Patent number: 11889649Abstract: The present invention relates to an energy storage device, comprising a switchgear cabinet housing in which a plurality of receiving spaces are provided, in which receiving spaces at least one control device and a variable number of electrical storage blocks are accommodated in an exchangeable manner, wherein the storage blocks can be selectively interconnected in series or in parallel and are connected to power connections by means of a current controller. Therefore, it is initially proposed to form the control device which is installed in the switchgear cabinet housing and the associated power electronics components themselves in a reconfigurable or variable manner in order to allow the controller and power electronics to be matched to another mode of operation or another application, without having to exchange the control and power electronics module and provide corresponding wiring for this purpose.Type: GrantFiled: December 15, 2020Date of Patent: January 30, 2024Assignee: Liebherr-Components Biberach GmbHInventors: Sven Welser, Harald Wanner, Daniel Ried, Michael Schuler, Markus Eichler, Dietmar Sigg

Patent number: 11764718Abstract: The present invention relates to an energy storage device, comprising power terminals for connecting to a voltage circuit of power electronics of a drive system, which drive system can be controlled by an external system controller as well as at least one electrical storage block; at least one power converter for connecting the voltage circuit of the power electronics of the drive system to an internal voltage circuit of the storage block; and a control device for controlling the at least one power converter. Said control device has a controller board having output and/or feed-in control means for controlling the power converter for the outputting of current from/feeding of current into the storage block, and/or voltage closed-loop and/or open-loop control means for the closed-loop and/or open-loop control of the output voltage of the energy storage device. According to the invention, said control device has an adaptation board, which is connected to the controller board.Type: GrantFiled: December 15, 2020Date of Patent: September 19, 2023Assignee: Liebherr-Components Biberach GmbHInventors: Christian Engst, Harald Wanner, Sven Welser, Michael Schuler, Josef Gleinser

Patent number: 11027951Abstract: The present invention relates to a lifting device for example in the form of a crane such as a tower crane, with a hoisting gear comprising a hoisting cable which runs off from a drum that can be driven by a hoisting gear drive, and a hoisting gear brake for holding the hoisting cable in a braked position. The invention furthermore relates to a method for starting up the hoisting gear of such a lifting device from the braked position in which the hoisting gear brake holds a hoisting load, wherein a starting torque is built up by a hoisting gear drive against the closed hoisting gear brake, and the hoisting gear brake is released upon or after reaching the starting torque.Type: GrantFiled: August 5, 2019Date of Patent: June 8, 2021Assignee: Liebherr-Components Biberach GmbHInventors: Stefan Fuehrle, Harald Wanner

Patent number: 9578404Abstract: A vehicle loudspeaker system is provided. The system includes a vehicle body having a trunk floor pan, and a trunk floor that covers the trunk floor pan. The trunk floor has an upper surface and an opposite, lower surface. An electro-acoustic transducer is disposed between the lower surface of the trunk floor and the trunk floor pan. The transducer includes a diaphragm that defines a first radiating surface and a second radiating surface that is opposite the first radiating surface. The electro-acoustic transducer also includes an electro-magnetic motor for driving motion of the diaphragm along a motion axis. The transducer being arranged such that motion axis is within 45 degrees of parallel with the trunk floor. The system also includes a duct that is configured and arranged to direct acoustic energy radiated from the first radiating surface to a region above the upper surface of the trunk floor.Type: GrantFiled: April 22, 2015Date of Patent: February 21, 2017Assignee: Bose CorporationInventors: Martin Amandus Weber, Roland Noller, Harald Wanner, Vladimir Malus
