American lithium-ion battery producer EnerDel announced Tuesday that it is partnering with the real estate arm of Japan’s industrial trading giant, Itochu Corporation (ITOCF.PK), to develop and produce the advanced battery systems for a residential smart grid energy storage project to be installed in a major apartment building near Tokyo. Such systems would create a secondary market for electric vehicle batteries that still have useful lifespans. They battery system will provide storage for excess grid power and provide power for high-speed charging of electric vehicles on the property.
We are delighted to be partnering again with Itochu to develop this industry leading project," added Charles Gassenheimer, Chairman and CEO of EnerDel parent company, Ener1 (Nasdaq: HEV). "We are pushing hard to drive pioneering initiatives like this to develop a secondary market for automotive grade lithium-ion batteries. I believe this secondary market will be a key enabler to reducing battery costs for automotive buyers and accelerating the growth of the market for electric powered vehicles."
Sales in the five-story building begin this month, with the first move-ins scheduled for early 2011. Going forward, Itochu Property Development, Ltd. aims to introduce the ‘secondary use’ system to 20% of its new apartment buildings. Secondary use implies a battery that has been redeployed from its primary application, normally an electric vehicle, with significant storage capacity remaining. The residual life in that battery can then be sold into a secondary market application, such as community or residential grid storage. Importantly, a viable battery aftermarket could lower upfront costs for automotive buyers given that the cost of the battery can be spread over its useful life. Analysts predict that over time this secondary market opportunity for lithium-ion batteries could be two to three times the size of the automotive market opportunity, the companies said.
"These are the first projects anywhere in the world to bring all the
critical elements of a smart, sustainable network that connects
renewable energy and transportation in the places where people live and
work," said Naoki Ota, Chief Operating Officer for EnerDel. "It will
also demonstrate that EnerDel’s lithium-ion battery systems are equally
capable, whether it is in a car or a stationary grid application."
This is the second such venture between the two companies, following
the announcement last month that they are teaming up with Mazda Motor
Corporation (MZDAF.PK) on a similar system using
vehicles converted to electric drive using a platform designed and
built by EnerDel and its partner Think, which will be stationed at a
Family Mart convenience store.
The two projects will also gather a continuous stream of long-term performance data on new, stationary battery systems in real time, showcasing system longevity and demonstrating the valuable second life on the grid once battery packs have cycled through their automotive lifecycle, where operating parameters are much more taxing.
Itochu is EnerDel’s official sales and marketing partner in Japan, and has been a significant investor in parent company Ener1, Inc. since 2003. In July, EnerDel and ITOCHU joined with longtime EnerDel customer THINK to convert electric drive delivery trucks for Japan’s postal service.
