Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional energy storage containers face challenges in achieving uniform temperature control, leading to potential safety issues and reduced battery lifespan due to centralized air conditioning setups, which inadequately cool multiple battery clusters and result in temperature inconsistencies.
Innovation Solution
The implementation of a distributed air conditioning system where each battery cluster is paired with a corresponding air conditioner, forming a ring network for coordinated temperature control, allowing for efficient heat dissipation and adaptive cooling capacity allocation to ensure uniform temperature across the energy storage container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a centralized air conditioning system is used to cool multiple battery clusters, then device complexity is reduced, but temperature uniformity deteriorates leading to inconsistent cooling across battery clusters
Solution Approach 1:
The centralized air conditioning system is segmented into multiple distributed air conditioners, with each air conditioner dedicated to cooling a specific battery cluster. This segmentation enables localized temperature control for each battery cluster, ensuring uniform cooling across all clusters while maintaining manageable system complexity through modular deployment
2Quantity of substance
If one air conditioner serves multiple battery clusters, then the quantity of air conditioners is reduced, but cooling effectiveness deteriorates due to inadequate heat dissipation for each cluster
Solution Approach 1:
The air conditioning resources are segmented and allocated to individual battery clusters, creating a one-to-one correspondence between air conditioners and battery clusters. This ensures that each battery cluster receives dedicated cooling capacity sufficient for its heat dissipation needs, particularly during charging and discharging operations
Solution Approach 2:
Each air conditioner is positioned and configured to provide localized cooling quality tailored to its corresponding battery cluster's specific thermal requirements. This local quality approach ensures optimal cooling effectiveness for each cluster without compromising the overall system's reliability
3Device complexity
If air conditioners are not evenly distributed in the energy storage container, then installation complexity is reduced, but temperature control uniformity deteriorates
Solution Approach 1:
The air conditioners are segmented and distributed evenly throughout the energy storage container, with each air conditioner positioned near its corresponding battery cluster. This even distribution ensures uniform temperature control across the entire container while maintaining a systematic and organized installation structure
Solution Approach 2:
The air conditioners are distributed across multiple spatial dimensions within the container, including different heights and lateral positions. This multi-dimensional distribution approach ensures comprehensive temperature control uniformity while providing a structured installation pattern that balances complexity and performance

AI summary
The energy storage container includes a container controller, a plurality of battery clusters, and a plurality of air conditioners. The plurality of air conditioners is evenly distributed in at least one of a door or a side wall of the energy storage container. Each battery cluster includes a plurality of battery modules connected in series. Each battery cluster has a corresponding air conditioner. The container controller jointly controls the plurality of air conditioners to adjust internal temperature of the energy storage container. The air conditioners in the energy storage container are disposed in an evenly distributed manner rather than a conventional centralized manner. In addition, the air conditioners are disposed in a correspondence with the battery clusters, so that the battery clusters can be effectively cooled. This ensures consistency between capacities of the battery clusters as far as possible, ensures operation safety of the battery clusters.
