BATTERY SYSTEM INCLUDING REMOVABLE BATTERY COMPONENT CARRIERS

The present invention refers to a removable battery component carrier (30) for accommodating a battery sub-module (40) comprising a plurality of battery cells (1) and configured to be mechanically and electrically connected to other removable battery component carriers (30) and/or to a carrier frame (10) to form a modular battery system (100), the removable battery component carrier (30) comprising a bottom plate (32), a pair of side walls (31) extending upward from the bottom plate (32) along two opposite longitudinal edges of the bottom plate (32), a pair of end plates (33) perpendicular extending upwards from the bottom plate (32) along two opposite transversal edges of the bottom plate (32), the end plates (33) being mechanically coupled to the pair of side walls (31) and/or to the bottom plate (32) for fixing the plurality of battery cells (1) together, and a cell cover (34) extending parallel to the bottom plate (32) so that the cell cover, the bottom plate, the side walls and the end plates form an accommodating space for the battery sub-module (40). The present invention is further directed to a battery system comprising a carrier frame (10) accommodating a plurality of removable battery component carriers (30), wherein each removable battery component carrier (30) is separately detachable from the carrier frame (10).
