Description
본 발명은 전기차 충전기를 이용하여 복수의 전기차에 순차적으로 충전이 이루어지게 하여 충전설비의 이용에 따른 효율성을 향상한 전기차 충전시스템에 관한 것이다.The present invention relates to an electric vehicle charging system that improves the efficiency of using charging facilities by sequentially charging a plurality of electric vehicles using an electric vehicle charger.
일반적으로 전기차 충전소는 전기차의 배터리를 충전하기 위하여 외부에서 전력을 공급받아야 한다. 이러한 외부의 전력은 대부분 주변 건축물에 이미 설치되어 있거나 근처의 배전설비로부터 전력을 공급받아야 한다. 전기차 충전소는 전력을 공급하는 배전설비의 여유율을 감소시키는 요인으로 작용한다. 그마저도 배전설비의 용량이 충분하지 않다면 전기차 충전소의 사용자가 원하는 만큼의 충전기를 설치할 수 없으며, 주차 면수 중 일정 비율로 전기차 충전기를 설치하도록 의무화한 정부의 환경친화적 자동차의 개발과 보급 촉진에 관한 법률 시행령의 개정 사항을 준수하기 어려운 게 현실이다.Generally, electric vehicle charging stations must receive power from an external source to charge the battery of an electric vehicle. Most of this external power must be already installed in surrounding buildings or supplied from nearby distribution facilities. Electric vehicle charging stations act as a factor in reducing the margin ratio of distribution facilities that supply power. Even so, if the capacity of the distribution facility is not sufficient, users of electric vehicle charging stations cannot install as many chargers as they want, and the government's Act on Promotion of Development and Distribution of Environmentally Friendly Vehicles mandates the installation of electric vehicle chargers at a certain percentage of the number of parking spaces. The reality is that it is difficult to comply with the revisions to the enforcement ordinance.
최근 전기차 충전기로서 급속 충전기가 보급되어 그 용량이 점점 더 커지고 있다. 전기차 충전기의 용량 증가에 따라 커지는 전류값을 감당하기 위하여 전력 케이블의 굵기도 커지게 된다. 대부분 저압으로 전력을 공급받는 전기차 충전기에서는 용량 증가에 따른 큰 전류를 감당하기 위하여, 케이블 굵기는 더욱 커질 수밖에 없고, 이로 인하여 전기차 충전소의 설치를 위하여 요구되는 설치비용의 증가와 더불어 전기차 충전기의 이용을 위하여 주차 면수를 확보하여야 하는 큰 어려움을 겪고 있다.Recently, fast chargers have become popular as electric vehicle chargers, and their capacity is increasing. As the capacity of the electric vehicle charger increases, the thickness of the power cable also increases to handle the increased current value. In electric vehicle chargers, which are mostly supplied with power at low voltage, the cable thickness has to become larger in order to handle the large current resulting from the increase in capacity. This increases the installation cost required for installing an electric vehicle charging station and makes it difficult to use electric vehicle chargers. We are experiencing great difficulties in securing parking space for this purpose.
전기차 운전자는 전기차 충전기를 쉽고 빠르게 이용하기에는 설치된 주차 면수가 제한적이다. 따라서 전기차 충전기의 이용을 위하여 해당하는 주차 면수에 주차하고 전기차 배터리의 충전이 완료되면, 다른 전기차 운전자가 전기차 충전기를 긴급하게 사용할 수 있도록 이동 주차하여야 하는 불편함이 있었다. 또한, 종래 전기차 충전기는 전기차 배터리를 충전할 때 전력을 실시간으로 공급하여 충전함으로써, 값싼 잉여전력인 심야전력을 적극적으로 활용할 수 없는 문제도 있었다.The number of parking spaces installed is limited for electric vehicle drivers to use electric vehicle chargers easily and quickly. Therefore, when parking in the appropriate parking space to use the electric vehicle charger and charging of the electric vehicle battery is completed, there was the inconvenience of having to move and park so that another electric vehicle driver could urgently use the electric vehicle charger. In addition, conventional electric vehicle chargers supply power in real time when charging an electric vehicle battery, so there is a problem in that it cannot actively utilize late-night power, which is cheap surplus power.
종래기술로, 도 1의 기존 전기차 충전기(1)는 배전시설에서 전력을 공급받아 1대 또는 2대의 충전케이블(2)로 최대 2대까지 전기차(4)를 충전할 수 있는 구조로 이루어진 시스템이다. 이러한 전기차 충전기(1)는 주차 면수(3)의 제한으로 이동 주차의 번거로움과 전기차의 종류나 배터리의 용량에 대응할 수 없으며, 심야전력과 같은 값싼 전력을 선택할 수 없는 등의 문제가 있었다.As a prior art, the existing electric vehicle charger (1) in Figure 1 is a system configured to receive power from a distribution facility and charge up to two electric vehicles (4) with one or two charging cables (2). . This electric vehicle charger (1) has problems such as the inconvenience of mobile parking due to limitations in the number of parking spaces (3), the inability to respond to the type or battery capacity of the electric vehicle, and the inability to select cheap power sources such as late-night power.
본 발명은 상기 문제를 해결하기 위하여, 단일의 전기차 충전장치로부터 복수의 전기차의 배터리를 충전할 때 순차적인 충전이 이루어지도록 제어하여 전기차 충전장치의 이용을 더욱 효율적으로 운영하기 위한 것이 목적이다.In order to solve the above problem, the purpose of the present invention is to operate the electric vehicle charging device more efficiently by controlling sequential charging when charging the batteries of a plurality of electric vehicles from a single electric vehicle charging device.

The charging status information can be sent as a notification message in real time.
또한, 본 발명에서, 상기 제어부는 복수의 사용자가 입력하여 설정한 정보로부터 충전 우선순위, 충전방식, 충전시간대, 충전용량, 충전케이블의 허용전류 및 충전하려는 전기차의 현재 배터리 충전상태를 포함하는 정보를 비교 판단하여 전환개폐기를 순차 제어하여 충전전력이 공급되도록 할 수 있다.In addition, in the present invention, the control unit includes information including charging priority, charging method, charging time zone, charging capacity, allowable current of the charging cable, and the current battery charging state of the electric vehicle to be charged from information input and set by a plurality of users. By comparing and judging, the switching switches can be sequentially controlled to ensure that charging power is supplied.

본 발명에 따르면, 전기차 충전기의 운영사업자는 전기차 충전기가 설치된 배전설비와 전기차 충전기 사이에 1조의 전력공급 케이블로 설비용량의 증설 없이 보다 많은 전기차 충전구간을 운영하여 공사비를 절감할 수 있고, 전기차 충전기의 사용자는 주차 면수의 확대로 이동 주차의 불편을 해소할 수 있고, 심야전력으로 배터리를 충전할 수 있어 배터리 충전에 따른 비용을 절감할 수 있으며, 정부는 정책에 따라 잉여전력인 심야전력을 활용할 수 있도록 유도하고, 에너지 절감과 저탄소 정책, 그리고 전기차 충전소의 보급 활성화에 이바지할 수 있는 이점이 있다.According to the present invention, operators of electric vehicle chargers can reduce construction costs by operating more electric vehicle charging sections without increasing facility capacity by using one set of power supply cables between the electric vehicle charger and the distribution facility where the electric vehicle charger is installed. Users can solve the inconvenience of mobile parking by expanding the number of parking spaces, and can reduce the cost of battery charging by charging the battery with late-night power. The government can utilize surplus late-night power according to policy. It has the advantage of contributing to energy conservation, low-carbon policies, and the promotion of electric vehicle charging stations.
