摘要

PURPOSE: A high-capacity battery module is provided to prevent arrangement error of the secondary battery during an assembly process and shorten assembly time. CONSTITUTION: A high-capacity battery module(101) comprises a plurality of secondary batteries(10) including electrode terminals(11) projected to outside and identification parts(13) arranged around the electrode terminals, bus bars(40) which electrically interlink the electrode terminals of adjacent secondary batteries, and a protective member(30) located between the plurality of secondary batteries and bus bar. The electrode terminals comprise positive electrode terminals and cathode terminals.
