First large-scale power storage system from reused EV batteries
completed in Japan

Wondering what will happen to all the used electric vehicle batteries in
the future? Pioneering the way is Tokyo-based Sumitomo Corporation,
which has developed and installed the world’s first large-scale power
storage system utilizing used EV batteries.
The prototype system, of 600kW/400kWh capacity consists of sixteen used
EV batteries, and is built on Yume-shima Island, Osaka, where it begins
operating this month.
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 to
safely and effectively utilize the huge quantities of discarded used EV
batteries that will become available in the future. This project has
been selected as a model project for “Verification of the battery
storage control to promote renewable energy” for the fiscal year 2013 by
the Ministry of the Environment of Japan.
Sumitomo Corporation, in collaboration with Nissan Motor Co., Ltd.,
created the joint venture company, 4R Energy Corporation, in September
2010, to address the secondary use of EV lithium-ion batteries. The used
EV batteries that are recycled undergo thorough inspection and
maintenance at 4R, to confirm their safety and performance.
“We are pleased to be a part of such an important verification project
that can both utilize used EV batteries, and provide a large-scale power
storage facility, which are important issues that need to be addressed
for the future of renewable energy,” commented Norihiko Nonaka, general
manager of Sumitomo’s Battery Business Development Department.
Sumitomo is seeking new business opportunities that can make use of this
economical storage system, as well as working on the development of new
applications for used EV batteries.
