It could happen! I know I'm going to try and repeat it. Maybe take a
leason from the derby team and put magnets in the front bumper.
The truck does have reasonable rolling efficiency. But this morning
was rediculous :)

Mostly wrong. You used to be able to import a vehicle, what they used to
call a "grey market" vehicle. It still had to meet certain DOT specs for
the year it was made, but I think it was exempt from emmision control
specs. I remember when I was in germany 20 years ago you could still do
this, but it had to go through a bonded converter that would add stuff
like DOT safety glass, etc.
>From what I heard this option has since been eliminted.
I think you can still import vehicles, but they have to meet the US specs
for the year they were built.
However, if this was imported as a NEV, then the requirements are
rediculously easy to meet.

Now we know where the images were taken. All the e-bay photos are on their
website. Why would they advertise the car in Kansas, unless they import them 1
at a time under personal exemption and are trying to sell them individually.
Of course this country wouldn't be friendly to them flooding our streets with
cheap efficient vehicles. If they don't cost $1million to build our big
manufacturers think they shouldn't be on the street. I hope that if someone
looks at this car in Kansas they can get a feel if the marketing tactic is
legit.

Hello Dave,
Must have some ESP here.
My Zilla is 6 inches above the motor mounted on a chassis that is supported
with brackets about 8 inches from the firewall.
My cables are 2/0 from the Zilla to the motor, with one that is about 2-foot
and the other is 1.5 foot, non-twisted.
I use copper buss bars from the contactor to a shunt using heavy duty heat
shrink over the bars that gets about 1/8 thick when install.
But I did run 2/0 cables to the Zilla bars. I use the heavy duty cable lugs
on Compact 2/0 conductor (not welding wire) which has larger strands then
the welding wire, which is about 500 strands 600 volt rated. We use a lot
of this wire in our electrical work. It can be bent at 90 degrees which it
will stay in that angle.
This wire has a thinner insulation, not design to be pull over the ground
like welding wire with its thicker jacket, but is used in enclosures and
chassis work.
I also used the heavy duty heat shrink on these terminals. Had to install
them on the Zilla buss bars with the lugs turn around so the terminal lugs
barrels would not touch each other.
The heavy duty heat shrink on the terminal lugs are only 1/4 inch apart.
The Zilla Hairball is place about 1/4 inch above the Zilla motor controller
that is mounted directly onto a 1/4 inch aluminum chassis plate which is
then mounted with stand offs from the back of a enclosurer. The main
contactor is place 2 inches to the right of the Zilla controller.
This aluminum chassis plate is counter poise grounded to a ground buss
system that runs around the EV. Each component that is place on this
chassis plate has two grounding jumpers to the chassis plate ground points.
I have no noise at all on the AM or FM.

There is another film on youtube called "the making of rendevous" which
I can't watch now.
Someone watch it and tell us what it says was done.

That kind of image stabilization is easy with the vibration isolation

The tire squeal came from the same sound bite each time. Tire squeal
changes depending on oversteer or understeer. It never changed during
the video.
Still a great video. Just a little amatuerish in post production.

Rendezvous is indeed a famous film, but the scary thing about it is
not
the driving, but just how bad most peoples observation must be to not
spot the fact that the film is a FAKE! If they drive on the road with
this lack of attention then help us all, although part of the problem
is
that you want to believe. The VERY first time I watched this I thought
it looked wrong.
The car is meant to be a Ferrari 275 GTB, but there's no way you'd
get a
picture that steady using a 70's Ferrari as a camera platform. It even
smoothly mounts a kerb at one point. The car also shows no sign during
the film of any oversteer, so definitely NOT a 70's Ferrari! The
soundtrack is very well done, but there appear to be SIX upchanges
during one sequence. NOTICE how there is little reaction from other
vehicles or pedestrians!
MOST damning of all and absolute proof;
The sequence along the Champs Elysee takes about 1 minute (taken from
the DVD time signature) and the distance travelled is approx. 1.6Km or
ONE mile. Now even with my maths, one mile in one minute is 60mph and
this is one of the fastest sequences in the film. A friend of mine has
been in a convoy of Minis doing that speed along the Champs Elysee in
middle of the day!
As for running red lights? Well, this is Paris after all, the road
markings and lights are really only suggestions.
The car is almost certainly a Citroen, either a CX or DS, but I
suppose
it could have been an SM. Even with modern electronic image
stabilisation a Citroen with oleo-pneumatic suspension is still a
popular choice as a camera platform. The camera was mounted very low
and
the soundtrack is very well done, but watch it as if you were the
driver.

In the show "cool fuel roadtrip" on cable this year an australian
traveled across America on any vehicle he could find that Didn't use
gasoline.
On vehicle he borrowed was an electric harley . The batteries and
electric motor took the place of the harley engine.
He also flew in a n ethanol private plane biodiesal vehciles etc.

Perhaps you heard a different interview. I remember him saying that
they had specifically tested "setting fire" to individual cells in the
pack and that it did not propagate or cause a safety problem. What
more do you want?
Although this issue has been known for a while with laptop's we still find
this issue happening with them and with far less cells.
Laptops. Until the recent "defective Sony cells" problem with Dell,
Apple and Toshiba laptops, I can't actually remember hearing about any
laptop fires. And there are a lot of laptops out there.
In reality the myth, with no real supporting evidence is that Tesla has
totally fixed the problem. The fact, as I've clearly shown in an earlier
mail, is that this problem is most certainly not a myth. Dell / Toshiba and
Sony know its not.
Unless Tesla are using the same cells that are causing the laptop
battery recalls, I don't see how you are making the leap to assuming
that they too have this problem.
I love what Tesla are doing but I also want to be realistic, I hope they
have totally solved this because if they haven't they might well have handed
the usual suspects the murder weapon to kill another electric car.
I think it's more likely that alarmist conjecture about exploding
batteries would kill them, rather than any actual problems. There's a
lot of money involved there, and I don't think the people investing it
want to see it go up in a puff of smoke.

Hi!
I recently was doing some research into the component design for an ev and have
a question on contactors that I haven't resolved yet on the research I've done.
For the starter contactor, basically the one that when you turn the key it is
activated so that the battery pack power is now connected to the motor
controller, would you use an intermittent coil-type contactor or a continuous
coil-type one?
The item I'm looking at is the SW-200 Single Pole Single Throw, Normally Open
contactor from:
http://www.tecknowledgey.com/catalog/product_info.php?cPath=57_61&products_id=530
They said they only have the continuous coil-type in stock and not the
intermittent. I was a bit confused as to which coil-type is used in normal EV
conversions for the starter or other contactors.
If you can answer this question, I'd be more than happy.
Thanks so much!
Sincerely,
Adan Vielma

I just came across this article from 1993 in Mother Earth News:
http://www.motherearthnews.com/Alternative_Energy/1993_June_July/1993_Update__Dave_Arthur_s_Amazing_Hybrid_Electric_Car.
What got to me so upset was that they had 60,000 requests in one
year for the plans.
My view on the article is that it not exactly wrong, but rather wildly
optimistic. Mother Earth New's reporter is just as bad, blandly
accepting it all with wide-eyed enthusiasm.
It's also a sad commentary on the state of the knowledge of the American
public. I suspect that 60,000 plans were requested because the average
person can't tell the difference between fact and fiction. Everything in
the mass media is advertising, which depends on exaggeration, selective
use of the facts to mislead, and even outright lies.
Lying has become so bad that it endangers the truth. If you have a
product that really does offer a 10% improvement, how do you advertise
it? If you say "10% improvement", your competitor's ads will lie and
claim theirs provides a "20% improvement". When the customers can't
measure it for themselves, and there are no independent testing
organizations to police the claims, they win and you lose!
In the extreme, I think this is what leads to so many outrageous claims
for superbatteries, miracle motors, and impossible gadgets of all types.
Why NOT make incredible claims? Your customers are too stupid to know
the difference!

This reference makes the usual mistake of ignoring capacitor and switch
resistances. It therefore comes up with an erroneous efficiency. Though
the author did build and test a model, he made another common mistake
and used a low-frequency power meter to measure efficiency; it misses
the high frequency pulse nature of the currents in these converters.
http://www.smartsparkenergy.com/pdf/switchedcap.pdf#search=%22magnetic-less%20DC-DC%22
This reference does a much better job. The author does include the
effects of capacitor and switch resistances. He then goes on to discuss
the consequences of these resistances on performance and efficiency. He
also used the capacitor's inductance to mitigate the effects of
capacitor ESR.
Finally, he built a working model to test his results. With four 0.06
ohm MOSFETs and two 180uF 0.0175 ohm capacitors, his actual output
resistance was 1.2 ohms (16v at 0 amp, 14.8v at 1 amp). He didn't
explicitly measure efficiency, but from the data it cannot exceed
14.8v/16v = 92% at 1 amp; it will be lower when the power consumed by
the control circuitry is taken into account, and would worsen at higher
currents.
Now, this is good performance for a flying capacitor circuit. However,
the efficiency is no better, and the number of parts and their cost is
significantly higher than an equivalent normal boost converter with
inductors. Moreover, the boost converter provides a simple way to
regulate output voltage; the flying capacitor circuit has a 1.2 volt
difference between voltages it is supposed to be holding the same.

Adan,
Those are good and fairly typical contactors to use for main power switching up
to 144Vdc. You will want the continuous rated coil since it will remain
energized continuously as long as you have the key on.

Lee hit the nail on the head.
Then when the customers learn they have been deceived by the false
claims the whole industry gets a bad rap and everyone associated with it
must be a scoundrel. Now they are unwilling to trust the guy who claimed
a truthful 10%.

So it's an old guy talking to a young guy the whole drive. They
stopped at lots of lights and drove what looked to be near the speed
limit. So there was some video wizardry as well.

60 milliohm fets? Man, those are lousy. Would the efficiency be that
much better with 6 milliohm fets?

You may want to pay close attention to the field of view. Typically the
ones with a tighter field of view are more desirable, as is having a
laser pointer.
When the field of view is wide, you must be closer up to small target
objects to take only the target's temp. If you're too far away, the
sensor will see some of the background and the reading will be part
target and part background.

Hi,
I've been trying to measure various temperatures on high voltage parts while running and found this little gem at Harbor Frieght for $40 model 91778. These laser pointed non contact IR thermometers used to be around $200. I measured internal circuit board traces for beefing up and commutators/brushes while running.
Disclaimer: I'm not affiliated with harbor Frieght and neither is my grandmother.
Cheers,

"The problems Dell is having stem from impurities within the anode and

pieces of metal, can work their way to the edge of the anode or
cathode and rupture the isolator that sits between the two. Once that
happens, you get a short circuit and possibly a fire."

Actually Lee most of my customers are quite intelligent and a lot of them
are on this list :-)
I do really appreciate your comments Lee. I just couldn't help but to give
you a little jab on that statement just for fun.

I just came across this article from 1993 in Mother Earth News:
http://www.motherearthnews.com/Alternative_Energy/1993_June_July/1993_Update__Dave_Arthur_s_Amazing_Hybrid_Electric_Car.
What got to me so upset was that they had 60,000 requests in one
year for the plans.
My view on the article is that it not exactly wrong, but rather wildly
optimistic. Mother Earth New's reporter is just as bad, blandly accepting
it all with wide-eyed enthusiasm.
It's also a sad commentary on the state of the knowledge of the American
public. I suspect that 60,000 plans were requested because the average
person can't tell the difference between fact and fiction. Everything in
the mass media is advertising, which depends on exaggeration, selective
use of the facts to mislead, and even outright lies.
Lying has become so bad that it endangers the truth. If you have a product

Is there a difference in daisy chaining dual pole contacts directly in series
on one power lead vice wiring each pole to a power lead and switching to
separate sides of a load. Take for instance my heater element. If I were to
switch only one power lead with dual poles on the contactor daisy chained in
series I can increase the contact voltage rating. Is the same true if I use
one pole on the + lead and 1 pole on the - lead of the ceramic heating element.
If the added contact voltage rating is still valid then would I have to put a
separate snubber on each contact instead of 1 snubber circuit across the series
pair?

The problem in Phoenix is the temperature can reach 115F and this is
read in the shade. If an EV was parked it would still require cooling
which would use energy. The "storage rating" of the Li-Ion can be
exceeded just by sitting in a sunny parking lot.
I do don't want an expensive lesson in "no-no's" with Li-Ion and high
heat areas.
Is there a Li-Ion user in Phoenix that can provide guidance?
Thank you for the comments.

How do you figure? It is an ev - batteries power the motors, they are
charged by the fuel cells. No ICE components involved.
By that measure all the other evs are OT because they are coal powered.
This may be a technicality, but it seems to
be the source for flames, too (eek). That a Fuelcell car gets 300 miles
of range on an
'obtainable' fuel is meaningless.
Only meaningless to the closed mind.
Sorry to bring up an advance, everyone already knows everything is in
full agreement.
I think the real problem isn't evs, its EV'ers.
