On one hand, I can see why this is exciting, but on the other who cares.  It is 
no longer and never again will be a production car, it will never serve any 
practical purpose, so while this is a nice piece of nostalgia it does no one 
any good.

If you want an EV of your own you've still got to build it yourself...

No, your load would be from one primary lead to the other secondary
lead; your load is not connected to where the primary and secondary
connect.

Also, the transformer has a polarity. If you hook it up forwards, the
voltages will add; if you hook it up backwards, the voltages will
subtract, leaving you with (120-12)=108.

The easiest way would be to hook up the transformer in series, with no
load, and measure the voltage with a voltmeter. If you get less
voltage across the output (pri-sec in series) than wall voltage,
switch which secondary lead is connected to the primary.

Yes, basically. However, we are actually implementing the Vcorrection
blocks ourself. Each one is a very basic isolated power supply. The
secondary side simply consists of the secondary of a transformer and a
diode for rectification. The primary side consists of the primaries of
all (30) transformers in series and a switcher. We're also looking at
a method to return the reset energy of the transformers to the bus.

The design isn't yet complete, and it hasn't been built or tested.
That should change within the next few months, though.

Thanks, that makes sense.  Also I did some poking around and found this 
http://www.acmepowerdist.com/pdf/Page_104-109.pdf  which has a nice description 
and diagrams.

Hi Rod etc.
 
I checked with Bill as to why my report/photos were not on the www.evworld.com 
website yet and he emailed that the report would be dribbled out in articles 
over the next few weeks with photos.  It's really a 14 page report (I was asked 
*not* to publish on the EVlist) and about 150 photos.  So probably due to it's 
size it will be edited and sectioned over some articles.
 
BTW, Consumer Reports just did a test on NITROGEN filled tires and said to save 
your money, the difference in air loss over 6 months was insignificant.  Just 
carry a 1lb 12V air compressor with you.
 
With regards to the Saft-Johnson controls statement that the Ni-Cads die like 
other batteries, just take longer.  I don't know if it's true since I'm not a 
chemist but I can't imagine anything that gets used not wearing out over time.  
Of course on the other hand if they could easily be rejuvenated and people knew 
that, Saft (bought out by Johnson Controls) would not make as much money.
 
Have a renewable energy day,
Mark

Excerpts from our Dec 11th meeting....
-------------------------------------------------------
Dec 11th SEVA Meeting

Well Santa really came through !!  I mean in SPADES !  It was cold, yes, 
dark, and before it was all over it rained, but nothing could have 
spoiled the, ( if I may say) ELECTRICITY in the air.  There she came, 
not 8 tinny reindeer, but a huge motor home belonging to none other than 
Dr. Seal, former chief of the famous Vehicle Research Institute of 
Western Washington University, Bellingham (retired) .    And what was he 
dragging ? Not a sleigh, but a WORKING MODEL of the infamous GM EV-1 in 
silver blue-gray.  After over 2 years of poking, hacking, rewiring, and 
help from dozens of volunteers, and help from our very own SEVA friends, 
Stephen Johnson, and Paul Peavyhouse, the car moved under its own power. 
  The crowd cheered as she moved into position for display, and Dr. Seal 
sat about explaining the long arduous process.  Watch the Moment of 
Triumph at YouTube: http://www.youtube.com/watch?v=IA9jD8NIr4Y Dozens of 
pictures were taken, and our very own Ryan Fulcher is preparing a 15 
minute video of the momentous occasion.

As if that were not exciting enough, Daniel Davids met a couple last 
week, from the Seattle area who have actually ordered a TESLA Roadster. 
  They came to our meeting, talked at length about the ordering process, 
and told us they were expecting delivery next year.  Also they were one 
of a few who have been invited down to California to actually drive the 
TESLA.  Their descriptions left us on the edge of our seats.  But even 
more interesting than that, is that they know of almost 20 others in the 
Washington area, who have also put down $50k for their very own Tesla. 
Also they explained that before 2009 roles around there will be a Tesla 
Service Point in the Seattle area ( if all goes well).

Thanks for the information. I will have to watch out for a transformer 
that will work. I had a transformer that would have worked with a 26 
volt secondary laying around for a few years, threw it away 2 weeks ago 
because I didn't have a use for it.That's the way it goes.

Hi Folks, I have seen it , it stopped by my house on it's way back to 
Washington.
It has the original drive and batteries, Seems that when GM was 
destroying the EV1s they forgot about all those GM electric S10s still 
around that they could not get back.
The following is from our local EV group.  Bill

### THE GENERAL MOTORS EV-1 LIVES!
an ATC eNews EXTRA!
12/11/07

RENO, NV -- Jaws hit the pavement at the Renewable L.A. event
<http://www.renewablela.org> in Van Nuys, California, last Saturday
when an EV-1 made an appearance -- and it arrived operating under its
own power! <http://tinyurl.com/2xp7jo>

The EV-1 was made operational by a group working under Mike Seal
<http://tinyurl.com/2hbajz> & <http://blogs.edmunds.com/.eea11e9>. Mike
is professor emeritus and founder of the Vehicle Research Institute
<http://vri.etec.wwu.edu/>  at Western Washington University in
Bellingham.

And then on Monday my jaw hit the floor when Alternative Transportation
Club (ATC) member, Bill Brinsmead, called and told me an EV-1 was on
its way to Reno! I don't have the whole story, but it seems that Bill,
being in the university business, was aware of the project to rebuild
the EV-1 so he graciously offered to donate an EV-1 "gas-pump" style
inductive (paddle) charger he owns to professor Seal's group.

Unfortunately, there was no time to contact anyone about the EV-1's
arrival in Reno on Monday. We did not know exactly when it would be
here or for how long and I was committed to other business.

However, my other commitments placed me near Bill's home where I was
told professor Seal would be picking up the charger. So I took a chance
and dropped by. To my surprise and delight I found the EV-1 parked in
front of Bill's house! (It was actually on a trailer being towed by a
motorhome.) Bill was not home as he and the professor, et al, had gone
to lunch.

In any case, the pictures I shot are located at the following URL:
http://ElectricNevada.org/pics/ev1

And here's another video of the restored EV-1 at Saturday's event in
L.A.: http://www.youtube.com/watch?v=UjKG5bVeCDs&NR=1

Be well,
Bob

Hi Damon & All,

Yup, those would be thems...:-)

Here's a picture of one (lower right-hand corner) feeding a 144 VDC
pack's "bad-boy" charger (upper left-hand corner)
