Abstract
An air displacer for a traction battery of a motor vehicle is configured such that, in the installed state in a battery housing of the traction battery, it at least partially fills a free volume in the battery housing and thereby at least partially displaces air in the battery housing in the event of heat generation inside the housing. The air displacer includes a vacuum bag; a foam that can be expanded using air, which is arranged in the vacuum bag; and a manually opening air inlet point. The air displacer can be transferred from an initial state in which the vacuum bag is evacuated in the closed state of the air inlet point and the foam in the vacuum bag is compressed, into an end state provided for the installed state in which air flows through the vacuum bag by manually opening the air inlet point and the foam is thereby expanded.
