A multi-voltage storage system for an at least partly electrically driven vehicle includes a first storage module and a second storage module having an identical rated voltage for storing electrical energy, wherein on-board consumers are connected to the second storage module at least with priority during a charging process, a heating apparatus for heating the storage modules, a switch unit which is designed to connect the first storage module and the second storage module in series for a charging process and in parallel for driving the vehicle, and a control unit, which is firstly designed to control the switch unit before and/or during a charging process such that the parallel connection of the first storage module and the second storage module is eliminated, and which is secondly designed, after elimination of the parallel connection, to activate the heating apparatus before and/or during the charging process.

A device for calibrating two electric motors mounted on one axle in two-axle motor vehicles includes at least one electronic control unit configured to check whether predefined conditions for a switchover from torque control to rotational speed control are met. If met, the at least one electronic control unit is configured to switch to rotational speed control for a predefined period of time. A torque-dependent characteristic map with correction values is created on the basis of this difference. The target torques are corrected by the correction values during torque control after rotational speed control has been deactivated.

A cover electrically couples multiple storage cells of an electrical energy storage module. The cover has electrically conductive contact sockets which are embedded in an electrically insulating material of the cover and taper inwards on their insides, and into which terminals of the storage cells can be inserted to make electrical contact. Two connections are provided, one of which forms a positive terminal and the other of which forms a negative terminal of the electrically coupled storage cells. Multiple conductors electrically couple the storage cells, in particular for coupling the storage cells in series, in a predefined manner. The conductors are completely accommodated inside the cover, and the cover can be mounted on the storage cells such that it can be detached non-destructively.

A driving assistance method for assisting a power-intensive driving maneuver of a subject vehicle includes predicting the power-intensive driving maneuver of the subject vehicle, and determining whether driving maneuver criteria, which comprise at least one energy criterion and at least one traffic criterion, are satisfied for the predicted power-intensive driving maneuver. Determining if the at least one energy criterion is satisfied includes determining a peak power profile required for a full execution of the predicted power-intensive driving maneuver, determining an available drive power of the subject vehicle, and evaluating whether the available drive power is sufficient for the peak power profile, wherein the at least one energy criterion is satisfied if the available drive power is sufficient for the peak power profile. Determining if the at least one traffic criterion is satisfied includes detecting a traffic situation, which comprises at least one traffic condition and/or a route topology, in the surroundings of the subject vehicle, and evaluating whether the predicted power-intensive driving maneuver can be fully executed in the detected traffic situation, wherein the traffic criterion is satisfied if the predicted driving maneuver can be fully executed in detected traffic situation. The method further includes displaying a result of determining whether the driving maneuver criteria are satisfied for the predicted power-intensive driving maneuver.

A method for assisting a power-intensive driving maneuver of an ego vehicle propelled by an electric motor fed from an energy-storage device includes predicting a power-intensive driving maneuver of the ego vehicle, ascertaining a peak-power profile that is needed for a complete execution of the predicted driving maneuver, and determining an available propulsive power of the ego vehicle. The method further includes ascertaining whether the available propulsive power is sufficient for the peak-power profile and, if the available propulsive power is sufficient for the peak-power profile, indicating a recommendation for execution of the predicted driving maneuver. If the available power is not sufficient for the peak-power profile, the method further includes ascertaining whether the available propulsive power is sufficient for a restricted peak-power profile that is needed for a restricted execution of the predicted driving maneuver, indicating a recommendation for restricted execution of the predicted driving maneuver if the available propulsive power is sufficient for the restricted peak-power profile, and indicating a recommendation for non-execution of the predicted driving maneuver if the available propulsive power is not sufficient for the restricted peak-power profile.

A connecting element for electrically connecting a cable to an electrical device of a motor vehicle includes a housing in which at least two electrical contacts are at least partially accommodated and a passage which extends from a first opening of the housing, through the housing, to a second opening of the housing and through which a coolant can flow. In order to allow an electrical connection which satisfies relatively stringent requirements, the electrical contacts are thermally coupled to the passage for active cooling by the coolant.
