Why This Standard Matters
As the new energy vehicle and energy storage industries continue to grow, battery thermal safety has become a key focus across the industry.
In battery packs, thermal insulation sheets are commonly used between cells to help slow heat transfer, reduce thermal propagation risks, and support safer system design during potential thermal runaway scenarios.
Before the release of GB/T 47613-2026, the industry lacked a unified test method for evaluating the thermal protective performance of battery insulation sheets. This made it difficult to compare different materials, verify product performance, and support consistent quality acceptance.
What Does GB/T 47613-2026 Evaluate?
GB/T 47613-2026 provides a standardized test method for evaluating the thermal protective performance of insulation sheets used in power battery and energy storage battery packs. The standard specifies key requirements including test principle, apparatus, specimens, conditions, procedures, result expression, and report contents.

Key Area |
Description |
|
Test Principle |
Simulates thermal protection behavior under single-cell thermal runaway conditions |
|
Test Apparatus |
Includes hot plate, cold plate, temperature measurement, insulation plate, and pressure loading system |
|
Test Specimens |
Applies to thermal insulation sheets used between battery cells |
|
Test Conditions |
Evaluates performance under rapid heating and pressure loading |
|
Test Results |
Uses cold plate temperature data to characterize thermal protective performance |
Two Test Methods Included
|
Method |
Description |
Result Expression |
|
Method A |
Constant Hot Plate Temperature Method |
Cold plate temperature at a specified time point |
|
Method B |
Decreasing Hot Plate Temperature Method |
Maximum cold plate temperature |
By recording the temperature rise curve of the cold plate, the thermal protective performance of the insulation sheet can be evaluated in a more consistent and comparable way. This supports material development, product validation, batch inspection, and supplier evaluation.
