Abstract
A battery module includes a plurality of unit cells, each unit cell having a first terminal and a second terminal, the plurality of unit cells including at least a first unit cell and a second unit cell, and a bus bar electrically connecting the first terminal of the first unit cell to one of the first and second terminals of the second unit cell, the bus bar including an insertion part therein, the insertion part being configured to receive a sensing member and connect the sensing member to the bus bar.
Claims16
A battery module, comprising:
- a plurality of unit cells, each unit cell having a first terminal and a second terminal, the plurality of unit cells including at least a first unit cell and a second unit cell;
- and
- a bus bar electrically connecting the first terminal of the first unit cell to one of the first and second terminals of the second unit cell, the bus bar including an insertion part therein, the insertion part being configured to receive a sensing member and connect the sensing member to the bus bar,
- wherein:
- the sensing member is disposed in the insertion part and is connected to the bus bar, the sensing member being connected to the bus bar by a press-fit connection,
- the sensing member includes an elastic detection part configured to be pressed from an undeformed state to a pressed state when inserted into the insertion part, and
- the detection part is shaped as an elliptical, circular, or polygonal ring having a width in the undeformed state that is larger than a width of the insertion part.
