1. A method for inspecting an energy storage device, the method comprising:
estimating a degree of degradation of the energy storage device;
determining, based on the estimated degree of degradation, a measurement condition such that time required to measure a full charge capacity of the energy storage device decreases or increases;
measuring the full charge capacity according to the determined measurement condition;
determining whether the determined measurement condition meets a predetermined requirement; and
when determination is made that the measurement condition meets the predetermined requirement,
performing the measurement of the full charge capacity, and
determining, based on the measured full charge capacity, whether the energy storage device needs to be replaced, wherein
determining, according to the estimated degree of degradation, the measurement condition includes determining the measurement condition such that the measurement condition meets the predetermined requirement.
