Nexceris to present Li-Ion battery safety monitoring solutions at upcoming NAATBatt 2016 Energy Storage Innovation Summit on February 29 – March 3
Engineers at Nexceris, LLC have developed breakthrough technology for ensuring safety of lithium ion batteries in stationary and maritime power applications. This technology is being applied to advanced monitoring solutions that can work independently or in concert with existing battery management systems. Once completed, the products will be available for installation to prevent or limit property and health damages due to battery failure.
Nexceris has been contracted by the U.S. Navy to develop monitoring systems for ship use. As Li-ion batteries are deployed more on naval vessels, ensuring safe operation is paramount. According to Steve Cummings, Nexceris’ chief investigator on the project, “we have demonstrated some exciting new ways to detect off gassing events in battery systems which precede catastrophic failure such as thermal runaway. This new approach could help improve the safety of lithium ion battery systems in the future.”
The technology, developed jointly under DOE ARPA-E and Navy SBIR funding, detects the presence of flammable electrolyte that can be released due to puncture, manufacturing defect, or loss of integrity during operation. The sensors can detect issues in distressed batteries two to seven minutes sooner than can be detected with traditional battery monitoring solutions. This may give time for shut down prior to any catastrophic failure.
