본 고안은 축전지의 충방전 회로에 관한 것이다.The present invention relates to a charge / discharge circuit of a storage battery.
기존의 충방전 회로는 축전지에 충전이 완료되어도 계속 충전 전류가 인가되어 과충전되므로 축전지의 수명을 단축시킬 뿐만 아니라 축전지의 방전시에도 적당한 방전완료시기를 표시하여 주지 못하여 과방전을 행하며 충전시간이 너무 길어 사용상 크게 불편을 주는 것이었다. 본 고안은 이와 같은 점을 해소하기 위하여 축전지가 충전완료시 충전 전류를 제한하는 과충전 제어 기능과 충전 시간을 단축시킬 수 있는 충방전 회로를 제공하고 발광다이오드의 점등 여부에 따라 충방전 시기를 금방 식별할 수 있게 한 것으로 전압 비교기 및 SCR에 병렬로 접속된 저항을 사용하여 과충전을 방지하는 충전부 및 발광 다이오드 스위칭트랜지스터, 제너 다이오드를 사용하여 방전상태가 제어되는 방전부를 구성시켜 된 것이다.Existing charging and discharging circuits continue to be charged and overcharged even after the battery is fully charged, which not only shortens the life of the battery but also does not indicate the proper discharge completion time even when the battery is discharged. It was long to give great inconvenience to use. In order to solve this problem, the present invention provides an overcharge control function that limits the charging current when the battery is fully charged and a charge / discharge circuit that can shorten the charging time, and immediately identify the charge / discharge time according to whether the light emitting diode is turned on. It is possible to configure the discharge part to control the discharge state by using the charging part which prevents overcharge using the resistor connected in parallel with the voltage comparator and SCR, and the light emitting diode switching transistor and the zener diode.
이를 첨부 도면에 의하여 상세히 설명하면 다음과 같다.This will be described in detail with reference to the accompanying drawings.
본 고안은 충전 어댑터(1)에 충전부(5) 및 방전부(10)를 구성시킨 것으로 충전부(5)는 다이오드(D2)(D3)를 통하여 SCR1의 제어된 후 축전지(B)에 충전되게 구성하고 비교기(CP1)에서 제너다이오드(ZD1)의 설정 전압과 비교하여 SCR2이 도통되게 구성한다.According to the present invention, the charging unit 5 includes the charging unit 5 and the discharge unit 10. The charging unit 5 is controlled by the SCR 1 through the diodes D 2 and D 3 , and then, in the storage battery B. It is configured to be charged and configured to conduct SCR 2 in comparison with the set voltage of the zener diode ZD 1 in the comparator CP 1 .
그리고 방전부(10)는 절환스위치(SW)를 통하여 부하(2) 및 축전지(B)가 연결되게 구성시키고 다이오드(D7)(D9) 및 제너다이오드(ZD2)를 통하여 발광다이오드(LED)가 콜렉터측에 연결된 트랜지스터(Q1)가 제어되게 구성시킨 것이다.The discharge unit 10 is configured such that the load 2 and the storage battery B are connected to each other through the switching switch SW, and the light emitting diodes LED are provided through the diodes D 7 and D 9 and the zener diode ZD 2 . ) Is configured such that the transistor Q 1 connected to the collector side is controlled.
이와같이 구성된 본 고안에서 충전시 충전 어댑터(1)로 연결하면 충전 전압이 충전부(5)의 다이오드(D2)를 통하여 저항(R2)에서 다이오드(D3)로 인가되어 SCR1의 게이트측에 인가되므로 SCR1이 도통하여 충전어댑터(1)의 전원이 SCR1를 통하여 다이오드(D1)를 거쳐 축전지(B)에 충전시키게 되며 다이오드(D2)(D7)를 통한 전원이 발광다이오드(LED)에 공급되는 동시에 제너다이오드(ZD2)를 통하여 트랜지스터(Q1)를 도통시켜 발광다이오드(LED)가 점등되어 충전표시를 한다.In the present invention configured as described above, when connected to the charging adapter 1 during charging, the charging voltage is applied from the resistor R 2 to the diode D 3 through the diode D 2 of the charging unit 5 to the gate side of the SCR 1 . Since the SCR 1 is turned on, the power of the charging adapter 1 is charged to the storage battery B through the diode D 1 through the SCR 1, and the power through the diode D 2 and D 7 is supplied to the light emitting diode ( At the same time, the light emitting diode (LED) is turned on to charge the transistor Q 1 through the zener diode (ZD 2 ).
또한 다이오드(D2)와 저항(R4)을 통하여 제너다이오드(ZD2)로 일정한 전압이 비교기(CP1)에 타측단자(-)에 인가되고 축전지(B)의 충전 전압이 상승되면 다이오드(D1)의 애노우드측 전압이 비교기(CP1)의 일측단자(+)에 인가되므로 충전이 완료된 후 일측단자(+)의 전압이 상승되어 비교기 CP1는 충전 완료시 「H 레벨」신호가 출력되어 SCR2를 도통시키게 된다.In addition, the diode (D 2) with a constant voltage by a Zener diode (ZD 2) via the resistor (R 4) a comparator the other end to the (CP 1) (-) when applied to increase the charging voltage of the battery (B) diode ( Since the voltage on the anode side of D 1 ) is applied to one terminal (+) of the comparator (CP 1 ), after the charging is completed, the voltage of one terminal (+) is increased, and the comparator CP 1 receives the “H level” signal when the charging is completed. Is output to make SCR 2 conduct.
여기서 콘덴서(C2)는 순간적인 전압에 의하여 비교기(CP1)의 출력이 변하는 것을 방지한다.Here, the capacitor C 2 prevents the output of the comparator CP 1 from being changed by the instantaneous voltage.
따라서 다이오드(D2)를 통하여 모두 SCR2로 흐르게 되므로 SCR1이 차단 상태가 되고 발광다이오드(LED)도 소동되어 충전이 완료되었음을 표시하는 동시에 저항치가 큰 저항(R1)을 통하여 미소한 전류만 축전지(B)에 공급되므로써 과충전을 방지할 수가 있는 것이다.Therefore, all of them flow through the diode D 2 to SCR 2 , so that the SCR 1 is blocked and the light-emitting diode (LED) is turned off to indicate that charging is completed. At the same time, only a small current through the large resistance R 1 is obtained. By being supplied to the storage battery B, overcharge can be prevented.
그리고 스위치(SW2)를 접속시켜 부항(2)를 구도시키면 축전지(B)는 방전부(10)를 통하여 방전을 행하는 것으로 방전 전류가 저항(R10)과 다이오드(D7)를 통하여 제너다이오드(ZD2)에서 검지하고 트랜지스터(Q1)가 도통되므로 발광다이오드(LED)가 점등하여 정상적인 방전 중임을 나타내게 되고 축전지(B)의 충전된 전압이 거의 방전되게 되면 트랜지스터(Q1)가 차단되어 발광다이오드(LED)가 소등되므로써 과방전 상태가 되기전에 충전 시기를 사용자에게 알려줄 수가 있는 것이다.When the switch SW 2 is connected to form the cupping unit 2, the storage battery B discharges through the discharge unit 10, and the discharge current passes through the zener diode through the resistor R 10 and the diode D 7 . Detected at (ZD 2 ) and the transistor Q 1 is turned on, the light emitting diode (LED) is turned on to indicate that the normal discharge, and when the charged voltage of the battery (B) is almost discharged, the transistor (Q 1 ) is cut off The light emitting diode (LED) is turned off so that the user can be informed of the charging time before the over-discharge state.
이상에서와 같이 본 고안은 충전시 충전부의 비교기(CP1)에 의하여 과충전 시기를 인식할 수 있게 하며 방전시 방전부(10)에서 제너다이오드의 설정 전압에 의하여 스위칭트랜지스터(Q1)가 제어되게 함으로써 과방전을 방지하는 동시에 발광 다이오드를 소등시켜 충전 시기를 인식시켜줄 수가 있는 것으로 축전지의 수명을 연장시킬 수 있는 효과가 있는 것이다.As described above, the present invention makes it possible to recognize the overcharge time by the comparator CP 1 of the charging unit during charging and to control the switching transistor Q 1 by the set voltage of the zener diode in the discharge unit 10 during discharge. This prevents over-discharge and at the same time turns off the light-emitting diode to recognize the charging time, which has the effect of extending the life of the battery.
