본 고안은 배터리에 전원이 충전되는 것을 제어하는 충전제어회로에 관한 것으로, 특히 하나의 배터리에만 전원을 충전시킬 경우에는 급속충전하고, 두개이상의 배터리에 전원을 충전시킬 경우에는 완속충전하는 것을 자동으로 제어하는 배터리의 충전제어회로에 관한 것이다.The present invention relates to a charging control circuit that controls the charging of power to a battery, in particular, when charging the power to only one battery, the fast charging, and when charging the power to two or more batteries automatically slow charging It relates to a charge control circuit of a battery to control.

일반적으로 배터리에 전원을 급속충전할 경우에는 전원회로의 전류용량이 매우 커야되며 전원회로에 사용되는 트랜스는 용량이 매우 큰 것을 사용하고, 완전충전을 할 경우에는 급속충전을 할 경우에 비하여정도의 전류용량만 있으면 되므로 종래에는 하나의 배터리에만 급속충전할 수 있는 용량의 트랜스를 사용하여 절환스위치를 절환시키면서 하나의 배터리에만 충전시킬 경우에는 급속충전하고, 두개 이상의 배터리에 충전시킬 경우에는 완속충전하게 하였으나, 이는 충전시킬 베터리의 수에 따라 절환스위치를 절환해야되므로 사용자에게 번거로움을 주는 결함이 있었다.In general, when the battery is rapidly charged, the current capacity of the power circuit must be very large, and the transformer used for the power circuit has a very large capacity. When the battery is fully charged, the battery is rapidly charged. Since only a current capacity is required, conventionally, the battery is rapidly charged when only one battery is charged while switching the switch using a transformer having a capacity that can be rapidly charged to only one battery, and when the battery is charged with more than one battery, it is slow. Although it was to be charged, this has a defect that is troublesome to the user because the switch must be switched according to the number of batteries to be charged.

본 고안은 이와 같은 종래의 결함을 감안하여, 충전시킬 배터리의 수에 따라 자동으로 급속충전 및 완속충전을 절환시키게 안출한 것으로, 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is designed to automatically switch between fast charging and slow charging according to the number of batteries to be charged in view of such a conventional defect, which will be described in detail with reference to the accompanying drawings.

첨부된 도면에 도시한 바와 같이 제어단자(CS)에 마이콤(1)의 출력단자(OUT)가 접속된 충전용 전원회로(2)의 출력단자(V)를 릴레이스위치(RL11)(RL21)의 가동단자에 접속하여 릴레이스위치(RL11)(RL21)의 타측고정단자(b1)(b2)를 저항(R1)(R2) 및 다이오드(D1)(D2)를 통한후 저항(R3)(R4)을 통한 일측고정단자(a1)(a2)와 함께 배터리 접속단자(B1)(B2)에 접속함과 아울러 그 접속점을 배터리검출부(3)(4)를 통해 다이오드(D3)(D4)의 캐소드에 접속하고, 다이오드(D3)(D4)의 애노드는 저항(R5)을 통해 저항(R6) 및 트랜지스터(TR1)의 베이스에 접속하며, 트랜지스터(TR1)의 콜렉터는 저항(R7)(R8)을 통해 저항(R9)(R10) 및 트랜지스터(TR2)(TR3)의 베이스에 접속하여 트랜지스터(TR2)의 콜렉터는 저항(R11) 및 릴레이(RL1)(RL2)를 통해 상기 충전용 전원회로(2)의 출력단자(V)에 접속하고, 트랜지스터(TR3)의 콜렉터는 저항(R12)에 접속함과 아울러 급속충전 및 완속충전완료 검출부(5)(6)를 통해 마이콤(1)의 입력단자(IN1)(IN2)에 접속하여 구성한 것으로, 상기에서 충전용 전원회로(2)는 마이콤(1)의출력단자(OUT)에서 고전위가 출력되어 그의 제어단자(CS)에 인가되면 정상구동되어 그의 출력단자(V)로 충전전원을 출력시키게 하고, 배터리검출부(3)(4)는 배터리 접속단자(B1)(B2)에 배터리를 접속하면 이를 검출하여 고전위를 출력하게 하며, 릴레이스위치(RL11)(RL21)는 릴레이(RL1)(RL2)가 구동될때 가동단자가 일측 고정단자(a1)(a2)에 각기 접속되어 저항(R3)(R4)으로 급속 충전전원이 흐르게 하고, 구동되지 않을때 가동단자가 타측 고정단자(b1)(b2)에 접속되어 저항(R1)(R2) 및 다이오드(D1)(D2)로 완속충전전원이 흐르게 한다.As shown in the accompanying drawings, the output terminal V of the charging power supply circuit 2, in which the output terminal OUT of the microcomputer 1 is connected to the control terminal CS, is connected to the relay switch RL 11 (RL 21 ). ), And the other fixed terminal (b 1 ) (b 2 ) of the relay switch (RL 11 ) (RL 21 ) to the resistor (R 1 ) (R 2 ) and diode (D 1 ) (D 2 ). After connecting through the resistance (R 3 ) (R 4 ) and the one-side fixed terminal (a 1 ) (a 2 ) to the battery connection terminal (B 1 ) (B 2 ) and the connection point of the battery detection unit (3) through 4 connected to the cathode of the diode (D 3) (D 4) and a diode (D 3) (D 4) of the anode has a resistance through the resistor (R 5) (R 6) and a transistor (TR 1) Is connected to the base of the transistor TR 1 and the collector is connected to the bases of the resistors R 9 (R 10 ) and transistors TR 2 (TR 3 ) through resistors R 7 (R 8 ). (TR 2) of the collector resistor (R 11) and a relay (RL 1) the power for the charge through (RL 2) times Connected to the output terminal (V) of (2), the microcomputer (1) the collector of the transistor (TR 3) through a junction box as well as the charge and slow charge completion detecting section (5) (6) rapidly to the resistance (R 12) to the input terminal (iN 1) (iN 2) that is configured to connect to, the charging power supply circuit (2) in the above is the high potential output from the output terminal (OUT) of the microcomputer (1), its control terminal (CS) When applied, it is normally driven to output charging power to its output terminal (V), and the battery detectors (3) and (4) detect the high potential when the battery is connected to the battery connection terminals (B 1 ) and (B 2 ). The relay switch RL 11 (RL 21 ) has a movable terminal connected to one fixed terminal (a 1 ) (a 2 ) when the relay RL 1 (RL 2 ) is driven so that the resistor (R 3 ) The rapid charging power flows to (R 4 ), and when not driven, the movable terminal is connected to the other fixed terminal (b 1 ) (b 2 ) so that the resistor (R 1 ) (R 2 ) and the diode (D 1 ) (D 2 ) as slow Allow charging power to flow.

이와 같이 구성된 본 고안의 작용효과를 상세히 설명하면 다음과 같다.Referring to the effect of the present invention configured in this way in detail as follows.

전원단자(Vcc)에 전원이 인가되고, 배터리접속단자(B1)에만 배터리를 접속하며, 마이콤(1)에 의해 충전용 전원회로(2)의 제어단자(CS)에 고전위가 인가되어 정상 구동되면, 배터리검출부(3)는 배터리접속단자(B1)에 배터리가 접속되었음을 감지하여 고전위를 출력하고, 배터리검출부(4)는 저전위를 출력하므로 전원단자(Vcc)의 전원이 저항(R6,R5) 및 다이오드(D4)를 통해 배터리검출부(4)의 출력단자로 흐르면서 트랜지스터(TR1)의 베이스에 저전위가 인가되어 온되고, 이에따라 전원단자(Vcc)의 전원이 트랜지스터(TR1)를 통하고, 저항(R7)(R8)을 통해 트랜지스터(TR2)(TR3)의 베이스에 인가되어 그가 온되므로 충전용전원회로(2)의 출력전원이 릴레이(RL1)(RL2) 및 저항(R11), 트랜지스터(TR2)를 통해 접지로 흐르게되어 릴레이(RL1)(RL2)가 구동된다.Power is supplied to the power supply terminal (Vcc) is, the battery connection terminal (B 1) only and connected to the battery, is applied to the high potential to the control terminal (CS) of the charging power supply circuit (2) by the microprocessor (1) Normal When driven, the battery detector 3 detects that the battery is connected to the battery connection terminal B 1 and outputs a high potential, and the battery detector 4 outputs a low potential so that the power supply of the power terminal Vcc is a resistor ( Low potential is applied to the base of the transistor TR 1 while flowing to the output terminal of the battery detector 4 through R 6 and R 5 and the diode D 4 , and accordingly, the power supply of the power supply terminal Vcc is turned on. The output power of the charging power supply circuit 2 is applied to the base of the transistors TR 2 and TR 3 through (TR 1 ) and through the resistors R 7 and R 8 so that they are turned on. 1 ) RL 2 , resistor R 11 , and transistor TR 2 flow to ground to drive relay RL 1 RL 2 .

따라서, 릴레이스위치(RL11)(RL21)의 가동단자가 일측 고정단자(a1)(a2)에 단락되므로 충전용 전원회로(2)의 출력전원이 릴레이스위치(RL11) 및 저항(R3)을 통해 배터리접속단자(B1)에 접속된 배터리에 급속충전된다.Therefore, since the movable terminal of the relay switch RL 11 (RL 21 ) is short-circuited to one fixed terminal a 1 (a 2 ), the output power of the charging power supply circuit 2 is relay switch RL 11 and the resistor ( R 3 ) is rapidly charged to the battery connected to the battery connection terminal (B 1 ).

그리고, 상기에서 배터리접속단자(B2)에만 배터리를 접속했을 경우에도 상기와 같이 동작하여 충전용 전원회로(2)의 출력전원이 릴레이스위치(RL21) 및 저항(R4)을 통해 배터리에 급속 충전을 하게 된다.When the battery is connected only to the battery connection terminal B 2 , the output power of the charging power circuit 2 is connected to the battery through the relay switch RL 21 and the resistor R 4 . You will be charging fast.

한편, 배터리접속단자(B1)(B2)에 모두 배터리를 접속하여 전원을 충전할 경우에는 배터리검출부(3)(4)의 출력단자에 모두 고전위가 출력되어 상기와는 반대로 트랜지스터(TR1)가 오프되고, 트랜지스터(TR2)(TR3)가 모두 오프되므로 릴레이(RL1)(RL2)가 모두 구동되지 못하며 릴레이스위치(RL11)(RL21)의 가동단자가 타측고정단자(b1)(b2)에 각기 단락되고, 충전용 전원회로(2)의 출력전원이 릴레이스위치(RL11)(RL21) 및 저항(R1)(R2), 다이오드(D1)(D2)를 통해 배터리에 완속충전을 하게 된다.On the other hand, when all the batteries are connected to the battery connection terminals B 1 and B 2 to charge the power, high potentials are output to the output terminals of the battery detectors 3 and 4, respectively. 1 ) is turned off, and the transistors TR 2 and TR 3 are all turned off, so that the relays RL 1 and RL 2 are not driven and the movable terminals of the relay switches RL 11 and RL 21 are fixed to the other side. (b 1 ) and (b 2 ) respectively short-circuited and the output power of the charging power supply circuit 2 is relay switch RL 11 (RL 21 ), resistor R 1 (R 2 ), diode (D 1 ) Through (D 2 ) is a slow charging of the battery.

그리고, 상기와 같이하여 배터리에 급속충전 또는 완속충전을 완료하면 급속충전 및 완속충전 완료검출부(5)(6)가 이를 검출하여 마이콤(1)의 입력단자(IN1)(IN2)에 입력시키므로 마이콤(1)은 충전용 전원회로(2)가 동작되지 않게 제어한다.Then, when the fast charge or slow charge is completed in the battery as described above, the fast charge and slow charge complete detection unit (5) (6) detects this and inputs to the input terminal (IN 1 ) (IN 2 ) of the microcomputer (1). Therefore, the microcomputer 1 controls the charging power supply circuit 2 not to operate.

이상에서 설명한 바와 같이 본 고안은 충전시킬 배터리의 수에 따라 자동으로 급속충전 또는 완속충전시키므로 사용자가 보다 편리하게 사용할 수 있는 효과가 있다.As described above, the present invention automatically charges or slow charges according to the number of batteries to be charged, so that the user can use it more conveniently.
