BMW Announce New “195 mile” Range i3

In a press release a couple of days ago BMW announce a new “go further” version of their i3 model – “The world’s first premium car designed from the ground up to be powered by an electric drive system.”.

The BMW i3 94Ah replaces the current 60Ah model and has a capacity of 33kWh thanks to the higher storage density of the lithium ion cells. The battery dimensions remain unchanged with more than a 50 per cent range increase in the standard NEDC cycle. This equals a range of 195 miles in everyday driving. The motor propels the BMW i3 from zero to 62mph in just 7.3 seconds (BEV) making the BMW i3 both the sportiest and most efficient electric vehicle in its segment.

Here’s a picture of the new i3, with a gratuitous i8 sports car in the background for good measure!

BMW continue:

The high-voltage battery in the BMW i3 consists of eight modules (each with 12 individual cells), and its capacity has increased significantly without any changes in structure or exterior dimensions. By optimising the cell-internal packages with more electrolyte and adapting the active material, BMW has succeeded in increasing cell capacity to 94Ah and overall battery energy to 33kWh.

The range of the new BMW i3 94Ah (BEV) in everyday use, on a full battery charge with the air conditioning or the heating on has been significantly increased to 195 miles. This is achieved with no subjective loss of driving performance and agility. BMW i models strike the ideal balance between efficiency, performance and range. From standstill to country-road speeds, the BMW i3 94Ah is on par with sporty, conventionally combustion engine powered cars.

The lithium-ion cells used in the battery are particularly notable for their high energy density and impressive cycle life: they are designed to perform their energy storage function over the vehicle’s entire lifespan.

The coolant of the air conditioning system is responsible for cooling the high-voltage battery very effectively. An optional heating system can also be used to heat the battery to ensure the optimum operating temperature of 20°C before starting off. The battery has been designed to last for the car’s entire service life. Customers receive an 8-year or 100,000 mile warranty on the battery.

A couple of other significant things to note about the new range are that:

The emissions of the BMW i3 94Ah with Range Extender amounts to 12g/km, a 1g/km reduction in comparison to the previous model while the exclusively electrically powered BMW i3 produces zero emissions locally, plus

DC Rapid Charge now available as standard.

The new models will be available from July, in Protonic Blue with Frozen Grey metallic highlights:

Nissan Electric Vehicles Prove Popular at UK Universities

In a news release today Nissan UK point out that:

The all-electric Nissan e-NV200 van has graduated with flying colours to become one of the most popular new vehicle choices for university fleets in the UK.

The multi award-winning van, which costs from just two pence per mile to run and offers zero emissions mobility whilst driving, is now in service on the fleets at more than 20 of the nation’s leading academic institutions.

University of Birmingham was the first fleet operator in the country to take delivery of the model when it added two to its fleet in 2014.

Since then, the University has added four more and the e-NV200 has moved to the top of the of the list for universities and colleges the length and breadth of the UK.

e-NV200s are now in service at universities including Bath, Brighton, Coventry, Dundee, Edinburgh, Exeter, Leicester, Leeds, Manchester, Manchester Metropolitan, Newcastle, Oxford, Sheffield, St Andrews, Swansea, the University of Central Lancashire and the University of Wales.

In addition, a number of other universities across the UK are currently trialling the e-NV200 as they explore the environmental and financial benefits it could have for their fleets.

Many moons ago I lived in Mayals and I’ve studied at Swansea University:

Nissan point out that in Swansea:

The e-NV200 Combi has been introduced as part of a broader commitment to sustainability and is operated as a pool vehicle, available on a booking system, by the information services and systems team.

As part of a seven-strong EV fleet, which also includes four Nissan LEAFs, the e-NV200 has proved a popular choice thanks to its size, flexibility and car-like driving dynamics.

Nigel Morris from the information services and systems team at Swansea University said:
 “Our EV fleet has already been a big success, cutting our carbon emissions by 4.5 metric tons and saving around several thousand pounds in fuel so far.

“The e-NV200 has made a terrific contribution to those figures as it’s proved so popular with staff. It’s a big vehicle that’s got lots of space for cargo or people but it’s very easy to drive.”

This news is all very encouraging of course, but I cannot help but wonder about something Nissan didn’t reveal to us this morning. Which of their long list of UK universities might actively be researching the application of vehicle-to-building or even fully fledged vehicle-to grid technology?

Perhaps the answer is “none of them”, but I am able to reveal that a UK University not mentioned by Nissan is in fact already so doing. Here’s an exterior view of the European Bioenergy Research Institute (EBRI for short) at Aston University:

and here’s what EBRI’s press release from a month or more ago has to say about the bright green box attached to the 24 kWh battery equipped 2014 model year Nissan LEAF pictured above:

Aston University has successfully commissioned the UK’s first permanent electric vehicle to grid (V2G) charging system.

This next generation of electric vehicle charging infrastructure allows power to flow both in the traditional way (grid to vehicle) and in reverse (vehicle to grid). The technology, developed in Japan to improve electricity supply reliability in the wake of the Fukushima disaster, is being investigated in collaboration with our leading industry partners, as a new method for energy storage and grid balancing services in Europe.

Please do read the press release in it’s entirety, and when you’ve done that also take a good look at the user interface of EBRI’s “load matching system”:

Exciting times for V2G enthusiasts here in the United Kingdom! Now that this pilot project is up and running there’s a few more urgent things to be ticked off on the to do list. How about OCPP 2.0 or even fully fledged British and international standards for “smart charging”, V2B and ultimately pukka V2G protocols for starters?

Here’s how the Open Charge Alliance explain the need for “Open Standards”:

The specification for version 2.0 of the Open Charge Point Protocol still seems to be absent from their web site however!

Storm Katie Cuts Power Across Southern England

On Easter Saturday the Met Office announced the impending arrival of another named storm from across the Atlantic:

Storm Katie is forecast to affect southern England and south Wales on Easter Monday

Anticipating the development of an area of low pressure, which will affect southern England and south Wales on Easter Monday, The Met Office has decided to name the storm Katie. This will be the 11th named storm since last autumn.

A National Severe Weather Warning for strong winds has been issued, covering much of Easter Monday.

The Met Office also issued a severe weather warning for the winds from Storm Katie across Southern England:

Issued at: 1031 on Sat 26 Mar 2016
Valid from: 0115 on Mon 28 Mar 2016
Valid to: 1400 on Mon 28 Mar 2016

Winds will strengthen markedly across southern England and through the Bristol Channel from the start of Monday, with the potential for 50-60 mph gusts inland and 70 mph gusts around coasts exposed to the south. Whilst there is a low likelihood of all areas seeing these strong gusts for a time southern coastal counties from Hampshire eastwards look most likely to see the strongest winds. These will then ease from the southwest during the morning, clearing from the east early in the afternoon. Additional hazards may include large waves around exposed coasts as well as a period of heavy rain.

Please be aware of the potential for disruption to outdoor activities and travel, as well as the possibility of fallen trees and temporary interruptions to power supplies.

On Easter Sunday the Met Office’s “Chief Forecaster’s assessment” firmed up the forecast a bit, saying that:

There is increased confidence in the likelihood of a period of disruptive southerly winds, veering westerly later. Winds are likely to be strongest in southern coastal areas, but there is potential for some very strong, squally gusts inland during the morning before winds ease from the west during the day.

Now the morning of Easter Monday has arrived, as have those “temporary interruptions to power supplies”. Storm Katie has done her worst, and here’s how the damage looked at 08:00 BST. First of all here’s Western Power Distribution‘s current power cut map:

Further east here’s Scottish and Southern Energy Power Distribution‘s power cut map:

and here’s one from UK Power Networks‘ for South East England:

Unlike WPD, SSEPD and UKPN don’t publish real time tables of the number of properties without power. SSEPD are however providing a “Live Storm Feed” for Katie:

According to their latest news bulletins:

Southern Electric Power Distribution has more than 900 engineering, technical and support staff on duty to deal with Storm Katie, and since last night power has been restored to 40,300 customers.

There are currently 28,497 customers in West Sussex whose power supply have been affected by Storm Katie.

There are currently 4,152 customers in Berkshire whose power supply have been affected by Storm Katie.

There are currently 2,893 customers in Dorset whose power supply have been affected by Storm Katie.

According to the UKPN Press Office:

There are currently 19,000 properties without power across South East England (Kent, Surrey and Sussex)

SSEPD are also “Live Tweeting” about the problems Katie’s winds have caused their network:

Solar Smart Charging in Utrecht with 150 Renault ZOEs

In a press release earlier today Renault announced that:

Renault has signed a letter of intent with the Dutch Utrecht City Council, ElaadNL and LomboXnet on Smart Solar Charging for electric vehicles.

The signature took place during the state visit to Paris of King Willem-Alexander and Queen Máxima of the Netherlands.

According to the letter of intent, the city of Utrecht could be the testing ground for the solar smart-charge project. Renault, Europe’s leader in electric vehicles, would supply a fleet of 150 Renault ZOE models through 2017 to the city. ElaadNL would handle management of infrastructures and the smart-charge standard, and LomboXnet would take charge of installing the network of unique public charging terminals powered by a 44 kW grid connection. Grid operator Stedin would be involved to balance supply and demand of the grid.

The Royal Family might have left better weather behind during their trip to Paris, but here’s a Renault ZOE charging outside the LomboXnet offices in Utrecht, in the rain:

Moving on to some more technical details of the Utrecht project:

Phase one of the project would involve setting up 1,000 smart solar-charge stations, powered by 10,000 photovoltaic panels in the Utrecht region. Infrastructure installation would run side by side with development of a car-share service of electric cars, powered by renewable energy, for Utrecht residents. The Renault ZOE R.Access connectivity and 22 kW charging make it ideal for car-share and smart charging applications.

So far so good, and then comes phase 2!

Phase two of the project would proceed with the partners developing a vehicle-to-grid ecosystem, with the network of solar chargers capable of both charging the electric cars and of feeding energy stored in the batteries of parked cars onto the grid to meet demand peaks. This could be the starting point for a new system storing renewably sourced energy.

As always at this juncture, one cannot help but wonder where and when the first “vehicle-to-grid ecosystem” will evolve here in the United Kingdom!

Nissan’s New Office Will Be Electric Vehicle Powered

Nissan announced at the Geneva Motor Show today that:

Its new regional office in France will house the largest grid-integrated electric vehicle (EV) system and second life battery storage unit ever installed in a building, anywhere in the world.

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.

Nissan announced plans to create a viable long-term solution to environmental protection in relation to energy use and storage at the COP21 climate conference in Paris last year. This included a partnership between Nissan and EATON on giving electric vehicle batteries a second life as stationary energy storage units and a partnership with ENEL on vehicle-to-grid integration. Grid integration trials have already begun in Denmark.

What Should Be In SEWTHA 2.0?

In case the six letter acronym (SLA for short) in our title for today means nothing to you it stands for “Sustainable Energy Without The Hot Air“, the title of a 2008 book by David MacKay, who amongst other things is Regius Professor of Engineering at the University of Cambridge. We first mentioned SEWTHA back in 2012, when Bill Gates praised it in an interview with the Wall Street Journal. I mention it again today because my attention was drawn by a bit of a barney (BoB for short) on Twitter between Prof. MacKay and Jeremy Leggett, who amongst other things is a founding director of solar PV company Solarcentury.

First of all here’s the BoB in question, including the V2G UK addendum!

 

In case you would like to listen to the edition of Evan Davies’ “The Bottom Line” on the topic of “Renewable Energy” under discussion, here it is:

http://bbc.in/1PIZD9G

Evan’s guests were Jeremy Leggett, Juliet Davenport of Good Energy and Paul Cowley, managing director of RWE Energy UK. Here are of few of my own “edited highlights”:

01:30 JD – One of the examples is Wyke Farm Cheeses. When they wash down the dairy every night and when they make the cheese, that they then anaerobically digest which creates a gas and they generate power. That’s one of our generators.

02:37 JL – A small cottage with bespoke solar tiles. these are different from the modules you use in solar farms or on a big installation on a commercial roof because they really are tiles. They go straight on the battens of the house. They generate electricity. They’re waterproof.

08:45 ED – I also wanted to talk about the physical constraints on whether you can get, in a country like ours, to 100% renewables. I’ve been very influenced by a particular book called SEWTHA by David MacKay.

09:30 JL – That book was published a good few years ago now. It’s out of date and I don’t think Dr. MacKay even believes that any more.

10:18 JD – We did some work, following David MacKay’s book actually, and used the work that he did. He went on to be the scientific advisor to DECC. He developed these pathways/models and we used them to look at how hard can you push the system to get it 100%. The UK has sufficient resource, whether it’s wind, whether it’s solar, to get to 100% on the current usage. [My emphasis!]

One of the things about climate change, it’s going to change the way we use power as well. So we saw last year energy usage in the domestic gas market dropped by 10%. 2014 one of the warmest years ever. You’ve also had the highest ever wind power production this winter. We’ve seen a lot of storms come through… So the parameters that David used in that book, I think we’re now looking for Hot Air 2.0.

11:30 ED – To give another example from the book, taking that it’s out of date, to get 50 kWh per day per person, and we’re currently using 125 kWh per day, to get 50 from offshore wind would mean filling a sea area twice the size of Wales. It would be expensive. It would be a very big deal.

One of things here, and it’s been much under-discussed in this area, is not only do we need to get our current electricity decarbonised, but we’re talking about decarbonising the transport industry to a large degree, and David MacKay’s good on this. You’ve got to almost double or triple your electricity generation, so not only do we have to replace the nuclear power and the coal that’s falling out of use over the next decade. You’ve got to replace that and add in plug-in cars. [My emphasis!]

12:59 JD – That’s what really exciting about right now. We’ve got a different problem on our hands. We’re going to have different technologies coming through, and we’re going to have to figure out how consumers use that. And actually the car storage part is really interesting because each car has a battery in it, and suddenly you’ve got a flexible power source that you can either use for transport or potentially use within people’s homes. And that piece of technology hasn’t really been thought through, about what that can really deliver [Juliet’s emphasis!]

13:45 PC – We see it in the press all the time. Wind turbines not running because the wind’s not blowing! The reality is that turbines generate around 85% of the time. They start generating at a very low wind speed… and then builds up to an optimum wind speed.

14:13 ED – We haven’t got yet a very efficient mechanism for storing electricity have we?

14:25 JL – Things are moving so fast. Let’s not forget, Apple is going to be mass producing electric vehicles four years from now. That is their stated intent. Each one of those is going to be a little power plant, and who knows how they’re all going to be hooked up to each other? It’s going to move so fast Evan, and I think this is the criticism that people like me have of, you know good guys like David MacKay with his book. They’re still flogging the idea of these vast centralised, humongously expensive centralised power plants, nuclear in particular, that take 10 years to construct.

The upshot of all this, apart from the BoB? More and more people are mentioning the concept of vehicle-to-grid technology in public pronouncements here in the UK. Andrea Leadsom at DECC assures us that she’s “as keen as mustard” on energy storage. That is of course nice to hear, but what do Physics & Chemistry have to tell us about the hard realities of distributed energy storage? And what about DECC & Ofgem too, with their assorted rules and regulations?

I might also have a minor quibble about Juliet’s “hasn’t really been thought through” remark. Some people have been thinking quite hard about V2H and V2G for quite some time!

Consumer Attitudes to Smart Meters

According to a press release from Smart Energy GB:

Consumers who have upgraded to a smart meter as part of Britain’s national rollout are continuing to demonstrate high satisfaction with their new technology, and greater control over their energy bills.

Smart Energy GB, the national campaign for Britain’s smart meter rollout, today publishes the third Smart energy outlook, the largest independent barometer of national public opinion on energy and smart meters. The research surveys more than 10,000 people around the country.

The bullet point from the “Smart Energy Outlook” report are:

  • More than half (52 per cent) of people with smart meters say their new meter is helping them save money
  • Eight in ten (80 per cent) people with smart meters have taken at least one step to reduce how much energy they use
  • Eight in ten (79 per cent) people with smart meters would recommend them to others
  • 85 per cent of those with smart meters say they have a better understanding of what they are spending on energy
  • People with smart meters are more confident in the accuracy of their bills (81 per cent) when compared to those with traditional meters (64 per cent)
  • Three quarters of people with smart meters (75 per cent) say that they understand their energy bills, while just 61 per cent of people using traditional meters said the same
  • Nearly three quarters (72 per cent) of people with smart meters say that they have the information they need to choose the right energy tariff, far higher than those with traditional meters (57 per cent)

Just in case you are now wondering “How do smart meters work?” here’s a video explanation from Smart Energy GB:

I wonder how many of the people surveyed by Populus would be interested in having an electric vehicle capable of powering their home, together with a smart meter and a “Smart Grid” that allowed them to optimise the charging and discharging of their EV’s batteries to their own financial advantage?

In partial answer to that supplementary question, here is our report on consumer attitudes to “Smart Charging” of electric vehicles

Riversimple Launch the Rasa Hydrogen FCEV

We’ve mentioned the Riversimple open source hydrogen fuel cell electric vehicle before, and we could not help but notice the countdown to the launch of their new “Rasa” model on their Twitter feed:

Today there’s an in depth article in the Financial Times about the Rasa and the reasoning behind it. Here’s the edited highlights:

Riversimple Movement is taking its hydrogen fuel-cell project — now 15 years in the making — to the next stage with the unveiling of its first production-ready, road-legal prototype and the start of a public trial.

In the autumn, about 20 people will have the chance to drive away a carbon-fibre Rasa, which may look slightly kooky with its rear-wheel spats and butterfly doors but packs four electric motors and can travel for 300 miles on a single fill-up.

“We’re not targeting the ecological market. We want it to look good,” says Hugo Spowers, who founded the company in 2001.

The Rasa was named for the blank-slate approach the company says it is taking to carmaking. Parts are chosen not on the basis of how cheap, light or powerful they are but how they will affect the business model.

“One investor told me this was the first time he’d seen a car built for a business model rather than the other way round,” says Mr Spowers.

Please read the FT article in full, but also take a look at what Riversimple themselves have to say. According to “Technology behind the car” section of their web site:

Every aspect of the hydrogen Mark ll Alpha has been created and interrogated for simplicity, efficiency, lightness, strength, affordability, safety and sustainability.

This first car is a two seater ‘network electric’ car, powered by a hydrogen fuel cell. The chassis is a carbon fibre monocoque made from very lightweight but extremely stiff carbon fibre composites. The monocoque chassis weighs less than 40kg.

Our car is very light – we have a target weight of 520 kg. It embodies various key features:

  • Four electric motors, one in each wheel
  • Motors as brakes – recovering over 50% of kinetic energy when braking
  • Super-capacitors to store this energy and provide most of the power for acceleration
  • A low powered hydrogen fuel cell ( 8.5 kW)
  • A body made of lightweight composites

It’s the synthesis of all these technologies that delivers the groundbreaking efficiency and range, many times better than inserting fuel cells into conventional, heavy, vehicles. The production prototype should do c.250 mpg (equivalent), with a range of 300 miles. Emissions are zero at tailpipe and c.40gCO2/km Well-to-Wheel – even if the hydrogen comes from natural gas.

We’ll keep you posted as the Rasa launch countdown continues. According to Twitter:

Here’s a teaser video to whet the appetite for the big reveal on 17 Feb – 5days to go!

[Edit – February 17th 2016]

The Riversimple Rasa has been unveiled today:

According to the Riversimple blog:

The new car reflects a simple idea that was first mooted in the 4th century BC by the great philosopher and scientist, Aristotle. It is the idea that something new begins, not with predetermined structure and characteristics, but with a blank slate – tabula rasa – moment of potential.

We set out with a blank slate, to design a car for the world in which we now live, shaped by the best technology available to us and answerable to our most pressing concerns. We set out to build a local car that will take people on their local journeys, in the way that they wish to travel, at a cost that is affordable – and without leaving a heavy footprint of air pollution and environmental degradation. To do this we selected a still evolving, but incredibly promising and safe technology. This is hydrogen fuel cell technology.

Here’s another video, this time revealing the Rasa in all its low drag glory:

I did enquire on Twitter where the nearest suitable filling station for a Rasa might ultimately be. I haven’t received an answer yet, but if it isn’t “Exeter” then I rather hope it will be “Plymouth”. According to the SWARM Project web site:

This project will establish a demonstration fleet of small passenger vehicles that builds on and expands existing hydrogen refuelling infrastructure. Three European regions will be participating in this effort: the UK (the Midlands and Plymouth), the Brussels area and Wallonia, and the Weser-Ems region in NorthWest Germany. Each of these regions will deploy a new hydrogen refuelling site to close the gaps in a continuous ‘hydrogen highways’ that leads from Scotland via the Midlands to London, connecting to Brussels and on to Cologne and Hamburg/Scandinavia/Berlin via Bremen.

The vehicles employed are low-cost, high fuel-efficiency, hybridised, light-weight passenger cars specifically designed for city and regional transport. These vehicles provide a complementary pathway to commercialisation to the large Original Equipment Manufacturer (OEM) of hydrogen fuel cell options, by allowing near-term rollout on a commercial basis to a wide range of users – in parallel with the planned rollouts for large OEM vehicles from 2015. Their deployment regions will gain the infrastructure, public exposure and technological understanding to act as seed locations for future large scale OEM vehicle rollout.

You will note that Riversimple are a member of the SWARM project consortium.

Robin Berg’s TEDx talk on “A new local energy and transport system”

I had the pleasure of meeting Robin Berg in Utrecht last summer at the launch of the LomboXnet solar PV powered bi-directional vehicle to grid system. Here is a video of Robin’s recent presentation at TEDx Utrecht:

Robin says many interesting and enlightening things, but for the moment please consider this one:

Tomorrow your car will run electric. The day after it will power your house. It will be 100% renewable, it will be 100% clean, and it will be the end of coal, oil and gas.

Storm Imogen Follows Floods in South-West England

The United Kingdom’s Met Office is just down the road from here in Exeter, and they have just announced that the newly named “Storm Imogen” is heading our way:

Imogen follows in the footsteps of her brother Henry further north and the unnamed storm that has just deposited 57.8 mm of rain on Okehampton in 24 hours:

whilst Exeter Airport endured gusts of wind up to 50 mph and a mere 21.0 mm of rainfall:

We have previously speculated about the effects of such storms on Western Power Distribution’s network in the South-West Peninsula, so here is how things look qualitatively at the moment, following today’s flooding:

and here’s the associated quantities

Here’s how Haldon Hill has been preconditioned for Imogen’s imminent arrival:

and here is the Met Office’s forecast [updated Sunday AM] for our back yard on Monday:

Do you suppose there will be another power cut here tomorrow?
