The present invention relates to a cabin heater preheating system for an electric vehicle, wherein coolant heated by cooling a control and drive unit is supplied to a cabin heater circuit at an early stage of cabin heater driving to reduce heating time of indoor warm air and to reduce consumed electric energy. The cabin heater preheating system for an electric vehicle comprises: a cabin heater circuit generating warm air for heating the inside of the electric vehicle to supply the warm air to the inside; a control and drive cooling circuit cooling a control and drive unit for controlling and driving the electric vehicle; a control device controlling a coolant flow path in accordance with a heating request; and a control unit circulating high-temperature coolant cooling the control and drive unit in the control and drive cooling circuit into the cabin heater circuit when a heater of the cabin heater circuit is initially driven in accordance with control of the control device to reduce warm air generation time and reduce electric energy.

    제어 및 구동부의 냉각으로 가열된 냉각수를 캐빈 히터 가동 초기에 캐빈 히터 서킷에 공급하여 실내 온풍의 가열 시간을 단축하고 소모되는 전기 에너지를 절감할 수 있도록 한 전기자동차용 캐빈 히터 예열시스템에 관한 것으로서, 전기 자동차의 실내 난방을 위해 온풍을 생성하여 실내로 공급하는 캐빈 히터 서킷, 전기 자동차의 제어 및 구동을 위한 제어 및 구동부를 냉각하는 제어 및 구동 쿨링 서킷, 난방 요청에 따라 냉각수 유로를 제어하는 제어장치 및 제어장치의 제어에 따라 캐빈 히터 서킷의 히터 초기 가동 시 제어 및 구동 쿨링 서킷에서 제어 및 구동부를 냉각한 고온의 냉각수를 상기 캐빈 히터 서킷으로 순환시켜 온풍 생성 시간을 단축하고 전기 에너지를 절감하는 냉각수 유로 제어부를 포함하여, 전기자동차용 캐빈 히터 예열시스템을 구현한다.
