Description
본 발명은 차량의 배터리 제어장치에 관한 것으로, 특히 발전기의 발전 불량시 배터리가 방전되는 시간을 지연시키고, 발전기의 과발전시 배터리 및 각 부하를 과전류로부터 보호하기 위한 배터리의 방전 및 과충전 방지장치에 관한 것이다.The present invention relates to a battery control device of a vehicle, and in particular, to delay the discharge time of the battery in the event of a power generation failure of the generator, and to prevent the discharge and overcharge of the battery for protecting the battery and each load from the over-current when the generator is over-powered It is about.
일반적으로 차량의 전원장치는 도 1에서와 같이, 차량의 전기장치에 전력을 공급하는 장치로써, 각 부하(14)에 전원을 공급하는 배터리(11)와; 엔진의 크랭크풀리로부터 구동벨트에 의해 구동되어 발전 능력이 엔진 회전수에 의존하는 발전기(12)와; 상기 발전기(12)의 발전전압(A)을 설정된 공급전압(B)으로 유지되도록 제어하는 동시에 상기 배터리(11) 및 각 부하에 전원을 공급하는 전압조정부(13)로 이루어진다.In general, as shown in FIG. 1, a vehicle power supply device is a device for supplying electric power to an electric device of a vehicle, and includes a battery 11 for supplying power to each load 14; A generator 12 driven by a drive belt from a crank pulley of the engine, the power generation capability of which depends on the engine speed; The voltage generator 13 controls the power generation voltage A of the generator 12 to be maintained at the set supply voltage B and supplies power to the battery 11 and each load.
상기 발전기(12)의 역할은 엔진이 작동되고 있을 때 차량의 각 부하(14)가 소비하는 전력을 공급함과 동시에 배터리(11)를 충전시켜서 배터리의 충전상태를 양호한 상태(즉, 엔진 재 시동에 충분한 전기량(시동전압)을 유지하는 것)로 유지하는 것이다. 즉, 차량의 각 부하(14)에서 소비되는 전류가 상기 발전기(12)의 발전량 보다 많을 때에는 배터리(11)로부터 그 부족 분(배터리의 방전 전류)을 공급하여 차량의 각 부하(14)의 작동에 지장이 없도록 하고, 차량의 각 부하(14)에서 소비되는 전류가 상기 발전기(12)의 발전량 보다 작을 때에는 여유 분의 발전량을 배터리(11)에 충전한다.The role of the generator 12 is to supply the power consumed by each load 14 of the vehicle when the engine is running, and to charge the battery 11 at the same time to maintain the state of charge of the battery in a good state (ie, engine restart). Maintaining a sufficient amount of electricity (starting voltage). That is, when the current consumed in each load 14 of the vehicle is greater than the amount of power generated by the generator 12, the shortage (discharge current of the battery) is supplied from the battery 11 to operate the respective loads 14 of the vehicle. There is no disturbance, and when the current consumed in each load 14 of the vehicle is smaller than the power generation amount of the generator 12, the power generation amount of the spare is charged in the battery 11.
발전기(12)가 발전되지 않는 경우, 발전기(12)로부터 각 부하(14)에 전력을 공급하지 못하므로 배터리(11)로부터 각 부하(14)에 전력이 공급되어 배터리(11)가 방전되어 결국 주행불능 상태가 된다.When the generator 12 does not generate power, power cannot be supplied to each load 14 from the generator 12, and thus power is supplied from the battery 11 to each load 14, thereby discharging the battery 11 and eventually. Incapable of driving.
즉, 상기 전압조정부(13)는 발전기(12)의 발전전압(A)이 제1소정전압 이하인 것으로 판단되면, 충전경고등을 점등하여 사용자에게 배터리(11)의 충전상태에 이상이 있음을 알릴 뿐 배터리(11)의 방전시간을 연장시키기 위한 별도의 제어가 없다.That is, when it is determined that the generated voltage A of the generator 12 is less than or equal to the first predetermined voltage, the voltage adjusting unit 13 lights a charging warning light to inform the user that there is an error in the state of charge of the battery 11. There is no separate control for extending the discharge time of the battery 11.
또한, 발전기(12)가 과발전하는 경우, 각 부하(14)에는 과전압이 공급되고,배터리(11)는 과충전되어 배터리가 불량상태가 된다.In addition, when the generator 12 is over-powered, each load 14 is supplied with an overvoltage, and the battery 11 is overcharged and the battery is in a bad state.
즉, 상기 전압조정부(13)는 발전기(12)의 발전전압(A)이 제2소정전압 이상인 것으로 판단되면, 충전경고등을 점등하여 사용자에게 배터리(11)의 충전상태에 이상이 있음을 알릴 뿐 배터리(11)의 과충전에 의한 불량을 방지하지 못한다.That is, when it is determined that the generated voltage A of the generator 12 is greater than or equal to the second predetermined voltage, the voltage adjusting unit 13 lights a charging warning light to inform the user that there is an error in the state of charge of the battery 11. Failure to prevent overcharge of the battery 11 is not prevented.
이와 같이, 종래 차량의 전원장치는 발전기가 발전되지 않는 경우 배터리 방전으로 인해 주행중 주행불능 상태가 되어 안전하게 서비스를 받기가 어려우며, 발전기가 과발전하는 경우 배터리가 과충전되어 배터리가 불량상태가 되고 각 부하에 과전류가 공급되어 각 부하가 소손되는 문제점이 있었다.As such, when the generator is not generated, the power supply of the conventional vehicle becomes incapable of driving while driving due to battery discharge, and it is difficult to receive the service safely.If the generator is over-powered, the battery is overcharged and the battery becomes in a bad state and each load There was a problem that each load is burned out due to an overcurrent supplied thereto.
본 발명의 목적은 종래의 문제점을 해소하기 위한 것으로, 특히 발전기의 발전 불량시 각 부하의 소비전력을 제한하여 배터리가 방전되는 시간을 지연시키며, 발전기의 과발전시 발전기의 출력전압을 낮추어 배터리와 각 부하를 과전류로부터 보호하는 배터리의 방전 및 과충전 방지장치를 제공하는데 있다.An object of the present invention is to solve the conventional problems, in particular, to limit the power consumption of each load in the case of poor power generation of the generator to delay the discharge time of the battery, and to lower the output voltage of the generator when the generator is over-powered and An object of the present invention is to provide a battery discharge and overcharge preventing device that protects each load from overcurrent.

When operating the user display unit 30 at the same time cut off the power supply to the load does not affect the running, and if it is determined that the generator 12 is over-powered by operating the user display unit 30 and at the same time the voltage adjuster 13 It is composed of a battery discharge and overcharge control unit 40 for controlling to lower the power generation voltage (A) of the generator.
본 발명은 배터리(11)가 충전 및 방전시 화학 작용에 의해 열이 발생한다는것을 이용한 것으로, 배터리의 표면온도와 발전기의 발전전압(A)에 의해 발전기의 발전불량과 과발전을 판단한다.In the present invention, the battery 11 generates heat by a chemical action during charging and discharging.
