Abstract

1. 청구범위에 기재된 발명이 속한 기술분야1. TECHNICAL FIELD OF THE INVENTION

여러개의 단위셀들로 이루어진 밧데리 팩Battery pack consisting of several unit cells

2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention

밧데리 팩을 구성하는 단위셀들 중에서 사용중 발생하는 특정 단위셀의 용량미달 및 충전부족 등의 문제점을 해소하려고 하는 것임It is to solve problems such as under capacity and lack of charge of a specific unit cell, which occur during use among the unit cells constituting the battery pack.

3. 발명의 해결방법의 요지3. Summary of Solution to Invention

여러개의 단위셀을 조합하여 사용하는 밧데리 팩에 있어서, 상기 밧데리 팩의 몸체(100)를 구성하는 각각의 단위셀(1)들을 방전율에 따른 방전시험으로 단위셀(1)들을 방전용량별로 1차로 분류 및 그룹화시키는 제1공정과, 상기 제1공정을 거쳐 방전용량별로 분류된 그룹내의 수개의 단위셀(1)을 직렬로 연결하여 팩에 적용될 충전조건과 동일하게 충전시키는 제2공정과, 상기 제2공정에 의해서 충전된 단위셀(1)들에 미소전류를 인가하여 인가시의 각 단위셀(1)들의 전압을 점검 및 기록하여 전압기준별로 2차로 분류하여 그룹화시키는 제3공정으로 이루어진 것을 특징으로 한 것이다.In a battery pack using a combination of several unit cells, each unit cell (1) constituting the body 100 of the battery pack in the discharge test according to the discharge rate according to the discharge rate of the unit cells (1) primarily by discharge capacity A first step of sorting and grouping, a second step of connecting several unit cells 1 in a group classified by discharge capacity through the first step in series to charge the same as the charging condition to be applied to the pack; A third process of applying a small current to the unit cells 1 charged by the second process to check and record the voltages of the unit cells 1 at the time of application and to classify them into secondary groups according to voltage standards. It is a feature.

4. 발명의 중요한 용도4. Important uses of the invention

밧데리 팩을 구성하는 여러개의 단위셀들의 용량 및 효율을 균일화하는데 적용되는 것임It is applied to equalize the capacity and efficiency of several unit cells constituting the battery pack.
