Claim 0:
1. A non-welding type battery module comprising:
a plurality of battery cells;
an upper base plate disposed on an upper portion of the battery cells;
a lower base plate disposed on a lower portion of the battery cells;
a module fixing member coupled between the upper base plate and the lower base plate;
a bus bar member seated on the upper base plate and the lower base plate and electrically connected to upper and lower electrode portions of the battery cells; and
a battery cell support member disposed between the upper base plate and the lower base plate and configured to position the plurality of battery cells in place,
wherein the bus bar member includes a plate-shaped conductive plate on which an electrode contact portion, to which a battery cell is electrically connected, and a connection portion, which has a terminal hole perforated therein, are defined,
the electrode contact portion includes a plurality of upper deformation protrusions protruding upward from the plate-shaped conductive plate and a plurality of lower deformation protrusions protruding downward from the plate-shaped conductive plate while being in contact with the upper deformation protrusions,
the battery cell support member includes a plate-shaped cell support plate, in which a cell seating hole perforated to allow the battery cell to be inserted therethrough and a support hole perforated to allow the module fixing member to be inserted therethrough are defined, and a connection protrusion which is disposed to be located below the connection portion and in which a module connection hole is perforated,
the connection protrusion is configured to have a thickness less than a thickness of the plate-shaped cell support plate so that an insertion space is disposed between the connection portion and the connection protrusion, and
each of the upper base plate and the lower base plate includes a plate-shaped body on which at least one coupling portion having a coupling hole perforated therein and a close contact protrusion protruding are defined.
