Abstract
A power storage apparatus includes a first storage module, a second storage module, a charge-discharge circuit, and circuitry. The first storage module includes a first detector to detect first current input to and output from the first capacitor. The second storage module includes a second detector to detect second current input to and output from the second capacitor. The charge-discharge circuit is connected to the first capacitor and the second capacitor to charge and discharge the first capacitor and the second capacitor. The circuitry is configured to control the charge-discharge circuit to control charging and discharging between the first capacitor and the second capacitor. The circuitry is configured to determine whether or not at least one of the first detector and the second detector is to be corrected based on the first current and the second current during charging and discharging between the first capacitor and the second capacitor.
