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