Secondary battery cell, battery pack, and electric power consumption device

摘要

Provided is a secondary battery cell that can certainly prevent detachment of an integrated circuit from the secondary battery cell and attachment of the integrated circuit to another secondary battery cell, a battery pack including such secondary battery cells, and an electric power consumption device including such a battery pack.;A secondary battery cell 20 of the present invention includes an integrated circuit (an IC chip) 50 that has stored identification information, and the integrated circuit 50 is driven by power from the secondary battery cell. A battery pack of the present invention includes secondary battery cells each including an integrated circuit (an IC chip) that has stored identification information, and the integrated circuits are driven by power from the secondary battery cells. An electric power consumption device of the present invention contains a battery pack that includes secondary battery cells each including an integrated circuit (an IC chip) that has stored identification information, and the integrated circuits are driven by power from the secondary battery cells.

主权项

1. A secondary battery cell comprising:
an integrated circuit having stored identification information of the secondary battery cell, wherein the integrated circuit is configured to:
receive a command, from a control circuit, to inquire about the identification information of the secondary battery cell, wherein the command from the control circuit is received based on a position of the secondary battery cell among a plurality of secondary battery cells; andsend the identification information, to the control circuit, based on the received command, wherein power supply of the secondary battery cell is controlled by the control circuit based on matching of the identification information with identification information of each of the plurality of secondary battery cells stored in the control circuit.
