A battery system () has at least one battery () with a plurality of battery elements (, n), a regulating or control unit () and a switching unit () with at least one switching element (). The regulating or control unit () is configured to instruct the switching unit () to dynamically switch the at least one switching element () over time such that battery elements (, n) from at least one accordingly dynamically changing subset of the plurality of battery elements (, n) are connected, and a respective voltage level to be provided is provided thereby for the plurality of load consumers. In addition to providing a plurality of voltage levels, the battery elements (, n) are deliberately loaded.

Battery system with battery control

A battery system () has a battery () for providing a first voltage and has at least one tap () that divides the battery () into at least one first battery element () for providing a first partial voltage and at least one second battery element () for providing a second partial voltage. A power changeover switch () is arranged between the at least one first battery element () and the at least one second battery element () and is designed to change over between the at least one first battery element () and the at least one second battery element () at a changeover rate to be specified.

Battery system

A battery system having a battery having at least one first battery element, at least one second battery element and a center tap between the at least one first and the at least one second battery element, a power changeover switch having a plurality of switching elements for changing over between the at least one first battery element and the at least one second battery element, and at least one pair of output terminals that is electrically connected to the battery, wherein the center tap has a first capacitive store arranged on it that has a store voltage that appears over an appropriate period in accordance with a first and/or second battery element voltage provided by the first and/or second battery element, wherein during the period in which the store voltage appears, a store current decreases from a maximum value to a value of zero.

Battery system for motor vehicle with loss-free switching and automatic charge equalization

A pouch-cell battery arrangement has a shrink sleeve covering (), that surrounds the pouch () at least in places in an interlocking manner.

Pouch-cell battery arrangement and corresponding production method and use

A vehicle having an electric drive device and an energy storage device which is arranged in a housing is disclosed. The energy storage device is formed from a plurality of cells. The housing includes a plurality of partitioning devices, with the result that at least one partitioning device is positioned between two cells. The housing of the energy storage device is connected both to a cooling air intake duct, having an inlet opening, and to a cooling air outflow duct, having an outlet opening. At least one partitioning device is configured in such a way that a plurality of cooling ducts are formed between the cells, and cooling air can flow through the cooling ducts in order to cool the energy storage device.

Vehicle having an electric drive device

A drive arrangement for an electric vehicle has an axle drive device of a portal design with two electric machines for driving the wheels of an axle of the electric vehicle, and at least one electric energy store that can be discharged when an electric machine is operated as a motor and/or can be charged when an electric machine is operated as a generator. The drive arranged is characterized in that the two electric machines () of the axle drive device () are combined with a respectively assigned transmission () in an electric axle to drive the individually suspended wheels () of the axle by means of, in each case, one articulated shaft flange () via a respective articulated shaft. Frequency converters assigned respectively to the two electric machines are combined in a converter unit.

Drive arrangement for an electric vehicle

A battery system with at least one cell having an adjacent temperature-equalizing structure that is provided alternately with the cells and is designed for a medium that carries heat and/or cold to pass through. The cells are individual cells (), and the temperature-equalizing structures are conventional corrugated board () having two cover layers and at least one corrugation arranged between them for the air to pass through.

The invention relates to a motorized watercraft with a control device () and with a drive unit () having a water propeller that is driven by an electric motor (). The electric motor (), an operating unit (), a motor controller (), a battery controller () and a battery () are placed in a vehicle hull, and the water propeller is mounted in a flow channel in the vehicle hull. In order to connect the controlling components and the components to be controlled by means of a system architecture, a system bus and of a man-machine interface, the invention provides that the operating unit (), the motor controller (), and the battery controller () are data-connected by means of a communications device controlled by the control device (). This enables an, in particular, fail-safe transmission of data, a constant monitoring of the system components, and when required, an emergency shut-down.

Motorized watercraft with a control device

In a method for determining road clearance of a vehicle, the vehicle is moved relative to a measurement configuration with a reference surface. One or more magnets, which are disposed on the vehicle and assigned preferably each to a defined measurement point on the vehicle, is detected by at least one device for magnetic field measurement. With the help of at least one device for separation measurement, the separation between the measurement configuration and the bottom side of the vehicle is determined. In this way, a rapid, reliable, repeatable and flexibly usable method for the determination of the road clearance of a vehicle is provided. A corresponding device is provided for implementing the method.
