BATTERY MODULE AND BATTERY SYSTEM WITH HEAT EXCHANGER HOUSING

Provided is a battery module, comprising a liquid-tight housing and a plurality of battery cells arranged in the liquid-tight housing. A first tempering fluid is included in the liquid-tight housing in thermal contact with the plurality of battery cells and with an inner surface of the liquid-tight housing. The liquid-tight housing is constructed to allow for a flow of a second tempering fluid between the inner surface and an outer surface of the liquid-tight housing, whereby the liquid-tight housing is configured as a double-walled profile housing, wherein a second fluid channel for the flow of the second tempering fluid is integrally formed.Further provided is a battery system comprising a battery module and a secondary tempering system connected to the liquid-tight housing of the battery module and configured to establish the flow of the second tempering fluid.
