4R Energy Corporation, a subsidiary of Nissan Motor and Sumitomo and leader in second-life batteries, and Relectrify, a battery control technology specialist, announced today the commencement of a collaboration to develop second-life battery storage solutions. The products in development include repurposed used batteries from the Nissan Leaf, one of the world’s best-selling electric vehicles, using Relectrify’s battery and inverter control technology, to allow 4R Energy to address significant opportunities in the storage market.

“We are actively seeking to build affordable, fully-integrated battery systems”, said Eiji Makino, President of 4R Energy. “Used electric vehicle batteries offer a significant opportunity to create compelling energy storage systems in Japan and beyond. Relectrify’s technology holds the key to achieving capable, long-lived storage in a cost-effective manner.”

4R Energy brings a strong track record as a provider of residential storage systems based on new batteries to customers in Japan. The company has also demonstrated repurposing used electric vehicle batteries at industrial scale. Earlier this year, 4R Energy opened a facility in Namie, Japan to repurpose used electric vehicle batteries for a second life both in and out of the vehicle.

“Relectrify’s goal is making energy storage affordable”, said Valentin Muenzel, Co-Founder and CEO of Relectrify. “We are excited to work with 4R Energy to leverage our advanced control technology to deliver compelling battery storage products to its customers.”
