Just like in a car, a racing engine is not really optimal for street
use and vice versa.
If you want to race, you would not want to carry the battery weight
to go 100 miles.

But you say (or else I heard from someone) that the Killacycle pack could
get the bike 30 to 40 miles, Why is that? Why wouldn't you shave it down to
just what you need for a 1/4 mile?
I know the answer is that for racing you design to the Power Density of the
cells and you have just enough cells to get you the current you want at the
voltage you want. It just turns out that with the power density you are
getting along with it, you have enough energy to go farther than you need.
I was just wondering what, in your estimation, this afore mentioned 100 mile
$20K pack would 'pack' for power? Or how much current it could provide for
say a 360V pack?

I never did ask before - is this drive in a car?
Solectria used BLDC drives in only a few cars - I think only in the first
year of Force production. From talking with them years ago, I had the
impression that many or most of those cars were later retrofitted with AC
drives. (It wasn't clear who paid for that, Solectria or the clients.
Shoulda asked.)
AFAIK, all the BLDC cars retained the stock Geo Metro transmission. The AC
cars had the Brusa/Solectria transaxle, driven by a Gates Polychain in that
early incarnation.

Because these systems are based on a capacitor [relatively] slowly
charging from 12V source
and rapidly discharging through a primary winding of the "ignition coil"
which is just a transformer with around 1:100 to 1:150 winding ratio.
Secondary then gets near 1,200V - 1,500V volts and this applied to a
spark plug which of course arcs, igniting fuel mixture.

Exactly right Bill!
Lot of people may think differently, but seeing performance of
AC systems and their cost I must say that if you're talking about such sport
where performance costs, you pretty much *always* can buy a new record
by buying more advanced hardware. If you don't know how to put it
together, buy a brains who know and you're the owner of the record.
(Don't gtake this wrong way, this is not to diminish accomplishments
of such pioneering people like Bill, Dennis or John, my hat's off,
but you must admit without money or donated hardware which cost money,
it would not be possible. Yes, people have to earn sponsorships, etc,
but this is different topic. Once they do and get money/hardware
injections, others who don't get it have no chance no matter how
bright they are. Simple reality.)
There are no NEDRA records set with AC EV not because they are worse or
less suitable to set them. It's the opposite, they are more suitable,
trust me on this. It's just so few are willing to pay for the
record yet. Today the cost of setting a DC record is still just lower,
that's all the explanation there is. Don't you think if AC motors
would cost ~$3k and DC ones - ~$10k, (assume same ratio for
electronics), NEDRA records would be set only with AC ones?
Shelling out few tens of k just for bragging rights is tough
proposition, but, again, it is not really engineering issue.

Hey Roger, thanks for helping me with that. I forgot about Uve's calculator.
This was a tough choice for me because I have almost equal amounts of cold and
really hot weather here in Maryland. The attractiveness of having a 10-15 year
battery pack that could stand up to Maryland's 15F winters was great but
watering over 100 cells, plus worrying about leaving the car unattended to
charge up in the summer heat really worried me.
The other thing I really liked about BB600's is that I can scrounge and buy
them in affordable chunks. Everyone who's selling Lithiums has a huge minimum
order. I'd need to go in on a bulk deal with someone. Plus I'm getting worried
about the rumors that the Chinese companies aren't honoring warranties on
failed cells. Dan Frederikson seems to worship all things Chinese because
they're so cheap. I say you get what you pay for.

Uve's EV calcualtor, specifcally the battery page, is your friend:
<http://www.geocities.com/CapeCanaveral/lab/8679/battery.html> Plugging your
56A and 75A specs into the Peukert calculator you can then use the resulting
Peukert exponent and capacity to compute
the expected capacity at various discharge rates. At 110A it predicts 98Ah; at
220A, 84.8Ah.
Figure on a 50% reduction in usable capacity in cold weather, so these drop to
49Ah and 42.4Ah.
Then figure on only 80% of this since you don't want to drain your lead-acid
pack completely, and you are down to 39.2Ah and 33.9Ah.

The answer appears to be yes, even in cold weather and not completely
discharging your floodies, you would expect about the same
range as the 36Ah NiCd pack.
In warmer weather, however, the lead-acid pack would drive circles around the
NiCd pack. ;^>
Cheers,
Roger.

It would probably take some special machine work to build one for a vehicle.

Hi Roy,
Can you say where you got the 500 kW figure? I assume
it was a hairball data point. Like 2000 amps at 250
volts. Who's motor?
The 200 kW is from Victor. Victor, is that output
power? Is it peak?
Thanks,

Hi Morgan,
The DC motors I see most widely used on EVs are of
"normal industrial" quality. What is the difference
of running a 4 pole DC motor 3600 RPM and higher
compared to an AC motor WRT core loss?

We just spent an exciting few weeks building a drag Bike that I thought
would take the record , No problem !!!
I guessed wrong , At one time we (thunderstruck Motors) had almost all of
the motorcycle NEDRA records.
We lost all of them when Shawn Lawless built ANGS...We want them back....Our
Bike is sponsored by Lithium Technology Corporation,
53 lbs of their Gaia batteries, two ac motors with 550 amp curtis
controllers and one 10" fat drag slick. She looks mean but is very smooth.
Well our best time time in the 1/8 mile was 8.9 sec @ 83 mph. Not bad but
not faster than ANGS at 8.66 @ 78 mph.....The thing about it is that
we were just to slow off the line, maybe these ac motors just do not have
the torque required to compete against series and PM motors????
We have decided to try a few things before we give up here,1) we are 2 cells
short of our voltage limit, so we will add 2 more P strings, so we do not
have a voltage
disadvantage.2) we will gear a little lower, it was geared to go about 100,
3) we will connect the second motor.

The free website doesn't make them look very promising. The website

Maybe they are another manifestation of LionEV?

Come to think of it, it has been hearing John Wayland repeat this figure in
video after video that I have been seeing for quite a long time now. So I guess
the "motor" would be the siamese 8, though a motor (or motors) is just a
conduit for what is available from the battery pack managed by the controller.
IIRC, it is mentioned in one of the recent videos from Film Ranch and the
report done by David Brill for SBS TV Australia for example.

He said he can supply a 100ah @ 44.8 volts pack with BMS for about $4300.00.
That comes with a 3 year warranty.
It takes about 90 days to complete & be shipped here.
He said he stocks the 200ah @ 44.8 volts packs with BMS for $7300.00.
He also said I can pay for my order via credit card.
Which I feel offers a little protection. "

Hi Rod an' EVerybody;
You Newbees? Didya check THIS one out?You don't hafta have deep pockets
to play here!48, 60 volts and a light car, home made contacter controller.
Get's ya in the club! Driving my 87 Sentra, with a Curtis controller, 90
volts worth of batteries, It goes 60 MPH, in awile, but I run along in
traffic at 40-50 MPH, hasn't used a drop of gas in over 100 miles! Still
tweeking it; like a HEATER, DC to dc, charger. Charge with a veriac
rectifyer setup for now. Not as quick as a 120 volt Jetta, but good enough
to haul Groceries, as I did last nite.
So go out and find a Rabbit, or Geo, something small an' LITE, and have at
it! We're here to help!
Seeya
Bob with TWO EV's in my garages! One for each foot!

that may not be true however. think of the weight percentage the pack is
in your bike compared to a 250kg pack in a car

Victor, are you hinting that there are some 2000 amp 360 volt AC controllers
out there small enough to go in a car. I have always wished for a high
performance AC drive. This is the pancake brushless DC motor I like but the
drive is bigger than a refrigerator. It runs on 700 volt DC and is lighter
than a small block Chevy. It produces 1475 ft/lbs of torque from 0 to 100
RPMs. It is only rated at 450 hp (336 KW) but I believe this is continuous.
It is only 8.8" long and 25.5" diameter. You could put two of these end to
end under the hood. I believe this would be the hot set up for a quick car
if someone would build a double breadbox sized 1.4 megawatt AC controller.
Victor, please let me know when you have these controllers available :-)

No, but there's a 360 amp 900V AC controller designed for EVs out there
(google evisol).
That said, that's still only half the power of a Zilla, and it won't get to
full power until fairly high RPMs, unlike a series DC setup. That said,
higher efficiency means more running time before overheating; you're a lot
less likely to get a Zombie or Killacycle style plasma ball.
I don't think AC will win in drag races anytime soon, but AC is probably
much more competitive in most other types or racing, from autocross to
distance racing.
