So far as I have found the two that I know of so far
that are easy to use as an electric conversion is the
BMW. It uses a dry clutch much like a car. And the
Harley Davidson. It has a separate transmission with
the clutch attached and can be driven by a belt. This
it probably the simplest to use and is beefy enough
for any motor you can put on it. Let me know if
anybody knows of other bikes that have tranny's that
would work.

Thanks for the details. It may have had two sets of windings (one for
each speed), or used "consequent poles" in which you reverse the phase
of half of the existing windings, and have a second set of poles with no
windings on them. These are two very common methods to get different
speeds from an AC motor running on a fixed frequency.

No; consequent pole motors use all the windings all the time.

The AC motor is cheaper than a DC motor if both are manufactured in the
same volumes. But AC inverter-grade traction motors are built in *lower*
volumes than DC motors -- thus the AC motors used in the auto company
EVs are more expensive than DC traction motors.
But as Rod Hower pointed out, there are getting to be some high volume
applications for AC traction motors (like fork lifts). That is going to
shift the balance in favor of AC.

Yes, but as software engineers like to point out, it's only a "little"
more complicated. And computer hardware and software is "free".

Yes. Note that almost all really large AC motors have slip rings. We can
deal with 1 KW of loss in the rotor of a car-sized AC motor, but it
becomes 10's of KW in a motor large enough for a train or other large
equipment. They *have* to use slip rings to get that power out of the
motor, or it would burn up! Plus, there are lots of things you can do
with slip power.

Tricks like series/parallel switching are the things you do to squeeze a
little more performance out of a design. The auto company EVs didn't do
it, because they are new at the game, and don't know any better, and
don't (yet) need to squeeze more out of them. But all the big, long-time
AC traction motor drives use these tricks. Their designers have already
had decades to think about it, experiment, and work out the details.

A man after my own heart! I don't have to go too far, but I've got to

I'm glad you haven't given up on it.
I was looking at a Rabbit on the EVDL photo archive; he had batteries

weren't so deep, leaving more room for the batteries.

This brings back good memories.
Ryan and Harold stopping by the house in NC back in
1995? to get better EV controls from GE (I worked for
GE from 1993-1996).
These guys have been promoting the EV cause via the
most important audience, the future engineers from
high schools.
Ryan, Harold and Lee Hart have the right idea, teach
them young about the benifits of alternate energy
vehicles. These are the future engineers that will
make this possible.
I've seen many students persue jobs in the
EV/alternative fuel industry because of their efforts.
Thanks to these EV pioneers in inspiring the next
generation.

We have a full size conversion van, I bought it back
in 1994 because my family gave me a huge discount :-)
It sits in the driveway 90% of the time because we use
the electric TEVan for most around town commuting.
The TEVan battery pack hangs kind of low, I avoid
all road kill for this reason, I don't need dead
animals on the pack (and it has happened several
times, thinking I had the road clearance of the other
cars that avoided this obstruction).

Physically, the inverter for a 2-phase motor is the same as for a
3-phase motor. However, one of the phase leads is the common, and the
other two are the two phase voltges, with a 90 degree phase difference
between them.
If you blindly connect a 2-phase motor to a 3-phase source, it works but
at lower efficiency. Likewise, you can run a 3-phase motor from a
2-phase source at lower efficiency.

In China our fixed overhead has been substantially reduced and we run
our production
line only when there is appropriate demand.
Didn't we already have reports that the line in China had been
completely shut down and that these batteries were officially
unavailable from this point forward?
Our largest customer, Oxygen SpA, remains committed to our products
and is projecting substantial orders over the next several months.
Does this mean that Oxygen is projecting orders for Evercel, or does
this just mean that Oxygen has projected substantial scooter orders and
Evercel is trying to spin that into possible orders for Evercel
battteries? I think this might be intentionally vague. Does Evercel's
delisting mean that they are now free to mislead their shareholders
without legal consequence? This is not a charge, just a question. I am
unfamiliar with SEC rules and corporate law. Didn't Oxygen state that
they have another supplier for NiZn cells with 20 or 30% better
performance? Didn't Oxygen also state that they didn't expect to be
getting any more product from Evercel?
We intend to supply batteries for these orders if economically
appropriate.
This statement sure sounds sounds fishy. Either you have the orders or
you don't. Either you have the ability to fill these orders or you
don't. Either the line in China is operational or it isn't. All this
conditional language from Evercel sure looks like nothing but double
talk and tap dancing to try to soften the blow to their shareholders.
I wish any advanced battery technology company success, but if the party
is over, shouldn't they abandon any pretext of future production and
focus on their entirely new and totally unrelated Zipcar investment?
Is there anyone inside Evercel, Oxygen, or their partners with any more
information on the assertions made in this letter to investors?

This was an OT question since my hot tub on the
deck uses a 230Vac single phase motor and keeps
tripping the GFI.
I have a 120VAC input, 230Vac 3 phase AC inverter
in the garage that runs my grinder. I was considering
running 2 phases to the hot tub pump from this
inverter just to see if it still worked.
Another OT,
I always wondered if this inverter could produce
120Vac single phase from two outputs if I programmed
it for 60Hz 120Vac 3 phase output?

The motor would turn fine is my quess.
and I can't see the inverter minding if there is no load on one leg,
unless it is using that leg to measure bemf or current in the motor
windings.
The problem I see is that, motors starting under load are 3 phase, call
them capacitor start or starter windings they are there to get the thing
rotating from a stop. 2 phase sets up a magnetic field that appears to
oscilate to the stationary rotor. 3 phase set up a field that appears
to rotate.

It could; but it may also be that the inverter designers "protected" you
from such things, and wrote the software so it will shut down if it
loses one phase, or if the load current isn't balanced in all 3 phases.

No; a 2-phase motor also creates a smoothly rotating fixed-amplitude
field.

Early on I was skeptical of Kettlewell's "Electric Dreams" because of
the marketing language, but the book really is good. I think it will
sway most "normal" readers into becoming "ampheads" like us.
The author draws readers into the story through humor and wit, along the
way educating the reader with EV info. This isn't the book for you if
you love purely technical discussions, but if you want to see electric
vehicle technology from a new perspective in an interesting scenario--
and you like to root for the underdogs-- you might want to add this to
your collection.
If anyone is curious and would like to obtain a copy, I have a few left
in stock...

Posted on Sun, Apr. 18, 2004 Rural N.C. kids take electric car
prize BARBARA BAMBERGER SCOTT Special to the Observer ELECTRIC
DREAMS By Caroline Kettlewell. Carroll and Graf. 290 pages. $24
High school kids from rural eastern North Carolina, cars,
competition, and the Richmond International Raceway -- a surefire
mix for a winner of a book with an (almost) guaranteed happy ending.
Caroline Kettlewell got a grip on this story while it was still hot,
and keeps us holding our breath until the checkered flag on the
last, strangely quiet, lap.
Strangely quiet because the cars were electric, and the challenge
for these high school kids and their dynamic duo of instructors was
to build an EV (electric vehicle) that would pack enough juice to
beat out the competitors -- not only on the track, but in the arena
of design, efficiency, and oral presentation.
Our N.C. kids (from Northampton County) dubbed their car "The
Shocker." And shock it did.
It shocked the competition, who reckoned Northampton High
School-East was all about "hay bales and tractors." It shocked the
teen team, who had signed on in good but often wavering faith, not
at all sure that kids like themselves, from a rural backwater, could
win anything.
And, though they might not admit it, it was a shock to Eric Ryan,
the transplanted Californian who'd come to Northampton County as
part of the Teach for America program, and his unlikely
comrade-in-arms, Harold Miller, a good ol' boy auto mechanics
teacher with attitude.
With fewer resources and a smaller reservoir of hope than the kids
from other schools, the team at Northampton-East had the benefit of
hands-on instruction and rare teaching zeal, plus a dash of NASCAR.
They knew what racing was about, though sometimes it was hard to
convince them that The Shocker was ever going anywhere.
Kettlewell never leaves us out of the action: "If you were a student
electric vehicle team working in the shop at Northampton High
School-East and you wanted to establish the starting weight of your
1985 twice-totaled Ford Escort Hatchback before taking the car
apart, you could take it just down the road about a half-mile from
the school to the peanut scales."
When Katrina, a college-prep student who joined the team to fill a
hole in her schedule, wins the range test by driving The Shocker for
a full 90 minutes around the D-shaped Richmond track minus her water
bottle and nearly delirious from dehydration, we're with her every
lap.
Everyone who got behind The Shocker's wheel was surprised to find
that it was scarcely audible and incredibly fast. You have to stop
thinking "golf cart," Ryan and Miller kept emphasizing. Surfer Ryan
overcame his mellow streak in his determination to get his team of
raw kids to the final showdown. Miller showed hidden depths of savvy
and suave that got him into conversations with the people behind the
scenes who had the scoop.
One early piece of advice Miller gleaned was to have the car ready a
month early so there'd be plenty of time to work out the glitches.
And there would be, someone else told him sagely, plenty of
glitches.
The Northampton-East EV team has become NEAT (Northampton Electric
Auto Team) with a Web site listing their many victories. Ryan stayed
on in rural North Carolina long after his Teach for America contract
expired, and is still involved in EV development. Miller, who always
thought there had to be something more efficient than the
gas-guzzling internal combustion engine, stayed involved in the EV
Challenge after retirement, offering help for schools willing to
develop and test alternative vehicles.
They're still wondering "why a bunch of high-school kids can manage
what the big car companies insist can't be done."
MEET THE AUTHOR Caroline Kettlewell will sign copies of "Electric
Dreams" at 2 p.m., Saturday, at Borders - Morrocroft, 3900 Colony
Road. Scott is a writer in Dobson.

I'm glad you haven't given up on it.
No, I've had a good pout and cry, and will be replacing the pack.
The more I look at my telemetry logs the more I am sure that going to
the IUI charge algorythm blew the pack. It's ok; this was a learning
experience. But trying to run at pack at an average of 15 vpb at 10 amp
charge rate is simple suicide. Even with regulators, it's suicide.
I'm going to reprogram the MC to go back to it's factory setting. I have
it somewhere, but I think it was CV to 350 volts, then CC to 375 volts
with a charge limit current of 1 amp or so. That way the pack can bulk
up quickly, but when the pack hits 14 vpb (and some are at 15) the
current is dropped way way back.
The batteries are bulged as well. It was not undercharged....

Converting the Dodge Caravan would be an option, except for the fact
that it is the *least* reliable car we have. And that includes a 68
Porche 911L and a 74 914.
Oddly enough the motor and transmission are the only reliable parts. :-)

It sits in the driveway 90% of the time because we use
the electric TEVan for most around town commuting.
The TEVan battery pack hangs kind of low, I avoid
all road kill for this reason, I don't need dead
animals on the pack (and it has happened several
times, thinking I had the road clearance of the other
cars that avoided this obstruction).

A man after my own heart! I don't have to go too
far, but I've got to
take the kids. If my Prizm hatchback wasn't
leaking, it would be my
first choice for a conversion.
I'm glad you haven't given up on it.
I was looking at a Rabbit on the EVDL photo archive;
he had batteries
under the rear seat, but he had customized the seat
cushions so they
weren't so deep, leaving more room for the
batteries.

It's such a new vehicle that I don't think anyone has tried to convert
one yet. So, it will be a bit of an adventure! Most of the work will be
routine, and just like any other EV conversion. But there are bound to
be some new tricks that will have to be figured out and worked around.
I looked up some specs on the Murano on the web. It says:
- 3828 lbs curb weight
- 4858 lbs GVWR (1030 lbs payload)
- 36 cu.ft. cargo space (86 cu.ft. with rear seat folded)
- 3.5L V6 engine
- continuously variable transmission
- 5.17:1 differential ratio
As a general rule, you want about 1/3 the resulting vehicle's weight to
be batteries. Let's say you can save 500 lbs by removing the engine and
all its associated parts (gas tank, radiator, exhaust system, etc.).
This increases payload to 1530 lbs, for 1530/4858 = 32% batteries
maximum. So, it is possible to make this into an EV with something like
a 40-50 mile range with lead-acid batteries.
But that would be the proverbial "lead sled" -- a vehicle with all its
payload capacity taken up by batteries. So let's assume 1000 lbs of
batteries as a reasonable maximum. 1000/4858 = 20% batteries. That only
gives you a range of 20-30 miles. Is that enough?
If not, you have to use a more exotic battery (nicad, nimh, lithium
ion), or put the vehicle on a serious weight reduction diet.
So, a lot hinges on what your performance goals are, and how much time
and money you have to put into achieving them.

I doubt it's going to be very impressive when its finished, unless
you've got a load of money for something impressive like lithium
batteries. But where are you? pacbell.net would imply California.

I can host it too; a few hundred megs are no prpblem.
MPEG2 is more common format, but do whatever you can.
You can burn it onto a CD and mail to me for availability
to all of us. Main thing for now is to capture it,
preferrably digitally. Will think about hosting later.

I think I can get a lot of gear donated. I will put 5-7k into
transforming it. I want as much range as humanly possible. I will tear
out the back seats, the spare tire, and all weight reduction I can
undertake. I will bore holes where I can and cut metal and put the
lightest weight wheels on I can find.

Subject: Lawn mower
My 6hp push mower is rusting out. I want to replace it with an electric.
Has any one heard of a walk behind electric mower (SELF PROPELED because of
weight) The comercial models I have seen are so UNDER powered. I would
even build one if there were plans.
I have seen a few of the Electric lawn tractors but the size of my yard
would not be a good match for some thing that large. (turning radius)
