AI Technical Summary
Technical Problem
The challenge of attaching bus bar holders to a cell stack is hindered by the tolerance in battery cell thickness, leading to potential misalignment and difficulty in clamping bus bars, which can affect the electrical connection between tab leads and bus bars.
Method used
A method and device for attaching bus bar holders that allow bus bars to be movable relative to the holder in the X direction, involving a comb-shaped jig to open tab leads, positioning, and controlled attachment to ensure alignment and ease of clamping without strain.
Benefits of technology
Ensures efficient attachment of bus bar holders to the cell stack while facilitating easy clamping of bus bars, reducing interference and improving the electrical connection between tab leads and bus bars.

Abstract
To easily clamp a bus bar without strain while ensuring work efficiency when attaching a bus bar holder to a cell stack. [Solution] The busbar holder mounting method includes an opening step, a positioning step, an attachment step, and a release step. The busbar holder holds busbars aligned in the X direction and allows relative movement in the X direction. In the opening step, a comb-tooth jig is inserted between the tab leads to open the tips of the tab leads in the X direction. In the positioning step, the busbar holder is gripped by a predetermined holder gripping tool and the holder gripping tool is engaged with multiple busbars, thereby positioning the multiple busbars in the X direction relative to the holder gripping tool and busbar holder. In the attachment step, the busbar holder is attached to the cell stack. In the release step, the positioning of the busbars in the X direction by the holder gripping tool is released.
