Housing for a lithium-ion accumulator, a lithium-ion accumulator as well as a car with a lithium-ion accumulator

摘要

A housing for a lithium ion accumulator with a lithium ion accumulator cell stack (11) of at least two prismatic lithium ion accumulator cells (12), characterized in that the housing (10) has a plate of rectangular base (13), a rectangular cover plate (14) parallel to the plane of the base plate (13), two rectangular pressure plates (15), which are arranged between the base plate (13) and the plate of cover (14) and two opposite side surfaces (16) of the housing (10), as well as means for connecting the base plate (13) and the cover plate (14), by which the base plate ( 13) and the cover plate (14) have along the edges (20) pointing towards the clamping pressure plates (15), respectively, a projection (21), which forms an inclined plane (22), leading in the direction of an interior space (19) of the housing (10) towards the base plate (13) or the cover plate (14), because on the sides (23) of the pressure plates (15), which point towards the base plate (13) or towards the cover plate (14), are configured correspondingly to the inclined planes (22) of the base plate (13) and cover plate (14), so that the inclined planes (22) of the base plate (13) and of the cover plate (14) rest on the inclined planes (24 ) of the clamping pressure plates (15), and by which the means for connecting the base plate (13) and the cover plate (14) are screws (17), which are guided through through holes (18), which are arranged in the area of the projections (21) on the base plate (13) and on the cover plate (14), as well as being guided through through holes (18) with an elongated drill-shaped cross section in the clamping pressure plates (15).
