Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery module cooling systems experience a decrease in cooling capacity due to the heating of compressed cooling fluids, which is particularly problematic for tightly packed batteries, and current solutions are costly and energy-intensive.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If compressed air is used for cooling tightly packed batteries, then cooling capacity is increased, but the air is heated by compression which adversely reduces cooling capacity
Solution Approach 1:
The cooling device cools the compressed air in advance before it is introduced into the housing to cool the batteries. This preliminary cooling action removes the heat generated by compression, allowing the compressed air to regain its cooling capacity without requiring additional energy input during the cooling process.
Solution Approach 2:
The heat generated by compression, which initially reduces cooling capacity, is converted into a benefit by using the warm compressed air to pre-heat the cooling device or to drive thermal processes that ultimately enhance the overall cooling efficiency of the system.
2Temperature
If compressed air is used for cooling, then cooling capacity is increased, but engineering expense and production cost increase
Solution Approach 1:
The cooling device utilizes the compressed air itself as the cooling medium, eliminating the need for separate refrigerant systems or additional cooling agents. The compressed air serves dual purposes: as the driving force for air circulation and as the cooling fluid, thereby reducing manufacturing complexity and production costs.
3Temperature
If cooling fins or refrigerating systems are added to cool compressed air, then cooling capacity is maintained, but device complexity increases
Solution Approach 1:
The cooling device merges the compression function and cooling function into a single integrated system. The cooling fins or refrigerating system are combined with the compressor unit, allowing the compressed air to be cooled within the same device structure, thereby reducing overall system complexity while maintaining cooling capacity.

AI summary
In a battery module, having a housing, at least one battery, which is disposed in the housing, at least one inlet opening for introducing a cooling fluid into the housing, and at least one outlet opening for conducting the cooling fluid out of the housing. According to the invention, compressed cooling fluid can be supplied to the at least one inlet opening using a compressor. A reduction of the cooling performance because of heating of the compressed cooling fluid is to be at least partially avoided. Furthermore, the design effort is to be low and the battery module is to be cost-effective to produce. The invention solves a problem in that the cooling fluid can be cooled by a cooling apparatus.
