Dear R-EV enthusiasts

Electric quad bike

Welcome to our Christmas newsletter!  For this issue we are down on the farm.  We have been driving the first of our electric Land Rover conversions designed specifically for farmers through the legendary Worthy Farm mud, and we bring you news of one of our partners:  Off-Road Electric.

This year, our Christmas charity has been elected by one of our customers, Nick Hooper, who has staged a one-man on-line concert for Justice Defenders.  Nick’s concert can be found on YouTube here.  Nick, being a lovely man as well as a celebrated composer, has written a piece of music about his electric Morris Minor, and you can hear it from minute 13:40 in the concert.  It’s a catchy tune and is getting a lot of attention!  Please consider making a donation to Justice Defenders, which you can do here.

So, off to Worthy Farm…

Cow-Powered Electric Land Rovers

electric Land Rover at Worthy Farm

Those of you who follow our social media will know that we have won an Innovate UK award, together with Cardiff University and Worthy Farm.  The scrutiny process for an Innovate UK award is tough and we are really pleased about this recognition of our technology.  Full details can be found here.

Cows contemplate an electric Land Rover

We will be building four full-instrumented electric Land Rovers for six months of trials down on the farm.  The first Defender was delivered a few weeks ago, and we have been spending happy hours driving it around on cow-power.  All the electricity at Worthy Farm is generated by solar power and an anaerobic digestion power plant working on the dairy farm slurry – so the Land Rovers will be using 100% green electricity.  As you can see in the picture above, the cows seem pretty happy about it!

The point of the project is to gather real data about how Land Rovers are used on the farm, understand the demands on motors and batteries and whether there are extras that we can design-in, to make the vehicles better to use, as well as zero emission.  The challenge is to design down to a spec, to make electric conversion kits for farmers as economical as possible.  The vehicles are instrumented up to the gills, and we are beaming the data real-time to Cardiff University, who are building a computer model to predict how the electric Defenders will perform on other farms and in other environments.  What have we learned so far?  Pulling a loaded trailer up steep muddy hills creates tremendous voltage drops, and our electric Land Rover is really popular with the farm workers: it is fast, but most importantly its heater is instantaneous!

The spec?  This one is simply a NetGain Hyper9 motor connected directly to the clutch, so all the gears and the hi/lo ratios are all intact: simple, low-cost and an exact match for the outgoing diesel engine.  We have other combinations in the Works though, and will keep you in touch with what’s going on down on the farm!

Off-Road Electric

We are delighted to announce a partnership with Off-Road Electric, a company dedicated to bringing zero-emissions to working landscapes.  Electrogenic is using its expertise to provide servicing and back-up to Off-Road Electric and its customers.

There are some serious work-horses in Off-Road Electric’s product range – witness our very own farm-boy Jake looking happy on a shiny new electric tractor.  But to be honest, some of the vehicles make pretty good toys too..

The Lithium electric quad-bike has a bigger range than its petrol equivalent.  You can sling a sheep on the back and make it back off the moor though the snow-drifts quietly, cleanly and efficiently.  Go on, you know you want to…

And welcome to… Marc!”

Marc is the owner of Off-Road Electric.  He runs his business in a hands-on sort of way, though we don’t know if he has personally tested the roll-bar on his quad-bikes yet!

And finally…

Our favourite link of the season is the Blob Opera.  Click here for the most seasonal fun it’s possible to have on-line.

And if you are clean out of Christmas present ideas, and  live locally, The Village Refill (proudly sponsored by Electrogenic) is making its last delivery tomorrow.  If you don’t live locally, you will just have to buy one of Marc’s electric quad bikes.

That’s it from us for 2020, a busy year despite the challenges. Lots more electric car conversion news coming in 2021.

Electrogenic October 2020 Newsletter

Dear R-EV enthusiasts

You say you want environment and you want cars, so this month’s newsletter is a bonus:  two lead articles, and both of them are about cars and the environment.  We are proud sponsors of The Village Refill, who are local and who entrusted us with the re-powering of their 10-year old Mega electric van.  Also, we get lots of questions about hydrogen and its potential future in transport.  It’s a big subject, but we have accepted the challenge of giving you our take on it in four pithy paragraphs.

We are still looking for new staff, so please help put the word out: the clocks have changed but the lights are still blazing in the Electrogenic workshop and we could do with some more help!  And without further ado, welcome to October’s newsletter!

The Village Refill

Village Refill's Mega van

This month we had an unexpected visit – a 10 year old Mega van.  What’s a Mega van, I hear you ask?  It’s perhaps the distant ancestor of the Citroën Ami (?!) – it’s French, it’s 99% plastic and it’s certainly eccentric.  It has been driving around a campsite in Yorkshire for the last ten years, but now it is proudly owned by The Village Refill, and needed an upgrade to deal with the rigours of Oxfordshire tarmac.  The Village Refill is a brilliant enterprise, creating a local circular economy to eliminate single-use plastics from every-day household items like washing up liquid and shower gel.  Unfortunately you will only be able to access their fabulous products if you live within range of their Mega delivery van, but at Electrogenic we’re working on that…

The Mega is an EV pioneer, using an old 48V DC brushed GE motor and 12 lead-acid batteries.  As we discovered, it also has a cunning colour-coding system for the control wiring – all 30-odd wires are white – a control system logic that, well, defies logic and a charge lead that looks like the plug on our works kettle.  What The Village Refill needed was the top speed lifting above 28mph (downhill with a following wind), and improved range so that the delivery radius could be extended: if you are running a new eco business, you can’t have your products delivered by fossil fuels.

So what did we do?  Firstly we agreed to sponsor The Village Refill because we think they are fantastic (spot the Electrogenic logo in the picture above) and then we got to work.  We pulled out 360kg of lead acid batteries and repurposed them as storage for solar power in a narrow boat – thus reducing local diesel emissions.  We replaced them with 2 x Tesla Model S batteries (yes – a Tesla-powered Mega!), we neatly bypassed the Mega’s antediluvian charge system by adding our own, and we added one of our range/economy screens in the cab.  Along the way, we made the van 300kg lighter, fused the workshop electrics by pulling the kettle-cord out of the van before switching it off at the plug, and created our own James Bond moment.  When Maya came to collect the Tesla-Mega, we had just test-driven it and managed a flat-out speed of 14mph.  What was the problem?  Aha!  The motor controller thinks there are no batteries so it is speed-limiting to enable the van to get to a 13A socket.  What to do?  Logically, there are only two (white) wires that it could be, so we need to cut one of them…  Snip!  You could almost see the detonator clock stop at 007.

From this
To this!

Did it all work, I hear you ask?  Yes!  The Tesla-Mega is now happily zipping around Oxfordshire and it can keep up with local traffic. It’s cheeky and cheerful and doing The Village Refill proud.  So if you’re local, click the link, do your bit and smell great (we particularly recommend the shower gel).

Hydrogen powered R-EVs?

operation of a hydrogen fuel cell

We are often asked about whether our R-EVs will ever run on hydrogen fuel cells, rather than batteries.  The short answer is “we don’t think so”.  It’s a complex subject however and we will try to unpack it a little here.

A fuel cell works much like an electric battery, converting chemical energy into electrical energy.  The hydrogen “fuel” combines with oxygen from the air inside the cell, generating electricity and emitting water vapour as a waste product.  In a car, the electricity can be used to drive an electric motor…and you know the rest.

The big pluses for fuel cells in electric cars are a) you can refuel quicker, and b) you can reduce the weight of the vehicle.  The big minuses are that hydrogen “fuel pumps” are not trivial pieces of engineering (think explosion avoidance) and as charge-point infrastructure improves and using EVs changes people’s habits, the need/desire to drive to a filling station to refuel reduces.

Hydrogen is also structurally more expensive than batteries.  Energy is not free, and the electricity-storage-electricity cycle for hydrogen is less than 50% efficient, compared with about 85% cycle efficiency for batteries.  Hydrogen technology is improving in efficiency and cost effectiveness, but so is battery technology, and hydrogen is starting from behind.

Fuel Cell EV lifecycle impact

This diagram is from research presented in Applied Energy.  It shows Fuel Cell Electric Vehicle (FCEV) and Battery Electric Vehicle (BEV) ownership cost and environmental impact, compared with  Hybrid Electric Vehicle (HEV).  The analysis concludes that battery EVs have a lower ownership cost and environmental impact than fuel cell EVs.

Where does the hydrogen come from?  At the moment, about 98% is produced from natural gas, with carbon dioxide as a by-product, and only a tiny fraction of that is used in EVs (it’s mostly used for making fertiliser).  We don’t have enough renewable energy to supply our electricity needs as it is, and the electrification of heating and transport will increase demand even further.  Increasing hydrogen usage therefore means increased use of natural gas (and hence CO2 emissions) in the short to medium term.

So will hydrogen be used in transport?  Fuel Cell EV technology (FEVC) could be useful for commercial applications where bulkier vehicles need to travel long distances, carry heavy loads and refuel with minimal downtime.  Road and rail bridges have weight restrictions and fewer/lighter batteries means more carrying capacity.  But for your R-EV?  We don’t think so.

Mystery Picture 14

Answers from September:

Mystery Picture 11 – it’s a Citroën C5 hydraulic pump for the hydro-pneumatic suspension system.  In the time since we took this, we have modified it, cauterised its brain, added a control system, fitted it into the Citroen DS and then driven it around with a petrol engine and electric suspension.  And it rides beautifully.  So now the engine is out and we are pressing ahead with the conversion of the drivetrain to match.

Mystery Picture 12 – the 12V DC-DC converter, charger blades, BMS, charge system and 12V system all ready to go into the eMini – which is sadly now back with its owner (we love that car).

And welcome to… Jake!

Jake is our new apprentice.  He comes to us all the way from a cattle station in Western Australia.  As Jake says, he has been searching the world for his perfect job, and now he has found it a Electro-GEnic!  Jake is studying at the Heritage Skills Academy at Bicester heritage and comes to us with some pretty mean welding skills (he made Mystery Picture 14), and boundless enthusiasm.  You can see examples here and here!

Electrogenic August 2020 Newsletter

Morris Minor Electrogenic banner

Dear R-EV enthusiasts

Like many of our readers, at Electrogenic we have spent August dodging storms and quarantines, and confirming once again that the place we like to be best is in the workshop!  We have also been listening to reader feedback, and lots of you want to hear more about some of the cars we convert.  “Snowy” the Morris Minor has been drawing adoration in our social media, so we thought we would tell you a little more about him here.

It has not just been all about the workshop this month, however.  We have been putting together some exciting new initiatives, including an electric drive system for boats, with all the usual Electrogenic bells and whistles.  So soon you can be Powered by Electrogenic on the water, too!  More of this and other developments in the coming months.  And in the mean time, have a great August Bank Holiday.

Snowy

Snowy the Morris Minor (named after Tintin’s irrepressible dog) has seen 51 August bank holidays so far and as you can see, he looks forward to the sunny country lanes of his native Oxfordshire, cruising with his hood down and a gentle summer zephyr in his owner’s hair.  We’re hoping he won’t be disappointed this year..

The Morris Minor was launched at Olympia in 1948, and was assembled at the Cowley works in Oxford from 1948 to 1971.  In its day, it was radical.  It had no separate wings or running boards (unlike its contemporary, the VW Beetle, for example), it had a unitary body, and in an optical tweak, it had small wheels to make its relatively small body look bigger.  Under the bonnet, it was no less radical.  The engine was positioned over the front wheels instead of well behind them: investigation and experimentation having proved that the weight of the engine in this position dramatically improved the stability and controllability of a car. The front wheels themselves were given an advanced torsion-bar independent suspension, which combined with the rigidity of the unitary construction body, gave a standard of ride comfort such as had never been experienced in a small British car before.

And the Morris Minor is still going strong.  It is cute and sturdy, and though it was not an original feature, the cabriolet top creates a lovely car for zooming around in the sunshine.

So what are we doing to Snowy?  Snowy’s owner doesn’t want gears, and those small wheels are a help:  they make it easier for us to match an electric motor for direct drive without needing a reduction gearbox.  The new setup uses the original brass bush that secures the drive shaft at the gearbox end, and Alex has designed a coupler to directly connect this to the motor.  This part is designed in-house but produced out, and when this arrives next week, we will start the build.

Snowy generally does the school run and weekends, but also needs to go to Wales occasionally, so we are fitting 6 x Tesla model S85 batteries, for a total 33kWh.  A car of his size and weight will do about 4-5 miles/kWh, so this should get Snowy comfortably to Wales.  This also means a nominal operating voltage of 135V, which means we will be fitting a high-voltage motor controller to suit.  The batteries are mounted in our standard modular boxes: four in the front, and two singles in the back.  There is room for more batteries in the front, but the front suspension on a Morris Minor is famous for failing if the king-pins are not regularly greased, so four batteries means that Snowy is slightly lighter in the nose than before.  Two single batteries in the back means we can fit them in without cutting the floor – always a no-no.

Transmission connector for Morris Minor

We have checked Snowy out, he is in excellent running condition and the addition of regenerative braking system will help him stop even quicker.  We will re-purpose the fuel-gauge to show charge, but also install our standard wireless display which (among other things) shows battery charge and how heavy the driver’s foot is.  Snowy will also receive our electronic vehicle management system and we will add heating and headrests to the seats, for comfort and safety on the winter school-run.

Keep an eye out on social media in a few weeks for eSnowy!

Mystery Picture 9
Mystery Picture 10

Answers from July:

Mystery Picture 7 – it’s a universal public charge point!  This is one of Steve the Whizz’s creations:  it impersonates every different sort of public charge point in the UK, so that when you drive up and plug in, our on-board chargers know every funny “handshake” they need to, to ensure you can just plug in and go off for a coffee.

Mystery Picture 8 – they are LTO batteries, but where they’re from, we’re not sure – so perhaps you can tell us!  They came out of a huge battery pack flooded with silicone fluid and capable of providing some 2000A constant at some 600 volts. Their use is shrouded in mystery but maybe a starter for jet engines?

And welcome to… Oli!

Oli is a fantastic motor mechanic who has joined us to pursue his passion for innovation and doing new things, and who liked us, because apparently we “know how to put a car together”.  Oli has a long experience of doing cool things to classic motors.  He adds another production “line” to our workshop, to help us convert more cars, and also brings a keen eye for detail.

Here, he is building a jig to create Mark 2 of our classic mini front subframe.

PS. Oli hates having his photo taken, but it’s one of those rites of passage things at Electrogenic..  Sorry Oli!

And finally…

The video link in this month’s newsletter is the BBC’s programme for the 100th anniversary of the Cowley Motor Works, where the Morris Minor was assembled and the marvellous mini was created… of which more next month.

Our Covid-appropriate test-drives are going well – lots of happy smiles all round.  So if you fancy driving a Retro-EV, give us a call.  And we will be at Bicester Heritage from 18-20 September for the Classic Car Drive-in Weekend.  So see you there!
