Talking Got the EV grin!

I have been slowly working on my 66 MG Midget for the past 2 years and tonight I got it running and went around the block a few times!

I have to say I was surprised with the performance - it really moves!

Some general info:

- Zilla controller
- Impulse 9" DC motor. Original tranny with no clutch.
- 38 100AH Sky Energy batteries
- Chinoz charger

I still need to finish some body work and paint the car but I can see the light at the end of the tunnel...

I will post some pics as soon as I can find my camera.


Pete

Pete,

Congrats!! All the work, time, money and even the frustration pays off as soon as you press down with your right foot (my experience anyway).

Sounds like a great combination; light car, big controller and motor plus LiFePO4.

What is it like to shift? Mine is clutchless and was a really pleasant surprise.

Love to see pictures of the before and after paint.

Rob

Here are a few pics of the Midget today.

I have 12 of the 38 batteries under the hood and the remaining 26 under the trunk. The car sits about an inch lower in the front then back with this weight distribution.

As you can see I still have a lot of wiring clean up - this car was originally wired for positive earth so every bit of wiring has had to be torn out and redone.

Tonight I am charging the batteries completely for the first time.


Pete

After driving around the black a few more (20 at least ) times I can say that shifting without a clutch is not a problem - in fact I'm thinking I will rarely have to shift at all. It starts in 3rd gear with no problem. 2nd is just fun and will bark the tires if I get on it. And 1st is probably going to break something if I use it. So far my block isn't big enough to use 4th but my daily commute is about 12 miles of 60MPH road so I'm sure I will use it there.


Last night I fully charged the batteries for the first time. The charger ended with a voltage of 136v (3.57v per cell) this morning the pack is reading 128v. It seems a little low but well within the safe reign of these batteries.

I do not have a BMS yet but I do plan on using the Volt Blochers for the balancing. Then just using the low voltage warning on the Zilla for low battery. I will probably set that for around 115v and just stay away from the empty side of my pack.

That is a lovely project to work on, I'v always had a soft spot for the MG Midget as it was the car my first girlfriend drove when she used to pick me up before I got my licence.

Very nice, I like the MG's and most other little british cars as well. Are the positive earth electronics also a 6 volt setup? That's gotta be tons of fun riding an MG with electric!

Pete,

I hope you haven't pulled out a bushel basket full of wires yet. All you need to do is reverse the leads on your auxilliary battery. A Nash Metropolitan forum that I used to subscribe to describes the process, and the only other other step they include is to flash your voltage regulator. Since you're probably not going to be charging from an onboard generator or altenator, you don't need to have a regulator. Your gauges and lights don't care about polarity. The only thing I'd be concerned about is that Lucas probably made the harness, but if you haven't had any shorts yet, it's probably okay.

Nice looking job, by the way.

Mike

P.S.:If you've got a radio, you'll want to trade it out for a negative ground model.
