Building a Land RoEVer

Brink, my energy level has been a roller coaster the past several months, is there any way you could convert me? On second thought forget that. I just had a terrible visions about what you might use for the battery compartment. :scare3:

Maybe a couple sparks in the rear compartment is just what you need. :yipee::yipee:
 
Brink- what kind of range does the mustang have? We have a Hybrid- the transmission in it is a CVT it is odd at first but now I love it.-

It was getting 75 miles.

I set it up with dual voltage, on board charger. He could plug in anywhere. It's called opportunistic charging.

Installed the clutch

Installing the motor to the transmission

It fits. The clutch works. All is good.
This is temporary. I need to work on the front motor mount. Then remove everything for painting and such.

And battery powered refrigeration units for NYC based food trucks. Now they don't have to idle their engines at each stop.

Here's the final assembly of the motor, flywheel, clutch and mounts. All ready to be installed. I will be using the original rubber mounts in the original positions.

Take a ride to Brewster one evening or Saturday and see it for real.

It's in. Now time to work on battery mounts.

This thread amazes me. I know that it is all about energy conservation and that sort of thing, but really, how much power does this electric vehicle have in comparison to the combustion engine. I know that the DC has a ton of torque, but how does it translate. (if you've answered this before, I apologize for asking)
Either way, an absolutely amazing build. Looking forward to when you do this to a Jeep.........not mine, but someone else's Jeep.

One thing that's cool about electrics is they make full torque at any rpm, good for smokin tires! :biggrin:

Actually, they develop full torque at locked shaft. Torque drops off as rpm's increase. These motors prefer to be lugged.

As for an ICE (internal combustion engine) comparison, generally, take motor hp x2 and that's roughly the same as ICE hp.

This chart shows the performance data.
Bottom line shows 135 ft/lbs torque and 44 hp @ 72v and 453 amps.
I'm boosting up to 168v and 1000 amps with a liquid cooled motor controller. This will outperform the original 4cyl, and be equal to the little V8 this one had.

OOPS! So that was it, full torque at low rpm.......or something like that. I guess that's why I am not building an ev, but they are cool.:hi2:

No pics, today.

After the meeting with the owner the other night, I was sensing there might be an issue with the transmission. I found a copy of the the owners manual on line and read most of the 136 pages. Come to find out, Rover didn't use synchronizers on first and second gear on these transmissions. So, up shifts into second, and down shifts to second and first can "grind the gears". Upon checking over the transmission, I don't see anything wrong with the transmission or transfer box other than some 56 year old quirks. Very very glad I decided to reuse the flywheel and clutch. Can't double clutch, when there is none.

I checked the wiring and light circuits, they're fine, just a few minor repairs to be made, such as LH signals don't work, and dimmer switch failed. Easier to do the checks now then try to figure it out later, especially when a ton of batteries are in the way. Also checked amperage draw with all lights and wipers going. I need to instal a dc-dc inverter that steps 168v down to 12v for the OEM circuits. This one pulls 15amps, so I'll order a 25a inverter.

The fuel tank, fuel pump, ignition coil, fuel lines and muffler have been removed.

I started laying out the batteries, I have to juggle the placement some, they won't fit where I originally planned, but I will get them in.

Also, started cutting and welding angle iron for the battery trays.

Still so much to do.
