Partitioned Power Storage Module Cooling for Compartment Heat Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing power storage module designs fail to efficiently cool multiple electrode assemblies housed in separate compartments, as heat generated in one compartment can easily be transmitted to others through partitions, leading to ineffective thermal management.
Innovation Solution
A power storage module with a case that includes partitioned compartments and dedicated cooling paths for each compartment, allowing refrigerant to flow through specific paths to efficiently cool the electrode assemblies, reducing heat transfer between compartments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If partitions are used to separate battery compartments, then spatial organization and safety isolation are improved, but heat transmission between compartments increases
Solution Approach 1:
The cooling system is segmented into independent cooling paths for each battery compartment. The first cooling path is dedicated to cooling the first battery compartment, and the second cooling path is dedicated to cooling the second battery compartment, preventing heat transmission through shared cooling structures
Solution Approach 2:
Each battery compartment is provided with localized cooling paths that are specific to that compartment. The first cooling path is located in the first case body portion facing the first compartment, and the second cooling path is located in the second case body portion facing the second compartment, ensuring localized thermal management
2Volume of stationary object
If multiple battery compartments are arranged adjacently, then space utilization is improved, but thermal management complexity increases
Solution Approach 1:
The case body is divided into multiple case body portions, with each portion containing its own dedicated cooling path. This segmentation allows adjacent battery compartments to be thermally managed independently, reducing the complexity of thermal management while maintaining compact spatial arrangement
Solution Approach 2:
The case body portions act as intermediaries that provide dedicated cooling paths between the battery compartments and the external cooling system, simplifying thermal management by providing direct, compartment-specific cooling routes

Function Achieved in This Case
This configuration enables efficient cooling of multiple electrode assemblies by isolating heat transfer between compartments, improving thermal management and reducing the risk of overheating.
Implementation Method 1
heat generated from the electrode assembly in one compartment is easily transmitted to the other compartment through the partition

AI summary
A power storage module has a case including a case body and at least one partition portion. The case body surrounds a plurality of electrode assemblies. The partition portion is located between the electrode assemblies adjacent to each other to partition an accommodation space of the case body. In the accommodation space of the case body, the partition portion forms a first compartment and a second compartment adjacent to the first compartment with the partition portion interposed between the first compartment and the second compartment. A first cooling path and a second cooling path are formed in the case, the first cooling path extends in a portion 10 of the case that faces the first compartment without the second compartment in between, and the second cooling path extends in a portion of the case that faces the second compartment without the first compartment in between.
