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