See: http://www.heathelper.com/

It switches so the heat can be sent outside in the summer, and kept
inside in the winter.

ah, yes, but are they bright enough to be programmed to vary the tone
according to a external slow clock like a VSS?

Subject: RE: Amps Volts can Kostov take?

  The 'answers' to the questions from David have been interesting to
  read. I know they aren't exactly right because they don't address
  some confusion David has about motors. Not being an expert, these
  comments only address Davids confusion.

  I don't believe the Warp is sep-ex. I believe Randy uses motors in
  heavy duty equipment, not drag racing. Maybe he has a sideline, but
  I know of no one who uses sep-ex for drag racing. The Kostov can be
  expected to put out the same power in industrial service sep-ex or
  series. It does have regen which I think is worth the extra effort.
  Sep-ex is also potentially 1 or 2 % more efficient at the cost of a
  more complex control system.

  The DCP I'm familiar with isn't sep-ex. Maybe, there is a new one. But
  I think there may be some confusion. When you mention 'motor amps' in
  a sep-ex, do you mean armature + field ?  The answers provided so far
  assume we know what you're talking about. For example, are you just
  planning to strap the batteries across the armature and control the
  field ? That certainly isn't efficient. Randy might be able to answer
  your questions.

  What is the "current multiplication" you mention. At low back EMF, the
  series controller kicks out a high current for a few milliseconds and
  turns off. The motor inductance keeps current flowing until the PWM
  kicks in again. This inductive driven current gets through diodes
  allowing the increased current we think you see a 'multiplication'. A
  series controller will not be happy trying to regulate either the low
  field current or high armature current. Certainly, the 500 Amp Curtis
  won't be satisfactory with the big Kostov.

"Yep, you got it right both ways -- you could do it with current
multiplication, or do it with none. I haven't totally settled on a
control system. If the idle speed were not too high, I would not mind
slipping the clutch to take off. This could be as simple as a
variable resistor in the field. At the high end, I could use two
controllers, one for the field and one for the armature."

  This made no sense in context and a study of available sep-ex controls
  would be a good move.

     "Two get less stressed"

  If two motors are 'less stressed', then they aren't being used right.

     "Two seems to be the NEDRA trick of late"

  If it's fashionable, then there might be a reason.

"I'm hoping that going sepex helps with the last two points. I think
alot of the stress the motors get is from current multiplication."

  That would be an earth shaking discovery.

"Getting the same torque for less motor current I'm hoping gives good
power without fireballing."

  A motor is designed for either a high current and low Voltage or lower
  current and higher Voltage. Then you go racing and push the limits
  until the motor gives out. This is not a reason to use sep-ex.

                      "I tend to simplistically think of motors as
fuses, too much current melts them. I do know if you get too much
voltage, arcing can destroy things pretty quick. And, of course, high
voltage enables higher currents, more heat, and higher rpm, that can
destroy motors. Guess I'll just have to turn up the wick a little at
a time until I see arcing or smell something burning. :)

  The Volts that cause arcing are across the armature comm bars. At high
  rpm, There is a back EMF you don't see or measure unless you want to
  know what's going on. The Amps across the armature cause the Volts
  that do the arcing.

                                                      "I'm planning
on staying in known voltage regions (240 to 336 V), and maybe twice
"regular" current (but only 1/2 of Wayland current) levels, but with
sepex hope that motor current is actually more modest than a "600"
amp controller doing 3x current multiplication."

  This doesn't have meaning. The sep-ex motor is wound differently and
  for a different Voltage and different Amps in the wires. You won't
  get more power from sep-ex.

  I'm waving my hands 'stop'. Find out what real life can get out of
  these motors.

"Certainly, the input power is very close, between sepex and series.
As you said, sepex puts more current in the field,..."

  Perhaps more Ampere turns, not many.

"....giving more torque,..."

  At lower Voltage maybe, but not more Power.

"....and series recirculates the current (current multiplication)
to give more torque."

  No. At lower speeds, the series motor traditionally gives more torque,
  but that is a design function.

"This is more pronounced at low RPM, and motor
current = battery current once in current limit mode, for series.

"So here is where the handwaving starts... Say at stall, it seems that
having 1800 series motor amps has got to be tougher on the motor than
sepex 600 amps, no matter what the voltage. Same power in, and same
power out, in both cases. Haven't some of the NEDRA guys zorched
their motors on the starting line?"

  This is meaningless. You are missing some important numbers here.

"I think the basic debate is this: Is voltage or amps more harmful to
the motor? I'm taking the amps side (for now at least :) ). I do
realize there are many NEDRA racers that pour alot of amps through
their series motors, and they keep ticking."

  No debate; the excessive motor Amps that go along with excessive
  armature Voltage causes arcing. Racing gets more arcing than not
  racing and this is exponentially worse the more sincere you are.

"Fireballing/racing is not the only motivator for sepex. Another is to
do something a little different from most, kind of a research
project."

  Berube and Rudman are researching advance. That's interesting. But
  they know what they're doing.

"I also want regen, home of the 2002 Winter Olympics has some
serious hills."

  Good reason. And the car can be fast, but you won't play with the
  other suspects with sep-ex.

     Hi  Mike;

    OK I'll desist, althought yu wouldn't catch me dead on the turnpike in
that thing at 55MPH, or maybe you'd see me dead, out there, after being run
over by an 18 wheeler that is practicing for the next "Cannonball Run"
Snowing today here in CT All the radio is talking about is jackknifed 18
wheelers. It should be fun, NOT, going to work in awile. Going in the gas
mobile as I HATE caked salt an' snow in my Rabbit. As it's an old car
already, don't need to help it's natural aging process any more than I
hafta. It duz FINE in snow, BTW, Smooth electric power gives ya nice
traction in slick stuff.

    I guess a Think could be called a Mini-car, too? Wouldn't have a problem
turnpikin' to work in that, although I would be in the Rite lane all the
time. But it duz evoke comfort in it's decent handling. Right, You Thinkers,
out there? I was impressed with how it DODN'T feel like the minicars of old.
I nearly lost it years ago on the hiway in a Borgward, mini something at
about 55 , it just started to wallow all over the road. I needed two lanes
awile to haul it back under control, much to the amusment of the other kind
folks that got out of my way for my acrobatics. A family friend had a
penchant for wierd and strange cars, back in the 50's He would turn up with
Borgwards, Isettas, Fiets, and a Cool one that sounded like Porch, front or
rear? THAT one  was 'Way cool, I LIKED that one! Dad said it sounded like
the garbage truck, and ran out with the garbage one morning when he came
over in it. I even got to drive it, a Speedster, I think it was called. Sure
drove different than the family Roadmonster , by Buick, that we had!

     Great! Thanks for sharing a useful service or source with us. Yeah it's
a perspective thing. I had to buy a Fuel Pump for a Honda Accord, cost about
the same. Miss the old Ford style that runs off the camshaft, cost about 15
bux.Like the Bug had.

I was redesigning a bipolar transistor control that had a nominal PWM frequency
of 750 Hz. When the truck went into the plugging routine (motor braking) and reached
zero speed, the accelerator could modulate the PWM frequency. I never learned any
tunes, but a musically inclined person could of done quite well with this 10,000 lb instrument.

You already have the "amplifier" in an EV. Just alter the PWM frequency for the controller. You could program the controller to play any tune you like. It would get loudest at 50% duty cycle.

 Sounds like the DynaStart used on my Isetta.  It's a generator, not
 an alternator though.  Back to those expensive brushes.

Marvin,

Find a local EV-1 or S-10E owner and ask him/her to bring a
MagneCharger by for a day or two. Wire it up, have the guy fire up
your meter, then yank it down and re-wire your
receptacle. Alternatively, you can threaten them with the idea of
going to the media about it. A local news station would probably eat
up a story like that... *trying* to do something about our environment
in a big way with two EVs and several other things, yet still getting
screwed by the system. Yeah, you'll get a story out of that! ;)

You'll soon have two EVs registered in your name... do they really
think your goal is to get off-peak rates for a washing
machine??? (rolls eyes)

 I understand it is not terribly efficient, but what is the efficiency of
creating Hydrogen gas from water.

ie: if you could use waste heat from normal day to day processes., couldnt
you generate elec off of this, and store it hydrogen to be released later?

I understand that "why not just store it in a battery and use that..!"
argument..
but i was thinking more along the lines that you could have fuel cell
generator on board.. for longer trip/emergency usage.  without having to use
smelly old gas etc

why not just install a radiator in the path of the dryer exaust.. and  route
inside air through that..heating clean inside air.

my dad used to do the old sock and route the air back in to the house..
we didnt notice sauna activity.. since we had the heater on too...  dried it
up..

what was most annoying was teeny tiny lint everywhere..

If your house had enough people.. meaning that you
basically run the dryer 8 hours a day..due to the clothes load..
  could you use thermo electrics to atleast help in your ev charging?

same as on gas heater vents..


or is the amount too 'piddling' to deal with.

Hey Sheer!

You really gonna do it?

You already know that I think that this is a great idea.  :^D

I believe there is a wide market for this.

All kinds of toys could use it, the golf car market could be substantial.
(if they will buy bodies that look like Mustangs, VWs, and Rolls Royces they

will buy anything.)
Anything that spins could be made to work with an RPM pick up.

Make it run off 12vdc and easy to jack into a sound system.


Top Ten Sounds?

1- George Jetson's car (I bet this would be number one with EVers)

2- Nitro burning top fuel dragster

3- Indy car

4- Jet aircraft

5- Helicopter

6- Curtis 1231  :^D

7- Model T Ford

8- Big-Bore Crotch Rocket

9- Locomotive (steam, w/whistle)

10- Briggs and Stratton Mini-bike


OK, some of these ain't the greatest, anybody else got some good ones?

Hey Lesley:

I too was perusing those particular documents, and I too could not find
anything "official" banning an EV for simply being conductively charged.

Probably just another instance of a well-meaning yet clueless bureaucrat
trying to toe the official line to the best of their ability.

Instead of waking the sleeping beast I think I'll lay low. If it becomes an
issue I will take them on using their own documents.

I have a friend who's an ADA for LA County, and I have contacts in the AG's
office. As a redneck with a college education, computer, printer, and reams
of paper, I don't want to become anyone's personal worst nightmare but....

I really don't think anything will come of it. Probably all my fault for
even mentioning it. You know how it is. Never give any authorities any more
info about anything than they need for you to get your little piece of
official paper.

And you know what the biggest kicker is? I have a gas dryer.

And this certainly doesn't make you a bad fella. It's like David Bowie said:

and they wrap your first one with your birth cert when you leave the
hospital. No, I'm scared of people who believe what they see/read in the

And you must be one cool Kiwi to quote Mark Twain.

Sorry but after compressing the hydrogen it will be a very expensive fuel.
Energy wise that is.  Might as well just compress air and run on that.  I
just hope that the Lithium, Flywheel or a Zinc/Al-air battery happens.  The
enery use will be much less going  to a battery. Of course if you are just
converting hydrogen from your PV and maybe have a windmill to compress it
might work.  The oil companies are just wishing that battery cars will go
away.  250 pounds of hightech batteries will be more than most people will
need to go a long way.  Fool cells are complicated enough to make another
another high profit maintainance stream for the auto companies.  The oil
companies are just itching to get another hight profit fuel and hydrogen is
very much like gasoline.  Better for us though.  It's safer and you can make
it yourself. Interesting to see what happens... Lawrence

The only thing that comes close to your request is an
electrolytic
zinc regenerator.  It plugs into the wall and
regenerates spent
zinc fuel cell oxide back into zinc.  The availability
of these is
very tenuous, but keep your eyes open.  Maybe in the
distant
future...

Anybody using Zinc air.  Seems a lot of tests are going on.  I am still

Do you get credit on that line for the PV or do they just give you credit on
the house line?  Can you back the TOU with your PV.  What I am looking for
is getting credit at the 22 cent per kwh day rate and using at the .04 rate
at night.  Lawrence Rhodes....

--- Begin Message --- Awhile back, Victor Tikhonov noticed that his PowerCheq modules were not keeping his batteries balanced correctly. Each successive battery in the string had just a bit lower voltage than the previous battery in the string. I've been looking at balancing systems for a consulting job, and I have been giving these sort of issues quite a bit of thought.

Last week, I was talking with Steve Ciciora and Rich Rudman about battery balancing, and I think we have solved the mystery of Victor's PowerCheq modules.

The key is that Victor has remotely mounted the PowerCheq modules using a wiring harness instead of directly connecting the leads to the battery terminals. It is a "common" mistake (excuse the pun) to use just one wire per battery in such harnesses. You must use (at least) two wires per battery. Otherwise, modular balancers (including both PowerCheqs and Rudman Regulators) won't work correctly.

The issue is the voltage drop on the "common" wire shared by two modules. When module "A" passes current through the common wire, the voltage drop upsets the voltage reading that the adjacent module is trying to make. You can't measure battery voltage accurately if there is current flowing through either of the measurement wires.

There are two ways of getting the system to work properly.

1) Relocate each of the modules to the battery it is regulating and connect the leads directly.

2) Re-wire the remote modules so that each module lead has it's own, separate, harness wire and fuse.

The fuse must be near the battery and must be rated for the full pack voltage, otherwise there is little point in installing fuses at all.

I was just referring to the amount of energy that entered your home. The
burner on a gas stove has no vent, so 100% of the heat it produces goes
inside the home. Same for an electric stove; 100% of the heat it
produces goes inside. Thus the stove is more efficient, energy-wise,
than a 92% efficient furnace.

Certainly true. However, I don't know the transmission efficiency for
the gas, electric, or other fuels being considered.

If you try to include the efficiency and pollution produced from
obtaining and transporting the fuel; operating the generating plant or
refinery; and then transporting it to your house -- the picture gets so
complicated that it becomes nearly impossible to come up with a definite
answer.

Yes; it is probably more efficient. But efficiency may not be the most
important aspect. For example, pollution may matter more than
efficiency. If your electricity is generated from burning coal, and your
alternative is natural gas, then gas is cleaner (lower pollution). But
if your electricity is generated by hydro power, then it pollutes
less.

It could. Heat pumps can have "efficiencies" of 200%-300%. I'd guess
that a 300% efficient furnace would more than compensate for a typical
power plant.

Chrysler just happens to make lots of big cars and trucks, and not many
small ones. If they had included GMC or Mack or Freightliner, etc. they
would have been at the bottom.

This would work, too. The charging diodes wouldn't be very big at all.
The discharge diodes would be big, but not unreasonably so -- you can't
run at all that high a current for very long. You can use Schottkys,
which have half the drop and thus half the heat.

A possible concern is that nicads have such low internal resistance,
that if they were at different voltages at the end of a charge cycle,
simply switching them in parallel might lead to some alarming peak
current surges.

I think I would just charge each parallel string with a resistor in
series with each (light bulbs, or perhaps a couple of blowers :-) That
way, they could run at slightly different charge voltages, and when you
stopped charging, the resistors/bulbs/fan motors would let them
gradually return to the same voltage before you closed that contactor to
parallel them. And, if something went wrong so the two strings wouldn't
equalize (shorted cell or whatever), the lights/fans would give you an
obvious warning.
