본 고안은 다이리스터와 온도센서를 이용하여 밧데리의 충전을 제어하도록 된 전자회로에 관한 것이다.The present invention relates to an electronic circuit adapted to control charging of a battery using a thyristor and a temperature sensor.

근래에 소개되고 있는 충전밧데리 중에는 급속충전을 할 수 있도록 된 급속충전식 밧데리가 널리 사용되고 있는데, 이러한 밧데리는 비교적 짧은 시간에 충전이 되기 때문에 필요이상의 과충전이 되지 않도록 특히 주의를 기울여야만 하고, 만일 부주의로 과충전 현상이 발생되면 밧데리 자체뿐만 아니라 밧데리가 사용되어지는 장치에 있어서도 무리가 발생되어 고장이나 정상적인 작동을 방해하게 되는 결과가 초래된다.Recently, the fast charging type battery which is able to charge quickly is widely used among the introduced charging batteries. Since such a battery is charged in a relatively short time, it is necessary to pay special attention not to overcharge more than necessary. If overcharging occurs, not only the battery itself but also the device in which the battery is used may cause a malfunction, which may cause a malfunction or interfere with normal operation.

따라서, 과충전 현상이 일어나게 되지 않도록 하는데 많은 노력을 기울이고 있으나 아직 만족할만한 결과를 얻지 못하고 있는 형편이다.Therefore, although much effort has been made to prevent the overcharging phenomenon, it is still difficult to obtain satisfactory results.

본 고안은 이와 같은 상황에 비추어 고안된 것으로서, 급속충전식 밧데리의 충전을 자동 제어하기 위해 다이리스터와 온도 센세의 특징을 이용하여 충전이 완료될 때에 자동적으로 충전전원을 차단시켜 주므로써 필요이상의 과충전을 방지함과 더불어 과충전으로 인한 주변기기의 손상위험을 배제하고자 안출된 것이다.The present invention has been devised in the light of the above situation, and by using the features of the thyristors and the temperature sensor to automatically control the charging of the fast-charged battery, it automatically cuts off the charging power when the charging is completed, thereby preventing overcharging more than necessary. In addition, it is designed to rule out the risk of damage to the peripherals due to overcharging.

이하 본 고안의 구성 및 작용·효과를 예시도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the configuration, operation, and effects of the present invention will be described in detail with reference to the accompanying drawings.

본 고안은 트랜지스터(Q1)(Q2)와 제너다이오드(ZD1)가 구비되어져 있는 정전류 회로(1)에 초단에 충전표시회로(2)가 설치되고, 정전류회로(1)의 출력단에는 온도센서(3)를 구비하고 있는 밧데리 팩(4)과 자동충전회로(5)가 연결되며, 온도센서(3)의 다른쪽 단자와 연결된 다이리스터(6)의 애노우드측은 정전류회로(1)에 있는 트랜지스터(Q2)의 베이스에 연결되는 한편, 그 게이트단은 충전개시 스위치(SW1)를 구비하고 있는 트리거회로(7)와 자동충전회로(5)에 연결되어져 있는 구조로 되어 있다.According to the present invention, a charge display circuit 2 is provided at a first stage in a constant current circuit 1 including transistors Q 1 and Q 2 and a zener diode ZD 1 . The battery pack 4 equipped with the sensor 3 and the automatic charging circuit 5 are connected, and the anode side of the die thruster 6 connected with the other terminal of the temperature sensor 3 is connected to the constant current circuit 1. The gate terminal is connected to the trigger circuit 7 and the automatic charging circuit 5 having the charge start switch SW 1 while being connected to the base of the transistor Q 2 .

미설명부호 8은 급속충전 밧데리를 나타낸다.Reference numeral 8 denotes a fast charge battery.

제1도는 상기와 같은 구조로 되어 있는 본 고안의 계통도로서, 충전을 위해 B+전원이 본 고안 회로에 인가되게 되면, 이 전원은 정전류회로(1)에 의해 전류가 일정치로 조절되어져 그중 일정량이 자동 충전회로(5)에 충전된 다음 밧데리 팩(4)에 설치된 급속충전 밧데리(8)에 인가되게 된다. 이때에는 트리거 회로(7)에 의해서 다이리스터(6)가 턴-온되어 정전류회로(1)가 동작을 하게 된다.1 is a schematic diagram of the present invention having the structure as described above, when B + power is applied to the circuit of the present invention for charging, the power is regulated by a constant current circuit (1) to a constant value of which The automatic charging circuit 5 is charged and then applied to the quick charge battery 8 installed in the battery pack 4. At this time, the thyristor 6 is turned on by the trigger circuit 7 to operate the constant current circuit 1.

이어 충전이 거의 종료될 때쯤이면, 온도 센서(3)의 접점이 밧데리(8)의 발열로 인하여 OFF상태로 되고, 이에 따라 다이리스터(6)가 턴오프되게 되므로 정전류회로(2)의 동작이 중지되어 밧데리 팩(4)으로의 B+전원공급이 차단되게 된다.Subsequently, when charging is almost finished, the contact of the temperature sensor 3 is turned off due to the heat generation of the battery 8, and accordingly the operation of the constant current circuit 2 is turned off because the die Lister 6 is turned off. It will stop and the B + power supply to the battery pack 4 will be cut off.

한편, 충전이 완료되어 급속충전 밧데리(8)를 밧데리 팩(4)로 부터 분리시켜 각기의 용도로 사용하고 난 다음 재충전을 하기 위해 급속충전 밧데리(8)를 밧데리 팩(4)에 접속 설치하게 되면 자동 충전회로(5)에 의해서 다이리스터(6)가 트리거 되어짐에 따라 정전류회로(1)가 동작을 개시하여 재충전이 이루어지게 된다.On the other hand, after the charging is completed, separate the fast charging battery (8) from the battery pack (4) and use it for each purpose, and then connect the quick charging battery (8) to the battery pack (4) for recharging. When the thyristor 6 is triggered by the automatic charging circuit 5, the constant current circuit 1 starts to operate and recharges.

제2도는 상기와 같은 본 고안의 계통적 흐름을 구체화 시킨 회로도인데, 밧데리 팩(4)이 도면의 상태대로 접속되어 회로가 구성된 상태에서 충전용 B+전원이 가해지면 저항(R1)(R4)(R6)과 콘덴서(C1)의 충전시정수에 의한 순간적인 트리거펄스가 다이리스터(6)에 게이트에 공급되어져서 다이리스터(6)가 턴-온되게 되고, 이에 따라 트랜지스터(Q2)의 베이스가 로우레벨로 되어 PNP형인 트랜지스터(Q2)는 턴-온 되어 B+전원이 밧데리(8)측으로 유입되게 된다. 이때 일부전류는 자동충전회로(5)의 콘덴서(C2)에 충전된다.FIG. 2 is a circuit diagram embodying the systematic flow of the present invention as described above. When the battery pack 4 is connected as shown in the drawing and the charging B + power is applied in the circuit configuration, the resistor R 1 (R 4) is shown. (R 6 ) and the instantaneous trigger pulse by the charging time constant of the condenser (C 1 ) are supplied to the gate of the thyristor (6) so that the thyristor (6) is turned on, and thus the transistor (Q) The base of 2 ) becomes low level, and the transistor Q 2 , which is a PNP type, is turned on so that B + power flows into the battery 8 side. At this time, some current is charged in the capacitor C 2 of the automatic charging circuit 5.

한편, 정전류회로(1)의 트랜지스터(Q1)는 저항(R1)(R2)과 제너 다이오드(ZD1)의 값을 적절히 설정해 놓게 됨에 따라 턴온되게 되는데, 이때 제너다이오드(ZD1)의 제너전압(VZD1)은 저항(R1)에 걸리는 전압강하가 VZD1+VEB보다 크게 되도록 정해 놓는다. 이에 따라 트랜지스터(Q1)가 턴온되면 충전표시등(LED1)이 점등되어 충전전류가 흐르고 있음을 표시하게 된다.On the other hand, the transistor Q 1 of the constant current circuit 1 is turned on by properly setting the values of the resistors R 1 (R 2 ) and the zener diode ZD 1 , wherein the zener diode ZD 1 Zener voltage V ZD1 is set such that the voltage drop across resistor R 1 is greater than V ZD1 + V EB . Accordingly, when the transistor Q 1 is turned on, the charging indicator LED 1 is turned on to indicate that the charging current is flowing.

그런데, 이상과 같은 충전시작 싯점에서 만일 다이리스터(6)가 트리거되지 않게 되면 트리거회로(7)의 충전개시 스위치(SW1)를 짧은 시간동안 접촉시켜서 다이리스터(6)를 트리거시켜 주게 되는데, 이렇게 되면 스위치(SW1)가 온으로 되어 콘덴서(C1)의 충전전하가 방전되고, 다시 스위치(SW1)가 오프되면 콘덴서(C1)에 충전전류가 흐르면서 다이리스터(6)의 게이트에 트리거펄스를 공급하게 되어 다이리스터(6)가 턴온되게 된다. 이때 저항(R6)에 걸리는 전압은 매우 작기 때문에 그 전압으로는 다이리스터(6)를 트리거시킬 수가 없으므로 결국 다이리스터(6)의 트리거원은 콘덴서(C1)의 충전전하가 된다.However, if the thyristor 6 is not triggered at the charging start point as described above, the thyristor 6 is triggered by contacting the charging start switch SW 1 of the trigger circuit 7 for a short time. In this case, the switch SW 1 is turned on to discharge the charging charges of the capacitor C 1 , and when the switch SW 1 is turned off again, the charging current flows to the capacitor C 1 to the gate of the thyristor 6. The trigger pulse is supplied so that the thyristor 6 is turned on. At this time, since the voltage applied to the resistor R 6 is very small, the voltage of the die Lister 6 cannot be triggered by the voltage, so that the trigger source of the die Lister 6 becomes the charge charge of the capacitor C 1 .

이어 충전이 완료되어가면 밧데리(8)에서는 비교적 높은 열이 방출되게 되므로 온도센서(3)는 이러한 열을 받아서 그 접점이 개방되게 되고, 그 때문에 다이리스터(6)가 턴오프 됨과 더불어 트랜지스터(Q2)의 베이스측이 접지상태로 부터 오픈되어져 버리므로 트랜지스터(Q2)는 턴-오프되게 되어 충전용 B+전원의 공급이 중단되게 된다.Subsequently, when the charging is completed, relatively high heat is emitted from the battery 8, so that the temperature sensor 3 receives this heat, and the contact thereof is opened, so that the thyristor 6 is turned off and the transistor Q Since the base side of 2 ) is opened from the ground state, the transistor Q 2 is turned off and the supply of the charging B + power is stopped.

이상과 같은 충전 과정에서의 정전류 기능은 다음과 같이 실시된다. 즉 전류량이 정상치를 초과하게 되면 저항(R1)에 걸려지게 되는 전압강하도 커지게 됨에 따라 제너다이도드(ZD1)의 애노드점의 전압이 낮아진다. 그러면 트랜지스터(Q1)의 베이스전압이 낮아지게 되어 PNP형인 트랜지스터(Q1)의 베이스전류가 증가하게 되고, 이 베이스에의 전류증가에 따른 콜렉터 전류증가로 말미암아 상대적으로 저항(R3)과 충전표시등(LED1) 전압이 커지게 되므로 다이오드(D1)를 통해 트랜지스터(Q2)의 베이스에 바이어스 전류가 증가하게 되어 PNP형인 트랜지스터(Q2)의 콜렉터로 흐르는 전류치가 줄어들게 된다. 따라서 밧데리 팩(4)에 공급되는 전류량은 정상치를 유지하게 되는 것이다.The constant current function in the charging process as described above is performed as follows. That is, when the current amount exceeds the normal value, the voltage drop applied to the resistor R 1 also increases, so that the voltage at the anode point of the zener diode ZD 1 decreases. As a result, the base voltage of the transistor Q 1 is lowered, and the base current of the transistor Q 1 , which is a PNP type, is increased, and the collector current increases with the increase of the current to the base, so that the resistance R 3 and the charge are relatively increased. Since the indicator LED 1 increases in voltage, the bias current increases at the base of the transistor Q 2 through the diode D 1 , thereby reducing the current value flowing to the collector of the transistor Q 2 , which is a PNP type. Therefore, the amount of current supplied to the battery pack 4 is to maintain a normal value.

이런 경과를 거쳐 충전이 완료된 후 밧데리 팩(4)으로 부터 급속충전용 밧데리(8)를 분리시켜서 각종 용도에 사용하다가 재충전이 필요하여 충전을 시키고자 할 때의 충전작용은 다음과 같다.After the charging is completed through this process, the fast charging battery (8) is separated from the fast charging battery (8) and used for various purposes, and the recharging is required to charge the battery as follows.

급속충전용 밧데리(8)가 설치된 밧데리 팩(4)을 본 고안 충전장치에다 접속시키면, 급속 충전용 밧데리(8)의 전류전압에 의해서 전류가 순간적으로 콘덴서(C2)를 통하여 다이리스터(6)의 게이트에 인가되게 되고, 이에 따라 다이리스터(6)가 턴-온 되어 자동적으로 전술한 충전 기능이 수행되게 되는데, 이어 충전이 완료되어갈 때 쯤이면 밧데리(8)의 발열로 인하여 온도센서(3)가 오프되므로 B+전원공급이 차단되게 된다.When the battery pack 4 provided with the battery 8 for fast charging is connected to the charging device of the present invention, the current is instantaneously passed through the capacitor C 2 by the current voltage of the battery 8 for fast charging. The thyristor 6 is turned on to automatically perform the above charging function. Then, when the charging is completed, the temperature sensor (6) is generated due to the heat generation of the battery 8. 3) is off, so B + power supply is cut off.

이때 만일 밧데리(8)의 전하가 모두 방전되어 버려 전류전압이 전혀 없을 경우에는 자동 충전회로(5)가 동작을 하지않게 되므로 다이리스터(6)가 턴온되지 않게 되는데, 이런 경우에는 충전개스 스위치(SW1)를 순간적으로 ON시켜서 콘덴서(C1)의 충전전류로 다이리스터(6)를 트리거시킬 수가 있다.At this time, if all the charges of the battery 8 are discharged and there is no current voltage, the automatic charging circuit 5 does not operate, so that the die thruster 6 does not turn on. In this case, the charge gas switch ( SW 1 ) can be turned ON momentarily to trigger the thyristor 6 with the charging current of the capacitor C 1 .

이상에서와 같이 본 고안은 온도센서(3)와 다이리스터(6)의 특성을 이용한 간단한 회로구성으로서 밧데리(8)가 필요치 까지만 충전되도록 하고 그 이상의 과충전을 방지할 수 있게 되므로, 과충전으로 인한 밧데리(8)의 손상이나 주변기기의 손상을 방지할 수 있는 장점을 가지고 있다.As described above, the present invention is a simple circuit configuration using the characteristics of the temperature sensor (3) and the thyristor (6), so that the battery (8) is charged only to the required level and can prevent the overcharging further, the battery due to overcharge (8) has the advantage of preventing damage to the peripheral equipment.
