Power storage pack authentication method, power storage pack, charging device, electric mobile body, and electric mobile body control device

A power storage pack comprising:

• a battery module configured to supply electric power to an electric movable body;
• and
• a controller configured to communicate with a controller of the electric movable body and a controller of a charging device, wherein
• the controller is configured to:
• wiredly transmit identification information retained in the power storage pack to the controller of the charging device after the power storage pack is detached from the electric movable body and is mounted in a charging slot of the charging device;
• wiredly receive another identification information from the controller of the charging device after a charging of the power storage pack is completed, the another identification information being received by the controller of the charging device from another power storage pack mounted in another charging slot;
• and
• transmit via near-field communication a signal including the another identification information received from the charging device after the power storage pack is detached from the charging slot and is mounted in the electric movable body, and
• the signal transmitted via the near-field communication is utilized by the controller of the electric movable body for the controller of the electric movable body to authenticate whether or not the power storage pack mounted in the electric movable body is identical to a partner device communicating via the near-field communication.

A charging device comprising:

• a plurality of charging slots;
• and
• a controller configured to communicate with a controller of a power storage pack,
• wherein the controller is configured to:
• wiredly receives identification information retained in a first power storage pack from a controller of the first power storage pack after the first power storage pack detached from an electric movable body is mounted in a first charging slot;
• wiredly transmit 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;
• wiredly transmit another identification information to the controller of the first power storage pack mounted in the first charging slot;
• after receiving a signal transmitted via near-field communication, collate whether or not the identification information included in the received signal matches the another identification information transmitted wiredly;
• and
• authenticate that the first power storage pack mounted in the first charging slot is identical to a partner device communicating via the near-field communication if the identification information included in the received signal matches the another identification information transmitted wiredly.

An electric movable body comprising:

• a motor;
• and
• a controller configured to communicate with a controller of a power storage pack,
• wherein the controller is configured, after receiving a signal via near-field communication after a first power storage pack is detached from the electric movable body and is mounted in a first charging slot of a charging device and after a second power storage pack replaceable with the first power storage pack is detached from a second charging slot of the charging device and is mounted in the electric movable body, to:
• collate whether or not identification information included in the received signal matches identification information retained in the first power storage pack;
• and
• authenticate 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 identification information retained in the first power storage pack.
