4R Energy earns first UL 1974 battery reuse certification

4R Energy, a joint venture between Nissan and Sumitomo that focuses on EV battery reuse, will be the first group certified to the UL 1974 Standard for Evaluation for Repurposing Batteries.

UL 1974 outlines how to sort and grade EV battery packs, modules, and cells, identifying state-of-health and determining viability for second-life use as storage.

UL 1974 was published in October 2018 as a bi-national Standard of the US and Canada. 

Eiji Makino, President of 4R Energy, said, “With UL 1974, our production process has now been certified by one of the world’s leading independent third-party testing and certification organizations. This milestone…helps build customer trust concerning the viability of second-life batteries and will contribute to the further growth of energy storage systems.”

Jeff Smidt, VP and GM of UL’s Energy and Power Technologies division, said, “We are pleased to issue our first UL 1974 certification to 4R Energy and help accelerate the application of recycled and repurposed batteries both as a backup energy source and storage for energy generated by clean, sustainable sources.”
