The present invention relates to a heat management device of a battery pack for an electric vehicle and a controlling method thereof. The heat management device comprises: a compressed air supply line which supplies, to a battery pack, compressed dry air (hereinafter referred to as ′compressed air′), filled in an air tank supplying compressed air to a braking system as a driving source; a flow control valve which is installed on the compressed air supply line to control the flow of compressed air supplied to the battery pack; a pressure reducing valve which reduces the compressed air with a predetermined pressure; a cooling unit which cools the compressed air; a heating unit which heats the compressed air; and a control unit which controls the operation of each device based on the temperature of the compressed air and the battery pack. The present invention is able to perform heat management efficiently by receiving compressed air from the air tank for supplying compressed air to the braking system, and by cooling or heating the battery pack.

    전기자동차용 배터리팩의 열관리 장치 및 그의 제어방법에 관한 것으로, 제동 시스템에 구동원으로 압축공기를 공급하는 에어탱크에 충진된 압축된 건공기(이하 '압축공기'라 합니다)를 배터리팩으로 공급하는 압축공기 공급라인, 상기 압축공기 공급라인 상에 설치되어 배터리팩으로 공급되는 압축공기의 유량을 조절하는 유량조절밸브, 상기 압축공기를 미리 설정된 압력으로 감압하는 감압밸브, 상기 압축공기를 냉각하는 냉각부, 상기 압축공기를 가열하는 가열부 및 상기 배터리팩과 압축공기의 온도에 기초해서 각 장치의 구동을 제어하는 제어부를 포함하는 구성을 마련하여, 제동 시스템에 압축공기를 공급하는 에어탱크로부터 압축된 건공기를 공급받아 배터리팩을 냉각 또는 가열해서 효율적으로 열관리를 할 수 있다.
