본 발명은 상면에 소정영역(R)을 구비하는 판상의 베이스프레임(100); 및 상기 소정영역(R)의 내측 상에 배치되고, 상기 베이스프레임(100)의 상면과 평행하게 취해진 단면을 따라 최외곽 프로파일에 의해서 정의되는 단면풋프린트(F, cross-sectional footprint)의 형상이 서로 다르고 상기 단면풋프린트(F)의 면적이 상기 소정영역(R)의 면적보다 작은 복수 종류의 배터리(200)들을 종류 별로 한 개 이상씩 포함하여 구성되는, 복수 개의 배터리(200)들을 포함하는 배터리팩(10)을 제공한다. 이에 따라 상기 복수 종류 중에서 어느 한 종류에 해당하는 한 개 이상의 배터리(200)들이 상기 소정영역(R)의 내측 상에 배치된 경우보다 상기 복수 개의 배터리(200)들이 소정영역(R)의 내측 상에 배치된 경우에 소정영역(R)의 내측 상의 공간의 에너지밀도가 증가할 수 있다.
The present invention provides a battery pack including a base frame (100) which has a plate shape and a certain region (R) on an upper surface, and a plurality of batteries (200) having shapes of cross-sectional footprints (F) defined by an outermost profile of a cross section placed parallel to the upper surface of the base frame (100). The plurality of batteries (200) may be disposed inside the certain region (R)on the upper surface of the base frame (100). The plurality of batteries (200) may include a plurality of types of batteries (200N and 200S) having the cross-sectional footprints (F) which have different shapes. At least a portion (RCP) of a perimeter of the certain region R may obliquely extend. At least a portion (FCP) of a perimeter of the cross-sectional footprint (F) of a special type battery (200S), which is at least one type among the plurality of types of batteries (200), may obliquely extend along the at least a portion (RCP) of the perimeter of the certain region (R).
