Problems solved by technology

In addition, for batteries used in vehicles, etc., if the battery pack is excessively exposed to high temperature operation in summer, or if a large impact is applied to the battery due to an accident such as a vehicle collision, an internal short circuit may occur or the protection function may not work properly. etc., may set the battery used in the vehicle on fire
[0008] If a battery used in the above vehicles catches fire, the fire will not only damage the battery but also spread to the vehicle causing property damage and endangering the safety of persons on board the vehicle
Also, on the road, a vehicle fire can spread to other vehicles and cause traffic jams, resulting in more serious damage

Abstract

Disclosed is an apparatus for extinguishing a battery-pack fire upon the occurrence of a fire in the battery pack. The apparatus for extinguishing fire on a battery pack according to the present invention comprises: a fire detecting sensor for sensing whether or not a battery-pack fire has occurred; a fire extinguishing agent storage tank which stores a fire extinguishing agent in a space therein; and a control unit which causes the fire extinguishing agent in the fire extinguishing agent storage tank to be injected into the battery pack upon the sensing of the occurrence of a fire by the fire detecting sensor.

Description

technical field [0001] This application claims the benefit of Korean Patent Application No. 10-2011-0091376 filed in Korea on September 8, 2011 and Korean Patent Application No. 10-2012-0099794 filed in Korea on September 10, 2012, Both applications are hereby incorporated by reference in their entirety. [0002] The present invention relates to a technique for protecting a battery pack, and more particularly, to a device capable of extinguishing a fire when the battery pack catches fire. Background technique [0003] In recent years, the demand for portable electronic products such as notebook computers, cameras, mobile phones, etc. has increased rapidly, and energy storage batteries, robots, satellites, etc. are in urgent need of development. Therefore, high-performance secondary batteries that can repeatedly perform charge / discharge are actively being researched. [0004] The secondary batteries that have been commercialized at present include nickel-cadmium batteries, ...
