Classic EV Conversion - Daimler 250 (V8)

Post by Daimler » Mon, 13 Nov 2017, 08:36

Hello to the Forum.

I drive a 1968 Daimler 250 V8 almost identical to this one:https://www.shannons.com.au/auctions/20 ... BN179LAE5/.

At least I did until recently when the engine finally died.

Rather than jumping into replacing the motor with something the same or similar, I thought I should at least explore the feasibility of doing an EV conversion.

The car has a kerb weight of about 1300kg (with the current engine).

I am entirely new to this and suspect it may be unrealistic for me.

If anyone has the time and knowledge to answer a few questions I would be sincerely grateful.

1. I am reasonably handy but not a mechanic nor an electrician. (I can build and fix things.) How much of the work could I possibly do myself?

2. What kind of a set-up would you recommend? I’d like to have a 150+km range if possible and some get-up-and-go?

3. Could my existing automatic transmission marry with the electric motor?

4. Is there a DIY manual/job list for doing a conversion?

5. What about things like powering the existing power-steering, providing a de-mister for legal requirements, and any other bits and pieces I would need to know about? What happens there?

6. How far would a budget of $10,000 go?

7. Approximately how long would this kind of project take? (I need to get back on the road ASAP.)

8. I live in Toowoomba, QLD. Is there any local enthusiast who might like to guide/help/become my new best mate?!

I look forward to any feedback anyone can give.

If you are just laughing and rolling your eyes and want to tell me to forget about it, that’s fine too. I need to know.

With sincere thanks,

Daimler

The weight is not really any different to a new 4-door sedan.
The issue may be Gross vehicle mass (GVM) - which may not even have a listing for your car.

I am sue if you cant there maybe some that can - go to the AVEA meeting as suggested.

150km may mean you need a 30kWh pack which is quite large for a conversion.
The original 2.5L V8 had 106kW (supposedly) so there should be a few motors and controllers to choose from.
An 11" DC system would probably be fine.

3. Could my existing automatic transmission marry with the electric motor?
It could but isn't usually worth the effort.
More common it to ditch it and have a custom drive shaft for direct drive.
Less losses and less to go wrong.

Ah NCOP14 would be a place to start otherwise keep asking questions here.

So usually it is the case if it had it before it should have it after.
You'll also need a vacuum pump for the brakes.
Either replace the power steering rack with an electric one or fit an additional motor to the pump.
A water heater and small pump can be placed in the engine bay to keep the interior heated.
Or gut the vent unit and replace with a ceramic air heater.
Traction Fuses, contactors, BMS are some other parts.

Not far.
If your lucky that might get you 25kWh of batteries - that's 5kWh less than your desired range.
Wouldn't include anything else :shock:
You'll need like $6,000 just for a motor and controller.

Well if it's like me and have a million things to do - for ever :lol:
If you were dedicating 100% of your day to it perhaps 3-4 weeks.

No I think it's worth it.
It's all possible - you just need the Mula and time and a willingness to do it.

Easier with a classic;
If there was a Daimler 250 model without fancy things like brake booster, power steering, heater/demister then you can hopefully do without them to reduce complexity.
Take a look at the converted cars at the Brissy meeting; similar (front engine + RWD) layouts would include Weber & Coulomb's MX-5.
