[67BGTEV]

Working on the conversion of my 67BGT. I've created a blog

I'm going with AC Motor (may be I got scammed) and LiFePO Batteries

I'm hoping to get to 70mph max. 80miles Range @55mph.

The Progress will be updated here with a post, but details in the Blog above.

I checked out your blog. Good going. Nice little cars. I would not have ditched the clutch. You might find yourself shifting more than you think you will. A clutch would be good.

Thank You! We are thinking of implementing a electronic-neutral (bringing the motor rpm to zero on a press of a button) button on the shifter..

If anyone on the forum has implemented, appreciate any pointers..

Finally, adapter is complete and connected Motor to the Gearbox. I'm very happy with the outcome. You can see more details at my Bog

What is the point of stopping the motor at the push of a button? What you need is rpm matching the motor with the input of the transmission if you have gone clutchless.

In any event a 67 MGB should be a fun EV. Best wishes on your conversion.

Thank you, Do you have any idea how to do it.. suggestions?

I suppose it could be done by measuring the rpm of the prop shaft and then figuring out which gear you are trying to select and computing the necessary RPM and then commanding the inverter to spin the motor at that RPM. But I don't know anyone that has tried to do this. Usually you turn off coasting regen (or set it to an extremely low level) and use light pressure on the shifter until the synchros match and then the shifter will drop into gear. This works when shifting up. When shifting down you will have to drop into neutral and then touch the throttle to speed up the motor RPM manually. The lack of a clutch makes shifts somewhat slow and clumsy but you can do it with practice.

With an EV you find you don't shift all that often. The torque band is usually quite a lot wider and so you pick a gear and just stay in it. I use 3rd most of the time.

Thanks Doug!
Just a progress update - No Pictures, but puled the ICE, tranny and Drive shaft out, sold it.. This week, I'm goin to degrease and paint the engine bay..

 

[67BGTEV]

Underbody and Diff cleaned and painted..

 

[67BGTEV]

Quite a bit of Progress made:
Cleaned the Underbody, Diff; panted it..
Couple of pics here (more info on my Blog in my Sig):

Transmission Mount

More Pics coming up - Motor Installed!!!

Connected my friend's 101V Battery pack to my MG and used a regular pot to run the Car. It was in a drive way and couldn't go on a spin on the road, it works well!!
Next thing is to put the Pot Box, place the controller and stuff in its permanent position..
I'm excited!!

 

[67BGTEV]

After a long break, continued to work on the conversion. more details in my blog..

 

[67BGTEV]

Major progress and success!! Its drivable on the street, not completely drivable on the freeway.
Need to rewire the batteries, Motor and Controller with a thicker wire..

More on my blog.

Congratulations and best wishes on your project!

I kept the clutch on my '75 Spitfire conversion and don't think I'll regret it.

Let us all know how it behaves when you've got some more substantial wire in there!

 

[67BGTEV]

Thanks MM. Wiring is harder and tedious than I thought. Been wiring up with my friend for last few days and is not done yet!!!

 

[67BGTEV]

Wiring is complete and was ready to hit the freeway. We wanted to be safe and check the temp of all the components and pack voltage. We did that and drove 2 miles, stopped for one more quick measurement. Everything was normal, I switch the ignition on, boom, the controller blew up.
I've a different set up of driving at 100v and charging at 400V. Before I turned the ignition on, I forgot to switch to 100v and paid the price. Now, my friend Mine wired if such a way that contactor always gets 100V.
I bought a used 1238R, which is programmed for AC35. We'll check that wiring diagram is the same and plug it in.
Anything I needed to be worried about, since my motor is "AC45" (ac31) and controller is programmed fit AC35?

 

[67BGTEV]

Finally, all set. Drove the car 60 miles yesterday and fine tuned controller today. Drove another 50 miles. So far so good. Wired up J1772 female adapter, connected the avc2 and it works fine. Took out to a local nissan dealer. Everyone there went crazy looking at the car and appreciative of what I did. It was great to answer all their questions

Excellent news on your conversion. Pictures to show us? Do you have your full Leaf Pack in your ride yet?
