Problem
Current accumulators for hybrid or electric vehicles are heavy, require significant installation space, and have high production costs due to multiple cooling plates and fluid connecting elements, leading to complex sealing challenges.
Innovation Solution
The accumulator design integrates a cooling device with a heat-conducting limiting plate within the housing, reducing the number of parts and using a plastic housing with a shield layer for weight reduction and improved electromagnetic compatibility, while simplifying assembly and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If multiple cooling plates and fluid connecting elements are used, then heat dissipation effectiveness is improved, but weight increases
Solution Approach 1:
The patent combines multiple separate cooling plates into a single integrated cooling plate that serves all battery modules. This cooling plate includes multiple cooling channels formed directly within it, eliminating the need for separate cooling plates and fluid connecting elements, thereby reducing weight while maintaining heat dissipation effectiveness.
Solution Approach 2:
The single cooling plate performs multiple functions: it cools multiple battery modules simultaneously and integrates the functions of what would otherwise require separate cooling plates and connecting elements. This multi-functional design reduces the overall number of components and weight.
2Temperature
If multiple cooling plates and fluid connecting elements are used, then heat dissipation effectiveness is improved, but installation space requirement increases
Solution Approach 1:
The patent merges multiple cooling plates and fluid connecting elements into a single integrated cooling plate with multiple cooling channels. This consolidation reduces the overall space occupied by the cooling system, decreasing the installation space requirement while maintaining effective heat dissipation across all battery modules.
3Temperature
If multiple cooling plates and fluid connecting elements are used, then heat dissipation effectiveness is improved, but production cost increases
Solution Approach 1:
The patent integrates multiple cooling plates and fluid connecting elements into a single cooling plate component. This reduction in part count simplifies the manufacturing process, reduces assembly complexity, and lowers production costs while maintaining the heat dissipation effectiveness through the integrated cooling channels.
4Temperature
If multiple cooling plates and fluid connecting elements are used, then heat dissipation effectiveness is improved, but sealing complexity increases
Solution Approach 1:
The patent combines multiple cooling plates and fluid connecting elements into a single integrated cooling plate, thereby reducing the number of sealing joints required. This integration simplifies the sealing system and reduces sealing complexity while maintaining effective heat dissipation through the integrated cooling channels.

AI summary
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.
