Nissan announced the largest second life battery storage and vehicle-to-grid project ever, with Enel and Eaton as partners.

The Japanese company intends to equip its new regional office in France with 100 vehicle-to-grid bi-directional chargers (CHAdeMO) supplied by Enel,  with a energy storage system combining 64 LEAF packs installed by Eaton.

ESS will be rated for about ~1 MWh energy (64 x 24 kWh would mean 1.5 MWh if they were new, so these packs each have approximately 67% of original capacity.).

There is also idea to do similar project in other markets.

“As the pioneers of the Nissan LEAF, the world’s best-selling 100% electric car, today’s announcement is representative of Nissan’s commitment to pushing its expertise in EV and battery production to the next level. The company is developing an ecosystem of technologies that work seamlessly together to create sustainable and efficient solutions for the future.

It also marks an important step in the company’s plans to make its Intelligent Mobility vision a reality in Europe. The integration of this technology is a clear demonstration of how cars in the future can be connected to social infrastructure such as road, information and electric power networks, and brings to life the vision’s third pillar – Intelligent Integration.”

With 1 MWh of energy in ESS, and up to an additional 1-2 MWh in cars connected on the parking lot (100 LEAFs with 24 or 30 kWh) it will be decent energy storage for sure.

Nissan hopes to draw energy at off-peak and then use it during the day.

“The new building will feature 100 vehicle-to-grid chargers, from Nissan’s partner ENEL, allowing Nissan’s range of EVs to plug in and draw down energy from the grid at off-peak periods with the ability to “sell back” the stored energy to the grid. It will also feature a 1 MWh energy storage system, from Nissan’s partner EATON, the battery storage experts, powered by 64 Nissan LEAF second life EV batteries combined with solar energy generation.

The company hopes to extend this innovative battery technology to other major Nissan sites and facilities around the world over the next few years. The systems which will be installed at Nissan’s new French office will serve as a live test case of what can be achieved when electric cars are used to their full potential.”

“By reducing grid dependency and using excess energy stored in EV batteries in a smart way, Nissan believes today’s announcement will be a game-changer in the way people and businesses utilise electric vehicle fleets.

The new technology is expected to slash energy costs at the new France office by reducing drawdown of energy during peak periods in favour of off-peak tariffs. The new energy management system will also decrease the amount of contracted power consumed from the local electricity supplier.”

Paul Willcox, Chairman, Nissan Europe, said:

“At Nissan, we’re going beyond product. Innovation is about more than creating something new. It’s about making something better and finding solutions for the future.

“Nissan’s electric vehicle batteries extend our expertise beyond production to finding new and innovative ways to store and transfer energy.

“By demonstrating that electric vehicles can play an integral part in the energy management systems of the future, this project is a watershed moment on our journey towards a fully electric future.”

Some solar PV inverter maker needs to build an inverter & battery charge controller that is designed to work with any of the batteries from any of the current cars with decent sized batteries (Volt, LEAF, Tesla, iMiEV, FFE, Fiat 500e, Think City, Coda, etc.)


V2G works with DCFC port (Chademo + CCS). That would exclude Volt, FFE, 500e, … unless they have major hack job done on them. Now the question is, would quickcharge power expand their JdeMo to include these other cars as well as allowing V2G?

Well, I’m talking about supporting old batteries that get removed from old EVs. Give the old EV batteries a new life as a home battery.

spec, especially the Volt which is the low cost readily available one.
The others are more expensive or hard to
Big packs like the article says will be hard because people own the packs in the US.
Only a battery lease, swapping does one own a lot of packs.
But they could just hook it up to the solar panels of the correct voltage directly with a high and low voltage shut off and run the inverter from that voltage.
You can also with an upper voltage limit, directly charge an EV through the DC charge port.

Hmmmm! Interesting.

Not sure I would go along with my employer drawing down my battery for reduced electricity rates, then having me charge it back up at higher rates to get back home or whenever!

Just how does this work in practice?

They speak of using battery charge/discharge “in a smart way”.
One man’s smart can be another man’s out-of-pocket expense.

Well, if it’s instead used to couple with solar parking lots, then the system would chop the top off peak power production around noon, and re-distribute it in the afternoon.

So, there are at last 64 “bad” LEAF packs already? =)

I was wondering if there are significant numbers (1000+) of retired LEAF battery packs around yet?
Anyone have data on this?

In Europe they lease the packs so the EV company owns them. It won’t work in the US as the EV owner owns them.
You’ll have to buy them from wrecking yards.

Even in EU, most are sold – only a very few customers + some fleet sales go for renting battery pack.

I would suppose this specific project is all being done with support from the utilities but I would think that in general utilities are not that thrilled for us to be buying off peak cheap energy, storing it in batteries and then using during peak hours.

Endless supply with all those leafs with battery degradation.

Got data to back that up Jychevyvolt??

I guess he does not.
I concur with you, Bob; thaere have bern darn few battery failures.

In Europe three batterys has been changed from 50.000 Leafs. I never get above 85°F here, most time battery is between 50-70°F, so battery problems from Leaf are only in very hot climates.

I asked Nissan to sell me battery modules for a LEAF range extender, they said absolutely no. Extending range to 120 miles in 24 kWh LEAF cars would do more to improve their image.
