At Nissan’s Oppama plant close to Tokyo, there are greater than 700 automated guided autos, or AGVs, which ship elements to staff in a automotive manufacturing unit. Nissan, together with 4R Energy, is now repurposing used EV batteries, which now not have sufficient capability to supply ample EV vary, to energy its AGVs.
The primary-generation LEAF was fitted with a 24 kWh battery pack made up of 48 modules. About eight years in the past, Nissan engineers discovered a approach to take three of those modules, repackage them, and match them inside an AGV. Final 12 months, they started utilizing repurposed battery modules, as a substitute of recent ones, to energy AGVs.
Nissan says lithium-ion batteries, new or repurposed, cost sooner than lead-acid batteries. The AGVs recharge by stopping momentarily at a charging station alongside their route and incrementally prime up at every passing.
Whereas lead-acid batteries had been sometimes changed yearly or two, the repurposed LEAF batteries are anticipated to final seven to eight years.
“Our clients profit too,” mentioned Nissan’s Masashi Matsumoto. “When used EV batteries develop into extra invaluable, trade-in costs rise.”
