The present invention relates to a coolant inlet/outlet diameter ratio determination method of a battery cooling device for an electric vehicle that provides a structure of a cooling block to efficiently cool the battery for the electric vehicle and specifically, determines a diameter ratio of a nipple for equal distribution of a coolant flowing through the cooling block. The method comprises: a step of preparing a plurality of cooling blocks; a step of calculating a diameter of the nipple; a step of calculating a flow ratio deviation; and a step of determining the diameter of the nipple. 본 전기자동차용 배터리를 효율적으로 냉각시키기 위한 냉각 블록의 구조를 제공하며, 특히 냉각 블록을 통해 흐르는 냉각수의 균등 분배를 위한 니플의 직경비를 결정할 수 있는 전기자동차용 배터리 냉각 장치의 냉각수 입출구 직경비 결정 방법에 관한 것이다.
