Abstract

In a battery module, having a housing, at least one battery, which is disposed in the housing, at least one inlet opening for introducing a cooling fluid into the housing, and at least one outlet opening for conducting the cooling fluid out of the housing. According to the invention, compressed cooling fluid can be supplied to the at least one inlet opening using a compressor. A reduction of the cooling performance because of heating of the compressed cooling fluid is to be at least partially avoided. Furthermore, the design effort is to be low and the battery module is to be cost-effective to produce. The invention solves a problem in that the cooling fluid can be cooled by a cooling apparatus.
