Sumitomo lays claim to developing and installing the world's first large-scale power storage system.
Nissan Worker Assembles LEAF Battery in Tennessee - 16 Used Batteries Provide Energy Storage For Sumitomo's Unit
The energy storage system makes use of reclaimed Nissan LEAF battery packs. In total, 16 LEAF packs our housed in Sumitomo's energy storage unit.
Constructed on Yume-shima Island in Osaka prefecture Japan, the system will immediately be put into operation.
As Sumitomo states:
"Sumitomo Corporation created the joint venture company, “4R Energy Corporation”, in collaboration with Nissan Motor Co., Ltd. in September 2010, to address the secondary use of EV lithium-ion batteries. The used EV batteries that will be recycled into this large-scale storage system have been recovered and have gone through thorough inspection and maintenance at 4R, to confirm safety and performance. This prototype system (600kW/400kWh) consists of sixteen used EV batteries."
How will this energy storage system be utilized? Here's what Sumitomo says:
"Over the next three years, the system will measure the smoothing effect of energy output fluctuation from the nearby “Hikari-no-mori,” solar farm, and will aim to establish a large-scale power storage technology by safely and effectively utilizing the huge quantities of discarded used EV batteries which will become available in the future."
Energy storage, it seems, is where used EV batteries will go in the near future to
die start a new life.
