Results of the testing demonstrated that Exro's Cell Driver™ significantly surpassed the industry's UL9540A requirements.
CALGARY — Exro Technologies Inc., a clean technology company that has developed power control electronics that try and expand the capabilities of electric motors and batteries, announces that the company’s Cell Driver™ Energy Storage System has successfully completed large-scale module fire testing and the first major phase towards product certification from Underwriters Laboratories. UL certification is globally recognized as the gold standard in product safety testing for energy storage, with certification required for all energy storage systems prior to connecting to the grid in North America. The tests were conducted by ESRG Lab, industry leaders in product testing, and witnessed by Intertek, a certification provider to industries worldwide. Results of the testing demonstrated that Exro’s Cell Driver™ significantly surpassed the industry’s UL9540A requirements, considered one of the primary standards for energy storage safety.
Phase One Test Results Point to Cell Driver™ as a Product Leader in Thermal Management
Safety is a major concern and focus for the battery storage industry. While fires are rare, when they do occur, they pose considerable risk given the hazardous and volatile nature of the battery chemicals involved. The UL9540A test is designed to assess an energy storage system’s ability to limit the spread of a potential fire through thermal runaway (i.e., fire propagating from one defective battery cell to others). The test involves applying a heating plate to a battery cell to artificially induce a thermal runaway event whereby the fire would spread to adjacent cells within the module under test and the energy system.
These results reportedly show the safety performance of Exro’s Cell Driver™. More than 10 hours (37,688 seconds) was required to achieve battery module fire propagation as per the UL9540A test plan, a significant amount of time for this test.
“We are absolutely thrilled with the performance of our energy storage system during this important first phase of UL testing, which is widely regarded as the most demanding of the certification requirements,” said Chief Executive Officer Sue Ozdemir. “As the world pushes forward with the electrification transition, Exro’s Cell Driver technology is proving to be a superior and cost-effective product offering that addresses major industry challenges in energy storage from safety, complexity of design, reliability and having a positive impact on the circular economy given a focus on repurposing used EV batteries for a second life in stationary storage. With Global Energy Storage Market Reports forecasting energy storage to be an approximately $100 billion market by 2030, we are looking forward to providing additional visibility into our progress towards commercialization over the coming months, as we work to capture market share in the under-serviced commercial and industrial sectors.”
