Description

구난차용 전기자동차 충전시스템{Electric vehicle charging system for rescue vehicles}Electric vehicle charging system for rescue vehicles

본 발명은 구난차용 전기자동차 충전시스템에 관한 것이다.The present invention relates to an electric vehicle charging system for a rescue vehicle.

전기자동차는 내연기관 없이 전기 에너지로 주행한다.Electric vehicles run on electric energy without an internal combustion engine.

이와 같은 전기자동차는 구비된 배터리에 전기 에너지를 화학 에너지로 바꾸어 모아 두었다가 필요한 때에 전기로 재생하여 모터를 구동시켜서 회전력을 얻어 주행한다.Such an electric vehicle converts electric energy into chemical energy in a provided battery, stores it, and then regenerates it as electricity when necessary to drive a motor to obtain rotational force and drive.

한편, 전기자동차는 전기자동차 충전소가 가까운 곳에 없는 장소에서 구비된 배터리에 모아 두었던 화학 에너지를 전기로 재생하여 거의 다 사용해서 더이상 주행할 수 없게 되는 경우를 당하기도 한다.On the other hand, electric vehicles may not be able to drive any more by using almost all of the chemical energy stored in batteries in places where electric vehicle charging stations are not nearby.

따라서 구난차에 전기자동차 충전시스템을 구비시켜 구난차가 현장에 가서 충전이 필요한 전기자동차의 배터리에 긴급충전할 수 있도록 함으로써 배터리가 방전된 전기자동차를 원거리까지 견인하지 않고 현장에서 신속하게 해당 전기자동차의 방전된 배터리에 충전할 수 있음에 따라 전기자동차 이용이 더 편리해지도록 할 필요가 있다.Therefore, by equipping the rescue vehicle with an electric vehicle charging system so that the rescue vehicle can go to the site and charge the battery of the electric vehicle that needs charging, the electric vehicle with the discharged battery cannot be towed to a long distance, and the electric vehicle can be quickly installed on site. As the discharged battery can be charged, it is necessary to make the use of electric vehicles more convenient.

이와 관련된 선행기술문헌 정보 : 등록특허공보 제10-2273703호(공고일자 2021년07월07일) "전기자동차 충전 제어 시스템"Related prior art literature information: Registered Patent Publication No. 10-2273703 (Announcement Date July 07, 2021) "Electric Vehicle Charging Control System"

이와 같은 선행기술문헌에 따른 "전기자동차 충전 제어 시스템"은 전기자동차의 배터리 관리 시스템(Battery Management System: BMS)과 통신 컨트롤러(Electric Vehicle Communication Controller: EVCC)가 하나의 하드웨어로 통합된 충전 제어 장치를 이용하여 전기자동차 충전 효율, 보안성 및 차량 사용자의 편의성을 높이도록 한다.The "electric vehicle charging control system" according to such a prior art document is a charging control device in which a battery management system (BMS) of an electric vehicle and an electric vehicle communication controller (EVCC) are integrated into one hardware. It is used to increase the charging efficiency, security and convenience of vehicle users.

그러나, 등록특허공보 제10-2273703호 "전기자동차 충전 제어 시스템"은 전기자동차의 배터리 관리 시스템과 통신 컨트롤러가 하나의 하드웨어로 통합된 충전 제어 장치를 이용하여 전기자동차 충전 효율, 보안성 및 차량 사용자의 편의성을 높이도록 하는 것으로서, 구난차에 전기자동차 충전시스템을 구비시켜 구난차가 현장에 가서 충전이 필요한 전기자동차의 배터리에 긴급충전할 수 있도록 함으로써 배터리가 방전된 전기자동차를 원거리까지 견인하지 않고 현장에서 신속하게 해당 전기자동차의 방전된 배터리에 충전할 수 있음에 따라 전기자동차 이용이 더 편리해지도록 하지는 못한다.However, Korean Patent Publication No. 10-2273703 “electric vehicle charging control system” uses a charging control device in which the battery management system of the electric vehicle and the communication controller are integrated into one hardware to improve charging efficiency, security and vehicle users. In order to increase the convenience of the rescue vehicle, the rescue vehicle is equipped with an electric vehicle charging system so that the rescue vehicle can go to the site and urgently charge the battery of the electric vehicle that needs charging. It does not make the use of an electric vehicle more convenient as it can quickly charge the discharged battery of the electric vehicle in question.

본 발명은 전술한 과제를 해결하기 위하여 안출한 것으로, 구난차에 전기자동차 충전시스템을 구비시켜 구난차가 현장에 가서 충전이 필요한 전기자동차의 배터리에 긴급충전할 수 있도록 하기 위한 구난차용 전기자동차 충전시스템을 제공하는데 그 목적이 있다.The present invention has been devised to solve the above problems, and the rescue vehicle is equipped with an electric vehicle charging system so that the rescue vehicle can go to the site and urgently charge the battery of the electric vehicle that needs charging.
