Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
The battery is modeled by open-circuit voltage (OCV) dependent on state of charge (SOC), self-discharge and inner resistance, as implemented in partial BaseCellStack.
This model can be used for a single cell Ns = Np = 1 as well as a stack built from identical cells.
For details, see concept and parameterization.
Note
Parameter record array rcData contained in parameter record cellData is neglected.
