US Patent:
20140028088, Jan 30, 2014
Filed:
Jul 24, 2013
Appl. No.:
13/949344
Inventors:
- Yongin-si, KR
- Stuttgart, DE
Joachim Rischen - Lake Orion MI, US
Assignee:
Samsung SDI Co., Ltd. - Yongin-si
Robert Bosch GmbH - Stuttgart
International Classification:
H02J 7/00
G01R 27/26
B60R 16/02
US Classification:
307 91, 320166, 324679, 702 65
Abstract:
A battery system comprises at least one battery cell and a high-voltage network connected thereto which includes a pre-charge circuit having at least one pre-charge resistor. The battery system further comprises a component including a link capacitor with a specific capacitance. A method for controlling the battery system includes measuring a first voltage at the link capacitor before charging, charging the link capacitor, and measuring a second voltage at the link capacitor after charging. The method further includes forming a voltage difference from the first and the second voltage, and determining an energy received by the pre-charge resistor based on the voltage difference at the link capacitor and based on the capacitance of the link capacitor.

US Patent:
20130241567, Sep 19, 2013
Filed:
May 17, 2011
Appl. No.:
13/809890
Inventors:
Andre Boehm - Kornwestheim, DE
Ralf Piscol - Herrenberg, DE
Joachim Rischen - Lake Orion MI, US
Assignee:
Robert Bosch GmbH - Stuttgart
International Classification:
G01R 31/36
US Classification:
324434
Abstract:
A method for determining the life expectancy of at least one battery cell, according to which a value of at least one physical variable acting on the battery cell and/or a number of executions of at least one process taking place in the battery cell is determined, and the value of the physical variable and/or the number of executions of processes is used as a basis for determining the life expectancy. The physical variable and/or the number of executions of processes taking place in the battery cell is determined for a plurality of operating cycles, and the frequency of the occurrence of defined values of the physical variable and/or the frequency of the number of executions of at least one defined process is stored.
