摘要： The present application provides a battery module and an electric vehicle. The battery module includes a case, a longitudinal beam, and a tray. The case is provided with exhaust ports. The longitudinal beam is disposed in the case and abuts against a bottom surface of the case to partition accommodating areas in the case on both sides of the longitudinal beam along a width direction. The tray is disposed in one of the accommodating areas and is configured to install a battery cell. A through hole opposite to an end of the battery cell is defined on the tray, the tray is spaced from the bottom surface of the case to define a pressure relief cavity, the through hole and the exhaust ports are respectively communicated with the pressure relief cavity. The accommodating areas located on both sides of the longitudinal beam in the case are partitioned by the longitudinal beams, so that gas and ejections discharged from the thermal runaway battery cell will not contact the battery cell in the accommodating area on another side, so as to avoid that the accommodating area on the other side is affected to cause thermal runaway of the battery cells in the whole case.
