Description

Electric vehicle charging station firefighting equipment

The present invention relates to firefighting equipment at an electric vehicle charging station, and more specifically, to firefighting equipment at an electric vehicle charging station that can respond quickly when an electric vehicle battery fire occurs when charging an electric vehicle.

Recently, research and investment on reducing carbon dioxide emissions from vehicles using fossil fuels has been actively conducted, especially in major developed countries around the world.

Representative projects include EV (Electric Vehicle), HEV (Hybrid Electric Vehicle), PHEV (Plug-in Hybrid Electric Vehicle), and FCEV (Fuel Cell Electric Vehicle).

Hereinafter, EV, HEV, PHEV, FCEV, etc. are collectively referred to as electric vehicles (EV).

Interest in and investment in the electric vehicle (EV) business is active not only in the government but also in the private sector, and major domestic and foreign automobile manufacturers, battery manufacturers, and EVSE (Electric Vehicle Supply Equipment) manufacturers are producing higher quality products. We are developing a product.

In general, electric vehicles play a role as a means of transportation by driving a motor with power from a battery to ensure driving performance above a certain vehicle speed.

These electric vehicles were developed as a measure to reduce exhaust gases, and have the advantage of low noise and no exhaust gases. They are pollution-free vehicles that usually drive an electric motor with electrical energy and rotate the wheels through a power transmission device. As such, a battery is used as a power source required for driving force.

A number of such batteries are installed on the bottom of the car, and each battery is connected in series or parallel to create the appropriate voltage required for the electric motor.

As the number of electric vehicles using batteries is increasing, fire incidents involving electric vehicles are also increasing.

There are two main scary things about electric vehicle battery fires.

The first is that the fire starts at the same time as the collision and spreads quickly enough to spread throughout the entire car in an instant. This is due to the battery thermal runaway phenomenon.

Second, it is difficult to extinguish an electric vehicle battery fire because the battery package is covered with iron, so fire extinguishing agents cannot penetrate.

If a battery thermal runaway occurs, the entire electric vehicle must be placed in a huge water tank or a temporary wall must be built around the electric vehicle to surround the entire battery with water.

However, as mentioned above, at charging stations for charging electric vehicles, it is realistically difficult to provide a water tank to put the entire electric vehicle in in the event of a battery fire, and it takes a lot of time and manpower to build a temporary wall around the electric vehicle and surround the entire battery with water. There is a problem.

The present invention was developed to solve various problems in the prior art as described above. If a fire occurs in an electric vehicle battery when charging an electric vehicle, the present invention can automatically detect the fire and submerge the entire electric vehicle battery in water to quickly respond to the fire. The purpose is to provide firefighting equipment at electric vehicle charging stations.

Another object of the present invention is to provide firefighting equipment at an electric vehicle charging station that does not require a separate water tank into which the entire electric vehicle can be placed in when a fire occurs in the electric vehicle battery.

Another object of the present invention is to eliminate the need for tasks such as putting the electric car into a water tank using a separate device or erecting a temporary wall around the electric car so that the entire electric car battery is submerged in water in the event of an electric car battery fire. The goal is to provide electric vehicle charging station firefighting equipment.

In order to achieve the above objectives, the present invention is an electric vehicle charging station firefighting equipment that automatically detects the fire when an electric vehicle battery fire occurs when charging an electric vehicle and submerges the entire electric vehicle battery in water.

An electric vehicle charging station fire-fighting equipment is provided, characterized in that it includes a fire-fighting device unit configured to receive water inside and submerge the entire electric vehicle battery in water.

The firefighting device unit is formed in the form of a plate with a predetermined length and a predetermined width so that an electric vehicle can be parked, and a plurality of inflators are installed at predetermined intervals along the circumference of the edge portion, and the inflator operates in the edge portion. As a result, it may include a parking stand in which an air tube that expands upward and forms a water tank is installed.

A plurality of water inlet holes penetrating up and down are formed on the surface of the parking lot where the electric vehicle is parked, and the fire fighting device unit may include a simultaneous opening valve where the other end of a water pipe is watertightly connected to the water inlet hole. You can.

The simultaneous opening valve is preferably connected to one or more of an indoor fire hydrant facility, a fire pump vehicle, a mobile fire pump, or a fixed fire pump, and a fire alarm signal is generated when the simultaneous opening valve is opened.

The parking stand may be provided with a fire detection sensor consisting of one or more of a temperature sensor that detects a temperature increase in the event of a fire, a flame sensor that detects a flame, and a smoke sensor that detects smoke.

It is preferable that the edge of the parking stand is located on the same plane as the ground, and the surface of the parking stand where the electric car is parked is stepped from the edge by a predetermined depth and buried in the ground.

The electric charging unit includes a fire recognition unit that receives a signal about the fire detected in the parking stand when a fire occurs in the electric vehicle battery; and a system control unit that receives a signal from the fire recognition unit and controls the fire-fighting device unit to operate. When the fire recognition unit recognizes a fire, the system control unit may terminate electrical charging of the electric charging unit.

The electric charging unit may include a wireless communication unit that receives a signal about a fire from the system control unit and reports the fire through wireless communication or contacts an electric charging station manager or an electric vehicle owner.

A pair of parking bumps may be formed side by side on the surface where the electric car is parked so that the electric car can be parked correctly on the parking stand.

The air tube is preferably made of suffocating fire extinguishing cloth or fire prevention cloth.

Laser scoring may be performed on the upper inner surface of the edge portion where the air tube is installed so that the air tube can be well deployed upward as the inflator operates when a fire is detected.

The electric vehicle charging station firefighting equipment according to the present invention automatically detects the fire when an electric vehicle battery fire occurs when charging an electric vehicle and submerges the entire electric vehicle battery in water, thereby quickly responding to the fire and preventing secondary damage from the fire. There are advantages to doing this.

The electric vehicle charging station firefighting equipment of the present invention may be configured to include an electric charging unit 10 and a firefighting device unit 20.

The electric charging unit 10 is one in which one or more electric chargers for charging electric vehicles are installed, and these electric chargers can be classified according to charging speed and installation type.

In other words, electric vehicle chargers are divided into fast chargers and slow chargers depending on the charging speed.

In the case of the slow charging method, it is commonly adopted by the United States, Japan, and Korea, causing little inconvenience to electric vehicle manufacturers and users, while the fast charging method is different for each country and manufacturer, so a competition for standardization is underway.

Additionally, electric vehicle chargers can be classified into wall-mounted chargers, stand-type chargers, and mobile chargers depending on the installation type.

Wall-mounted chargers and stand-type chargers have a capacity of 3 to 7 kW, and charging time takes about 4 to 6 hours.

The mobile charger has a capacity of up to 3 kW and charging time is approximately 6 to 9 hours.

Such an electric charging unit 10 includes a fire recognition unit (F) that receives a signal about the fire detected by the parking stand 21 of the firefighting device unit 20, which will be described later, when a fire occurs in the electric vehicle battery, and a fire recognition unit. It may include a system control unit (C) that receives signals from the unit (F) and controls the firefighting device unit 20 to operate.

At this time, the fire recognition unit (F) determines whether a fire has occurred through the received signal (information) about the fire. If the fire recognition unit (F) recognizes it as a fire, the system control unit (C) )'s electrical charging can be terminated.

In addition, the electric charging unit 10 is a wireless communication unit (T ) may include.

Accordingly, if an electric vehicle battery fire occurs when charging an electric vehicle, the fire is automatically detected and a quick response is made, thereby preventing secondary damage caused by a battery fire.

In this way, a fire recognition unit (F), a system control unit (C), and a wireless communication unit (T) may be disposed in the electric charging unit 10.

The firefighting device unit 20 is located on one side of the electric charging unit 10 installed in a stand type, and when an electric vehicle is parked and a fire occurs in the electric vehicle battery, the fire extinguishing device unit 20 detects the fire and the edge located around the parked electric vehicle protrudes upward. After forming the water tank, water can be supplied into the water tank from the outside so that the entire electric vehicle battery is submerged in water.

Specifically, the firefighting device unit 20 is configured to include a parking stand 21 formed in the form of a rectangular flat plate with a predetermined length and a predetermined width so that an electric vehicle can be parked.

The parking lot 21 is preferably formed to have a size of 5 m × 2.5 m. (Refer to the Ministry of Land, Infrastructure and Transport Parking Lot Act Enforcement Rules)

A plurality of inflators P are installed at predetermined intervals along the perimeter of the edge portion 21a of the parking stand 21.

An inflator (P) generally refers to a gas generating device, and inflates an air tube (AT), which will be described later, with nitrogen gas produced by instantly combusting a gas generating agent (generally sodium nitrite) using an ignition device.

The operating principle of the inflator (P) is the same as that of an airbag, except that it operates by receiving a signal when a fire is detected by the fire detection sensor (S), so a detailed description thereof will be omitted.

In addition, an air tube (AT) is installed in the edge portion 21a of the parking stand 21 and expands upward as the inflator P operates to form a water tank.

In this way, the height of the water tank formed by the air tube (AT) is preferably 0.5 m, and the required volume of this water tank is approximately 6.25 ㎥.

Therefore, the water discharge amount that fills the water tank formed by the air tube (AT) within 5 minutes is:

6.25㎥/5min (minute) = 1.25㎥/min = 1,250ℓ/min.

At this time, the air tube is preferably formed of suffocating fire extinguishing cloth or fire prevention cloth.

These suffocation fire extinguishers or fire extinguishers include uncoated or low-coated glass fiber silica fabric, silicone-coated glass fiber silica fabric, eco-friendly flame retardant resin-coated silica fabric, glass fiber-coated polytetrafluoroethylene (PTFE) sewing thread, metal sewing thread, etc. can be formed.

Laser scoring ( laser scoring) can be processed.

Laser scoring is an operation to create a passage through which the air tube (AT) located within the edge portion 21a of the parking stand 21 can be easily deployed when a fire is detected.

Along the perimeter of the rim 21a of the parking stand 21, a predetermined machine engraves a rectangular dotted line on the inner surface of the rim 21a of the parking stand 21, through which the air tube (AT) can penetrate. There will be.

In addition, a plurality of water inlet holes (H) penetrating up and down are formed on the surface of the parking stand (21) where the electric vehicle is parked, and one end of a water pipe (WT) is formed in these plurality of water inlet holes (H). It is connected watertight.

It is preferable that about 10 such water inlet holes (H) are formed at predetermined intervals over the entire area of the flat parking stand 21, and these 10 water inlet holes (H) are provided with 10 water pipes (WT). Each is connected.

Meanwhile, the firefighting device unit 20 may include a simultaneous opening valve 23 to which the other end of the water pipe WT is watertightly connected.

It can be.

Among these fire detection sensors (S), in the case of a flame sensor, it is desirable to employ a UV sensor or an IR sensor that detects a wide location through the light wavelength of the fire.

In this way, when a fire is detected by the fire detection sensor (S), the fire detection sensor (S) transmits a signal to the fire recognition unit (F), the fire recognition unit (F) recognizes the fire, and then the system control unit (C) ), and the system control unit (C) terminates the electric charging and sends a signal to the firefighting device unit (20) to extinguish the fire.

Meanwhile, the edge portion 21a of the parking stand 21 is located on the same plane as the ground, and the surface of the parking stand 21 where the electric car is parked is stepped from the edge portion 21a by a predetermined depth and is buried in the ground.

In addition, a pair of parking ridges 21b may be formed side by side on the surface of the parking stand 21 where the electric car is parked so that the electric car can be parked correctly on the parking stand 21.

The firefighting device unit 20 of the electric vehicle charging station firefighting equipment according to the present invention may include a simultaneous opening valve 23, one end of which is formed in the water inlet hole H (parking stand 21). ) The other end of the water pipe (WT) is watertightly connected.

Such a simultaneous opening valve 23 may be connected to one or more of an indoor fire hydrant facility 25, a fire pump car, a mobile fire pump, or a fixed fire pump.

At this time, when the simultaneous opening valve 23 is opened, a fire (alarm) signal is generated so that the manager of the electric charging station can recognize it.

The electric vehicle driver parks the electric vehicle in the parking stand 21 of the firefighting device unit 20 to charge it at the electric vehicle charging station, and then, while charging the electric vehicle, the fire detection sensor S installed in the parking stand 21 detects an electric vehicle battery fire. When detected, the fire detection sensor (S) transmits a signal to the fire recognition unit (F), which recognizes the fire and then transmits the signal to the system control unit (C).

The system control unit (C) terminates the electric charging and operates the inflator (gas generator) (P) built into the edge portion (21a) of the parking stand (21) of the firefighting device unit (20) to generate nitrogen gas. As the air tube (AT) inflates, it expands to a predetermined height along the perimeter of the edge portion (21a) of the parking stand (21).

When the air tube (AT) is deployed in this way to form a water tank, the system control unit (C) opens the simultaneous opening valve (23), and the indoor fire hydrant facility (25) operates, filling the water tank (fire water). will be supplied.

At this time, as the indoor fire hydrant equipment 25 opens the simultaneous opening valve 23, the pressure drops and the pump operates.

Accordingly, the water tank is filled with water to a predetermined height, and the electric vehicle battery is submerged in water, making it possible to extinguish the battery fire.

Meanwhile, while water is supplied into the water tank, the system control unit (C) generates a fire (alarm) signal to alert electric vehicle charging station managers or drivers charging electric vehicles to take necessary action quickly. .

The electric vehicle charging station firefighting system according to the present invention may be configured to include an electric charging unit 10, a firefighting device unit 20, a fire recognition unit (F), a system control unit (C), and a wireless communication unit (T).

A fire recognition unit (F), a system control unit (C), and a wireless communication unit (T) may be disposed in this electric charging unit 10.

In addition, the electric charging unit 10 may be further provided with a video camera unit (not shown). If a fire occurs in the electric vehicle battery and the fire recognition unit (F) recognizes it as a fire, the video camera unit can capture the fire situation. It is configured to film the situation at the scene of a fire and report the fire to public institutions such as the fire department through the wireless communication department (T), or transmit the video to the electric charging station manager or electric vehicle owner to check the situation at the scene of the fire in real time. .

The firefighting device unit 20 is located on one side of the electric charging unit 10, where the electric vehicle is parked, and a fire detection sensor (S) is installed to detect a fire when a fire occurs in the electric vehicle battery. is done to suppress.
