The certification proves the reliability and safety of the processes that 4R Energy uses in sorting, grade packing batteries, modules and cells of EV batteries to come up with energy storage systems for a safe, reliable and clean energy source.
Eiji Makino, president of 4R Energy, said, “Repurposed EV battery safety and reliability have always been top priorities for our company since we were established in 2010. With UL 1974, our production process has now been certified by one of the world’s leading independent, third-party testing and certification organisations. We are very excited about this milestone, as it helps build customer trust concerning the viability of second-life batteries, and will contribute to the further growth of energy storage systems.”
Jeff Smidt, general manager of UL’s Energy and Power Technologies division added, “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.”
UL first published the UL 1974 standard for EV batteries reuse for the US and Canadian markets in October 2018. The development of the standard is in anticipation of the role reusing EV batteries can play in accelerating the energy transition and the adoption of renewable energy resources.
