of the high-thermal-conductivity wall, and the second part of the plate protrudes from the outer surface of the high-thermal-conductivity wall. The second part surrounds the first part. The first major surface of the plate is directly contacted in the first part with the outer surface of the high-thermal-conductivity wall and is away from the container in the second part. The second major surface of the plate is exposed to the space to which heat is released. An opening may or may not be formed in the first part. A heat-transfer medium may be sandwiched between the first wall and the first part.

Description

technical field [0001] The invention relates to a battery containing structure of an electric power storage device. Background technique [0002] Sodium-sulfur batteries need to work at high temperatures. Therefore, as disclosed in Patent Document 1, a sodium-sulfur battery is used in a state where the cells are housed in a container (heat-insulating container) together with a heater and the like. However, as described in paragraph 0010 of Patent Document 1, since the temperature inside the container is not expected to rise excessively, heat is discharged from the inside of the container to the outside as necessary. [0003] On the other hand, as shown in Patent Document 2, a battery (module battery) in which the unit cells of a sodium-sulfur battery is housed in a container can also be used in a state of being housed in a battery container (pouch). At this time, if the heat is discharged from the inside of the container to the outside, the temperature around the electrode...
