The turnkey advantage of testing batteries at SwRI
We offer turnkey testing and research services for battery cell, module and pack levels. SwRI can perform all battery mechanical, electrical, thermal and performance testing in-house at a single location. Analysis and testing include, among other services:
- Gaseous and particulate emissions measurement and characterization
- Nondestructive and destructive post-test analysis
- Teardown analysis
- Lithium-Ion battery testing
Testing is performed under an ISO 9001-certified quality management system, with most tests covered under an ISO 17025 testing laboratory accreditation. Disposal of any hazardous waste follows ISO 14001.
Battery Abuse Testing
The ESTC performs rigorous battery abuse testing and analyzes how batteries, cells and packs respond. This allows manufacturers and consumers to better understand how, when and why failure can occur.
- Nail penetration
Battery Safety Testing
We have dedicated engineering staff capable of designing custom battery safety testing plans, enclosures and stands. In addition to standardized battery safety testing, we commonly create custom testing plans and testing rigs.
- Extreme conditions: –70°C to +175°C
- Altitude simulation up to 32,000 m
- Fire resistance and flammability
- Corrosive salt fog and dust
- Thermal runaway prevention
Battery Fire Testing
We help clients characterize thermal properties of batteries through electrical safety validation and battery fire testing.
- External short circuit
- Overcharge and over-discharge up to 1200 V and 1333 amps
- Dielectric voltage withstand
- Isolation resistance
