Trev,
Yea, cars got 12 volt systems. You'd probably want to
keep the winch system separate. I'd recommend you
avoid the 110 AC outlet. 24 or 36 volt DC is pretty
safe even when wet. You can feel a tingle wet at 48
volt DC, but it doesn't hurt. 110 volt AC can kill
you. It will be difficult to find a 110 VAC
controller for the DC motors.
With regards to the controller, you might be able to
just use a contactor with 24 or 36 volt battery. Slam
it on and off. But that will give a big jolt of force
to the guy at the rope end. A controller will allow
you to vary the speed as well as current limit upon
starting which will soften the jolt. Controllers are
rated for the battery voltage and motor current. A
golf cart controller would probably work with a
non-golf cart motor. Some of the old floor sweepers
didn't have controllers. Just turned on the motors at
a set speed to turn brushes, pumps and wheels. If it
has a controller, then I guess it'd work.

Which model of these cells are you referring to? I may
not have seen the original message about them. They
still are expensive, but still better than I have
heard earlier and still would like to consider them
for my conversion, if possible.

Hi EVerybody;
FINALLY got my new custom springs, for the 89 Jetta rear! No more Low
Rider!Car sits level, like there wern't 13 badd-eries in the trunk. Oh Joy!
No more bottoming out. I got the springs from Coil Spring Specialties in St.
Marys , KS. Took about a month, so ya gotta plan ahead. I mention this as I
like to share good stuff, with the fans, here.All ya do is tell them how
much MORE you are adding to the axle weight and they do the figgurin'. Isn't
cheap, as I spent about 200 bux. the fronts seem OK as the front end isn't
much, if any hevier than it was as a gasser? Of course you replace alota
OTHER stuff, too; Leaky rear slave cylinder, rear seals, new shocks, brake
shoes , and have the drums turned, while yur in there<g>!Brakes are a
hellova lot better, too!So back up to the 120 volts I knew and loved so
well.and Rich set the charger for. Wasn't gunnsa stick ANY metal object
through the adjusting hole after last time on the PFC -20! Hey! Rich, didya
inclose the plastic screwdriver ya mentioned I SHOULD have? I may have
overlooked and lost it in the wrappings.Plugged in and forgot about it last
night. Car charged and tapered off to 0. Nice!
Seeya Sat?

Damn, you sound like John! It'd been done if he'd had

so I just threw the piece of crap in the scrap bin 8^o
Actually Wayland was just here yesterday, so I sent
him home with Willmons 9's LMAO!
BTW where you do you live Tim? cause I'm thinking you

Having been rained out at PODC we were excited to head up to Thompson
on Weds night with our 3 untested vehicles.
We let work get in the way again and didn't make it out of the shop
till late in the afternoon. Brian had testing with his dirt track car
so we lost him as our OJ driver and his trailer that was to take the
Metro to the track. So with Denis and AGNS and his brother Eric and OJ
we headed to Thompson sans the Metro. We arrived late and sent Denis
immediately to staging while we prepared OJ for her first run with her
2 new Zillas and new DEKA batteries. Turns out I outsmarted myself
prepping the the V28's on AGNS. My plan was to cycle them in on Tuesday
night nd Wednesday morning, keep them artificially warm until we got to
the track, and have max power on the first run. This is exactly what I
did. Bad Idea. I did not realize that the temp cutback was still
operational in the batteries. Denis made his first run and limped down
the track with no power at 80 mph on a bike that was pulliing my
eyelids back just the night before. Too much of a good thing. Lesson
learned we parked AGNS in the trailer to cool off and concentrated on
OJ.
Because we were short on time we knew we would get only 2 runs down the
track. We pulled OJ off the charger with about 85% charge, turned down
the Zillas, and headed to staging for a shakedown run. No burnout, just
a light spin of the tires to clean them off. Light turned green and OJ
took off leaving a trail of white tire smoke for 200 ft. The hot rod
Camaro in the other lane roared out to a big lead as Eric, (who had
never even driven OJ), struggled to get her in line. She finally hooked
up at 330 ft. and blew past the Camaro at the 660 mark like it was
standing still. Eric finished the run with a 11.54 @ 119.9 MPH. Not
back considering Eric wasted 1-2 seconds lighting up the tires. We took
OJ back, lowered the tire pressure 30 % charged her up full this time,
turned up the Zillas to 3/4 power, and headed back to staging with
plans to do a nice warming burnout. It was a nice burnout until we blew
tha left rear tire off the bead with a loud bang. I thought we had
blown the tire but inspection in the pits showed it had merely lost
it's bead. We had just had the same tire at the shop earlier in the day
to repair a small hole it had gotten as a result of a large staple in
our parking lot. I suspect it was never fully seated. We reseated the
tire, bumped the tire pressure back up to be safe, and headed back to
the line. Because of the incident I told Eric to forego the burnout.
However, while watching from the bridge above the line I saw the guys
roll him through the water box. Just as I told him to Eric only made a
quick spurt of the throttle not realizing that his tires were soaking
wet. The crowd was in great suspense as the light turned green. When it
did a cloud of white smoke went up around OJ like John Force had done
it. OJ started sideways toward the tree but Eric got out of the
throttle a straightened her out. He got back in it and spun the tires
another 100 ft until it hooked up. At this point she took off like she
had a JATO rocket on her until the 1/8th mile mark when we heard a pop
and saw sparks come out for the remainder of the run. I assumed
immediately that it was the left rear motor giving way but when Eric
returned I found out I was mistaken. When OJ finally hooked up the
immense torque had actually sheared the hub bolts. We found the left
wheel and tire flopping around on the axle. This was what had made the
sparks. All 8 motors were cool to the touch like they hadn't even been
run. The inherent nature of the PM motor kept it from over revving when
the hub came loose and it was undamaged. The tandem wheel setup
supported the loose wheel and let Eric finish the run even though he
coasted most of the second 1/8th. All that happened in 11.41 seconds.
When he finally hooked up Eric managed to get to 106 MPH in the 1/8th
before the wheel hub came loose and coasted through the 1/4 at 111 MPH.
We loaded up and headed home considering the night a beautiful
failure. OJ showed unbelievable torque, the crowd loved it, and
dispite the problems at the end we were gigling like little girls.
This little car, when dialed in, is going to be in the single digits.
The topper to the evening was when the announcer (who had never seen OJ
before) came on after our second run and said, " The electric dragster
smokes the tires at the line and still runs an 11.41. They told me if
i stayed at this job long enough I would see everything. Now I believe
I have".
Look out Friday night!!!

Electro Automotive does a lot of adapter plates. They may already have
the type you need, or, if you need a custom one, they will pay to ship
the transmission to them and back, just to add the pattern to their
library, as long as you end up buying the adapter from them.
They're also active on this list.

Hmmm. From that website's prices and specs, I could get a 144 volt
200AH pack of Lithium batteries for "only" $18,000, and it would only
weigh 750 lbs. Compared to a bank of T-145's, that weighs about
1700lbs, and costs about $2k. So, my wallet would be much heavier
with the lead acid batteries :) Plus, the battery management
system, etc... Still, it's better than last time I priced out the
lithiums -- I came up with around $60k

I am really confused about the whole "Truncated message" thing. I see
my first post of this message as truncated so I sent a new one but
now I see that people have responded to my first email!!??? How can
some people read it and not others?
p.s please change the title to "truncated email" or something when
you respond so as not to mix up my original thread.

Electro Automotive also gets my vote.
They did my WarP-11 adapter and it is an absolute work of art. The
pieces press together with an accuracy of 0.001". It even presses onto
the motor bearing housing to ensure exact alignment.
They are a bit slow but well worth the wait. You really can't rush that
kind of quality anyway.

There is no doubt that you pay a premium for lithium batteries over lead,
but as you pointed out, it is getting cheaper. The thing that makes lithium
so appealing is that it allows you to convert an exisisting car and end up
with a conversion that has functionality on par with the original ICE
version. This will never be the case with lead acid. With lead you always
have to make a major sacrifice in functionality whether it be range,
performance, or cargo space. With lithium this is not the case. Also, the
up front costs of lithium will probably get amortized over a longer period.
It is likely that your $18,000 lithium pack will outlast multiple
replacements of your $2000 lead acid pack.
I expect all my EV's will be lithium some day, just not yet...

Azure Dynamics to Supply 1,000 Electric Vehicle Systems to Electro
Autos of Mexico for Conversions
9 April 2007
Tsuru_ext_02
The Nissan Tsuru.
Azure Dynamics Corporation has signed a supply agreement with Electro
Autos Eficaces of Mexico (EAE). The initial order is for 1,000 drive
systems for integration into the Nissan Tsuru—a vehicle based on an
earlier generation model of the Nissan Sentra—which is commonly used
in the municipal fleet of Mexico City.
The Tsurus are being converted from gasoline-powered vehicles to
electric vehicles as part of Mexico City Mayor Marcelo Ebrard’s
initiative to improve air quality and general health and quality of
life in the city.
Mayor Ebrard will drive the first converted vehicle to the
International Electric Vehicle Forum on 8 May 2007 in Mexico City.
The balance of the 1,000 vehicles will be converted over the
following 18 months. Azure’s scope of supply for the 1,000 drive
systems includes the motor, controller, gearbox and DC-DC converters
and is valued at more than C$7.0 million (US$6.1 million).
The agreement also includes the potential for Azure to supply a broad
range of electric and hybrid electric drive systems and components
for various other vehicle applications in Mexico.
With a population of approximately 25 million people, Mexico City is
the third-largest city in the world and currently operates more than
25,000 Nissan Tsurus to conduct government business throughout the city.

If I did the math correctly, $6100 for the motor,
controller, gearbox and DC/DC. I assume AC. I never
heard of Azure messing with any DC motor. They did
not mention batteries. Wonder what they'll use.

Thank you for the responses I received several days back on the Advanced
DC motor. I was looking for more torque in a motorcycle project as the
permanent magnet 24 Vdc motor I have and high gear ratio on paper is a
disaster. The new motor has already arrived and I E-mailed Advanced DC
to see if they could provide a little more data. It does have a drive
end bearing which is good, very good. Class H insulation. 24 Volts DC,
series wound (S1 S2 A1 A2 terminals). 6.7 inch X about 9 inches long.
Looks like 4 brushes, no covers over brushes. The drive end is sealed.
The brush openings are the only open area for ventilation / cooling. I
plan to use some type of mesh to keep debris out while allowing cooling.
If the motor runs hot, I have seen where others have disassembled and
machined holes in the front of the drive end housing for air cooling.
The exposed shaft is 1 3/8 inches long and is 13 spline .875 inch. I
plan to have a tapered bushing broached in its bore to give it the 13
spline form. This will compress when the matching tapered belt pulley
is bolted up and tightened down. I just need to do some thinking here
as the shaft could use to be a little longer, and the pulley and tapered
hub that I have are thick, heavy pieces. As long as the tapered hub is
being machined, I could have some excess weight removed, and thin it
down a bit to make mounting it easier and more secure on the smaller
shaft length. The rear pulley is aluminum, and mounts up easily to the
rear wheel (think Harley Davidson) so I am not wanting to change the
whole set up.
If Advanced DC does not give me a rotation direction, how do I verify?
Do I run the motor in both directions on 12 Vdc and see which direction
gives the most speed, and assume the brushes are advanced for that
direction? If the speeds are the same, do I assume the brushes are not
advanced?
My Curtis controller is rated for 24 to 36 volts. Do I need advanced
brushes to run a 24 volt series motor at 36 volts?
Thanks for the help. I am starting to find parts for the project in
spite of trying to buy a home (with no garage). I guess I could leave
it at my father's shop (he has a welder, etc.) He is only slightly
agitated by the old Mercedes diesel I left there (It did run for maybe 4
years and got me through some lean times).

Hey Alan
I'm not familure with that exact motor so I don't have
a lot of input. I can tell you that using 36 volt
won't get you to high a top speed as was also posted.
You'd be able to run it at a higher voltage if budget
or needs dictate. You would have to advance the brush
timing to prevent the brushes from arcing but it's a
fairly easy mod to do.
As far as the motor goes it in fact does look new and
should work very well for you, you'll just need to
feed it more voltage for anything beyond city driving.
One word of caution, make sure it has a DE bearing as
it appears this may be a type that doesn't have one as
some just slip into the drive unit.
Hope this helps

Electro Automotive does a lot of adapter plates. They may already have the
type you need, or, if you need a custom one, they will pay to ship the
transmission to them and back, just to add the pattern to their library, as
long as you end up buying the adapter from them.
Have they changed their policy? I thought that you had to buy a complete
kit from them ( $5K and up) before they will pay to ship your transmission.
At least, that is what it says on their web site.
That's what dissuaded me ( a couple of years ago) from having them make an
adapter for me. I already had a motor and controller so I didn't need a
kit, and they didn't have the pattern for an Echo.

"If you are buying a kit from us, we will pay for the shipping in both
directions, up to $150 total. This is how we expand our library of
patterns. For details on how to ship your transmission to us ..."
Depends on the definition of "kit," I suppose. Looks like you're right:
$5575 and up.
I stand corrected.

Besides pricing, proper BMS is high on my list of priorities, and as much as
I hate to admit it, I'm waiting for other people to spend their money
experimenting so I don't lose mine. I know that there were several on this
list that lost money to Thundersky already. Not that that means that their
batteries are no good, but the batch these people bought turned out to be
stinkers.
If I had to choose a lithium battery today, I would go with either large
format Kokam LiPo, A123, or Valence. I only know that because others on
this list have been down that road. In a few years if I can afford to go
lithium I expect to hear reports on even more intriguing choices and would
not be surprised if some enterprising EVDL member is selling a turnkey
custom lithium solution.

Steve and Daniel, yes the prices I was quoted are considerably less and as
follows:
LFP160AHA $255 160ah at 3.2v 5600grams per cell
LFP200AHA $320 200ah at 3.2v 7600grams per cell\
LFP400AHA $640 400ah at 3.2v 13.6kg
40 cells of the LFP400 would weigh approx 1200lb and would provide 144 mile
range and cost about $25,600. Prices are not bad if you are looking at
powering a small bike.

I was just wondering if you could use aluminum wire
for your EV.
It has the benefit of being lighter, but not sure if
the added resistance would hurt the efficiency, and
then you probably need larger size cable...
And does the stuff come in small strands?
Thanks

Sounds like a bad idea to me. Not because of the aluminum (though
yes, you will need to go to a bit larger size for the same current),
but because you cannot get superfine strand aluminum wire (that I am
aware of). The thought of trying to wrestle 500MCM stiff wire around
doesn't appeal to me too much... I only use fine strand copper wire
for the 2/0 and 4/0 main cables for battery PV systems any more --
tired of fighting with stiff stuff. I suppose you could use a pipe
bender and make custom bend wires for everything, more like big
aluminum bussbars than what we usually think of as wire... That might
be the only way to do it effectively.
Just my thoughts.
