Nissan EV Batteries Reused At French Data Center

July 2nd, 2016 by  

Nissan EV batteries that were no longer suitable for vehicles have found another life as stationary energy storage at a data center in France. Saint-Romain de Colbosc Eco Park is the site of the Webaxys data center. Nissan collaborated with Eaton, a power management company, to create the energy storage system.

147582_10_5“This installation at Webaxys marks an important historical moment for data centres in their quest to become energy autonomous in the near future. By combining Nissan’s expertise in vehicle design and reliable battery technology with Eaton’s leadership in power quality and electronics, we hope to demonstrate that data centre energy management can be stable, sustainable and cost efficient in the near future,” said Gareth Dunsmore, Nissan Europe’s Director of Electric Vehicles.

Webaxys is a webhosting company with locations in Sotteville-lès-Rouen and LeHavre. The company intends to open more data centers using the Nissan/Eaton energy storage technology.

Though technical details about the Saint-Romain de Colbosc Eco Park data center energy storage system are not in the recent Nissan press release, some clues might be gleaned from a 2015 announcement that Nissan and Eaton were beginning to work together.

This source says the Eaton technology Nissan was considering was a 93PM UPS, in combination with not more than 4 reused Nissan Leaf batteries. The system was said to have about 20 kWh available for each battery, so a 4-battery system would obviously have 80 kWh. It also says the cost of the Eaton technology was expected to be about €10,000, and for the batteries, it would be €400 to €500 per kWh.

Nissan EV batteries are also being used within a home energy storage product, and Eaton is again involved.

Over 90,000 employees work for Eaton and the company has its corporate headquarters in Dublin, Ireland. The North American regional headquarters is located in Cleveland, Ohio.

Hello, I have been writing online for some time, and enjoy the outdoors. If you like, you can follow me on Google Plus.

  • “The system was said to have about 20 kWh available for each battery”

    Hmmm. I have a LEAF purchased in Australia in September, 2015 (2012 build). As of now, I have 19,000klms on the clock. LEAF Spy reports “only” 18kWh when fully charged (also at “new”).
    If these are “reused Nissan Leaf batteries” I wonder whether the 20kWh can be right.

    I asked Nissan to sell me those batteries for LEAF range extenders, they said NO. They might have a better reputation if existing owners could get more range.

    This is very good news to see this actually happening as predicted.

    Some new thoughts about used batteries: What remains after the useable first 20% has been depleted? Don’t be hasty with that answer. Some lithium curves are just getting started at 80% of capacity. They are quite the opposite of lead acid. They literally could have 10,000 cycles left.
    This brings me to another puzzle: Tesla 10 kwh powerwall…the one that vanished. Its chemistry was only warrantied for 500 cycles (weekly for 10 years). It was the same chemistry as in the Tesla models S. We all wondered why Tesla offered it to begin with, since the upper limit was thought to be about 1200 cycles and the “other” 7kwh powerwall with manganese had 5000 cycles. Now I think the strange secret might be that the battery actually had tremendous numbers of cycles after 20% depletion (the standard “end of life for batteries” up to now.) Tesla may have cancelled the 10kwh powerwall because the post 80% lifespan was far too long. If you see Jeff Dahn’s slide show claiming 20,000 cycles between 80% and 60% for a “similar, but not identical chemistry” from Metronic, then it is possible that Tesla didn’t want to publicize that fortuitous second life of battery packs. Speculation? Yes.
