Abstract: A device for the thermal treatment of material comprises a housing having a heatable housing jacket, which surrounds a treatment chamber and forms a rotationally symmetrical treatment surface extending in an axial direction, and a drivable rotor, which is arranged in the treatment chamber and extends coaxially. The rotor comprises a shaft, arranged in a manner distributed over the circumference of which are spreading elements. The device also comprises a condensation space, in which a condenser is formed and into which gaseous material components escaping from the material during the thermal treatment can pass, a condensate outlet for discharging the material components condensed in the condensation space, and a vacuum connection, which is fluidically connected to the condensation space. The vacuum connection is arranged in a region of the housing that lies downstream of the treatment surface, as viewed in the transport direction of the material.

Abstract: A method and a device for determining a battery status of a vehicle battery in a vehicle. In this context, complete discharging (S1) of the vehicle battery by vehicle-internal loads of the vehicle, complete charging (S2) of the vehicle battery, measuring (S3) a capacity and/or an energy content of the vehicle battery during the charging of the vehicle battery, and determining (S4) the battery status by means of the capacity and/or the energy content of the vehicle battery take place. The inventive method and the inventive device are advantageous since no additional hardware, apart from the hardware which is otherwise also necessary in the user mode, and also no specialist personnel are necessary to obtain a regular determination of the battery status of a vehicle battery.

Abstract: A method for determining a maximum available first constant current of a battery over a first prediction period includes determining a maximum available second constant current for a second prediction period. The second prediction period occurs after the first prediction period. The method can further include limiting a first difference between the maximum available first constant current and the maximum available second constant current to one of less than or equal to a prescribed absolute value. The method can further include determining a maximum available first constant power of the battery over the first prediction period.

Abstract: The disclosure relates to a method and an arrangement for diagnosing drivers of contactors, to a battery, and to a motor vehicle having such a battery. According to the method, information relating to switching states of at least three drivers of a contactor is stored, with information relating to respective associated desired values of at least one predefinable parameter, in a computer-readable memory. Actual switching states of at least some of the drivers are detected with associated actual values and are compared with the stored desired values in order to diagnose the drivers. A fault is diagnosed if at least one actual value differs from a desired value.
