Secondary battery module with a short circuit connection member

A secondary battery module comprising:

• a plurality of secondary battery units comprising a first secondary battery unit and a last secondary battery unit, each of the plurality of secondary battery units comprising at least one secondary battery, each secondary battery comprising an electrode assembly, a case accommodating the electrode assembly, and first and second electrode terminals electrically connected to the electrode assembly, wherein for only the first secondary battery unit of the plurality of secondary battery units, each of the corresponding at least one secondary batteries further comprises a short-circuit member electrically connected to the corresponding first electrode terminal and protruding to the outside of the corresponding case upon the internal pressure of the case reaching a high-pressure condition;
• at least one fuse connecting at least two of the plurality of secondary battery units to one another in series;
• and
• a short circuit connection member having a first side facing each of the short-circuit members of the at least one secondary battery of the first secondary battery unit and a second side electrically connected to the second electrode terminal of a secondary battery of the last secondary battery unit of the plurality of secondary battery units.
