Patent number: 11784373Abstract: A method for supporting a battery housing when a battery module is inserted. A support device includes a support for supporting the battery housing. Here, the support has several mutually movable pin elements for setting down the battery housing. A negative shape corresponding to a shape of a base bottom side of a housing base of the battery housing by the pin elements is set on the basis of a selective displacement of the support along a predetermined translational direction of movement in that each pin element is displaced from a respective starting position to a respective end position when it reaches the base bottom side and locked at the respective end position by a locking unit. After the negative shape has been set, the support is displaced by a defined offset distance opposite to the direction of movement.Type: GrantFiled: September 7, 2021Date of Patent: October 10, 2023Assignee: AUDI AGInventors: Michael Frauenhofer, Marc Gormanns, Ruben Heid, Oliver Schieler

Patent number: 11705598Abstract: A method for producing a traction battery of a motor vehicle. A battery housing of the traction battery has a receiving compartment for receiving a cell module. It is thus provided that the receiving compartment is delimited by a bottom and walls adjoining said bottom, A topography of the bottom is recorded by measuring technology, a thermal-conductor amount determined by the topography is applied locally to the bottom, whereupon the cell module is inserted into the receiving compartment.Type: GrantFiled: December 3, 2020Date of Patent: July 18, 2023Assignee: AUDI AGInventors: Tobias Benker, Michael Frauenhofer, Oliver Schieler, Andreas Buer

Patent number: 11631882Abstract: A method for producing a traction battery of a motor vehicle. A battery housing of the traction battery has a receptacle for receiving a cell module. It is provided that support surfaces for supporting the cell module spaced apart from a bottom of the battery housing are formed on walls of the battery housing delimiting the receptacle compartment, and that a distance between the support surfaces and the base is measured, an amount of heat conducting calculated from the distance is applied to the bottom, and then the cell module is inserted into the receptacle compartment supported on the support surfaces.Type: GrantFiled: December 3, 2020Date of Patent: April 18, 2023Assignee: AUDI AGInventors: Tobias Benker, Michael Frauenhofer, Oliver Schieler, Andreas Buer

Patent number: 11532861Abstract: A battery device and a method for producing a battery device for a motor vehicle. In said method, a cooling base element and a battery module are provided, and the battery module is mounted on the cooling base element, forming at least one gap between a battery module region and a cooling base region. A filling device is then coupled to at least one filling opening of at least one filling tube, with the at least one filling tube extending into the at least one gap, and a heat conducting medium is introduced from the filling device through the filling tube into the at least one gap.Type: GrantFiled: July 23, 2020Date of Patent: December 20, 2022Assignee: AUDI AGInventors: Marc Gormanns, Tobias Benker, Michael Frauenhofer, Oliver Schieler, Michael Schüßler

Publication number: 20220269308Abstract: A method for determining a quality status of at least one component which is used during a setting process, in which a battery module is provided, which is place in a receptacle region of a battery housing having a housing base on a heat conducting compound located on the housing base and is pressed in the direction of the housing base so that the heat conducting compound located between the battery module and the housing base is at least partially distributed. The predefinable force (F) and the distance (z) covered by the battery module during the setting process in the first direction over the time (t) during the setting process are acquired as monitoring variables and the quality status is determined.Type: ApplicationFiled: January 3, 2022Publication date: August 25, 2022Applicant: AUDI AGInventors: Michael FRAUENHOFER, Matthias WIMMI

Patent number: 8343410Abstract: A production method for producing molded articles from fiber composites, superparamagnetic particles are selected which become coupled to an external alternating magnetic field. These superparamagnetic particles are added to a resin portion of a strip-shaped starting material further comprising reinforcing fibers. The strip-shaped starting material is then continuously advanced, and, while being advanced, heated by coupling-in an external alternating magnetic field to which the superparamagnetic particles in the resin portion become coupled. Next, the heated starting material is continuously molded into a molded article; and the resin portion in the molded particle is cured.Type: GrantFiled: August 21, 2009Date of Patent: January 1, 2013Assignee: Evonik Degussa GmbHInventors: Lars Herbeck, Thorsten Mahrholz, Tobias Stroehlein, Juergen Mosch, Michael Frauenhofer, Stefan Boehm, Klaus Dilger, Harald Haeger, Christian Baron, Markus Pridoehl
