Abstract

A battery system for an electric vehicle may include at least one battery module, which may have a plurality of battery cells in a module housing, and a system housing, which may have a separate receiving space for each battery module, which may be delimited by two support walls that run parallel to one another and may be spaced apart from one another, and into which the respective battery module may be inserted. The module housing may have two housing walls, which may run parallel to and may be spaced apart from one another, and which may be each supported in a planar manner with an outer side on an inner side of the respective support wall. The respective support wall may have at least one cooling duct for guiding a coolant, and, on its upper or lower side, screw openings, into which screws may be screwed. The module housing may have screw flanges complementary to the screw openings comprising through openings, through which the screws may be guided to fix the respective screw flange to the support wall.
