Abstract:
To determine in a simple and unequivocal manner whether measurement contacts at which a voltage is to be measured have been properly contacted in a measurement system, in the measurement system, after a discharge switch connecting a charging circuit to a voltage measurement device is closed, the charging circuit is discharged via an internal resistance of the voltage measurement device. When the discharge switch is closed, after a measurement switch connecting the voltage measurement device to the measurement contacts is closed, it is established whether the electrical system is contacted with the measurement system by analyzing the voltage curve at the voltage measurement device after closure of the measurement switch. Advantageously, after the discharge switch is closed, the charging circuit is discharged via a discharge resistor connected in series or in parallel with the voltage measurement device and via the internal resistance.

Abstract:
The invention relates to a method for conditioning a battery module, in particular a battery module of a traction battery, to a predetermined target voltage. The invention also relates to an associated system. The battery module is charged or discharged with a charging current by a conditioning unit or a charging apparatus, until a voltage, which drops between a positive and a negative terminal of the battery module, reaches a first switch-off voltage. When the first switch-off voltage is reached, the charging current is switched off and a relaxation curve between the positive and negative terminals of the battery module is measured by the conditioning unit for a predetermined period-of-time. A model of the battery module is derived from this measured relaxation curve by an analysis unit, which model is used to determine the entire relaxation curve. A second switch-off voltage is then determined from the entire determined relaxation curve by the analysis unit in such way that, after the charging current has been switched off, when the second switch-off voltage has been reached, the predetermined target voltage is assumed as the open-circuit voltage of the battery module. The battery module then continues to be charged or discharged with the charging current, until the second switch-off voltage is reached by the voltage dropping between the positive and negative terminal of the battery module. The charging current is then switched off and the predetermined target voltage is set at the battery module as a result of the relaxation curve.
