Abstract
A battery module blocks current when the temperature rises, a battery pack includes the battery module, and a vehicle includes the battery pack. The battery module includes a bus bar having an approximately thin plate shape compared to a length and a width and having linear grooves provided in a left surface and a right surface along a longitudinal direction, respectively; and battery cells respectively located on the left surface and the right surface of the bus bar, physically contacting with their respective electrode leads inserted into the grooves, and electrically connected to each other with the bus bar interposed therebetween, and wherein sizes of the grooves increase in a thickness direction at a certain temperature or higher to release a physical contact between the electrode leads and the bus bar such that an electrical connection between the battery cells is released.
