The decision to write this POST came hard. That there has been no
response or dialog... makes me feel like I have been on a soap-box
delivering an monolog, and no one is there to hear it...
I guess I thought that this E-Chair EVent with a $1000. purse, and some
BIG NAME guest drivers would have generated a few responses, or at least
some comments.
But as I go over the EVDL for the last 3 days... it is as if the
original POST had never been sent.
I know the whole idea might be frivolous, but the time and effort that
folks like Cloud, "Father Time" and others have put into these machines
at least should be respected, and worthy of comment.
I know for a FACT that some heads will TURN, when these vintage road
racing types see the performance of these vehicles. These guys spend
(collectively) MILLIONS of DOLLARS on these vintage race cars just in
the Pacific North West alone. And there are groups like this all over
the country. And for us ( the EV Community) to rub elbows with them IS
important.... and meaningful. Just to educate them about it all. To
CHAT about NEDRA, and to reflect on the road racing electric cars of a
few years ago..
It is as important as all the discussion about EV Drag Racing !(hundreds
of POSTS at last count) and for the same reasons. To educate the
un-educated. Electric POWER R U L E S !!!

Hi Steve
I will be there with the Crabtree and Cloud camps.
I am not sure, but did you actually post all the details of this to the
EVDL?
Like... where, when, who, and what?
I searhed your posts back thru March and did not find it.
If those on the EVDL had known about this from the beginning there may have
been more interest.

Nice job on the battery cleaning. The boxes look powder coated. What
material did you use? Thickness etc. The straps look like copper with
tinned ends. I see you opted for thinner and thick interconnects. What
coating did you use? I'd like to know how they work out. Very nice indeed.
I'm thinking about my use of the BB600's. Lawrence Rhodes...

Pictures of the (mostly) installed BB600 NiCd's in my Yellow Sparrow:

Nominal Pack voltage of 164.4v.
I took it for a short drive to make sure everything worked, and it did!
Things Yet to be Done:
A) Lower the bottom of the under-seat battery box by 1". This will
involve carving out the fiberglass bottom and some of the foam, then
putting in a new fiberglass bottom.
B) Install battery hold-downs.
C) Build a quick-remove tray in the front for the PFC-20 charger. (It has
to be easy and quick to remove so I can water the NiCd cells easily.
D) Install my Battery Monitors to warn me when any cells are low so I
don't reverse them.

This guy is excited about electrics and is trying to discuss

Is his goal a >practical< one at this point? Probably not. Is it
>possible<? We don't really know because no one has tried it yet and
talked about it, as far as I know. But given the advances in batteries
that are occurring and the accelerated rate of change we are seeing across
the board in materials science, it might not be an impractical goal for
long.

Hey Steven,
Ive been patiently waiting to see pics, video and most important to me info
from FT, as to how the motors (ones he has never used before) perform. I know
for fact that he was excited about the building of the machine and in fact put
off his VW racer to get a chair up, to meet the date. I doubt the money or the
drivers were why FT wanted to do this, and drifted more to Ive never done
that! And just to have some fun.
Although this is tongue-in-cheek, meant to be fun event I cant wait to see the
results. I hope someone up there will take the time and effort needed to
record the event so that people interested (like me) can go to learn and have a
few chuckles. I see this as a demonstration that an EV can do just about any
job given. Im not sure how they are being driven now, but an EV driven float
for parades seems another fun way to hook others to EVs.
As there had just been a volley of race / range interest debate going on, I
opted to bow out from a post to yours. Hopefully this was the same for others.
I believe your post was a case of bad timing.
Just wanted to let you know that there are those that are interested, and
please link pics.

I'm inclined to agree with you. Racing and talking about racing distracts
people from issues like battery problems, charging time, range limitations,
costs, etc.
I'm probably not the right one to talk to people about EVs. I'm not a high
pressure salesman. I talk to people about both the positive and negative
aspects of EVs without exaggerating the positives or dismissing the
negatives. My goal is to help people understand EVs, not push them to get
one.

Tom Shay Said.
People
I talk to seem to already know most of the basics. They know batteries
are heavy, slow to recharge, and won't go very far between charges.
They do know that EVs are quiet and non-polluting. About all that's
left for me to tell them is that EVs are a lot faster than golf carts and
technical details.
I think this is exactly the thing that the race crowd dispells. Certainly
you car doesn't have to be slow or take a long time charging. If you have
enough money you also won't have to not go very far. Maybe you're not the
guy that should be talkiing to people about EV's. Maybe 10 years ago but
not now.

I am starting to crimp up my cables and am wanting to know if the +A1
and -A2 are significant?
I assume the B+ from the pack goes thru the fuse and to the -A2 and that
the +A1 go on to the zilla B+. I think it matters since it has mag blowouts.

I like it! I like it! I did consider putting a little windmill on my
Ranger pickup conversion as a joke. This guy is serious with a
9-foot diameter propellor and a homemade alternator. The 35-year
old pickup complete with a dog in the bed is also a nice touch.
He's doing this to test his windmill, but think of the possibilities for
an EV. The unit could be run as a generator for charging the
battery while parked and while driving. It could provide
regeneration. It could be run as a motor to help the truck climb hills and
get
a way from stop signs.

Wondering if one was to put my trucks radiator back in and used a inline

different pumps to make my eyes go buggy. Your idea has crossed my
mind. But I don't think those little washer motors are meant to run
continuously, and I don't think they would meet the flow requirements
(Otmar informs me that 2GPM as listed in the Zilla manual is actually a
bit high - 1/2GPM would suffice in most circumstances). Pumps that are
doing that sort of flow have 3/8" outputs or larger. The small diameter
tubing on the washer motors leads me to think the flow is quite a bit
lower than that.
Ryan, you're right. I bought a window washer pump from an auto parts store
several years ago when I was trying to make an ice water air conditioner
(you know, ice chest full of ice water running through an oil cooler with
fans strapped to it -- hasn't everyone tried this?). Though the packaging
on the pump clearly stated "intermittent duty only" I figured "heck, this
thing's going to be running in ice water, it couldn't possibly overheat".
I put it in a ziplock bag with the leads and tubes sticking out the top,
and hung the bag into the ice water.
The motor ran briskly for about 3 minutes, putting out an impressive flow
for its little 1/8" ports. Then it siezed. I checked the motor afterward,
and it was very hot. The ice water kept it from melting the bag, but
didn't protect the motor.
I don't know what it would have done on 5V, but I doubt it would have
moved enough water to cool a Zilla. (It may not have been, even at 12V). I
ended up using a 12V marine bilge pump, which worked well.
I totally agree with Bill Dube on this one though -- I'll be using a
MaxiJet on my Zilla. We did this with Mark Farver's MR2, and all you can
hear is the water moving.

I got the impression that the wind from driving was supposed to generate
power to make it go. Meethinks somebody needs to go back to high school
physics to remind him of why perpertual motion machines don't work...
You can generate power while stopped but any additional power while
driving comes entirely from the motor minus an efficiency penalty.
Props aren't all that efficient. They can get up into the 80 percent
range for particular speeds. Basic, nonscientifically tuned, general
ranged fixed pitch props can be more like 40%.

HI all,
I would like to know people's opinion on the type og gauges they prefer.
Digital or analog especially for the voltmeter. I plan to have voltmeters on
each of my SCS225 batts. 6 of them. I don't know whether to go digital in
terms of LED or analog. Prob don't have room for analog, as there are a few
of them. But i know they are sorta more sturdy type gauges. The main battery
pack will be analog and also digital because of my computer display from the
alltrax controller.

I didn't get to see the web site because of the flash but I can hazard
a guess. If they've figured out a way to disperse active material
onto the huge surface area of activated charcoal, then they could
produce a battery with very high energy density, very high power
density and a great resistance to polarization. Am I close? :-)
About patents. The first thing I do when I hear about a company
releasing a new technology is to go to http://www.uspto.gov, do a
quick patent search and plug the company name into the "assignee"
field. If the company has any patents assigned to it, they'll kick
back. In this case, "Firefly" returned nothing relevant. If someone
who is willing to let FLASH execute on his computer can glean any
other company name, I'll do so more searching.

It performs a similar function - opening up the matrix, de-densifying

Dunno about that. Probably not. BTW, I recharged both Zinc Carbon
and alkaline batteries when I was a kid in the early 70s. ZC worked
OK with a pulse charger that applied a brief negative "depolarizing"
pulse. Much better results came from the alkaline chemistry of the
time. Those batteries contained mercury which may or may not have
affected the rechargeability. In any event, I recall using a set of
alkaline D cells in an old Zenith WaveMagnet shortwave radio for
several years, recharging them every couple of weeks in a modified
"dry cell charger". Sometime in the 80s, Mallory/Duracell figured out
how to stop that, for the charging suddenly quit working. I haven't
tried it since.

Again, no. Some simple calcs will show the error of that thinking.

Oversimplified. The flywheel inertia is used to tune the rate and
quality of power delivery. (assuming the vehicle has enough power to
even matter) Too little inertia and the power application is difficult
to control, particularly in marginal traction situations. It makes
the power jerky and is hard on the gear train.
In an EV, some compensation can be done in the controller,
particularly if it has velocity feedback (RPM sensor) but a little
inertial mass can take the place of a lot of electronics and firmware
toward smoothing the power application and removal.
These rude and crude ADC and similar series motors already have enough
mass in the armature for the purpose so yes, one can pretty much
remove the gas engine flywheel material with satisfactory results.
OTOH, if one is working with a light rotor AC motor, a BLDC motor or
pan motors (ETEK, etc), the flywheel tuning is just another part of
making the setup tractable.

Both, whenever I can have them. Digital for recording the data with
precision and analog for the glance-out-the-side-of-my-eye monitoring
while underway. I like to use the old racing practice of arranging
all the gauges so that their pointers are near vertical when
conditions are normal. A quick scan for "all conditions 12 O'clock"
is all that is needed.
If I had to go with one or the other, it would be analog.

I think this battery was actually developed at the Caterpillar R&D lab
in Peoria, IL. Then some how, the employees that were involved spun
off this "Firefly" company.
I think this is the patent for the battery: 20040002006

If someone can't get the link to work, here's the summary:
Battery including carbon foam current collectors
Abstract
A battery having a current collector constructed of carbon foam. The
carbon foam includes a network of pores into which a chemically active
paste is disposed to create either a positive or negative plate for
the battery. The carbon foam resists corrosion and exhibits a large
amount of surface area. The invention includes a method for making the

I am taking a Lithium Battery poll to update the EV FAQ hosted by
EVParts.com I will be collecting this information and David Brandt will
edit and put it on the EV FAQ.
Here are the questions:
Lithium Battery Manufacturers
-----------------------------
1. Do you know of a Lithium battery manufacturer who sells EV specific
batteries? What is their name and website?
2. Do you know who can they be ordered from? (e.g. is there a north American
distributor?)
3. If possible, please list some specifics in terms of capacity, BMS, weight
and price.
Lithium Battery Users
---------------------
1. If you use Lithium batteries in your EV, what brand, type and size?
2. What size is the pack, and the type of your EV?
3. What do you use for a BMS?
4. Do you need other energy technology to supplement Lithium? Super Caps,
Lead Acid?
5. Other comments about using lithium technology (experience, safety,
quality, would you do it again, etc.):
thanks

Robert, if you use bar graph digital gauges, one for each battery (like an
equalizer) you will be quickly be able to tell if one battery is lower than
the others. If you are able to get your hands on colour gauges, then it
will be even better. (e.g. see all green and all is AOK).

Subject: Digital or analog gauges
HI all,
I would like to know people's opinion on the type og gauges they prefer.
Digital or analog especially for the voltmeter. I plan to have voltmeters on
each of my SCS225 batts. 6 of them. I don't know whether to go digital in
terms of LED or analog. Prob don't have room for analog, as there are a few
of them. But i know they are sorta more sturdy type gauges. The main battery
pack will be analog and also digital because of my computer display from the
alltrax controller.
Cheers

Steve, I think you or Crabtree or Cloud or somebody should post
a message with more information and links to plenty of good
pictures to get people interested enough to respond. In other words,
tell us more.

Subject: E-Chair Lazy Boys - Monolog or Dialog ?
The decision to write this POST came hard. That there has been no
response or dialog... makes me feel like I have been on a soap-box
delivering an monolog, and no one is there to hear it...
I guess I thought that this E-Chair EVent with a $1000. purse, and some
BIG NAME guest drivers would have generated a few responses, or at least
some comments.
But as I go over the EVDL for the last 3 days... it is as if the
original POST had never been sent.
I know the whole idea might be frivolous, but the time and effort that
folks like Cloud, "Father Time" and others have put into these machines
at least should be respected, and worthy of comment.
I know for a FACT that some heads will TURN, when these vintage road
racing types see the performance of these vehicles. These guys spend
(collectively) MILLIONS of DOLLARS on these vintage race cars just in
the Pacific North West alone. And there are groups like this all over
the country. And for us ( the EV Community) to rub elbows with them IS
important.... and meaningful. Just to educate them about it all. To
CHAT about NEDRA, and to reflect on the road racing electric cars of a
few years ago..
It is as important as all the discussion about EV Drag Racing !(hundreds
of POSTS at last count) and for the same reasons. To educate the
un-educated. Electric POWER R U L E S !!!

I got the impression that the wind from driving was supposed to generate
power to make it go. Meethinks somebody needs to go back to high school
physics to remind him of why perpertual motion machines don't work... You
can generate power while stopped but any additional power while driving
comes entirely from the motor minus an efficiency penalty.
Danny -
I read the entire page, and he never said anything that would lead me to
believe what you suggest.
In fact, he clearly stated that he uses the pickup to TEST the wind turbine'
performance at varying speeds.
This guy did a lot of good work and obviously knows his stuff.
Don't belittle him and his effort based on a sloppy reading of his site.

This is your reminder for the September meeting of the Electric Vehicle
Society of Canada. As usual we will meet at 7:30 PM in Room B204 of
the Ashtonbee Campus of Centennial College.
The Campus is at 75 Ashtonbee Rd. which is on the West side of Warden
Ave. North of Eglinton Ave. The college has instituted a $5.00 parking
fee but there is also parking on the South side of Ashtonbee Rd. Join
us for dinner at 6:00 PM at the Wexford Restaurant on Lawrence, just
East of Warden, if it suits your schedule.
I hope to see you at the meeting.

Neat article. I don't think such a thing should really cost $500 in
parts. That's about $40-$50 in parts before casing, not including
design and labor. Potentially less. The use a Basic Stamp is a very
poor choice for one.
The hokey part is that optoisolators generally aren't designed for
analog. The gain is a bit inconsistent and depends on temperature, but
if they're all physically grouped together and their temp can be assumed
to be similar then the relative accuracy is not that bad and the
relative accuracy seems to be the important part. Calibration should be
handled on the microcontroller, not on the board. This saves a bundle
in parts for one. For another, if you can simply make a test harness
that wires them all in parallel and press an internal "Calibrate Me!"
button then it can sample all the inputs and store compensation data
without the operator having to twiddle a bunch of pots.
