Hi all,
Great advance here, almost connecting cables now and we will start testing soon. Adding some pics. Our big concern now is the AC Compressor. We bought the Nissan Leaf one but with the board broken, so after trying to fin the way how to bypass this (pwn DC-AC 350V to 3-phase, almost impossible). We are nos searching for the cheapest way to have AC. This is something the regulation in Spain ask for.
Any suggestion I'm all ears

I'm wondering the same thing:

ey Tremelune, yeahh I saw your post and I wonder if you managed. it's incredible, looks like is a huge milestone for everyone, I wonder if this is not a signal to star creating a startup just focus on this

For the moment, if I find something I will past here. I saw something about the Azure, but difficult to find and still we need controller.

Finger crossed.

Hi,
I did a MINI Cooper S (R53) conversion back in 2012/2013 and commuted to work in it for a few years. I had a lot of fun doing the project. It had a 15kwh battery pack, an AC51 motor, BMS and 2500 Watt charger.

You can see a lot of photos here.

I've owned an ICE MINI since 2002 and hence have a lot of knowledge of the donor car.
If you are like me, you want to do it your way, but if you have any questions about how I did some things, feel free to ask.

Good Luck!

Chris

Hi Chris,

Nice pictures and videos!!! Looks great, do you still have it? I hope I will have this Eureka moment soon, probably this month we will finish the project if we manage to sole the AC compressor problem.

Looking for some solution, or use the Nissan Leaf one without control board or buy other that we can fit.

Did you use AC?

 

[csuich]

I never did the AC. I had considered buying a high voltage compressor and have AC lines fabricated. I could not justify the cost at the time. Now I imagine used components are more readily available so the cost ought to be lower. I've also seen more DIY AC lines sites, so that should be easier. I did install an electric heater core in place of the water heater exchanger.

The MINI made a great donor car with a brake pressure sensor for variable regenerative braking. The electronic accelerator pedal connected directly to the controller. The speedo just worked.


BTW you should find that the power steering pump just works. I believe that the computer must be in a limp home mode and the pump just comes on with the key in run mode.

I dismantled the car last year. We had moved to the western NC mountains a few years ago and I wasn't driving it much after we bought the MINI Countryman SE All4. I am getting my all battery driving with the new car and it gets us to town and back.

I am just starting a build. I am way behind you.
I have just purchased a Tesla AC compressor. My decision was driven by this thread. Tiger82 seems to have it figured out. I bought the exact model he specified.

I am struggling with Hvac controls.

Also what water pump are you using?

Yeaah, I will continue looking and reading about the AC, seems the reverse engineering is not that simple, at least when my system is almost done and can't change inverter etc..

and yes, the power steering pump works fine. I hope this month will be finish and I will paste here the videos and pics.

Hi Atlaw, good luck with the conversion, it's great fun.
I'm not sure about the AC yet. I wouldn't be sure tesla one is doable. I was reading a lot and still thinking. I probably will talk with Damian this week and will see what he recommends. At the moment I have option to go through an Azure Dynamic hacked.

About the water pump, I don't think I used special one, tomorrow I will let you know the brand but it's cheap 12v bought on ebay, nothing special.

The Vacuum one yes is hella 28.

Again, good luck with the conversion. Let us know witch donor car and convert car are you using.

yeahh, the water pump was the original from Nissan Leaf, forgot.

Does this operate on 12v or does it require CAN messages?

 

[Nacho]

Well, supposedly it should works without can as it doesn't seem to have module inside (small size), but I still didn't test it, I will next week and will paste here the result. Finger crossed

Hi all, adding more polemic info , I saw this in Aliexpress. What do you think? Is there something I missing despite "it's chines item"

Thanks guys

Speak to skooler about reusing Leaf AC
