Title:
BATTERY PACK AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
Japanese Patent JP2018010843
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a compact battery pack and a manufacturing method therefor.SOLUTION: A battery pack 100 includes: a plurality of electric cells 11A-11D laminated in the thickness direction; and electrode tabs 15, 16 and a metal member 27 which electrically connect mutually neighboring electric cells and also electrically connect a bus bar 31 which detects the voltage of one or more electric cells to the plurality of neighboring electric cells. The electrode tabs and the metal member configures a first region A, in which a plurality of neighboring electric cells are mutually electrically connected, and a second region B in which the plurality of neighboring electric cells are electrically connected to the bus bar. The first region is formed in parallel with the flat surface of a cell body 12. A second region is formed in a manner to intersect with the first region.SELECTED DRAWING: Figure 18
