ICE’d, ICE’d baby

The past few weeks have seemed really busy.  End of financial quarter, new aspects to my job and a lot of travelling.

I am currently racking up around 1,000 miles a month in the diesel which feels terrible.  It’s all the best kind of travelling for the beast but still, averaging 40mpg in a 275bhp car is only being offset by the fact the other 750miles I do a month is in an electric car.

It feels dirty 😮

Whoa, that’s a big change

Mmm.  It being late in the year, my manager was almost insistent that I did the miles in an ICE but after doing the majority of miles in the Leaf the past two years, it is really odd.

Let’s start with the whole getting the car started.  It’s noisy, really noisy.  It is slow, it’s a good 10 secs before I am allowed to put the car in to gear.  Yes, gears, there are 6 of them.

The car still opens without the key and there is a start button.  But it makes the weird, low level shaking once the start button has been pressed and there’s this weird, smelly liquid you have to put in.  I filled up the car yesterday and that’s definitely a procedure that is no longer a habit.

When I am stopped at lights, there is this noise coming from the front and underneath of the car, which you do get used to after 10 or so miles.

I am not convinced it will catch on.

The title is ICE’d?

I am off on my ICE’d (internal combustion engine) travels tomorrow.  I appreciated the Leaf today.

Monday afternoon, post piano lesson, is when I typically charge the Leaf.

I approached the chargers outside of work to find a VW and Nissan taking the two spaces in front of the Evalu8 charges.

Thankfully, there are other chargers on site and I drove over to my favourite only to find a beautiful Ampera charging up.  Or not, as it seemed to be finished.

The dilemma: to see if it would surrender the polar charge cable from the pod or not.  I was pretty sure it would not let me unplug if it wasn’t charged.  So did the deed and closed the Ampera’s charge port door.

Which set off the alarm! 😮

At this point, despite not causing any damage, I felt as guilty as hell and was probably the same colour red as the Leaf.  I froze only to see some colleagues walking across the way looking with interest my way.  Or possibly towards the screaming Ampera!

I waved, left handed as the charge cable was in my right hand – what else do you do?

Deciding that either the owner would come or not, be happy and cool or not, I tried to plug my car in only to find my considerate park meant that the cable just wasn’t long enough.

I carefully place the cable on the ground and repositioned my car.  It was a pretty good park, shame I didn’t have a camera to hand.  Both the Leaf and the Ampera could have their driver’s doors opened but a paper back could not have been slid between the narrowest gap.  Think of a V with the Ampera facing forwards with the Leaf lined up frontwards in against it.

Not for the first time did I thank the person in Nissan who said an all round camera would be useful on the Leaf.

Plugged in and started the charge.  I left the cable unlocked, just in case the Ampera did need a top up.

I returned to get the car early – today was never going to be a long stay in the office.  The Leaf still had the cable and a charge of 80%.   I returned the plug and cable to the pod and manoeuvred out to start the journey homewards.

What a difference a year makes

one yearMuch has been in the news lately about the removal of subsidies for home owners who are deciding to move to micro generation of electricity through the use of solar panels.

We were in the 2nd wave of adopters and missed out on the 17p per unit feed in tariff or FIT.  To be honest though, that isn’t why I am writing.

We moved in to a house without solar cells.  It did however have a south facing roof which made it a logical move.

FIT is great, do not get me wrong.  We’re getting around £400 annually from this.  Solar generation though is providing move than the income from FIT: the graph to the left shows (in dark blue) our electricity consumption per quarter.

Solar cells mean we’re using less electricity from the grid.  Full stop, that’s something no-one can take away from us.

We’re benefiting most during the summer months, as we live in the northern hemisphere and there are less day light hours providing good energy levels during the winter.

That’s really the point: if the feed in tariff disappears, everyone with solar cells will have no incentive to feed in.  That disappears.  We generate around 4MWh a year.  We use around 4.5MWh a year, currently (1.2MWh of that is for transport, with the Leaf).  At the moment, much of what we’re generating, we’re not directly using.

So?

So we’ll get a battery, which will reduce further the amount of energy generation the UK will need.  Which would make it completely unprofitable to do electricity in a large scale if everyone did that.

In fact, we’d be tempted to go the whole hog, potentially, and get a combined hear and power boiler.  At £6K they cost around the same as photovoltaic cells generating electricity but the are a great complement as when you’re heating the house, it tends to be when the sun isn’t shining.

For the UK in general, that could mean the end of our reliance on fossil fuels for central electricity generation, but it wouldn’t be as efficient or as well maintained.

Has this been considered to the full?

What about the Leaf?  Is that making a huge difference?

Actually, no.  Since we installed the home charging point in June 2014, we’ve charged the car with 1.2MWh of electricity – about £168.

In total the car has had 2.4MWh of electricity since January 2014.  So we’re getting around a third from home, the rest while out and about (although we don’t know how long that will last).

If we didn’t have the electric car, the solar cells would be producing pretty much all our needs, albeit, not necessarily when we want to use the generated energy.

But that is very cheap driving.  £336 for 18 months worth of journeys or 3-4p a mile if we’d bought the electricity from the grid – much less if we generated it!

STEM ambassadorship – my experience

One of the best managers I ever had in BT was a gentleman called Jeff Patmore.  Jeff was a senior manager who had come in to BT as an apprentice.  He was clever, experience and very talented.  Who wouldn’t want to work for someone like that? a
Prior to working for Jeff, I had considered leaving BT and working as a contractor: I was recognised as a good programmer and mostly could do the usual work load on a Monday.  I wanted to be working at the next level but was finding promotion difficult.

Jeff gave me some challenges and more importantly the experience I lacked in achieving more in a large company.  Jeff was also keen that I gave some of that back.  I’d spoken to Jeff about my early career (working through the Commodore 64 user manual then the next level programming manuals, then taking other people’s programmes as frameworks for achieving our families goals) and my college and university experiences.

I didn’t start coding at 10 with a view to being a professional coder.  I didn’t know what I was doing was anything special.  All the pi-jam equivalents and taster days at school did not inform me that this was what I should be considering as my life.  I am so glad I stuck with it.

I thought the ambassador programme with STEM would help me help the up and coming generations to work that out before they got on the wrong course at university.  (This really happens.  Please ensure you have something you are reasonably passionate about studying for 3-4 years.  If you don’t and you quit after 2 months, drop it from your CV and get a job fast.  These gaps do not make you a great employee on paper – strange but true).

How to develop a career

The subtext here is as a programmer, but it does translate.

Get experience: mine was on the playground and I never counted it.  Actually what that demonstrated was a will to sell and see how far my “product” would get me.  I made no money to speak of, but I enjoyed learning how to make my code work on other machine and I liked people saying wow to something I created.

I still like these things.  What I do now is way more impressive.

When someone is hiring they essentially look for three things: loyalty, honesty and ability.  Sometimes I swap ability for drive or ambition, but essentially your first job, as a programmer, you don’t have much ability.  So I am looking for something else and that’s determination to learn.

Most jobs have boring and difficult bits: without your willingness to learn, you are essentially a one trick pony.

We see from the image that you have a degree, yet you’re not talking about that?!

No, I’m not.  I saw my degree as giving me proof of ability and loyalty and honesty.  Some people who hire do not view degrees that way.

I understood from my early programmes, that computing was a huge and complex subject.  My degree opened up my mathematical and computer science experiences and developed them.  It also provided direction in what to study effectively.  Completing a degree shows you can make a decision effecting three years of your life and have the determination to stick with it.

If you are not (planning on) doing a degree, look for an employer who will give you that experience and framework to learn and apply.  My learning has never stopped.

My degree was undersigned by the British Computer Society and as such, we learnt a lot about successful software engineering.  For me, though it was not easy, it was the best course for me.  I use principles I learned in my degree every day.

The degree will help you get an interview, it will not necessarily get you a job.

Back to the career

For one of my recent jobs, I sent over access to some of my programmes.  I am passionate about using computers to help people succeed in the work lives and the role was pretty much asking for coding experience.

I wrote a brief on each one and let the CV reviewers make a decision.  I got the interview despite not having recent programming experience because they could see I care about my output.

If you are coding and looking for that first job, there is nothing wrong with doing this.  Many roles are being “assessed” to test you can do what you say you can do.  You are helping that conversation.

Practice outside of work: for goodness sake, do not just write for your clients.  I learnt imagemagick, barcode decoding, OCR, GPS manipulation, voice XML, hadoop, prolog (revisited), python, MS Powershell all for personal use first.

I do a test with my code.  I code to sleep late, wake around 2am and try to use my code.  If I can use it first time and achieve my goal, I judge it to be good code.

Since 1985, I have never had a call at 2am from a customer who can’t achieve a business critical function as a result 😉

Complications

The past six weeks have brought many changes with them, not least summer holidays.
As a dual parent working household, the summer was always a chance to enjoy “normal working hours” and my son was safely amused at the child minder’s.  He had company and care.  A real break from school, but also from home.

When he stopped going to the child minder’s as he left primary school, that disappeared.  The first couple of weeks, we try to take the time off but after that, he is effectively on his own.  My husband works from home, so he does have company for lunch.

At least, that’s the impression we get.  He is a gamer, so he has the world at his finger tips, certainly all his friends.  Skype (or other voice/video comms service) on one device, games on another.

At 14, he goes out to get some food for lunch (enforced break from games and, hopefully, some useful life lessons) and this year he has moved away from simple meals on to ones with either some vegetables or rice or pasta or potatoes which he cooks from scratch.

We discuss meal options in the evening for the next day.  We discuss measurements for the main starch (i.e. how much from the bag of rice or pasta makes a portion).

Of course, this was put to good use as number one son headed out on his trial Duke of Edinburgh award.  My son is aware that if you are putting peas with your rice, you don’t need a full 50g of rice, you can just have 40-45g and still be happy with your meal.  We had progressed as far as fresh carrots before school started again.

Useful tips for him once he leaves home.  May be next year, he can help with the preparation of tea in the evening one day a week or fortnight.  Spaghetti anyone?

A load off my mind

I have to be honest: I want one!

I am sitting at home on a rainy Sunday morning, waiting for the oven to switch itself on to cook the Sunday roast.  We’re having it late today as the 45th Ipswich to Felixstowe vintage car run is due to go past our place in ninety minutes or so.  It’s a great event, and though the weather may dampen the grip, the enthusiasm will be high and all will enjoy the ride past!

Two years ago, this was our first weekend in our new house and watching the rally was a very welcome break from unpacking boxes. 🙂

That’s not what I would really want.  I saw the news of Tesla’s Powerwall and thought, finally, something to enable us, in Blighty, to make good use of the Sun’s energy which is freely deployed while we’re at work, school or out for the day.

Why do you care?

We got solar panels installed late August last year and despite it being winter, we’ve managed to collect 2.5MW of electricity, which is doing great things feeding it into the grid, but unless we’re totally organised and got the washing machine, dish washer and hot water running off timers the only item in the house when it’s sunny is my server.

It would be great to store the peak in batteries and run the cooker in the evening or even charge the Leaf.

Sounds good.  So when is it arriving?

Of course, it’s not. 🙁

Like the Roadster the release is initially in the USA.  But it is really competitively priced.  Like many, even with the grants and feed in tariffs, it wasn’t until the price came down that it made sense for us to get solar panels.   Given our life style (you know, out of the house during daylight hours) it seemed like a nice thing to have but not an essential.

A £2,000 Tesla Powerwall (read battery that charges up from the sun and releases when the solar panels are no longer providing the power directly) makes that useful and the return on the investment should be within two or three years.  Teamed with a Combined heat and power unit during the winter and the potential for going off grid looks good rather than an absurd pipe dream.

Tesla are well placed to do this.  They have access to battery technology: their chief research has focused on this for their electric cars.

Maybe other car manufacturers will follow suit and beat Tesla to it in Europe?

Haven’t you been good!

Driver performanceIt’s been incredibly busy the past few months so this is a long time after the fact.  I thought you might like to know…

What?

Well, we had our first service of the Leaf (although to be honest, we have enjoyed owning it so much that it really didn’t feel like a year).

It was a bit cheaper than we were expecting which was good.

It also gave us a reasonably comprehensive set of results from the battery testing.

In an electric car, the battery is everything.  The longer you can keep it performing well, the longer the range of the vehicle and the more confidence you have in it.  It should also prolong the life of the car with its first battery.

The life of the battery, according to the Leaf’s manual, is dependent on many factors not least the way you look after it.  Being a lithium ion battery (Li-ion) it prefers being often and lightly used (i.e. not running the battery down) and not too many full charges.

Apparently, the way we are managing the battery is all good.  Which is a little surprising.

Surprising? Does that mean you been reckless?

No, I have just used the car as I would a car with an internal combustion engine.  I try to ensure it doesn’t go past 15% before charging and I don’t bother charging it if it is above 60% in my normal day to day running.

We have done the odd long run and too be honest, I’d like to take it a bit further this calendar year.  I just wasn’t expecting the way I run the car to give us five stars.

Over the winter, we have found we are using more of the battery for the basic runs to work, for example.  It will be interesting to see how it compares during the summer.

Nice to know…

The other piece of news the past six weeks has been the loss of the Source East and London cards.  These allow us to charge the car at work for example.  Instead, all of our charging has been performed at home.

Expensive! Would it be better to have a petrol car, especially given the fuel prices…

Actually, no.  I thought it would be, but as we have solar cells we charge for free during the weekend and only a few pence a couple of times a week.  This has had very little affect on our electrical consumption.  The other surprising thing is we’re not having to queue for fuel.  Time wise, I get back a good 30 minutes a month.

I cannot believe how cheap petrol is at the moment and filling up the motorbike is a good deal less than it was.  For convenience the electric car has it beat for the commute.  I don’t know if the car is better at its estimation levels or I accommodate it more, but a couple of evening charges a week is plenty with a top up on either Saturday or Sunday.  I now find I can get 90 odd miles from an 80% charge even with the heater on.

What has been strange is not being able to use the Waitrose charging points.  We haven’t lost the car yet, but nestled in with other cars in the shopper’s car park, it is very ordinary looking.

Having ordered replacement cards when the Source East one was lost and the Source London one stopped working as it snapped during use, it did feel a little restrictive.  But in reality, that didn’t appear to be the case.

But then the Source London one finally arrived yesterday.

A year on…

The last 12 months seem to have flown by, and we are approaching the first anniversary and service for the Leaf. It has covered nearly 5,000 miles as I write this. That is around 500 journeys to work, which seems about right.  After all, this is why we bought the Leaf: to provide a clean, safe, easy journey to and from work.  This it has done with aplomb and has become a valid choice for any journey.

To celebrate, I took it for a bit of run this morning in the -2°C environment to provide that essential service to mankind – picking the kid and his friends up from last nights’ sleep over 🙂

I don’t know if you live with teenagers but the whole ease of 24 hour communication means nothing is properly arranged any more, so armed with a postcode and house number and a fully charged Leaf, I plunged into the January chilled Suffolk Countryside and really returned to my roots.  I was heading to roads I last travelled as a 17 year old in a newly covered (insurance wise) version of my mum’s car.

In those days, I was driving a four year old Carlton 2 litre CDXi where the D stood for Delux and not diesel.  My mum adored that motorcar and as I was then limited to an automatic gear box, this was real freedom and so much responsibility.  I was armed with a map – a Phillips/AA car drivers version with a great spiral spine which allowed easy book marking of the current pages and my favourite mixed tape.  At 10am on a Saturday on the A14, the roads were easy and relatively quiet.

January 2015, I had a similarly colour painted electric car (the Cartlon was maroon, the Leaf is burgundy) and the spiral spine map’s function was being covered by the Google connected Sat Nav, my mum’s car phone by a bluetooth connected 3G smart phone and I was heading over to act as taxi. Very little changes as time goes by.

The biggest shock I have had driving since November has been how difficult it has been to achieve the 12% of battery use getting to work and 14% on the return journey.  De-misting the windows has been the biggest draw although I have found the following tips really help get the most from the lithium ion batteries:

  1. Turning off the LCD screen gets around 4 extra miles from an 80% charge.  This is achieved from Menu->Settings->Display and change the “on” to “off”.
    Hitting the moon/sun button turns this back on permanently and turning off needs the same lengthy procedure.  If you want to flash view the map or battery consumption that will come up for 30 secs and then the display will turn off again – really useful if you need the Sat Nav to show a junction or roundabout layout!
  2. By turning off the “heat” and “auto”, the fan can be used to demist the front windscreen using only the lead acid battery (another 4 miles per 20 kW/h charge).
  3. The lead acid battery goes in to recharge mode (the right blue flashing light on the charging indicator is activated) in the small hours of the morning.  It is worth activating the charge timer to cover this and get back the 2%.
  4. The climate timer is really not happy if the battery charge is below 80%!
  5. Turn back to D mode rather than B when climbing up hills and if you’re really brave, turn off the Eco mode too.  Remember to switch B Eco when going down hill to get the most regenerative charging.
  6. Charging at home or in Waitrose for 30 minutes gives about 10% on the battery charge which works out at around 50p.  An hour gives you 20-25%.  So an hours’ charge covers most of the next day’s run to work.
  7. A garage means you don’t have to waste time or battery defrosting the car.

Today was the first real experience driving on sub-zero roads and snow and the car was beautiful: predictable handling and easy visibility – I made the most of the auto-wipers.  The rear seats meant the passengers were comfortable and the 50 mile round trip was a breeze.  In the summer though, I would not expect that to use 80% of the battery (much closer to 55%), so I was glad I had set up the route before hand while still charging in the garage!

I did find I switched on the head lamps rather than wait for them to come on automatically but that’s not really an issue as they switch off when the Leaf is switched off.

All very nice and informative: what about the power consumption for the year?

In a year, up until 15th Jan 2015, we have covered 4764.4 miles with 1160kW/h or 1.2 MW/h of electricity.  That’s around 4.1 kW/h per mile, which is around 4.3p per mile (at 16p per kW/h).

Even with the recent drop in petrol prices (we have motorcycles and a diesel car so we still notice that) the Leaf provides very cheap motoring and we are not paying for every piece of electricity used to power the car.  Some of it is now coming from our own Solar Panels (958 kW/h have been generated since 23rd August).  That distance, if we’d charged at home and paid for it, the year’s electricity would have set us back £185 (that’s 1160kW/h at £0.16 per kW/h).

The longest single journey was back from London on a charge (est. 124 miles) and I have spent 3.5 hours charging the car at fast chargers provided either by Nissan or Ecotricity during the year.

I still wish there was a fast charger in Ipswich but we’re heading in to London at half term as a family and the Leaf will provide a means of driving that distance which is much cheaper than taking the three of us by train from our home town and comparable in terms of time.  Both forms of transport are powered by electricity, doesn’t the 25 year old train look a little dated, expensive and inconvenient?

I wonder where we’ll go next year with the Leaf.

13516

It is Sunday, 14th December 2014.  13,516 days ago (that’s 37 calendar years to you and me) I received insulin to treat diabetic ketoacidosis as I was diagnosed with type 1 diabetes mellitus.

The expectation at the time was not great: being a girl and before the introduction of home testing for blood glucose, it was hit or miss whether I’d make it to 20 in one piece.

In the early 1980’s, as blood glucose kits became widely adopted things began to change.  Yet, it wasn’t until the Diabetes_control_and_complications_trial was published in 1993 that it was proven that maintaining blood sugar levels as close to a non-diabetics levels would significantly affect the chances of developing complications from long term diabetes mellitus.

Before that, it was guess work.  I was reasonably lucky in that my mum was a pharmacologist and bought my first blood testing kit.  We’d made a decision to aim for normal blood glucose levels as much as possible but the data we’d previously got from urine tests was never particularly meaningful and difficult to make effective changes to my insulin levels.

The early sets of data led to guess work, careful testing, recording and analysing.  Even then it was assumed that women did have a more complicated regime as we had the menstrual cycle, but so little guidelines were provided as I hit puberty and there was so little the research  published in the journals we read.  That’s now changed, thanks to the internet.

As I “celebrated” my anniversary on Friday, I started a new job and was describing my pump and the display on the screen, presenting the readings from the sub-cutaneous blood glucose sensor.  The readings probably suggested my period was due in the next week.  I was greeted with shock that such a fundamental gearing of the human metabolism would affect my insulin requirements.

“I’ve known two insulin dependant diabetics in my career and they were both men.”

First, the plan

It’s definitely Autumnal at the moment, so naturally, I am planning a reasonably long journey with the Leaf.

116 miles in the South of England is not a treck across the Himalayas!

No it is not.  But it is the first long journey I have done in the Electric Car on my own.

It will also be the first time I have used the Leaf for business (albeit training) and to be absolutely fair, I could do this journey in our diesel.  Which would probably be much more sensible on so many levels.

One of the reasons we have the Leaf is to help with air quality: that’s why the UK government is still subsiding this technology.  So, having done the preparation with routes etc, I am looking to do this in the Leaf.

On your head be it! So, what’s the plan?

First leg: Ipswich to Thurrock Service Centre, M25 (that’s just before the Dartford crossing to you and me).

Then on to Chertsey.  Charge that evening at Cobham services.

Return: Leave the hotel and charge again at Thurrock via Ecotricity point.

This time though, I’ll be travelling during rush hour and will take the time to enjoy tea at Ikea, which also has an Ecotricity point, before completing the journey.

Sounds reasonable, how was it in practice?

When you learn Prince 2, you are taught to anticipate what risks can de-rail your plan.  In my case, every charge point has some options in case one doesn’t work.  Where possible, the plan has two points available at each stop or a fast charger within 12 miles.  All I need to ensure is that I have at least 12 miles on the clock.

The exception is Cobham, the nearest one to there is 40 miles away.

So I left Ipswich at 5:40am on Tuesday and headed to Thurrock.  It has to be said, Lakeside’s turning is amazingly quiet at 7am as I turn in to Gray’s services and quickly find the charge points.

It’s the first time I have used the Ecotricity card but the fast charger had the same user interface as the ones hosted in Glyn Hopkins’ Colchester and Romford branches, so I started the process.  I found that with the first charger, my card wasn’t accepted at all.  As this was something I wasn’t expecting, I got in touch with the help number on the card.

Marcus, from Ecotricity, answered my call.  He asked me the try the 2nd charger and this time my card was accepted.  It has to be said that the fast chargers are not the most trivial pieces of equipment I have ever used and it took a couple of goes to get the cable seated and ready to go.  Only to find it had a fault.  Blast.

“How much charge do you have?” Marcus asked.
The range!
“11%, around 11miles.”

 

 

 

 

 

 

 

“Oh, the only one I can guarantee you can get to is 12 miles away and I am not happy to recommend that.  Ikea has a working point but I don’t know if it will be accessible before they open at 9am.”

Marcus very kindly texted over the postcode for Ikea and I headed over.

I knew from my previous research that Ikea opened at 10am and the one at Thurrock has a serious number of gates which are locked while the shop is closed.  I also knew this was probably my best option, so I drove the extra 1.7miles to find the gate I encountered was closed and the deserted car park did have 4 cars parked.  Did that mean a gate somewhere was open?  I headed towards the parked cars and turned towards Ikea as I ran out of road to find an open exit 🙂

I love Ikea, 750am on a Monday
The point is really obvious and within 2 minutes of parking, I was recharging with enough to get me to Chertsey and back to Cobham.  Time was now the big worry.  As was keeping warm – I had remembered my mobile so set the heater on while I charged and dealt with my planned toilet break thanks to B&Q and bought a planned item as a thank you.

Did you make the meeting?

Absolutely, with 20 minutes to spare.  The experience did mean I made the effort to charge the car that evening.  Cobham worked beautifully (well, one did!) and that meant I could return to Chertsey for the remainder of my course and get back to Thurrock the next day.

And home again?

Again, I returned to Chertsey and spent 12 minutes getting the charge up so I could make Thurrock and travel at an average of 60mph (traffic permitting).

As per plan, I headed to Ikea.  While one space was occupied by a petrol driven Merc’ the other was available and I started the charge and headed for food.

I had a comfortable meal, toilet break and wondered around and return to find the car ready to go and a 2nd Leaf driver ready to start their charge.  I found they were heading to Peterborough and would get a 2nd charge from Cambridge.

This stop enabled me to get back home easily.  The entire journey took just under 4 hours including the queue for the Dartford crossing.

Would you do it again?

Yes, not least because this allowed me to claim expenses and the company has not caught on to the fact that EVs do not cost as much to run as ICE’s.  The single claim more than covers the electricity for the quarter we have bought for the car and the charge for the SourceEast card.

A journey of a 1,000 miles

begins with one small step.

Today is a beautiful Autumnal day in the East of England.  Last Friday, my family and I finished the final stage of a flight from Cape Town, ZA to Heathrow Airport, UK and finally the last lag home.

Not an environmentally friendly trip, but over the past three years we’ve travelled to Europe by car rather than aeroplane for our holidays so we don’t increase our carbon foot print more than we have to for this special journey.  It was incredible, if you get the chance, South Africa is an amazing country.

So, you took the Leaf to Heathrow?

Unfortunately, I lost the distance argument.  Seriously,  I believe the Leaf would have breezed the 111miles from Heathrow Terminal 5 to our place.  We travelled outside of rush hour, so kept a constant speed the majority of the way (roughly 67mph on average).

I think we could not only have made it there on one charge but it would have been as convenient as taking the diesel.

Here are the sums 🙂

Our road to Heathrow Terminal 5 = 111.86 miles (as the car drives or rather Google Maps and Nissan’s zero emission route master).

So that’s only a maybe.  Looking at Zap-map and the various web sites the obvious thing to do is fast charge at South Mimms going to and returning from Heathrow.  It has to be said at this point, South Mimms services has no mention of having a charging point on the South_Mimms page!

So, home to South Mimms is 81 miles approx.  Allowing a 100% battery to get us there at an average of 60mph.  On a good day that should take us 90 minutes.  As I have a Ecotricity card, we can charge there for free.

From there, onwards to Terminal 5, another 30 miles.  We can charge here for free if we need to but that charge would need to be done while we were through security, potentially, as it is a 3kW charger.

Or we could leave the car, while away on holiday and come back to a car which will almost certainly need a 30 minute charge before getting back to Ipswich or even South Mimms.

The closest fast charger (CHADeMO), to Heathrow, seems to be the Moto Services on the M4 Junction 23.

That would give us a fair 95% in 30 minutes – so we could make it all the way back to Colchester (our nearest fast charger).

In short, going there:

  1. Leave Ipswich with full charge
  2. 80-90 minutes later have a 30 minute break 90 miles from starting point, 95%
  3. Park at Heathrow normally.  Total journey time approx. 2 hours and 50 minutes.

Coming back.

  1. Leave Heathrow with 50% charge.
  2. After 10 minutes, charge for 30 minutes, giving approx 95-97%
  3. 98 miles later, park in the centre of Colchester and fast charge to 80%, 30 minutes.
  4. 16 miles to home.  Total journey time, approx. 3 hours 20 minutes.

What would have enabled this journey to be a guaranteed choice?

Let’s face it the Leaf would have got us there, we just weren’t willing to make the choice.  We did discuss what would have made it an immediate yes rather than a no for where we live in the country.

A single step would do that: charging points every 60 miles along the major routes, e.g. all dual carriage ways and a fast charger every 120 miles.  It’s beginning to come, in large thanks to Ecotricity who are installing many of the fast chargers at service stations along the major routes.  This is a completely free service, which is amazing.

(Personally, I think a fast charging point at the junction between the A12 and M25 would have sealed the deal, even a paid one.  This is currently a void, the nearest one in Romford, within the M25).

UK rapid charging points Nov 2014I say 60 miles as a 3/7kW charge point, the Leaf seems to get about 10% in 30 minutes (remember the trip back from Colchester) which if you are driving carefully and getting something back on the regenerative braking that would allow you to to ensure you had an extra 12-18 miles.  The 60 mile distance then ensures you have opportunities to get enough to get to a quick charger if you stick to the UK speed limits.

When we bought the Leaf in January 2014 there were only 146 fast DC chargers available in the country and few public charging points in East Anglia.

Since then the numbers have grown in the UK.  There are 490 rapid DC chargers sited throughout the UK today and 210 AC ones.  Nine of these rapid charging points are in East Anglia including Bury St. Edmunds (9am-5pm most days) and just past Cambridge on the services bridging the A14 and M11 (this is really new, the last time we looked at going to Cambridge we had few options of getting back to Ipswich on a Sunday).  This really opens the country up for the Leaf.

What seems to be happening on the A12 and A11 is the adoption of “Charge your car” pods.  This works by attaching a credit card to the account allowing a fixed price per charge.  The charge is only collected by “Charge Your Car”: the pod owner actually gets the cash.

The most common form of pricing for these is a fixed price per charge no matter how much electricity you use or time you spend occupying the point.

A fixed price per charge is fine if you are charging from 0-80% but not so good if you only need an 10% to get you home.  This something I have used on longer journeys because that is only 8 minutes on a 50kW DC charger.  £5 is a high price for 10 units of electricity (retailing at £1.60).  There is much debate on the forums about how this should work and compared to petrol which is governed by the weights and measure act 1985 this seems to be an unregulated market.

As per the map above, I am really glad I don’t live in North Wales or North West Scotland.  Outside of the M4, there doesn’t seem to be much interest in providing the infrastructure for the Welsh despite a reasonable population size.  I am not sure what the population of North West Scotland or whether that’s reasonable.  The Isle of Harris looks good though 🙂

Part of me wishes I lived in Northern Ireland.  All of their points are free and within the magic 60-80 miles.

In fact, while we were discussing it, I’ve noticed that my husband could easily take the Leaf down to his office in Woking the next time he has a meeting: there’s a new fast charger on the M25 at Junction 9/10.  Thanks Ecotricity 🙂
