As I wrote last week, I am selling off my old parts
that are just laying around in the garage. Before I
sell any of them, I need to be sure they still work.
In the past, I tested these EV-1's outside the car,
but I had trouble. Without a series wound motor
connected to it, it is difficult. Also, you can't
free spin a series wound motor, even if I had a spare
lying around. So, just connecting it to any old
series motor (unloaded) is a recipe for disaster.
What I did is just put a load between A1 and A2.
Then, I jumpered from T2 to A1. But, I think the
device is trying to read a voltage across T2 and A1 to
calculate how much current is flowing. With the
jumper, it is reading 0 volts = 0 current. It runs up
to about 20% duty cycle and then faults. Actually, it
starts pulsing the load at maybe 2 Hz. I believe that
is some type of fault condition.
I am testing with 36 V (3 x 12 V batteies). The load
I am using is a perm mag motor.
This is the exact same thing that happened last time I
tried to test outside the car. In the car it worked
fine then. I just want a way to test it outside the
car without having to uninstall / reinstall each of
them.
I'd appreciate any help. Thoughts on how to properly
bench test one of these.
Thanks,
Steve

Hey Shawn
Why not post them to the EV photo album?
BTW Love hearing about your awesome increases 8^)
If nothing else I'd be more than happy to post some
for you at my site, just let me know.

If people need to post pictures quickly and don't have any web space
handy, there is a service called tinypic ( http://www.tinypic.com/ )
which allows you to upload images via your web browser (no ftp client
or anything required) and then post the link here or wherever you want
people to see it, for free.
You many want to check the terms and conditions and so on, but I've
used it before and it appears to be harmless enough.
You can do the same thing with picasaweb, flickr etc but this involves
a bit of setting up first.
Be careful when pasting in the link that it doesn't automatically turn
your message into HTML as well - double check that you've got "plain
text" mode before pressing send.

Hey everyone,
There are some photos of AGNuS and OJ at
http://www.powerofdc.com/gallery.html
These were taken in June.
There is a video at the top of the page (taken in the pits) and at
the bottom are some close up shots of the bike and the dragster.
There are also photos of the bike and the dragster on the NEDRA site,
on the 100 mph Club and on the home page at various places.
At some point I plan to add more pictures of Shawn's great rides in
the NEDRA Photo Gallery

You cannot post photos on the list that is why we get
all those truncated messages but you can insert a link
to them. please e-mail some to me or just put them up
on one of you sites and refer us to them as I am sure
many would like to see both of your racers OJ and
AGNS. I am also looking for that electric lawn mower

I'm not sure about an SCR controller, but I know a good way to test newer
controllers is with a light bulb. It won't pull much current, but you
should see the light bulb brighten as you ramp the throttle up.

You can see the video here: <http://www.ap.org/>http://www.ap.org/ On
the bottom left hand corner it says AP News Minute. Click on that
then click on the Science and Tech tab, then you'll see the story
"Amp heads light up the strip" and click on that.
I really like Wayland's explaination of how the Zilla works.

Thanks Keith,
I'll send you some photos of both. The mower project has taken many
unexpected turns but all for the better. I'll have something I can
share with the public very soon.

Keith,
We are using aluminum 10" wide rims with 8" wide
slicks stretched out.
There are two in a tandem setup making AGNS a 3
wheel inline motorcycle.
Maybe the first ever on a dragstrip, but I doubt it.
By playing with
the motor magnets, tire diameter, and
series/parallel arrangements of
the motors we can switch between voltages rather
easily even without
actual gearing. I checked the 60 ft times for AGNS
from Saturday. The
best was 1.6 secs. Almost quicker than OJ. I have a
feeling she is
going to better this when given the added torque of
6 more batteries.
AGNS actually made her debut in south Florida. Her
best run that
night... 22 secs @ 67 MPH.
On not really sure how to post photos, but if you
can do it I will be
glad to email them to you.

Thanks Shawn I appreciate the answer but I guess I
didn't ask the right questions, I'll try again.
what size, type of construction Mags/Steel/Aluminum
what configuration I think you mentioned duel rear
wheels in one of your posts?
Tires slicks or street
batteries size do you change it when you up the
voltage(how are you able to use the same vehicle for
so many v classes?) If you were closer I would come
to see you race. I went to florida to see OJ but
you
didn't have AGNS then. Are you going to the NEDRA
finals on the 17th?

Hi Mark and all,
Have you tried to tune your motor for best amp draw? It just takes an
ammeter hooked to your setup while running. fix the motor at a steady
voltage then play with the timing untill you draw the least amps. That
should be the sweet spot. Lawrence Rhodes.......

I have low clearance above the shaft so if I can cut the sensor from
the bottom or out of the cup I can mount it below the supplied magnet
installed on the end of the shaft. I was just not certain if the
sensor is ONLY contained in the bottom of the cup where the wires are
molded into it.

Mark,
You can use any sensor that will pull the sense line low 4 times
for every revolution. No reason you couldn't simply mount the
magnet, and use a hall effect chip mounted next to it.
Alternatively, why not use a sleeve around the shaft?
Mark Dutko wrote:
Does anyone know if the zilla "cup speed sensor" on the cafe
electric site can be modified. If the pickup sensor is located at
the bottom of the cup where the wires go in (assuming this) I can
cut the cup off and place the sensor close to the magnet. If the
sensor is not there at the bottom and around the cup or something
odd like that, the cup will have to remain. I have a long shaft on
the motor and some clearance issues that prevent the cup from
being used. Anyone know where the sensor resides and how it works
specifically so I can start chopping...
Thanks,

All this talk of Viktor's new display has got me
salivating over a desire I've had for some time. I'd
really like a little display I can keep on my keychain
that will tell me how my car's charging is coming
along.
If a GFCI trips, I forget to plug in, or am just eager
for a full charge, a remote display would really make
my life easier.
I've got a 1997 Solectria Force with their Amp-Hour
display, just want some way to transmit and receive
the information.
Any ideas? Anyone do this before?
Thanks,
Todd Martin

Very interesting. I think they are doing a lot of things right.
1. They are leasing the battery, which in one leap eliminates about 95% of
the consumer concerns with every previous EV offered.
2. If range drops they will either replace the battery or give you a discount.
This leaves open the door for offering different batteries for people with
different range needs.
3. It knows how to speak Wifi, meaning it can tell the battery leasing
company when it needs help.
4. They're selling it online.
5. They're building to order. EVDLers my age or close to it will recall when
Detroit built cars to order; every option was sold separately, rather than in
silly packages. You didn't have to buy $500 worth of goofy fake plastic
spoilers to get cruise control (At least I >hope< that's what Think are talking
about.)
6. They're hooking up with Google.
I'm not so sure about this mumbo-jumbo about Dean Kamen's Stirling engine
as an APU, but I'll wait and see.
One minor but interesting point I noticed - Think seems to have lost its bang
(!). It used to be "Th!nk." Has anybody seen it? ;-)

Hello All ,
Does li ion technology really deliver its promises ?
I have chosen li-ions for my conversion
I took a look at the A123 , Thundersky , Valence , they have but very
cleverly hidden the prices and availability information from the sites
Has anyone who have used these products reported any explosions or
charging woes or so on ?
How are the track record of these companies ?(me being in India have
no clue about them whatsoever)
What kind of costs should i keep in mind to assemble a 330v+ pack ?
Are there any companies I missed that sell these batteries to us ?
Thanks a Lot

Lead time will depend on the work load in the queue, and whether the
adaptor is "in the can" or requires new design. We currently have 36
adaptor orders at various stages. We have have four machinists
working on them (three of them CNC). One is doing his first batch of
hubs for us, so has been a bit slow while he gets up to speed on the
design and gets it programmed. I just checked in an order of more
than a dozen motor spacer rings. Bryan Pikula's motor spacer ring
was in that batch, and his plate and hub should be in the next batch
(one machinist specializes in rings, another hubs, and two do
primarily plates and hubs).
In general, if the pattern is in the can, 4-6 weeks is good, although
it may get longer this time of year when there are a lot of orders
coming in, and machinists take vacations. There are also the wild
cards when a machinist throws his back out, or the lathe breaks
down. Sometimes there is a delay if the machinist doesn't have a
large enough piece of aluminum on hand, or if a pattern proves to be
too big for his machine and has to be reassigned to someone else, etc.
The only adaptors we attempt to stock are for the Rabbit, 914, and
Bug, as these are the fast movers. Of those 36 currently in
progress, half are one-offs, and one pattern is a three-off. If we
get an order for an adaptor that's the same as one already in the
work queue, we bump it up the line and have the machinist make two
(or three) instead of one, because it's more efficient. Outside of
the three fast movers mentioned above, we almost never get more than
three of the same thing at the same time. Of those 36 currently in
progress, 14 require some degree of CADD work before they can go to
the machinist.
If the adaptor requires design work, that will slow things down
because we only have one CADD designer (Mike) and he has many other
duties as well. We have tried without success to bring in a CADD
intern. If we have the transmission pattern on file, but not mated
up to the same motor, there is some delay while Mike takes the motor
from one file and the transmission from another and mates them up in
the CADD. This is the current situation on Damon Henry's adaptor.
If it is a completely new transmission, that will take the longest,
and how long depends on how many of them are in the design queue, and
how many other jobs Mike has to do. We are working on a new design
system that will speed this process up by getting digital at an
earlier stage, but we're not there yet. If the transmission has a
"floppy" mainshaft, it has to be centered and stabilized first, and
this adds some time.
We do not accept extra money to move someone to the front of the
line, as everyone is equally anxious to get their parts, and we don't
feel it would be fair to others who are waiting patiently.
I am sorry we have not been able to answer inquiries as promptly as
we would like. While we have an office assistant who can handle
routine questions, many inquiries require more technical answers from
me or Mike, and there are a large number of these coming in every
day. We prefer to communicate by email because we can send ten times
as many emails in a day as we can make phone calls - phone calls take longer.

I found this post on the NHRA website from 1998.
E.T. Brackets
The biggest news in E.T. Bracket racing is the development of rules to
accommodate electric-powered vehicles. Current plans are for the
electric cars to run in E.T. Brackets only, in their own eliminator
(similar to E.T. Snowmobile). Said NHRA Western Region Tech Director
Jerry Valentine, "It may be hard for some to believe, but we have these
cars showing up at NHRA member facilities ready to go racing. The
chassis are built according to NHRA guidelines, but we have nothing
that relates to a vehicle powered by something other than an
internal-combustion engine. So I've worked with several electric-car
organizations to come up with a basic set of rules that establish
minimum standards for the proper operation of electric-powered vehicles
and are simple for the technical inspector to enforce."
According to this, electric vehicles can't run in the same eliminator
class as other ICE cars or bikes of the same body/chassis style but
must run against each other only for purposes of elimination.
Has this been changed or are we out of luck wanting to run bike
eliminator with AGNS, Pro Eliminator with OJ, or Street Eliminator with
the Electropolitan?

Gulabrao Ingle asked:
"What does Ampere hour signify ?
does a higher ah rating equals more range , what is the ideal Ah
rating for an EV?"
Mick says: Roland Wiench's separate reply to your question is very accurate.
Here's some more information that may be helpful.
First consider the ampere: that's a measurement for electrical current, but
the amp is a real time value which cannot by itself represent a quantity of
energy (and cannot by itself even represent a quantity of power). The amp is
sort of like "miles per hour" as it is a real time rate of activity.
The amp-hour adds the element of time which takes us closer to measuring a
quantity of energy. The ampere-hour is a product reached when amperage is
multiplied by time. If 100 amperes flow for one hour, that's 100 amp-hours.
If 200 amps flow for a half hour, that also multiplies out to 100 amp-hours.
Battery capacity is often rated by the amp-hour so a battery with more ah of
capacity would also hold more energy, provided that the battery voltage is
the same.
Voltage must enter the picture before one can calculate a quantity of
energy. If the 100 amp-hours described above should move at an assumed 120
volts, multiply these two values together to calculate watt-hours. 100 X 120
= 12,000 watt-hours, which is the same as 12 kilowatt-hours.
I conduct energy calculations mostly in watt-hours instead of in amp-hours,
because the number of watt-hours under discussion always describes the same
amount of energy regardless of the voltage. I find that the watt-hour is
less confusing for my clients than the amp-hour, so I do amperage related
calculations in the background.
Gulabrao asked, "what is the ideal Ah rating for an EV?"
Mick says: It's impossible to answer a question like that because you have
not specified the battery voltage, the desired traveling distance, the
weight of the vehicle, or other important factors. Battery system design
includes many parameters which push and pull on one another. The amp-hour is
only one of those factors.
EVDL participants would be well qualified to address some of the other
parameters if they have the time to reply.

I have a related question that I have been meaning to write about:
I have a box of new Crydom (CSD2450) SSR's that I bought on eBay. The input
is 3.5-15VDC and the switched output is 240 VAC @ 50A.
I had planned on using them in my conversion for switching low power DC
circuits, such as horns, lights, radio's, etc. The problem, I have
discovered, is that AC switching loads will not work on DC. (I'm sure most
people on this board already that ... And are chuckling at my ignorance!)
Through experimentation, using a 12-v headlight, I find that the relay will
switch the light ON, but when the input is removed ... The light stays ON.
So much for that idea!
The purpose of this message is to see if there is some "trick" that I can
use to shut the SSR down, when switching 12-VDC loads ... Or should I start
looking for different SSR's?
Thanks,
Roger Daisley

You can get solid state relays from www.allelectrolnics.com for less than
$10.00 that may work for you. Yes, the ITE solid state relays I have been
running for 22 years every day cost me about $80.00 for a 40 amp at 100 VDC
back in 1985.

I may be wrong but I believe most of the raceways are
owned by corporations, patnerships or individuals not
NHRA. NHRA sanctions the events hence records as does
NEDRA but it does not mean they have to agree and have
the same rules. I have seen many vehicles run at
"NHRA" events that are not regulation vehicles. I am
not suggesting that we "piss" anyone off nor am I
living in a fantasy world and yes my vehicles may seem
like toys but one has to start somewhere and if our
toys get us noticed we may get the kind of money to
make bigger and better ones. Look what happened when
one person built the first monster truck. now it is a
whole industry. look what happened in the dune buggy
field. I am just suggesting that we may be able to
have broader rules. After all NEDRA is a separate
sanctioning body.

Regular US Mail works well; I think that airmail promises shorter
deliver times for only a modest increase in cost. The recipient will be
charged a $5-8 handling/brokerage fee depending on the particular grade
of mail service used.
If you want to ship by courier, then UPS Air typically works out the
cheapest since although it costs a bit more up front, they don't ding
the recipient for brokerage fees (which they will if shipped UPS
ground).
They don't bother collecting taxes or duty on packages valued $20 or
less and sent by mail.
I've got the shipper's paperwork handy from a piece of used test
equipment I purchased and had shipped here (Canada) by US mail. The
description is simply "used electronic test equipment", and it is
declared as "merchandise". I don't think that you need to worry about
declaring the country of origin as the USA to try to save the recipient
duty. A special NAFTA form is required for this, and most things don't
have duty on them these days anyway.
For a motor controller, I'd declare it as being a used car/automotive
type part since car parts are one of the classes of item that should be
duty exempt.
Cheers,
Roger.
