전기 자동차용 배터리 쿨링 시스템{SYSTEM FOR COOLING THE BATTERY ADOPTING ELECTRIC VEHICLES}Battery cooling system for electric vehicle {SYSTEM FOR COOLING THE BATTERY ADOPTING ELECTRIC VEHICLES}

본 발명은 전기 자동차용 배터리(battery) 쿨링 시스템(cooling system)에 관한 것으로서, 보다 상세하게는 전기 자동차용 배터리의 수명이 연장될 수 있도록 한 그 구조가 개선된 전기 자동차용 배터리 쿨링 시스템에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery cooling system for an electric vehicle, and more particularly, to an electric vehicle battery cooling system having an improved structure for extending the life of an electric vehicle battery. .

일반적으로, 자동차는 그 구동원의 종류에 따라 증기 자동차, 내연기관 자동차 및 전기 자동차로 분류되며, 이 중 전기 자동차는 내연기관 자동차의 배기가스로 인한 대기오염 문제의 심각성을 해결하기 위한 방안으로 현재 각광을 받고 있다. 이러한 전기 자동차는 전기를 그 원동력으로 하는 것으로 일반 자동차가 내연기관에서 석유계의 연료를 연소시켜 그 에너지로 주행하는 데 비해 전력(電力)으로전동기를 돌려 주행한다. 그리고 전기 자동차는 소음과 진동이 거의 없고 배기가스를 배출하지 않기 때문에 냄새도 나지 않으며 대기를 오염시키는 일이 없다.In general, automobiles are classified into steam cars, internal combustion engine cars, and electric cars according to the type of driving source, and among them, electric vehicles are currently in the limelight as a way to solve the seriousness of the air pollution problem caused by the exhaust gas of internal combustion engine cars. Is getting. Such electric vehicles use electricity as their driving force, and in general, automobiles run by rotating electric motors with electric power, compared to combustion of petroleum-based fuel in an internal combustion engine and running with the energy. And electric cars have very little noise and vibration, emit no emissions, and therefore do not smell or pollute the air.

전기 자동차는 전기에너지를 이용하여 전동기를 회전시켜 바퀴를 구동시키는 원리로 주행을 하도록 설계되며, 자동차의 주행을 위해서는 높은 전압의 전지 에너지가 필수로 되고 있다. 하지만 현재 하나의 전지로는 전기 자동차를 구동시킬 만큼 높은 전지 에너지를 얻지 못 하기 때문에 보통 다수의 전지를 직렬 또는 병렬로 접속하여 높은 전압을 얻는 동시에 긴 수명을 유지하도록 하고 있다.Electric vehicles are designed to drive on the principle of driving wheels by rotating an electric motor using electric energy, and high voltage battery energy is essential for driving a vehicle. However, since one cell does not obtain high battery energy enough to drive an electric vehicle, many batteries are usually connected in series or in parallel to obtain a high voltage while maintaining a long lifespan.

상기 다수의 전지를 모아 고정한 것을 전지팩이라 하며, 실질적으로 전기 자동차에는 이 전지팩이 몇 개씩 상부가 개방된 상자 모양의 트레이에 고정되어 차량에 탑재되고 있다.The battery pack is a collection of a plurality of batteries, and the battery pack is substantially mounted on a vehicle tray, which is fixed to a box-shaped tray in which the upper part of the battery pack is opened.

도 1에는 일반적인 전기 자동차용 배터리 쿨링 시스템의 구성을 나타낸 개략도가 도시되어 있다.1 is a schematic view showing the configuration of a battery cooling system for a general electric vehicle.

도시된 바와 같이, 복수개의 배터리(10)가 장착된 트레이(tray)(11)의 프론트(front) 및 리어(rear)에 예컨대, 상기 트레이(11)의 프론트에 두개의 쿨링팬(12)이 설치되고, 상기 트레이(11)의 리어에 네개의 쿨링팬(13)이 설치된다.As shown, two cooling fans 12 are provided at the front and rear of the tray 11 on which the plurality of batteries 10 are mounted, for example, at the front of the tray 11. Four cooling fans 13 are installed at the rear of the tray 11.

이와 같이 구성된 종래의 전기 자동차용 배터리 쿨링 시스템은, 상기 배터리(10) 충전시 모든 트레이(11)의 프론트 및 리어에 설치된 쿨링팬(12,13)이 동시에 작동하게 된다.In the conventional battery cooling system for an electric vehicle configured as described above, when the battery 10 is charged, the cooling fans 12 and 13 installed at the front and rear of all the trays 11 are operated at the same time.

동시에 모든 상기 쿨링팬(12,13)이 작동되므로 프론트의 쿨링팬(12)의 경우, 프레시 에어(fresh air)가 유입되고, 리어의 쿨링팬(13)은 상기 트레이(11) 내부의뜨거운(hot) 에어를 그 외부로 방출되도록 한다.Since all the cooling fans 12 and 13 are operated at the same time, in the case of the front cooling fan 12, fresh air flows in, and the rear cooling fan 13 is hot inside the tray 11. hot) allows air to be released out of it.

그런데, 프레시 에어가 유입되는 트레이(11)의 프론트 쪽은 온도가 높고, 뜨거운 공기를 방출하는 리어 쪽은 온도가 비교적 높게 나타난다.By the way, the front side of the tray 11 into which fresh air flows is high, and the rear side which discharges hot air is relatively high.

한편, 전기 자동차의 동력원인 배터리(10)의 수명은 온도에 의해 좌우된다. 따라서 상기 트레이(11)의 위치에 따라 온도 편차가 심하여 배터리(10)의 수명을 단축시키게 되는 요인으로 작용하게 된다.On the other hand, the life of the battery 10 that is the power source of the electric vehicle depends on the temperature. Therefore, the temperature variation is severe depending on the position of the tray 11, which acts as a factor of shortening the life of the battery 10.

본 발명은 상기와 같은 문제점을 해결하기 위하여 창출된 것으로서, 온도 편차를 배터리의 수명을 향상시킬 수 있도록 한 전기 자동차용 배터리 쿨링 시스템을 제공하는데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to provide a battery cooling system for an electric vehicle, in which a temperature deviation can improve a battery life.
