Modelica.Electrical.Batteries.BatteryStacks.CellStackBattery with open-circuit voltage dependent on state of charge, self-discharge and inner resistance
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.
Parameter record array rcData contained in parameter record cellData is neglected.

Modelica.Electrical.Batteries.BatteryStacks.CellRCStackBattery with open-circuit voltage dependent on state of charge, self-discharge, inner resistance and a series of RC-elements
Extends the model CellStack by a series of RC-elements, describing the transient behaviour of the battery.
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.
Parameter record array rcData contained in parameter record cellData has to be specified.
The total inner resistance is the sum of the resistance of resistor r0 and the sum of the resistances of the resistors of the RC-elements.
