Battery Testing

Stress Engineering Services, Inc. (SES) offers battery safety and performance testing to various industry standards and has facilitated the development of standards by which batteries are tested. We provide expert battery testing services for clients across several applications and industries, including: Aerospace; Automotive; Grid Storage; Transportation; Aviation; Oil and Gas; Maritime; Medical; and Consumer Electronics.

Battery Testing Services

Our Battery Testing Services dig deep into the complex electrochemical/thermal system that constitutes a Lithium-ion Battery to provide answers to critical questions shared by both battery engineers and end users alike, including:

Which factors have the greatest influence on the probability and severity of a thermal runaway event?
How can thermal runaway propagation be mitigated using safety-focused module design?
What steps can be taken to improve the safety of LIBs during operation and transportation?

Thermal runaway propagation testing, containment testing, standards development testing, cycle life and performance testing and fire exposure resistance testing are all performed at our Testing Facility in Waller, Texas. This state-of-the-art test facility houses a wide array of equipment used to characterize the cells electrically, along with various chambers for environmental control, abuse testing, external fire testing, and gas analysis.
