1. A battery module, comprising:
a plurality of battery cells stacked one [ on ] another and respectively having electrode leads protruding in the front and rear directions of the battery module [ at a first end and a second end of the plurality of battery cells, the first end being opposite from the second end] ; and
a bus bar unit configured to integrally connect [ electrically connect ] the electrode leads of the plurality of battery cells,
wherein the bus bar unit includes:
a first bus bar frame mounted in front of [ on a first side of ] the pluarality of battery cells [ module] ;
a first bus bar coupled to the first bus bar frame and [ electrically ] connected to the electrode leads of the plurality of battery cells, which protrude to the front [ the first side of the battery module] ;
a second bus bar frame mounted behind [ on a second side of ] the plurality of battery cells [ module] ;
a second bus bar coupled to the second bus bar frame and [ electrically ] connected to the electrode leads of the plurality of battery cells, which protrude to the rear [ the second side of the battery module] ; and
a sensing bus bar configured to electrically connect the second bus bar and the first bus bar and integrally mounted to [ contacting ] the first bus bar and the second bus bar,
wherein the sensing bus bar includes an elastic bending portion which is configured to be elastically bendable and [ that is elastically bendable and is ] folded in the front and rear [ first and second ] directions of the plurality of battery cells [ module] ,
wherein the sensing bus bar has a total length that is longer than a length of the plurality of battery cells [ module ] in the front and rear [ first and second ] direction of the plurality of battery cells [ module] , and
wherein the sensing bus bar including the elastic bending portion that is folded has a shorter length between the first and second bus bars that corresponds to the length of the plurality of battery cells [ module ] in the front and rear [ first and second ] directions of the plurality of battery cells [ module ] when the bus bar unit is integrally [ electrically ] connected to the electrode leads of the plurality of battery cells [ , and
wherein the elastic bending portion has at least one fold that overlaps the sensing bus bar.]
