First - my apologies for the double post - operator error!
Secondly, thanks to all who responded with info, both off and onlist.
This could be the pot box , what kind of controller , pot box do you have .
??
you can take a ohm meter (dmm) and check it .
The controller is a 48V AllTrax. Don't know about the pot
(potentiometer?) box.
you mean the motor is trunning and the transmission is in gear but its not
moving ?
Yup!

EV enthusiasts from the list are probably going to

- _____ heater
- _____ suspension upgrades
etc. etc.
I know this is tougher for you, b/c you have homebrew
electronics (and high-quality stuff, at that, but it
would still be a bit more attractive that way. Just
my 0.02.

One MINOR issue to resolve:
Every once in awhile, I hit a bump, or accelerate
hard, and there is a brief chatter between the bottom
of my firewall battery rack, and the motor.
One way to resolve it is to re-do the battery rack.
It's not a big enough issue to merit re-doing it on
_this_ conversion.
Another way is to silicone some felt or rubber to
the top of the ADC 8" motor, thus absorbing the noise.
This approach depends on how hot the motor gets on
a 300A pull up a hill for example. If the rubber
burns, that's not much of a solution to the issue!
After a hard pull, my motor is HOT to the touch, but
quickly cools down.
Suggestions?

I don't believe there is a standard protocol but if you want to make an
RFC someone might listen to you =)
I have looked at data from my GM ECU and it is in this manner. Even
though the computer is in a 95 pontiac grand am, it still prefaces all
packets with the "95 grand am" hex codes. As a matter of fact, and
this may be of use, GM has standardized on powerPC controllers, they are
the same on all their vehicles and can be re-flashed to the tune of
about 2 meg of code, They are pretty powerfull units and are
interestingly built with integral heatsink that requires no fan. They
can read at least 4 PWM signals and have lots and lots of digital and
analog I/O with built in signal conditioning. Because of this they are
about $100 from a wrecking yard. Has anyone thought about using one of
these as a robust platform for charge control or regen control or ....
I had always assumed ECU units would be quite proprietary.

No; it's more a matter that you aren't likely to exceed its 200a
continuous rating. To do so you would have to driving up a very long
steep hill, or putting along in a parade at 3 mph in 4th gear.

I don't have the curves handy, but it's something like 200a continuous,
350a for 5 minutes, 1000a for 1 minute, etc. If you manage to exceed
these limits, the contacts would overheat and could weld.

In general, you're right. The motor-side contactor carries more current
on average. But in the worst-case situation (controller stuck on)
battery and motor current are the same. So it is common to size them
both the same.

Electrostatic and induction are two different techniques.
For induction, you'd start with a working charger. Saw the transformer
in half (figuratively), and put half in the car, and half on a cord or
in a plate in the floor. Bring the two halves together, and it works
like any other transformer.
The two halves don't actually need to touch, but the smaller the air
gap, the better. Also, high frequency transformer halves will be smaller
than 60hz transformer halves; but it works the same.
For an electrostatically (capacitively) coupled charger, you need two
pairs of insulated metal plates, or one pair of plates and a grounded
car. You want to arrange the plates for the largest surface area and
thinnest insulation layers practical. You apply a high-frequency
high-voltage AC between the two fixed plates. The power capacitively
couples to the pair of plates in the car. Again, there is no actual
electrical contact and no bare metal, so it's hard to get a shock.
However, the capacitance you can get with practical plates is quite
small. This requires quite a high AC voltage and frequency to couple any
significant amount of power. Since the higher the voltge, the thicker
the insulation on the plates needs to be to prevent shocks, this
approach is not nearly as practical for EV charging.

Standards do work, when they are made straightforward enough for
easy and inexpensive adoption. Witness TCP/IP over OSI, etc.
Thus my RS-485 comment. Simplest multidrop I could think of.
A standardized protocol can be layered ontop of it, or not.

Hmm, how are the battery boxes mounted? Possible to raise them up a bit by

Heavy loads can cause the motor/transmission to tilt up a bit, maybe lower

I looked at the car and it makes a Fiat 600 look big. If you like small
this is for you. There is room for batteries under the back seat, In the
engine compartment and maybe under the front seats. Front compartment is
very small. It has two bench seats(front and rear) Cute as a bug. I has
most of the parts and only 16k on the clock. It is in Mill Valley. There is
some rust but mostly surface. There are dents but fixable. I'd go for it
but I'd have to get rid of my half completed VW Rabbit conversion if I
wanted to do it. It has a back battery box and motor installed. to the
Arcaners this car has most of the parts. Good glass and turnsignal plastic.
The only thing I noticed missing was a connection between the aircleaner and
the carb. If someone bought my VW conversion then I could get the Subaru.
Reason. I could then get two cars in my garage. This is certainly a job
for Frank the Metal god. Just the kind of thing The Northwestern
contingent would apreciate. Lawrence Rhodes.....

If you where thinking of making one then yes for sure , Would I buy it and

It certainly can't be good for them. My friend David toasted two Chevy
Sprint (Swift, Metro, etc) transmissions with an ADC 6.7", so it
certainly wasn't from torque. Then again he did like to run 65 mph in
2nd gear. The second one resulted in a 65 mph skid too, so it seems
likely that the high rotational speed and failure were related.

I run ACRX only on the second gear. Sometimes up to 40 mph on first.
Do it since 1995, no problems so far...

Could someone point me to the study from which one draws such
conclusions as "x% of all car trips are less than 40 miles"?
The thing I would really like to be able to determine is this: What
percentage of cars in America could be replaced with electric cars
with a range of N miles without any change in driving habits (or with
families choosing who should drive which car but otherwise going to
the same places)? I suspect this isn't known because it would require
asking people the longest trip their car has ever been on or the
longest trips made simultaneously by all members of their families.
But I would settle for the question of what percentage of trips are
within a given range.
Thanks.

Would you still drive your car if the tailpipe came out of the steering wheel?

I'm considering an IOTA DLS-45 to replace my DCP DC/DC converter. I
need to know what the min and max DC input voltage is for these. I've
sent email to the techincal person at IOTA, but no reply. Since these
seem to be the Todd replacement, I thought that someone else may have
this data.

So guys, if I wanted to build a small scale electrostatic
induction system, how would I do it?
Electrostatic and induction are two different techniques.
For induction, you'd start with a working charger. Saw the transformer
in half (figuratively), and put half in the car, and half on a cord or
in a plate in the floor. Bring the two halves together, and it works
like any other transformer.
How large of an air gap will still work? 12 inches? 24 inches?
The two halves don't actually need to touch, but the smaller the air
gap, the better. Also, high frequency transformer halves will be smaller
than 60hz transformer halves; but it works the same.
Will higher voltage transformers be more efficient? Is AC or DC more
effective?

What are you guys using for a Peukert Exponent for Excid Orbital 34CD's?
I have the E-meter set at 1.09 but at the end of a week of charging and
discharging the LED charge indicator reports no charge while the battery
regs and voltage show full capacity. I remedy this by resetting each
week. Any ideas or suggestion?

This is worth seconding. And it is, by the way, what the batteries in
your laptop computer do. There is a microcontroller embedded in the
battery package that watches the battery while it drains, with various
other factors like the current temperature. Then it builds a set of
tables (pre-populated at the factory, of course) that describe the
current behavior of that particular battery. This allows more accurate
guesses about when the moment will pass when voltage will drop too low
to power the computer. (And yes, I know that it doesn't seem
particularly accurate even with this.)

There are lots of problems with expecting to have lookup tables for all
batteries. There will always be lots of them you missed. The list will
be obsolete the day after you publish it. And real batteries rarely meet
their published specs.
I think you're better off having generic parameters you can enter
(battery voltage, amphours, Peukert exponent) so you can trim them to
suit any battery.
Then (what the E-meter is missing), have your meter alter these default
settings based on what the battery actually does! For example, you
claimed it was 100ah at the 20-hour rate; it actually hit 1.75v/cell at
80ah at the 20-hour rate. So, amend the stored amphours accordingly.

Many companies will not write policies for GEMS.
State Farm does -- rec'd a quote for $84/month.
I hear USAA will write a policy for under $25/month.
I need your help with this .. who to call .. going rate, etc.
I'm in the Bay Area, CA.
Thanks,

Mark, Transmissions are totally different animals than ICE's. There are
no parts reciprocating at hi revs and they are inherently pretty well
balanced. Their bearings should have no problems with the R's that you are
talking about if they are in decent shape. Be sure that the fluid used has
adequate film strength.

Subject: Transmissions...
One thing that's bothered me... how can running 55+ mph in second gear not
be bad for a transmission? Has anyone had transmissions explode from
overrev?

It depends on which car is in question. Things like the rear axle
ratio, transmission gear ratios, and tire height.
My fuel car would do 35 or 45 mph(can't remember) @ 6,000 rpm in first
gear and 85 mph @ 6,000 rpm in second gear. It would have done more
but my motor was not good for more then 6,000 rpm.
26" tall tires, 2.73 axle gear ratio, 3.35 first gear, 1.93 second
gear. 4th gear in a 4 speed transmission and 4th gear in a 5 speed
are usually 1:1 ratio if you want to test out what it would be like if
you had no transmission and had a direct drive setup. Good to test if
your motor could move it..

If you want to play with high voltage, here's a relatively low cost device:

Their page specifies 108 - 132 volts AC.
http://www.iotaengineering.com/45spec.htm
I doubt you'd get much help from them though as the converter is not
specifically made to use DC in put. I do know that the 120vac units can take a
144 volt pack and to my understanding the 240vac units can take in the upwards
of 300vdc.
Tomorrow I might find out just how much tollerance there is with one. I
originally had planned a 192 volt conversion, but only found room for 144. In
the mean time I bought a 240 vac Iota, it's still there. I'm doubting it will
work, but I'm going to try it anyways before I run out and buy a 120volt
version. If it does work I'd be willing to bet the 120volt version would take a
fairly low input.

Roderick Wilde and others have had good luck with the Iota at as high as
240vdc. I'm getting one. Maybe Roderick will chime in on how he installed
it.

Ricky, If you end up not using your 240V Iota, I may be interested in
buying it from you. My Honda will be either 228V or 240V at the pack.
