Classic EV?

I know there was a guy on here that was putting an electric motor into a C123 in Perth a few years ago.
Does anyone know what happened to that?

There are a few companies in UK, USA etc that are putting electric motors into classic cars (VW Kombi, Range Rover, Fiat bambino, BMW 2002, etc).
Is there anything similar here in Aus?
it might be time to consider how to keep our old cars when the world has gone electric...

Don't hold your breath.
By the time of electric vehicles we will be long gone.

F.W.I.W. I met a battery company guy a few weeks ago. He was driving a Mercedes Benz C300e - e for electric.

There is are a few companies in Perth that sell all the parts to convert just about any vehicle into an EV.

A mate of mine converted a Hilux ute into an EV.
The guy from the shop convinced him to remove his gearbox.
I argued that having a gearbox has so many advantages, mostly the ability to cope with reaction forces and being able to change the speed range.

He went without the gearbox, and it resulted in an extremely fast acceleration and not much of top speed or action radius....

It's fairly easy to power the car with an electric motor, however getting the auxiliaries to work is far harder.
You now have to find an electric driven power steering pump, aircon, vacuum pump and a few more...

I noticed on the road today a van with EV car 24/7 Roadside Assist.

So it looks like old and "new" technology all have some similar problems.

I have a carry van ev and am working on a 91 rx7 savanah (not quite vintage rego ready yet) both with lithium packs 18000 and 38000Ah respectively. The rx7 has advanced magnetics 9.1" dc motor (2k) 1000A controller (1.6k) at 144V it has about 410Nm of torque from standstill so should be good range and very fast whereas the carry is light so decent range too if I go slow (best to do so anyhow given the handling and the drag coefficient is bricklike) and it's a bit more useful for missions. I have a friend who wants me to do her Austin A40 1950 ute so I have a Nissan Leaf battery pack re-purposed for that brewing up too. None of the donor vehicles ran and were very cheap. Looking forward to no hoses, plugs, filter, oil, coolant, exhaust, heat, sound, fuel and having one moving part in the motor. Seems like a no braner to me now we have the batteries we always dreamed of and stuff like graphene supercaps in the wings. the EV age is here already, in 20 years no more production of i.c.e and 20 years after that no registering them either, that is the plan. I want to do a porsche 924 martini that has been on the backburner for a few years next because it is the most fun to drive of any car ever in my experience and with gobs of silent power it will be awesome. My mercs I love but they are a bit heavy (therefore high rolling resistance) for good range as an EV but aero mods are incredibly effective. I paid 10k (now it's get-able for 6-ish like the 120V of leaf cells the carry got) for the big battery pack but that should do at least 20 years and pay for itself in two. (I burn a bit of fuel out here in the country.)

To the advantage of old classics as nicer looking donors is power steering and heaps of wiring is not necessarily as much of a feature as with modern cars so a simple glorified golf cart is adequate simplicity. What you need other than the (2-3k) motor and controller is a 12V vacuum pump and reservoir and vac switch to make a light come on to tell you the brake booster is not working for a lack of nothingness, an emergency cutoff big red button nearby for freaky stuff, 12V hairdryer for demisting, g-force activated cutoff switch like for airbags for the chunky relay you need to shut off in case of an accident, big orange coloured cabling so if you crash the rescue guys know what not to cut, a few simple interlocks so you don't turn on the key with the accelerator down or drive off with it plugged into the wall, a pack voltage to 14.2V DC to DC converter to be your alternator impersonator, otherwise watch you don't go too heavy or shift the weight too far, make sturdy battery boxes and do good electric wiring and install a battery managment system to balance the cells and you have the current national code of practice for alternatively powered vehicles (NCOP14) covered in a nutshell, about 800 bucks to engineer it and you are away. Vintage modified club rego on the log books 46 buck including insurance. about 3 bucks to fill up for your 250k range or less off peak or free if you have waste composting preheater woodchip and lawn clipping powered solar parabolic rankine cycle sterling engined compound steam engine heat pump peltier diode, syngas biochar generator setup like I use in my dreams you could distill ethanol for fun and profit with the waste heat from the shower and use your urine to power a tesla wall and save the earth at the same time. In america the government gives you an 8000 dollar rebate when you register an electric car but now I am dreaming... Thanks to EV works in WA their side has charge points up and down for years already we in the east are far along now too.

Mighty Boy EV.com - a conversion from few years ago but a good read.

I've gotten excited about EV conversions many times and stayed up late through the night trying to convince myself it would be worth it, but every time I come to the same conclusion - all the gear is too expensive at this stage for a car I dont drive often enough. Thanks for the comprehensive checklist though!

$10k for a minimum-requirement battery.
$3k for a decent motor (in Aus)
Another $2k for vacuum pumps, wiring, plugs, misc..
A lot of fiddling around (the fun, but time consuming part)

As much as it is the dream to leave the traffic in the dust, with only the sound of the wind and the squeak of the suspension, its still too expensive to justify. Until we get some electric cars being sold in good numbers, going cheap second hand or written off by insurance companies, I dont think we'll have cheap parts for a long time yet. I like the way you think though!

I appreciate this thread - thanks to all who have contributed.

Here is a curly MOD Squad request - all and any replies welcome.

As someone who is NOT particularly mechanically minded but LOVES my Mercedes.....I'm trying to balance a "LET US NOT":

1. Knowingly contribute further to global warming if we can avoid it' (it being a clear existential reality unless you've got your head in a vat of sump oil or think Tony Abbot or Donald Trump are rational human beings)
2. Allow beautiful classic Mercedes to leave the road simply because they were built in the era of "What is a greenhouse gas? Is that when my indoor plants breaks wind?" I'm a huge fan of Merc design/aesthetics and engineering quality - let us not allow them to diminish their presence on the road!
3.Contribute to the multitude of non recyclable 'plastic rice bubbles' that pass for a 'motor vehicle' on the road today by buying one for a 'daily driver'.
4. Spend an inordinate amount of my weekly wage on motor vehicle fuel costs.

The above are aspirational principles. It's a tight spot I find myself in I know. To make in tighter I only want to drive old Mercs. And I only want a Merc as a daily driver without a significant carbon footprint ("You may call me a dreamer")!

Dreams:
1. I've investigated the OM617 in a W123 as biodiesel option - but haven't been convinced this is a good way to go given the availability of biodiesel and the potential impacts on the vehicle.
2. I've fantasised about an EV conversation to a W108. This is my favourite Merc chassis!! If it could work it would be ideal and a car 'for life'. But the cost!!

Reality:
1. I've a W123 230E on dual fuel as my daily driver - ticks the economy, carbon footprint, and style categories. Good for now.
2. I've also a W123 diesel (300D) I'm about to put back on the road. Could go on biodiesel - but I don't know enough to know if this a a good idea/really possible.
2. I've a W108 shell that could take any power plant that will fit. EV is the fantasy.

In summary - I'd prefer to spend $30K + on a classic modified Merc as a daily driver that I can pass on to my kids rather than buy a plastic rice bubble as a daily and have a 'purist' classic Merc I only take out on weekends or occasionally to club meets.

All and any advice welcome. Anything from outrageously divergent eco-views to outraged petrolhead fundamentalism is welcome.

Any takers?!

Making BioDiesel is a very straight forward process and made to a high standard by filtering and washing, the OM617 will operate with little impact. I have been doing it for 10+ years now.

However, am interested in the W108 going electric. That would be classy.

Lots of comments about the cost being prohibitive.
The way I see it, the 20K or so for a suitable EV conversion is still much cheaper than buying a new EV (whenever they might become available here).
And probably significantly less for many years to come.
And get to keep the car we love (without all those little NLA parts we love so much - VCV LOL)
But obviously I'm not a purist collector. Sale of good working engine etc might reduce costs further.

I was talking with a company that does truck EV conversions. They said come back at the end of the year when they expect it to be far more affordable.

Indeed.
But faulty prius or any factory made and certified road legal EV will have some resale value. Reasonable expectation by all buyers of new EV's
Homemade EV 10x better made than any Tesla or Prius will have limited resale market, close to 'several' people whom understand/understood the conversion.
Until mods become PnP kit that any Billy Bob can work on... all the money placed in the EV classic will be stuck close to indefinitely.
But the fun would be immense and no one with available resources and willpower should be discouraged from these conversions, as long as expectations are set to be realistic.
just my tupence

Nice - thanks - pm'd you for a quick chat - could use some education!

Agreed. Realistic expectations are needed. The little research I've done indicates a W108 EV classic conversion is possible - but there are conflicting views. One issue seems to be the weight of the vehicle vs power/distance of current EV setups. Balance this against EV tech developments and there could be a bright future. I personally don't care about resale value. If I did this, I'm driving it until I'm doing a "Prince Phillip". Must say I'd prefer to be driving a 108 EV than any Tesla or even a modern EV Merc! No comparison - style is style - and its peak was back in the 60's-80's (call me old fashioned...).
