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