본 발명은 1차 및 2차 전지의 정격용량을 표시하는 소자에 관할 것으로서, 특히 전압이나 전류변화에 의해 물질의 색이 가역적으로 변색하는 전기 변색성(Electrochromic property)을 이용하여 전지의 정격용량을 확인할 수 있는 표시소자에 관한 것이다.The present invention relates to a device for displaying the rated capacity of the primary and secondary batteries, in particular the rated capacity of the battery using an electrochromic property (reversible discoloration of the color of the material due to voltage or current changes) It relates to a display element that can be confirmed.

주지와 같이 전지는 1차 전지와 2차 전지로 대분된다.As is well known, a battery is divided into a primary battery and a secondary battery.

1차 전지는 일단 방전해버리면 외부로부터 에너지를 공급하더라도 원래의 상태로 되돌아가지 않는 전지로서 대표적으로 건전지, 다니엘 전지, 르클랑세전지, 공기전지등이 있다.Primary batteries, once discharged, do not return to their original state even when energy is supplied from the outside. Representative batteries include batteries, Daniel batteries, Leclanuse batteries, and air batteries.

이에 반하여 2차 전지는 방전이 끝난 전지에 외부로부터 전력을 공급하여 충전함으로써 다시 방전시킬 수 있는 전지로서 대표적으로 연축전지와 알칼리축전지 등이 있다.On the contrary, the secondary battery is a battery which can be discharged again by supplying electric power to the discharged battery and charging it from the outside, and examples thereof include a lead acid battery and an alkaline storage battery.

이러한 전지의 정격용량(직류전압)을 측정하는 종래의 기술수단은 별도로 직류전압을 체크할 수 있는 테스터 등의 계측기로서 사용자가 일일이 측정해야만 하므로 계측작업이 매우 번거롭고, 만일 계측기를 구비하고 있지 못한 경우에는 전지의 사용수명을 정확히 확인할 수가 없기 때문에 사용이 가능한 전지인 경우에도 폐기 처분하는 사례가 빈번하여 자원낭비는 물론 쓰레기 폐기물의 증가를 초래하는 문제점이 야기되었다.The conventional technical means for measuring the rated capacity (direct current voltage) of such a battery is a measuring instrument, such as a tester that can check a DC voltage separately, so that the measurement is very cumbersome because the user has to measure it individually. Since the service life of the battery can not be accurately identified, even if the battery can be used, there are frequent cases of disposal, causing a problem that causes not only waste of resources but also increase of waste.

본 발명은 이러한 종래의 문제점을 해소코자 하여 제안된 것으로서, 구조가 간단하면서도 전기 변색성을 이용한 표시소자로서, 별도의 계측기를 사용하지 않더라도 전지의 정격용량을 보다 용이하게 확인할 수 있도록 함을 목적으로 한 것이다.The present invention has been proposed to solve such a conventional problem, and has a simple structure and a display device using electrochromic properties for the purpose of making it easier to check the rated capacity of a battery without using a separate measuring instrument. It is.

상기한 목적 달성을 위한 본 발명을 첨부한 도면에 의거하여 상술하면 다음과 같다.On the basis of the accompanying drawings the present invention for achieving the above object is as follows.

제1도 및 제2도에 나타낸 바와 같이 ITO소재의 투시창(1)후면에 상온조건에서 투명전극(Transparent Elctrode)(2)을 피복한 후 그 후면에 텅그스텐 옥사이드(WO3), 폴리피롤즈(polypyrroles), 폴리디오펜즈(polythiophenes), 폴리아니린(poly Aniline)중 한가지를 선택하여 이루어진 변색표시박막(3)을 부착하고 그 후면에 고체 전해질(4)을 피착한 후 전극(5)을 부착하여 구성된 것이다.As shown in FIG. 1 and FIG. 2, a transparent electrode (2) is coated on the rear surface of the viewing window (1) of ITO material at room temperature, and then tungsten oxide (WO 3 ) and polypyrroles ( Discoloration display thin film 3 formed by selecting one of polypyrroles, polythiophenes, and poly aniline is attached, and a solid electrolyte 4 is deposited on the back, and then electrode 5 is attached. It is composed.

이와 같이 구성된 본 발명의 동작 및 작용효과를 제3도를 참조하여 설명하면 다음과 같다.Referring to Figure 3 the operation and effect of the present invention configured as described above are as follows.

먼저 전지(BT)에 본 발명의 표시소자를 부착하게 되면, 전지(BT)의 케이스 자체가 (+) 또는 (-)극성을 가지고 제조되므로 제2도에 나타낸 바와 같이 투시창(1)의 후면에 피복되어 있는 투명전극(2)과 전극(5)상이에 전지(BT)가 접속된 상태가 된다.First, when the display element of the present invention is attached to the battery BT, the case itself of the battery BT is manufactured with a (+) or (-) polarity, so as shown in FIG. The battery BT is connected between the covered transparent electrode 2 and the electrode 5.

전술한 바와 같이 전기 변색성(Electrochromic property)이란 인가된 전압이나 전류의 변화에 따라 물질의 색이 가역적으로 변색하는 성질로서 전기화학적 또는 전자적인 현상에 의해 변색물질이 액체 또는 고체상태에서 산화로부터 환원반응에 따라 색변화를 일으키는 현상으로 의미하는 것이다.As described above, electrochromic property is a property in which a color of a material is reversibly changed in response to a change in an applied voltage or current, and the color change is reduced from oxidation in a liquid or solid state by an electrochemical or electronic phenomenon. It means a phenomenon that causes a color change according to the reaction.

이러한 배경하에 예로서 1차 전지가 정격전압을 유지하다가 장시간 사용으로 1차 전지에 함유되어 있는 전기 변색성 물질이 산화됨에 따라 정격전압 이하로 하강되면 다시 환원상태가 되어 일정한 색변화 현상을 일으키게 된다.Under this background, for example, the primary battery maintains the rated voltage, but when the electrochromic material contained in the primary battery is oxidized by prolonged use, the primary battery is reduced to less than the rated voltage, thereby causing a reduced color change. .

즉 제3도에 나타낸 바와 같이 초기 정격전압(E1)이 일정시간 사용에 의해 정격전압 이하의 전압(E2)으로 하강하게 되면 그 사이에 파장이 일정한 주기로 변화되어 제1도에 나타낸 투시창(1)을 통해 표출되는 색이 변색되어 나타나게 된다.That is, as shown in FIG. 3, when the initial rated voltage E 1 falls to the voltage E 2 below the rated voltage by using a predetermined time, the wavelength is changed at regular intervals therebetween, so that the viewing window shown in FIG. The color expressed through 1) will appear discolored.

한편, 재충전이 가능한 2차 전지가 소모전압(E2) 으로부터 충전되기 시작하여 만충전 전압(E1)에 도달하는 사이에도 파장이 일정한 주기로 변화되므로 이 경우에도 투시창(1)을 통해 표출되는 색이 변색되어 나타나게 된다.On the other hand, since the rechargeable secondary battery starts to be charged from the power consumption voltage E 2 and reaches the full charge voltage E 1 , the wavelength is changed at a constant cycle, so that the color expressed through the see-through window 1 also in this case. Will appear discolored.

예로서, 전압에 대한 파장비를 고려하여 전지가 정격전압 이하로 하강되어 사용불가능 레벨 전압에 도달하였다고 가정하면 투시창91)을 통해 적색이 표출되고, 정격전압인 경우에는 청색, 정격전압과 사용불가능 전압레벨 사잉인 경우에는 녹색이 각각 표출되도록 하여 사용자가 투시창(1)을 통해 표출되는 색깔이 종류를 별도의 계측기를 사용하지 않더라도 육안으로 판단하여 전지의 현재 정격용량을 용이하게 식별할 수 가 있는 것이다.For example, assuming that the battery is lowered below the rated voltage to reach an unusable level voltage in consideration of the wavelength-to-voltage ratio, red is displayed through the sight window 91), and in the case of the rated voltage, blue, and the rated voltage cannot be used. In the case of voltage level singing, the green color is displayed separately so that the user can easily identify the current rated capacity of the battery by visually judging the type of color displayed through the viewing window (1) without using a separate measuring instrument. will be.

이상에서와 같이 본 발명은 전지의 전압 또는 전류의 변화에 따라 색깔이 변화되는 전지 변색성을 이용하여 각종 전지의 정격용량을 별도의 계측기를 사용하지 않더라도 투시창을 통해 용이하게 식별할 수가 있는 것이어서, 전지의 사용수명을 보다 정확히 파악할 수가 있으므로 자원낭비 및 산업쓰레기 폐기물 증대를 미연에 방지할수 있는 효과를 제공하는 것이다As described above, the present invention can easily identify the rated capacity of various batteries through a viewing window by using the color change of the battery which changes color depending on the voltage or current of the battery, without using a separate measuring instrument. It can provide a more accurate understanding of the service life of the battery, thus preventing the waste of resources and the increase of industrial waste.
