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.”

    What a bad joke. Fact is it’ll cost more to find, buy used packs and do this testing, etc than it costs to make them new!!
    I do Volt module sales for a living partly and no way can they do this economically.
    Now the way is selling inverter kits that turn packs people have, buy, into Powerwall type storage by simply plugging it into the pack and a 240vac outlet, is a viable business model.

      It doesn’t have to be profitable. It just has to offset part or all of the disposal costs. I certainly hope that countries will require manufacturers to dispose of their own battery packs.

        Sorry but the company would strongly disagree with you.
        I agree that ALL batteries, metals should be recycled by law like lead already is and a great success story. Most lead batteries are on their 12th recycle by now.

          The company would hate it!!! With a lobbyist’s passion. In the pulp and paper industry there was total resistance to any regulation on their wastes. But bit by bit rules were brought it to regulate their solids, liquids and air emissions. Wastewood was turned into wood pellets. Offcuts became engineered wood beams. Saw dust became pressboard. Waste water treatment sludge became fertilizer. Boilers became part of an integrated cogen facility. Resin acids are refined into turpentine.

          Don’t underestimate industry ingenuity when it comes to turning lemons into lemonade

            This isn’t Nissan but another company that has to
            profit to survive..
            Nor does Nissan own the packs. They belong to the EV owners so just where do they get cost effective packs?
            Not from a junk yard as we EV and storage people are buying them up at prices above OEM to build.
            I understand recycling industry well as I recycle EV packs for a living though I do Volt packs as 3x better than Leaf’s modules in performance, life.
