Considering they can only go 25mph, and on nothing faster than a 35mph road, why
not make a big 3-wheeler and license it as a moped (at least in Calif.)? Total
weight can be up to 1500lbs, top speed to 30mph, and there are no road speed
restrictions (short of a freeway) -- don't know how this compares to other
states.

Lets keep a couple things straight... Ot's motors are don't have stone
groves in them....Yours do.
If your motors could stand the amps of course they would make more
torque.
We found they could not. And backed off. Did you want me to vaporize
them??? Oh OK that's your job, I just have to fix them.
Also lets get it clear the I Have seen your back motors suck up 2000 motor
amps. They arc like hell. The left side arcs Green the right side Arcs Blue.
The Gas guys at Bremerton came over and warned me about it. It was that bad.
You Blew them off, I took notes....
So much for 2000 amps.
And lets keep the north and and the South end of my Body out of this thread.

We both want to suck more amps. The more the merrier. But I know that
tossing out fire balls wrecks the motors, and wasted most of the power from
that amps point on up.
The point is to prepare the motors so they CAN and DO pull the big amps with
out Arcing.
And Dennis has not used his brush movment stuff in months, and not at all in
all this years bracket racing successes. He just uses it to dial in a locked
in brush angle. He only uses dynamic movment when he is Record hunting. I
don't think he has made a attempt at a record setting run in years. He's go
his motor so Dialed that he doen't use any of his killer tricks to Braket
race since that would make his run times less reliable.
We could only Dream about having that much control over our motors.
So you break the motors, Rod
Some day I want to go fast.

When I store the car I turn off the pack which disables the DC/DC. The only

Wondered where those got off to. That's the project that finally killed
AVS in Chattanooga. They built a few prototypes to show off. I got to
drive one at the NTRC in Oak Ridge, TN during a conference a few years
ago. I have a few pictures of the thing.
I forget what all the problems were. I recall battery problems, for one.
The microturbine was unreliable, for another. WAY too expensive, for a
third.
Didn't Ebus buy the assets of AVS from the bankruptcy court? I know some
west coast outfit did but I can't recall if it was Ebus. Amusing that the
AVS web site is still up. That "Chattanooga headquarters" building is
abandoned and up for sale.

My "Chinese Junk" scooter came with a 3A charger, recently deceased, and I have
installed a 300w power supply on-board, but I have one problem: the OEM charger
dropeaked at 57.6V (14.4V per battery) but I could only adjust the power supply
up to 56.0V (14.0V per battery). Draining the 20Ah pack until it hit the
controller's low voltage cutoff resulted in 5hr on the original charger before
amps started dropping. The PS is rated at 6.25A output, but I seriously doubt
it will get the job done any faster with the lower voltage end-point...or will
it be even longer?

Who said that? Louis Schweitzer personally?
Either he doesn't even know that Renault already produces not only an EV but also a
serial hybrid (Kangoo electrique and Kangoo elect'road), or he hopes that no one
requests them if he denies their existence so he can cancel them ASAP because of "no
demand".

I wonder what was the last time that Schweitzer was in touch with an "average
consumer"? Thats the most average use of a car: commuting, shopping, driving around in
the city; all short to medium trips perfectly suited for an EV.
Recently I had a chance to test drive the Kangoo hybrid. The Swiss owner drove 25.000
km in about 2 years, and used the hybrid mode on less then 5% of his trips (pure EV
range 80-100km, hybrid range 180-200km for every refill of the tiny 9 liter gas tank).

I have a customer who asked me this, and the answer seemed simple to me, but
the company wants a $1000 for the part so I fear I am missing something. He
purchased a race fuel pump from Weiand, and it is rated at 18amps @ 12volt
(14.2 charge system). In the literature it states that the pumps duty cycle
is only 15minutes, after that you run the risk of melting the armature.
The owner is one of the Canadian entrants in next years World Street Race,
and part of that is 25 mile cruise. His car, the only import entrant, is a
turbo'ed rotary Mazda. Since the turbo won't produce boost on the cruise, he
doesn't need all of the volume and pressure the pump is capable. But he does
need it to last longer than 15 minutes. So the thought was to keep the
voltage high, and reduce the available amps to the motor. Does this make
sense? Any suggestions?

I think you are right on all counts, I believe it was EBus. The
Microturbine has air bearings and gets damaged every startup/shutdown.
I heard only a few hundred startup/ shutdown cycles, but don't really
remember. The later model AVS ultracap/EV 22 foot urban bus (only one
was fully built, I think) was pretty nice. The caps were to reduce peak
battery current and aid in regen capture (thru a big DC-DC) and it was
to be used in a very urban setting. Think airport shuttle for
start/stop frequency and speeds. I think an 80 mile range on ~15kWh of
lead was achieved. That included running the electric doors and such,
too. In a bus that was quite heavy, over 20,000 lbs, IIRC.

Hi Raymond,
What you need to do in fact is reduce the voltage, with the side
effect of reducing the current and power, which will reduce the pump
output and the heat generated. You can do this with a big resistor or
(more sensibly) a small PWM controller, like from 4QD. Bypass this
when you want maximum boost.
Regards
Evan.

hi
i'm new to the group so forgive me if this has been
covered before
i've bought a briggs etek motor for my ev project
the terminals are not marked + or -
does this mean the etek will run in either direction
or is there a rotation direction of preference ?
sorry if this is a daft question but i'm just starting
to learn about evs in general

The report from their website looks like a 70 mile range per charge, but the
efficiencies appear to be low. If they're trying to fight the laws of physics like
Fool Cells, then the result will be nothing. At the bottom it says that the prototype
has yet to work. That's weird, are they lying in their advertisements? They claim they
can get overall efficiencies of 50% with a 3 stage expansion air motor and a 2 stage
heat exchanger to recover the compression and expansion thermodynamic losses. The
electricity efficiency used per charge would have to be better than battery electrics
to make air cars viable. I guess we need some independent analysis on this like was
done by the U of Wash study on Fool Cells.

The problem I experience with the "average consumer" is that they

It won't go 500km on a "fill", hence its not appropriate for me.
Unfortunately, I believe that EVs are a build it and they will come

"Average Consumers" will see them, ask about them, and eventually
they might understand the 90%+ of trips are short argument.
Also the argument that in a multi-vehicle household, not every

And, like many on this list, If I could get a Kangoo here (USA),
I'd have one already!

this problem with big car makers is really anoying
the company i work for runs lpg vans mostly on trips
less than 100 miles per day
we would love to use electric vehicles and are willing
to pay through the nose for them but they are simply
not available
as an iso 14000(environmental acreditation ) company
it makes our blood boil
we are missing out on a great marketing and kudos
device despite being willing to pay extra for it over
the cost of conventional vehicles

Hello and welcome Richard,
I've got twin eteks on my bike. Mounted face to face so they turn in opposite
directions. I've measured current draw on both motors when on my load bench, and they
will pull pretty much the same current when running either direction. I have adjusted
the field timing a tiny bit to get the motors to share the load equally.
Sorry to make a short story long, but I was hoping others would agree and not disagree
with my observations.
Either direction is fine in my opinion.

Darin,
Hi! This is my first post. I've been lurking for about a month now.
I myself just bought an Etek for a go-cart I'm building and was curious
how many amps you are running to each of your motors? I have a 400amp,
48V Alltrax controller. The motor is rated for [EMAIL PROTECTED] which I
had assumed I could go past as long as it's not for very long. Any idea
what the upper limit for amperage and voltage is on these motors?
Thanks!

Subject: Re: etek motor
Hello and welcome Richard,
I've got twin eteks on my bike. Mounted face to face so they turn in
opposite directions. I've measured current draw on both motors when on
my load bench, and they will pull pretty much the same current when
running either direction. I have adjusted the field timing a tiny bit
to get the motors to share the load equally.
Sorry to make a short story long, but I was hoping others would agree
and not disagree with my observations.
Either direction is fine in my opinion.
Darin

Hello,
I need 20 new 6-volt batteries for my Jet Electrica. Does anyone know
of a good place in the Las Vegas, Nevada area to get them?
Thanks,

I find that the heating system for me is three heaters.
1. A under dash cab heater of 640 watts on the
driver side.
2. A under dash cab heater of 840 watts on the
passenger side.
3. A heavy duty industrial engine heater of
either 2000 watts at 120 Vac or 2500 watts at
240 Vac, which heats up the coolant that is
pump through the existing heater core.
All these units can be had from your auto parts store. Here in Montana
where it can get 30 below, I normally used the under cab heaters 90 percent
of the time. Used the water heater system for defrosting the windshield
which the water temperature needs only to be about 50 degrees at times.
The hot water system, takes a while to come up to temperature, 180 degrees,
so I have a on dash transfer switch, that selects commercial power which I
can preheat for about 15 minutes, before I leave. I had to do this only
about two to three times a year.
I had a 2500 watt unit at 240 volts, which heated the 3 gallons of water up
in less then 5 minutes and than short cycle on and off every 30 seconds.
This was too much energy, so I change it to a 2000 watt at 120 volts. I was
been able to used the onboard DC-AC inverter to power it.
The DC-AC inverter than not have to used much, because, After preheating
with commercial power to 180 degrees, and defrosting of about 5 minutes
while driving to my destination, it will retain enough heat after 3 to 4
hours to defrost if needed.
If a person uses hot water heating system, than you should insulated all
equipment and lines with heavy duty pipe foam insulation that has a sealant
on the joints.
In a ICE you normally leaved all the coolant lines uninsulated, but in a EV,
you want to retain as much heating as possible.
It also helps to super insulated the passenger compartment. In my EV, I
have 1 to 2 inches of foam rubber on the floor, 1 inch up the sides, 3/4
inch below the door panels, and two layers of that 1/4 aluminum insulation
that is glue to the top. Also all the foam is cover with aluminum plastic
to reflect the heat back.
My battery boxes are insulated with 5 layers of foam, alum, rug, rug, alum,
foam and rug layer. Has a dark blue rug below a large glass panel that acts
as a solar panel. When its 30 below, I park the car with the panel towards
the sun. After 8 hours, this compartment is still above 70 degrees!

NEVs are not a passing fancy. In the private sector, for local
transportation, I don't believe they are even close to being a fad yet. You
must realize that some NEVs such as the GEM from Chrysler are sold into many
established commercial and industrial markets. You will see them on the
tarmac at airports and on college campuses and golf courses as grounds
keeping equipment. Here in Port Townsend they are used by the Parks
Department and the Police Department. Last weekend they were used to haul
barricades around to put up for the Kinetic Sculpture Race. Some NEVs such
as the California Roadster www.californiaroadster.com. are designed with sex
appeal for only two purposes, transportation and golf. We are planning on
expanding into the retail market and will be selling these as well as golf
carts, scooters, both personal mobility and fun, as well as other DC powered
equipment. I believe Chrysler is in for the long haul. I talk with the GEM
factory regularly. They have set me up with parts and service manuals at no
charge and I do warranty work for them. They would not give this kind of
customer service if they were not serious. Most big auto companies would not
let a non factory trained technician and non authorized dealer be involved
with their products. Since the nearest Chrysler dealer that sells GEMs is
over 100 miles away they are going out of their way to give good customer
service by allowing me to work on their vehicles. I do believe NEVs will
become a fad at some point for personal transportation but it will take way
cool vehicles like The California Roadster to make it happen. This vehicle
was designed with real range as well. It has 72 volts of 6 volt golf cart
batteries. This vehicle has a 90 inch wheelbase as compared to a golf cart
wheelbase from 60 to 65 inches. I believe NEVs make way for the acceptance
of full sized electric vehicles and they are no where near their peak of
acceptance.

Subject: NEVs in Our Future?
Does anybody have any knowledge about where the NEV phenomenon
is heading? Do NEVs have a bright and growing future or not?
Are they still being offered for sale and being bought in significant
numbers?
Or were they a passing fad that came, peaked and tapered off?
