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.

Method for operating a motor vehicle in a collision situation and motor vehicle

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

HV energy storage device

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.

Cell module for electric and hybrid vehicles

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.

Extinguishing method and extinguishing device for introducing at least one extinguishing agent into a battery

A method is disclosed for checking the absence of voltage on a power electronic component connected to a high-voltage battery and to an electrical machine in a high-voltage network of a motor vehicle, which component has a higher voltage than a low-voltage network of the motor vehicle. The power electronic component includes an intermediate circuit capacitor, a passive discharge resistor, a plug-in terminal for at least one high-voltage load and a fuse which is connected upstream of the plug-in terminal. Following disconnection of the high-voltage battery from the high-voltage network and when the connector of the cable plugged into the plug-in terminal is withdrawn from the plug-in terminal or a target terminal, a feed voltage is applied via the high-voltage contacts of the plug connection and the voltage curve and/or, after a defined charging time interval of the intermediate circuit capacitor, the resistance is measured by means of a measuring instrument, wherein an absence of voltage is determined in the event of a voltage curve lying in an intended range or a resistance lying in an intended range.
