Disclosed are a refrigerant amount monitoring and charging control system for an electric vehicle and a method thereof. The refrigerant amount monitoring and charging control system for an electric vehicle comprises: a controller; a battery management module electrically connected to the controller; a high-speed charging gun connected to the vehicle when charging the vehicle, and generating a high-speed charging signal during a high-speed charging process and transmitting the high-speed charging signal to the controller; an ambient temperature sensor electrically connected to the controller, and acquiring an ambient temperature, and transmitting the acquired ambient temperature to the controller; and a cooling device including an electronic expansion valve and an evaporator. The present invention is able to control charging power through the monitored results of the current refrigerant amount, and prevent a situation where the cooling process using a refrigerant cannot be conducted because there is insufficient refrigerant.

    전기 차량용 냉매량 모니터링 및 충전 제어 시스템 및 방법이 개시된다. 전기 차량용 냉매량 모니터링 및 충전 제어 시스템은 제어기; 상기 제어기와 전기적으로 연결되는 배터리 관리 모듈; 차량 충전 시 차량에 연결되고, 고속 충전 시 고속 충전 신호를 생성하여 고속 충전 신호를 상기 제어기로 발송하는 고속 충전건; 상기 제어기와 전기적으로 연결되며, 주변 온도를 획득하고, 획득한 주변 온도를 상기 제어기로 발송하는 주변 온도 센서; 및 전자 팽창 밸브와 증발기를 포함하는 냉각 장치를 포함하는 전기 차량용 냉매량 모니터링 및 충전 제어 시스템이 제공된다. 본 발명은 현재 냉매량의 모니터링 결과를 통해 충전 전력을 제어함으로써, 냉매 부족으로 인해 냉매를 통해 냉각시킬 수 없는 상황을 방지한다.
