Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
Collects parameters of battery cells:
- Nominal charge
- OCV versus SOC characteristic
- Inner resistance; can be calculated from OCVmax / short-circuit current (at OCVmax)
- Array of records
rcDatafor battery models comprising RC-elements
Note
If useLinearSOCDependency=true, the OCV versus SOC table is built up internally from OCVmax, OCVmin, SOCmax, SOCmin.
Otherwise, the OCV versus SOC table has to be specified: 1st column = SOC values in ascending order, 2nd column = corresponding OCV values with respect to OCVmax.
The size of the array rcData has to be defined as parameter nRC.
The sum of the resistances rcData.R must not exceed the total inner resistance Ri.
