Patent number: 11104232Abstract: An energy supply device for a vehicle having an electric drive, comprising a high-voltage battery having two high-voltage connection contacts and at least one battery string, which is arranged between the high-voltage connection contacts, and at least two string contacts between which the at least one battery string is arranged, and a DC/DC converter, the output side of which provides a low voltage for a low-voltage system of the vehicle and the input side of which is electrically conductively connected to the at least one battery string by way of the two string contacts, wherein the energy supply device is embodied to supply electrical energy to the low-voltage system of the vehicle by way of the at least one battery string in the event of a fault. The invention relates furthermore to a vehicle having an above energy supply device and to a corresponding method for supplying energy for a vehicle having an electric drive.Type: GrantFiled: June 26, 2018Date of Patent: August 31, 2021Assignee: Dr. Ing. h.c.

Patent number: 10828994Abstract: A battery system (10) has at least one battery (9) with a plurality of battery elements (1, 2, 24, n), a regulating or control unit (12) and a switching unit (3) with at least one switching element (6). The regulating or control unit (12) is configured to instruct the switching unit (3) to dynamically switch the at least one switching element (6) over time such that battery elements (1, 2, 24, n) from at least one accordingly dynamically changing subset of the plurality of battery elements (1, 2, 24, n) are connected, and a respective voltage level to be provided is provided thereby for the plurality of load consumers. In addition to providing a plurality of voltage levels, the battery elements (1, 2, 24, n) are deliberately loaded.Type: GrantFiled: April 11, 2016Date of Patent: November 10, 2020Assignee: Dr. Ing. h.c. F. Porsche AktiengesellschaftInventors: Stefan Goetz, Ralf Bauer, Harald Schoeffler, Juergen Mittnacht

Patent number: 9937806Abstract: A charging system (2) for a battery (3) has a first electrical terminal (4) for an AC voltage, a second electrical terminal (5) for a DC voltage and a converter (8). The converter (8) is designed to convert the AC voltage of the first terminal (4) into a DC voltage for charging the battery (3), and to convert a magnitude of a DC voltage that is passed from the second terminal (5) to the converter (8) in terms of the magnitude and to forward it to the battery (3). The converter (8) also is designed to convert the DC voltage of the battery (3) into an AC voltage for driving an electric motor (9).Type: GrantFiled: February 22, 2016Date of Patent: April 10, 2018Assignee: Dr. Ing. h.c.F.

Patent number: 7109604Abstract: A device having an energy-generating unit and a distributor unit for distributing electrical energy to electrical loads. The electrical loads are connected to connector part halves of the distributor unit. Connector part halves, arranged at the load ends of the lines, are connected to connector part halves of the loads. The connector part halves which are connected to the lines have line bridges which serve to close or open a line section of a diagnostic circuit. A switching means is actuated by means of a control unit and is arranged between the energy-generating unit and the distributor unit. A signal generator and an evaluation unit are assigned to the diagnostic circuit. The invention also relates to a method for monitoring the diagnostic circuit.Type: GrantFiled: March 12, 2003Date of Patent: September 19, 2006Assignee: DaimlerChrysler AGInventors: Hassan Kablaoui, Juergen Mittnacht
