팬터그래프(Pantograph)를 이용하여 충전을 하는 전기차(예를 들어, 전기 버스)에서 팬터그래프로부터 충전 전원을 공급받는 충전부의 동결을 방지하고, 충전부에 존재하는 이물질로 인해 충전이 이루어지지 않는 문제를 방지할 수 있도록 한 팬터그래프 충전용 전기차의 충전부 동결방지장치에 관한 것으로서, 전기차에 설치되며, 외기 온도를 차량 정보로 획득하여 팬터그래프 충전장치로 전송하고 충전을 요청하며, 팬터그래프 충전장치의 제어에 따라 충전을 하는 차량 충전 장치, 차량 정보에 포함된 외기 온도와 전기차의 충전부 동결 방지를 위해 미리 설정된 기준온도를 비교하여 그 대소 여부에 따라 동결 방지 기능을 수행하며, 전기차의 충전을 제어하는 팬터그래프 충전장치를 포함하여, 팬터그래프 충전용 전기차의 충전부 동결방지장치를 구현한다.
The present invention relates to a freezing prevention device for a charging part of an electric vehicle for pantograph charging, which prevents freezing of a charging part receiving charging power from a pantograph in an electric vehicle (e.g., an electric bus) that charges by using the pantograph and prevents charging failure due to foreign substances present in the charging part. The freezing prevention device for a charging part of an electric vehicle for pantograph charging comprises: a vehicle charging device that is installed in an electric vehicle, obtains the outside air temperature as vehicle information, transmits the vehicle information to a pantograph charging device, requests charging, and charges depending on the control of the pantograph charging device; and the pantograph charging device that compares the outside air temperature included in the vehicle information with a preset reference temperature to prevent freezing of a charging part of an electric vehicle, performs a freezing prevention function according to the comparison result, and controls the charging of the electric vehicle.
