Consists of
이와같이 구성되는 본 고안의 작용, 효과를 상세히 설명하면 다음과 같다.If described in detail the operation, effects of the subject innovation is configured as follows.
제1도 및 제2도를 참조해서 우선 AC전원이 전원공급부(1)로 입력되면 소정의 전원으로 낮아진 후 DC전원으로 변환되어 디스플레이부(2) 및 제어부(3)로 DC전원이 공급된다.Referring to FIGS. 1 and 2, first, when AC power is input to the power supply 1, the AC power is lowered to a predetermined power, and then converted into DC power, and DC power is supplied to the display unit 2 and the controller 3.
만약, 제어부(3)의 배터리팩 삽입부(BP)에 배터리팩이 없으면 제어부(3)는 동작되지 않고, 디스플레이부(2)는 대기상태를 램프로 표시한다.If there is no battery pack in the battery pack insertion unit BP of the controller 3, the controller 3 is not operated and the display unit 2 displays a standby state by a lamp.
그러나, 제어부(3)의 배터리팩 삽입부(BP)에 배터리팩이 있으면 제어부(3)는 배터리 충전을 시작하고, 이를 디스플레이부(2)에 충전중이라고 램프로 표시한다. 상기 제어부(3)에서 는, 상기 전원공급부(1)에서 공급된 전원이 배터리팩 삽입부(BP)로 공급되어 배터리 충전이 시작되면 배터리팩의 +단자와 T단자를 통해서 릴레이(RY)의 NC단자와 COM단자 및 B-단자로 충전전류가 흐른다. 이때 배터리팩의 -단자와 B-단자 사이의 전압 차이는 OV이므로 충전회로(CC)는 동작되지 않는다. 또한, 충전시 배터리팩의 내부에 있는 더말프로텍터(T1)를 체크 해서 온(0N)상태이면 충전을 계속하고, 오프(OFF)상태이면 충전을 종료시키기 위해 상기 배터리팩의 T단자로 흐르는 충전전류를 차단한다.However, if there is a battery pack in the battery pack insertion unit BP of the controller 3, the controller 3 starts charging the battery and displays the lamp as being on the display unit 2 as being in charge. In the control unit 3, when the power supplied from the power supply unit 1 is supplied to the battery pack inserting unit (BP) to start charging the battery NC of the relay (RY) through the + terminal and the T terminal of the battery pack Charge current flows through the terminal, COM terminal and B- terminal. At this time, since the voltage difference between the-terminal and the B-terminal of the battery pack is OV, the charging circuit CC is not operated. In addition, when charging, the thermal protector T1 inside the battery pack is checked to continue charging if it is on (0N) state, and if it is OFF, charging current flowing to the T terminal of the battery pack to end charging. To block.
더말 프로텍터(T1)은 배터리 팩의 내부에 부착된 온도 스위치로서 배터리-단자와 외부의 T1단자와 연결되어 있고, 배터리 팩이 급속 충전기에 삽입되어 급속 충전되면 배터리의 온도가 상승하는데 배터리가 만충전될 경우 약 40~45℃에 이른다. 이때, 더말 프로텍터(T1)의 정격 온도는 40℃에서 온/오프하는 부품을 사용하여 배터리가 만충전된 경우 온도를 감지하여 충전을 정지시키게 된다.The thermal protector T1 is a temperature switch attached to the inside of the battery pack and is connected to the battery terminal and the external T1 terminal. When the battery pack is inserted into the rapid charger and rapidly charged, the temperature of the battery rises. If it reaches about 40 ~ 45 ℃. At this time, the rated temperature of the thermal protector (T1) is to stop the charging by detecting the temperature when the battery is fully charged using a part on / off at 40 ℃.
이때 배터리팩의 -단자와 B-단자 사이에는 전압차가 생기고, 배터리팩의 -단자와 충전회 로(CC)의 저항(R1)을 통해 흐르는 전류가 콘덴서(C1)를 충전시킨다.At this time, a voltage difference is generated between the negative terminal and the B terminal of the battery pack, and a current flowing through the negative terminal of the battery pack and the resistor R1 of the charging circuit CC charges the capacitor C1.
상기 콘덴서(C1)가 소정의 레벨까지 충전되면 저항(R3)을 통해 트랜지스터(TR1)가 온(ON)상태로 동작되고, 릴레이(RY)의 NO단자와 COM단자가 접속되도록 릴레이(RY)가 동작되어 배터리 충전이 종료됨과 동시에 디스플레이부(2)에서 충전종료를 램프로 표시한다.When the capacitor C1 is charged to a predetermined level, the transistor TR1 is operated in an ON state through the resistor R3, and the relay RY is connected to connect the NO terminal and the COM terminal of the relay RY. The battery is ended and the display unit 2 displays the end of charging as a lamp.
또한, 배터리 충전이 종료된 후 배터리 팩을 빼내지 않고 배터리팩 삽입부(BP)에 그대로 방치하여도 배터리팩의 더말프로텍터(T1)가 온(0N)되지만 이미 릴레이(RY)가 온(ON) 상태로 되어 있으므로 배터리 충전에는 아무런 영향도 주지 못한다.In addition, even when the battery pack is left in the battery pack insertion unit BP without removing the battery pack, the thermal protector T1 of the battery pack is turned on (0N), but the relay RY is already on. As it is, it has no effect on battery charging.
릴레이(RY)의 작용을 구체적으로 설명하면 다음과 같다. 릴레이(RY)는 전원 공급시 온 되어 있는 접점 ON, 오프되어 있는 접점 NC, 무전원시 온 되어 있는 접점 NC, 오프되어 있는 접점 ON으로 되어 있다. 배터리 팩 삽입시 더말 프로텍터(T1)가 온 되어 있을때(미충전시임) 배터리 팩의 +단자를 통해 더말 프로텍터(T1)와 릴레이(RY)의 NC 접점으로 충전전류가 흐른다. 이때, 배터리 팩의 -단자의 전위는 0V이므로 트랜지스터(TR1)가 오프이고 릴레이(RY)도 무전원 상태이다. 그러나, 배터리가 만충전되면 더말 프로텍터(T1)는 배터리 온도 상승에 의해 오프 상태로 된다. 이때, 배터리 팩-단자의 전위가 올라가 트랜지스터(TR1)가 온되어 릴레이(RY)가 동작되어 온 상태로 된다. 이때부터는 배터리의 충전통로가 끊기므로 충전을 멈추며 배터리 팩을 빼기 전에는 이 상태를 유지한다. 시간이 흘러 배터리의 온도가 떨어져 더말 프로텍터(T1)가 다시 온 되어도 릴레이(RY)는 ON으로 유지되어 충전을 시작하지 않게 된다. 즉, 릴레이(RY)는 충전 완료 상태를 유지시키는 역할을 하게 된다.The operation of the relay RY will be described in detail as follows. The relay RY is set to the contact ON that is turned on when the power is supplied, the contact NC that is turned off, the contact NC that is turned off when the power is turned off, and the contact ON that is turned off. When the thermal protector T1 is turned on (not charged) when the battery pack is inserted, a charging current flows to the NC contact of the thermal protector T1 and the relay RY through the + terminal of the battery pack. At this time, since the potential of the negative terminal of the battery pack is 0V, the transistor TR1 is turned off and the relay RY is also in an unpowered state. However, when the battery is fully charged, the thermal protector T1 is turned off by the battery temperature rise. At this time, the potential of the battery pack terminal increases, and the transistor TR1 is turned on to operate the relay RY. At this time, the charging passage of the battery is cut off, so it stops charging and maintains this state until the battery pack is removed. As time goes by and the battery temperature drops and the thermal protector T1 is turned on again, the relay RY remains ON and does not start charging. That is, the relay RY serves to maintain the charging completion state.
배터리충전시 정전되었다가 다시 전원이 들어오는 경우에도 제어부(3)의 충전회로(CC)에는 변화가 없으므로 배터리팩의 빼냄없이 배터리를 계속충전한다.Even when the power is turned off and the power is turned on again, the charging circuit CC of the controller 3 does not change, and thus the battery is continuously charged without removing the battery pack.
그리고, 디스플레이부(2)는 배터리충전시 각각의 상태를 램프로 표시한다.In addition, the display unit 2 displays each state as a lamp during battery charging.
이상 설명한 바와 같이, 본 고안에 의하면 배터리팩을 급속충전기에 삽입함으로써 배터리 충전이 자동으로 개시되고, 또 충전시 정전된 후 다시 전원이 들어와도 급속충전기에 대한 조작없이 배터리를 계속충전할 수 있는 효과가 있다.As described above, according to the present invention, the battery charging is automatically started by inserting the battery pack into the rapid charger, and even when the power is turned on again after a power failure, the battery pack can be continuously charged without the operation of the rapid charger. have.
