Battery Pack Supporting Blocks Reduce Deflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery packs experience deflection and vibration due to the weight of stacked unit battery cells, which can lead to reduced efficiency and increased resistance.
Innovation Solution
The implementation of supporting blocks, which are elastically deformable and rest on adjacent unit batteries, are placed between vertically or horizontally stacked battery modules to distribute weight uniformly and reduce deflection and vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If unit battery cells are stacked to form battery modules, then the energy capacity of the battery pack is increased, but deflection and vibration occur due to the weight of the stacked cells
Solution Approach 1:
The battery pack is divided into multiple battery modules, each containing stacked unit battery cells. Supporting blocks are introduced as separate structural elements to bear the weight of the stacked cells, separating the energy storage function from the mechanical support function. This segmentation allows the battery cells to be stacked for increased capacity while the supporting blocks prevent deflection and vibration.
2Quantity of substance
If battery modules are vertically and horizontally stacked to increase capacity, then more energy is stored, but the structural stability deteriorates due to accumulated weight
Solution Approach 1:
Supporting blocks are introduced as intermediary structural elements between stacked battery modules. These blocks act as mediators that bear and distribute the accumulated weight from vertically and horizontally stacked modules, preventing structural deformation while allowing the modules to be configured for maximum energy storage.
3Stability of the object's composition
If supporting blocks are added to reduce deflection, then structural stability is improved, but device complexity increases
Solution Approach 1:
The supporting blocks are designed as simple, inexpensive structural elements that can be easily manufactured and installed. While they add components to the system, their simple geometry and material requirements keep the overall complexity increase minimal compared to the significant improvement in structural stability they provide.
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 configuration effectively minimizes deflection and vibration of battery modules, enhancing the stability and efficiency of the battery pack by distributing weight evenly and reducing physical expansion-related resistance.
Implementation Method 1
The at least one supporting block may include an elastic member that is elastically deformable in a direction normal to the first direction
Implementation Method 2
The at least one supporting block may be compressed in the battery pack, the at least one supporting block having a length, when uncompressed, that is larger than that of the space
