## Abstract

A fire suppression tank of an electric vehicle charging station, includes: a tube storage part provided at a parking position of the electric vehicle charging station to surround an entering vehicle. The tube storage part includes a storage body in which a receiving groove having a certain width and depth is formed along an edge thereof, and an air injection type multi-wall tube having a central hole is fitted and accommodated in the storage body. An upper opening of the storage body is opened or closed by a cover. As air is injected into the air injection type multi-wall tube to inflate the air injection type multi-wall tube. The cover is automatically opened, so that the inflated air injection type multi-wall tube forms the tank to surround the vehicle from all sides. A battery of the electric vehicle is submerged to be stabilized by filling the tank with water.

## Claims

### Claim 1

A fire suppression tank of an electric vehicle charging station, the tank comprising:
a quadrilateral frame-shaped tube storage part provided at a parking position of the electric vehicle charging station to surround an entering vehicle,
wherein the tube storage part comprises a storage body in which a receiving groove having a certain width and depth is formed along an edge thereof, and an air injection type multi-wall tube having a central hole is fitted and accommodated in the storage body,
wherein an upper opening of the storage body is opened or closed by an opening/closing cover, and, as air is injected into the air injection type multi-wall tube to inflate the air injection type multi-wall tube, the opening/closing cover is automatically opened, so that the inflated air injection type multi-wall tube forms the tank to surround the vehicle from all sides, and
wherein a battery of the electric vehicle is submerged to be stabilized by filling the tank with water.

### Claim 2 (depends on 1)

The fire suppression tank of claim 1, wherein the opening/closing cover is coupled to the storage body via a hinge to be pivotably opened or closed, or is configured in a shape of to cover the upper opening of the storage body.
