Team British Gas’ Robert Llewellyn talks energy and EVs

Right, on to the third of my posts about the RAC Future Car Challenge and Regent Street Motor Show. This time, a transcript of my interview with Robert Llewellyn or, as some of you may know him better, Kryten from Red Dwarf. As with the interview with Ben Collins, my words are in bold, Robert’s are in italics.

I feel as if I’ve been hearing about you ever since I arrived here today. You’re one of the case studies highlighted on the British Gas stand and, I guess, a bit of an ambassador for them. I noticed that you’re now driving a Nissan Leaf – have you got rid of your Prius?

No, no, I have a plug-in Prius as well, and a leaf. The plug-in Prius is actually my wife’s car, but I do drive it sometimes… when she lets me. She drives the Leaf a lot. We do have rows about which car we’re going to drive.

And you’re now running on solar power for your cars?

Yes. Not 100%, but I know that, because some really clever engineers know how to read the meters in my garage, that I did about 4,500 miles last year purely from solar energy, and I’ve done probably about 3,500 this year because the summer was lousy. So, less this year, but the solar panels have certainly given us an extraordinary amount of energy. It really makes a difference, there’s no question about that and it’s great to learn that from actual experience rather than just reading a leaflet that tells you.

Yes, seeing the stats on the wall is all very well, but you’ve actually lived those stats.

Yes, absolutely.

British Gas branded Vauxhall Apmera, as driven by Robert LlewellynSo, you were driving the Vauxhall Ampera in today’s Future Car Challenge. What did you think of it?

It’s a fabulously engineered car, really beautifully made, really easy to drive. I still have some questions in my mind because, if you were doing, say, a thirty mile commute every day, you wouldn’t buy any petrol. You wouldn’t need to, you’d plug it in at home and drive on electric. And then on the weekend when you want to drive to North Wales or Scotland, you could do it. But what that means is all the time during the week you’re dragging around a tank full of petrol and an engine, and then when you’re driving a long distance, you’re dragging round a huge battery and an electric motor. You kind of ask, “does this really work?”

So it’s either the best of both worlds…

…or the worst, and I can’t decide! I’m not saying one or the other, but I think you would need to drive it for a long time to find out. Certainly the people I’ve spoken to, particularly in the United States, who’ve driven them a long way are saying three or four thousand miles on a tank of gas, because they don’t use the petrol very much. From that point of view, it’s tremendous. I think it’s a huge step forward, and I congratulate General Motors on doing it. From an engineering standpoint, the joining of the electric and petrol, you cannot tell when you switch between them. Suddenly the petrol engine is running and you think, “I didn’t even notice that!”. It is extraordinary.  

Having driven pure electric, it feels like a slightly backward step but, that said, what I think it’s done is open that door for a lot of people to see, “Oh, actually, I could drive an electric”, and they then realise that they could drive a pure electric car. General Motors might not be thrilled with that concept, but it’s a proof of concept. You go, “Oh yes, I haven’t use the petrol engine for a month – do I really need it?”

I guess it does away with that whole thing of “range anxiety”.

Yeah. That doesn’t even come into it. I’ve driven the same drive [Brighton - London] in electric cars that were literally on the edge of their range and you’re saying, “Oh god, we’ve got another fourteen miles to go, are we going to make it?”. Didn’t even think about it in the Ampera, so it removes that altogether.

Were there any other cars on the Future Car Challenge you looked at and thought, “I wish I was driving that”?

The Renault Zoe. Today is the first time I’ve seen it outside a motor show – I’ve seen it going along the road today. They are, I think, another game changer; probably the next game changer after the Leaf. The Leaf is a mass-produced electric car that’s just around and people are starting to use and clock up 20, 30, 40,000 miles and they’ve very reliable and just work. I mean, we’ve done 22,000 miles in ours. The Zoe, I think, is the next one. It’s much cheaper to buy initially, has a slightly longer range than the Leaf, is slightly smaller but looks like a normal car, and it’s not really advertising the fact that it’s electric. I can understand that. I’ve driven weird electric cars that I’m happy with but you can get people saying, “Oh, it looks so weird, it’s not like a proper car”. Well these look like proper cars.

You do get some odd reactions, don’t you? I’ve seen some of the comments you’ve had on Twitter, Facebook and YouTube.

You could call them “odd”.

Talking with Robert Llewellyn at the British Gas standYes, being charitable, perhaps!

Yes, but I’ve noticed a slight shift in that there used to be a lot of hostility, and a lot of anger, which I couldn’t quite understand because it’s just a car – it’s made in a factory like every other car. But that’s fading now, and I think there are more and more people thinking, when they will a tank up and it costs £80 or £120, well, for the same amount of money, I could drive 10,000 miles. We’ve worked out that 22,000 miles has cost us around £300. Some of that charging we’ve done outside the home, but not very much – 10-15% maximum. Most of that is charging at home. Now, OK, that’s with solar panels and we try to use off-peak electricity where possible by charging at night.

That’s the other argument people make, actually, “Oh, you’re just burning coal to charge it, so it’s just as dirty as my diesel”. No, it’s not, and night is when there’s the least amount of coal burned and the most nuclear and wind used. It’s genuinely a very low-carbon transport system and, if you’re using solar as well, it drops it even more. 

What do you think is the biggest barrier to EVs taking off as a mainstream car?

I think, at the moment, it’s certainly the initial cost of purchasing. If you’re buying a car, which is the most expensive thing people buy other than a house, it’s a lot to ask of people to, instead of buying these cars that we’re used to, that we know work alright, and that you can refuel in a few minutes… buy this one that’s completely different and totally challenging. It’s a big step to make, so I think what we’ll see is, generationally, there will be a shift. So there will be people who are now between 15 and 20, who aren’t learning to drive as much as they used to, the number of people taking their test has dropped quite dramatically, but when they come to be interested in buying a car they’ll be more likely to rent them on a short-term basis, like a car club, and they’ll be much more likely to drive electric cars. Both my children, the first vehicle they moved in under their own power, steering it, was electric. There was none of that stuff with learning how to use a clutch, or hill starts, or anything like that.

I’ve driven a couple of Electric Vehicles, and they are genuinely a pleasure to drive.

They are, because they’re very, very simple and, and this has surprised everybody who’s had a go in my car, and these are blokes who are used to cars with a little bit of power [doing a cracking Jeremy Clarkson impression here], they are always staggered by their performance. They can really shift – you can still lose your license driving an electric car. 

It was interesting talking to The Stig earlier on, which is an odd thing to find yourself saying, and he was saying the Leaf is a perfectly fine car to drive.

Interestingly, for him, because we were all teasing him last night that he was just going to thrash it and go really fast, we did follow him through the streets of London and he was slightly more aggressive than I would be, but he did really well. He ended up with quite a lot of extra miles in his battery over other people who’ve driven the same car. That’s the skill of the driver, that he didn’t hammer it. He knew how to get it going, not accelerate too hard, it’s all those things you learn when you’re in an electric vehicle. 

This morning was the quietest start to a “race” I’ve ever seen.

It is bizarre, isn’t it, because they’re counting down, AND GO! 

Nothing. It is very different.

And what would you say is the one big advantage to EVs?

One of the things I think when I’m in London and it’s just jammed solid with traffic, it’s noisy, and all those engines are running but not going anywhere, EVs could transform that so that, sure, they could still be sitting in a traffic jam and that’s really annoying, but none of the engines are running. There’s nothing coming out of the exhaust, there’s no noise, it would transform our city. If taxis were electric, which they are thankfully introducing, that would make such a difference to the middle of London. If the busses were electric it would make an enormous difference.

The ground-level pollution for human beings, nothing to do with CO2 or Climate Change, is really toxic, and particularly for children. Strangely, one of the recent discoveries, is that the particulates from Diesel cars in particular, and trucks and busses, are low-lying. We’re OK, because it’s around our knees, but a toddler walking along the streets is breathing in… you may as well just give them a fag [cigarette for any US readers :) ], they’d be better off. It’s so bad for them!

There’s the takeaway line right there: Robert Llewellyn says, “Give your kids a fag – they’ll be better off”!

Hah! So not what I meant! But the pollution is a really toxic mixture that we’re pumping out into the atmosphere. 

So I think of it from the point of view of energy efficiency, and the local air pollution. Those sort of things are a huge advantage. You could then argue that it automatically spurs cleaner energy generation because people start to think they don’t want the electricity for their electric car to come from a coal plant, they want it to come from somewhere cleaner. That encourages people to start investing in those other areas of generating power. That and a combination of microgeneration. When you see microgeneration on a grand scale, Germany, Denmark, or Holland being good examples, where most houses have solar panels… you may say, “Well, they don’t really do that much” but when you’ve got 10,000,000 houses with solar panels on, it makes a massive difference to a national economy. 

Germany, last year, got 50% of their energy purely from solar. That is unimaginable in this country, but that is 20 years of investment, 20 years of putting solar panels on roofs, and when we were driving through Germany in an electric car we were playing I Spy for houses that didn’t have solar panels on them. You can find them, but there’s not many.

Again, huge thanks to Robert for his time and his interesting points. It was a real pleasure to chat with him and chew over some of the benefits and pitfalls of Electric Vehicles, and of home microgeneration. What do you think about what he said? Is there anything you particularly agree or disagree with? Do you have experience of running an electric car or, perhaps, powering it by renewable energy generated at home? Please feel free to chip in with your thoughts in the comments.

Ben Collins talks electric vehicles at the Regent St Motor Show

I mentioned yesterday that, as part of my time at the Regent Street Motor Show, I got to interview some of the drivers from Team British Gas. So today, here’s the first of two interviews. This one is with Ben Collins, known for, among other things, being The Stig on BBC’s Top Gear, and stunt driver on Skyfall, the latest James Bond movie. My words are in bold, Ben’s are in italics.

You’re in Regent Street after taking part in the Future Car Challenge. Did you manage to escape the rain showers in Brighton?

Yeah, we got away with that – as soon as we set off the clouds left and we had a pretty good run up, so sweet.

British Gas branded Nissan Leaf

Which car were you driving in the challenge?

I was in the Nissan Leaf.

You’re obviously much more used to driving high-powered cars, so how did you find the Leaf?

Well, I’ve driven pretty much everything; I suppose more famously for the fast stuff and the racing at Le Mans and what have you, and the supercars on Top Gear, but I just as much enjoy driving the other end of the spectrum too. I’ve driven the Leaf before and I was really amazed – it drives like a completely normal car, very easy to use, and really fast to recharge it. When it’s 80% drained, I think you can recharge it in 20 minutes through a high-powered socket. That only costs about £1.60, so it compares pretty well when you think of  what we’re paying for fuel these days. Yeah, we had a great run up.

I think it’s a cracking event. British Gas are sponsoring the Future Car Challenge, which is showcasing all this new tech so people can see it. The best thing for me is that they’re putting the network in place that means you can really take these things home and use them. Until then, who would you go to? You’d be wondering what company was going to supply the energy for it, so I think it’s great there’s a straightforward solution.

Some commentators say that EVs [Electric Vehicles] are not yet a viable solution for everybody; what are your thoughts on that?

That’s true; I mean, I couldn’t survive with just an electric car. I drive huge distances, and anybody that does a big commute intercity, which I do – it wouldn’t necessarily work for them.  Saying that, the majority of people don’t do that. The majority of people that do city driving would find you can do a hundred miles on this “tank”, and that’s a lot more than you think. I think it’s a genuine solution for a lot of people, perhaps even the majority of people.

When you think about how many households have two cars, it makes sense to have a long-range and a short-range when you’re saving ten times on the fuel. If you get a solar panel stuck on your house as well it really starts to work. Electric cars are cheaper to service, too, because you haven’t got all the running gear like gearboxes and all that stuff, or all the dirty stuff you get with a combustion engine. So they’re cheaper to service, and it adds up to big savings for a lot of people, but everybody makes their own plan.

So, it really depends on what your own circumstances are whether an electric vehicle will suit?

Yeah. With a Bugatti, you can empty its tank in twelve minutes. You would travel a decent distance in that time, but you wouldn’t get to work.

When Top Gear did their piece on the Honda FCX Clarity, they spoke to Jay Leno. He was saying that he thought technologies like hydrogen and electric would be the saviour of the petrol-engine car in the same way as the car was the saviour of the horse, freeing petrol cars up to be used more for leisure and fun while electric and hydrogen would be used for everyday transport. Would you subscribe to that line of thought?

Well, this has got some way to go on pure electric. At the moment, the best solution depends on what distance you travel. If you are a city driver, electric is perfect. If I was retired and I didn’t have to go far, electric would be the only car I would need. In terms of getting performance, distance and efficiency, for big commuting, you start looking at hybrids, and those are the sort of things that are winning at Le Mans at the moment – solutions where you get performance and longevity. I think the tech’s going to change and develop all the time and, as batteries improve, which they will, you’ll be able to update the battery in your car. So, I think the pace of change is going to be pretty rapid.

If it’s not too cheeky a question, what is your everyday car?

I’ve got a VW Transporter van, diesel, and that’s my family car. I’ve also got an Audi A5. The thing is I work away from home all the time, so I need my car. If I worked in the city I lived in, I would definitely be looking at something like the Leaf to go alongside the van. I guess it’s not the sexiest stable, but I’m saving up for a Ferrari.

The fact is petrol cars at the moment are the pinnacle of supercars – there’s no way around that as a fact. So all the money and development over the last hundred years has taken Ferrari, Porsche and Audi to where they are and it’s going take a while for electric to catch up. Tesla is nibbling at it, and Jaguar is coming in now too. It’s a good sign. If you think about the origins of cars in the nineteenth century, it started with electric and we’ve had a hundred years of developing combustion but the tech is there to make electric work. Motorsport is getting involved now, and so are companies like British Gas and Nissan. There are big companies involved with it now rather than purely being cottage industry with entrepreneurs doing it. The pace of development will kick up another notch.

Chatting with Ben Collins at the British Gas standWhat do you think is the biggest barrier to EVs taking off at present?

People still worry about the range, but that’s an individual choice. The barrier in my mind was always about the network where you can charge up. That’s still a problem, except that you can now have a charging point in your house, put in by British Gas, so that’s less of a barrier now. You don’t know what you’re missing until you get it. When Waitrose, Tesco, or Sainsburys put charging points in their car parks, when more councils start doing what they’re doing in London where you’ve got charging points in parking bays and tax breaks and all those sorts of things the barriers will really start to fall.

And what’s the biggest advantage of an EV?

It’s cheaper to run. That’s it – it’s just so much cheaper.

Huge thanks to Ben for taking the time to chat with me, for his interesting points, and for being gentle with a newcomer to celebrity interviewing! What do you think of what he said? Is there anything you particularly agree or disagree with? Let us know your thoughts in the comments. If you want more, read yesterday’s post about the Future Car Challenge and Regent Street Motor Show.

Team British Gas tackle the Future Car Challenge

Nissan Leaf setting off on the Future Car ChallengeThe annual Veterans Run from Brighton to London is a fairly well known event. Vintage cars meet in the seaside town and then all head up to London. What’s slightly less well known, perhaps because it’s a newer event, is the RAC Future Car Challenge.

The idea of the FCC is to take a bunch of electric, hybrid, and energy efficient vehicles from Brighton to London and see which makes the trip using the least amount of energy. This year, British Gas entered six vehicles in the challenge and invited me down to watch the start in Brighton, and interview some of the drivers in London’s Regent Street after the finish.

Why are British Gas entering cars in an event like the FCC? Well, British gas are highlighting the fact that they are the preferred charging solution provider for a number of the UK’s EV producers, including Nissan, Renault, Hitachi Capital Vehicle Solutions, Vauxhall and Toyota UK. So, when you buy your shiny new EV, the dealer will most likely try and point you in the direction of a British Gas installation.

We’ll get to what British Gas offer owners of EVs in a minute, but let me tell you about the day because, if you’re in the area next year, it’s well worth popping along. First up was the start of the Future Car Challenge in Brighton. The cars were on display in the paddock area on Madeira Drive at 7am, and then left at 30 second intervals from the start point. It’s a nice opportunity to see these vehicles up close, and any celebrities who happen to be taking part. The strange thing is just how quiet EVs are, or even hybrids. Everyone set off at a sedate pace (they were trying to do this on as little energy as possible, after all), and it was all very quiet. There weren’t very many people around but it was still a good way to start the day.

The big event, though, is the finish of the challenge. The cars all head off, and finish at the Technical Finish at Imperial College London. At this point their energy usage is measured, and they head to the Ceremonial Finish at the Regent Street Motor Show where, once again, the cars are parked up for the public to have a look around, and the drivers mingle with the crowds as they themselves take in the sights of the show.

There’s plenty to see here, from the ultra-modern EVs and Hybrids, including a retrofitted Morgan, to the classics of yesteryear including Model T Fords and even a car built by the Renault brothers in their mother’s back garden. It was particularly nice to see an Ariel Atom up close. I’m still no closer to my aim of actually trying one of these things, but at least I’ve seen one in person now!

The RAC were on hand with an economic driving simulator and the chance to win a Scalextric for the person who completed the simulated course with the lowest fuel consumption.

Add in live music, celebrity interviews, and some very impressive handlebar moustaches on the veteran drivers’ faces, and the day we well worth it. Not only that, but the Regent Street Motor Show is entirely free… you just wander down the street and you get to see the whole thing.

Right, now back to why British Gas are the preferred charging solution provider for all the companies I mentioned above. British Gas offer a range of services for EV drivers as part of their campaign to “change people’s relationship with the energy they consume”. The major offer they were highlighting at the event is free home installation of EV charging points (in selected areas of the country, currently London, East of England, Midlands and Milton Keynes). That offer also includes free access to the POLAR network of street charging posts until the end of 2013, after which you get to keep your home charging solution but need to pay a subscription for the POLAR network.  Still, given that the installation cost for the charging point alone is usually £799, if you can get the deal it represents a significant saving.

If you’re not in the mood for paying £799 for a charging station, you can have a dedicated electrical circuit installed from £375. It’s still not cheap, so hardly a throwaway investment, but it’s less than having a charging station. What you get with this solution is a separate fuse board that powers one outlet for charging an EV. This is apparently the minimum recommendation for charging a car as it avoids putting heavy load on the house’s normal fusebox.

British Gas have also created a special electricity tariff that has you on off-peak charges from 8pm to 4pm, the idea being that you can charge your car at night or during the working day. That’s not going to work for everyone, as many households make heavy use of electricity from 4pm to 8pm, but if your usage fits, it’s worth considering.

Finally, there’s microgeneration – solar PV (photovoltaic) panels particularly – to allow people to generate and use their own electricity. British Gas had a case study on display at the Regent Street Motor Show that showed how Robert Llewellyn, also known as Kryten from Red Dwarf, had used solar panels to keep his Nissan Leaf charged, resulting in a “fuel” cost of £17 per 1,000 miles. You can find more details here - the figures are slightly different (I guess they have been updated since the article was originally written in 2011) but you’ll get some idea of how having solar panels installed could work for you.

Now, all this was very interesting and it’s actually given me quite a lot to think about in terms of how I use and, perhaps one day, generate the energy we use at home, but there’s something else I was very excited about: those interviews with some of Team British Gas’ drivers… namely Ben Collins (previously Top Gear’s Stig) and Robert Llewellyn. I’m not going to bore you with an extremely long post, though, so check back tomorrow for Ben’s interview [now online here], and I’ll post Robert’s [now online here] on Wednesday.

Until then, I’m curious to hear from you. Were you at the Future Car Challenge start, or the Regent Street Motor Show? If so, what did you think? What are your thoughts on electric vehicles, and the services on offer from British Gas? I know EVs can be an emotive subject for some, so I’d love you to share your thoughts in the comments.

A better battery means a better electric car

This is a guest post by Sam Peters 

Group of batteriesWaltham, Mass.-based A123 Systems have developed a new form of lithium-ion battery that could change the game for electric cars, taking them from niche product to usable daily transportation. A123 has been in the electric car battery business for some time, inking a deal with Fisker Automotive to produce battery packs for the company’s Karma electric car, among other projects.

The newest batteries mark an evolution of the pioneering company’s lithium-ion phosphate battery technology, now with higher power output, greater density and many more recharge cycles before needing replacement. Here’s a breakdown of underlying technology and applications:

Technology 

Known as the Nanophosphate EXT system, the new batteries are based on a familiar concept and structure but pack advances in the way energy moves between the electrolyte, or the battery’s ion-carrying core, and the electrodes, or charge-carrying units that send energy to and from battery cells. A123 holds a slew of patents on proprietary electrolyte and electrode technology, with its newest-generation EXT batteries the culmination of years of lab research.

Claims have been vetted and verified by Ohio State University’s well-respected Center For Automotive Research, who had only positive things to say about A123′s new technology. With the world’s automakers willing to snap up any battery proven to make electric cars safer and better, A123′s future is bright despite some current financial woes.

Applications 

In electric cars, key battery characteristics are discharge rate, capacity, stability and number of life cycles. Pure electric cars need batteries that can provide large amounts of power on demand while providing long life without a loss of capacity. A123′s new batteries are purported to last twice as long as today’s commercial electric car batteries. The only downside to using an iron phosphate-based technology is a lower power density, around 160 watt-hours per kilogram, than with some competing technologies.

Uses for this technology could extend beyond just electric cars, from commercial uses such as cell phone towers to work in the lab carried out by organizations like Huntingdon Life Sciences. This battery will play an important role in low-emissions science institutes. Because the Nanophosphate EXT batteries do not require complex cooling systems to stay within their required temperature range, they are easier to mount and use on a daily basis, which makes them ideal for laboratory environments.  The new batteries are rated from -30 degrees Celsius to 60 degrees Celsius, a much greater range than lead-acid batteries or other lithium-ion units.

With potential to power electric cars with more usable power and longer battery life, A123′s cells are set to change the game. Their uses extend far beyond just in vehicles, but company executives are hopeful that profits from the EV market will continue to finance battery improvement technology and long-term growth.

What do you think of this? Would improved battery life and performance make you more likely to consider an EV as your next car? Can you see other applications for A123′s new batteries? Let us know your thoughts in the comments. 

What do you want your car to sound like?

I loved this article on the BBC News website, which talks about how researchers at Warwick University are experimenting with adding sound to electric vehicles.

See, electric vehicles are quiet. If you’ve ever tried to reverse a Prius out of a supermarket car park space you’ll know that people have no idea you’re ready to go and tend to get a bit of a shock when you start rolling. But full-on EVs are quiet at much higher speeds too, which poses an even greater danger to children, visually impaired people, or animals. So the idea is to add a speaker unit to EVs and make them emit a sound that signals their presence.

The question is, what should that sound be? Should it sound like a normal car? A UFO? An emergency vehicle?

Personally, I’d opt for the sound of a TIE Fighter from Star Wars. The thought of driving around town sounding like I’m defending the Death Star is making me smile as I write this.

How about you? If you could choose a sound for your car what would you have? Or would you, in fact, go for silence? Tell us your thoughts in the comments.

Personal transport gets a conceptual update

The Honda 3R-C, a new one-person battery electric vehicle concept, will make its world debut in Geneva alongside the EV-N concept, to be displayed for the first time in Europe.

Both the three-wheeled 3R-C concept, which envisions a single occupant vehicle for zero emission commuting, and the EV-N urban concept, draw on Honda’s working knowledge of vehicles utilising electric motors.

3R-C

This revolutionary three wheeled battery electric vehicle concept shows what a future urban transport vehicle for one person might look like. The battery electric drivetrain is mounted low in the three wheeled chassis, keeping the centre of gravity low and improving stability.

The 3R-C has a clear canopy that covers the driver’s seat while it is parked and not in use but converts to become the windshield when the vehicle is in motion. I have always found it very rare to want to travel somewhere without any luggage, even if just a briefcase, and the 3R-C features a lockable boot area in front of the driver.

The concept looks very interesting, and it will be fascinating to see if this kind of thing ever moves beyond “concept” and into mainstream transportation.

EV-N

The EV-N concept, previous shown at the Tokyo Motor Show, will make its European debut in Geneva. The EV-N is designed to show the potential application of battery technology in a small city car.

The EV-N looks very much like Honda’s 1967 N360 city car but also features solar panels to recharge it while parked, and two U3-X electric “unicycles” attached to the inside of the doors.

The two concept vehicles will be displayed alongside Honda’s production fuel cell electric vehicle, the FCX Clarity.

I’m still a sucker for traditional cars, and especial those that can be refuelled quick rather than charged up over a long period of time. Of the three vehicles, I’d say the 3R-C looks by far the most interesting, but it’s the FCX Clarity that I’d buy given the chance. All we need are Hydrogen stations!
