A battery module containing a plurality of battery cells electrically connected to one another in series or in parallel, two contact surfaces () for the purposes of tapping off a module voltage of the battery module () and at least one bolted joint device () for the purposes of fixing a component (), in particular a current-conducting component, of the battery module (), wherein the at least one bolted joint device () is provided with a sensor () for the purposes of determining a preload force applied to the bolted joint device ().

Battery module, method for its operation, and its use

A battery cell having at least one battery cell housing and at least one at least partially flexible and moldable wall, wherein the wall is arranged on the battery cell housing. The wall is at least partially comprised of a biomimetic material. Also a battery module with at least one battery cell according to the invention.

Battery cell with partially flexible and moldable wall

The invention relates to a device for removing water from a battery housing () or a battery separator, comprising a body () having a plurality of capillaries (-) and electrodes () for producing an electric field, and a control device () for controlling the electric field for removing water through means of the capillaries (-), a battery housing, a battery separator, a battery system, a vehicle, a method, a computer program and a computer program product.

Device and method for removing moisture from a battery housing

In order to monitor a functional capability of an accumulator for electrical energy of a battery, at least one position sensor is provided which outputs a position signal which is representative of the position of the accumulator. If the duration of an incorrect position exceeds a minimum duration, an incorrect position signal is output by a monitoring device.

Monitoring device and method for monitoring the functional capability of an accumulator for electrical energy of a battery and discharge device, battery system and motor vehicle

The disclosure relates to a vehicle architecture for controlling and regulating an electric drive of an electric or hybrid vehicle, having a power electronics system which is connected firstly to the electric drive and secondly to a battery or to a battery system. A battery management system is associated with the battery or the battery system. The vehicle architecture comprises a master controller or a controller which is equipped with a master functionality into which functionalities at least of the battery management system and of the power electronics system of the electric drive are exported.

Method for operating a battery system

A battery system comprises at least two modules which include a plurality of battery cells, with each module being associated with a cell voltage detection unit which is connected to a central controller via a common communication bus. Each module additionally includes a module voltage detection unit which is connected to the central controller and is configured to separately detect the voltage of the associated module.

Battery system and method for determining battery module voltages

The invention relates to a traction battery having a first battery cell group and a second battery cell group. A first connection of the first battery cell group is connected to a first battery pole by a charging and disconnecting device, a second connection of the first battery cell group is connected to a first service plug connection, a first connection of the second battery cell group is connected to a second service plug connection, and a second connection of the second battery cell group is connected to a second battery pole by a disconnecting device. The first service plug connection and the second service plug connection can be short-circuited by an external service plug. According to the invention, such a traction battery comprises a first jumper connected between the first battery pole and the first service plug connection, by means of which the first battery pole and the first service plug connection can be short-circuited, and/or a second jumper device connected between the second battery pole and the second service plug connection, by means of which the second battery pole and the second service plug connection can be short-circuited.
