Abstract

A cell holder structure for holding a plurality of battery cells includes a holder base part and a holder cover part forming an array of cell-receiving spaces and cell intermediate spaces lying inbetween. The holder base part has one or more base side cell supporting pillars extending axially from a base plane of the holder base part into cell intermediate spaces and has a circumferential side securing wall region abutting in an axially and radially position securing manner against a circumferential surface of battery cells to be accommodated in the cell receiving spaces, and/or the holder cover part has one or more cover side cell-supporting pillars which extend axially from a cover plane of the holder cover part into the cell intermediate spaces and have a circumferential side securing wall region abutting in an axially and radially position securing manner against a circumferential surface of the rechargeable battery cells.
