30 kWh Nissan LEAF Extended Test Drive

We have mentioned the new “go further” Nissan LEAF previously on the V2G blog, and now thanks to JFE Nissan in Exeter we have the chance to test the new 30 kWh battery pack equipped 2016 LEAF for ourselves. According to the Nissan UK web site:

Every full charge will give you a range of up to 155 miles.

I don’t know about you, but we’d like to check that claim for ourselves! At the very start of our test the odometer on the bright white LEAF we were borrowing read 6 miles as we collected it earlier today, and had advanced to 11 miles by the time we got back to base:

We had intended returning from Exeter to the wilds of the Haldon Hills via a main road. However before we left the Marsh Barton trading estate we consulted the LEAF’s handy traffic news feed, which revealed this:

According to Radio Devon “a caravan’s been abandoned in the inside lane on Telegraph Hill”! Hence we took the scenic route through some narrow Devon country lanes, and ended up with 20 miles worth of range left in the traction battery pack, according to the LEAF’s dashboard at least:

Having previously had some trouble using the rapid charger at Exeter Services, and having to avoid the motorway for other reasons on this occasion, we were in the perfect position to test the LEAF’s 13 amp “Electric Vehicle Supply Equipment” charging lead. We plugged it in at 18:30, and by 22:30 tonight the dashboard told us this:

More from us tomorrow on our Spring 2016 LEAF test, but for now we leave you with the inimitable Robert Llewellyn’s take on the new LEAF:

À bientôt, as I believe they say in France.

Nissan GB Announce 30 kWh LEAF

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

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

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.

2015 Nissan LEAF cutaway

2015 Nissan LEAF cutaway

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

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”.

Utrecht Gets V2G Based Energy Storage

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

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:

Is Apple Developing an Electric Vehicle?

According to Bloomberg the answer to the question posed in our title is a most definite yes! In a February 19th article Tim Higgins says that:

Apple Inc., which has been working secretly on a car, is pushing its team to begin production of an electric vehicle as early as 2020, people with knowledge of the matter said.

The timeframe — automakers typically spend five to seven years developing a car — underscores the project’s aggressive goals and could set the stage for a battle for customers with Tesla Motors Inc. and General Motors Co., both of which are targeting a 2017 release of an electric vehicle that can go more than 200 miles on a single charge and cost less than $40,000.

then adds that:

Apple representatives declined to comment for this story.

According to Bloomberg, however:

Apple began around June an “aggressive campaign to poach” employees from A123 Systems LLC, the Waltham, Massachusetts-based battery maker said in a lawsuit against Apple filed this month.

Apple hired five people from A123 and has tried to hire battery experts from LG Chem Ltd, Samsung Electronics Co., Panasonic Corp., Toshiba Corp. and Johnson Controls Inc., according to the lawsuit.

Bloomberg also talked to Tesla CEO Elon Musk, who told them:

That Apple was seeking to hire away his workers, offering $250,000 signing bonuses and 60 percent salary increases.

It seems as though when it comes to EVs, there’s never any smoke without fire?

[Edit – Saturday February 21st 2015]

This morning’s edition of The Economist includes an article on the Apple EV rumours:

APPLE’S ability to make desirable iGadgets designed for easy portability is beyond question. Reports emerged this week that it is planning to make a mobile device that will instead carry its users—an electric car. Apple’s plans are unclear and unconfirmed. By some accounts it has put a few hundred people to work developing cars to match Tesla, another Silicon Valley firm that makes fast and luxurious battery-powered saloons. Others reckon that it is working on a self-driving car.

Plenty of other tech firms are turning their attention to cars. In February Uber, a firm that provides taxis through a smartphone app, said it would set up a laboratory in Pittsburgh to develop self-driving taxis. Sony recently put money into ZMP, a self-driving car startup; Google has been working for years on driverless cars.

The Economist doesn’t sound optimistic about the future for the alleged Apple EV:

The likes of Apple may not know much about pistons and gearboxes, but the big challenge for electric cars is batteries. Battery-powered cars have many advantages: refuelling at home, cheap running costs and no tailpipe emissions. But the market for pure electric vehicles is tiny:

Expensive batteries make for costly cars, and limited range and a lack of recharging infrastructure have put off most drivers. Nissan’s Leaf, the world’s best-selling electric car, attracted only 40,000 buyers last year compared with the 250,000 the company once hoped to shift. Tesla aspires to enter the mass market but so far it has dealt with the battery problem by putting lots of them in a big, expensive car, thereby limiting it to a luxury niche. The plunging oil price dents the prospects for electrification still further.

and concludes:

Tech firms may be better off working with carmakers, to develop the software that will provide the brains of the self-driving car, and to improve the range and battery costs of the electric car. In the motor industry, supplying the key parts is generally more profitable than putting the cars together, even if you do not get your company’s badge on the bonnet. In the future cars will be different but the brands will probably be much the same.

 

UK Smart Grid Vision Lukewarm on V2G

Last week the United Kingdom’s Department of Energy & Climate Change published their new “Smart Grid Vision and Routemap“. According to DECC’s introduction to the document it:

Sets out the wide ranging benefits that smart grids will bring, for example: minimising consumer bills; allowing consumers to play a more active role in managing the energy system; increasing energy security; helping to facilitate the integration of low carbon technologies; and supporting economic growth.

 

Great Britain is already recognised as a European leader with respect to the investment in smart grid research and demonstration projects and has begun the nationwide rollout of smart meters, which will help improve network management and facilitate demand response. The Smart Grid Vision and Routemap outlines what action is now needed to build on this initial success to ensure the benefits are realised as soon as possible.

Delving into the routemap itself, I searched for any substantive reference to electric vehicles in general, or vehicle to grid technology in particular. Here’s what I managed to dig up. Firstly a diagram illustrating where EVs fit into the grand design of the future Great British Smart Grid:

February 2014 UK "Smart Grid Vision and Routemap" graphic

February 2014 UK "Smart Grid Vision and Routemap" graphic

Click on the image to see a larger version, where you will note it is anticipated that the “Traditional Distribution Network Operator, managing a largely passive network” will be transformed into a “Future Distribution System Operator, managing an active network supporting local balancing & system optimisation”. Electric vehicles are down in the extreme bottom left hand corner, under the heading of “Flexible Demand”, apparently totally separate from either “Energy Storage” or even “Distributed Storage”.

Secondly there is a forecast for the future growth in the number of EVs humming along the UK’s highways and byways, which looks like this:

February 2014 OLEV projection for number of electric vehicles deployed in the UK

February 2014 OLEV projection for number of electric vehicles deployed in the UK

The significant bullet points in the document that mention electric vehicles seem to think that an EV is much like a heat pump. A future British smart grid will:

  • Minimise consumer bills – more efficient use of network assets helps reduce the need to invest in costly infrastructure and ultimately reduces the costs passed through to consumer bills. It is estimated that by 2050, smart grids will reduce the cost of additional distribution reinforcement needed to accommodate the connection of low carbon technologies such as heat pumps, solar PV and electric vehicles by between £2.5bn and £12bn (a 20 to 30 per cent reduction)
  • Enable new low carbon technology to be deployed – heat pumps and electric vehicles will deliver significant carbon reductions, but will increase demand on the electricity network. Using smart grid technology to phase operating times, these devices can be incorporated into the network in conjunction with distributed generation to balance supply and demand, reducing the need for costly network reinforcement.

Finally there is a reference to another document, “Driving the future today – a strategy for ultra-low emission vehicles in the UK” from the Office for Low Emission Vehicles, which contains a few more bullet points about electric vehicles combined with smart grids:

  • The mass adoption of ULEVs will have significant implications for the energy sector at both a local and a national level. As the number of plug-in vehicles on our roads increases, so will the demand for electricity, placing additional pressures on the electricity system.
  • However, ULEVs can also help to balance the demand for electricity at peak periods and support the efficient use of energy by consumers. This will be facilitated by the introduction of intelligent power supply networks (smart grids) and the roll out of electricity smart meters across all domestic properties in the UK by 2020.
  • The majority of plug-in vehicle owners will charge their vehicles at home, at night time, during the off-peak period. This is not only most convenient for drivers, but also maximises the environmental and economic benefits of plug-in vehicles by using cheaper, lower carbon night-time electricity generation.
  • To help people charge at home as easily as possible, the Government is ensuring that smart metering in Great Britain includes the functionality to support charging of plug-in vehicles. This will allow recharging to happen when it is cheapest for consumers and the energy system (subject to appropriate technology in the chargepoint or plug-in vehicle).
  • Plug-in vehicles could also act as distributed energy storage during periods when renewable (or nuclear) electricity generation exceeds demand. This could happen during the life of the vehicle or as a potential end-of-life use for batteries. There may even be the potential for these vehicles to be used as an energy store, to power the house or feed electricity back to the grid at peak periods.

At long last a reference to something resembling V2G, or at the very least V2H! Moving on to page 71 of “Driving the future today” I finally found what I was searching for, an explicit (if somewhat grudging) reference to V2G technology. I reproduce it here in full:

Vehicle to home and vehicle to grid

As the smart grid and battery technologies develop, there may be the potential for plug-in vehicles to act as backup energy sources for homes and supplement the grid during peak demand periods. Nissan already offers a ‘power control system’ to its customers in Japan which allows their LEAF car to power a house for up to two days from its battery pack. Development of this technology was brought forward following the Fukushima nuclear reactor disaster.

 

There remain issues about the potential impact of taking charge from vehicles on battery life and the investment necessary to facilitate this on a large scale. However, Government will continue to talk to industry and researchers in this area and monitor developments.

Storage has the technical ability to provide a number of benefits to the electricity system – for example, smoothing supply profiles from variable generation and potentially reducing constraint costs by allowing generation to run during periods of low demand. It can also potentially save or defer network upgrade costs that may be required in the future to meet peak demand. Sixteen organisations have recently been awarded a share of £2 million by Government to help develop innovative storage solutions for energy. This funding is helping to drive forward innovation and encourage private sector investment.

The only trouble then is that none of those sixteen projects mention V2G or V2H, although both the the EVEREST project and Aston University’s Hybrid Batteries to Grid project refer to “‘Second Life’ EV batteries” but unfortunately not to EV batteries in situ. It rather sounds as though “Storage to Grid” (or S2G for short) is a more likely prospect here in the United Kingdom than fully fledged V2G.

The Nissan LEAF – Now Built In Britain

The very first British built LEAF electric vehicle has recently rolled off the production line at Nissan’s plant in Sunderland. British Prime Minister David Cameron was there to celebrate the event, as were some cameras. Here’s what one of them recorded:

Commenting on Nissan’s £420 million investment Mr. Cameron said that:

This plant, all of the people who work here, the cars being produced behind me, are the best possible rebuke to those who say “In Britain we can’t design things any more, we can’t make things any more or we can’t export things any more. You’ve shown here at Nissan in Sunderland that we can, and we can do it brilliantly.

As the reporter points out:

The new LEAF boasts over 100 improvements and uses an advanced lithium-ion battery, which is also manufactured at the Sunderland plant. Updates include an increased driving range of 123 miles or 199 km, and the ability to recharge in half the time of the first generation LEAF.

 

More than 54,000 LEAFs have been sold worldwide. Nissan says the new LEAF is the first in a number of pure electric vehicles that it plans to launch over the next few years.

Unfortunately no mention was made of the “vehicle to home” technology that Nissan have been trialling back home in Japan, let alone fully fledged V2G. Maybe Mr. Cameron will announce some significant Great British investments in the design of such esoteric devices in the near future?
