This si the ac compressor I am interested in. I have been doing some
research.
The actual voltage is vague but it appears from some documentation
that it needs a 500V (the prius boosted bus) Variable frequency AC drive
in the 2Kw range.
Also, the motor floats in the oil that floats in the freon so there
is a special oil that can handle the high voltage.
Note to prius owners : toping off your AC with cans of r134 that have
an oil charge in them could cause a spectacular problem or a safety
issue(voltage leakage to compressor body)

For the newest members of the list and the rest of us that are interested,
the following is a summary of this years achievement of the Current
Eliminator V and its owner, designer, builder and driver Dennis Berube:
This is a historic year (2006) for Division 7 of the National Hot Rod
Association (NHRA). Since the NHRA's inception in 1951, all of the top
competitors in it's ranks have run on combustible fuels, this is the first
time an all-electric vehicle has gone this far in the division finals for
bracket racing.
Dennis Berube owns an Electric dragster named the "Current Eliminator V"
(CE-V). He races the CE-V religiously at Speedworld Raceway Park in
Surprise, Arizona. See it at his site:
http://www.currenteliminator.net/home/
Dennis and the CE-V hold the WORLD RECORD in the NHRA for the fastest time
in the quarter mile for an ALL-electric vehicle at 8.801 seconds! The
CE-V is truly fastest quarter mile EV on the PLANET!!!!
***The CE is the QUICKEST EV recorded by Nedra on a NHRA TRACK.
It used just 25 6.5ah lead batteries setting the record.I
also have over 175 other 8 second NHRA timeslips. Dennis Berube Looking
foward to just half the liths Bill has on the kilacycle!!!
Presently, Dennis is "Bracket Racing" the Current Eliminator V at
Speedworld. Arizona is in Division 7 of the NHRA and he is the
current points leader for the "Super Pro" Group. See the latest point
standing, it is posted at: http://speedworldmotorplex.com/results.htm
The next important Local event at Speedworld in Surprise Az will occur on
September 16 at 8:00 AM. http://speedworldmotorplex.com/schedule.htm
This is the final local event of the season for Dennis' class.
*** Just for the record the final race on the 16th has been replaced by a
race on the 23rd of sept.I only need to go 1 round to capture the track
championship.
As a result of this seasons racing, the top 4 from each track in Division
7 (Dennis is guaranteed to be in the top 4) will then go to Bakersfield
California for the Division 7 "Race of Champions" on October 13 through
15. At that race the top 4 from each Division 7 track compete for the
single winner from Division 7.
http://www.nhra.com/aboutnhr/etseries.htm#finals
The single winner from Division 7 will then go to Pomona California to
compete in the overall "Race of Champions" for NHRA Bracket Racing on
November 9 through 12. http://www.pomonaraceway.com/2006/schedule.html
Dennis has as good a chance as any to make it to Pomona California. He
is continually keeping his car in top condition and it shows with the
results he has achived this year. All of us afilliated with Electric
Vehicles can be proud of how far Dennis has taken the CE-V in the NHRA!
For a more detailed explanation of Dennis Berube, the Current Eliminator V
and bracket racing, go to the bottom of the following website:
https://dm3electrics.com/
Background info:
"Super Pro" is a category of the type of dragster and
driver skill level, if you look at the standings:
http://speedworldmotorplex.com/results.htm
- you will see Super Pro is the highest category of Bracket racers,
essentially they are some of the best drivers and cars in bracket
racing.
A "Division" is an area of the country - Division 7 is the southwestern
division. There is one other electric dragster in Division 7 - Tracy
Miller, and should be at the competition in Bakersfield CA on October
13-15. All the other cars are fueled dragsters. Bakersfield will be the
race to find out who is the best in Division 7.
http://www.nhra.com/aboutnhr/etseries.htm#finals
We wish you all the luck possible Dennis!!

I had a similar problem some months ago and even ordered a new pot for the box.
However it was cured very simply. I rarely floor the pedal, this is an important
point.
My car started playing up with jerky acceleration and also surging when I took
my foot off the pedal. At first I thought it was some weird inductance thing
with the pot cable going close to the motor drive cables. In my frustration I
started flooring the pedal (with the key off) and lo and behold next time I
drove it it was like new. It must have wiped the pot clean or something to
travel through its full extent.
Anyhow, whenever I have the problem now I just floor the pedal (with the power
off) a few times and its fixed.
Hope its that simple for you.

One thing I have seen is this:
In applications with little stiction (mostly those that don't use a
throttle cable) the shaking of the throttle pedal wears the element
out at the cruise condition.
On my 914 I replace the pot element about once a year due to this.
It's almost due again since it's getting rough. Probably I'll just
switch to the Hall effect pedal once I build a test bench for the
Hairballs.
Stronger return springs and some friction in the system can reduce
the pedal bounce and therefore reduce the wear.

Hello Everybody,
I install my PB-6 about four years ago, and it is still running perfect.
The PB-6 is install inside a heavy duty aluminum extruded support bracket
that surrounds the PB-6. This is then bolted to another support bracket
that is fasten to the vehicle frame.
The accelerator cable is not directly connected to the PB-6. The
accelerator cable is held in position with one of those carburator brackets
that would bolt to the base of a carburetor, you can get from Auto World or
Jeg's.
A double adjusting rod ends is than connected to the accelerator cable end
and the other end connected to the PB-6.
I did not like the strength of the small spring return that is on the PB-6.
It's the small spring that has a little catch that pushes against the one of
the PB-6 lever stops.
So all I did to increase the tension of this spring, was to rotated the
spring catch off this stop up to one of the corner screws that hold the
cover on the PB-6. Change this screw out with a longer one that goes
through a small standoff tube.
I always like a back up on everything, my whole EV is one big back up. So,
I install a standard spring on to the PB-6 and connected to a bracket that I
can adjust the tension, which is about nothing when use with the PB-6
spring.
When I first received the PB-6, I was alarm at the cheapness of this unit.
I was used to a very heavy industrial super duty water proof unit in cast
aluminum enclosure that have a large adjusting type extruded lever with a
internal adjusting spring and two double external springs.
This thing looks dinky against all the other items on my EV, so I try to
reinforce and enclose it to stabilized it.

Larry who is driving my Toyota torcell conversion and plays bass in
"Brian's" band ( not mine :-) was late for rehearsal Monday night and when
he got there the first words out of his mouth where " one of my guitar
student's dad just bought a Tesla !". I had lot's of questions for him but
seems wife's aren't the only ones that get tired of hearing about EV's and
our leader puts his foot down " NO TALKING ABOUT ELECTRIC CARS WHEN WE ARE
PLAYING MUSIC" . I had to wait till after practice to get the details .
Larry say the guy probable spends more than the price of the car on
landscaping each year , he did show him his EV which I'm sure when you are
getting a Tesla , a Toyota loaded up with golf cart batteries is not that
impressive. Now the big question , how long till he gets it ? will report
as thing happen

As you say, I'm sure that *for them* it was a reasonable choice. Of
course as someone said before, $100K isn't that much anymore.

In a typical system with an accessory battery that's charged off of the
traction pack, the accessory battery's energy store kicks in when power
spikes are called for, such as when lights are first turned on, etc. For
your proposal, then, would you not need a DC-DC converter that could handle
those spikes by itself?
Thanks.

I'm told it's important to have nickel plating over copper interconects
for these flooded nicads I'm getting to prevent corrosion. So if copper
is a 100 on the relative conductivity scale and nickel is a 5, then why
should the great conducting copper be plated with the crummy conducting
nickel??

It seems like one time in the past when the pusher/generator/battery trailer
topic was raised, someone mentioned the possibility of hooking a
motorcycle's front wheel fork to the car's hitch, charging the battery pack
off of the motorcycle engine. I can't remember if the idea was deemed to be
a good one or not. But since many of the generator trailers developed seem
to be using motorcycle-sized engines, perhaps it would work. In addition,
you might not have legal issues, since the motorcycle would already be a
registered vehicle, making running it's engine acceptable. And if you
carried the cycle's front wheel in the truck, then when you got to your
destination, you'd have a bike to travel around on while the car's batteries
were charging off the grid, if need be.
Was there a flaw in the idea?
Thanks.

After reading all this and dealing with the Comuta Van's weak headlights,
I'm sold on it.
Weight is not a concern for me. The Comuta Van is stripped. Running 2 12
volt batteries in series would be good.
Where can I find a 24-12 volt DC to DC converter?

I've been reading about the Hybrid Synergy Drive system in the Prius, which
uses an engine and two motors. One of the motors is in series with the
engine, and they call this the "torque" motor. Can someone give a brief
explanation of how an engine and motor in series work together? When the
engine is running at a certain speed, turning the motor's shaft, and then
you apply power to the motor, does the output speed remain the same but with
extra torque, or does the motor speed up the output shaft. It sounds like
the former, but I want to be sure I'm understanding things correctly.
Thanks.

I suggested that. The idea was to use it as a pusher, which obviously
wouldn't charge the batteries unless you have regen.
The flaw pointed out was that the motorcycle forks would bend, given a
powerful bike and heavy EV. This could be overcome using a hitch that
attached to the frame rails around the engine though.
Or, if your variation is to add a thin generator to the motorcycle
engine whilst leaving it usable as a bike, that's maybe an easier
approach, easier controls too probably. Something like an E-cycle
double motor would work, perhaps.

I guess this is the first in our "family" of ANYbody we know actually

, because say 2 k is a lotta money. But we step up to the plate at

Hi Rich;
Isn't Commuta Van a 60-72 volt system? Ya want a DC to dc that runs off
the total pack, not part of it. I'm SURE the commuta ISN'T a contacter
controller, is it?I know a DC to dc would be tricky on a Cituicar with it's
series parallel setup.I hope Commutas have gone BEYOND that??
Mt two batteries worth

Yes, I had misremembered the thread. My idea here was not a pusher bike,
but hanging a generator or specially-built alternator off the bike's engine.

Engine driven gensets will vary in emissions. Anything you can buy at your
local Home Depot will be a gross polluter. (Yes, I realize that people's
concern for their personal vehicles' emissions varies. I suppose too that
some states/regions are more aggressive that others about emissions laws.)
Some people claim that certain industrial engines can be tuned for lower
emissions. Perhaps true, but none of them is likely to match a well-
designed, microprocessor controlled automobile engine, one which is
programmed to light up a warning light when its emissions control system is
failing. I say this because by law the automakers have a much tougher
standard to meet. It's not much in the nature of industrial engine builders
to meet legal standards that don't apply to their products. ;-)
So, if you insist on using a genset trailer, you can still be relatively
clean by using the ICE from your conversion on it, with all emissions
control gear intact.
The simplest and most efficient means of dealing with the range problem is
to keep an EV for short trips and an ICE for long trips. This is assuming
you have the space and can afford the license and insurance. Alternatives
are to rent an ICE when it's needed, or to share an ICE with someone. This
latter can be done informally, by private agreement, or through a commercial
car-share scheme.

Aren't the Iotas essentially clones of the old Todd chargers? The Todds
were pretty much minimal chargers, built to be relatively cheap, not
civilized. I have an old PC20-LV which I use now and again (haven't for
quite a while) and it makes a HUGE zap when connected to either AC or DC.

For the record, this did not and does not happen.
AFAIK, there is no way to intercept individual posts on this list. There
isn't even anyone watching them go by. You post and when the server load
falls enough for it to cope ;-) your post gets sent to the list. There is
no active moderation.
This mostly works well because we have a fairly thoughful and circumspect
membership. The list owner does have the ability to delete accounts in case
someone becomes a problem. He has used that ability only twice in my
recollection, though he's come close a couple more times.
Bill, If your post didn't make it to the list, it may have been an email
glitch or a server hiccough. But I can assure you, it wasn't the result of
anyone's deliberate action against the post or you.

I am!
We should hook up for dinner and shoot the shEV. I could show you my
project, but it's pretty much a chopped up fiero and a bunch of
drawings at this point, nothing exciting.
Give me a holler at local 990-6996.
And to make this more relavent to the others, last night as I was
biking home I saw right in front of my house my first
on-the-road-under-power EV. It was a e-bicycle, not sure of the brand.
Sort of like an older style upright bike with a box attached to the
pillar under the seat. Looked manufactured, not a conversion.
I mentioned this to a coworker, and he told me he saw yesterday an
old, beat up looking, motorcyle with the "ELECTRIC MOTORCYCLE" as the
license plate. Any other Winnipeggers on the list?

I'm here on business for the next couple of days
qualifing a BLDC motor used for air circulation in

I guess the only EV content is that these motors run
on 27.6Vdc and are also used on my kids go-carts at
48Vdc :-)

The Prius drive system is unique. It's explained fairly well on this page :
http://www.jantzen.nl/prius/Techniek/PowerSplitDevice.htm
I don't think it says so in so many words on that page, but briefly, the
"power split device" acts as an electric torque converter. High RPM from
the engine is coupled to one motor, and its output is coupled through the
inverter to the other motor to provide more torque at low RPM. This torque
is then fed to the drive wheels along with some torque from the engine.
It's a very clever system, but it's important to note that it is not really
designed to drive the car without the engine. A Prius can travel short
distances on battery power, somewhat longer distances with an extra battery
providing more capacity - but in its present form a Prius is >NOT< an EV.
It's a very efficient and cleverly designed ICE car that happens to use
electric motors.

If I wanted to build a kids-sized car (think 3-5 year old), what size of
motor would I need? I ask because we had to buy a new electric weed eater,
because of parts problems with my old (15 years at least) one. The electric
motor works fine. Would I be able to run this on a certain amount of DC
volt, and have it able to run around a 100 to 150 lb vehicle including kid?
(I really don't need another project with all the other honey-dos, but you
have to be prepared.) I appreciate any comments.

That's way too much fire and fun...
Blow holes all the way through Cars....
This would be some added carnage for the 4th of July around here.

Wow, this is a compressor that I have not seen yet. Looks like a Denso-Sanden
compressor body with an electric drive in the endcap on the drive end. Frankly
wondering how they fit a powerful enough drive motor in the small space on the
end but looks like it indeed is a self contained-semihermetic unit. Could be
an awesome find. And the price (250) is outstanding. I wonder if it includes
the core charge tho. I have an e-mail in to them as we speak requesting specs
and pricing. David Chapman.

I have not heard of using DC on an AC motor. There
needs to be a way of switching the magnetic field. In
an AC, it's done more or less at the power plant. DC
does it mechanically (commutator).

Wry note about...
Plug in Hybrids not being a EV...
300 lbs of lead Acid in Ryan's Prius Blue... can go the same miles that 500
lbs of Yellow tops do in Goldie...And without starting the engine.
10 miles of Ev running... in a car that still has it's ICE engine...Very
cool.
So... a Prius can make a darn smooth slow speed EV... on battery power
only..
North Kitsap County is getting used to Hybrids motoring around at less than
40 mph.. without a sound....
So....a Prius CAN be a EV... and we do it often.
This is the promise of a Plug in Hybrid.. EV?, gas??? your choice?
Not the goverment's, Not Toyota's, yours.
Oh yea... I now have 7 Kwhr of Valence 24s in hand... those EV runs in Prius
Blue are going to get a LOT longer...
I think I can stuff 9 of them in the PiPrius's Battery case. That's 11.5
Kwhr... in a car that can run at 175 watt hours per mile...Oh Boy what fun!
I gotta get the Ucharge box running... Or else Mark Koler is gonna hunt me
down with a Oak Stake!

The weedeater motor I salvage is universal and runs fine on either AC or DC,
the problem is it is built to run at 120V. You probably do not want your
kids riding around in a 120V DC toy. The motor will run at 12V DC, but then
you have 1/10 the power available.
Powerwheels are the best deal going for kids EVs. People buy them, kill the
batteries, see the price of new batteries and give them away. Keep your
eyes open at garage sales or thrift shops and you are sure to find one
either cheap or free. Also I would imagine that the cheap chinese scooters
are going to end up the same way. As soon as people kill their batteries
they are going to be looking to unload them.
