Description

축전지 팩 조립형 밀폐 고정형 납축전지{Battery pack assembly type sealed lead acid battery}[0001] The present invention relates to a battery pack assembly type sealed lead acid battery,

본 발명은 납축전지에 관한 것으로, 밀폐 고정형 납축전지의 셀 구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a lead acid battery, and more particularly, to a cell structure of a hermetically sealed lead acid battery.

밀폐 고정형 납축전지는, 양극판에서 생성된 산소가스가 음극으로 이동하고, 음극판에서 생성된 수소가스와 결합하여 물을 생성하는 특징을 가진 축전지로, 이러한 산소재결합 과정을 통해 축전지 내의 전해액을 유지시켜 보액이 필요하지 않은 축전지이다.The closed-type fixed lead-acid battery has a feature that the oxygen gas generated from the cathode plate moves to the cathode and combines with the hydrogen gas generated in the cathode plate to generate water. Through this oxygen recombination process, the electrolyte in the battery is maintained, Is a battery that is not needed.

저용량 제품은 배터리 하나당 셀이 하나가 있는 싱글셀(single cell)방식을 사용하고, 고용량 제품은 여러개의 싱글셀이 병렬로 결합된 멀티셀(multi cell) 방식으로 제작된다. 고용량 제품은 축전지 내부가 2개 및 4개의 셀로 구성되어 있으며 각각의 셀은 칸막이로 분리되어 있고, 산소용접에 의해 각 셀이 병렬로 연결된다.A low-capacity product uses a single cell type having one cell per cell, and a high-capacity product is manufactured using a multi-cell type in which a plurality of single cells are connected in parallel. The high-capacity product consists of two cells and four cells inside the cells. Each cell is divided into cubicles, and each cell is connected in parallel by oxygen welding.

이러한 제조 방식은 멀티셀 제품에서 한 개의 셀이 이상이 생기면 다른 정상 셀까지 모두 폐기해야 하므로 불량품에 대한 폐기비용이 증가하게 된다. 또한, 제품의 용량은 극판 개수에 의해 결정되므로, 제품의 용량별로 제조 공정의 모두 다르게 되어 제조 공정에 손실이 발생하는 단점이 있다.In such a manufacturing method, if one cell is defective in a multi-cell product, all the other cells must be discarded, so that the disposal cost for defective products increases. In addition, since the capacity of the product is determined by the number of the electrode plates, there is a disadvantage in that the manufacturing process is completely different depending on the capacity of the product, thereby causing a loss in the manufacturing process.

본 발명은 기존 제품의 문제점을 개선하기 위한 것으로, 축전지 제조공정 단순화와 셀간 균일성 증대 및 불량품에 의한 비용 감소 및 제품간의 균일성을 향상 한다는 과제를 해결하고자 한다.Disclosure of Invention Technical Problem [6] The present invention aims at solving the problems of existing products, and aims to simplify the battery manufacturing process, increase the uniformity between cells, reduce costs due to defective products, and improve uniformity between products.

위와 같은 과제를 해결하기 위하여, 본 발명은, 축전지는 축전지 팩의 결합으로 구성되어 있고, 축전지 팩은, 저용량 싱글셀 구조로 양극과 음극 단자 한쌍으로 구성되어, 축전지 팩의 총 높이는 축전지 전조 높이보다 작거나 같아야 하며, 축전지 팩간의 연결은 동일한 극성의 단자끼리 부스바로 연결되며, 부스바에는 축전지 팩의 단자 개수만큼 구멍으로 구성되어 축전지 팩의 단자를 볼트로 채결할 수 있어야 하고, 축전지는, 전조에 삽입된 축전지 팩과 축전지 팩의 단자를 연결하는 부스바를 덮는 카바로 구성되며, 부스바 측면에 형성된 부스바 단자는 카바 위로 돌출된 형태의 축전지 구조를 제공한다.According to an aspect of the present invention, there is provided a battery pack including a battery pack and a battery pack. The battery pack includes a pair of positive and negative terminals in a low-capacity single cell structure. And the connection between the battery packs is made by connecting the terminals of the same polarity to each other at the booths and the bus bar should be formed with holes corresponding to the number of the terminals of the battery pack so that the terminals of the battery pack can be connected by bolts, And the bus bar terminal formed on the side of the bus bar provides a battery structure in the form of protruding over the cover.

이와 같은 본 발명은, 축전지 팩으로 결합된 축전지로 축전기 팩의 개수로 축전지의 용량을 선택 할 수 있으며, 축전지 팩의 제조 공정만 구성되면 다양한 용량의 축전지를 제조할 수 있는 제조 공정의 단순화를 확보 및 불량품에 의한 폐기비용 감소 와 제품간의 균일성을 증대할 수 있다.According to the present invention, the capacity of the battery can be selected by the number of the capacitor packs by the battery connected to the battery pack. If the battery pack is manufactured only by the manufacturing process, it is possible to simplify the manufacturing process And it is possible to reduce the disposal cost due to defective products and increase the uniformity between the products.
