I agree on paying fair share.  The problem is we are cutting new ground
here and a lot of these issues just haven't come up before.  I am
sending an email to my local congressman to see if he is doing anything
law wise to asses taxes for EV cars and people who are making their own
fuel.  I don't want to end up being fined for not paying road tax.

Subject: gas taxes...

1) guy converts diesel to run on veggie oil.
2) NC tax people come after him, wanting his first born, for "tax"
reasons.

The gist of my concern (in the article) is:

Folks that use the road, have to pay road-use taxes, which are bundled
into the price of gasoline and diesel.
Of course, Electric Vehicles don't pay this tax....because we don't use
gasoline.
Moreover, vehicles that get better fuel economy pay less tax (I found an
article about that - be prepared in the future for the DMV to begin
retrieving our odometer readings for miles-driven taxation purposes; who
knows, probably already happens in some states, and certainly does for
"business" or personally owned "business use" vehicles).


Here's the math (its simple, even I can do it).
Average miles traveled: 12000
Average MPG (for my camry): 22
Thats ~ 545 gallons.

NC charges 29.9 cents a gallon (according to the article).
(I'm sure its more like 29.999 cents)
.299 * 545 = ~ 162...
Thats $162 a year in taxes (NC State)
This website
http://www.gaspricewatch.com/usgastaxes.asp
indicates Federal tax is 18.4 cents per gallon.
18.4 * 545 = ~100.28

(What are the federal and state taxes on our electric bill? I donno,
haven't looked; I would guess that this *could* be subtracted, to keep
the SOBs in government totally honest).
(note: I don't like big government; I could go on, but I doubt you'd
appreciate it).

Anyway.

The article states that this guy is getting charged $1000 fine, for NC
state taxes (what about county? city?).

Either way, I'm concerned.
(Finally) - Here's my question:

Are the Tax people going to come after us (I use "us" as a generic term;
us EVers, or more specifically, us NC EVers...) because uncle thief
wants more tax revenue?
What recourse do we have (federally, or statewise) - if any?
Has anyone heard of this happening before?
Do we get rewarded (pay less tax) because we're trying to "save the
environment" - "protect the US from terrorists by not giving them money"

(etc, pick a reason for why you drive electric).

Additional comments, and Charlotte Observer article below...

I'd like to own a gas station, and say "Gasoline, $2.00 a gallon, PLUS
TAX (to let people know how much the government gets).
If folks knew how much tax they paid, think they'd get a little upset?
(I'm sure thats why the politicos hide as much tax as they can).

Note: I'm not trying to "get one over on the government that provides
the roads" - I should "help pay" for the road. Not a problem.
Please don't carp about me trying to avoid "paying my fair share" - What
I don't want is for the evil succubus tax person to come after me 3
years hence, and decide I should pay $5k in taxes, and another $10k in
fines.

THOSE WHO MAKE THEIR OWN ENVIRONMENT-FRIENDLY GAS CAN AVOID PAIN AT THE
PUMP BUT NOT THE TAXES.
A price to pay for alternative fuels
BRUCE HENDERSON
[EMAIL PROTECTED]
Bob Teixeira re-applies a sticker touting an alternative fuel he uses
in his car. He plans to fight to change fuel-tax laws that have hit his
wallet.Bob Teixeira decided it was time to take a stand against U.S.
dependence on foreign oil.

So last fall the Charlotte musician and guitar instructor spent $1,200
to convert his 1981 diesel Mercedes to run on vegetable oil. He bought
soybean oil in 5-gallon jugs at Costco, spending about 30 percent more
than diesel would cost.

His reward, from a state that heavily promotes alternative fuels: a
$1,000 fine last month for not paying motor fuel taxes.

He's been told to expect another $1,000 fine from the federal
government.

And to legally use veggie oil, state officials told him, he would have
to first post a $2,500 bond.

Teixeira is one of a growing number of fuel-it-yourselfers -- backyard
brewers who recycle restaurant grease or make moonshine for their car
tanks. They do it to save money, reduce pollution or thumb their noses
at oil sheiks.

They're also caught in a web of little-known state laws that can stifle
energy independence.

State Sen. Stan Bingham, R-Davidson, is known around Raleigh for his
diesel Volkswagen fueled by used soybean oil. The car sports a "Goodbye,
OPEC" sign.

"If somebody was going to go to this much trouble to drive around in a
car that uses soybean oil, they ought to be exempt" from state taxes, he
said.

The N.C. Department of Revenue, which fined Teixeira, has asked
legislators to waive the $2,500 bond for small fuel users. The
department also told Teixeira, after the Observer asked about his case
this week, that it will compromise on his fine.

But officials say they'll keep pursuing taxes on all fuels used in
highway vehicles. With its 29.9-cent a gallon gas tax, the state
collects $1.2 billion each year to pay for road construction.

"With the high cost of fuel right now, the department does recognize
that a lot of people are looking for relief," said Reggie Little,
assistant director of the motor fuel taxes division. "We're not here to
hurt the small guy, we're just trying to make sure that the playing
field is level."

Use promoted, little regulation

State policies firmly endorse alternative fuels.In 2005 legislators
directed state agencies to replace 20 percent of their annual petroleum
use with alternatives by 2010. About 6,000 of the state's 8,500 vehicles
are equipped to use ethanol. The state fleet also includes about 135
gas-electric hybrids.

Few states, however, are prepared to regulate the new fuels, says the
National VegOil Board, which promotes vegetable oil fuel.

"State offices do not have the forms to appropriately and fairly deal
with VegOil, nor the staff to enforce the non-existent forms," said
director Cynthia Shelton. "So either they tell people inquiring about
compliance to get lost, or they make them jump through a bunch of
arbitrary hoops."

Outraged Illinois legislators this spring quickly waived that state's
$2,500 bond requirement when an elderly man was nabbed for using waste
vegetable oil.

In the mountain district of state Sen. John Snow, D-Cherokee,
home-brewed ethanol was once known as moonshine. But a couple of
constituents who made it for fuel have been fined for the same tax
violation that got Teixeira in trouble.

Snow has introduced several bills to promote biodiesel, which under
state law includes vegetable oil.

"One of the biggest problems in the state is a real lack of information
for people who want to use alternative fuels," said Snow's research
assistant, Jonathan Ducote. "It's just now appearing on (regulators')
radar."

Done in by bumper sticker

Teixeira's story began near Lowe's Motor Speedway on May 14. As
recreational vehicles streamed in for race week, revenue investigators
were checking fuel tanks of diesel RVs for illegal fuel.

The investigators quickly spotted Teixeira's passing bumper sticker:
"Powered by 100% vegetable oil."

"It was like some twist of fate that put me there," he said. "It was
like I was asking for them to stop me."

Teixeira says revenue officials are just doing their jobs. But he thinks
it's unfair that he was lumped with people who purposely try to avoid
fuel taxes.

"Individuals who are trying to do the right thing environmentally cannot
and should not continue to take this kind of financial hit," he wrote
Gov.
Mike Easley.

Teixeira says he'll pay the state fine and apply for a state fuel
license.
But pumping regular diesel again "broke my heart."

"I'm ready to get myself legal," he said, "and start using vegetable oil
again."

With a 4.11 rear end he's putting 772 lb-ft * 4.11 = 3173 lb-ft to the wheels
With a 3.73 rear end he's putting 772 lb-ft * 3.73 = 2880 lb-ft to the wheels

My Pinto will use a 3.25 ratio, I estimate that if I can see 1000 lb-ft * 3.25 
= 3250 lb-ft to the wheels.

If we only see 900 lb-ft * 3.25 still equals 2925 lb-ft to the wheels.

BTW, my new Dutchman rear end showed up yesterday, and the chunk with the 3.25

Hey dick did not your mother tell you not to play with strangers  and not to
piss people off you don't know..
.. Looks like you need spell check to ..
If it is that important to you.. I would also guess you don't know anything
about the question anyway.. Did it make you feel better to rip my spelling .
 Is that what it takes to make you feel good .. the fine English .language..

The thing we're probably not looking at enough is the whole picture.

Let's say 90% of my driving is 10 miles per day. No problem with a smallish battery pack.
9% is 30 miles of errands.  Probably no problem with a decent pack
1% is 160 miles.

First, I could stack in a bunch of batteries. My Jeep project is at 2000 lbs with a 4300 lb Gross weight. If I actually put in 2300 lbs of batteries, I'd get some range, but it would take more kW to move it. But in the other 99% of my driving, that added weight will use more electricity, every day. The production of that extra electricity is not totally clean. The production and eventual disposal of those extra batteries is not totally clean. I really don't think it's ecologically sound to design for significantly more range than you need most of the time (assuming a reasonable DOD).

I could keep a gasser around for 1% of my driving. The manufacturing and eventual scrapping of another car that will mostly sit and rot in my driveway is not without environmental impact.

I could rent a gasser for long trips. That might make some sense, but does a gasser really pollute less and consume less fuel than an EV and a good small generator? I think it depends on the range of the EV without the generator, and the length of the trip.

I could pull a small generator on a trailer for that 1% of the time I need it. Virtually no downside when I don't use it.

Something that hasn't come up yet in this iteration of the range
extender discussion is that if the genset is charging while you are
stopped at lights, etc., then you need to consider the acceptability of
the noise and vibration, etc. of the genset running possibly flat out
essentially the entire trip.

I'm thinking it'd be on a trailer, so vibration is no big deal. Some generators are noisy, but they don't have to be. That is a consideration. What concerns me is I'd like air cooled for reduced weight, but I think they tend to be noisier.

Unless you spend much of the time stopped
the genset is unlikely to put much charge into the batteries (a 2min
stop will only allow about 0.6Ah into the battery at 20A, and anytime
the vehicle is in motion the genset output will largely or entirely go
toward offsetting the load rather than charging the battery).

That was my intent, just augment the battery current while moving, which should also reduce the current draw on the batteries enough to significantly improve the number of kWh they can contribute. Do a little charging during stops and deceleration, and while parked at the destination if no opportunity outlet presents itself. As you pointed out, the amount of recharge gained during the duration of a stop light might not be worth the noise.

This is particularly a consideration if you are not willing to put the
genset on a trailer instead of in the vehicle somewhere (I seem to
recall the trailer option being noted as unacceptable).

Personally, I'd have it on a trailer, half the reason I'd do this is so that I could also use it either at the house or the shop (4 miles apart) for building power in case of a power failure, in which case I may not want to be the same place it is.

You also need to consider how you are going to connect the generator to
the battery.  Most gensets provide an AC output, and probably the
slickest way to adapt this to the battery pack is to put one of Rich's
PFC chargers between the two.  Set the current knob for the desired
amount of assistance and leave the voltage as for a normal charge.
Assuming a typical pack voltage in the ballpark of 120V, a PFC20 would
let you run the genset at a little over 50% output; a PFC50 (throttled
back) would let you run it flat out. (Many gensets aren't expected to be
run flat out for extended periods and will not last long used this way.)

Personally, I like the idea of using a considerably bigger generator than necessary, and keeping it 50% output or less. I'm thinking of maybe a small Honda or Subaru (lower aerodynamic profile) car motor loafing along at around 1800 RPM, with a belt drive running one of those Harbor Freight 10kW heads at 3600 RPM putting out around 5kW. Use the car computer for full emissions control, with a decent muffler on it. It ought to be quiet, and last forever. I haven't given a lot of thought to the actual charger yet.

The genset takes up space and payload in the EV, reducing the amount of
battery you can carry.  Depending on the distance you need to go, the
inherent range of the vehicle, and how much energy it consumes, a 5kW
genset might well get you there.  Only you can decide if the noise and
vibration that your otherwise silent EV gains from the onboard genset is
an acceptable compromise.

Agreed. For my use, I'd just use it occasionally to reduce dependance on a huge battery pack or a gasser for my somewhat longer drives. The rest of the time, I don't want to haul it. If I had an S10, I'd be tempted to put it on a palette and drop it in the bed, but in my Jeep project, no way. I still think if the intent is to drive all day, it makes no sense.

so you can't generalize. no biggie.
I think it's a bad design because it's a complicated way to make a gas car look like an EV

I think with the newer, thinner solar panels, a "popup" shade cover
would be cool, literally.

It gets to 113 for days on end around here, If someone could invent a
folding shade structure that has a solar roof, it could help
charge the car and keep it from getting roasted in the sun.

Hello Lee

I have been having a hard time myself finding a good AGM  for the factory 
Rangers.

Have had some fairly bad results with the new  low cost AGM Trojans in group 
24 and 31. I just returned 78 of them and another  person returned 26 of the 
group 31.
I also know of one capacity test on a yellow top group 31 that lasted 30  
minutes at 50 amps brand new off the shelf with a full charge. It should have  
lasted 75 or 80 minutes.

I had asked if anyone had any feedback on the  Odyssey batteries which is 
part of Hawker. No one responded but it looks like a  good battery but they are 
expensive a lot less than your Concords. I remember  looking at Concords and 
from what I read felt they were a well made battery. If  they lasted you 10 
years they must be good. How many miles did you get out of  them?  Your 
Concords 
is the 95 Ah rating a 20 C rate? 

Odyssey  claims theirs are military grade the PC 2150 has a 1C rate of 73 Ah 
the 20 hour  is 100 Ah.  
http://www.odysseyfactory.com/documents/US-ODY-31-003_1206.pdf

I am  curious what is the weight of the vehicle and how much are you 
budgeting for the  batteries?

Well, my almost  10-year-old pack of 12v 95ah Concorde AGMs is ready for 
retirement. Out of  the original 12, only 9 are left. I just lost #10 to 
an internal open). The  low remaining pack voltage, coupled with the 
remaining battery's already low  amphour capacity, gives me too little 
range to bother with them any  more.

So... I'm wondering what kind of batteries to try next. More  Concordes 
at $340 each? Optima D31's at $270 or so each? Go back to flooded  (even 
they are around $160 each)? Maybe a cheap set of Sam's Club specials  for 
$60 each (they won't last long, but the price is low).

Many  switch to an "exotic" battery? Thundersky lithiums (but where to 
get good  ones)? Nicads? Nimh?

I'm open to suggestions! :-)

Hey Phelps, that was the one guy you would really want to answer your question, 
although you probably wouldn't know it.  And he
wasn't speaking English, that was jivanese, (thats what DC motorheads speak 
after a hard day of wrapping windings).  What he meant
was that its really exciting working on a new conversion, and was making a 
funny about it being too overwhelming to operate a
camera being so excited (he was only speaking from experience of drinking 36 
cups of coffee for breakfast and tearing into peoples
brand new motors ;-)  Just send him some pics of the thing, I'll be surprised 
if he hasn't seen one.

Plenty of examples of people using them at higher
voltages.  Keep your RPM's limited to 5000 an you'll
be fine (unless you get a lemon to begin with, lol)

One thing to note that I've found.  On new motors, ADC
uses (at least the few I've seen) a flat brush and it
is not seated.  This is why all the old timers ran
their motors in. I doubted all their seating in talk
of flat brushes as I had never seen a non-pre-seated
brush before.  When I order replacement brushes they
come pre-seated or curved to basic commutator curve. 
Kind of fun to find the answer to why we're all
looking at each other like we're crazy, and don't
think the other knowwhat the heck their talking about,
truth is there are two different brushes one for new
motors and one for resale.

Next, make sure it's set so the brush timing is
correct for your rotation and it should be timed for a
CCDE rotation when received.

One last thing, you might want to test all the brush
and lead screw connections (just don't stab the comm
with the screwdriver).  I found a lead connection on
one of Lawless' ADC9's and it was two full turns loose
which would have caused a warranty at even lower
voltages but could still be used against you if this
were to happen.

To be really thorough after blocking the motor bench
test it under "12 volts" and run it to make sure she
arrived safely with no shipping damage.  Issues are
not the norm, ADC makes a good motor, just some things
to be aware of so to speak.

If nothing else tame yourself from John Wayland like
"desires" to pound down the amp peddle to see what
she'll do, until you've put some miles on it and
developed some comm film as well as seating in the
brushes.

Anyway just thought I'd put my two cents in.
Hope this helps

Is it a JH-29 used by www.e-volks.com? If so they run
it up to 96 volts with heavy duty air blowing through
it. I plan on using one in a Honda CRF. Have it
already. Just need to build an adapter, get a
controller, batteries and wiring. Got a bit to go.
Plan on using an AXE-7245 72 volts 450 amps.

Unless they have drastically chaged the way the prius works, This is not
accurate.

A 4 gear planatery gears set called the power split device is
sandwitched between two motors labeled MG1 and MG2. All togather in the
space of a tranny and submersed in oil. The mechanical resistance of one
of the MG,m used as a generator, is used to vary the effective ratio in
this planatary gearset. It can't even go reverse without the electric
motor.

Dan,
 
Did it ever occur to you that almost every reply you receive
starts with "NO", after you make a statement?

In case you want to alter this, I suggest that you read up
on a subject before commenting, because it tells a lot
about a person when he is continuously corrected for making
false statements. Let me make it obvious: Nobody believes you
if all the long time senior members either do not take the
effort to reply to your posts (because you have shown an
attitude that you do not want to learn from the info on this list)
and others are constantly correcting the wrong data you are
spreading.

Now a very honest question:
Why are you on this list?

Are you trying to learn? Your attitude says no.
Are you trying to share knowledge? The corrections tell otherwise.
Are you trying to share your attitude? This list only exists by
enough people not having one that gets in the way all the time.

Many people on this list have studied the Prius intricate workings
and the genius construction in many unique new techniques, leading
to it being the highest mileage car that you can buy today in the
USA and it has sold almost a million units already.
So, your statement "why bother, it is just another plain ICE"
shows a total lack of what the Prius has established and how
it is a great way to make everyone aware of how electric drive
works well in a car, even though it is currently fully fueled
from gasoline. 

Now, if your intention on this list is to stir as much as
possible controversy, then I think you are doing a wonderful job.
People like that are usually quickly recognised and categorised
as troll, after which everyone, except the inexperienced, will
ignore the troll.

Where do you stand?

aside from the fact that the end result is an expensive ICE car and not an
EV. it's effectively an electric clutch. the design will not survive and
should never have been. if one was conspiratorially inclined (and one is)
one might be suspicious that they intentionally chose a bad design because
it could give the illusion of being environmentally friendly while still
remaining a pure ICE car.

high voltage does appear to be the key. amps are bad

--- Begin Message --- I have the 1000th cycle just coming up with LFP-30 cell on tester. The 160 ah cell you're referring must be LFP one.

I will put plots to net with details as soon as it reaches 1000th. It was well over 800 cycles (100% DOD) week ago. I plan to cycle it as long as it fails completely. Every cycel as much as can be taken. 1C cycles.

So far I can say that from 400 to 800 cycles the capacity reduction is about 3 % with 100% DOD cycles. this cell had already originally only about 27 Ah or so.

Internal resistance seemed to be in ok level for EV use. But more as soon as I have it written and on the net.

-Jukka

p.s.- I'm currently sitting in our office in TS factory (Shenzhen, China). Any other questions guys ?

You must be referring to Thunder Sky batteries? Has anyone actually cycle

The 160Ah cells I referred to were ThunderSky, yeah, though there are a few other manufacturers around the same $0.50/Wh price point (e.g Liteway, Huanyu). All the cheap ones are Chinese of course, which might be a bit of a concern!

I haven't come across any independent cycle life tests for them yet, no. Maybe I should set up a test rig doing 1C cycles and see how they go. Hmm at ~12 cycles per day, it'd 6 months non-stop to reach 2K cycles! Guess I'd better get started ;)

The question that should be asked of Dave is how much does he have to budget
for this? Ian Do you have a link for the BMS?

A couple of suitable BMSs:

35 miles is a long commute! My sympathies  :)

While I don't disagree with charging at work being a good idea  to
reduce battery requirements, I think you could a 90 mile range  with
about $10K worth of lithium..

Going with ~200 Wh/mile for  a small car like a Fiero or Del Sol,
let's say you need a 20kWh  pack.

With lead acid, that'd be something like 25 Trojan T105s, which  would
weigh over 1500 pounds - obviously not feasible in a small  sports
car! And you wouldn't be able to get 200Wh/mile, that's for  sure.

With lithiums, as an example you could use 40x 3.2V 160Ah  LiFePO4
cells, which would come in under 500 pounds, and would cost  ~US$10700
including freight. Might not be out of the  question.

$30-50K is possibly what it'd cost if you used Valence  batteries..
(But why would you!? ;)

Hello Dave

 Your best plan would be to work on your employer to allow charging
at work.
Your required 35 miles is going to be hard enough to  achieve with
lead acid.
You  will have to spend  between 30 and 50 thousand for the
batteries alone to
 go  70 to 90 miles. It also sounds like you are going to want AC?
You could
figure a  10 or 15% deduction when running that.  Or as others has
posted use a
cooler with  ice or  some other way without adding added drain on
the  pack.

Low cost new technology batteries are not here  yet.
