Abstract
A control device for a secondary battery using positive electrode active material made of solid solution material, comprising: a voltage detecting unit configured to detect an actual open circuit voltage value; an SOC detecting unit 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; a memory unit configured to store a voltage-SOC standard control curve which shows a relation between an open circuit voltage value and a state of charge value; a presumed voltage calculating unit configured to calculate a presumed voltage value on the basis of the actual state of charge value and the voltage-SOC standard control curve stored in the memory unit; a determining unit 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.
