Jerry,
If you haven't found the Citicar info you need let me know. I have some of the manuals and could look for the pages you want. Nu-Kar has an excellent manual which includes all of the C-Car models, costs about $40, might be worth getting if you will be doing a lot of work on these vehicles. 

Gail
P.S. When you become a C-Car expert please consider opening a branch office in Las Vegas. My last great maintenance guru had too much else to do and I think got sick of trying to keep the C-Cars functional.

           Hi All,
              I need a diagram of a Sebring-Citi-car,
especialy the reverse wring from a later Sebring EV I'm
working on. It's been modified with a Curtis controller and
presently using a battery tap for the 12vdc curcuits so much
work needs to be done.
              Also I couldn't find the Citicar list. Anyone
can give me a hand would be greatly appreciated.
              Please stop playing Dan's the troll, game as
it waste the list, listee's time, resources. Could he be

                              Thanks,

I checked out their site and seen this charger,
1Amp battery charger,
http://www.batteryspace.com/index.asp?PageAction=VIEWPROD&ProdID=3331
# Bulit in IC which can automatically determine NiMH
battery pack's voltage and set charging voltage  to a
correct value
# Built in IC to cut off power automatically when
battery is fully charge by minus delta V  (-16 mV) 

http://www.batteryspace.com/index.asp?PageAction=VIEWPROD&ProdID=1298
3300mAhr, 7.2Vdc pack

I'm wondering how suitable the charger listed above is
for that battery pack.  It says it automatically
checks pack voltage and then uses a -16mV delta V to
determine when the pack is charged.  Seems pretty
vague to me and I wonder how well this charger works
for packs like this?  Just wondering if I should waste
my money on this.
Thanks,
Rod

Jim,
You're one of the best resources on this list for
motor information!  If you feel overwhelmed, perhaps
we can send a secret code word in the subject line to
get your attention?  Something like Jim, WTF, I have a
motor question.
Thanks again for all of your contributions to the
list.
Between you, Lee Hart and Jeff Major I'm learning new
things every day.
Keep up the good work (until John, Bill Dube, or Mike

I've got a new zilla 1k ehv with the stock motor speed sensor.  I need 
to mount the speed sensor on an ADC 9" double shaft motor.  I'm sure 
that someone has already built a bracket to mount the stock sensor at

The question that was asked is because I listed my
EV-1 controllers on the trading post again.  I'm
selling all 5 of my spare controllers.  I'm trying to
raise 1/2 the moeny for a new battery pack.

1 EV-1C, 2 EV-1B, 1 Two Stage Contactor Controller, 1
Curtis 72-120 V 400 A with blown FETs.  All the rest
work fine.  I am providing pictures and video of them
running on my spare motor.

The control cards I have say 24-84, 48-84, or Flight
Systems universal replacement card.  I run them at 84
V OK.  I even ran at 96 V on the EV-1B before I
replaced it with a 120 V Curtis 550 A (not for sale). 
My performance was OK at 84 V with the EV-1B.  EV-1C
is even better.  Not for a truck, but OK for a small
car.  Past 84 V, its at your own risk.  I did it for a
while, but it is off label use.

If I had an 84 - 144 V card, I'd put it on the EV-1C
and sell it as 120 V, but I don't have that card. 
Maybe there the same, maybe not.  We never did figure
that out.  I do know I had a 5H9 84 V card in my Jet
007 rated only 84 V, and it ran at 120 V.  That was a
Flight Systems replacement for the original card that
was 120 V.  So, maybe they are the same.  I never did
get an answer on that from Flight Systems.  Either
way, the stickers still say 84 V.

Hope that helps.  At least with the contactor
controller, you know for sure what you are getting. 
With the others, all I can say is they are OK to 84 V.
 The price reflects an 84 V controller.

Steve

--- Begin Message --- The HV9910 chip is a great constant-current buck converter that runs LEDs off of high voltage, not only efficient but also doesn't make a ton of heat behind the dash. Unfortunately it requires an external transistor, sense resistor, inductor, diode, and a couple of caps so it's a little on the complicated side.

I would use a panel -mount LED (or just a bare LED, depending on where it's mounted)
The disadvantage is you're wasting about 2 watts in the dropping resistor, but an incandescent bulb would use close to that anyway. 

On the plus side, it won't burn out or break from vibration.
For a panel mount, I use Digi-key's 67-1167-ND ( red) or yellow or green. You would need a dropping resistor of about 6000 ohms and 3 or more watts to give you about 20ma through the LED.

Subject: Indicator lamps for contactor operation
Date: Wed, 25 Jul 2007 03:42:40 -0700 (PDT)
I'm interested in wiring indicator lamps to the contactor output (2 contactor system) to show state i.e. open or closed. That means finding a small light or lamp that works at pack voltage (120 VDC nominal). Mouser shows a lamp (606-CM8-3995) that I think will do the job but I'm open to suggestions or experience. Has anyone found an interesting way to accomplish this? Will the lamp I mentioned work? 

TIA

I think that the requirement that NEV's not go faster than 25mph is
quite unsafe.  Because they are allowed on roads with speed limits of
35 and below.  We all know that when the speed limit is 35, everyone
is going more like 40.  So, if the NEV's could keep up 40 for a top
speed, and were still limited to roads with a 35mph speed limit or
below, it would actually be alot SAFER than currently -- because you
wouldn't have everyone passing them.

Now, whether the NEV itself can safely go that fast is another
question.  Probably the only question that the NHTSA thought about....

I've driven a think neighbor in traffic flowing about 30 to 35.... not
what I would call safe.  Nor does it endear NEV's to the rest of the
driving public.

I'm using the 185/70/14 on my 1977 240D Mercedes if that is any help.  They
seem to be wearing normally.  They did lower my gear ratio and my
hillclimbing improved.  The curb weight on the 240D is around 3000 pounds.

You have very valuable experience and information that

IMHO
It is political.  we may want electric vehicles but
there are powerful folks who want to make them as
inconvient and unuasable as possible.  It really has
nothing to do with saftey.  Untill Toyota, Ford, GM
etc make electrics (which they will only do when
forced to) we will all have an up hill battle.

About 120 HP..
At  100% eff and that's Electrical HP.. not shaft HP or shaft torque.
You still just don't get it...

300 amps is not going to get much moving very fast.

You need more like 1000 amps on the motors....or a LOT of gear reduction.

We designed a 1200 amp Raptor because Curtii had whimpy off the line
acceleration.

Try a more attainable design like 120 VDC and 600 amps on the motor loop.
You get to use affordable 200 volt Mosfets also.

Torque in a DC motor is all about amps.. getting a heavy Ev moving is all
about amps or lots of gears.

Hp is torque times RPM / 5252.  Figure you need .3 Gs to move off a light
with reasonable speed.

Kind of looks like a scam.

How many people with an EV on the EValbum got this
message, just curious,

Hello, My name is Robert Green. I just saw your EV on
austinev albums and thought I'd invite you to a new EV
conversion community I'm starting up. The point of the
community is to organize conversion information, help
facilitate communication between DIYers like yourself
and others and bring in parts vendors and fabricators
all to a single location to help everyone's projects
out. The end goal is to have guides and kits available
for most makes and models of standard cars and
community support for those attempting their EV
conversions.

You have very valuable experience and information that
I think could seriously benefit others and I think you
will find more information valuable to you in the very
near future. What I'd really like is for you to
introduce yourself or post a little info about your
past or existing projects to help me jumpstart this
database. Several admins will be checking the site,
sorting and grouping the posts and data to make sure
the site is growing in ways constructive and helpful
to you. I want this to start by being a place for
experts but gradually work in good information for
people new to the hobby so we can make it more
accessible for more households to start driving
electric.

My name is 'rbgrn' on the forums and I will be
available for contact there or at this email address.
Please have a look at the site and hopefully I will
see you online!

A neon bulb across the contactor will be lit when the contactor is not
pulled in and not lit if either the rest of the circuit is dead or the
contactor is shut.

I think there is a way with a diode to make it the opposite. Neon bulbs
can handle the high voltage and don't pass enough current to effect
anything.

I use to install them across fuses in machinery so they would light up
when a fuse blew.

Thank you for the response. Let me give you more info.

On evconvert.com's ev calculator you'll get 40 miles of range at 40
mph in my set up.

That's with a tire rolling resistance of 0.015. Which as far as I
know, is considered average. Now if I give it a low rolling resistance
of 0.10 I get 60 miles. That's a 50% increase!  Maybe since the
calculator is assuming constant speed, it makes more of a difference.
So let's say the improvement is only 25%.


For gasoline cars the improvement is supposed to be UP to 4%. There's
quite a large difference b/w 4% and 25%!

It really depends on what your comparing it to. I'm
sure if you had a really heavy wheel with a sticky
soft tire and compared it to a light weight wheel with
LRR tire 20% wouldn't be all that out of the question.

Let me put it in terms of my experience. My Saturn had
a set of mixed no name weather rotted tires on it. I
think I put 15 miles on them before getting them off
the car for safety reasons. At that time 40mph took
about 70 amps to maintain (I hadn't gotten an
alignment at that point in time), right after the
Goodyear Integrity tires were put on (they are at
least lower rolling resistance) it dropped this to 60
amps. This is with a 144 volt pack, but 60 vs 70 amps
is a 16% reduction in consumption alone, and when you
figure the peukert capacity that would very well
equate to 20%.

Now if you have a decently efficient tire to begin
with the benefit might not be so great.

Hope that helps,

Later,
Rick

--- Begin Message --- Generally, when running batteries in parallel you end up with the "Lowest Common Denominator" effect, i.e the group is only as good as the weakest battery. So at the very least you want to use good quality cells with very closely matching characteristics (e.g from the same manufacturing batch).
Lead acid and lithium work OK with being in parallel because they both have unidirectional charge/discharge curves, i.e their voltage keeps going up as the more charge you put into them.
All Nickel type batteries exhibit a peak in voltage when being charged and require peak detection for proper charging. Running multiple cells in parallel means each cell would have a different peak, and the stronger cells mask the weaker cells' peak while all the charging current goes into the weakest cell - which soon overheats & dies.
For NiCads it's not such a showstopper because single cells can be purchased in very high capacities, such as the Saft cells, so you don't need to parallel them. But large capacity NiMHs have been crippled by their patent owner (Chevron Texaco), and since they don't parallel well NiMH is pretty much not an option for EVs.
It's usually best to build a pack from a single series string of cells if possible, or multiple series strings in parallel (i.e B- and B+ of the series strings may be joined but individual cells are not paralleled.)
With my MX5 I'm going down the questionable route of paralleling about 80x small 18650 lithium cells into packs, due to it being the most economical $/watt at present.. Time will tell if it's bad idea or not!

As I understand it, lead acid batteries work okay being in parallel and NiMH don't work well in parallel. What about NiCad and the Lithium type? How many are too many to parallel in each case? What is the limiting factor in paralleling them?

I haven't seen it before you posted, but I have a very good spam filter, and 
it may have caught it.
