As well as electric power, it is possible to use a large amount of power by the auxiliary battery, to prevent the discharge of the main battery of the vehicle, to solve the problem of fluctuation of the amount of generated power from the solar cell, and to store and use the solar cell power and the surplus power of the vehicle. Therefore, the present invention relates to a solar cell system for a vehicle capable of increasing energy utilization.

일반적으로 차량에는 전자기기의 발달로 인하여 전기를 사용하는 차량용품이 점차 많아짐과 동시에 그에따른 전력소모량도 많아지는 실정에 있다.Generally, the development of electronic devices in automobiles is accompanied by an increase in the number of automobile products that use electricity and a corresponding increase in power consumption.

종래에는 차량에 주배터리를 장착해 두고 시동을 걸 때 주배터리의 전력을 사용하고 시동이 걸고난 후에는 엔진과 연결된 제네레이터(발전기)가 전력을 발생시켜 주배터리에 전력을 충전하며 각종 전기용품/부품에 전력을 공급하였다. 이 경우 생산되는 전력이 한정되어 있어서 많은 전기용품(공조장치의 팬, 시트공조용 팬, 공기청정기, 이온발생기, 산소발생기, 냉난방기, 냉온장고, 각종 AV기기 등)을 사용하면 차량의 출력이 떨어지고 연료소비가 많아지며, 또한 차량 및 주배터리에 무리를 주는 단점이 있고 주배터리의 방전시에는 스스로 해결하지 못하였다. Conventionally, the main battery is mounted on the vehicle and the main battery power is used to start the engine, and after the engine is started, the generator (generator) connected to the engine generates power to charge the main battery. The component was powered. In this case, since the electric power produced is limited, the use of many electric appliances (fan of air conditioner, fan for seat air conditioner, air purifier, ion generator, oxygen generator, air conditioner, Fuel consumption is increased, and the vehicle and the main battery are disadvantageous, and the main battery can not be solved by itself.

아울러, 시동을 걸지 않은 상태에서는 주배터리의 전력량이 한정되어 있기 때문에 각종 전기용품을 사용할 수 없는 등 많은 문제점이 있었다.In addition, since the amount of electric power of the main battery is limited in a state where no starting is performed, various electric appliances can not be used.

상기한 문제를 해결하기 위해 태양전지를 이용한 기술이 개발되고 있으며, 그 중 미국특허 제6,439,658호는 차량의 썬루프에 태양전지를 설치하고 차량시트에는 환기용 팬을 설치하여 차량이 주차시 태양전지에서 발생된 전력으로 시트의 환기를 하여 시트의 온도를 떨어뜨린다. 시트의 환기팬은 콘트롤러에 의해 조절되며 입력으로는 시트의 온도센서로 시트의 온도가 높아지면 이를 낮추기 위해 팬이 작동된다. 또한 잉여전력이 있을 시에는 차량의 블로워에 전력을 공급해 차량실내의 환기를 하도록 하고 있다.In order to solve the above problem, a technology using a solar cell has been developed. US Pat. No. 6,439,658 discloses a technique in which a solar cell is installed in a sunroof of a vehicle and a ventilation fan is installed in a vehicle seat, And the temperature of the sheet is lowered by ventilation of the sheet. The ventilating fan of the seat is controlled by the controller, and as input, the fan is operated to lower the seat temperature when the seat temperature rises. Also, when surplus electric power is present, electric power is supplied to the blower of the vehicle to ventilate the interior of the vehicle.

그리고, 미국특허 제6,290,593호는 차량의 엔진 정지시에 태양전지에서발생한 전력을 차량환기용 팬에 공급하거나 차량의 배터리를 충전하는데 사용한다. 수동으로 작동되는 스위치에 의해 사용자가 태양전지에서 발생한 전력을 차량환기에 사용하거나 배터리 충전에 사용하도록 하고 있다.In addition, US Patent No. 6,290,593 is used to supply the power generated from the solar cell to the vehicle ventilation fan or to charge the battery of the vehicle when the engine of the vehicle is stopped. The manually operated switch allows the user to use the power generated from the solar cells to ventilate the vehicle or charge the battery.

그러나, 상기 종래의 기술은, 태양전지에서 발생하는 전력량이 작아 작은 용량의 기기만을 사용해야 하기 때문에 기기의 가동율이 떨어지며 이에 따라 실내 환기의 정도가 떨어지는 문제가 있다.However, the conventional technology has a problem in that the operation rate of the device is lowered because the amount of power generated from the solar cell is small and only a device having a small capacity is used, thereby reducing the degree of indoor ventilation.

또한, 차량의 엔진 시동후에는 태양전지의 활용이 어렵고, 태양전지의 발생 전력량이 작아 대용량 기기의 사용이 어려운 문제가 있다. 아울러, 주차시 태양빛이 약할 때는 전력생산량이 적기 때문에 환기시스템 뿐만 아니라 각종 기기의 가동이 미미한 문제도 있었다.In addition, it is difficult to utilize the solar cell after starting the engine of the vehicle, and the amount of generated power of the solar cell is small, making it difficult to use a large-capacity device. In addition, when the sunlight is weak when parking, there is a problem that the operation of the various devices as well as the ventilation system because there is little power production.

상기한 종래의 문제점을 해결하기 위한 본 발명의 목적은 태양전지로부터 발생한 전력을 보조배터리에 저장한 후 사용가능한 전력량 및 입력수단의 정보에 따라 가동가능한 기기를 선정하여 가동시킴으로써 태양전지의 발생전력 뿐만아니라 보조배터리에 의해 대용량의 전력사용이 가능함과 아울러 차량 주배터리의 방전을 방지하고 태양전지로부터의 발생전력량이 변동하는 문제를 해결할 수 있으며 태양 전지의 전력 및 차량의 잉여전력을 저장하여 사용하므로 에너지의 활용도를 높일 수 있는 차량용 태양전지 시스템을 제공하는데 있다.An object of the present invention for solving the above-mentioned conventional problems is to store the power generated from the solar cell in the secondary battery, and then select and operate the movable device according to the amount of power available and the information of the input means to operate the generated power of the solar cell. In addition, it is possible to use a large amount of power by the auxiliary battery, to prevent the discharge of the main battery of the vehicle, to solve the problem of fluctuations in the amount of generated power from the solar cell, and to store and use the solar cell power and the surplus power of the vehicle. To provide a solar cell system for vehicles that can increase the utilization of the.

상기한 목적을 달성하기 위한 본 발명은 차량에 설치됨과 아울러 태양에너지를 전기에너지로 변환하여 전력을 발생시키는 태양전지와, 상기 태양전지와 연결되어 태양전지로부터 발생된 전력을 사용기기에 맞도록 조정하는 전압전환기와, 상기 전압전환기와 연결됨과 아울러 상기 태양전지나 차량 주배터리의 잉여전력을 저장하는 보조배터리와, 상기 보조배터리와 연결되어 사용가능한 전력량 및 입력수단의 정보에 따라 가동시킬 기기들을 선정하고 릴레이모듈을 제어하여 차량에 설치된 기기들을 가동시키는 콘트롤러를 포함하여 이루어지는 것을 특징으로 한다.The present invention for achieving the above object is installed in a vehicle and converts solar energy into electrical energy to generate power and the solar cell connected to the solar cell to adjust the power generated from the solar cell to fit the user equipment A voltage converter connected to the voltage converter, a secondary battery connected to the voltage converter and storing surplus power of the solar battery or the main battery of the vehicle, and devices to be operated according to the amount of power available and input means connected to the auxiliary battery; It characterized in that it comprises a controller for controlling the relay module to operate the devices installed in the vehicle.

이하, 본 발명을 첨부된 도면을 참조하여 설명하면 다음과 같다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to the accompanying drawings.

종래에 있어서와 동일한 구성 및 작용에 대한 반복되는 설명은 생략한다.Repeated description of the same construction and operation as in the prior art will be omitted.

도 1은 본 발명에 따른 차량용 태양전지 시스템을 나타내는 전체구성도이고, 도 2는 본 발명에 따른 차량용 태양전지 시스템의 가동시를 나타내는 블록도이며, 도 3은 본 발명에 따른 차량용 태양전지 시스템에서 전력생산량에 따라 사용가능한 기기들을 나타내는 도면이다.1 is an overall configuration diagram showing a vehicle solar cell system according to the present invention, Figure 2 is a block diagram showing the operation of the vehicle solar cell system according to the present invention, Figure 3 is a vehicle solar cell system according to the present invention A diagram showing devices that can be used according to the amount of power produced.

도시된 바와 같이, 본 발명에 따른 차량용 태양전지 시스템(1)은, 크게 태양전지(10)와, 전압전환기(20)와, 보조배터리(30)와, 콘트롤러(40)로 구성된다.As shown, the vehicle solar cell system 1 according to the present invention is largely composed of a solar cell 10, a voltage converter 20, a secondary battery 30, and a controller 40.

먼저, 상기 태양전지(10)는 차량의 지붕 또는 본네트 등에 설치되며 차량의 외부에서 가해지는 태양에너지를 전기에너지로 변환하여 전력을 발생시키게 된다. 이러한 태양전지(10)는 공지된 것이므로 여기서 상세한 설명은 생략한다.First, the solar cell 10 is installed on a roof or a bonnet of a vehicle and generates power by converting solar energy applied from the outside of the vehicle into electrical energy. Since the solar cell 10 is known, the detailed description thereof will be omitted.

그리고, 상기 전압전환기(DC/DC Converter)(20)는 상기 태양전지(10)와 전기적으로 연결되어 태양전지(10)로부터 발생된 전력을 차량에 설치된 사용기기에 맞도록 조정하는 것이다.In addition, the DC / DC converter 20 is electrically connected to the solar cell 10 to adjust the power generated from the solar cell 10 to fit the user equipment installed in the vehicle.

또한, 상기 보조배터리(30)는 상기 전압전환기(20)와 전기적으로 연결됨과 아울러 상기 태양전지(10)나 차량 주배터리(5)의 잉여전력을 저장(충전)하게 된다. 즉, 엔진의 시동시에는 차량의 주배터리(5) 및 발전기(미도시)에서 발생한 전력이 태양전지 시스템(1)에 공급되어 다양한 기기들을 가동시킬 수 있으며 이때의 잉여전력으로 상기 보조배터리(30)를 충전하게 되며, 엔진의 정지시에는 상기 태양전지(10)에서 발생한 전력으로 보조배터리(30)를 충전하게 된다.In addition, the auxiliary battery 30 is electrically connected to the voltage converter 20 and stores (charges) surplus power of the solar cell 10 or the vehicle main battery 5.
