Abstract
A method of inspecting an electric power storage device for a short circuit includes voltage measuring of measuring a pre-detection device voltage of the electric power storage device that is pre-charged, current detecting of detecting a temporal change in a current flowing to the electric power storage device from an external electric power supply or a stable current value of the current by continuously applying an output voltage equal to the pre-detection device voltage to the electric power storage device from the external electric power supply, and determining of determining an internal short circuit in the electric power storage device based on the detected temporal change in the current or the stable current value of the current.
