본 고안은 전지의 집전체와 전지의 단자를 연결하는 구조에 관한 것으로, 특히 전기자동차에 사용되는 전지의 집전체와 단자를 연결할 때 서로 접촉되는 면적을 일정하게하여 전지의 수명을 증대시킨 전지의 집전체와 단자 연결구조에 관한 것이다.The present invention relates to a structure for connecting the current collector of the battery and the terminal of the battery, and in particular, when the current collector and the terminal of the battery used in an electric vehicle are connected to each other to maintain a constant area of the battery of the battery It relates to a current collector and a terminal connection structure.

일반적으로, 기존의 재연기관 차량은 배기가스중에 함유된 질소산화물, 탄화수소, 일산화탄소등과 같은 배출가스에 의해 환경을 오염시킬뿐만 아니라 에너지원이 석유자원에만 의존하게 되어 제한된 석유 매장량에 대한 고갈이 염려되고 있다.In general, existing reburn engine vehicles not only pollute the environment by the exhaust gases such as nitrogen oxides, hydrocarbons, carbon monoxide, etc. contained in the exhaust gas, but the energy source is dependent only on the petroleum resources, and there is concern about exhaustion of limited oil reserves. It is becoming.

따라서, 현재에는 환경 오염 방지 및 에너지원의 다양화를 위해 전기자동차가 개발되고 있다.Therefore, electric vehicles are currently being developed to prevent environmental pollution and to diversify energy sources.

그리고, 이러한 전기자동차는, 기존의 내연기관 차량이 원류로부터 차량의 운동에너지로 변환될 때 까지의 에너지 효율이 약 10.3%인데 반해, 17.8%로 약 70%정도 효율이 높아 경제성이 있으며 기존의 내연기관 자동차에서 문제가 되는 대기 오염 및 소음 공해 등과 환경문제를 해결할 수 있을 뿐만 아니라 심야 잉여전력을 개발할 수도 있다.In addition, the electric vehicle has an energy efficiency of about 70% at 17.8%, compared to 10.3% of the energy efficiency of the existing internal combustion engine vehicle from the main stream to the kinetic energy of the vehicle. In addition to solving environmental problems such as air pollution and noise pollution, which are a problem in the locomotive cars, it is possible to develop late-night surplus power.

그러나, 현재까지 개발된 전기자동차는 내연기관 자동차의 성능에 비해 일층전 주행거리가 짧을 뿐만 아니라 가속, 등판, 최고속도 등의 성능이 뒤떨어지고, 적재량, 객실용량 등이 부족한 점들 때문에 현재까지는 보편, 실용화되지 못하고 있다.However, the electric vehicles developed to date have not only shorter mileage than the performance of internal combustion engine cars, but also have poor performance such as acceleration, climbing, and top speed, and lack of loading capacity and cabin capacity. It has not been put to practical use.

이러한 문제점을 주로 전기자동차에 탑재되는 전지의 성능에 관계되는 것으로, 전지의 성능은 각 중량당 어느 정도의 성능을 나타내는가로 비교하게 되며, 일반적으로 출력밀도(W/Kg) 및 에너지 밀도(Wh/Kg)로 나타낸다.These problems are mainly related to the performance of batteries installed in electric vehicles. The performance of the batteries is compared by how much the performance shows for each weight. In general, the power density (W / Kg) and the energy density (Wh / Kg).

즉, 자동차의 성능을 향상시키기 위한 전지 측면에서의 과제는 출력밀도 및 에너지 밀도를 증가시키는 것이다. 또한, 전기자동차의 전지의 경우 성능뿐만 아니라 유지관리 측면도 고려하여야 한다. 즉, 충전시간이 짧아야 하며, 충전시 안전하게 충전할 수 있어야 하고 아울러 장시간 사용할 수 있어야 하는 것이다.That is, the problem in terms of a battery for improving the performance of an automobile is to increase the power density and the energy density. In addition, in the case of batteries of electric vehicles, consideration should be given to maintenance as well as performance. That is, the charging time should be short, it should be able to charge safely when charging, and also be able to use for a long time.

한편, 이러한 전기자동차용 전지에 있어서, 종래에는 전지의 단자와 집전체들을 용접하여 연결하는 방법을 사용하였다.On the other hand, in such a battery for electric vehicles, a method of welding and connecting the terminals of the battery and the current collector was conventionally used.

그러나, 하내의 전지에 집전체의 개수가 20여개나 되므로 집전체를 단자에 균일하게 용접하기가 매우 어려워 단자와 집전체 간의 접촉 면적이 일정하지 못하게 되고, 따라서 접촉 저항이 불균일하게 되고 전지의 성능 또한 불균일하게 되는 것이다.However, since there are about 20 current collectors in a battery, it is very difficult to uniformly weld the current collector to the terminals, so that the contact area between the terminal and the current collector becomes inconsistent, resulting in uneven contact resistance and performance of the battery. It also becomes uneven.

또한, 여러개의 집전체가 단자에 용접됨에 따라 일부 집전체가 단자에 견고하게 용접되지 않아 전지 수명이 단축되는 문제점이 있었다.In addition, as a plurality of current collectors are welded to the terminals, some current collectors are not welded to the terminals firmly, thereby reducing battery life.

따라서, 본 고안은 상기와 같은 종래의 제 문제점을 해소하기 위한 것으로, 전기자동차에 사용되는 전지의 집전체와 전지의 단자를 연결할 때 서로 접촉되는 면적을 일정하게하여 전지의 수명을 증대시킨 전지의 집전체와 단자 연결구조를 제공하는데 그 목적이 있다.Accordingly, the present invention is to solve the above-mentioned problems of the prior art, and the constant contact area when connecting the current collector of the battery and the terminal of the battery used in the electric vehicle to increase the life of the battery of the battery The purpose is to provide a current collector and terminal connection structure.

이러한 목적을 달성하기 위한 본 고안에 따른 전지의 집전체와 단자 연결구조는, 단자의 양측면에 집전체들이 각각 위치되고, 상기 집전체들의 외측에는 스트립이 각각 위치되는 한편, 상기 각 스트립이 보울트와 너트에 의해 단자에 밀착 결합되어 상기 집전체가 단자에 밀착 고정되는 구조로 되어, 집전체와 전지가 서로 접촉되는 면적이 일정해짐에 따라 전지의 수명을 증대되는 것이다.The current collector and the terminal connection structure of the battery according to the present invention for achieving this purpose, the current collector is located on both sides of the terminal, respectively, the strip is located on the outside of the current collector, while each of the strip and the bolt The nut is tightly coupled to the terminal so that the current collector is tightly fixed to the terminal. As the area where the current collector and the battery contact each other becomes constant, the life of the battery is increased.
