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)

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.
