Abstract
An inspection method of a present electrical storage device includes: constituting a circuit with the electrical storage device being charged and a power supply, and passing a current by the power supply to the circuit in a direction of charging or discharging the electrical storage device; and in passing the current, determining the quality of the electrical storage device based on a converging state of the passing current. In passing the current, an output voltage of the power supply is changed from an initial value with the passage of time.
