Energy Storage Solution Built From Recycled “Full Pack” Nissan LEAF Batteries Shown Off

Nissan and Eaton equip new eco-designed Webaxys data centre with first deployment of energy storage solution

Nissan and Eaton team up for a larger application of energy storage via used LEAF batteries

Nissan is ever moving forward with its commercialization of energy storage systems using ‘second-life’ lithium-ion batteries from electric cars.

The company’s most recent large-scale installation of re-purposed EV batteries power Webaxys’ data center at the Saint-Romain de Colbosc Eco Park in Normandy, France.

As you can see in the photo, Nissan is using battery pack set upright (not unlike BMW’s recent ESS solution) and enclosed in an external closet beside Eaton power electronics.

Also of note: Smaller residential ESS projects are also available through Nissan’s xStorage program in Europe  – €4,000 ($4,5000 USD) nets customers a recycled 4.5 kWh battery back-up system installed (details).

Webaxys plans more such installations in other regional data centers in the future “that harness this same technology and integrate into the local economy, minimising environmental impact and energy consumption“.

“Nissan and Eaton have joined forces to provide an innovative energy storage solution incorporating renewable energy sources for cloud and IT services hosting company Webaxys’ new, ‘eco-responsible’ data centre based at the Saint-Romain de Colbosc Eco Park in Normandy.

The energy storage solution provides a ‘second-life’ for Nissan electric vehicle batteries and in combination with Eaton’s leading uninterruptible power supply capabilities, provides an industrialised energy control and storage solution for managing data centres. This innovative solution not only enables integration with local renewable sources, but allows companies to draw down from and provide energy back to the grid, ensuring stable and cost efficient energy management systems.

Data centres already make up 1.5% to 2% of worldwide electricity consumption, and this rises sharply each year. However, the energy demands of data centres, which cannot tolerate the slightest power outage, makes the application of renewable energy sources particularly difficult. This new Eaton and Nissan energy control and storage system will mean firms like Webaxys can store energy once produced so that it can be used on demand to power the business. This overcomes risks associated with renewable energy sources which are more susceptible to interruptions in supply and ensures the supply of pure, quality power.”

Gareth Dunsmore, Director of Electric Vehicles, Nissan Europe said:

“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.”

I’ve always wondered where the re-purposed packs come from.

Reman’d packs?
LEAF’s cosmetically trashed?
Bought back LEAF’s?

A very green solution could be to upgrade/”recycle” the existing Leaf fleet by selling higher capacity batteries to Leaf owners and take back the old batteries for storage projects.

But I am dreaming, there is no evidence that this is going to happen.

Heat stressed Leaf batteries, that’s exactly what I want hanging on my wall. 😉

Why not?

I guess you missed it. Key phrase was, “Heat Stressed”.

Heat prematurely ages the chemistry in lithium batteries. Nissan didn’t see fit to use a liquid cooling system for its Leaf Batteries– which upset some customers who lost significant range due to thermal damage to their cars. Arizona, SoCal and Texas owners come to mind, but I’m sure there were others.

Do I want prematurely aged batteries from recycled Leafs to help power my house, out of all the other options available to me as a homeowner?

Probably not. Would you?

Would I?

That depends. It all comes down to cost per watt. Even if the cells are slightly degraded, they still have usable capacity.

As long as the price per watt is cheaper than the “other options”, absolutely.

Nissan and BMW clearly focus on 2nd hand battery usage. However Tesla seems to focus on direct recycling. With the current learning curve in batteries this makes more sense to me. What do you guys think?

How Can Nissan claim to be super at battery tech AND have a lot of discarded batteries at hand?

Because they build a lot of cars?

Nissan has shipped over 200k Nissan LEAFs worldwide, over the last 5+ years.

If only 1% of those have replaced packs or were salvaged after a crash or whatnot, that’s ~ 50 MWh of storage energy.

Over a 10 year span, the vast majority of those packs will degrade to the point that they are worth replacing. Maybe Nissan has a newer pack and these old packs can be picked up for a song (“core” fee). Getting ready for that now is wise.

New or used it will eventually need to be recycled. Larry

a Dollar/Wh recycled?
on the steep side, MHO.
