A method for reusing a secondary battery by reusing unit cells or battery modules constituting reclaimed assembled batteries (or battery packs) to reconstruct a new assembled battery is disclosed. Assembled batteries are reclaimed, and disassembled into battery modules. The battery modules are selected based on battery characteristics such as an open-circuit voltage (OCV) and the like using an absolute acceptable range and a relative acceptable range, and a new assembled battery is rebuilt. The relative acceptable range is an acceptable range which is set for each assembled battery, and is set to have its center at an average value of a battery characteristic distribution.

Method for reusing secondary battery

The present invention can include a frame member which attaches the monitor panel at a back side of a vehicle seat, a skin member covering the vehicle seat, a pad member having a seat outer shape, the frame member is harder than the pad member, and the frame member is arranged at a back side of the vehicle seat in place of the pad member and covered by the skin member and the monitor panel is attached to the frame member through the skin member.
