BATTERY MODULE AND BATTERY SYSTEM WITH HEAT EXCHANGER HOUSING

A battery module comprising a liquid-tight housing and a plurality of battery cells arranged in the liquid-tight housing is disclosed. 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. 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. The secondary tempering system is configured to establish the flow of the second tempering fluid.
