That would be battery amps in this case.
Its an Auburn 144 VDC 800 amps maximum, but that is a good idea if I had
the right controller.

Yes; but it does it 120 times a second (at 60 Hz). That is so fast that
your muscles don't have time to relax during these brief instants of
time. And, though we say it is 120 volts AC, the peak is actually around
170 volts.

Bruce,
This is a great idea, in that you can also keep the charging battery(s)
immersed in ice water to keep their temperature under control!

All,
Speaking of the Plasma Boy and camera flashes, I remember one time when I
was reconnecting my pack of YT's in the RX-7 and John Bryan, who had
stopped by to help me reinstall them, left the shop and went home to avoid
distracting me while I installed the interconnects. As many of you know,
Bryan was the person that handed Wayland the last interconnect, which he
fumbled and shorted out his pack with, causing the "event", which Bryan got
to witness first hand!
Anyway, I wanted to mention that a couple of days ago after removing the
last of the one inch thick sheets of insulation in the S10 (which turned
into a multi-day event!), and while reconnecting the last four batteries of
my pack of floodies, my new cell phone vibrated on my belt and scared the
living crap out of me, as I thought I was being shocked!

This simple regulator is not intended as a wonderful do-it-all miracle
cure. It is just a quick-and-dirty system, intended as a cheap
alternative for those who would otherwise have *NO* regulators!
Oh very understood. I'm really trying to figure out all of this stuff
for giving AGMs the best shot at long life. And some of the info out
there is quite contradictory.
Just to understand: The regulators start to bypass at 13.6, but continue
to allow some current to the battery up ito 15 volts? Or do they just
bypass all current around the battery?

Lee, no matter what I hear about cheap regulators, I keep thinking that your
on the fly balancer idea is still the ideal support mechanism for EVs. Sorta
like a truss. Support the weak and prevent imbalances as you drive makes the
most sense at least to me. We talked about this years ago, is this still
alive? Are you doing anything with it since the last batch of boards were
made and sold? Final question, would it be possible to use mosfets to handle
the high amperage switching rather than relays? Seems like a good way to
reduce the size, mechanical complexity and cost. Might be possible to make
those balancers in an 8 pack format with edge connectors so they could be
daisy chained like leggos? David C.

It isn't one-of-a-kind. I know - I have one, too. The eBay price is
less than what I paid for mine, and a lot less than what they cost new
(they were originally over $30,000) There is a third in a tZero in
Northern California, and ACP built a number of them into cars
custom-made for people who wanted a specific car (VW Golf among them)
converted.
Support is only a phone call / e-mail away. Start with
www.acpropulsion.com 's "How to Contact Us" links... they're pretty
responsive.
jorg
ps In case it hasn't mentioned, this is the same controller/motor combo
used in the tZero. I'm building mine into a 914, which is notably
heavier than a tZero but, hey, I can live with 0-60 in 5 seconds instead
of 4...

I can't say for certain, but Tom's description sounds exactly like AC

I just wish they'd offer a Li-Ion option, for those who wouldn't mind
paying an extra $30K for the extra 200 miles.

Has a date been set for Woodburn 2004? Nedra.com is still listing TBA, but
I thought the track bookings generally were done a year in advance.
The track doesn't list it on their schedule, (not that I would expect it)
but there is a non-point Junior dragster event on Sep 5th that might be
running alongside.
I (and probably the rest of the Austin contigent) would like to make
travel plans early this year. (Bringing toys means slighty more planning
than just hopping a plane...)

I followed the eBay URL to the seller's web site and came across this paper
describing the project these componenets were in:
http://www.idahofuturetruck.org/previous/frames_version/FT_SAE01.pdf .
Turns out it was a Chevy Suburban with a 1.9L Passat Diesel engine and AC
Propulsion hybrid in line drive train. On page 14 is a prototype vs
estimated production cost table broken down by major components.
The home page has additional papers and information. Looked like a fun
project with lots of data.

I notice that one of Steve Clunn's rigs in the EV Album uses a computer

If a car never had an ICE in it, is it a conversion? I would say no since
technically, it was not converted from any other propulsion method.

hi there.
my citicar brakes failed yesterday (luckily only rears, thank god for
dual master cylinders), so I was going to hook up the plug braking wire
on my curtis 1209 controller as another backup.
Is there something bad about doing this? I heard something about not
doing it on street EV's, while scott hull does recommend it on his
website about citicars he's restored.
thanks for your comments.

Allright,
It is monday, and I have a question to pose that has

Why is battery capacity usually specified in Amp-hrs ?
Doesn't it make more sense to talk about watt-hrs when
talking about energy storage capacity ? Wouldn't using
Watt hours would make it easier to compare batteries
of different voltages and internal resistance.
After all, Amps don't propel me down the road, watts
do.
Is it convention to rate capacity in amp-hrs just
because the normal test is a constant current
discharge, so no additional instrumentation is
necessary to calculate amp hrs (whereas a voltmeter
and calculator would be needed to get Watt-hrs).
just curious because it has been bugging me as I dream
about new batteries and high energy density.

I've used ADC and Warfield motors over the years and havn't had any
problems, have about 50k miles on my 9" warfield (ADC copy) and put 85k on
my last 8" ADC motor with original brushes bearings.

Thanks, Jude. I will probably put it up later this week - not feeling too
good at the moment. Sold my Escort, EV, though, so now I can get planning a
new conversion. That's got me smiling!

Nice project. And an interesting quote on their choice of battery cables:
"The batteries are connected in series by a high performance wire. The
wire is called Prestosil and meets ASTM B-8, B-173, B-f193. It is a new
product from Prestolite Wire designed specifically for hybrid and
electric vehicle applications. Prestosil is rated to carry up to 440
Amps on a 1-gauge wire. In order for standard wire to carry the same
Amps, it would be have to be 2/0 gauge, which is considerably heavier.
The weight savings from using the smaller wire was 15 pounds within the
battery boxes and 22 pounds for the entire vehicle."
Assuming Ohm's law hasn't changed, does this mean this wire just has
super high temperature insulation and they didn't worry about the power
wasted as heat?

Just to understand: The regulators start to bypass at 13.6, but
continue to allow some current to the battery up ito 15 volts? Or do
they just bypass all current around the battery?
Lee's reg starts bypassing some current at about 13.6 volts and
bypasses a peak of 1/2 amp (more or less). The circuit is in parallel
with the battery so the battery is charging and the reg is bypassing
at the same time (because if current was no longer flowing into the
battery its voltage would drop below 13.6 volts).
Rudman regs have a hard turn on point (user adjustable) and bypass
whatever their load will pass at the set voltage point. This can be
more than the charging current (most often near the end of charge) so
they can not only take all the charge current off of that battery
they can also discharge is a little (causing the voltage to quickly
sink below the set point, turning the reg turns back off).

I looked up Presosil on the net and most of the articles talk about it
as an **insulation** for spark plug wires. So as you say, it is
probably a better insulator against the heat. Although they could have
found a better conductor.

Update.
I broke Gone Poastal.... the right inside drive belt went at 1250
amps....
The front drive won't make more than about 750 amps, for some
reason.....OT!!!! Help!..
I now(this Monday morning) think the front Zilla thinks it's in
reverse..... and it's not, so I get reverse power levels.
Rod and Don are going to put on our last semi OK belts, I am going to
turn down the back Zilla to 1000 and and get the front to smoke rubber
or break half shafts... Which ever comes first....
Off to PT, Sorry charger customers, one more day in front of the TV crew
and I will be back to toss Green boxes together.
Later...
Madman... With a new Kevlar necklace....

As long as you understand that all the braking energy is being turned into
heat in both your controller and motor and plan accordingly you should be
fine. Certainly it would be fine as an emergency backup.

Subject: plug braking OK on street EV?
Date: Mon, 29 Mar 2004 02:30:21 -0800
hi there.
my citicar brakes failed yesterday (luckily only rears, thank god for dual
master cylinders), so I was going to hook up the plug braking wire on my
curtis 1209 controller as another backup.
Is there something bad about doing this? I heard something about not doing
it on street EV's, while scott hull does recommend it on his website about
citicars he's restored.
thanks for your comments.

Sorry about the foul -up on pictures They are NOW ON Line and
connected to the web site.
A charter member of the Seattle EV Association, Byron Verbon, a retired
Industrial Arts Teacher, is selling his Fiat 850 Spyder EV.
The car was put together about 24 years ago. It is a two-relay
switching speed control.(I think) The batteries are LONG SINCE S H O T
butI believe there are 16 - 6V for 96 volts.( I think) The on board
charger is a Lester (boat anchor) type ( I Think ) But check with the
owner....
Facts and figures ( Pictures ) can be seen at :

Does this statement indicate that Discovery is doing more filming for
the pilot, or has the show been picked up for more episodes?

I think it is just the traditional method. Watthours would work as well,
but require more calculation.

That's about the only thing it can mean. Unless it's silver wire
(unlikely) or superconducting wire (VERY unlikely)!
Personally, I think flat copper strips (bus bars) are a better choice if
you want light weight and don't care about the resistive losses. They
have a much larger surface area, and so can handle far more current for
a given cross section. You can insulate them with sleeving, if desired.
