Abstract

Controller of power storage pack performs communication for authentication with controller of an electric moving body according to the pattern of a current flowing through a power line in a state where power storage pack is mounted to electric moving body. Controller of power storage pack measures contact resistance between power storage pack and the electric moving body based on voltage of the power line on power storage pack side, voltage of the power line on the electric moving body side received from controller of the electric moving body, and current when communication for authentication is performed according to the pattern of a current flowing through the power line.
