Patent ID: 11390175

Abstract:
An accumulator for a hybrid or electric vehicle may include a housing having two shell-shaped housing parts abutting one another in a Z direction and forming an interior of the housing, a plurality of battery modules having a plurality of battery cells arranged in the interior of the housing, and at least one cooling device having a cooling chamber, through which a fluid is flowable, a fluid inlet for introducing the fluid into the cooling chamber, and a fluid outlet for discharging the fluid from the cooling chamber. The cooling chamber may be formed in a respective one of the two housing parts via a heat-conducting limiting plate, which may be spaced apart from a bottom of the respective housing part and may be aligned transversely to the Z direction and may separate the cooling chamber from the interior in a fluid-tight manner inside the respective housing part. At least some of the battery modules may abut on the limiting plate facing away from the cooling chamber so as to transfer heat.
