EV Charging Station Automatic Fire Extinguishing System
The battery of electric vehicle is a combination
of about 300pieces battery cells, and when one of the pieces catches fire, a
‘thermal runaway phenomenon’ occurs in which the fire spreads to surrounding
pieces in succession. the fire will not be extinguished until the battery is
completely combusted.
Currently, if an electric vehicle fire accident occurs, the vehicle body must be submerged in a water tank filled with water and wait for the fire to be extinguished. Just pouring water would take a lot of time and very large amount of water.
Most of the electric vehicle fire cases
occur during the charging process, and if an accident occurs in a parking lot
inside a building, especially in the basement, it is difficult and
time-consuming to place the vehicle in a flood tank, which is highly likely to
lead to a 2nd fire and large-scale fire accident.
With significantly increasing EV vehicle,
the charging stations in parking lots is also increasing, which means the
safety measures are urgently needed.

One part of SG Safety's business is the construction and operation of electric vehicle charging stations. We also developed the facilities to detect and immediately extinguish fires that may occur when charging electric vehicles. It is possible to provide a solution that simultaneously constructs charging facilities for electric vehicles and fire prevention.
EV Automatic fire extinguishing system
In response to a lithium-ion battery fire that occurs when charging an electric vehicle, a water tank is formed with heat-resistant flame-retardant fabric to inundate the battery and effectively extinguish the fire in the early stages.
EV Automatic fire extinguishing system Operation process
Detect fire
- Sensor detect the CO gas at initial stage
of fire through the pipe (operation 24 hours a day)
- When CO is detected as set value on the
control panel, immediately transmit the signal (prevent malfunction)
Raising Water tank
- Control panel detects the fire and
activate the winch motor and raise flame retardant fabric and water tanks
- Control panel stops the winch motor when
the proximity sensor detect the set height of water tank
Operating smoke ventilation
system(Optional)
- When the water tank rises after a fire is
detected, the ventilation system operates
(emission of toxic gas generated in case of
fire, applied to confined spaces such as underground parking lots)
- When the ventilation system is linked,
the water tank height should be installed up to the ceiling Injecting Fire
Fighting Water
- Operating the pump motor and discharge
the water at the same time the water tank wall rises
- Not only main water nozzle, but also
sprays water in 360-degree Omni directionally through branch pipes
- Detecting the water level at sensor,
control panel stops the pump motor
Automatic fire extinguishing system
operation principle
- Auto Mode
24-hour detect gas through sensor and
temperature with thermal imaging camera
As soon as the OFF gas is detected by the
sensor, the water tank buried at the bottom rises, and the ventilation
discharges harmful gases to the outside, and fire extinguishing water is
sprayed 360 degrees to flood the exploded vehicle
- Manual Mode
Start operation pushing the operation
switch after confirming the fire incident
The water tank rises and the ventilation
discharges harmful gases to the outside, and fire extinguishing water is
sprayed 360 degrees to flood the exploded vehicle.
