POWER STORAGE APPARATUS AND METHOD OF OPERATING POWER STORAGE APPARATUS
First Claim
1. A power storage apparatus comprising:
- a battery that includes a container, an electric cell of a sodium-sulfur battery, and a charging/discharging path inside the battery, said container including an outer wall and a heat transfer wall, an electric cell chamber and an air chamber being formed inside said container, said heat transfer wall dividing said electric cell chamber and said air chamber, and said electric cell and said charging/discharging path inside the battery being housed in said electric cell chamber;
a charging/discharging path outside the battery that is electrically connected to said charging/discharging path inside the battery;
a sealed container that houses said battery and said charging/discharging path outside the battery;
an intake path formation that is formed with an intake path which starts from outside of said sealed container and leads to said air chamber;
an exhaust path formation that is formed with an exhaust path which starts from said air chamber and leads to outside of said sealed container;
a generation mechanism that generates an air flow which sequentially flows through said intake path, said air chamber, and said exhaust path;
a determination unit that determines whether or not cooling of said electric cell chamber is required; and
a generation control unit that controls said generation mechanism such that said air flow is generated in a case where said determination unit determines that the cooling of said electric cell chamber is required, and said air flow is not generated in a case where said determination unit determines that the cooling of said electric cell chamber is not required.

Abstract
A battery chamber is formed inside a sealed container. A module battery and a charging/discharging path outside a battery are housed in the battery chamber. In the module battery, an electric cell chamber and an air chamber are formed inside a heat-insulating container. The electric cell chamber and the air chamber are divided by a heat transfer wall. An electric cell of a sodium-sulfur battery, and a charging/discharging path inside a battery are housed in the electric cell chamber. An intake path starts from outside of the sealed container and leads to the air chamber. An exhaust path starts from the air chamber and leads to the sealed container. The blower generates an air flow that sequentially flows through the intake path, the air chamber and the exhaust path. In a case where the cooling of the electric cell chamber is required, the air flow is generated.

8. A method of operating a power storage apparatus comprising the steps of:
-
(a) preparing a power storage apparatus including a battery, a charging/discharging path outside the battery, a sealed container, an intake path formation, an exhaust path formation, and a generation mechanism, said battery including a container, an electric cell of a sodium-sulfur battery, and a charging/discharging path inside the battery, said container including an outer wall and a heat transfer wall, an electric cell chamber and an air chamber being formed inside said container, said heat transfer wall dividing said electric cell chamber and said air chamber, and said electric cell and said charging/discharging path inside the battery being housed in said electric cell chamber, said charging/discharging path outside the battery and said charging/discharging path inside the battery being electrically connected to each other;
said sealed container housing said battery and said charging/discharging path outside the battery;
an intake path which starts from outside of said sealed container and leads to said air chamber being formed in said intake path formation;
an exhaust path which starts from said air chamber and leads to outside of said sealed container being formed in said exhaust path formation;and said generation mechanism generating an air flow which sequentially flows through said intake path, said air chamber, and said exhaust path; (b) determining whether or not cooling of said electric cell chamber is required; and (c) controlling said generation mechanism such that said air flow is generated in a case where it is determined that the cooling of said electric cell chamber is required, and said air flow is not generated in a case where it is determined that the cooling of said electric cell chamber is not required.
