1. A control device that controls a power storage device, the control device comprising:
an acquisition unit that acquires a first index value that is an index of a deterioration state of the power storage device; and
a lower limit setting unit that lowers a lower limit value of an allowable range for a second index value indicating a power storage state of the power storage device, when the first index value acquired by the acquisition unit indicates a predetermined degree of deterioration or more,
wherein the power storage device has an SOC-OCV characteristic curve including a first SOC region in which SOC is equal to or higher than a predetermined reference value and a second SOC region in which the SOC is less than the reference value,
wherein the SOC-OCV characteristic curve of the power storage device before deterioration in which the first index value does not indicate the predetermined degree of deterioration or more is different from the SOC-OCV characteristic curve of the power storage device after deterioration in which the first index value indicates the predetermined degree of deterioration or more, and
wherein an amount of change in OCV of the power storage device before and after deterioration in the first SOC region is greater than the amount of change in the OCV before and after deterioration in the second SOC region.
