본 고안은 차량용 배터리의 과충전을 방지하는 차량용 배터리의 과충전 경보 장치에 관한 것이다.The present invention relates to an overcharge alarm device for a vehicle battery that prevents overcharge of the vehicle battery.
제2도는 일반적인 배터리 충전 회로를 도시하는 도면이다. 제2도에서, (1)은 배터리로서, 정측 단자는 메인휴즈(2) 및 키 스위치(3)를 거쳐서 점화계와 전기 부하(4)에 접속되며, 부측 단자는 어스되어 있다. 또한, (5)는 교류발전기로서, 정측 출력단자는 메인 휴즈(2)를 거쳐서 배터리(1)의 정측 단자에 접속되며, 부측 출력단자는 어스되어 있다.2 is a diagram illustrating a general battery charging circuit. In FIG. 2, (1) is a battery, and the positive terminal is connected to the ignition system and the electric load 4 via the main fuse 2 and the key switch 3, and the negative terminal is earthed. Further, reference numeral 5 denotes an alternator, in which the positive output terminal is connected to the positive terminal of the battery 1 via the main fuse 2, and the negative output terminal is earthed.
다음 동작에 대해서 설명을 한다. 키 스위치(3)가 닫히면 배터리(1)의 전압이 시동 전동기(도시되지 않음)에 인가되어 엔진이 시동한다. 엔진 시동에 의해 교류발전기(5)가 구동되어, 발전 출력을 배터리(1)에 공급함과 동시에 전기부하(4)에도 공급한다.The following operation is explained. When the key switch 3 is closed, the voltage of the battery 1 is applied to a starting motor (not shown) to start the engine. By starting the engine, the alternator 5 is driven to supply the power generation output to the battery 1 and also to the electric load 4.
그러나, 상기 충전 회로에 있어서 교류 발전기(5)에 이상이 발생한 경우, 예를 들어 즉 교류 발전기(5)의 레귤레이터(regulator)가 여자 전류를 제어할 수 없는 경우, 교류 발전기(5)의 출력 전압이 규정 값 이상으로 상승되어, 배터리(1)나 전기 부하(4)에 인가된다. 이 경우 메인휴즈(2)는 통상 전부하에 대응해서 60 내지 80A 용량의 것이 사용되고 있으며, 교류 발전기(5)의 발생 전압이 급격히 상승한 경우에는 배터리(1)에는 는 전류가 유입하여, 메인 휴즈(2)가 녹아 배터리(1)의 과충전이 방지된다.However, when an abnormality occurs in the alternator 5 in the charging circuit, for example, when the regulator of the alternator 5 cannot control the excitation current, the output voltage of the alternator 5 It is raised above this prescribed value and applied to the battery 1 or the electric load 4. In this case, the main fuse 2 usually has a capacity of 60 to 80 A in response to a full load. When the generated voltage of the alternator 5 rises rapidly, a current flows into the battery 1 and the main fuse 2 ) Melts to prevent overcharging of the battery 1.
그러나, 교류 발전기(5) 또는 배터리등이 고온 상태인때, 엔진 회전수가 낮을 때, 다른 전기 부하(4)가 많이 사용되고 있을 때 등의 조건하에서는 배터리(1)로의 유입 전류가 적기 때문에 메인 휴즈(2)가 녹지않게 되어, 배터리(1)는 서서히 과충전되어, 배터리(1)액이 새어나거나 배터리(1)에서 발생하는 가스에 의한 본넷트 등의 부식하거나 전기 부하(4)로 고전압이 인가되므로써 파손되는 문제가 있었다.However, since the inflow current to the battery 1 is small under conditions such as when the alternator 5 or the battery is in a high temperature state, when the engine speed is low, when other electric loads 4 are used a lot, the main fuse ( 2) is not melted, the battery 1 is gradually overcharged and damaged by leakage of the battery 1, corrosion of the bonnet by gas generated from the battery 1, or damage due to the application of a high voltage to the electrical load 4. There was a problem.
본 고안은 상기 문제점을 해결하기 위해 이루어진 것으로, 배터리의 과충전을 방지함과 동시에 과충전 상태를 인지할 수 있는 차량용 배터리의 과충전 방지 장치를 얻는 것을 목적으로 한다.The present invention has been made to solve the above problems, and an object of the present invention is to obtain an overcharge preventing device for a vehicle battery capable of preventing overcharging of a battery and recognizing an overcharge state.
본 고안에 따른 차량용 배터리의 과충전 방지장치는 배터리 근처에 설치한 냄새 센서에 의해 배터리의 과충전을 검지하여, 이 과충전 상태를 표시함과 동시에 배터리로의 충전 회로를 차단하도록 한 것이다.The overcharge preventing device for a vehicle battery according to the present invention detects the overcharge of the battery by an odor sensor installed near the battery, and displays the overcharge state and cuts off the charging circuit to the battery.
본 고안에 있어서 배터리의 충전 회로에 이상이 발생하여, 배터리의 과충전 상태가 진행되면 배터리에서 발생하는 가스량을 냄새 센서가 검출하여, 소정값 이상에서 과충전 상태라고 판단하여, 이것을 표시함과 동시에 충전 회로를 차단하여 배터리로 고전압이 인가되는 것을 방지한다.In the present invention, when an abnormality occurs in the battery charging circuit and the battery is in an overcharged state, the odor sensor detects the amount of gas generated in the battery, determines that the battery is in an overcharged state at a predetermined value or more, and displays the charge circuit. To prevent high voltage from being applied to the battery.
제1도는 본 고안의 일 실시예에 의한 차량용 배터리의 과충전 방지장치의 구성도이다. 제1도에서, (1 내지 5)는 종래의 배터리 충전 회로와 동일하기 때문에, 대응하는 부분에 동일 부호를 붙여서 그 설명을 생략한다. (6)은 냄새 센서로, 배터리(1)의 상부 근처에 설치되어 배터리(1) 충전시에 발생하는 가스량을 검출한다. (7)은 이 냄새 센서(6)로부터 나오는 출력신호에 의거해 배터리(1)의 과충전 상태를 판단하는 검지회로, (8)은 자동차의 차실내에 설치되어 검지회로(7)의 출력에 의해 배터리(1)의 과충전 상태를 표시하는 표시부로서의 모니터 램프, (9)는 검지 회로(7)의 출력에 의해 교류 발전기(5)로 부터의 배터리(1)의 충전회로를 차단하는 차단회로 이다.1 is a block diagram of an overcharge preventing device for a vehicle battery according to an embodiment of the present invention. In Fig. 1, since 1 to 5 are the same as in the conventional battery charging circuit, the same reference numerals are given to corresponding parts, and the description thereof is omitted. Denoted at 6 is an odor sensor installed near the top of the battery 1 to detect the amount of gas generated when the battery 1 is charged. (7) is a detection circuit for judging the overcharge state of the battery (1) based on the output signal from this odor sensor (6), (8) is installed in the vehicle interior of the vehicle by the output of the detection circuit (7) The monitor lamp 9 as a display unit for displaying the overcharge state of the battery 1 is a cutoff circuit that cuts off the charging circuit of the battery 1 from the alternator 5 by the output of the detection circuit 7.
다음 동작에 대해서 설명을 한다. 먼저, 통상의 배터리(1) 충전 동작은 종래와 동일하기 때문에 여기에서는 설명을 생략한다. 다음에 교류 발전기(5)의 레귤레이터가 무제어로 되는등, 배터리(1)로의 충전 회로에 이상이 발생하면, 또한 메인 휴즈(2)가 녹지 않는 경우, 배터리(1)가 과충전으로 되어 가스가 다량으로 발생한다. 그래서, 냄새센서(6)는 이 가스량을 검지하며, 검지회로(7)는 이 냄새센서(6)로부터 나오는 출력신호에 의거해 발생 가스량이 소정값 이상의 경우에는 배터리(1)과 과충전 상태라고 판단하여 모니터 램프(8)를 점등시킴과 동시에 차단회로(9)를 동작시킨다. 이에따라 운전자는 충전회로가 이상이라는 것을 인지할 수 있으며, 또한 전기 부하(4)의 파손을 방지함과 동시에 배터리(1)의 과충전 상태에 의한 배터리(1)의 수명저하나 배터리(1)부근의 금속부분의 부식등을 방지할 수가 있다.The following operation is explained. First, since the normal battery 1 charging operation is the same as the conventional one, the description is omitted here. Next, when an abnormality occurs in the charging circuit to the battery 1, such as when the regulator of the alternator 5 becomes uncontrolled, and the main fuse 2 does not melt, the battery 1 becomes overcharged and a large amount of gas is generated. Occurs as Therefore, the odor sensor 6 detects this gas amount, and the detection circuit 7 judges that it is an overcharged state with the battery 1 when the amount of generated gas is more than a predetermined value based on the output signal from the odor sensor 6. The monitor lamp 8 is turned on to operate the cutoff circuit 9 at the same time. Accordingly, the driver can recognize that the charging circuit is abnormal, and also prevents the electric load 4 from being damaged and at the same time reduces the life of the battery 1 due to the overcharged state of the battery 1 or near the battery 1. Corrosion of metal parts can be prevented.
이상과 같이 본 고안에 의하면 배터리의 과충전 상태를, 배터리에서 발생하는 가스를 검지하는 냄새 센서를 사용해서 검지하여, 이것을 표시함과 동시에 배터리로의 충전 회로를 차단하도록 하였으므로, 배터리의 과충전이 방지되며, 또한 전기 부하의 파손도 방지하는 등의 효과가 있다.As described above, according to the present invention, the overcharge state of the battery is detected by using an odor sensor that detects gas generated from the battery, and this is displayed and the charging circuit to the battery is cut off, thereby preventing overcharging of the battery. In addition, there is an effect such as preventing damage to the electrical load.
