1. A power storage pack authentication method comprising:
transmitting, by a controller of an electric movable body, a first signal including identification information identical to identification information retained in a first power storage pack via near-field communication when the first power storage pack is detached from the electric movable body;
after a controller of a charging device receives the first signal transmitted via the near-field communication and after the first power storage pack detached from the electric movable body is mounted in a first charging slot of the charging device, transmitting via wire, by the controller of the charging device, the identification information received from the electric movable body to a controller of a second power storage pack which is replaceable with the first power storage pack and which is mounted in a second charging slot;
transmitting via near-field communication, by the controller of the second power storage pack, a second signal including the identification information received from the charging device after the second power storage pack detached from the second charging slot is mounted in the electric movable body;
after the controller of the electric movable body receives the second signal transmitted via the near-field communication, collating, by the controller of the electric movable body, whether or not the identification information included in the second signal received by the controller of the electric movable body matches the identification information retained in the first power storage pack; and
authenticating that the second power storage pack mounted in the electric movable body is identical to a partner device communicating via the near-field communication as a result that the identification information included in the second signal received from the second power storage device matches the identification information retained in the first power storage pack.
