Patent number: 11777436Abstract: A method for a safety concept for an AC battery, in which the AC battery includes a central controller, a plurality of battery modules which respectively have a power board with a plurality of switching states, a plurality of contactors, a plurality of current sensors, a fault loop and a high-speed bus and is connected to a traction machine. The central controller has a hardware-programmable processor unit with at least one microprocessor core on which a control program is configured to control the battery modules, the plurality of contactors and the fault loop. A state machine is implemented by the control program. The battery modules are connected, starting from the central controller, via the high-speed bus and the fault loop. If an abort fault occurs, the AC battery is changed to a safe operating state. The safe state is achieved at least by emergency disconnection of the central controller.Type: GrantFiled: November 4, 2021Date of Patent: October 3, 2023Inventors: Harald Schöffler, Sven Lill, Hermann Helmut Dibos, Daniel Simon, Eduard Specht, Christian Korte, Jan Kacetl, Tomas Kacetl

Patent number: 11658595Abstract: A method for actuating contactors in a traction system. The traction system includes an AC battery, an electric motor, at least one peripheral unit, a plurality of voltage and current sensors, a plurality of contactors, which are arranged in electrical connections to the AC battery and to the electric motor and to the at least one peripheral unit, and a controller having a hardware-programmable processor unit on which a control program for actuating the contactors is configured at the start of operation. After the configuration, a fixed semiconductor circuit structure relating to the actuation of the contactors is available to the processor unit. The traction system has multiple modes of operation. A respective mode of operation is predefined by a general vehicle controller. A respective mode of operation has a plurality of states formed by at least one respective target state and at least one intermediate state.Type: GrantFiled: November 4, 2021Date of Patent: May 23, 2023Inventors: Daniel Simon, Hermann Helmut Dibos, Eduard Specht

Patent number: 11632034Abstract: A method for switching control of a multi-level converter. The multi-level converter has a plurality of modules. A total switching state is formed from respective module switching states of the plurality of modules by the switching control. A current state of charge of all energy stores of the multi-level converter is provided continuously to the switching control. The switching control is divided into an offline part and an online part, wherein, in the offline part, a plurality of offline switching tables is calculated by way of optimizers in a continuous sequence and, for calculation of a respective offline switching table of the plurality of offline switching tables, a respective cost function is minimized according to at least one predefined offline optimization criterion for evaluating the total switching state. In the online part, an online switching table is selected from the plurality of offline switching tables in a continuous sequence.Type: GrantFiled: June 30, 2021Date of Patent: April 18, 2023Inventors: Tomas Kacetl, Stefan Götz, Jan Kacetl, Daniel Simon, Malte Jaensch, Eduard Specht, Hermann Helmut Dibos, Axel Weyland

Patent number: 11407319Abstract: An energy store (14a) has at least three energy storage sections (u, v, w) and at least two switching elements. Each energy storage sections (u, v, w) has multiple energy storage modules and each energy storage module has at least one energy storage element that receives and stores energy from an energy source (12). The energy store (14a) is connected to a first coil (50) so that a voltage induced in the first coil (50) is used to charge the energy storage elements. The energy store (14a) is matched to properties of the voltage provided by the first coil (50) by switching the switching elements. As a result, the energy storage modules of an energy storage section (u, v, w) are connected in parallel and/or in series with one another and/or at least one energy storage module of at least one energy storage section (u, v, w) is bypassed.Type: GrantFiled: June 7, 2018Date of Patent: August 9, 2022Assignee: Dr. Ing. h. c.

Patent number: 11299065Abstract: A method for charging an energy store that has at least three energy storage strings each having plural energy storage modules. The energy storage modules have at least one energy storage element that receives and stores energy from an energy source and at least two switching elements. The energy store is connected to an energy source that provides a charging voltage and to an electric machine, and the energy storage modules are supplied with energy by the energy source. A DC voltage source and/or an AC voltage source are used in a selectable manner as energy source and the energy store is matched to properties of the selected energy source by switching the switching elements. Thus, the energy storage modules of a string are connected in parallel and/or in series with one another and/or at least one energy storage module of at least one energy storage string is bypassed.Type: GrantFiled: June 12, 2018Date of Patent: April 12, 2022Inventors: Stefan Goetz, Hermann Helmut Dibos
