Just put up a few pictures of Shawn's OJ Dragster and Darin's
motorcycle from the Mason Dixon Dragway in Hagerstown, Maryland last
weekend.
http://www.powerofdc.com/pdc_fall_05.html
I'm glad I had the chance to go out and cheer them on. Shawn and Darin
covered all the technical details. But I have to say the weather was
absolutely perfect. It's not often we get 75 degree weather in
November. It actually felt like 80 with the sun out. The thing is 150
other drag racers felt the same way so it was really crowded. With the
OJ turning in an 11.5 the car was faster then half the gassers that
showed up and with 1.5 sec 60 ft time OJ was one of the quickest off
the line. And Darin's bike kept up with most the drag bikes there. The
first time Darin pulled up to the line the track announcer said, "I
don't know what that is, but I want one!"
The impromptu race really helped Shawn and Darin test their vehicles to
make improvements for the 2006 NEDRA season. Shawn will be racing at
the NEDRA Battery Beach Burnout organized by Shawn Waggoner in West
Palm Beach Florida January 21.
We may do this again next Fall. It will be called the NEDRA Power of DC
Fall Classic. Nothing fancy like the Spring Power of DC. Just bring
your EVs down for a few runs. Hopefully the weather will be in the 70's
again.
We are looking at either June 4 or June 11 for the next Power of DC. We
will have more information on the 2006 NEDRA schedule soon.
And we'll see yall in Florida January 21 at the Battery Beach Burnout.

I have a fluke. It stays mostly on the bench and I rarely use it.
I use it mostly to calibrate my every-day meters.
I think my accuracy is fine with a calibrated cheap meter.
Then again, I have one cheap meter for current, another for
voltage... all calibrated in the range where I am using
them if I care about accuracy.

Jerry, thanks for the heads up. I watched the trailer at
www.evconfidential.com. This should be a great film about the death of the
EV1. I can't wait to see it! I hope they show it in main stream theatres,
probably not though. It may get around like "The End of Suburbia" has

Hey all,
Just wondering what people think about various high performance motors. Most
prefer either ADC or WarP motors? Any thoughts?
And does anyone have the power/torque charts for the 9" motors for upper end
torque and power (1000 and 2000 Amps and 300+ Volts)? The only ones I can
find are for much lower values!!
Cheers

Hello David and All,
David Dymaxion wrote:
Great description! Were you able to adjust the field strength
independently of the armature? In other words, was it 12V-24V-48V
across both the field and armature together, or did the armature have
a different voltage than the field?
Yes, I was able to independently control the field. I used a fairly
simple control that consisted of a beefy TO3 package transistor on a
heat sink and a potentiometer that varied base current. I could 'dial
in' anything from about 12 volts to 48 volts. I also had a second way
of getting regen without playing with the field at all, and this was
simply a byproduct of my 3 step contactor controller.
The controller worked this way. At the first depression of the
accelerator pedal, a micro switch would engage 1st speed. The car would
start off with the eight 6 volt batteries wired in a series-parallel 24V
setup through a forklift nichrome resistor that helped reduce the
initial jerk of torque. The resistor 'had' to be cooled off, or it would
try to glow orange-hot. Though resistor control is considered primitive
by today's standards, it was only used for that initial take-off period
of a 1-5 seconds, so not too much power was dumped away in heat.
Speaking of that heat, I used an innovative way of cooling the resistor
off. I morphed a 120 vac fan from a desktop type small space heater with
a 12 vdc tape drive motor from an 8 track tape player to make a 12 vdc
fan (brushless DC muffin fans were not commonly available yet). The
input wires to the motor went across the resistor, as I measured
anything from 10 volts to 16 volts or so being dropped across it. Thus,
the 12V accessory power from the car was not used to run the fan (that
draw would have had a minimal effect on the 12V system, but hey, I was
still learning stuff). The hotter the resistor tried to get, the faster
the fan blew. The very hot exhausted air from this crude affair was
channeled into the car's weirdo heating system (the aforementioned
wasted motor exhaust air) to give extra heat for warming the cabin in
the Winter months.
I digress.....after the 1st resistor/24V stage, as you depressed the
accelerator farther down, a second micro switch fired another contactor
that would short out the resistor....now the car is accelerating harder
at a straight 24 volts.
The last 3rd speed was triggered at full throttle, when the 24V
series/parallel contactors would let go and the pack was reconfigured to
a straight 48V. Now, for the regen part....if you were flying down the
road at 48 volts in the shunt motor mode, then let up a little to
trigger the 24V mode, you'd get BIG regen. If you at the same time,
twisted the handy dash controlled pot. and dialed up full field current,
it would almost lock up the rear tires.
Thanks. I'm wondering if the
shunt acceleration might have been the same as the series with sepex
control.
No, it wouldn't have been. The shunt field windings were very fine wire.
Though I had actually turned the motor into a sepex type, to make a
really 'effective' sepex motor, the field windings would have needed to
be made of fewer turns of thicker wire. The Sepex motors used in the
more recent electric forklifts do have considerably smaller field wire
size than their series-wound brothers that use thick flat ribbon wire
for the fields that like the armature windings have to pass 500 amps of
juice, but the field wires are still fairly robust. The field windings
of a true sepex type are generally sized somewhere in between a regular
shunt-wound motor's fine strands of windings and a series-wound motor's
lower number of beefy ribbon wires.
As Lee said, our crude conversions based on these compound-wound
starter-generators served as our rolling classrooms.

Jody,
As I recall, I picked up a small 12V SLA battery for my electric
bike from Batteries Plus with that name on it (and could not find any
specs on the internet when looking for WERKER). I'd suggest looking on
the label to see if there is a secondary supplier (e.g. US Battery or
Trojan). I do know that Batteries Plus re-labels their Trojan-supplied
6V's.

I was down at the local Batteries+ store in Virginia Beach buying a new

a

Allan,
I don't know of any published research on this topic (though, I
expect there is much available). I'd just like to make a quick comment
on the language of the question posed to Fran below; hydrogen fuel cells
are electric generators, as I understand. Thus, the comparison would be
to various competing electrical energy storage devices, when it came to
cost comparison. (i.e. rephrase "fuel cell car over an electric car" to
"hydrogen supplied car over a grid-charged car" or similar).
The matter of cost comparison to the latter (i.e. the primary
modes users of this list rely upon) is highly variable. As the archives
detail, there is much debate on the balance between 12v, 8v, 6v and
total capacities among lead based batteries (esp. based on driving
profile), and much more when it comes to other battery technologies -
especially, when considering reliability!
I can think of several ways to approach this question - Let us
know how you fare.
Regards,
Craig

Subject: Electricity vs Hydrogen
Hello all,
I was wondering if anyone has any studies or papers in regard to the
questions below. I submitted my questions to Fran Pavley. A copy of
the email is below.
Dear Fran Pavley,
I am writing to you in hopes of getting an answer to my question. I
have been a follower alternative fuels for a number of years. In all my
studies and numerous papers I read, I have yet to find an argument that
supports a hydrogen infrastructure over an electric infrastructure. To
put it in simpler terms, why have a fuel cell car over an electric car?
Seems like the only hurdle with an electric car is range. This problem
is far closer to a solution verses all the hurdles that need to be
conquered with hydrogen. Some say the cost of hydrogen fueled car will
never be cheaper than an electric car.
Another question that will clearly point this out. Let's say we have
two equal amounts of energy, it can be solar or fossil fuel. One amount
is used to generate electricity to power an electric car. The other
equal amount is used to generate hydrogen. With both cars being equal
in weight and other parameters being equal, how far would each car
travel? My guess would be that the electric car would travel
significantly further.
I hope you can help me find the answer to my questions because as of
now, I am not convinced that a hydrogen infrastructure is the way to go.
Sincerely, Allan Alessio
AB 740 - Clean Air, Clean Water, and Coastal Protection Act
On February 19th, 2003, Fran Pavley officially introduced AB 740, The
Clean Air, Clean Water, and Coastal Protection Act of 2004. This piece
of legislation, if approved by the Legislature, would put a bond measure
on the ballot (most likely the March 2004 ballot) for $2.9 billion worth
of general obligation bonds for the financing of an air and water
quality and coastal protection program. Specifically, $500 million of
the $2.9 billion would go towards hydrogen fueling infrastructure and
consumer incentives for the purchase of fuel cell vehicles. This
legislation would also set the stage for additional hydrogen financing
by requiring a plan to be submitted to the Legislature that authorizes
the financing of subsequent fueling infrastructure development through
revenue bonds supported by a tax on hydrogen. EIN has provided, and will
continue to provide when asked, technical and educational support to
legislators and their staffs.
AB 740 was brought to committee on February 2, 2004. Despite receiving
overwhelming committee bipartisan support, it was put on suspense
because of the California budget crisis. The bill is expected to be
reintroduced in January 2005.

Well, you do have to agree with the ugly part in some cases. IMHO,
two of the ugliest cars ever made were the Honda EV1/Insight and the
Prius. Come to think of it, ya gotta admit that "underpowered" fits
far too many EVs.
Gotta quarrel with the last part, though. I'm pretty sure I'm
self-respecting and I wanna drive mine....

Yes; people thought it was a neat sound. "What have you got in that thing, a
turbine?" Ok in a truck or sports car, but it would get annoying in a family
car or "nice quiet EV".

Another great idea!
John's controller was very similar to mine. I also had a 3-step controller,
but with 36v and 72v. The starting resistor was really just a long strip of
steel packing crate banding. Cheap, but not as durable as a proper nichrome
resistor (I burned it in two on more than one occasion :-)
You're not supposed to drive with the starting resistor on for very long, as
it wastes a lot of power. One trick used in turn-of-the century controllers,
and a few semi-modrn forklifts, was to duct the starting resistor heat onto
the driver's feet or seat. If he wanted the heat, fine; at least the energy
is being put to some use. If not, the driver got a hot-foot or a hot-seat as
an indication to stop doing that!

(don't forget the "OT" qualifier here guys)
Tesla's Wardenclyffe Tower was supposed to be a world or at least
transatlantic broadcast station. People have also suggested it was part
of his wireless power transmission plans, communicating with aliens, or
a "death ray" (all elements of Tesla's work).
In fact no one is really clear on how that tower was supposed to work.
Its intended workings were not completed nor were they well documented,
contemporary and modern engineers haven't been able to make sense of the
purpose of its shape, and it was demolished in 1917.
The tower was the beginning of Tesla's period where he went mostly
crazy. Well, notably more crazy than before. Whether the failure of
the tower project drove him mad or he was already nuts and the project
was the work of a madman from the onset is a matter of speculation.
http://en.wikipedia.org/wiki/Wardenclyffe_Tower
I'm not sure how you could plan to reconstruct a functional tower based
on a design you don't even know the function of. Well, it's not my
money and it's sure to be interesting. Especially coming from these "I
have seen government laser satellites are controlling the weather" folks.

I just called my local battery store, and asked what they had
for golf car batteries. Trojan was the response, so I asked
how much the T-105 batteries are - $59.95 each, with some sort
of a deal for a quantity purchase - like 20.
I was also told about someone who has an S-10 pickup converted
that's in South Carolina and has dealt with these batteries a
bit, as well as some new ones from Trojan made specifically
for a certain golf car (can't remember the type!) - the
batteries are 12V, same capacity as the T105, but only around
80 lbs. Cost is not quite double the T-105 either. As far as
the guy I was talking to knew, there was no specific part
number, they're just used in this certain golf car in a pack
of 4.
Anyone know what these batteries are or who this mystery South
Carolina person is (are you on this list)?

Sounds like the T1275.

They have nowhere near the same AH capacity, and only slightly near the WH
capacity of a T105. They also don't list a 75 amp capacity, so I would be tend
to assume that the cycle life on heavy amp draws will be dismal.
Stay Charged!
Hump
(can't remember
the type!) - the batteries are 12V, same capacity as the T105, but only
around 80 lbs. Cost is not quite double the T-105 either. As far as the
guy I was talking to knew, there was no specific part number, they're just
used in this certain golf car in a pack of 4.

Are there a "high-range" and "low-range" sensors, as described here (see
page 4 for voltages)?

I can't seem to find a satisfactory answer to this question:
Is the Zilla HEPI input compatible with the twist-grip hall effect
throttles? These throttles appear to take +5 V and output a voltage
porportional to the throtttle position, simulating a potentiometer.
See:
http://www.users.bigpond.com/solarbbq/throttle/throttle%20how%20they%20work.htm
Standard Zilla setup is Curtis style -- that is, to use the
potentiometer as a rheostat (2 wires).
Only inkling I get from the manual is that the HEPI inputs are
(were?) called "Aux Pot +" and "Aux Pot -", which tends to imply a
rheostat-like function, though the manual mentions that 4 wires are
connected to the hairball, not the two implied by the pinout chart in
the manual.
No, the Zilla Hepi will not work with that.
For reliable security reasons (being able to detect opens and shorts
in the connections safely) the Zilla HEPI uses two hall inputs that
are offset from each other. It actually uses six wires, two of which
are ground that connect on two different terminals.
Sorry for not relying earlier, I've been missing much of the EV list
lately.

I looked around and found the Fiat to have no web presence, it is not in the
EV Album.
I took a bunch of photos of it while I was doing some repairs and upgrades
last spring, here are a few and some specs-

(with that Ford Escort you saw) gets lots of exposure for us too.

Hi,

Same thing happened to me. I think it blows from the surge when the
defroster blower is first turned on. I now use a 40 amp fuse.
Yes, I too had troubles with the output fuse on my DCP DC/DC converter
randomly blowing a couple of times. Interestingly enough, I recall the
DC/DC converter being lightly loaded at least one of the times that the
output fuse blew.
Of course, this turned out to be the least of my problems with my DCP
unit, as it later blew itself up (rather dramatically) and thus far has
been unrepairable...

Even if that was more than 25 amps, shouldn't the DC/DC be enforcing a
very strict current limit on it's output to prevent blowing itself up?
If so, then it would seem that there is no reason the output fuse should
blow even if you are trying to pull more than 30A from it. Unless
perhaps you throw on a heavy load and the DC/DC can't/doesn't throttle
back the PWM duty cycle fast enough, allowing the output current to
surge briefly until it can get things under control again?

Justin,
Try contacting Dave Mason at US Battery. He gave me a great deal on batteries
for my car last year.

Hi All, I've been asked to ask if anyone here has good contacts for buying
Trojan batteries in or around Compton Ca. The requester has contacts in
Compton who periodically send shipping containers to New Zealand. He is
hoping to import them directly from the US as anything but the locally
manufactured SLI batteries are very expensive here. IE Optima or Orbital
$400ea, generic GC $200+ea. Contacts for USBattery would be good too. I
recall seeing info before but never saved it as i didnt expect to have a
use for it. Thanks in advance.

I was recently in Sam's Club and saw an orbital
battery on the shelf:
http://search.samsclub.com/eclub/search/search.do?simpleitemtype=0&action=search&searchtype=simple&simplesearchfor=nascar+battery&x=0&y=0
I understand Exide makes their batteries, so it's
likely a relabled version of one of these:
http://www.exideworld.com/products/trans/na/automotive.html
Anyone know anything about them? Would either be a
likely candidate for an EV?
Ken

i submitted the data to the ev photo album twice, but it didnt make it
in somehow. one of these day's ill post it to my own website, i keep
waiting, because i think i'll just wait til i make one more change... ;)
