Battery system for an electric vehicle

An electric vehicle, comprising:

• a battery system;
• and
• a cooling circuit in which a coolant circulates;
• wherein the battery system includes:
• at least one battery module, which has a plurality of battery cells in a module housing;
• and
• a system housing, which has a separate receiving space for each battery module, which is delimited by two support walls that run parallel to one another and are spaced apart from one another, and into which the respective battery module is inserted;
• wherein the module housing has two housing walls, which run parallel to one another and which are spaced apart from one another, and which are each supported in a planar manner with an outer side on an inner side of the respective support wall;
• wherein the respective support wall has at least one cooling duct for guiding a coolant;
• wherein the respective support wall has, on its upper side or on its lower side, screw openings, into which screws are screwed;
• wherein the module housing has screw flanges, which are complementary to the screw openings, comprising through openings, through which the screws are guided, in order to fix the respective screw flange to the support wall;
• and
• wherein the cooling ducts of the support walls are integrated into the cooling circuit so that the coolant is flowable through the cooling ducts.
