摘要:
A temperature control method and a battery system create an optimal temperature range for operating a battery. The battery cells of the battery lie in several separate modules that are integrated in a temperature control circuit. Heat is increased stepwise in a heating phase in which only one first module is heated by means of a temperature control medium, the medium being active in the temperature control circuit and being heated by means of a heating element. The heat that is generated during the operation of at least the first module is used to heat at least one further module.

A battery system includes a plurality of battery cells and a temperature-control element that is thermally conductively connected to the battery cells via a temperature-control surface. The temperature-control element has a temperature-control channel in an interior of the temperature-control element. The temperature-control channel is routed on the forward flow side via an inlet and on the return flow side via an outlet from the temperature-control element. A bypass is connected to the temperature-control channel via a dividing node and a merging node with the dividing node being arranged closer to the inlet than the merging node. A motor vehicle includes the battery system.

A motor vehicle seat including a seat portion having a wind deflector provided in a storage compartment thereof, the wind deflector being mounted for movement between a rest position in the storage compartment and an active position out of the storage compartment. The seat portion also has a rotational joint configured to permit rotation of the seat portion between a first orientation in which the seat portion permits a user to assume a seated position, and a second orientation in which the seat portion permits the wind deflector to assume the active position.

A method for initializing or configuring an electrical circuit, is described. The method includes reading data units stored in a memory device, using data contained in a first data unit part of the data units as a specification for use of data contained in a second data unit part of the data units, and carrying out the initialization or the configuration of the electrical circuit in a manner dependent on a content of an initialization control register contained in the electrical circuit. And in that during the initialization of the electrical circuit, the data read from the memory device can be written once or more often to the initialization control register.

A method for producing a wrapped bushing, includes cutting a metal blank to size: introducing holes into the blank, each hole being provided with at least one inwardly projecting protrusion: inserting plugs of plastics material exhibiting sliding characteristics into the holes; and shaping the blank to form the bushing. The resultant bushing has a substrate of at least one metal in which the holes are provided and filled with the plastics material. Each hole comprises at least one inwardly projecting protrusion.

The invention relates to a method for centering grinding of workpieces, for example optical lenses by a grinding tool using an actuator for generating an advancing movement between the grinding tool and the workpiece, wherein the actuator and a current regulator for an actuator current which determines an advancing force of the actuator are integrated in a position control loop using a predetermined control cycle. For each control cycle: (i) a desired direction of movement (Rsoll(n)) of the advancing movement and an actual direction of movement (Rist(n)) of the advancing movement are ascertained; then (ii) the ascertained actual and desired directions of movement are compared to one another; and (iii) when the comparison results in a deviation between the actual and desired directions of movement, a predetermined current limit (Isollmax) for the actuator current emitted via the current regulator is decreased in a defined manner.
