1. A battery module, including:
- a housing;
at least one battery disposed in the housing;
at least one inlet opening for introducing a compressed cooling fluid into the housing, the compressed cooling fluid being compressed by a compressor; and
at least one outlet opening for carrying the compressed cooling fluid out of the housing,wherein the housing is configured to conduct the compressed cooling fluid from the at least one inlet opening to the at least one outlet opening past the at least one battery, andwherein the at least one battery is exposed to and contacted by the compressed cooling fluid such that the compressed cooling fluid absorbs heat from the at least one battery as the compressed cooling fluid is conducted from the at least one inlet to the at least one outlet, andwherein the battery module includes a relief device fluidly connected to the at least one outlet opening and configured to expand the cooling fluid discharged from the at least one outlet opening so as to reduce a pressure of the discharged cooling fluid.

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.

15. A method for cooling at least one battery, disposed in a housing, having the steps of:
-
compressing a cooling fluid with a compressor; introducing the compressed cooling fluid into the housing via at least one housing inlet; conducting the compressed cooling fluid from the at least one housing inlet to at least one housing outlet; exposing the at least one battery to the compressed cooling fluid and contacting the at least one battery with the compressed cooling fluid as the compressed cooling fluid is being conducted from the at least one housing inlet to the at least one housing outlet such that the at least one battery is cooled with the compressed cooling fluid; conducting the compressed cooling fluid out of the housing via the at least one housing outlet to a pressure relief device which is fluidly connected to the at least one housing outlet; and reducing the pressure of the cooling fluid conducted out of the housing using the pressure relief device, wherein the cooling fluid is cooled. - View Dependent Claims (16, 17, 18, 19, 20, 21)
