Publication number: 20210178928Abstract: In a method for controlling the service life of an energy storage module, a state of health (SoH) of the energy storage module is known at different times. In order to improve the control of the service life of an energy storage module, it is proposed that a speed of ageing is determined from a first known state of health of the energy storage module at a first time, and a second state of health of the energy storage module at a second time, wherein an end time of a determined end of service life is calculated from the speed of ageing and from one of the known states of health (SoH), wherein depending on the calculated end time of the determined end of service life a measure for changing the service life of the energy storage module is applied.Type: ApplicationFiled: January 26, 2017Publication date: June 17, 2021Applicant: Siemens AktiengesellschaftInventors: Swen RUPPERT, Eugen HOLL

Patent number: 7633271Abstract: This invention is a system and a method that uses the braking resistor, commonly used and available in electrically or hybrid-electrically propelled vehicles, to limit the precharge current during the startup of a high power ultracapacitor pack energy storage device and/or safely and rapidly discharge an ultracapacitor pack for maintenance work or storage to lengthen the life of the individual ultracapacitor cells and, correspondingly, the whole pack. The use of the braking resistor for precharging an ultracapacitor energy storage pack is an effective and less expensive method compared to other methods such as a separate DC-to-DC converter. This method includes the control logic sequence to activate and deactivate switching devices that perform the connections for the charging and discharging current paths.Type: GrantFiled: November 26, 2008Date of Patent: December 15, 2009Assignee: ISE CorporationInventors: Juergen J.

Patent number: 7462944Abstract: A hybrid driving system for a vehicle including a generator connected to an internal combustion engine (1) which is linked to an electric driving motor (6) by means of a generator frequency converter, an intermediate voltage circuit and a motor frequency converter. An energy-storage reservoir (7) is connected to the intermediate voltage circuit. The intermediate voltage circuit is divisible into two partial intermediate circuits (3, 4) by means of a first switch (8). Each partial intermediate circuit includes at least one driving motor (5, 6, 12) connected by means of the corresponding motor frequency converter. For the purpose of adjusting the hybrid driving system, when the voltage (U3) in the energy storage reservoir (7) is lower than the voltage of the corresponding intermediate voltage circuit, the first switch (8) arranged between two intermediate circuits (3, 4) switches off the link and the first switch (8) becomes an open conductor only.Type: GrantFiled: March 5, 2004Date of Patent: December 9, 2008Assignee: Siemens AktiengesellschaftInventors: Eugen Holl, Swen Ruppert

Patent number: 7221062Abstract: A hybrid drive system is for a vehicle and includes an intermediate circuit and an energy accumulator. The energy accumulator is connected to the intermediate circuit by way of a diode, whereby a transistor enabling current to flow in an opposite direction is connected parallel thereto. The transistor is placed in a blocking position in order to discharge the energy accumulator and the diode enables current to pass. If the energy accumulator is not used, the diode is also blocked by increasing the voltage of the intermediate circuit with the aid of the voltage on the energy accumulator. In order to charge the energy accumulator, the transistor is conductingly switched. The diode does not allow the current to pass in this direction.Type: GrantFiled: July 17, 2002Date of Patent: May 22, 2007Assignee: Siemens AktiengesellschaftInventors: Eugen Holl, Swen Ruppert

Patent number: 5994867Abstract: A method and a device for controlling a sensorless, field-oriented asynchronous machine, wherein a manipulated variable space vector and a stator frequency are calculated, by means of a two-component current control system, from which control signals are generated using a space vector modulation process. A PI controller of an EMF control system for the d-component of a calculated EMR space vector of the field-oriented control system is deactivated and its output signal set to zero at a stator frequency, determined as a function of a calculated d-component of a calculated EMF space vector and a calculated stator frequency, that is less than or equal to a first limit frequency. Thus, the method may be used for speed control of a sensorless, field-oriented asynchronous machine down to a full stop.Type: GrantFiled: June 8, 1998Date of Patent: November 30, 1999Assignee: Siemens AktiengesellschaftInventors: Gunther Birk, Eugen Holl
