A battery module comprising at least one battery cell (), wherein the battery module () further comprises a propagation protection element () which is connected in a thermally conductive manner to the battery cell () and which is designed in such a way that, when a specific value for a temperature of the at least one battery cell () is exceeded, an endothermic process which is being executed within the propagation protection element () absorbs heat which is given off by the at least one battery cell ().

Battery module and use of a propagation protection element

The invention concerns a battery module () consisting of a number of battery cells () electrically connected to one another by means of connectors (). The battery module () comprises a number of temperature sensors (). The battery module () comprises at least one intermediate cell () with an integrated temperature sensor system () comprising temperature sensors ().

Battery module

A filling device () for filling battery devices (BV) with battery cells (), in particular lithium-ion battery cells, comprising a retaining device () with a fixing device () for fixing battery cells (), and a filling nozzle suitable for connecting to battery devices (BV) and for filling battery devices (BV) with battery cells, wherein the retaining device comprises a cooling device () that is suitable for cooling the retaining device and the battery cells.

Filling device for filling battery devices with battery cells

The invention relates to a method for the voltage-controlled deactivation of battery cells () within a battery module () or a battery pack () and for the voltage-controlled deactivation of electronic components (-) which are electrically connected to the battery cells and which are supplied with power by the battery cells. If a voltage falls below a threshold in the battery cells (), supply lines () to the electronic components (-) are automatically interrupted and/or battery cells () of the battery modules () are separated from the main current circuit of the battery or of a battery pack ().

Method and device for the voltage-controlled self-deactivation of electronic components or battery cells

The present invention relates to a battery system having a battery which is designed to supply a high-voltage power system and can be connected by at least one of its high-voltage power system terminals via a contactor (), which battery system comprises a control coil (), and closes in one state in which a control current flows through the control coil, and opens in a further state in which no current flows through the control coil. In this context, in order to generate the control current, the control coil can be connected via a supply circuit () to a supply unit () by means of which a predetermined voltage can be made available which is lower than the voltage generated by the battery. In addition, the contactor or the supply circuit comprises an energy accumulator () which can be charged with a predetermined quantity of electrical energy by means of the supply unit which is connected to the control coil and makes available the predetermined voltage, and in the event of the predetermined voltage being lost, said contactor can continue to generate the control current flowing through the control coil for a first time by outputting the charged quantity of energy.
