Battery module, battery pack including battery module, and vehicle including battery pack

A battery module includes a plurality of battery cells, and a module case configured to accommodate the plurality of battery cells, the module case being filled with an insulating oil therein to a predetermined height. The insulating oil fills the inside of the module case in an amount covering an entire volume of the battery cells, and the insulating oil is disposed so as to be spaced apart from an inner wall of one side of the module case by a predetermined distance.

Battery module, battery pack including same battery module, and vehicle including same battery pack

A battery module includes a plurality of battery cells stacked on each other, a heatsink configured to cool the plurality of battery cells, a module case having one side to which the heatsink is mounted, the module case being configured to accommodate the plurality of battery cells, and a thermal resin disposed inside the module case. The thermal resin is filled in the module case to cover at least a portion of electrode leads of the plurality of battery cells, and the thermal resin extends alongside the heatsink.

Battery module and battery pack comprising same battery module

A battery pack includes a pack case configured to accommodate a cell module assembly in an inner space thereof and having an opening formed at one side, and a pack cover having a degassing port communicating with the inner space and configured to cover the opening of the pack case. The cell module assembly includes a cell fixing frame having an upper plate and a lower plate respectively disposed at an upper portion and a lower portion of the cell stack and in surface contact with an upper wall and a lower wall of the pack case. At least one of the upper plate and the lower plate includes at least one gas moving route formed by concavely depressing one surface in contact with the upper wall or the lower wall of the pack case along a path toward the degassing port, and at least one hole.
