In what sounds a lot like a relaunch of the V2G hardware unveiled at the Geneva Motor Show back in March, a Nissan press release yesterday announced under the headline “Power to the People: Nissan and ENEL launch first smart grid trials” that:

  • Electric car to become home ‘energy hub’, allowing renewable energy to be harnessed and stored by the car
  • Nissan will commence Smart Grid trials in partnership with energy supplier, ENEL
  • More than Nissan 200,000 LEAF sold worldwide

At the 21st UN Conference on Climate Change (COP21) in Paris this week, Nissan has announced the development of an innovative Vehicle to Grid system which will allow drivers to operate as individual ‘energy hubs’ with the ability to store, use or return electricity to the grid.

Nissan will commence Smart Grid trials in partnership with multinational energy manufacturer and distributor, ENEL.

As part of the landmark partnership, Nissan and ENEL have committed to working together, to explore:

Introducing this revolutionary technology to the European market;
The extended use of ‘second life’ electric vehicles batteries for static applications;
Designing and evaluating potential affordable energy and mobility pack offers

Vehicle-to-Grid allows customers to take control of the type of energy they consume – avoiding peak tariffs and generating additional household income during peak times.

Here’s how the facelifted hardware looks, with an “Enel” badge instead of the original “Endesa” one:

Nissan and Enel also helpfully provide a couple of infographics to help explain how their “revolutionary technology” will work. Here’s the simple version:

which looks a lot like a less colourful version of the V2G banner at the top of this page! Nissan go on to say that:

Using a special two-way charger and energy management system developed by Nissan in partnership with ENEL, LEAF owners can connect to charge at low-demand, cheap tariff periods, with an option to then use the electricity stored in the vehicle’s battery at home when costs are higher, or even feed back to the grid to generate additional household income.

“Our customers are no strangers to great value, with the Nissan LEAF offering unbeatable value motoring from three cents per kilometre. Now, with the introduction of Smart Grid technologies, we can empower motorists to take control of their energy mix – stimulating greater use of renewable power, and offering significant financial rewards for those who make the switch to electric.

“The personal benefits of innovations like this are clear, but moreover, we believe that this technology could help guarantee a cleaner energy infrastructure for generations to come.”

Nissan – the world leader in EV sales with 200,000 Nissan LEAF sold worldwide – is turning a page in zero emission mobility by unlocking the full potential of its electric vehicle batteries with the ENEL two-way charging technology.

Here’s the other infographic, which shows in more detail how V2G technology might “unlock the full potential of [a Nissan LEAF’s] batteries”. Click on the image to view a larger version:

Another Nissan press release mentions where those “Smart Grid trials” will take place:

The agreement with the ENEL Group will bring the first Grid Integrated Vehicles to countries where regulation allows sufficient value generation. Denmark will host the first set of trials with Germany, Netherlands and other northern European regions following suit. This endeavour is part of Enel’s and Nissan’s commitment to support the entire electric vehicle ecosystem, going way beyond the car itself and delivering new services to the power industry.

I wonder if they could be persuaded to run one here in the United Kingdom? We are a “northern European region” after all! Here at V2G UK we’re rather keen to try out the techniques hinted at by the small print in the bottom right hand corner of the picture, which reads as follows:

During high peaks where energy is drawn from the grid en masse, electric vehicles can give back power to support the national infrastructure, stabilising the energy drawn collectively by using the car as a personal power station.

Hydrogen Mobility Europe Launched with €32 Million Funding

In a press release earlier today ITM Power announced that:

The most ambitious hydrogen mobility initiatives in Europe have joined forces to support the introduction of hydrogen-fuelled transport

A large coalition of European partners has launched the Hydrogen Mobility Europe project (H2ME). H2ME is co-funded with €32 million from the Fuel Cells and Hydrogen Joint Undertaking (FCH JU). The project will support the deployment of Fuel Cell Electric Vehicles (FCEVs) and Hydrogen Refuelling Stations (HRS) across Europe.

ITM’s headline summed things up so perfectly that we’ve unashamedly plagiarised it! The Hydrogen Mobility Europe project web site still says “Full website launching soon” at the top, but does state that:

The project brings together Europe’s four most ambitious national initiatives on hydrogen mobility (in Germany, France, Scandinavia and the UK) and will:

  • Place 200 fuel cell cars (from Daimler and Hyundai) and 125 fuel cell range-extended vans (Symbio FCell collaborating with Renault) in customer hands
  • Deploy 29 state-of-the art-hydrogen stations
  • Carry out a long-term evaluation campaign to demonstrate the readiness of the technology for a mass market
  • Develop insights into the customer experience and practical challenges of rolling out the technology at a large scale, which can be used in optimising the technology during its commercial roll-out

It also includes a link to their own press release, which adds that:

H2ME is the largest European project of this nature and is based around an alliance of the four most ambitious hydrogen mobility initiatives in Europe: H2 MOBILITY Deutschland, Mobilité Hydrogène France, Scandinavian Hydrogen Highway Partnership and UK H2 Mobility.

These initiatives originally brought together the key stakeholders in the hydrogen sector (vehicle manufacturers, hydrogen refuelling station providers and Government representatives), to study and develop strategies to make hydrogen-fuelled transport a reality in the respective regions. These initiatives will now be working together to make hydrogen-fuelled transport a reality in Europe.

Under H2ME they will deploy 200 FCEVs, 125 fuel cell range-extended electric (FC RE-EVs) commercial vans and 29 new HRSs in 10 countries (Austria, Belgium, Denmark, France, Germany, Iceland, Netherlands, Norway, Sweden and the UK) by 2019. This plan ties in with existing national level initiatives for the roll-out of a large scale hydrogen refuelling infrastructure, aimed at enabling Europe wide emission-free driving. The consortium, led by Element Energy, includes global leaders in the hydrogen and fuel cell sector, from fuel cells and car manufacturers (Daimler, SymbioFCell, Hyundai, Honda, Intelligent Energy, Nissan) and infrastructure providers (Air Liquide, BOC, H2Logic, ITM Power, Linde, McPhy Energy, OMV, AREVA, EIFER, H2 MOBILITY Deutschland, HYOP, Icelandic New Energy, Communauté d’Agglomération Sarreguemines Confluences) to data monitoring and dissemination organisations (Cenex, WaterstofNet).

The original agreements for the project were signed in July this year and the project has already delivered the first vehicles to customers in France and Germany (Daimler, SymbioFCell).

We have previously reported on BMW’s FCEV technology, developed in conjuction with Toyota, whose names are strangely absent from the above press releases. Perhaps that’s something to do with BMW’s use of “cryogenic pressure vessel technology”? Here’s BMW’s “CCH2 FCEV i8” prototype:

We wondered back in July about the:

Wait to discover how, where and when the hydrogen infrastructure BMW refer to materialises in Europe.

The H2ME project seems to be at least a partial answer to that question. In similar vein see also our report on the UK’s Riversimple open source hydrogen fuel cell vehicle. A much less extravagent beast than either BMW’s prototype FCEV i8, or the production Tesla Model S for that matter!

Nissan GB Announce 30 kWh LEAF

Posted on by

Carlos Ghosn hinted at this during the Nissan annual shareholder’s meeting in Yokohama in June, and it has now come to pass. In a press release yesterday Nissan GB announced:

The introduction of the LEAF 30 kWh – an updated Nissan LEAF that gives drivers 155 miles of motoring range, beating all of its competitors in the segment.

This remarkable achievement – one that opens up a new world of opportunity for drivers – is made possible thanks to the introduction of a new 30kWh battery. The new battery is the highlight of an update package that will see the 2016MY LEAF 30 kWh reinforce its position as the most capable and practical electric vehicle in the world, and with the best value. The longer range significantly broadens the LEAF’s appeal – making it a true alternative to an internal combustion engine vehicle for thousands of motorists and reinforcing its position as the world’s best electric car.

Here’s how the go farther 2016 LEAF looks:

Based on our recent EV road tests it seems extremely unlikely that it will actually average 155 miles per charge in real world driving on British roads. Whilst increased range is of course very welcome, here at V2G UK we’re most interested in the new battery technology that enabled that improvement. On that topic Nissan had this to say:

The LEAF’s new 30kWh battery delivers a longer range with no compromise on internal packaging. Available on Acenta and Tekna trim grades, it has exactly the same exterior dimensions as existing 24kWh unit and only a modest 21 kg increase in weight. The result? A car that goes significantly further while offering the same practicality and usability as previous versions.

Key to the new battery’s higher performance is an update to its internal design and chemistry. The introduction of Carbon, Nitrogen and Magnesium to the electrodes improves performance, while the change to the cell layout also contributes to the gain. Indeed, Nissan is so confident about the performance and reliability of the new 30kWh battery that the capacity will be covered by an eight year, 100,000 mile warranty.

By all means read all about the other new features of the 2016 LEAF, but that last sentence holds the key for us, since it underlines the message we received at a Nissan vehicle-to-grid workshop, also in June of this year:

Nissan’s battery electric vehicle “warranty doesn’t prohibit V2G” and the “impact [of V2G] on the battery is insignificant”.

If like us you’re now wondering “where, when and how much” Nissan GB have this to say:

Sales of the model year 2016 Nissan LEAF 30kW will begin in the UK in December 2015. Priced from £24,490 for the Acenta trim, the LEAF 30kW is available for just £1,600 more than the equivalent LEAF with a 24kW battery.

I don’t know about you, but we can’t wait!

My Electric Avenue Preliminary Results Revealed

Posted on by

Just in case the name is unfamiliar to you, the My Electric Avenue project has been running for a couple of years now. According to the My Electric Avenue web site:

Whilst there’s plenty of capacity to deliver power for EV charging across the UK, if the charging requirements are concentrated in small areas and during peak demand, local feeders can become overloaded. With the development of even faster charging times, this problem shows no signs of fading.

The full size and scale of the problem that EV clusters could cause will only become apparent to Distribution Network Operators (DNOs) when they are already on the network, demanding costly mitigation measures in short timescales.

EA Technology and Scottish and Southern Energy Power Distribution (SSEPD) are working together with partners under the Ofgem Low Carbon Networks (LCN) Fund to develop a ready-made low cost solution. EA Technology is developing an EV charge control system to balance out the charging cycles of EVs at times of network stress.

To test the system the trial is simulating a future EV network, and to do this, clusters of EVs have been ‘created’.

If all that information strikes you as being a bit on the dry side, here’s an episode of Robert Llewellyn’s “Fully Charged” show that explains the project in a more entertaining fashion!

I watched a webinar last week in which some preliminary results from the project were released, but EA Technology had a few internet connection problems due to high winds in the North of England, and the feed gave up the ghost halfway through! To rectify that they’ve made a video of the proceedings available to all and sundry, and here it is:

There’s also a page on the My Electric Avenue web site where you can download additional information.

The data referred to in the video is based on the initial results from an ongoing survey. It explains that the approximately 200 participants who each leased a Nissan LEAF were split into two roughly equal groups. The “technical” group used “smart” or “controlled” charging, whilst the “social” group simply had their EV charging activity monitored. There’s obviously much more detail available from the video and accompanying documentation, but in brief:

  • Only ~5% of people disagreed with the proposition that “EVs are easy to live with”, however
  • 117 out of 193 people “struggle to charge away from home”
  • Of those 117, 12% intend to buy their LEAF at the end of the trial and 43% intend to lease it
  • Overall 17% intend to buy their LEAF at the end of the trial and 41% intend to lease it
  • Even after the “controlled” charging trial 80% of people like to charge their car until it is full
  • Of the people on the “technical” trial, 16% disagreed with the proposition that “My electric vehicle charges sufficiently in the time available to charge”

The concluding section of the presentation points out that the sense of “community” was very important to the success of the project, with “local champions” recruiting friends and neighbours into their “cluster” of EVs a vital element of that.

The final report on the My Electric Avenue project is due to be released by De Montfort University towards the end of October 2015. In the meantime if you are in the EV business and you would like to take a quick survey yourself on the topic of “Industry Views on the Impact of Cycling Electric Vehicle Charging” then you can do so over at:

Nissan and Green Charge to Deploy Second-Life EV Batteries

Posted on by

In a press release earlier this week Nissan expanded on some of the points Carlos Ghosn made in his speech to Nissan shareholders last month. “In his latest LinkedIn Influencer post, Renault-Nissan Alliance CEO Carlos Ghosn points to encouraging figures for electric vehicles, including the sale of the Alliance’s 250,000th EV in early June”

I don’t see other automakers as competitors when it comes to zero-emissions vehicles. They’re allies. And it is great to see the number of “Alliance allies” growing, as other automakers introduce more affordable EVs to compete with the segment-leading Nissan LEAF.

We reached the 250,000-unit milestone in early June, four-and-a-half years after the LEAF was introduced as the world’s first mass-market, zero-emission vehicle.

We also are seeing demand grow quickly in places where businesses and governments are joining to expand the charging infrastructure, and as more motorists get the chance to experience an EV.

In fact, computer engineer Yves Nivelle, who bought our 250,000th EV, was spurred in part by an incentive in France that encourages owners of older diesel-engine vehicles to trade them in on a new EV.

That sort of enthusiasm is quite common among our EV owners. Our EVs enjoy among the highest levels of customer satisfaction that we have seen for any vehicle. Operating costs are low, they require less maintenance, and they are fun to drive.

In other recent news, companies are forming to take advantage of re-packaging used EV batteries for other uses. Nissan recently announced it is teaming up with Green Charge Networks, an energy start-up, to reuse LEAF batteries to store energy for commercial and industrial buildings.

After many years of service, car batteries eventually need to be replaced. But they still retain enough charge for lighter chores.

When electricity rates are highest, in the middle of the day, a corporate customer can switch its energy use from the power grid to these re-packaged batteries. Or, even better, it can use the batteries to store unused energy from rooftop solar panels. Some homeowners already are doing this by connecting their solar panels to their EVs, to store the energy in the car’s batteries for later use.

Battery technology continues to improve, as well. In fact, the day is nearing when the typical EV motorists will be able to leave home with a full charge, go about their daily routine, and return home with ample charge remaining in their Nissan LEAF or Renault ZOE.

Later this year, you will hear more about our initial steps to increase the range of our EVs. Our goal is to eliminate “range anxiety” for our customers, as we continue our effort to make zero-emission vehicle a mainstream choice.

I missed it first time around, but additional information is available in the “Second-life” press release of June 15th:

Nissan Motor Company and Green Charge Networks, the largest provider of commercial energy storage, have joined forces to deploy second-life lithium-ion vehicle batteries for stationary commercial energy storage in the U.S. and international markets.

2015 Nissan LEAF battery pack

As part of the company’s commitment to sustainability and reducing greenhouse gas emissions, Nissan has conducted multiple research projects in Japan, the U.S. and Europe to use LEAF batteries outside the vehicle through 4R Energy, a joint-venture with Sumitomo Corp. formed in 2010.

In a new stationary storage application powered by Green Charge’s intelligent software and Power Efficiency Agreement™, the second-life energy storage unit has a cost advantage over traditional units, opening up new markets where incentive programs are currently not offered.

Engineering teams from both companies have worked together for more than a year to ensure safety, reliability and performance of this offering for commercial customers.

The first combined storage unit will be installed at a Nissan facility this summer, where multiple Nissan LEAF batteries will be configured to offset peak electricity demand, creating savings while also benefiting the utility grid. Systems like this also can be paired with renewable energy sources such as wind or solar to further reduce a facility’s environmental footprint and enhance energy savings.

 

Carlos Ghosn Reveals Long Range Nissan LEAF

I visited Bristol yesterday to attend the Regen SW “Community Energy Markets” conference. More from me on the event in due course, but before that I must point out that Bristol is “European Green Capital” for 2015. Here’s a video revealing how Bristol looks from behind the wheel of the current Nissan LEAF:

Earlier this week BBC News revealed how Japan looks from behind the wheel of the current Nissan LEAF:

According to the BBC:

The boss of Nissan, Carlos Ghosn, has not been shy about expressing his disdain for hydrogen. Instead, Nissan is betting on lithium ion batteries.

Coincidentally earlier this week Carlos Ghosn spoke at the Nissan annual shareholder’s meeting in Yokohama. Here’s the “Technology” part of his presentation:

All forthcoming products will reflect Nissan’s commitment to delivering breakthroughs that advance vehicle safety, efficiency, and connectivity.

During our discussion later in this meeting, we will update you on Nissan’s plans to introduce an autonomous drive vehicle by 2020. We are continuing to develop this exciting technology.

The vehicle that stands to my left features the latest versions of hardware and software that Nissan is developing.

The vehicle that stands to my right is another advanced technology breakthrough. It explores how far we can extend electric vehicle range by making changes to the battery.

Today there are only two reliable ways to increase electric vehicle range.

  • The first is to have a massive network of EV chargers, so that when you are away from home you have the ability to recharge easily.
  • The other option is to put a larger battery pack into the vehicle so that the driver enjoys greater range. However, with today’s level of technology, adding more battery means adding more cost.

As you know, Nissan has been one of the world’s foremost advocates for the development of recharging networks. With our efforts and the support of government and private sector partners, Japan has one of the most highly developed charging infrastructures in the world.

There are now more than 14,000 EV chargers, not including home chargers, in Japan. This means that EV drives already have the freedom to drive throughout mainland Japan without worrying about battery range.

Unlike customers in some other markets, where the charging networks are in earlier stages, customers in Japan who want to enjoy the benefits of driving a LEAF have no need to wait. Japan’s vast EV charging network already provides an incentive for you to move to Nissan’s zero-emission technology. And, during FY2015, the number of chargers in Japan will increase even further. However, that doesn’t mean we will become complacent and stop working to advance our battery and vehicle technologies.

We believe that, in the near future, Nissan can provide EV drivers with even greater “peace of mind” range, by offering comparative mobility to today’s conventional vehicles.

Nissan is exploring new materials and chemistry solutions in order to make thinner, lighter weight and less costly batteries. We foresee the day when you leave your home with a full charge, and are able to go about your day with no concerns…then return home with ample charge.

This video shows how we envision a routine day.

With this vision in mind, our advanced battery research will continue. But we will not wait for its completion to move forward. Later this year, you will hear more about our initial steps to increase EV range.

All of which puts me in mind of a couple of things a Nissan representative said in response to a question about “warranties” that was posed at the V2G workshop I attended earlier this month. It seems Nissan’s battery electric vehicle “warranty doesn’t prohibit V2G” and the “impact [of V2G] on the battery is insignificant”.

Solar PV Powered Public V2G Charging Launched in Utrecht

Earlier this week I attended a vehicle-to-grid workshop organised by Nissan Europe. This one was held in Utrecht in The Netherlands, where I discovered that the workshop coincided with the announcement of a new partnership between the City of Utrecht and a number of Dutch companies to ultimately deliver 120 “smart charging stations” across Utrecht. There’ll be more from me on the workshop itself in due course, but for now let’s take a close look at the world’s first publicly available solar powered V2G capable AC electric vehicle charging station:

The charging station itself is a GE DuraStation with added bi-directional capability. Sadly my wish of a few weeks ago has not yet come true, and the Tesla model S you can see in the foreground is still only capable of being charged by the DuraStation, which is IEC 61851/62196 mode 3 compliant. However the BYD e6 visible in the background IS able to discharge its batteries back to the local distribution grid.

This particular charger is situated outside the offices of LomboXnet, and hence integrated with the CHAdeMO compliant V2G system we reported on back in March, which stores the excess energy generated by the Solar PV installation at a nearby primary school. Here’s another angle on the event, showing Councillor Lot van Hooijdonk shortly after she cut the ribbon to officially open the charging station:

Another part of my wish from last month has also yet to come true. In Utrecht as in the United Kingdom, and despite the red carpet, whether you own an electric vehicle manufactured by Nissan, BYD or Tesla, and whether it prefers to be charged via CHAdeMO, IEC 62196 or a Supercharger, you still won’t get paid for allowing your battery pack to be used to provide an extremely useful service to the local distribution grid. However, perhaps mighty oaks from little acorns do eventually grow?

Whilst we wait to discover if/when/how that happens, here’s the video that Robin Berg of LomboXnet showed the attendees of the 3rd Nissan V2G workshop:

Renault-Nissan to Provide 200 Electric Vehicles for UN COP21 Paris Climate Conference

Posted on by

The Renault-Nissan Alliance announced today that they will provide a fleet of 200 all-electric vehicles as the official passenger-car provider for the United Nation’s COP21 climate conference in Paris later this year. The fleet of vehicles will include Renault’s ZOE and Kangoo Z.E. and Nissan’s LEAF and e-NV200. Here’s what a small part of it looks like:


According to the Alliance press release:

The partnership agreement was signed today between the Renault-Nissan Alliance and the General Secretary in charge of the preparation and organization of the 21st annual Conference of Parties (better known as COP21). The fully electric car fleet will shuttle delegates during the event from Nov. 30 to Dec. 11.

More than 20,000 U.N. participants from 195 countries are expected to attend the annual climate summit. It will be the first time the U.N. will use a zero-emission fleet for its entire passenger car shuttle at a COP event.

Laurent Fabius, the French Minister of Foreign Affairs and International Development and President of COP21, said that:

We are delighted to announce that the Renault-Nissan Alliance is an official partner of COP21 in Paris. Thanks to the Alliance’s fleet of 100% electric vehicles, it will contribute to our goal of achieving a carbon neutral event. The technology of electric vehicles helps reduce greenhouse gases in the transportation sector efficiently.

whilst Carlos Ghosn, Chairman and CEO of the Renault-Nissan Alliance, said that:

Electric vehicle technology is an efficient solution for a practical and affordable mode of transportation. This solution has a positive impact on the climate and air quality in our cities. It’s time to accelerate the shift to zero-emission mobility by working together with all parties concerned.

At this point in time I cannot help but wonder what Amber Rudd and her new team at DECC will make of being ferried around Paris in 100% electric vehicles later this year? Maybe they’ll be so impressed that they will follow the lead of Paris and:

Set up network[s] of more than 50 quick and standard charging stations powered by 100% renewable energy in strategic locations. The quick charging stations will be able to charge the EVs from 0 to 80% capacity in about 30 minutes.

Utrecht Gets V2G Based Energy Storage

Posted on by

In a ceremony at the Parkschool in the Lombok district of Utrecht on March 4th deputy Remco van Lunteren, officially opened the first Vehicle to Grid (V2G) energy storage system in Europe. The event was recorded for posterity:


The solar energy storage system supplied by Nissan charges electric cars but can also discharge their batteries in order to power houses. It helps to provide a higher return on solar power, reduces peak current on the grid and helps promote electric vehicles.  The opening of the V2G system is a sequel to the opening by Councillor Lot van Hooijdonk of a smart charging station from General Electric in Lombok on December 2nd 2014. The first charging station was unique because it had some built-in intelligence, and the V2G system adds an energy storage capability to it. Together, these are the first building blocks of Lombok’s Smart Solar Charging pilot project.

As the “Storage4all” project page puts it:

To create a truly smart grid using renewable energy, it is necessary to find a solution to the existing time differentials between generation and demand. The storage of energy is one way of achieving that.

Electric cars have a large storage capacity and are a major consumer of  future electric power generation. By making use of the storage facility of electric cars the “Smart Grid” can be made more sustainable.

In order to utilize the battery of an electric car for energy storage, it is necessary for the car batteries to be able to be discharged. In many cases this is not possible and the majority of EVs have internal protection against this. Only the Nissan LEAF currently has this possibility because of the Japanese market demand for storage (to protect against disruptions and power failures caused by earthquakes). The pilot project therefore initiated discussions with Nissan Europe and the provider of such a bi-directional charging system to achieve this in ​​Lombok.

Simulations show that there is much potential for storage of renewable energy in Smart Grids. Economically, it is not yet possible under current market conditions. The pilot project has ensured international recognition for this initiative, the development of the first European bi-directional charging station and a possible big roll out of them in Utrecht in the coming years.

Unfortunately market conditions here in the UK are currently also not economically favourable to this type of initiative.

Nissan and Endesa Pledge to Promote V2G in Europe

Posted on by
Reply

Nissan and Spanish utility Endesa have announced in a press release that they

Signed a ground-breaking agreement at the 85th Geneva International Motor Show that paves the way for a mass-market vehicle-to-grid (V2G) system.

The two companies have pledged to work together to deliver a V2G system and an innovative business model designed to leverage this technology.

If that sounds a touch unlikely to you, here’s the proof:

The press release goes on to explain that:

The two companies have agreed to collaborate on the following activities:

  • Introduction of V2G services in the European market;
  • Exploring the use of ‘second life’ EV batteries for stationary applications (including households, buildings, grid);
  • Designing and evaluating potential affordable energy and mobility pack offers;

One of the main challenges for electricity management systems is to assure grid stability. This situation is especially relevant in countries with a high level of renewable energy generation, and this will only increase in the future. The longer term zero-emission vision is for EVs to be at the center of a fully integrated system whereby owners can participate in wholesale energy markets using the power stored in the batteries of their electric vehicles, and thus significantly reduce their cost of operation. In a not-so-distant scenario, the EV user not only decides when and where they want to charge their EV, but how best they spend and re-sell the energy stored in their EV; receiving tangible financial benefits in terms of energy savings, while at the same time maximizing the use of green energy.

As is customary on these occasions the press release quotes executives from the two companies. Paul Willcox, Chairman of Nissan Europe said that:

We believe this innovation represents a significant development for Nissan Leaf and e-NV200 customers. Every Nissan electric vehicle battery contains a power storage capability that will prove useful in contributing towards smarter and responsible management of the power demand & supply of local power grids, thus reducing our EV total cost of ownership. Not only does this represent an opportunity for Nissan’s EV private and fleet owners, it could also support grid stability and fully demonstrate that each Nissan EV represents a tangible social asset.

whereas Javier Uriarte, Head of Market Iberia at Endesa, pointed out that:

The flexibility offered by V2G implementation in terms of storing and releasing green energy into the grid will further enhance the already significant and tangible benefits of electric mobility. This is why Endesa, together with its parent company Enel and partner Nissan, have decided to join efforts in promoting this technology.

Moving on to the technology employed:

The Vehicle to Grid (V2G) system consists of the Endesa two-way charger and an energy management system that can also integrate such off-grid, and renewable, power generation as solar panels and wind turbines. Using this equipment, a Nissan LEAF or e-NV200 owner can connect to charge at low-demand, and cheap tariff periods, with an option to then use the electricity stored in the vehicle’s battery at home when costs are higher, or even feed back to the grid with a net financial benefit. Electricity generated by solar panels or wind turbines can be used to charge a vehicle, to power the home or business, or to feed back to the grid.

This unprecedented agreement between Nissan and Endesa means that European countries can now review their current energy management policies in order to respond to the technological innovation of the V2G system.

Endesa has developed the ultimate low-cost V2G technology ready for the mass market after years of real-life testing. The company first showcased its V2G technology in 2008 in Smartcity Malaga, the Enel Group testing ground for smart cities. Later on, in 2012, Endesa presented the evolution of such technology at the ZEM2ALL demonstrator.

On March 12, 2015, as the culmination of the V2G system development, together with Nissan as automotive partner, Endesa will host a full demonstration of the market-ready and low cost system in Madrid.

Of course we’re not content with merely reading press releases here at V2G UK, and we have conducted an in depth interview with Olivier Paturet, who is General Manager of Nissan Europe’s zero emission strategy. Here’s a 2013 recording of Olivier outlining the raison d’être of Nissan’s ZEV plans:
