전기자동차 충전시스템{Electric vehicle charging system}Electric vehicle charging system {Electric vehicle charging system}

본 발명은 전기자동차 충전시스템에 관한 것으로서, 더욱 상세하게는 전기자동차의 충전을 위해 대기하거나, 충전 완료후에도 전기자동차를 이동 주차할 필요가 없어 충전 대기 및 이동 주차 등에 대한 차주의 불편함을 해소할 수 있는 전기자동차 충전시스템에 관한 것이다.The present invention relates to an electric vehicle charging system, and more particularly, eliminates the inconvenience of the owner of waiting for charging and moving parking because there is no need to wait for charging of the electric vehicle or to move and park the electric vehicle even after charging is completed. It is about an electric vehicle charging system that can be.

최근, 탄소과다 배출로 지구온난화현상이 지속화되면서 이상기후 현상이 발생하고 있다. 따라서, 탄소 배출을 줄이기 위해 전기자동차와 하이브리드자동차의 관심과 개발이 지속적으로 이루어지고 있다.Recently, as global warming continues due to excessive carbon emission, abnormal climate phenomena are occurring. Therefore, in order to reduce carbon emissions, interest and development of electric vehicles and hybrid vehicles are continuously being made.

일반적으로 전기자동차 또는 EV(electric vehicle)는 석유 연료와 엔진을 사용하지 않고, 배터리와 모터를 사용하는 자동차를 말한다.In general, an electric vehicle or EV (electric vehicle) refers to a vehicle that uses a battery and a motor without using petroleum fuel and an engine.

이러한 전기자동차는 주차된 상태에서 일반적인 충전시스템에 의해 내부에 장착된 배터리가 충전됨에 따라 배터리에 충전된 전기에너지를 이용하여 운행할 수 있다. As the battery installed inside is charged by a general charging system in a parked state, the electric vehicle can be operated using electric energy charged in the battery.

종래의 전기자동차 충전시스템은 대형 쇼핑센터나 아파트 주차장에 마련된다. 따라서, 전기자동차는 주차장에 주차된 상태에로 충전시스템의 충전케이블을 배터리에 연결하여 배터리를 충전시킨다.Conventional electric vehicle charging systems are provided in large shopping centers or apartment parking lots. Therefore, the electric vehicle charges the battery by connecting the charging cable of the charging system to the battery while parked in the parking lot.

그러나, 종래의 전기자동차 충전시스템은 전기자동차의 배터리를 충전하고자 하는 경우, 먼저 충전을 하고 있는 전기자동차의 충전이 완료되는 동안 후순위의 전기자동차가 대기하여야 하고, 완속으로 충전하는 경우에 더 많은 시간을 대기하여야 하는 불편함이 있다. 또한, 충전이 완료된 이후에는 후속차량의 충전을 위해 이동 주차해야하는 불편함이 있다.However, in the conventional electric vehicle charging system, when attempting to charge the battery of an electric vehicle, a subordinated electric vehicle must wait while the charging of the first electric vehicle is completed, and more time is required when charging at slow speed. There is the inconvenience of having to wait. In addition, after the charging is completed, there is an inconvenience in that the vehicle must be moved and parked in order to charge a subsequent vehicle.

따라서, 이를 해소하기 위해서는 대기하는 전기자동차의 수량에 상당하는 충전기들을 구비하여야 할 뿐만 아니라 충전기들이 설치되는 설치장소도 확보하여야 하므로, 이에 따른 비용이 과다하게 소요되는 문제점이 있다.Therefore, in order to solve this problem, not only should chargers corresponding to the number of waiting electric vehicles be provided, but also an installation place where the chargers are installed should be secured, resulting in excessive costs.
