A removable battery component carrier (30,60) for accommodating a battery submodule (40,64) and configured to be mechanically and electrically connected to other removable battery component carriers (30,60) and/or to a carrier frame is provided. The removable battery component carrier (30,60) comprises a bottom plate (32,62), a pair of side walls (31) extending upward from the bottom plate (32,62) along two longitudinal edges of the bottom plate (32,62), a pair of end plates (33) extending upwards from the bottom plate (32,62) along two transversal edges of the bottom plate (32,62). The end plates (33) are mechanically coupled to the side walls (31) and/or to the bottom plate (32,62) to fix battery cells (1,1′) together. A cell cover (34,66) extends parallel to the bottom plate (32,62) so that the cell cover, the bottom plate, the side walls, and the end plates form an accommodating space for the battery submodule (40,64).
