An accumulator assembly for a hybrid or electric vehicle may include a plurality of battery cells respectively having mutually opposite bearing faces. The battery cells may be stacked in a stacking direction facing one another with the bearing faces to form a battery block. The assembly may also include a cooling device including a plurality of cooling elements through which a flow of cooling fluid is passable. The plurality of cooling elements may be disposed between neighbouring battery cells and braced in the stacking direction. A respective cooling element of the plurality of cooling elements may at least one of i) include and ii) be formed by a compressible porous intermediate insert having a plurality of pores through which a flow of the cooling fluid is passable. The intermediate insert may be disposed between and connected in a heat-transmitting manner to respective neighbouring battery cells.

Accumulator assembly

A heat exchanger may include a heat exchange surface partially coated with a heat-conducting layer. The heat exchange surface may include a plurality of contact regions coated with the heat-conducting layer and a plurality of insulating regions that are not coated with the heat-conducting layer. The heat exchange surface may further include a degree of coverage of the heat-conducting layer that varies to compensate at least one of at least one hot spot and at least one cold spot. The at least one hot spot and the at least one cold spot may be included within at least one of the heat exchange surface and a plurality of energy storage elements of an energy store that contacts the heat exchange surface.

A temperature control device for a battery may include a fluid duct being flowable at least one of through and around by a fluid. The fluid duct may be delimited by at least one duct wall composed of an electrically conductive material. An outer side of the duct wall facing away from the fluid may include at least one electrically insulating insulation layer disposed thereon via at least one of a screen printing process and a stencil printing process. The at least one insulation layer may be composed of a plastic material.

Temperature control device for controlling the temperature of a battery

A cooling device for a battery system may include at least two battery units. The cooling device may include at least a first and a second cooling plate able to be flowed through respectively by a coolant. The first and second cooling plate may be arranged respectively for thermal coupling with a respective battery unit. The first and second cooling plate each may include a first fluid inlet, which is connected fluidically with a first fluid outlet via a first fluid duct extending along an extent direction, and a second fluid inlet, which is connected fluidically with a second fluid outlet via a second fluid duct extending along the extent direction.
