Information
This is the main part of the battery model. The battery cell can be used in a number of ways, for instance, the cell can be connected in series to form a battery pack.
The cell has two main circuits with a voltage source and a current source, respectively, connected to variable capacitors and variable resistors. The state of the battery is fed back to the battery cell as input to the variable capacitors and resistors.
