Abstract
A battery housing for a motor vehicle battery includes a housing for accommodating at least one battery cell in an interior space delimited by the housing; a drainage device communicates with the interior space; a detection device detects an air moisture content and/or a liquid fill level in the interior space; and an evaluation unit which is connected to the detection device. The evaluation unit is connected to the drainage device and the drainage device is designed to open and/or close in a manner dependent on the liquid fill level ascertained in the evaluation unit. By way of the linking of the drainage device to the detection device by way of the evaluation unit, it can be ensured that the drainage device is opened only in particularly expedient situations, such that good protection of a motor vehicle battery against moisture is made possible.
