If you had a Subaru WRX, would you take it up to ~6,000 rpm and dump
the clutch to get the best 60 ft time?

Subject: What an EV filled day!
(Stuff snipped out)
On the way back we drove over to another Phoenix EAA members house where
a 1955 VW Chassis Jeep kit car conversion was being kept
http://www.phoenixeaa.com/classifieds/sold/060101/main.html. I got to
drive it and this things really a fun little car. The body's all
fiberglass so it's really light weight. It's only a 120 volt system
running on 12 volt Trojan's, but it is very spirited and lots of fun for
sure.
That Jeep looks like something I'd like to have had. I spent considerable
time during the
1990s plotting and planning to make a car like that. It would be great fun
to drive during
weather that permitted an open body. It's not big enough to carry much more
than a
120-volt pack of 12-volt batteries. Its lack of streamlining would also
limit it to short
trips at moderate speeds.

I'll be attending this conference from Feb 15-16. If
you plan on attending send me an email and we can meet
up for lunch. We
can compare notes on how these drives apply to EV's.

Greetings,
First I will start off by saying that I have no association with
STMicroelectronics or even free samples. But, I will say this. From my
usage of their ISOTOP components in my DC motor controller designs, I
have found them to offer the best of many worlds. They also offer many
flavors of components in this package: diodes, MOSFETs, IGBTs,
Darlingtons, and a couple of others.
Unless there is something I am missing, I see a new generation of
extremely low-cost high power motor controllers.
For example, our senior design project uses STE250NS10 MOSFETs. These
MOSFETS are rated 110A @ 200V. Now, I do have good knowledge of what the
data sheet says vs. real world thermal analysis, but even at 1/2 this
rating continuous it is a good deal. So why did we choose these
components...
High power capable, high speed, robust bolt down package, PSpice models
available, and LOW COST for bolt down types.
Not knowing at the component selection time what we know now, we would
have actually gone with the MOSFETs that were 220A @ 100V. The reason
for this is that our controller is for a PM DC motor and has regenerative
braking. Well there really aren't common PM DC motors that operate at
our original 144V rating. In the future we will be a 72V higher current
system. 144V means 2 motors in series mabey, but that just adds cost.
Our diodes are also in the ISOTOP package containing 2 120A diodes.
I look forward to discussion on this subject, especially points with good
backing that prove me wrong.
VR,
STEVEN ARLINT

Hey guys,
I'm sure Dennis will have something to add to this, but while finishing
up a story on the CE and Dennis, he sent a final email stating that,
"Also that CE will be on the auction block at the next BARRET Jackson
auction to raise funds to build a new advanced et dragster that will
accept that new motor."
Finally, "Also you can post that ce will pay the 1st electric to run
quicker than its record $1000"

As an engineer, I love the Isotop package. Isolated mounting, screw
terminal connections, lower thermal resistance, and higher current,
voltage, and power ratings than you can get in "normal" packages like
TO-220 or TO-247. It's used by IR, IXYS, Motorola, and others as well as
STM.
But, the bean counters usually force me away from it due to cost. The
Isotop costs more than several TO-220 or TO-247 parts in parallel. Sure,
*I* know that the Isotop will save money on mounting and matching, will
be more reliable, easier to service, etc. But it's hard to prove these
advantages to a bean counter. They look at the price and say, "$10 a
pop? Are you out of your mind!?! We're buying TO-220s for $1 each."

Unfortunately Greg's Scirocco is not online anywhere that I'm aware of. He
bought the car converted already 2 years back and has been keeping it running.
The car has a GE motor and G.E. EV1 controller (the humming SCR based one). The
pack consists of 20 T-125's, and he says his range even with 2 year old
batteries is 40 miles. He does drive it for efficiency though. When it had new
batteries he was driving it something like 70 miles a day. He said it could
have done 100 on a charge. I don't know how far that would be pushing it, but
on the little ride I got the amp draw going down the freeway was looking like
something to the effect of around 50 amps.
I'll ask him some more specifics next time I see him, but he's made every
attempt necessary to make it more efficient. The car even has some EV1 Michelin
Proxima RR tires on it!

Ricky, where can I find more information on this electric
Sciroco? I found nothing on the Phoenix Area Electric Auto
Association site, and I'm curious to see just what setup is
being used and how much range this car would have on new
batteries. From the 130 mile trip that implies the car will
go at least 65 miles to 100%, but that could kill the pack
and if that trip is to be made I'd guess on it having more
range. What sort of efficiency is it achieving?
Acceleration? Speed? Any pictures?

Yes, it was really fun to drive. Given how open it is I would probably avoid
the freeway with it, though it felt like it would easily do freeway speeds. It
would be a blast to just tool around the city in. I might replace some of the
PVC roof supports with some steel tubing for a bit of roll over protection.

Also very impressive is that the back is electrically insulated, right?
That simplifies mounting enormously, and you don't have to add the
thermal resistance of the insulator so you get a very low
junction-to-heatsink total.

It's more than $10 from what I saw. Digikey was $35 in singles, $25 in
quantities. I thought they were much more expensive than that, maybe
they've come down since I remembered.
Yeah not only are 10 transistors basically 10x more likely to fail than
one, but one would generally suspect that a single cheap transistor run
at 50% capacity to be more likely to fail than an apparently very well
made one running at 50% capacity.
I did note that the datasheet mentions the current capacity may be
limited by the attachments, and that may be a concern. The screws are
4.2mm, 12.7mm apart, on an 8mm wide unsoldered conductive surface. It
would take a pretty funky lug to join a big conductor like even 4ga wire
onto that so this would be something to work out. 10 devices feeding a
busbar don't put as much current through one point.

With an EV's awesome low end torque, it would not be necessary to rev
it up like that.
If the driveline would survive, the highest rev you can start with
without wheelspin would be fastest. I'd check the online boards
before I did that to a WRX, though, and make sure it would survive
the experience -- some AWD's don't have a good reputation that way.

That is definately one thing against my point. Bean counters.
An example of what you said for ISOTOP vs. TO-247:
The STW40N2 is a STMicroelectronics TO-247 case MOSFET (200V 40A). 3 of
these guys equal 1 STE110NS20ND (200V 110A ISOTOP) just about right on.
The balance is very close. The tangibles that bean counters look for are
the same. Heat dissipation, Gate-source capacitiance, internal
resistance, volume, etc. With the exception of price. 3 TO-247 parts
are $7.72 on digikey vs. $35.00 for the ISOTOP. I don't know how this
scales for massive quantities, but the concept is there.
So in order to better justify the ISOTOP I guess that there needs to be
some benefits identified in the realtively more intangible categories.
Longevity, ease of mounting and servicing, easier to integrate into
design, less points of failure, electrically isolated base. Most of
these were already outlined in previous e-mails.
This makes it difficult for new people in the motor controller business
like myself. Companies like Curtis and others use the less expensive
packages in their products. They know how to design around these
packages and have done so for years. So what do I do. Instead of using
a bunch of small MOSFETs where layout is critical, I use a couple of BIG
MOSFETs. I believe Lee Hart outlined this technique couple of weeks
ago. It will be very hard to be price competitive if I do this.
However, I am not really centered around money. If I don't make it rich
in life, but I get to bring many great succesful products to the market
for people to use, that will be good enough.

100 miles range on new batteries!? 50 amps to cruise freeway
speeds?
Holy shit! He needs to get that thing on the
www.austinev.org EV Album soon. A lot of people could learn
from this car if that info is correct.
I imagine that to get a 50 amp draw in such a car would
require extensive efficiency improvements. I want to know
what he did to achieve this so I can figure out the accuracy
of the claim. I do believe it's plausable, but again, it
would require a lot of drag reductions! and I'd guess this
is at 50 mph speeds as well, as 6,000 watts(50A*120V) to
cruise isn't much.
But hey, high school kids have built 140 mile range EVs
using flooded lead acid. Notable is "Solar Bolt", a
converted Fiat X1/9 that used 20 Trojan T145s, weighed about
3,000 pounds, 1,400 or so in batteries, extensive aero mods
for .30 drag coefficient, machined brakes to cut brake drag,
0 camber alignment, synthetic tranny oil, ect. I'd love to
duplicate that with AGMs some day in a smaller car.
If what he says is true, I'd like to apply his techniques to
my much smaller and even more aerodynamic Triumph GT6
conversion in progress. The only way I will ever be able to
get range *and* performance in the same car is through
efficiency, and if what you were told is true, I could learn
a lot from this guy. If I get my drag coefficient down to
~.25 through aero mods and use LRR tires with about a .008
cr, I might be able to achieve 150 wh/mile at 65 mph
according to simulation. .006 cr gets it down to about 130
wh/mile at that speed. This efficiency is what would allow a
range in excess of 100 miles on about 1,100 pounds of AGMs,
and the performance to go with it for those days when I
don't care about range.
Get him on the list as soon as you can!
Would it be possible for you to email me his contact info? I
have a lot of questions, first and foremost, where in the
hell did he get those EV1 tires?
Anything that could maximize my efficiency, I'm all ears.

this tires are terrific, just switching to them i have seen near 20% range

Hey all,
I rec'd the following send yesterday.
a) I don't have a "company". I have a cool car that
I'd love to stuff with LiIons.
b) I don't speak Chinese. Thus I can't get any specs
for their batts.
c) I don't generally do business with totalitarian
regimes, even if they do provide health care for their
citizens. And I don't generally do business where
laws are in the development stage.
That said, has anyone else gotten the same letter? It
says, "BlueSky." Is this related to the Thundersky
discussion list I'm on?
Thanks,

I'm putting together the same configuration for my car. I bought a couple of
plates made of
phenolic resin, supposedly sheets of paper impregenated with the resin. It's
suppposed to machine
easily, drill and tap well and handle temps over 200C. Each plate is about a
half an inch thick
and I'll be layering them into a block about 2 inches by 6 inches by 15 inches.
This will slide
right back into the location that the heater core came out of. I hope to
sandwich the heater cores
into the middle layer of this block.
First, has anyone tried using an automotive gasket sealer to bond these cores
to the frame?
Something like UltraCopper, etc. I've seen some products that claim to handle
fairly high engine
temps and I would think they'ed work. How hot does the ceramic heater core
actually get? Is there
another product that would glue these cores together, handle the heat, yet
remain somewhat
flexible?
I noticed one photo showed three cores side by side, the same way I plan on
building mine. I know
this has been covered before, but can someone provide a schematic on how to
wire these together
for two heat ranges? I plan on a high voltage pack, so three 120 volt cores
wired in series would
be perfect. Also, these cores allow for two heat ranges, how do I wire for that?
Thanks

i received it too, their li-ion spec. look like UPS batteries not enough
power, too much voltage sag.

Et si le pot d'échappement sortait au centre du volant ?
quel carburant choisiriez-vous ?

Hello to All,
Its' all Otmar's fault.....
Now that he's an Oregonian and is within a 2 hour's drive of Portland,
we get to see each other more often than when he was one of those
Californians. On his last visit to the Wayland laboratory, as usual,
time was spent in his outrageous s-t-r-e-t-c-h VW bus with the tunes
cranked through the Wayland sound system. After abusing me with some
limp, bass-less acoustic earth muffin crap, Oat finally put on some
downright funky stuff. I was immediately drawn to it (he knew I would
be) with its low 5 string electric bass, killer drum mix, gurgl'n
Hammond B3, and the requisite Fender strat clik'n 9th cord grooves :-)
Even though it was sourced off Oat's iPod and formatted in dismal lo-fi
MP3, I could still imagine how it might sound with full fidelity. Yup,
in an instant, I was hooked on Jon Cleary and the absolute monster
gentlemen...had to have that CD!
About a week later I decided to seek out this hard-to-find recording,
and after Internet searching and a confirmation phone call, I was happy
to find that one of Portland's many hippie type record places, Music
Millennium on Burnside, had exactly one copy of it. The off-the-wall
record shop is about 5 miles from my place, so I decided to drive Blue
Meanie for the early nighttime music run.
As I've written lately, the aged pack of Optima Yellow Tops are pretty
tired after now, 6 years of service, so the car's normal 25 mile range
is down to about 10-12 miles. Yeah, I know, I've got no real excuse
here. My EV shop is lined with new Exide Orbitals. Let it suffice to say
that swapping out the 13 YTs and installing 17 Orbitals (different
footprint and profile) in an all new configuration isn't a simple job.
When you consider the car's unique rear motorized battery tray that
would need to be reworked, the new quad 8 subwoofer enclosure volume it
has to clear, and all the other physical restraints of a small 70's
econo-car, it's really pretty reasonable to think of how I might keep
putting off the project. I'm also not 100% ready to use Orbitals,
either, as I've grown awfully fond of the Hawker AeroBatteries that
reside in White Zombie! A high voltage pack of the feisty orange
batteries would sure look cool against the car's violet pearl over royal
blue paint, and 100 lbs. more of lead would possibly bump the car's
range to around 30 miles per charge...336V @ 1000 amps would be fun,
too! I digress....
The PFC20 hotrod charger had just topped off pack, but the cycled to
death Optimas were only sitting at 157V static for about 12.1V per
battery :-( In their younger years the YTs (156V nominal) would pretty
much hang in the 167-169V range, but 6 years later, 157V is all they've
got left. The temperature was on the cool side at around 45 digrees, not
lead acid range-friendly conditions, but I did check the LRR tires and
found them sitting at 50 psi. With the pack just off the charger I
headed out to get that CD.
As I pulled onto Glisan Street and mildly accelerated, the pack that
used to stay stiff at 1000 amps of current, now fell to the 135V range
with maybe a 400 amp draw...hmmm, better drive conservatively this
time....better behave myself. I settled into a 40 mph cruise but had my
eye on the Emeter reporting just 151V under a very light 45 amp draw.
Still, even with a restricted amount of battery power, this car is soooo
fun to drive! I was enjoying the ride as I glided along in my trusty EV
friend, now 26 years as an EV to this month, February, since back in
1980 when it first ran on battery propulsion. Even with 6 year old
batteries, it still had ample power, but with a 10 mile run ahead of me
this was going to be a tepid cruise.
Glisan is pretty level for the first mile and a half heading west from
my house, then it dives down a steep hill before leveling out at a lower
area just as you approach the busy high traffic four lane north-south
82nd Ave. that Glisan intersects. I had nursed the car slowly up to
speed, closer to 48 mph... a bit above the 40 mph speed limit but
certainly not what any reasonable person would consider speeding. The
idea was to crest over the top of the hill at a pretty good clip, then
go off-throttle down the hill with the clutch pushed in for the ultimate
in low rolling resistance, to milk as many miles range as possible for
this little trip to the CD store...the things an EV addict does to run
on electricity! I was concerned about the pack to the point where I was
actually planning my strategy ahead, thinking of how I would handle the
light at 82nd, & Glisan, should I have the misfortune of having it
change at the last moment to red. Would I give up on seeing yellow, hit
the brakes and stop for the light? Doing so would throw out all the
advantage the hill gave me, and, cause me to use more precious current
for another take-off from stop. Would I see yellow and stomp the
accelerator to make the light? Doing so would also throw some of the
advantage the hill gave me with the extra high current draw such a stunt
would suck up, and, it would have me driving on the stupid side of the
law, too. Believe it or not, I actually had this little discussion in my
head as I crested over Glisan hill.
OK.....as I get a small roller coaster effect lofting over the hill, I
see the light down below at 82nd is green....not really a good thing,
because it's about a half mile down the hill to reach the light. Will it
stay green and allow me to go on my way? Will it instead, turn to
yellow-then-red and halt my progress, robbing me of the momentum? So
here I am, coasting down the hill at maybe 50 mph, right in that
speeding ticket range. I make it within maybe 200 feet of the
intersection when the damn light goes yellow! In that brief brain dump
of mine, I again weigh the options....stop and loose all the
momentum....nail it, suck big amps and fly through the intersection and
still be on the losing side of the power equation, and, risk getting a
ticket if there happens to be a cop in the area (and also be a hazard
for others).......man, what should I do?
I went for it, and while letting out the clutch in 4th, slammed down the
pedal! To my surprise, the old Optimas still had some punch left, and as
the Zilla pulled as many amps as the batteries allowed, Blue Meanie
rushed up to probably 65 mph or so....OK, maybe as high as 70! As the
car and I fly over 82nd the light's still yellow, but probably turning
to red as the Meanie's rear bumper clears the far west lane of 82nd. It
was kind of a rush, being bad and all, but I had made it, no one got
hurt, and Blue Meanie was really zinging along now. Before I coast down
gently to the speed limit while covering the next mile or so on zero
amps, I decide I had better scan the rear view mirror, just in case
their might have been a cop in the area.....D'OUGH!!!!! To my horror, I
see a Portland Police cruiser pointed south on 82nd, yeah, right at the
intersection I just flew through! There's two cops inside, and they're
in the inner lane. I see their heads twist in synchronization as they
follow the path of my car.....damn! As I'm watching in the mirror, I see
them jump ahead into the intersection as they do a tire-smoking 90
degree cookie, cutting right across the lane to their right (how they
kept from being T-boned by the car next to them ready to go through the
green light, I don't know)...they don't have their lights on yet, but
it's obvious, they're in hot pursuit of 'me'! Damn! I now have this sick
feeling as my genitals are receding into my lower abdomen, and I know
I'm busted! What do I do now, to minimize the damage? If I stand on the
brakes, in the fading light of the day the bright red brake lights will
signal I'm having to use the binders to hunker down from speed....that's
an admission I don't like at the moment. I decide against that and
instead shift down to 3rd....damn, it's an electric...no compression to
slow me down! Where's that regen when I need it? So here I am, still
flying at 60 mph or so in a 40 mpg zone, with cops coming up on me in
full pursuit at maybe 75 mph. Damn! I'm gonna have to hit the brakes,
and as I do, my world's now suddenly lit up with the brightest LED blue
and red flashers known to man!
OK, I've accepted it, I'm busted, time to give up....right turn signal
on, and I take the next available street off Glisan into a neighborhood
I'm instantly familiar with. It's coincidentally, the late Dick Finley's
old area where he once lived, and where he too, often terrorized other
motorists with tire smoking antics in his rocket Renault EV. 82nd used
to be his hunting ground where he'd egg-on muscle cars at stop lights.
He loved being the 'old man' in the funky Renault that would roast both
front tires for 100 feet in 3rd from rest. In that brief moment of panic
as the cops have collared me, I can feel Dick smiling down on me and
saying, "I never got caught, you moron!"
Next frame....I'm pulled over, have gotten my license out and realize my
driver's window isn't able to roll down with the electric lift switches
disconnected (been working on the new stereo lately and have some things
not quite finished). Cops don't like it when a suspect suddenly opens
the door as they approach....I sure hope they don't Taser me, though the
old Optimas would probably like it.
I also realize that the glove box is temporarily out of the car, thus,
my registration and proof of insurance aren't with the
car.....D'OUGH!!!!! Icing on the cake....I've got expired tags, too!
Geez, I'm toasted here....I'm going downtown, for sure. I now have
visions of my wife with steam coming out both ears. It's definitely not
my finest hour, I've been bad, and I'm going to have to pull off a
miracle to get out of this one. Time to summon up all that Greek BS I'm
full of and put it to use.
So the male cop is near my door now, and his female partner is on my
right with her requisite 2 foot long flashlight. He's a big strapping
young guy, probably 27-28 years old and to my surprise, doesn't look all
that upset....she's pissed though, is scanning the inside of the car,
and looks as mean as a rabid dog! It's about 6:30 pm, so it's more night
than day as the cop car's lights are pulsing the once peaceful
neighborhood, their extreme intensity red and blue LED flasher banks
combining to flood the area in a purple aura. There's folks walking
their dogs on either side of the road, curious to see what degenerate
has been apprehended, and there's a couple looking out their front door.
Unbelievably, I ponder in my defective brain the scene that's unfolding
and say to myself, "this would be such a great photo opt!"
Back to reality....I need to 'carefully' open my driver door, and as I
do so, I s-l-o-w-l-y hand out my driver's license as I'm recalling
recent police officer shootings of traffic stop victims they interpreted
as being hostile and having put them in life threatening danger. One
stupid move on my part, and this could be the end of Plasma Boy! As the
license is extended out the cracked-open door I say, "My window doesn't
roll down...sorry." I notice the officer's hand is already over his
weapon, but he seems to understand I'm just a goofy guy in his little
old econo-car going too fast. I ask if I can get out of the car, and
with his partner ready to assist if something goes wrong, I'm allowed to
emerge from Blue Meanie....whew...no bullets, no Taser.
Male cop........"You know why I pulled you over?"
Plasma Boy...."Well, I can think of three reasons." (I've decided
honesty's going to be the best policy here, he seems to be reasonable)
Male cop (now grinning and chucking a bit)........"Three? This is going
to be good...let's hear 'em."
Plasma Boy...."One....not that I'm admitting anything of course,
but.....I was 'possibly' speeding?"
Male cop (with a bigger grin and still chucking)........"Yeah, that'd be
one one of them."
Plasma Boy...."Two....that.....'pink' light back there?"
Male cop........"I'd say red. I've gotta know...what's the third one?"
Plasma Boy (ready to make his play for forgiveness)...."Oh yeah,
three.....you figured out this was an electric car, you think it's cool,
and you want to check it out, so that's the
real reason you pulled me over."
Male cop........"An electric car? Really? That explains your 'VOLTS'
plate. Geez, the thing sure accelerates! I saw you pick up speed in
a hurry as I watched you blow that light.
Female cop (still not amused one bit)........"I'd say so! You put on
quite a demonstration for us. Are you an idiot? You didn't see us
right there?"
Plasma Boy (addressing the rabid dog)....."I'm really sorry, officer,
that was stupid and I apologize....wanna see my motorized battery
tray?"
And with that, it was show and tell time. The officers were way cool,
especially considering how guilty I was. The neighbors walking their
dogs came in for a look, too. We chatted about all things EV, and about
my other electric Datsun, and I of course, I told them about electric
drag racing while emphasizing that we did our serious runs only at the
track. And then, I remembered the idea Tim and I have been kicking
around about getting a police officer to allow us to do burn-outs with
their cop car's lights on and all. The officer at hand was very
interested and said he was sure that we could work something out, so
long as I gave him a ride! I told him we'd get back to him in a few days
to see what we could work out for a fun photo shoot. After a good ten
minutes or so, he told me he still had to check my record out, and asked
me to hang by my car...which I did. While the officers were in their
patrol car together, I purposefully stood in front of the rear plate to
hide my expired tags!
After a fashion, the officers reappeared to hand me back my license
stating, "Mr. Wayland, you have a perfect driving record. I see no
reason to ruin that for you tonight.....cool car! Oh, and we know about
the expired tags, so you can move away from the plate now...go get those
tomorrow!"And with that, they turned off their lights and drove away.
Man, talk about dodging a bullet!
Getting back in my car, I was still trying to come down from the rush of
it all. The Emeter told me that the pack was still doing OK, so I got
turned around and headed down to the record store to pick up the
CD....and yes, I dutifully cruised at 40 mph all the way. The rest of
the story isn't anything exciting, as Blue Meanie made it back home even
though its pack was sagging pretty bad. I put it on charge right away.
The batteries seemed to like the heavy discharge and took a deep drink
from the charger. When finished off and left to rest for about a half
hour, the pack was reading 162V static. Those Optimas just keep bouncing
back.
See Ya....John 'but officer I couldn't have been speeding, it's an
electric car' Wayland
Note: Blue Meanie has a fresh set of tags now, good to Feb. '07
