Battery pack including a case with first and second sealing members

A battery pack comprising:

• a plurality of battery cells each comprising a first end portion and a second end portion that correspond to opposite ends in a length direction of a respective battery cell of the plurality of battery cells, each battery cell comprising an insulative layer on an outer surface thereof;
• a case having an accommodation space in which each of the plurality of battery cells is located, the accommodation space being configured to contain a cooling fluid for cooling the plurality of battery cells, the case comprising a first cover covering the first end portion of a battery cell of the plurality of battery cells, the first cover comprising a first terminal hole through which the first end portion of the battery cell of the plurality of battery cells is exposed;
• and
• first and second sealing members adjacent to the first end portion of the battery cell of the plurality of battery cells, the first and second sealing members surrounding the first terminal hole and configured to block gaps between the first cover and the first end portion of the battery cell of the plurality of battery cells to prevent cooling fluid leaving the accommodation space through the first terminal hole,
• wherein an end of the insulative layer at the first end portion of the battery cell of the plurality of battery cells is between the first terminal hole and the second sealing member, and
• wherein the insulative layer extends to the first end portion of the battery cell of the plurality of battery cells while surrounding an entire side surface of the battery cell of the plurality of battery cells for providing electrical insulation from the cooling fluid and the insulative layer is terminated at the first end portion of the battery cell of the plurality of battery cells.
