A motor vehicle traction battery arrangement includes two cooling plates respectively disposed in a horizontal plane and a high-voltage battery module. The lower and upper horizontal walls of which are cooled directly by the cooling plates and which encases a plurality of identical rectangular battery cells in a rigid battery module housing. The battery cells are all configured such that they are plate-like and elongated, are parallel to one another in vertical planes (y,z) and each includes two small-area vertical end walls, two large-area vertical side walls and two medium-area horizontal walls. On its end face, each battery cell includes an anodic connecting element and a cathodic connecting element. At least two similar cell stacks including a same plurality of battery cells are provided, and are stacked such that their battery cell side walls adjoin one another. The battery cell horizontal walls directly adjoin a cooled battery module horizontal wall.

Motor vehicle traction battery arrangement

A battery module for a partially or fully electrically operated vehicle, having a battery housing, which has a main body with at least one open end, and at least one battery cell stack, which has a carrier plate at least at one end. The battery cell stack has been introduced into the main body such that the carrier plate substantially closes off the open end of the main body. On the carrier plate, there is provided an at least sectionally peripheral seal, which projects from the carrier plate and bears at least sectionally against the inner surface of the main body. The seal is of air-permeable form, so that, during the introduction of a fluid of relatively high viscosity into an intermediate space between the battery cell stack and the inner surface of the main body, displaced air can escape from the main body through the seal.

The battery cells each have a cell envelope with a cell vent. The battery module housing has a battery-module housing wall with battery-module housing vents. The battery-module housing vents are respectively assigned a first closure arrangement, which first closure arrangement closes the assigned battery-module housing vent in a first state (Z1) and opens it in a second state (Z2), in order to allow at least partial venting of gas from the battery module housing through the assigned battery-module housing vent in the second state (Z2) of the first closure arrangement. At least two of the cell vents respectively lie opposite an assigned battery-module housing vent, at least in certain regions.

A protective plate is arranged on the outer face of the battery cell package that is supported on the inner face of the battery module housing. A recess is provided on the side of the protective plate facing toward or facing away from the battery cell package, in which recess at least one portion of the signal line is arranged.

A motor vehicle body for a motor vehicle includes a battery compartment, a sill, a crossmember arranged in front of the battery compartment in a direction of travel and orthogonally with respect to the sill, and a longitudinal member arranged in front of the crossmember in the direction of travel. A sheet-metal shell is arranged in front of the crossmember between the longitudinal member and an end side of the crossmember.
