1. A case for a battery, comprising:
a thermal management component configured to adjust temperature of a battery cell accommodated in the case;
a first wall provided with a through hole, the through hole being configured to communicate a gas inside and outside the case; and
a heat conducting component attached to the thermal management component and the first wall, the heat conducting component being configured to conduct heat of the thermal management component to the first wall, so that the first wall condenses a gas flowing from the outside of the case to the inside of the case before the gas flowing through the through hole;
wherein the first wall comprises a first sub-wall and a second sub-wall, wherein a cavity is formed between the first sub-wall and the second sub-wall, the first sub-wall is an inner wall of the case, the second sub-wall is an outer wall of the case, the through hole is disposed on the first sub-wall, and the first wall is configured to condense a gas flowing into the cavity through the second sub-wall in the cavity; and
wherein a pressure balancing mechanism is disposed on the second sub-wall, the gas flowing into the cavity from the outside of the case through the pressure balancing mechanism flows into the inside of the case through the through hole.
