A control device (20) for a secondary battery (10) using, as positive electrode material, positive electrode active material made of solid solution material, comprising: a voltage detecting unit (50) configured to detect an actual open circuit voltage value of the secondary battery; an SOC detecting unit (22) configured to detect an actual state of charge value on a basis of the actual open circuit voltage value and/or an actual current value of the secondary battery; a memory unit (24) configured to store a voltage-SOC standard control curve which shows a relation between an open circuit voltage value of the secondary battery and a state of charge value; a presumed voltage calculating unit (26) configured to calculate a presumed voltage value on the basis of the actual state of charge value detected by the SOC detecting unit and the voltage-SOC standard control curve stored in the memory unit; a determining unit (26) configured to determine sameness between the actual voltage value detected by the voltage detecting unit and the presumed voltage value calculated by the presumed voltage calculating unit. |
