    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.

    摘要: Provided are a cell module and a battery system. The cell module includes: a cell fixing bracket, multiple rows of cell groups and a liquid cooling plate. Specifically, all of the cell groups are disposed on the cell fixing bracket, each row of cell group includes multiple cells, each row of cell group other than a first row of cell group and a last row of cell group has a first spacing H from an adjacent row of cell group, and has a second spacing h from another adjacent cell group, and the first spacing H is greater than the second spacing h. The liquid cooling plate is disposed between the two rows of cell groups spaced apart by the first spacing H, and is configured to regulate the temperature of multiple cells near the liquid cooling plate. The liquid cooling plate is installed between the two rows of cell groups separated by the first spacing, thus the distance between the two rows of cell groups with no liquid cooling plate disposed therebetween can be saved on the basis that the temperature of the cells can be controlled, so that the structure of the cell module can be more compact and the overall size can be small. The battery system according to the present application employs the cell module described above, so the battery system has a small overall size and is beneficial to reduce costs.
