UL issues world’s first certification for repurposed EV batteries to Nissan/Sumitomo JV

UL announced that 4R Energy Corporation, a joint venture of Nissan Motors and Sumitomo Corporation focusing on the effective reuse of EV batteries for energy storage systems, is the first organization worldwide to be certified to UL 1974, the Standard for Evaluation for Repurposing Batteries.

Outlining how to sort and grade battery packs, modules and cells that were originally made for electric vehicles (EV) and other applications, UL 1974 helps identify a battery’s state-of-health and introduces ratings to determine the viability for their continued use.

Through this process, performance-validated “second-life” batteries can be utilized for energy storage systems to provide a safe, reliable, clean energy source.
