Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If air cooling method is used for battery thermal management, then the cooling structure is simple, but the cooling effect is insufficient when battery temperature is extremely high
Solution Approach 1:
The cooling system is segmented into multiple independent cooling channels formed by alternating arrangement of first cooling plates and second cooling plates. Each cooling plate has through-holes that create separate fluid flow paths, allowing the system to be divided into modular units that can be independently optimized for thermal management efficiency.
Solution Approach 2:
The cooling plates are nested between battery packs in a stacked configuration, with multiple cooling plates interleaved with battery packs to form a compact integrated structure. This nesting approach maximizes heat dissipation surface area within limited space while maintaining structural compactness.
2Temperature
If liquid cooling method is used for battery thermal management, then the cooling effect is good, but the cooling structure is complex and occupies large space
Solution Approach 1:
The cooling plates are merged with the battery pack structure to form an integrated assembly. The cooling channels are formed within the cooling plates themselves rather than requiring separate cooling components, combining the thermal management function with the structural support function in a single integrated design.
Solution Approach 2:
The cooling system transitions from traditional planar cooling arrangements to a three-dimensional stacked configuration where cooling plates are arranged in multiple layers between battery packs. This vertical stacking approach maximizes heat dissipation surface area while minimizing the horizontal footprint of the cooling system.
3Temperature
If cooling plates are arranged alternately with battery packs, then heat dissipation efficiency is improved, but the overall device height increases
Solution Approach 1:
The cooling plates are nested between battery packs in a compact stacked arrangement, with each cooling plate fitting into the interstices of the battery pack assembly. This nesting configuration achieves efficient heat dissipation through multiple cooling surfaces while maintaining a compact overall height by utilizing the vertical space between battery components.

AI summary
Disclosed in the present application are an energy storage device and a temperature regulating structure thereof. The temperature regulating structure of the energy storage device comprises: a housing, and a temperature regulating plate fixedly connected to the housing, wherein the housing and the temperature regulating plate form a first heat insulation cavity, and/or the housing is provided with a second heat insulation cavity. In the temperature regulating structure of the energy storage device, the first heat insulation cavity is formed by the housing and the temperature regulating plate and/or the housing is provided with the second heat insulation cavity. Use of the first heat insulation cavity and the second heat insulation cavity can reduce the heat exchange of the temperature regulating plate with the outside by means of the housing, thereby reducing the impact of the external environment on the temperature regulating plate and improving the regulation efficiency of the temperature regulating plate.
