Following months of rigorous testing and evaluation, CODA’s energy storage system, the CODA Core, has received ‘subject 1973’ safety standards certification from UL (Underwriters Laboratories). UL 1973 is the definitive third-party evaluation of energy storage safety, reliability and performance. The CODA 40 kWh high-voltage system is the first commercial scale energy storage system specifically targeted for behind-the-meter use to be subjected to UL 1973 and pass.
While inverters coupled to energy storage systems are often certified to UL 1741, few manufacturers have subjected complete energy storage systems to UL 1973 testing at the system level. This discrepancy often delays the local permitting and utility interconnection process, and represents a significant barrier to energy storage deployment.
UL 1973 certification of the complete system will reduce installation periods for CODA’s system from weeks to hours. As the industry matures, it is likely UL 1973 will become the litmus test adopted by permitting authorities and regulatory bodies with jurisdiction over energy storage.
“UL 1973 certification transforms energy storage from a nascent technology into a safe, plug-and-play appliance,” said Pete Nortman, COO, CODA Energy. “This independent verification by UL should instill confidence in our channel partners and customers about the safety, quality and reliability of our battery system.”
All primary components of CODA’s scalable system have now been independently verified including battery cells (UL 1642), inverters (UL 1741) and software (UL 1998).
The tests conducted by UL validated the CODA Core’s “ability to safely withstand simulated abuse conditions” well beyond the limits of normal use. For example, one element of the test included “soaking” an energized tower for 12 hours at 150 degrees Fahrenheit. Another test involved dropping an energized battery module from a height of three meters. The CODA Core continued to operate safely throughout these and other tests.
The CODA Core combines advanced lithium-ion batteries (LiFePO4) with inverters, battery management software and an optional environmental management system for harsh climates. CODA Energy’s onboard energy operating software is programmed to meet the application-specific needs of the end-user, be it demand management, time-of-use shifting, back-up power, emergency power, renewables based electric vehicle (EV) charging or other more complex applications.
