Battery pack and method of inspecting storage state of secondary battery in battery pack

A method of inspecting a storage state of a secondary battery in a battery pack, the battery pack with a plurality of secondary batteries and an inspection circuit, the method comprising:

• when the plurality of secondary batteries are classified into a first secondary battery group and a second secondary battery group, the first secondary battery group being configured of secondary batteries selected from the plurality of secondary batteries, the second secondary battery group being configured of remaining secondary batteries not belonging to the first secondary battery group, and the secondary batteries each being given an identification mark previously
• allowing the inspection circuit to create a first data string of the secondary batteries configuring the second secondary battery group, based on a predetermined arithmetic rule, from the identification marks of the secondary batteries configuring the first secondary battery group, to obtain a second data string by examining the identification marks of the secondary batteries configuring the second secondary battery group, subsequently to compare the first data string with the second data string, and to stop a function of the battery pack when the first data string and the second data string do not match.

• in charging the secondary batteries, allowing the inspection circuit to form a charge current change in the secondary batteries configuring the first secondary battery group into data to create a first data string of the secondary batteries configuring the second secondary battery group based on a predetermined arithmetic rule, to form a charge current change in the secondary batteries configuring the second secondary battery group into data to obtain a second data string, subsequently to compare the first data string with the second data string, and to stop a function of the battery pack when the first data string and the second data string do not match.
