Abstract

A battery container has excellent workability, assembly, expandability, and safety. The battery container includes at least one battery rack including a plurality of battery modules; a container housing having an empty space formed therein to accommodate the battery rack; a plurality of main connectors located on at least one side of the container housing and configured to be electrically connected to the outside; and a main bus bar connected between the plurality of main connectors to transmit power.

First claim

What is claimed is:

1 . A battery container comprising:
at least one battery rack including a plurality of batteries; a container housing having:
an inner space formed therein to accommodate the at least one battery rack; and
a connector accommodation portion having a concave shape and formed on a first side of the container housing;
a first main connector located in the connector accommodation portion of the container housing on the first side of the container housing, the first main connector being configured to be electrically connected to the outside; and a main bus bar connected to the first main connector to transmit power.

2 . The battery container according to claim 1 , further comprising a second main connector located on a second side of the container housing, the second side being opposite to the first side,
wherein the main bus extends between the first main connector and the second main connector.

3 . The battery container according to claim 1 , wherein the connector accommodation portion is formed at a junction of a top wall and the first side wall of the battery container,
wherein a first cover attaches to the top wall and closes a top of the connector accommodation portion, and wherein a second cover attaches to the side wall and closes a side of the connector accommodation portion.

4 . The battery container according to claim 1 , wherein the first main connector is configured to be exposed to outside of the container housing.

5 . The battery container according to claim 1 , wherein the first main connector is located at an upper side of the container housing.

6 . The battery container according to claim 1 , wherein the connector accommodation portion is formed to be opened in upper and side directions at a top edge portion of the container housing.

7 . The battery container according to claim 1 , further comprising:
a connector cover configured to cover an outer side of the connector accommodation portion.

8 . The battery container according to claim 1 , further comprising:
a link cover configured to be coupled to a side of the connector accommodation portion and configured to surround a link bus bar connected to the first main connector.

9 . The battery container according to claim 1 , further comprising:
an air conditioning module configured to regulate the inner space of the container housing.

10 . The battery container according to claim 1 , further comprising:
a venting module configured to discharge an internal gas of the container housing to the outside.

11 . The battery container according to claim 1 , further comprising:
a firefighting module configured to supply a fire extinguishing liquid supplied from outside to the battery rack.

12 . The battery container according to claim 11 , wherein the firefighting module is configured to supply the fire extinguishing liquid supplied from the outside to another battery container.

13 . An energy storage system, comprising the battery container according to claim 1 .

14 . The battery container according to claim 1 , wherein the main bus bar is configured to transmit DC power.

15 . The battery container according to claim 1 , wherein the main bus bar is disposed in the inner space of the container housing.

16 . A battery container comprising:
at least one battery rack including a plurality of batteries; a container housing having:
an inner space formed therein to accommodate the at least one battery rack; and
a connector accommodation portion having a concave shape and formed on an upper portion of a first side of the container housing;
a first main connector located in the connector accommodation portion of the container housing on the upper portion of the first side of the container housing, the first main connector being configured to be electrically connected to the outside; and a main bus bar connected to the first main connector to transmit DC power, wherein the main bus bar is disposed in the inner space of the container housing.

17 . The battery container according to claim 16 , wherein the first main connector is further configured to be exposed to outside of the container housing.

18 . The battery container according to claim 17 , further comprising a connector cover configured to cover an outer side of the connector accommodation portion.

19 . The battery container according to claim 17 , further comprising a link cover configured to be coupled to a side of the connector accommodation portion and configured to surround a link bus bar connected to the first main connector.

20 . The battery container according to claim 18 , further comprising:
an air conditioning module configured to regulate the inner space of the container housing; a venting module configured to discharge an internal gas of the container housing to the outside; and a firefighting module configured to supply a fire extinguishing liquid supplied from outside to the battery rack.
