As EV and Energy Storage System (ESS) projects continue to expand in the U.S. market, battery pack protection materials are being evaluated beyond basic cushioning performance. Engineers are increasingly focusing on dimensional stability, compression recovery behavior, and long-term aging performance under real operating conditions.
For Battery Pack Cushioning applications, materials are expected to provide more than impact absorption. They must also maintain structural support during transportation, assembly, and long-term operation.
Why Thermal Shrinkage Is Becoming a Key Consideration
Battery systems often operate under changing temperature conditions.
Typical EV scenarios
Heat accumulation during fast charging
High-temperature parking environments
Temperature rise inside enclosed battery structures
Typical ESS scenarios
Outdoor container energy storage systems
Long-duration operation
Regional temperature fluctuations
When cushioning materials experience shrinkage or deformation under heat exposure, several issues may occur:
Changes in cell spacing
Reduced internal support
Battery movement during transportation
Reduced cushioning performance after long-term compression
As a result, thermal dimensional stability is becoming an important factor in Battery Protection Material selection.
How EVA Foam Performs Under Thermal Conditions
Based on current material data, Black EVA Foam shows defined performance boundaries:
Key specifications
Softening begins at 65°C
Shrinkage begins at 90°C
Aging may begin after approximately 3 years above 40°C
Compression set at 85°C: 48–51%
Compression set at room temperature can be as low as 11%
These figures indicate that EVA Foam is suitable for cushioning, vibration control, and spacing applications rather than continuous high-temperature insulation.
For Battery Accessories EVA Foam Pad applications, engineers typically evaluate:
Operating temperature
Compression load
Cell arrangement structure
Product lifecycle requirements
How to Select Battery Pack Cushion Materials
Evaluate compression recovery
Compression Set helps assess how well a material maintains support after long-term loading.
Lower compression set values generally indicate more stable structural performance.

U.S. EV Battery Pack Connection Strip Breakage Draws Attention as Tensile Testing Becomes a Structural Evaluation Refere
2026-05-21
Industry Background: Battery Pack Structures Face Increasing Mechanical Demands
As EV and energy storage applications continue expanding across the U.S. market, engineers are placing greater emphasis on the mechanical behavior of battery pack structural components. Traditionally, purchasing and design teams focused on conductivity, dimensions, and welding compatibility. Today, structural performance during assembly and operation is becoming another selection factor.
In EV battery pack and power battery module applications, a battery pack steel strip serves more than an electrical connection function. In many assemblies, it also contributes to load transfer and structural connection. Under automated production, transportation vibration, and high-load operating environments, the interaction between tensile force and structural movement becomes increasingly relevant.
Why Is Battery Connection Strip Failure Receiving More Attention?
Assembly Conditions Are Becoming More Complex
As battery manufacturers increase automation levels, module designs continue moving toward higher integration. During spot welding, bending, positioning, and assembly operations, connection strips may experience additional mechanical loading.
Common engineering search terms include:
battery strip breaking problem
battery strip failure during assembly
battery strip tensile strength
These searches do not necessarily indicate widespread product failure. Instead, they suggest that engineers increasingly want to evaluate structural risks earlier in the selection process.
In real-world projects, dimensional tolerances, connection geometry, weld layout, and assembly methods can all influence mechanical behavior under load conditions.
Why Tensile Testing Is Becoming Part of Supplier Evaluation
Data Is Increasingly Used in Structural Assessment
Instead of relying solely on material names or appearance specifications, engineering teams increasingly use measured test data during component evaluation.
According to the uploaded tensile test report, five samples were tested under a tensile speed of 2 mm/min, with recorded maximum breaking force values ranging from:
Maximum value: 53,108 N
Minimum value: 43,110 N
Average value: approximately 48.8 kN
The test environment was conducted at 34.4°C and 61% RH.
These values represent measured performance under specified laboratory conditions and should be used as reference data for structural evaluation rather than direct indicators of long-term field performance.
How Engineers Are Adjusting Selection Criteria
Mechanical Data Is Becoming a Selection Factor
For U.S. EV and energy storage projects, supplier evaluation is gradually moving beyond material type and thickness alone.
Engineering teams are increasingly considering:
Mechanical Load Data
Measured breaking force values may help provide a clearer understanding of structural load behavior during assembly and operation.
Welding Compatibility
Spot welding consistency and connection performance remain important considerations in battery module production.
Assembly Consistency
As automation levels increase, dimensional stability and repeatability continue to receive attention.
Structural Load Conditions
Mechanical testing data can provide additional reference points when evaluating components intended for complex assembly environments.
As battery systems become more integrated, measured structural performance data is becoming part of engineering discussions and supplier selection processes.
