I look forward to hearing about your C5. I was looking at buying one a while
back (needed serious work) but they dude was outrageous in his pricing...
$4K, if I recall... after he got down to pricing it out. Plus shipping.
(They sell for 70 to 900 BPS, from what I've seen.)
You've probably seen http://www.sinclairc5.com/, right?
I remember his computer. Unfortunately, I don't think the C5 was brought to
the US, except in rare cases. This car has a lot of Nerd appeal... and I
think it'd be perfect for Micro-car rallies.

I understand I don't need special wire, but I saw an installation once
that had what looked like a single cable. On closer inspection it was
power and sense in one insulation. It looked like a clean installation
and was wondering if anyone knows where the heck to get it?

Wouldn't use "This car" as a description! It's a faired recumbent
e-bike with under-seat steering, kind of an 80's version of
single-seat, unenclosed Twike.

I find the thread on e-volks interesting.
Here is a company that is providing an accessible EV conversion -
meaning easy to do, easy to buy. Sure, it isn't the EVDL's approved
solution of a million volts/dollars of batteries, an 8 inch ADC and a
Zilla and Rudman Regs and charger - but it 1) brings more people to EVs
than $9000 kits and 2) appears to work.
Website need some work? Sure. Name an EV dealer website that looks
like it was produced any time after 1996. If there is concern about the
"image" of EV's, there is an awful lot of policing to do. Has Chevron
locked up modern and attractive site design with patents, too? Maybe
its GM's fault.
As for representing the pros of a shunt motor, what exactly was
deceptive about it? Did they publish something factually incorrect? No
doubt they chose to promote a strength of what they had because it was
what they had. But didn't we have a really, really long thread about
the pros and cons of AC v DC, and wasn't it all about the advantages of
one versus the other? Was that deceptive and harmful to "the cause?"
I don't have any connection or financial interest here, either, but it
seems odd that a crowd that gets excited over the mention in passing of
electric vehicles in a movie review goes all medieval on someone
actually selling EVs.
What am I missing?

My needs were/are for an affordable LOW SPEED vehicle to travel to
and arround town. I decided on an electric vehicle but wanted it to
be street legal and not an NEV or LEV or golf cart.
The vehicle is not pristine .... http://tinyurl.com/oqp3g
but then my other car is a 2 door metro (45mpg) that I paid $300
for
The road (paved and flat) to town is 45mph .. 25mph in town. I
wanted 4 doors for the kids. I already have a E-bike
http://tinyurl.com/oqw96 running at 48 volts
but wanted a more weather proof vehicle and 4 passenger.
And I have a 48 volt solar set up.... http://tinyurl.com/ep4d9
The other day I hooked a trailer to it and hauled some sheets of
plywood home.
Someday I may go to 60 or 72 volts but for now 45mph and range of 25
miles is just right.
So if someone wanted to spend $180 for a surplus motor and figure
out the adapter, the rest of the parts are readily available
I have no affiliation with e-volks.

Hello to All,
I received the below from my friend Rod Wilde:
Press Release, June 12, 2006
"Gone Postal", a two ton drag racing postal van from the TV show
"Sucking Amps" on The Discovery Channel has been invited along with
the star of the show Roderick "Wildman" Wilde to the premiere showing
of "Who Killed the Electric Car" at the Los Angeles Film Festival on
June 24th. The movie includes such notables as Tom Hanks, Mel Gibson,
and Ed Begley Jr. Mr. Wilde was invited by Dean Devlin's production
company, Electric Entertainment. Dean Devlin is most noted for such
films as Stargate, Godzilla, and The Patriot.
Rod told the folks at 'Electric Entertainment' about White Zombie, and I
subsequently got a very nice invitation from them as well. They seemed
very interested in having White Zombie at the EVent...in their words, so
'they could showcase it'. What a great opportunity!
Rod and Tom True are making it happen and will have Gone Postal at the
Event. I am having to pass on it, due to work related travel to Alaska
and quite honestly, because I am still paying off the trip costs from
the recent 4300 mile ill-fated trek to Illinois and back with the car
:-( Had I only known about the anti EV Vortex canceling the High
Voltage Nationals in advance, I would have saved my vacation time and
money for this!
I sent a response back to Electric Entertainment (what a great company
name) telling them I couldn't make the EVent, and I thanked them for the
invite. It's an honor to have been asked :-)
I get back from Alaska to arrive in Seattle on Friday the 23rd, so I can
meet up with my car (thanks to Roy LeMeur who will be hauling it up from
Portland with my Jeep and trailer) at the BIG Seattle Greenwood Car Show
early the next Saturday morning, coincidentally on the same date (June
24th) as the LA Film Festival debut of 'Who Killed the Electric Car'.
Any EVers within striking distance of Seattle are invited to stop by the
SEVA electric vehicle display and say 'hello'.
Let's all wish Rod and Tom well, and hope they can rub shoulders with
some of LA's movers and shakers.
See Ya......John Wayland

Anything that gets folks driving more EVs is great, but if newbies get
pissed at the whole idea because of their "lowest common denominator"
kits, it's the opposite effect of a passing mention in the media.
Whatever anyone's opinion, higher resistance from bolt-on battery lugs
and an aircraft starter/generator that wastes 10-20% more than newer
series or shunt motors doesn't bode well for efficiency.

Hello John,
John Norton writes:

As did I, but I didn't find it hostile. Quickly re-scanning the thread, imho it
seems like a pretty balanced discussion overall. If nothing else, it looks
positively tame compared to some other discussions around here :-)
> What am I missing?
/shrugs Perhaps only that, like with anything else, different people have
different views, in this case on what constitutes an acceptable minimum
standard for an EV conversion, and hold them strongly? Unsurprisingly,
particularly when some have vested interests in arguably better and more
expensive solutions -- and I say that void of any negative connotation (rather,
that if they did not hold such views their interests would lie elsewhere).
I understand that there's also been a history of snake oil operations in the EV
past, and rising gas prices are sure to bring more out of the woodwork. Having
a skeptical and critical attitude toward relatively new and unknown players
sounds like a normal initial reaction; there's no reason why that should
prevent anyone from changing their mind when presented with evidence to the
contrary.
Cheers,
Claudio

But reading on this list at least informs would be converters what they're
getting into. I went all out (well almost) on all the premium parts for my
first conversion because I didn't want, as you mention, be "pissed" because
it didn't perform. Now from reading this list I knew just what to expect
from the vehicle I did put together. Mine performs exactly like I figured
from doing many comparisons. I think with the info I've read here I could
put together a conversion with my same requirements for half the price.
What I would be giving up would only be off the line acceleration. If I use
a $180 motor thats only 15% less efficient than mine, I can still get my
range by not hot footing it. I waste more than 15% of my range by burning
the tires from stop sign. The clincher is the price. The motor may be 15%
less efficient but it costs 90% less than the one I bought. Same goes for
the contoller, batteries and charger. The point is they cater to the crowd
that doesn't want to drag race their EV. They don't claim to make tire
burners. And who says that if someone built one and wasn't happy with
performance they couldn't start upgrading pieces at a time until they got
the performance they were looking for. Or they could buy the cheap kit, and
use the tips and tricks gleaned from this list to spruce it up a bit for
another very minimal charge, so to speak. I don't think the media cares one
way or another. I've never seen an article that says builder Bob down the
street converted a car to electric "and it sucks". Most are fair siting
limited range which is a very real problem for many. Anyway, why bash 'em
for doing the good work. I don't EVen know them but I bet they do it
because they enjoy it. If you buy their kit and don't like the results,
thats your fault, you should have built a better car. But if you buy it and
it suits yur needs, then you just got a really good deal. Thats true with
anything in the market.

If you knew what you were getting into, it's perfectly fine to go this
route. I think more people should be driving well-tuned beaters!

Now *that's* appropriate technology! Using a trailer for big loads
would eliminate some drivers' arguments for driving pickup trucks, and
if you drive an SUV because you frequently need to seat 6 or 7 people,
how about a minivan or common station wagon with a 3rd row seat?

A $145 adapter plate is not bad, but some converters might want to
replace that generator with a more efficient motor with different bolt
pattern. If your car fulfills your needs, you probably aren't worried
about this.

I wouldn't say that... if you coast one quarter of the time driving
around town (easy enough once you get into the habit), you're reducing
mileage on the transmission by that amount. And those things have
specific lifetimes.
It's more than that.
I was curious late one night (early the next morning, really) about this,
and I drove about 40 miles doing nothing but accelerating up to 70, and then
putting the car into neutral and coasting with the engine off until it got
back down to 50 again. It boosted my mileage quite a bit - 26 mpg instead
of 22. (The car had a mileage-so-far feature that I reset prior to trying
all this)
Of course, the only reason I could do that was because there were no other
cars on the road. Had I done it during normal hours, I'm sure I'd have been
honked off the road.
Also, there are people who get a kick out of driving their Prius so they
average more than 100mpg. It's much the same: you accelerate for a little,
then coast for a long time, then accelerate a little, etc etc. It's
described as "Pulse and Glide", the article is at:

Well, that was a waste of time...
I had a tip-off that there was one in a local yard for £40. I turn up
and sure enough, there's one there, at £40 condition. The tires were
flat, the front faring was slightly bent, the left brake was bust,
the key was missing (though it was a dual battery model) and it was
really filthy.
But, the guy had a tag on it of £325!!! The guy was obviously smoking
pot or something when he made up that figure (no disrespect to those
who partake of course - it's a free world!!!)
Anyway - he wouldn't shift even though I told him the C5's real
value. It's apparently been there a long time and I expect it will
stay there a while at that price. Still, at least I now know it's a
no-brainer!
Onwards now with the calculations for the Eminor, but first a quick
question for the Canadian/American guys....
I want to keep my standard tires on the minor, but I'm worried that
155/80 R14 are going to be a pain to get hold of... Anyone got any
comments?

I know several people on here have one so is there anything I should

Q2: I read several posts back about the typical Pot Box input values for the
Hairball2 and was wondering what the typical values are for the HEPI? I
have an idle value of 0x3A and a full throttle value of 0xE2. It seems
that I don't see current start to flow until the accelerator input is around
0x51. This represents a very slight depression of the pedal. I read where
you stated the Pot Box input at full throttle input should be around 0x9F.
Does this mean the difference between 0x9F and my HEPI max of 0xE2 is wasted
throw on the pedal? This represents about half the pedals' throw.
Thanks

Sorry for the long delay in replying to this. I just happen to be
working on this code today and so had a chance to verify values.
My previous statement that full throttle is at 9F is incorrect. It's
actually D4.
New correct pot data is this:
Pot input values for 5K input:
These are also valid for the first value when using the HEPA.
Low pot, 0x47
High pot lockout, 0xF6

Nikki,
I checked and at the moment there are 7 C5 for sale in The
Netherlands at the "Marktplaats.nl" site.
No doubt in the UK there should be a comparable number
being offered.
Prices for good, clean running ones start at Euro 350.
For availability of a specific tire size or type, I usually
check online with (for example) The Tire Rack:
http://www.tirerack.com/
Click on "Tires by size" and fill out the fields to see
>that they do not have this size< (bummer).
So I googled and found the UK company AutoSock specifying
a 155/80-R14 tire. http://www.autosock.co.uk/ASsizeX.html
Also TireSite (UK) has this tire size from Nankang and Toyo:
codes 1558014NANKANG and 1558015TOYO310
With this info you may be able to either find a supplier
in N-America or ship a new set of tires with your car.
Success,

What hostility? Who's angry? Have I missed something here?
As I said in my initial comments, I wish them well. As long as the buyers
understand the limitations of the EV they're buying, they provide a worthwhile
service.
I do think they're missing out on a larger potential customer base because of
their website. Most people would probably agree. Some other respondents
remarked that "you get what you pay for." That's pretty hard to deny, too.
I think the discussion has actually been pretty genial. I'll admit, there are
a
few people on this list - just a few- who DO make like attack dogs when it
comes to beating up ideas and EVs that don't meet their personal standards.
However, none of them has weighed in on this - yet. ;-)
I hope this clarifies things.

This seems to be the first answer I've found that will handle 240 Volts and
OVER 20 Amps.
The price is a bit high, but not unreasonable at ($234+$39)

Try alpha wire PN 1243/2C (2 pair individualy sheilded per pair + over
sheild) or 2466C (both pair in the same sheild (watch out for crosstalk))
more info http://www.alphawire.com/pages/234.cfm
Digikey stocks 2466C.
BTW,
22 gage wire is rated for 7A in a chassis or 0.92A as a power cord. 16 Ohms

I understand I don't need special wire, but I saw an installation once
that had what looked like a single cable. On closer inspection it was
power and sense in one insulation. It looked like a clean installation
and was wondering if anyone knows where the heck to get it?

Can anyone explain why a message I posted on 5th June takes 9 days to
appear on the list - other messages I post don't seem to get to the list at
all and yet others appear quickly.
Is there an "extra" time delay for European posters ??

Subject: watthour meter AC side
Does anyone recomend an AC side WattHour Meter?
I am specifically looking for something that I can mount on the car so I
can accurately track input power wherever I charge.
There must be something panel mount, but no catalogs nor websites turn
anything up.
Thanks for any leads.

The Warp and the AvDc are basicly the same motor. Buildt by differnt folks.
The Warp give you a little better cost benifit ratio.
John Wayland won't be using Field weakening again this year.. too much brush
carnage.Messing with field strengths is a carefull adjustment and test
thing.
Not blast it to bits and then sweep up the peices.
Maybe at 28 to 48 volts but not at 360 and 2000 amps.
The motors are wound for the 48 volt for lower voltages, The high voltage
motors seam to be the same build from 96 volts and up. We have seen the
exact same motor badged from 96 to 156.
So.. What changes??? We don't know. The have the same case, Comm and field
turns. Pretty much the same motor then.

They also have a cheaper unit for 120vac linked on that same page.
It's called a Watt'sUp.
That 240vac unit looks to do a lot good things.

I don't know about the 9 days delay, however, I can explain at least
part of the delay:
X-Greylist: Delayed for 22:15:50 by milter-greylist-1.6

This is from the header of your message and indicates that for some
reason the SJSU ListProc has decided to put your address on a grey list
such that anything you post will be deliberately delayed before
appearing on the list.
A while back my address somehow ended up on this list, so I know how you
feel. I'm afraid I don't know how one gets their address off the list;
I emailed David Roden about the situation and while I didn't hear back
from him, sometime later my posts started going through normally again.
I don't know if this was coincidence or David working diligently behind
the scenes. ;^>
Cheers,
Roger.

It looks like it may be a pain to get that size over here.
155/80R13 is available, but the skinniest R14s seem to be 175 and 185.
However, 175/70R14, 185/65R14 and 185/70R14 are all commonly available
here and work out to have very close to the same height as your
155/80R14s so your speedo, etc. would not be thrown off enough to worry
about.
Difficult to get does not mean impossible, it just means you may have to
source your tires from a specialist shop rather than being able to pick
them up just anywhere.
Cheers,
Roger.

Thankyou Roger and Eric who sent me a breakdown off list.
I hope that if anything is slow on the "sjsu" side it will be picked up by
Admins. I certainly will ask my ISP why my mail was delayed on the first hop
too.
Many Thanks
John

All,
Having caught up on e-mail (the hundreds of electric vehicle discussion
list e-mail that is) and home-front chores after being on the road for 12
days with the KillaCycle (.com), I'm way overdue for an update post!
When I finally returned with the KillaCycle from the AABC conference in
Baltimore, Maryland (I'll have to post more about the road trip later, as
John Bryan has been requesting the gory details!), my mom had been in the
hospital, so I spent some time hanging with her. After the hospital fun, I
was busy pulling dead burr (burdock?) bushes so the daughter-unit's horse
would have something to eat without getting burrs in his mane, eyes, and
tail. Prior to leaving town for Joliet, Illinois for the rained out
NEDRA.com gig, I had drug home a dead '81 RX-7 for parts to fix the
eelectric '79, in particular, a rear axle and mag wheel wheels (the
daughter-unit had spun out in a snow-storm and smacked a curb, and the
rear-end sounded like the engine room on the star-ship Enterprise!). So
with the REALLY HOT weather we've been having, I've been spending the
mornings pulling weeds as a yard-monkey until it would get really hot out,
then I would work in the shop as a grease-monkey until it would get really
hot in, then I would take refuge in the basement of the house to do paper
work and read e-mail as a chair-monkey! Last week was spent moving my son
out of the house and I also had relatives from Indiana visiting...
Anyway, I finally finished the axle and wheel swap the other day, which
turned into a major job because the brake backing plate goes on the axle,
prior to the bearing being pressed on, so the brakes had to be
disassembled. Did I mention that the '79 had manually adjusted brake shoes
and longer wheel bolts for a thicker mag, and the '81 had self-adjusting
brakes and shorter wheel bolts for thinner wheels? After dropping the beast
off the jack-stands I put a few cycles on the batteries and fetched a
laptop 'puter to lower the Zilla's battery voltage cutoff from the Winter
snooze mode to the Summer let's-have-some-eelectric-fun mode! The last
couple of days I've been making sure the drive train will stay together
through exhaustive testing, hence the dual tire marks all over town! Today
I'll swap the idler arms and the beast will be ready for a trip to
Bandimere's drag strip, hopefully with my daughter-unit as the new pilot.
Hey Wild Bill Dube', why don't we take the KillaCycle out for some more
fun? It's a shame that all of Steve and Derek's work on the battery
management system isn't being utilized! I just had a dream about the
Lith-ion battery pack in the bike...
50,000 plus pure eelectric miles on the buggies, and a countin',

In looking at Field weakening I came across this paper
http://power.ece.uiuc.edu/chapman/papers/IEMDC%202003%202.pdf
from the Power and Energy Systems at the Univ of Illinois.
The conclusion states - "The mass and cost of the drive motor for traction
applications can be reduced by re-rating the machine as opposed to field
weakening. The process takes advantage of the wide frequency capability of an
electronic drive to deliver full output torque over an extended range. A 350%
increase in power output over the nameplate rating was achieved on a stock
10HP, 60Hz, induction machine without violating any ratings. The machine was
able to replace and internal combustion engine, and provided high power to
weight ratio in an inexpensive air-cooled system"
A 350% increase by re-rating the motor?
If I read it correctly all they are talking about is rearranging the stator
winding taps on a 3 ph motor to provide a low voltage delta connection and
using a source to provide 200v at 300 Hz.
Anybody with a little more elec/motor knowledge care to comment on this?
