Abstract:
1. A circuit model for a battery comprising: a voltage source; an ohmic variable resistor electrically coupled in series with the voltage source; a first RC-pair electrically coupled in series with the ohmic variable resistor and the voltage source, said first RC-pair including a first capacitor and first variable resistor electrically coupled in parallel; and a second RC-pair electrically coupled in series with the first RC-pair, the ohmic variable resistor and the voltage source, said second RC-pair including a second capacitor and a second variable resistor electrically coupled in parallel, wherein each of the ohmic variable resistor, the first variable resistor and the second variable resistor have a variable resistance that changes in response to a voltage potential across each resistor.
