Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy storage containers have low energy density due to the limited space occupied by traditional battery cabinets, and there is a need to enhance safety and thermal management to prevent risks such as thermal runaway.
Innovation Solution
The energy storage container is designed with multiple consecutively arranged battery compartments sharing a wall, a main control box compartment perpendicular to these compartments, and includes features like corrugated side walls, insulation, and support beams to increase energy density, safety, and thermal management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional battery cabinets are used for energy storage, then structural simplicity is maintained, but space utilization is reduced and energy density is low
Solution Approach 1:
The energy storage container is divided into multiple battery compartments arranged in parallel, each capable of independently accommodating batteries. This segmentation eliminates the need for traditional battery cabinets while maintaining structural organization, thereby increasing space utilization and energy density without excessive complexity
Solution Approach 2:
The battery compartments are designed with universal characteristics, sharing common walls and support structures. The compartments can accommodate different battery configurations and include integrated thermal management and sealing features, reducing the need for additional specialized components and improving overall space efficiency
2Quantity of substance
If battery compartments are arranged to maximize space utilization, then energy density increases, but thermal management and safety become more challenging
Solution Approach 1:
By dividing the energy storage container into multiple separate battery compartments with shared walls, the patent isolates thermal risks to individual compartments. This segmentation prevents thermal runaway from spreading across the entire system while maintaining high space utilization through compact arrangement
Solution Approach 2:
The shared walls between battery compartments act as thermal barriers and intermediaries that can prevent heat transfer between adjacent compartments. These walls may include insulation layers or fire-resistant materials that mediate thermal management and enhance safety without compromising space efficiency
3Reliability
If compartment doors are sealed to prevent water ingress, then protection performance improves, but manufacturing precision requirements increase
Solution Approach 1:
The patent employs seal rings made of flexible sealing materials at the interfaces between compartment doors and walls. These flexible seals accommodate manufacturing tolerances and assembly variations while maintaining effective water and dust protection, thereby improving reliability without requiring excessive manufacturing precision
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design increases energy density, enhances safety by limiting thermal runaway risks, and improves space utilization and maintainability while maintaining structural integrity and preventing water ingress.
Implementation Method 1
an outer wall of the multiple battery compartments is a first sandwich structure, where the first sandwich structure is provided with first insulation cotton
Implementation Method 2
a side wall shared by the two adjacent battery compartments is a corrugated plate
Implementation Method 3
a first seal ring is provided between the first compartment door and the first wall so that when the first compartment door is closed, the battery compartment in which the first compartment door is located is sealed
