Word, I pretty agree with everyone. My sentiment is simply to give it a whirl the simple way, and if problems develop, reevaluate the design.

Too right, all this armchair engineering is fun, but ultimately somebody has to get off their arse and have a go to achieve anything. You have my respect for doing that.

Just wondering, if you use another frame based on the mini design aren't you going to have the exact same problems running out of space where the steering rack is?

 

I personally would continue with your mini subframe, by the way the towers lean back 4.5 degrees when fitted in the car

 

If you need more space where the lower suspension mounts are some people convert them to rose joints for more space for the CV's see below

Just out of interest I saw this article which uses a newly developed electric motor in a classic mini subframe

Thank you for this—this is rather important niche knowledge.

 

The problem with those aftermarket power plants is that they cost more than all the other parts of my conversion combined...

WOW !

 

That only weighs 1/2 a Mini lump.

 

Twin engine / four wheel drive / 200+ BHP...................away we go.

Charging is underway!
 
I was getting precious with my wiring and it was taking forever, so I switched to full on prototype mode, just throwing wires around to get things working...I'll make it nice once it's on the road and functioning properly...I've had to change things numerous times already, and I expect there's more to come.
 
Because I'm not using a DC-DC converter yet, I wired a battery tender in to keep the 12v battery charged as well...It's fun plugging an old Mini into the wall!
 
It's beginning to become difficult to make good progress without having the motor installed, and I've been eyeballing the subframe pretty hard. If I cut out part of the axle hole without cutting where the lower arm attaches, it might still work with some reinforcement. I have some time on my hands, so I might give it a whirl anyway. Worst case, I muck up a $500 subframe trying to save on a $2k subframe...Seems worth the effort.

Progress! Very nice to see.

 

Is this a "Thunderstruck"-charger? (Are you not using the original charger/DC-DC/BMS,....?)

 

Prototype-mode is exactly what applied to my project; after 9 months on the road and so many changes, the car still continues to be a protoype. :shy:

 

Kep it up!

Correct! It's their TSM2500 with their

charge controller and BMS.

 

I would have loved to use the Nissan charger, DC-DC, and BMS—it would have saved me thousands—but they're not quite hacked yet, it seems. https://www.diyelect...e DC-DC working, but took the video down (and it wasn't comprehensive). It would be amazing if someone could figure out the charger CAN bus protocol, but it's just not there yet. I might try and give it a whirl myself the next time around, 'cause you can pick up a 6.6kW Nissan charger for a few hundred bucks...You just can't control it outside a Leaf!

 

Most of the CAN hacking on the Leaf is being done to add features to the Leaf. That's...effectively the opposite of my goals of using Leaf components in the wild.

You should have a look into the norwegian e-driver's forum: elbilforum.no

There is a huge community as they have so many cars for so many years. Someone there may have access to the Leaf's CAN protocol.

(You might even stay with the original Nissan's components, and the optional 6.6KW charger.)

Markus
