More specifically, when a fire occurs in the battery of an electric vehicle, the present invention relates to a fire in an electric vehicle charging area that quickly suppresses the flame and prevents the fire from spreading to adjacent vehicles. It is about proliferation prevention facilities.

According to the government's eco-friendly energy distribution policy, the distribution of domestic electric vehicles is gradually increasing, and as of 2021, the number of registered eco-friendly vehicles is expected to be 1.16 million units and 7.85 million units by 2030.

These electric vehicles are equipped with a motor, which is a driving device that drives the vehicle, and a battery that supplies power to the motor. However, fire may occur in the battery due to environmental conditions around the battery or abnormal charging or discharging of the battery. For example, an electric vehicle runs by supplying electrical energy from a high-voltage battery to an electric motor. At this time, dozens of battery cells are connected in series to generate high voltage. Therefore, if an abnormality occurs in the high-voltage wiring connected to each part due to external shock, etc., a fire may occur. Additionally, a fully charged battery has the highest energy level and can be viewed as electrically/chemically unstable, which may lead to a fire when combined with other factors. Another presumed cause of the fire is the development of high-capacity technology with high energy density to improve battery performance.

However, as mentioned above, a fire may occur in an electric vehicle while charging or parking, so if a fire occurs in an electric vehicle in a charging area installed at a gas station or underground parking lot, it may lead to a major accident. In particular, battery modules installed in electric vehicles are designed to intensively store as many batteries as possible to improve energy density, so if any one of the batteries fails and a fire occurs, thermal runaway occurs, leading to rapid fire spread.

Accordingly, there is a need for fire spread prevention equipment to prevent the spread of fire in charging areas where electric vehicles are charged, and the related art includes Korean Patent No. 10-2339405.

In this state, as shown in FIG. 13, when the control unit 710 operates the drive motor 854a of the opening and closing unit 854 and the opening and closing plate 854c of the opening and closing unit 854 is rotated to open the through hole 852a, the first 2 One side of the connection part 830 is spread by the load of the asphyxiating fire extinguishing cloth 900 and moves downward of the main body 852 through the through hole 852a, and the other side of the second connecting part 830 is moved downward by the asphyxiating fire extinguishing cloth 900. ) The asphyxiation fire extinguishing gun 900 is moved downward so that it is automatically deployed by its own weight.

In this way, the present invention can automatically deploy the asphyxiating fire extinguishing cloth (900), prevent safety accidents that occur in the process of deploying the asphyxiating fire extinguishing cloth (900), and quickly deploy the asphyxiating fire extinguishing cloth (900). Since it can be deployed, it has the effect of safely and quickly extinguishing a fire that occurs in an electric vehicle (C).

Figure 14 is a diagram illustrating a control member according to a second preferred embodiment of the present invention.

Referring to the drawings, the control member 700 includes a control unit 710, a pump driver 720, a valve driver, and an opening/closing driver 740.

The fire detection sensor 610 is installed inside the charging area (A) where the electric vehicle (C) is located or the asphyxiant fire extinguisher (900) facing the electric vehicle (C) and detects fire, for example, asphyxiant fire extinguisher. It is installed inside (900) and can be configured to generate a detection signal when smoke is detected.

When the control unit 710 receives a detection signal from the fire detection sensor 610, it controls the opening/closing actuator 740 to rotate the opening/closing unit 854 to open the through hole 852a. Then, the suffocation fire extinguishing cloth 900 is automatically deployed downward to cover the electric vehicle (C) where the fire occurred, thereby allowing suffocation fire extinguishing to proceed. Next, the control unit 710 controls the valve driving unit and the pump driving unit 720 to control the supply pump 320 to be opened, and the fire extinguishing liquid stored in the fire extinguishing tank 310 continues to flow through the suppression nozzle unit 200 to the electric vehicle ( Let it spray to C).

In addition, if a fire occurs in the electric vehicle (C), the control unit 710 is linked with the charging system (S) that controls charging of the electric vehicle (C) and automatically starts charging so that the charging system (S) does not proceed with charging. By stopping, it is possible to prevent electricity from flowing into the electric vehicle (C).

As such, the present invention is configured to safely and quickly extinguish the fire using fire extinguishing liquid along with asphyxiation extinguishment using the automatically deployed asphyxiation fire extinguishing foam 900, thereby blocking thermal runaway and minimizing fire, and preventing the fire from spreading to adjacent vehicles. It has the effect of preventing it.

Although the present invention has been described in detail in the above embodiments, it is obvious that the present invention is not limited thereto, and it is clear to those skilled in the art that various changes and modifications are possible within the scope of the technical idea of the present invention, and such changes and modifications are attached. If it falls within the scope of the claims, the technical idea should also be considered as belonging to the present invention.
