Provided is a battery pack for electric vehicles, which enables overall weight reduction of a pack while increasing cooling efficiency through intensive cooling of a required portion. Based on a structure improvement and material change of a cooling fin means provided in the battery pack in response to the heat generation environment of a battery cell, the battery pack of the present invention comprises: a housing in which the battery cells are loaded; and the cooling fin means connected to the housing and provided for at least cooling of the battery cell electrodes in correspondence with the temperature distribution of the battery cell.

    배터리 셀의 열 발생 환경에 대응하여 배터리 팩에 제공되는 냉각핀 수단의 구조 개선과 재질 변경 등을 기반으로, 필요한 부분의 집중 냉각을 통하여 냉각효율을 높이면서 팩의 전체적인 경량화를 가능하게 한 전기차용 배터리 팩이 제공된다. 상기 본 발명의 배터리 팩은, 배터리 셀들이 적재되는 하우징; 및, 상기 하우징과 연계되되, 상기 배터리 셀의 온도 분포에 대응하여 적어도 배터리 셀 전극들의 집중 냉각을 가능토록 제공된 냉각핀 수단;을 포함하여 제공될 수 있다.
