WANTED-Smart 451 ED3 Electric Drive parts

[Geeman]

Hi,
I am looking for Smart 451 ED3 Electric Drive parts for my project -
Vehicle wiring loom LHD or RHD
Charge inlet port 1Ph or 3Ph
3Ph 22kW charger and mounting parts
Any internal HV battery parts or a duff HV battery
SOC/Power gauges
If you have other ED3 parts that may be of interest - try me.
UK based.
George

I would forget about to the smart as hard to get and seemingly a night mare of a system. I would just buy a Zoe as they are more available and better understood

Thanks for your input on this.
Yes,I take your point that the system is a bit of a challenge but it works well when it is ok. I've been working with it for ~ 18 months on and off.
It seems to be well understood in Germany and elsewhere in the EU but it is expensive for some parts and Powertrain/BMS ECU programming has been monitized therefore information is restricted, I am getting there little by little and learning as I go.
I just need more parts for spares and experimenting with, the main problem is there were only ~ 200 451 ED3s sold in the UK so not many parts in the s/h market, hence this parts request on the forum.
It is my understanding (I have not really looked into it) that the Smart 453 Electric Drive is based on the Zoe system, if possible I hope to build a Smart Roadster based two seater using it, there are lots of 453 EDs in the UK market.
Regards,
George

Not 100% sure how similar but always though they both use continental drive train parts , Zoe uses it chameleon chargers and smarts use a 22kw brusa. My only sugestion is have a quick look on facebook for ev clinic , he did some repairs on the smarts and hadn't any nice words to say. I would just suggest moving to a reusable platform as it's hard to get one smart never mind two if you run into issue or need parts. But up to you of course and there seems to be others working on the Zoe drive train re-use.

Thanks for the link to EV Clinic, I don't do social media but I have found the You Tube channel /web pages associated with it. Some of the issues raised sound similar to the 451 ED3 issues which occur if you leave the car undriven without disconnecting the 12V battery.
I'm not sure what you mean by reuseable platform but I agree a more popular system have more parts available, I 'll stick with the Smart equipment for now.
I am in the middle of repairing a Brusa 22kW charger to replace the standard 3.6 kw Lear unit for my ED3 drivetrain but they are expensive to buy even when broken but the rapid charging possibility on a small battery is attractive.

Did you ever progress on this?
I want to do the same thing, I already have my Roadster stripped down to the bare chassis and also have a donor ED3.
But I've been cursed by good luck: The Donor ED3 I got for 2000€ has a really good battery, still has TÜV (MOT in UK) for a year, is generally in an exceptional state and best of all the previous owner lets me drive it and still pays for the insurance. So I'd be mad to teardown a perfectly fine ED3 where I only have to pay the Energy, which is basically free thanks to a large PV.
My main issue is the Battery. in order for it to be road legal in Germany I have to use the ED3 components 1:1 and I cant place the battery under the car like it is in the ForTwo.
I think that it could fit where the tank used to be in the Roadster, but I have yet to try that.

Hi,

The short answer is yes and no, . I decided at that time to continue using the ED3 parts (rather than 453) for the 452 roadster conversion as I had the experience of working with them with my own 451 ED3s, both had HV battery issues when I bought them (usual issues BMS codes set, defective current sensors,cells at 0V.) Both have been running well now for few years and are great fun to drive especially with the Brabus firmware and paddle shift. I then fitted the optional 22kW Brusa chargers and this makes a big difference from the useability point of view as with a short range (60 miles) rapid charging is essential. Fast DC charging is what I am looking at now for the ED3s .

Sometime ago I acquired a 452 rear subframe/axle for sizing up purposes as I have a complete running ED3 subframe and transaxle in the workshop. After laying it on top of the 451 ED3 system I could see it could be made to work although the 452 subframe is a lot shorter than the 451.
Recently I purchased a non-runner 452 (gearbox issues) and an accident damaged 452 (bodyshell damaged) with the view to create a running car to drive for the summer and a body jig (rear half) in order to create a battery box that fits into the fuel tank cavity.
This is where I am at at the moment, the 452 on ICE is running and is fun to drive but fitted with the ED3 powertrain and 20-30kWh of battery it will be even more fun.
How to get this installed,keep the weight down, evenly distributed and road legal that is the challenge.
I intend to keep the ED3 BMS,CMS, etc. but not the cells, I don't know how much battery capacity can be stored in the fuel tank cavity yet but I doubt it will be 20kWh, the front trunk will have to be sacrificed.
AFAIK here in the UK the 452 subframe cannot be altered in any way (no welding or drilling of holes etc.) in order to get any kind of approval and I think there is a way to do this, this winter is when I find out. The plan (!!) is to have it running for next summer.
Personally I would not breakup a running ED3 to convert a 452 as I don't think the OEM battery or cell modules will fit physically into the 452 but who knows till you try.
IMO find another non-runner ED3 with a defective HV battery or at least the the HV battery shell for sizing up with your bodyshell.

HTH.
