일반적으로 세계적인 환경 규제 강화와 에너지 절감 추세에 따라 세계각국에서는 친환경적인 자동차의 개발과 보급이 점차적으로 확산되고 있는 추세이다. 한편 전기자동차는 순수하게 외부에서 전기에너지를 충전한 배터리만으로 운행하는 순수 전기자동차(EV, Electric Vehicle), 엔진 및 모터를 사용하는 하이브리드 자동차(HEV, Hybrid Electric Vehicle), 외부 전원으로부터 충전 가능한 플러그인 하이브리드 자동차(PHEV, Plug-inHybrid Electric Vehicle) 등을 포함할 수 있다.In general, the development and distribution of eco-friendly vehicles is gradually spreading around the world in accordance with the strengthening of global environmental regulations and energy saving trends. Meanwhile, electric vehicles include pure electric vehicles (EV, Electric Vehicle) that run purely on batteries charged with electrical energy from outside, hybrid vehicles (HEV, Hybrid Electric Vehicle) that use an engine and motor, and plug-in hybrids that can be charged from an external power source. It may include automobiles (PHEV, Plug-in Hybrid Electric Vehicle), etc.
최근 우리나라에서도 정부의 환경 규제 강화로 인하여, 차량 제조업체는 고연비 및 CO2 배출량이 적은 EV(Electric Vehicle) 및 PHEV(Plug-in Hybrid Electric Vehicle) 등의 친환경 전기자동차량 개발에 박차를 가하고 있는 상황이며, 이러한 전기자동차의 보급에 따라 충전을 위한 충전소의 확충 및 충전용 케이블의 보급이 필요한 상황이다.Due to the recent strengthening of environmental regulations by the government in Korea, vehicle manufacturers are accelerating the development of eco-friendly electric vehicles such as EV (Electric Vehicle) and PHEV (Plug-in Hybrid Electric Vehicle) with high fuel efficiency and low CO2 emissions. With the spread of electric vehicles, there is a need to expand charging stations and supply charging cables.
한편, 전기자동차를 충전하기 위한 충전소의 경우 충전스탠드에 연결된 전기차 충전용 케이블과 커넥터를 차량의 인렛(inlet)에 꽂아 연결함으로써 상기 인렛을 통해 전기적으로 연결된 전기차 내부의 배터리팩 충전이 시작된다. Meanwhile, in the case of a charging station for charging an electric vehicle, the electric vehicle charging cable and connector connected to the charging stand are plugged into the inlet of the vehicle to start charging the battery pack inside the electrically connected electric vehicle through the inlet.
이러한 전기자동차 충전 시스템에 이용되는 통상의 충전용 케이블은 충전용 전력 유닛 또는 통신 유닛 등 각종 코어들을 쉬스층이 전체적으로 감싼 형태로 이루어진다.A typical charging cable used in such an electric vehicle charging system is made up of a sheath layer covering various cores, such as a charging power unit or a communication unit.
또한, 상기 충전용 케이블에 의해 충전되는 차량 내부의 배터리팩은 주로 리튬 이차전지를 이용하고 있으며, 이러한 리튬 이차전지를 겹겹이 쌓아 전기적으로 직렬 및/또는 병렬로 연결한 배터리 모듈을 외부 충격이나 방습을 위해 금속 재질의 케이스 내부에 수납한 형태로 구성된다.In addition, the battery pack inside the vehicle charged by the charging cable mainly uses lithium secondary batteries, and the battery modules in which these lithium secondary batteries are stacked and electrically connected in series and/or parallel are protected from external shock and moisture. It is constructed to be stored inside a case made of metal.
그러나, 상기 리튬 이차전지를 이용한 배터리팩은 복수의 배터리 모듈이 열폭주에 의해 발화 내지 폭발할 가능성이 있으며, 이로 인해 인접한 이차전지로 열 또는 화염이 전달되어 2차 발화 내지 폭발이 일어날 경우에는 인명피해를 동반한 매우 심각한 상황을 초래할 수 있기 때문에 이러한 2차 발화 내지 폭발을 방지하기 위한 소화 기술의 개발이 활발히 이루어지고 있다.However, in a battery pack using the lithium secondary battery, there is a possibility that a plurality of battery modules may ignite or explode due to thermal runaway, and as a result, heat or flame is transferred to adjacent secondary batteries and secondary ignition or explosion occurs, resulting in death. Since this can lead to a very serious situation accompanied by damage, fire extinguishing technology is being actively developed to prevent secondary ignition or explosion.
일례로, 한국 공개특허 제2021-0017535호(명칭: ‘소화 유닛을 포함한 배터리 팩’, 이하 ‘선행특허’라 함)에는 배터리팩 내부에서 열폭주가 발생되는 경우 차량 내부에 탑재된 소화 탱크 등의 소화 유닛으로부터 배터리팩 내부로 소화약제를 자동으로 주입하는 기술이 개시되어 있다.For example, Korean Patent Publication No. 2021-0017535 (name: 'Battery pack including fire extinguishing unit', hereinafter referred to as 'prior patent') discloses that in case thermal runaway occurs inside the battery pack, a fire extinguishing tank mounted inside the vehicle, etc. A technology for automatically injecting fire extinguishing agent into the battery pack from the fire extinguishing unit is disclosed.
그러나, 상기 선행특허에 개시된 기술은 소화 탱크를 포함한 소화 유닛을 차량 내부의 배터리팩 주변에 항상 탑재하여야 하므로 상기 소화 유닛에 의해 차량의 중량이 증가될 뿐만 아니라, 상기 소화 유닛이 배터리팩의 점유공간을 상당 부분 차지하게 되므로 결국 차량의 연비 및 주행거리에 악영향을 미치는 문제점이 발생되었다.However, in the technology disclosed in the prior patent, a fire extinguishing unit including a fire extinguishing tank must always be mounted around the battery pack inside the vehicle, so not only does the fire extinguishing unit increase the weight of the vehicle, but the fire extinguishing unit also requires the space occupied by the battery pack. Since it occupies a significant portion of the vehicle's fuel efficiency and driving distance, problems have arisen that have a negative impact on the vehicle's fuel efficiency and driving distance.
뿐만 아니라, 소화 유닛의 오작동으로 인해 배터리팩 내부로 소화약제가 잘못 분사된 경우에는 주행 중인 차량이 정지되어 심각한 사고를 유발할 수 있으며, 또한 소화약제의 제거 및 배터리팩의 복구를 위해 배터리팩을 전면 교체해야 할 수도 있으므로 이로 인해 상당한 경제적 손실이 야기되는 문제점이 있었다.In addition, if the extinguishing agent is incorrectly sprayed into the battery pack due to a malfunction of the fire extinguishing unit, the running vehicle may stop and cause a serious accident. In addition, the battery pack must be turned over to the front to remove the extinguishing agent and restore the battery pack. Since it may need to be replaced, there was a problem that caused significant economic loss.
