Abstract: A battery module having a plurality of battery cells (2) which are electrically conductively connected to one another in series and/or in parallel and are arranged adjacent to one another in a longitudinal direction (3) of the battery module (1), so that a cell stack (25) is formed. An end plate unit (4) is arranged adjacent to a terminally arranged battery cell (21), wherein the end plate unit (4) comprises at least two end plates (5) formed separately from one another, which are each mechanically connected to a same side surface (6) of the terminally arranged battery cell (21).

Abstract: A battery pack (1) includes a housing (2) and an array of electrochemical cells (80) disposed in the housing (2). The housing (2) includes a container (3) and a lid (30) that closes an open end of the container (3). The container (3) has a base (4), a sidewall (8) that surrounds the base (4), and a spring plate (110) disposed inside the sidewall (8) between the cells (80) and the sidewall (8). The spring plate (110) is free standing within the container (3) and applies a spring force to the cell array that restrains the cells (80) along an axis normal to the surface of the spring plates (110). The lid (30) includes inwardly-protruding pins (50, 60) that further restrain the cells (80) within the housing (2).

Abstract: A battery pack includes a housing and electrochemical cells disposed in the housing. The housing includes a container and a lid that closes an open end of the container. The container has a base, an outer wall the surrounds the base, and a first and a second inner wall disposed inside the outer wall. The first inner wall extends between, and is fixed to, a first portion and a third portion of the outer wall, and is spaced apart from a second portion and a fourth portion of the outer wall. The second inner wall extends between the first portion and the third portion, and is disposed between the first inner wall and the fourth portion. The second inner wall is movable relative to the outer wall such that spacing of the second inner wall from the first inner wall can be changed.
