Abstract: A battery module with a cell stack which has a plurality of battery cells arranged next to one another in a stacking direction, the battery cells include a first and a second battery cell which are arranged adjacent to one another in the stacking direction. A cell separating element for electrical and thermal insulation of the first and second battery cells from one another is arranged at least between the first and second battery cells, and the cell separating element rests flat on the first and second battery cell. A frictional connection is present between the cell separating element and at least the first battery cell, which connection counteracts a relative movement of the at least one first battery cell and the cell separating element perpendicular to the stacking direction.

Abstract: A battery arrangement having a housing lower part and a housing cover arranged on the housing lower part, and at least one battery module which is arranged in the battery arrangement and which has at least one battery cell. The at least one battery module has a first side defining an upper side and is arranged in the battery arrangement in such a way that the upper side of the battery module faces toward the housing cover and is at a distance from the housing cover in at least one region of the upper side. Furthermore, between the upper side of the battery module and the housing cover, a heat-conducting compound that completely fills a space between the at least one region of the upper side and the housing cover is arranged.

Abstract: An HV energy storage device for a motor vehicle as well as a method for operating the HV energy storage device.

Abstract: A cell module for electric and hybrid vehicles, in which channels for a heat exchange are integrated into at least one outer wall of the module.

Abstract: A method for introducing at least one extinguishing agent into a battery, in particular into a high-voltage battery for a motor vehicle. The at least one extinguishing agent is introduced into a housing of the battery that is at least partially sealed against the penetration of water, in which a plurality of battery cells are arranged. For this purpose, a through-opening is created in a partial region of a wall of the housing, wherein the partial region is penetrated by means of an end region of an extinguishing device. At least one extinguishing agent is introduced into the housing of the battery through a supply channel of the extinguishing device. In addition, the invention relates to an extinguishing device.
