PROBLEM TO BE SOLVED: To provide a power storage device which can determine whether or not to correct the error that detection units operable to detect a current include on the whole, with good accuracy, and which can sufficiently reduce an expected value of the error that the detection units include on the whole.SOLUTION: A power storage device comprises: a first power-storage module having a first capacitor and a first detection unit operable to detect an input/output current of the first capacitor; a second power-storage module having a second capacitor and a second detection unit operable to detect an input/output current of the second capacitor; a charge/discharge circuit which forms a current path between the first and second capacitors; and a control unit operable to control the charge/discharge between the first and second capacitors through the charge/discharge circuit. The control unit determines whether or not to perform the correction on the first and second detection units based on a detection value of the first detection unit and a detection value of the second detection unit during charge/discharge between the first and second capacitors.SELECTED DRAWING: Figure 7
