A battery module according to the present disclosure includes a first busbar electrically connected to a first electrode lead of a first battery cell, a second busbar electrically connected to a second electrode lead of a second battery cell, a short part which moves to the first busbar and the second busbar and comes into contact with the first busbar and the second busbar by the application of an expansion force caused by volume increase of the first battery cell to electrically connect the first busbar to the second busbar, causing a short, and a cartridge which receives or supports at least part of the first electrode lead, the second electrode lead, the first busbar, the second busbar and the short part.

Battery module and battery pack and vehicle comprising the same

A battery module, including a cell stack having a first battery cell and a second battery cell; a first bus bar connected to the cell stack and having a first polarity; a second bus bar connected to the cell stack and having a second polarity opposite to the first polarity; a short-circuit unit that moves toward the first bus bar and the second bus bar in response to receiving an expanding force caused by a volume increase of the first battery cell and the second battery cell, so that the first bus bar and the second bus bar are electrically connected to generate a short circuit; and a cartridge that at least partially accommodates each of the first bus bar, the second bus bar and the short-circuit unit.

Battery module with short-circuit unit, and battery pack and vehicle including the same

A battery module including a first bus bar electrically connected to a first electrode lead of a first battery cell; a second bus bar electrically connected to a second electrode lead of a second battery cell; a short-circuit unit moving toward the first bus bar and the second bus bar by receiving an expansive force due to a volume increase of at least one of the first battery cell and the second battery cell to electrically connect the first bus bar to the second bus bar to generate a short circuit; and a cartridge accommodating or supporting at least a portion of the first electrode lead, the second electrode lead, the first bus bar, the second bus bar and the short-circuit unit.

Battery module with short-circuit unit, and battery pack and vehicle including same

A battery module, which includes: a first bus bar electrically connected to a first electrode lead of a first battery cell; a second bus bar electrically connected to a second electrode lead of a second battery cell; a short-circuit unit configured to move toward the first bus bar and the second bus bar by receiving an expansive force due to a volume increase of the first battery cell and another battery cell adjacent to the first battery cell so that the first bus bar and the second bus bar are electrically connected to generate a short circuit; and a cartridge configured to accommodate or support at least a portion of the first electrode lead, the second electrode lead, the first bus bar, the second bus bar and the short-circuit unit.
