Description

Apparatus for extinguishing fire in electric mobile devices {APPRATUS AND SYSTEMS FOR EXTINGUISHING FIRES IN ELECTRIC MOBILE APPARTUS}

The present invention relates to a device for extinguishing a fire in an electric mobile device, and more particularly, to a device for extinguishing a fire in an electric mobile device capable of preventing a back flow into a user's mouth and preventing a stored bubble solution from spilling. It is about.

In general, an electric mobility device (E-mobility) is composed of a battery and a power converter, etc., unlike general internal combustion engine mobility devices. A battery is an energy storage device, and a power conversion device is a device that converts electric energy of a battery to generate a necessary driving force, and uses the electric energy to drive a pump to move an electric mobile device.

Such an electric mobile device has the advantage of being environmentally friendly, unlike conventional internal combustion engine mobile devices, but has a problem in that it is difficult to extinguish the fire when a fire occurs due to an external shock or an internal short circuit, because the battery burns down until it is completely burned.

Specifically, when a battery cell is split by a collision, etc., 'thermal runaway', that is, more heat is generated due to a short circuit of the battery, causing a chain reaction of fire, and more heat is generated in adjacent cells, leading to a chain explosion.

Therefore, since the number of electric mobility devices is expected to increase more and more in the future, there is a need for a technology capable of more quickly and effectively extinguishing the initial fire generated from the battery of the electric mobility device.
