Akihabara News (Tokyo) — Car manufacturer Nissan Motor, in partnership with electronics company JVC Kenwood and the Nissan-Sumitomo joint venture 4R Energy, has showcased a prototype portable power supply created from a used battery of a Nissan Leaf Electric Vehicle (EV).
The initiative to recycle EV batteries is part of Nissan’s commitment to the United Nations’ “Race to Zero Campaign,” which Nissan joined in August.
The 4R Energy joint venture was established in 2010 to produce in-vehicle battery systems with the hope of promoting carbon neutrality via EVs. The company has also worked to develop end-of-life solutions for EV batteries, making them an important contributor to its portable power supply project.
The company announced in 2019 that it had obtained third-party certification from leading safety company Underwriter Laboratories to repurpose batteries and to assess second-life applications for them. Aside from being the first organization in the world to receive such certification, 4R Energy previously experimented with powering streetlights with used EV batteries in Namie town, Fukushima Prefecture.
The goal of the collaboration is keep EV batteries from exiting the reduce-reuse-recycle system, which would otherwise leave them uselessly corroding in landfills or contributing to carbon emissions during incineration.
