Hi,
> you're using T-875 8V floodies, and since they have more voltage sag than
> 6Vers I was curious if these high current draws are only when fully charged,
Yes, I've got 20 T-875s. The current draws of up to ~395 amps happen
most anytime I take off from 1st gear (and I'm usually close to flooring
it). Especially on inclines, I *have* to pull that much power in 1st
gear to accelerate up them. I also pull a lot of current in 2nd gear as
I'm getting up to speed. Third gear, no, I never pull more than ~280
amps because I *can't* seem to pull any more current. This is why my
acceleration at speeds greater than 55mph is incredibly lousy (at times
almost nonexistent).

Well, 1.75v per cell would be 140 volts in my case. So no, I'm not
keeping it above this because during acceleration the pack voltage sags
so much, even when the pack is full (~172 volts) it can sag as low as
155 volts under hard acceleration (such as from a stop in 1st). When the
pack is low, I've seen it briefly sag as low as 115 volts under heavy
draws. This worries me, but I haven't been able to find anyway to better
this, and I still haven't been able to figure out if I may have a weak
battery or two in the pack. BTW, the pack has never dropped/been below
140 volts when not pulling power from it (i.e. foot off the accelerator
or Jeep parked).
As a side note, I am switching the 80W90 gear oil in my differentials to
Redline 75W90 synthetic gear oil. Low-resistance tires are still on my
list, and a Zilla if I could afford one. Other than that I'm at a loss
for how I can make the Jeep work well at highway speeds.

Hi Everyone,
David Dymaxion responded to my question "how fast do you think the 200sx
will go from 0-60". He guessed 11-14 seconds. I was hoping for a

with it though. In anticipation of the 200sx finally running (hopefully
within the next 2 weeks if my batteries ever show up and I can steal
enough time over the Thanksgiving break), I thought I'd have a little

on how fast you think I'll go 0-60 (David, you'll have to refine your
estimate a bit). *The closest guess gets a free CafeElectric T-shirt!*

O.K. I understand real EVers don't much care for the comtuta / citi cars, but I
figured it was a good way to get our feet wet since I didn't have $10,000 to
put into a coversion. This particular car has been on the road for at least
21years and has over 124,000 miles on it. It was run at 72 volts by the
previous owner. I have no intention of putting highway miles on it. I'd just
like enough speed to not be a pain on the road.
Since it sounds like I need to up grade, I was reading the Modular Charger
post, I was wondering about adding a couple batteries to bring it up to 72v,
then keeping the K2 charger to charge 48 volts, and then getting another
charger to charge the remaining 24 volts. Would that work?
The controller is the other issue. I already drove the car about 6 miles with
the 60 volt pack and the curtis 1205. The car did fine on the small hills and
hit 45 mph on a good down hill. I'm told I'll burn up the contoller at 60
volts. If I up grade the car I'll be looking for a curtis 1209 48-72v or
equivilant. Does anyone have a used one for sale after an up grade of your own
perhaps?
Thanks for all the help.

This is exactly the way I used mine.
For certain kinds of people, regions, and/or vehicle missions, a C-car can
be adequate. And it is undeniably easy to work on; not only is it one of
the simplest vehicles made in the last half of the 20th century, I don't
think there's anything in that car that you can't lift by yourself (you
might need a little boost from a floor jack for the rear axle and/or motor).
All that said, I should point out that a decent conversion needn't cost
$10k, either. If you're willing to buy somebody's used conversion, you can
often get a lot for your money. The "rolling science projects," cars with
dull paint and dents, and those based on older gliders (15+ years) all are
less desirable to some people and can be had fairly cheaply. Many of these
cars use unexciting but reliable conversion parts from the 1980s; they may
not win any drag races, but they're often thoroughly reliable daily drivers
for folks who don't feel a need to compete in the stoplight derby.
You can still find such used conversions in the $2k-5k range, sometimes even
less. Of course they almost always need new batteries!

A jeep is a very heavy and non-aerodynamic vehicle. The system you've
got there is more suitable for a small pickup or even something like a
Civic - so don't be too surprised by the poor performance.
Not being able to pull more current from the batteries in the higher
gears is because your motor controller is in current limit all the
time, again due to the heavy and brick-like nature of the vehicle.

As I said when you first mentioned this: "1.86V per cell off-load
(you said you were stopped and measuring with a meter?) means you've
probably reversed a few cells."
I guess you've got your dash mounted volt meter hooked up now, and if
you're letting the voltage sag as low as 115V, well, that's what's
done the damage.
Measure each battery voltage just after you've been for a drive,
you'll find the dead ones.

Replace the flooded batteries with Exide Orbitals. It'll then
probably go about 5 miles at highway speeds.
Sorry, this is probably not what you wanted to hear, but this is a
good illustration of why big cars have poor gas milage, and that's why
most people choose a smaller car for conversion, or accept that
they'll have very poor range or very poor performance or possibly
both!

They can be good useful low cost Ev's if used like

I use a Citi-car motor in my EV and works well
after replacing the brushes as their leads had
corroded.

Cool, it has more EV miles than almost any other
EV on this list!!!
BTW my electric costs are about $.01/mile as yours
should be too. Batts run about $.03/mile.

For speeds, 45 mph is about as fast as you can
safely go in it.
Depending on your motor-differential ratio will
determine what voltage battery pack you need to hit
40-45 mph.. There were several used.
The voltage sets top speed and the amps set power.
To tell if you are not having a drag slowing you
down, check the amps, if over 100 at steady top speed
on a flat road, 2 way average, your speed problem
would be dragging brakes, bearings, ect.
If at or under 100amps you need more voltage,
batts to hit 40mph.

It could but you would be better off using 2
36vdc golf cart chargers as is or one ferro type, the
ones with a big cap in it and not much else besides
the transformer, by switching the full wave rectifier
to a bridge rectifier(diodes) to double the regulated
charge voltage to 72vdc nom..
Used one can be found cheap like $25. Free if you
can fix broken ones. Some GC shops are buried in them!

The problem here is amps. It was designed for a
contactor controller, CC, which will regularly put out
600-800 amps thus giving you the power to start up
hills, ect. Where the E controller rarely put out
their rated amps and cut back even more, quickly after
heating up.
So for better hill climbing, acceleration going
back to a contactor controller would give you more
power at much less costs.
You may have the original CC parts needed already
and using them with your E controller or can be bought
cheaply.
While the stock CC only gives you 3 speeds,
driving a low power EV is mostly digital anyway,
either on full or off. The other speeds are just for
parking lots and getting up to speed.
I think the Citi-car used as designed for is a
great starter EV.

Yes! That is exactly what they are. A great way to start cheap.

If this is true, then you have probably set a record. More likely, the
previous owner was exaggerating -- a lot! And, it means essentially
nothing in the original drive train is original. There is zero chance
that the original parts would last even half this long.
> It was run at 72 volts by the previous owner.
This I also find unlikely. He couldn't have with your 48v controller and
60v charger. (I am beginning to wonder about the previous owner's
honesty.)
> I have no intention of putting highway miles on it. I'd just like
> enough speed to not be a pain on the road.
That's perfectly reasonable. The stock ComutaCar is underpowered; they
used the smallest motor they could "get away" with. Reliability is poor
on these cars anyway; stressing the existing parts beyond their ratings
will only make things worse. So for better speed and accelleration, the
most conservative method is to put a bigger motor in it.
Check the present motor's nameplate; it is probably a GE motor, rated
6hp 48v 125a, or thereabouts. A Prestolite MTC-4001 10hp 48v 200a motor
would be great. A forklift motor would also be good (and cheaper), but
would be harder to mount (as it is bigger and heavier).

It would work, but would also be tricky to use and less reliable. You're
likely to have the 48v and 24v parts of the pack at different states of
charge, which will cause battery death. I wouldn't suggest this approach
for a first-time EV.
Only add batteries if you're having a problem with range.

I don't know of a standard Curtis 1205-series controller that is rated
for 60v. So, you were living on borrowed time. The controller is *very*
likely to fail if you run it at over rated voltage!

My 72v ComutaVan came with a 3-step contactor controller (36v with
resistor, 36v direct, and 72v direct). I tried replacing it with a
Curtis 1209, and it made accelleration and top speed *worse*! So I went
back to the contactor controller.

if anyone actually responds and builds or even designs
something like this , please let me know as i am
planning a long distance Solar Assisted Human Powered
Electric Vehicle (SAHPEV) trip for this summer and I
have not designed the basic vehicle yet. I vassalate
between my electric bike that is already a proven
vehicle and a three wheel recumbent that i have not
built yet. any ideas and suggestions would be
appreciated.

Can one of you computer gurus out there explain to me why someone
would put up a site with the subtitle "The top ELECTRIC VEHICLE
resources on the net " and have absolutely nothing to do with EVs.
I'm confused. Is it some kind of scam or way of making money by hits.
Please enlighten me. There doesn't seem to be a way to contact them
and ask them what's this all about.

Looks like an almost automated attempt at domain squatting. There are
some individuals and companies who like to buy up domain names of well
known brands and companies who've overlooked a permutation of their
name, in the hope of making a quick buck. A lot of this kind of thing
went out when the dot com bubble burst, but currenteliminator.com was
only registered in December last year.. from HONG KONG!

This has happened to the charity I'm involved with as well and it's
not very amusing.

PS I forgot to say, you can apparently challenge this kind of thing
via the organisation "WIPO" but it's hassle you don't need.

Damon, you're probably surprised, because you weren't around in the late
90's when many of
us tried modular chargers with disastrous results.
Actually I am very aware of this and the only time I think of using modular
charging is as a finish charging system. So either the responses above are
cut and pasted together in a funny fasion or I misread the original post. I
think having some kind of high amperage series bulk charger whether it be a
PFC 30 or a bad boy with a voltage sensor or anything in between, which
turns itself off before the batteries reach the constant voltage phase and
leaving the finish charge up to a bank of modular chargers, is "the best of
both worlds." It seems to me that regulators serve the same function and
cost about the same, and I would rather spend my money on 10 - 20 soneil 3
amp chargers then 10 - 20 regulators (sorry Rich, but at least I got a PFC
plug in there for you), as I feel that they are better at giving each
battery exactly what it needs.
I bought a 3 amp Soneil, I don't even know how long ago now, but it has been
charging some battery in my garage almost every hour since. I never have to
think about it, however everytime I check up on it, it is doing exactly what
I expect it to. It seems very reliable to me, and using a slew of these as
finish chargers seems easily as reliable as using regulators to finish
things off correctly. Since all batteries are already charged up to ~80%
before switching to modular charging the potential for disaster is limited.

I've been following this thread since the beginning, and it's very
interesting.
I've heard good arguments about reliability of modular chargers (or lack
thereof), and the problems this can cause. Lee said that good power
supplies make excellent chargers -- of course these are big bux.
I've been looking closely at the Soneil brand. My question is: does
anyone have failure information about this specific brand?
For their 24V 8A charger, Soneil claims:
Mean Time between failures (MTBF): 50,000 power-on-hours (POH) or
greater. This translates into 10 years of everyday operation of 8 hours.
Can anyone dispute this?
You can get 10 of them (which can charge 20 twelve volt batteries) for
$1600.
Assuming that the reliability is what's claimed, isn't this a good
deal? Has anyone checked out the power factor of these?
Next question:
Using a PFC-20, and a full set of regs, can you achieve as good
per-battery charge as individual chargers? The charging amperage cannot
be beat for the price, plus the power factor is correct, and you don't
have to worry about how much current your separate regs are drawing.
Now that I think about it, I think that the PFC + regs would be a better
choice, but I'm still kinda on the fence.

The Kim Komando minute today on the radio said rules have changed,
that others can take an existing domain name just for asking for it.
She advised making sure your domain name service has your contact
info correct, and to ask them to lock down your domain name to
prevent its theft.

When Dennis Berube failed to renew his site it was picked up.
www.currenteliminator.net is his current URL. I just couldn't
understand their reasoning for picking it up and putting up false and
missleading information.
