Nissan is using old Leaf batteries in portable power packs developed with electronics maker JVCKenwood and 4R Energy, a company owned by Nissan and Sumitomo, which works on power storage systems. Most recently, in Melilla, a Spanish enclave in North Africa, Nissan and Enel installed 48 used Leaf batteries and 30 new battery packs as backup energy storage to prevent power supply interruption. Old Nissan batteries also power Automated Guided Vehicles (AGV) in a car factory in Oppama, Japan. Nissan signed an agreement with the University of Santa Catarina in Brazil in 2018 to explore the potential use of Leaf batteries as part of energy storage solutions. In the Netherlands, the Amsterdam Arena is powered by Leaf batteries with a 2.8 MWh battery storage system.
