Still need a way to EXHAUST the 156 dg HOT side in summer. Much like the 3 port
issue, but that is what I have used before with success, the peltiers.

I used belleville spring washers on my lugs. They seem
to do the trick. The difference between them and the
regular lock washers is that they apply force evenly.
There is a link below that might work, if it doesn't,
go to mcmaster.com and type in belleville in the find
box.
Good luck,
TiM

200 hz. A cycle ends up where it started ( there and back again).
6000 rpm is 100 rps, so 400 changes per second and the cycle is
complete every two changes.

Lee,
Could an MOV/varistor or something similar be used to put across the
fet driver output lines to short and blow the fuses during an over
voltage condition? It's a 3708 driver on the main board driving a pair
of IGBT's on the charger board. There is a wiring harness in between.
Easy to put a board in between them.
The devistation to our boards is amazing when this failure happens.
Could this same setup be applied to the 120/240 vac lines using an
mov, varistor? Current draw is not suppose to be more than 2 amps.
Saving the board components is not an issue. Keeping the board traces
from smoking is.

1) Working with SONY Pictures Distribution representatives here in
Seattle, we...The Seattle EV Association, have been granted (up-to) 100
tickets
(50 two-person-passes) to an ADVANCED Screening of "Who-Killed the
Electric Car" to be shown on July 11th, 3 days prior to the Public
Opening...!! We are to dream up various contest, drawings, etc. to get
these tickets into worthy hands.
They are doing the inviting of Enviro-Types, Politicians, Dignitaries,
and the MEDIA... So we are free to use our imaginations !
One of my first ideas was to have folks enter a short paragraph. . "Why
I would LOVE to have an Electric Car" All winning entries would get
tickets.
2nd Idea, would be to hand over some of these tickets to our Local PBS
station for Distribution in some way that THEY would think worthy.
AND I am sure others will have other ideas.
Only Problem.... July 11th is not too far away. So it can't be too
fancy or Hard to implement.
ITEM 2) Everyone in our EV and PHEV community should take a close look
at House Bill 5538 (formal Name)
Plug-In Hybrid Electric Vehicle Act of 2006

Things are starting to COOK... Im off this afternoon for a radio
interview with the Sandusky Radio Network.. ( 5 radio stations here in
the Seattle area.. I'll let ya all know when the program will air...
Till then...

Another source for modules (surplus)
http://www.mpja.com/listitems.asp?dept=60 I am going to end up making a
custom waterblock (or salvage one off of something else) and mount the TEC
and the cold side heatsinks up in the stock airbox. Then run the hot side
coolent lines out the holes where the AC lines ran and hook it up to a small
pump, radiator and fan. Not exactly sure on size but hopeing that the stock
heater core will work else I have the factory radiator still and can get it
involved as well.
Later,

When I started my conversion, I decided to migrate my static pages to a
blog, to make updating more convenient. I found a blog that I liked so
much, I decided to become a developer. When I'm not doing EV or family
stuff, I'm doing Serendipity development (www.s9y.org).
There is a service that will provide a free Serendipity blog for you,
too: www.supersized.org.

Okay, I've searched all 24,039 unread messages in my inbox, and all the
archived messages, and I'm still a little confused.
I bought the PFC-20 and Rudman Mk2B regulators. I'm quite paranoid
about killing off my batteries, since this is my first EV. The
batteries -- 12 Optima D34 YellowTops -- just arrived, so I'm working on
installing everything.
The regulators will go right on top of the batteries, and the
instructions clearly show that I can wire the regulator B- and B+
directly to each battery. Cool.
I'm a little confused over the bus wiring. I'm going to pick up an RJ35
stripper and crimper tool, but the regbus connectors appear to have 6
conductors; I've never seen a telephone wire with more than 4. Granted,
my experience is very limited. Nonetheless, can someone advise me on
what kind of RJ35 wire I have to get, and how to lay the wires in the
connectors?
As a follow-on question, what's that 7-pair header (J8, I think?) doing
there? The only docs I can find on the Manzanita Micro site appear to
describe a different version, since mine don't separate Sense jumpers.
Thanks in advance,
Judebert

Steven,
You ain't kidding things are starting to cook! That bill is a great
acknowledgement that someone is paying attention. Too bad it doesn't
have an EV provision. But then again, the technology should spill over
to EV's.

Gail
G'day Gail, and all
The problem that I have found with reading the numbers is that they are a)
in very high-contrast to the background (dim numbers in a dark box against
a bright screen) and b) the "hard" number (inserted to make it hard for a
computer to intepret it) is often tilted and/or fades, so that a 1 or a 2
could be mis-read as a 7, for example.
I sent an email to the site owner, & he basically said that they had to do
this as someone went to all the trouble of writing a computer program that
would vote, read the number, confirm it, change IP address and do it all
again. Remember a couple of months ago a couple of vehicles that'd jump 800
votes a night, then once it was ahead would get no votes for a week? So
they had to use a display form that computers find almost impossible to
interpret correctly.
He could do something about the brightness pf the page background, though.

One of the YTs that Ralph Merwin generously donated to my EV project
bears the scars of having had the reg mounted right on top of it. I
don't know why the reg misbehaved, but it nearly melted through the top
of the battery before Ralph caught it. Mount your regs *near* the
batteries if you must, but don't mount them directly on the battery if
you can avoid it.

What the heck is RJ35? You either need an RJ12 (6-conductor,
phone-type) or RJ45 (8-conductor, PC network-type) connector.
Double-check the reg documentation to confirm which you need before
buying; if you have PC network cable handy, just try plugging it into
the regbus jack; if it fits, you can use common RJ45 network connectors;
if it is too wide, you need to use the RJ12 phone connector.
You should be able to find 3 or 4 pair phone cable just about anywhere
(such as Home Depot, etc.), and you can definitely use CAT5
(8-conductor, 4-pair) network cable.
Whichever cable you choose to go with, I would strongly suggest that you
use stranded, rather than solid, cable as it will better cope with the
vibrations/flexing in an automotive environement. You need to ensure
that the connectors you buy are for stranded cable if you use stranded
cable, or for solid cable if you use solid cable.
Useful information about the RJ connectors and links to an 8-conductor
flat phone cable can be found at:
<http://en.wikipedia.org/wiki/RJ-11>
Note that it doesn't matter which wires you connect to which pin of the
connectors as long as you are consistent about it at each end of any
cable.
Cheers,
Roger.

The fourth of July came a bit early for the KillaCycle crew. We
provided a $1000 fireworks display at the track yesterday. The rear
motor reverted to the fourth state of matter about 2/3's of the way
down the track.
The A123 Systems Li-Ion battery pack (376 volts) supplied an awesome
amount of HP that turned out to be a bit too much for one of the
motors. I guess I'll have to keep my comms a bit cleaner. :-)
Here is a clip of that last run for the day.
http://www.killacycle.com/Second%20Run.wmv
Here is a burn-out clip showing good use of the "bottomless pit" of
energy these cells can hold. We could have done this burn-out and the
run SIX more times before recharging.
http://www.killacycle.com/Burnout.wmv
We should have the motors all back up to snuff for our next planned
outing at the AHDRA event on Nov 10-11 at Las Vegas.
See you there,

Looking at what items I want to get done during the unpaid four day
weekend coming up, I see some EV work to be done besides fighting
the ravenous squirrels out of my garden, and looking for another
job.
The weather should be perfect to get out and do some maintenance to
my pack. I will charge my pack fully the night before, water the
cells, clean the tops of the batteries, clean up any corrosion from
acid spray, tighten the terminal connections, and reapply
anti-corrosion grease.
When I put the new pack in, I applied an aerosol can form of anti
corrosion spray. It just did not last. I am going back to the
grease form. I know it will last, and keep the acid spray corrosion
at bay.
Since it is now summer, I will need to re-check my tires air
pressure to make sure I am minimizing the amount of amp hours per
mile I am using. Since most of my pack weight is from the rear
pack, I set the front tires to 40 psi and the rear to 44 psi.
Next, I need to see where I am going to mount a DC to DC converter.
With the weather now good, I have no excuses to get this done. The
question is do I mount the DC2DC unit inside the vehicle (i.e.: in
the rear next to the rear pack), or under the hood where the
toasted Sevcon DC2DC unit is still languishing?
I have been considering getting a Kepco DC2DC
http://www.kepcopower.com/rkwp-buy.htm
ever since I saw one under the hood of Bob Schneeveis' Sparrow EV.
It is small and affordable. I figure a 15V 300 watt unit should put
out 25 amps at 12 VDC.
The Iota DLS 30 battery charger looks good too
http://store.solar-electric.com/dls-30.html
http://www.iotaengineering.com/dls30.htm
but its package design is much larger. I will have to see how much
room I have.
...
I also want to make a distance run during these holiday days off to
see the range of my now lighter capacity US125 pack (I used to have
a US145 pack).
>From Redwood City (on the SF Peninsula) going South to the San Jose
EAA Chapters meeting location at Reid Hillview Airport is about 26
miles of highway but about 33 energy miles when I include the city
street driving. That is beyond my half way point as I figure I only
have a 42 mile highway speed pack now (instead of the 50 I used to
have).
I will be dependant on the EV charging at their location. That
location's EV charging site is listed on evchargernews
http://www.evchargernews.com/regions/95148_1.htm
In reading the comment on teh above page, it looks like some AVCON
charging heads have an internal 30 amp fuse which seems odd if most
AVCONs tap into a 40 amps breaker. Perhaps someone can come up with
a fix that will allow those AVCON charging heads to provide full
power again.
But the evii.com MCS-100 with a 14-50 outlet that is also there is
connected to a 40 amp breaker, thus I will be able to take
advantage of all the power of its 240 VAC source when I use my
PFC-30 charger.
Guesstimating that I am (33 energy miles * 2.3 amp hours per
highway mile = 76), I should be ~76 amp hours down. Charging at a
36 amp rate in the begining and decreasing as the pack's surface
voltage rises, my average charge rate should be about 30 amps.
It should take (76 amp hours down / 30 amps = 2.53) about 3 hours
to fully regain the amp hours I will need to get back home. But I
may not go that route and only charge enough to make it to another
EV charging location (i.e.: Fry's in Palo Alto).
...
Well, that is great plans for the up and coming weekend, but that
isnt for a couple of days. Today I wanted to take advantage of
this good weather and do an errand during my lunch period.
I decided to give my baby the deluxe treatment and take her to
Duckys Car Wash
http://duckyscarwash.com
It is an interesting place where all the local well-to-do folks
take their new cars to have it cleaned for them.
So I pull in to get tagged and bagged for their Deluxe Package.
Then I pulled my EV forward to the first stop for the crew to
vacuum the vehicle. I left the keys in the EV so when they finish
they can drive the vehicle to the next stage.
Though I was directed to go directly to the cashier to pay, I told
the attendant I would be right back out encase the crew had trouble
(I have gone through this before. There are just too many people
trying to make driving an EV hard).
Yup, as soon as I came out of the cashiers office door, the crew
was looking at me with their fists on their hips and disbelief on
their faces as they did not know how to make the vehicle move.
English was not the crew's first language, but they knew enough to
get the job done. I had the driver sit in the EV and got him to put
the clutch in and put it in gear. I turned the key to on and told
him it was on and ready to drive. I released the parking brake, and
told him to just give it gas and go.
He closed the door, but then quickly opened the door again. He
turned the key back and forth and motioned that something was not
right. I turned the key to on, and said there is no engine.
That did not register on his face, so I reached down and used my
hand to push on his right foot on the accelerator. The motor made
the typical high speed whine sound, and then I said it is electric.
He gave an Oh and then said, ¡Eléctrico!
With a smile now on his face he slipped the clutch and slowly moved
my EV around the corner. Funny, how people want to burn the clutch
as if to not kill the motor. But it was only a short distance, so
I was not concerned about wearing the clutch plates.
After the hosing-down, pre-scrub, and run through the wash tunnel,
my EV was parked out front near the waiting area, while the crew
finsished the rest of the detailing. Normally, the clients all wait
outside in a seating area near the vehicles being detailed after
paying at the cashier. When their vehicle is done, their vehicle
model called out, you give the crew the claim ticket and tip, then
drive off and get your car dirty again.
While I was waiting I sat next to a man and mentioned the
experience. He smiled and asked the typical EV questions (how fast,
how far, how much does it cost,
). But I was able to get in my
experience in driving an ICE while my EV was repaired from the New
Years floods.
I expressed my dismay at the cost of gasoline with an Ouch!,
moving my hand away like I just placed it on a very hot surface. He
smiled and said yea with a nod. But I do not think he immediately
got the fact that since 1992 I have not had to pay for gas, and now
I am driving around gas-free. I bet it will come to him later.
I got back to work with a cleaner EV feeling, well Just Ducky.

Bill,
Godspeed on the repairs to the machine.
Was that 8.911 seconds @ 134.02 MPH on the run? Cool.

Hi Jude,
Check out L-Com at http://www.l-com.com/productfamily.aspx?id=2274 That's
where I bought a bag of 100 RJ12 (6X6) connectors and 100 feet of the flat,
six-conductor stranded RJ cable (silver satin). The link above is the whole
product family, which shows the connectors, cable and crimper (at least it
just did for me).
If you don't want to buy all that for just 12 batteries, I've probably got
enough of the connectors for you and at least 60 feet of cable left over
from the installation on Joule Injected. I've also got the
stripper/crimpers, of course. I could probably knock out 12 jumpers for you
in about 10 minutes if you give me the lengths you need. Email me at
matt(-at-)suncoast(-dot-)net if you want to do that, or if you just want
some cable and connectors. I'll be out of town until Tuesday, but I'll still
be checking my Suncoast account.
I noticed Roger's response, and I'd agree that you absolutely want to mount
them off the surface of the battery (I zorched one after placing the solder
pads squarely on a big fender washer!) I used 1/8" Lexan (or was that just
plain acrylic sheet?) and then drilled four holes each and used spacers with
little #6 screws as standoffs for each reg. Why, yes, that was a lot of work
for 25 regs!
I gotta say that little bit of protection definitely saved one reg at the
Power of DC. When the Orbital let loose at ONLY 1600 amps, it was the only
thing that stood between the spewing vents at the top of the battery and the
bottom of the reg. Just had to replace the fuse (and battery, of course) and
she was ready to go again!
Can't help you on that header. Haven't used it.

Subject: Regbus wiring and jumpers
Okay, I've searched all 24,039 unread messages in my inbox, and all the
archived messages, and I'm still a little confused.
I bought the PFC-20 and Rudman Mk2B regulators. I'm quite paranoid about
killing off my batteries, since this is my first EV. The batteries -- 12
Optima D34 YellowTops -- just arrived, so I'm working on installing
everything.
The regulators will go right on top of the batteries, and the instructions
clearly show that I can wire the regulator B- and B+ directly to each
battery. Cool.
I'm a little confused over the bus wiring. I'm going to pick up an RJ35
stripper and crimper tool, but the regbus connectors appear to have 6
conductors; I've never seen a telephone wire with more than 4. Granted, my
experience is very limited. Nonetheless, can someone advise me on what kind
of RJ35 wire I have to get, and how to lay the wires in the connectors?
As a follow-on question, what's that 7-pair header (J8, I think?) doing
there? The only docs I can find on the Manzanita Micro site appear to
describe a different version, since mine don't separate Sense jumpers.
Thanks in advance,
Judebert

Wow just $1000, that is good, we a little over $2000 powered by car
batteries when we were working on our DARPA robot
http://ssinc.us/Fire1.mpg
But seriously, even so, good job.

Subject: July 4th comes early for the KillaCycle
The fourth of July came a bit early for the KillaCycle crew. We
provided a $1000 fireworks display at the track yesterday. The rear
motor reverted to the fourth state of matter about 2/3's of the way down
the track.
The A123 Systems Li-Ion battery pack (376 volts) supplied an awesome
amount of HP that turned out to be a bit too much for one of the motors.
I guess I'll have to keep my comms a bit cleaner. :-)
Here is a clip of that last run for the day.
http://www.killacycle.com/Second%20Run.wmv
Here is a burn-out clip showing good use of the "bottomless pit" of
energy these cells can hold. We could have done this burn-out and the
run SIX more times before recharging.
http://www.killacycle.com/Burnout.wmv
We should have the motors all back up to snuff for our next planned
outing at the AHDRA event on Nov 10-11 at Las Vegas.
See you there,

Hi Michael
Welcome to the EVDL.
Just thought I'd sign up and introduce myself.
I am guessing that you received an email concerning series-wound motors,
NEDRA, the EVDL, and a certain white Datsun that makes 775 ft. lbs. of
torque @ 0 rpm :^D
You are certainly in the right place as virtually all EV component industry
folks are here as are most NEDRA racers, component builders, and other
performance EV enthusiasts.
The archives of this list can provide you with an encyclopedic amount of EV
info if you take the time to sift through.
Enjoy!

Hey Bill you better at least grab some pics for my Hall of Flame album if
those motors don't find there way here. If I could ask a favor don't discard
those old brushes. I've been talking with a brush manufacturer about analyzing
a brush (such as yours) to see what they would recommend as far as grades go.
Be a free (okay couple bucks in freight) way to get some outside input.
I have to admit that I got a lot of enjoyment from that in a sick sort of
way. I doubt I would have enjoyed it as much if they had been mine though,
lmao. Awesome video, loved the sound of the burn out as it's ending and it
chirps.
