Abstract
An apparatus for estimating a voltage of a secondary battery which includes a cathode including a first cathode material and a second cathode material with different activating voltage ranges, an anode including an anode material and a separator for separating the cathode from the anode. The apparatus includes a control unit configured to estimate a voltage of a secondary battery based on a circuit model including a first cathode material circuit, a second cathode material circuit and an anode material circuit, each circuit modeled to change its voltage according to a State Of Charge (SOC) of the electrode material corresponding the circuit and a current flowing through the circuit.
