That's a good question :)
I haven't explored the details, however an old mercedes fanatic says
this about it:
"This four-door model is constructed on the same advanced monocoque
body/chassis unit as the other 190 Class models"

What type of "frame" does it have? Does it have separate front and
rear sub frames or a "full frame" type sub frame design?

Yeah, victor - I agree on the gun issue, but not on the lights!!!!! There
are some out there (not all of them on SUV's, either - most of them that
bother me are on smaller cars!) that ought to be banned!
Whether they ar xenon or not, I don't know - all I know is they are
dangerous to oncoming drivers. And that is NOT just my opinion!

Sorry guys, INHO you are wrong, very wrong. But it's just MHO.
No one will argue that better lit road is worse than worse lit one.
Brighter your light - better you can see.
IF light is adjusted properly, you can't be blinded by it,
xenon or not. If it's high sitting SUV, light must be pointing
steeper down to illuminate *identical*, standard per DOT stretch
of a road. If these SUV's owners don't five a damn about anyone
else and maintain their light's alignment it's not xenon's
technology problem. Hate the guy, not his lights.
May be you also don't like engineers who designed it?
A gun has never killed anyone. It's always a person, you know.

Subject: RE: LED headlight bulbs?
Michael,
You might consider HID (High Intensity Discharge) headlamp bulb
replacement
kits (AKA 'Xenon'). They cut the power used by the headlights in half
and
produce a much better (brighter and more suited to human eyes) lighting
effect.
Who says that??!!! I HATE them, because they half-blind me! Maybe they
are
just mis-aligned, but I wish they would be BANNED!
Right on, Joe!! I don't understand WHY they aren't. Usually on a
obnoxious SUV, rides 3 feet off your bumper 20 MORE over the speed limit.
Godamn lights are SO high that they blast your mirror to the point you
twist
it away!
Maybe a Landing light setup YOU could turn on? Locomotive headlights?
to
BLAST the guy back a bit? Except YOU are making a road hazard WORSE!
These
guyz are enough of a hazard when they CAN see! The'll be diddling with
their
radio, talking on the cell fone, reading a book/paper! I have scene this!
So to put these lights on YOUR vehicle you only make it worse out
there.
Hell! You don't go that fast you need them, in an EV!

Yeah this from the guys drooling over a drag racer or funny car that
would never be street legal, much less wise to jump into and try drive
long distances.
Seriously, who comes up to a drag racer and say "that only holds what, a
gal of gas? I can't drive between towns on that. And it runs on
nitromethane? How is that better than gasoline? It's way more
expensive. There's no room for my wife and kids or a trunk. Who would
ever drive this?"

I'm a car guy. I like all kinds, even unpopular ones and just because
someone owns a car I hate, I don't demean it, or them.
Yesterday, I went to a local car club's weekly meet/hangout yesterday
in my EV Beetle, not to preach the gosspel of EV, but just to look
around and see if anyone had anything new or cool. The hostility I
received was beyond belief. One guy told me my car was a "rolling
memorial to Adolf Hitler". I explained what drivetrain was under the
skin and why I chose it and everyone else pretty much agreed that it
was a useless idea because you can't jump in and drive for an
unlimited number of miles.
I went down there to look around and perhaps tap into the group's
knowlege on how I could improve my car figuring that just because a
guy has a 550 cu. in. engine doesn't mean he's closed minded and
won't have any ideas. I guess I was wrong. If this is the prevelant
attitude, we're in deep trouble.
If anyone needs me, I'll be looking for jobs and a place to live in

Hello all... I'm looking at a simple float charger
from HarborFright,
http://www.harborfreight.com/manuals/42000-42999/42292.PDF
I'm using a 72vdc, 10amp charger to charge my battery
pack, but am thinking that this float charger might
work for (balancing)topping off each battery in the
pack after an initial recharge. I'd install one on
each 12vdc cell in the pack. They are supposed to shut
off once the battery reaches a safe float charge.
These things are always on sale for less than $10,
right now, I think the website has them for $7.49.
Thanks in advance for your own humble opinion...

I think the problem comes from confusing "brightness" with "illumination".
Headlights are supposed to illuminate the road ahead, so you can see. So
years ago, they wrote the standards to require a certain amount of
illumination. Illumination is measured in lumens or candlepower.
A smaller, secondary purpose of headlights is so you can be seen by
others. This requires a certain brightness, measured in candelas. But
they did *not* specify brightness. Why not? Because there was exactly
one technology being used for headlights -- ordinary tungsten bulbs.
Their illumination-to-brightness relationship is fixed; if you specify
the illumination (lumens), the brightness will automatically be correct.
But now, we have many new light sources. Fluorescents have a much
*lower* brightness for a given number of lumens -- they would work fine
for you to see, but others would have trouble seeing you. Halogen lamps
have a *higher* brightness for a given number of lumens. LEDs and HIDs
(arc lamps) have a *much higher* brightness for a given number of lumens.
They haven't changed the standards to specify brightness. So, we have
headlights that technically meet the existing illumination standards,
but are *way* over the line on brightness.
Excessive brightness of your own headlights doesn't bother you. It
doesn't even let you see any better. But it causes blinding glare in the
eyes of oncoming drivers, making it harder for them to see.

Looks like a rebranded Meanwell SP-320/SP-500. The 13.5V model can be
tweaked from 12-15V. 120-370VDC input with output derating required below
~200VDC. Only 75% output at its rated minimum input of 123VDC. I'd wager
this would be a real stinker below 120VDC.
The 300W model would be good for ~16A with a 144V-156V pack, 21A with
190V input.
With a higher voltage pack it's definitely in the inexpensive/cheap
category. Keep it dry... The 270,000 hour MTBF ain't bad, and you could
blow up quite a few before you hit $1,500 for an "EV DC/DC".

Crikey! Sorry I suggested it in the first place.
Personally, I think Victor has the right angle on this subject.
However, I would go one step further and suggest that the reason glare from
headlights (of all types) has become such an annoyance is that nowadays, so
many vehicles have the option, built-in, to adjust the angle of their
headlamps at the flick of a switch. So if your vehicle is heavily loaded
(esp. in the back, which causes the lamp beam angle to rise) you can lower
the beams so they don't cause dazzle to the road-user(s) in front.
The problem is, of course, people being people, they either can't be
bothered to adjust their beams, don't know about it in the first place or
don't know where the switch is (rentals?).
I use, as a rule of thumb, that your dipped beams shouldn't get over the top
of the boot lid of the vehicle in front. That way it should not be possible
for your head lights to cause problems.
What's the answer? Self levelling lamps. I gather they are out there but
as ever, it will be a while before they become mainstream let alone
standard.
Last point - in the UK causing unnecessary dazzle or glare from your lamps
(front or rear) is a specific traffic offence. Unfortunately the Gov has
been paring down the number of traffic police to point of being extinct. The
local police are far to busy dealing with domestic incidents and such to
bother with enforcing any but the most serious traffic legislation. As a
consequence, it has been estimated that up to 20% of drivers in some parts
of London are uninsured and have no drivers licence!

I am the friend that Ed is talking about and I have had very positive
response to my 1991 Dakota. Everywhere I go people notice that it is
electric and they stop me and ask a lot of question. I always take the time
to answer their questions and let them get a good look at the truck. Last
Sunday, my wife and I felt like taking a drive to get some ice cream so we
jumped into the Dakota and went just over the state line into South Carolina
to a small hamburger stand where they serve ice cream too. When we came out
of the business with our ice cream a guy was looking at the truck. He
looked at me and said"you really do drive this truck everywhere don't you."
He then went on to say that he had been at the car show and saw the truck
but he did not think that I was actually driving it. I try to drive the
truck everywhere I can to show people that it is very possible to build and
drive an electric vehicle. You have to be ready for all opinions and other
points of views. I try to be open minded when I talk to other people about
my truck but I am very proud of it as Ed will attest to. The Dakota will
not break any speed records nor will it go a hundred miles on a charge, yet.
But it is an electric truck that does not have to use gas at all. That is
what I had intended to do when I started out to build the truck. So just
grin and bear it. I agree with some of the comments earlier about waiting
until the price of gas goes up so high they are unable to drive their big
gas guzzlers. Our time will come and I am willing to wait until then.

I'm a green conservative, and no, its not an oxymoron!

I agree with Lawrence; you'll find crazies no matter where you go, you don't

It sounds to me like you were confronted with dislike on 2 angles:
1 from having a "German" car, and another for having an electric - neither
of which is valid -
A friend and I took his newly converted 1991 Dodge Dakota to a car-show in
Monroe, NC.
His was the only street vehicle there that was electric; I'm obviously not
counting the "ez-go" vehicles that were there.
There was a great deal of positive interest, and while I walked away to look
at the other cars occasionally,
I don't recall even a single deragatory comment about my friend's truck -
and we're in "Conseravtive South" (not that near-by Charlotte is that
conservative).
My recommendation? Ignore those folks, and keep NOT burning oil, and keep
NOT funding terrorists!
Also, be encouraged by the work that Tesla and Phoenix Motorcars are doing.
May 2007 issues of Popular Mechanics, Popular Science, Car and Driver
magazines (and one other) all had positive articles about electric (and
plugin-hybrid) vehicles.
The Car and Driver magazine article was about racing; it even had pictures
of Gone Postal and others there; the other articles were about electric (but
mostly about hybrid) vehicles.
Its going to happen. Just keep your chin up, and ignore the idiots.

I've seen this on cars in Europe. However, I've never seen it in a car in
the US. As much as we are gadget geeks over here, the only reason I can
think of for there absence is that it's not legal.

Actually the real question is what they will do when gas
costs over $10 per gallon.
As long as it is 'only' $4 (will be this summer) or $5 per gal
(I am quite sure we will be used to that before summer 08 ends)
then people can still manage by shaving a little off their
unnecessary trips, spend a bit more of the household budget
on gas - but see it go over $10 (I expect we will get close
to that in the summer of 2010) and many will no longer be
able to afford their commute when they drive 70 miles or more
each way in a 14 MPG vehicle (numbers from just one of my
colleages, who recently found out that offered Prius with
carpool lane stickers have $4000 higher value than without
in California; he also finds that every Prius he calls after
is already sold before he picks up the phone to inquire.)
Since his commute consumes now 10 gallons/day, he pays
$680 per month for gas to commute. ($3.25 per gal regular gas)
so 'only' a few days each month his work goes towards paying
for gas. Once it hits $10/gal he will be working half his time
just to pay for the gas to commute... That won't last long.
But that means that a lot of people can't afford their homes
and distance to work any more.
So a large-scale change in housing is required (living closer
to work).
Even if battery technology would not be progressing at all in
the few years it will take to get to this point, then the
choice between $1 per mile in gas cost or $0.03 per mile in
electricity ($0.12 with battery depreciation) will not be
a hard choice at all.
BTW, if you feel like a good discussion and you encounter a
"Patriot" in a gas guzzler, then you can tell him that even
though he may have love for his country, his car is killing
that country, because just as much as he is buying gas, that
money is leaving the USA to buy oil, so he is draining our
economy.
With an EV you have no part in this if you run on renewable
energy; even when running on dirty electricity the majority
of your money stays in the USA.
But only do this if you like a fight.... Denial is not only
a river in Egypt and a variant of GMC Yuck-on but also a
very strong emotion.
By not pushing and preaching, but simply arriving at work
in an EV (when I don't bike or use other transport) my
collegues start to get used to the fact that an electric
truck is a viable way of transport and they are becoming
interested in EVs. Of course I will occasionally mention
it or explain about it when asked, but I try not to push
the subject too much, so they see my witness from my
actions.
Rising gas prices do the rest.
Hang in there - a little while and you will have quite
different experiences! I already sense more and more
colleages getting envious of my efficient vehicles.
(My Prius is my "gas guzzler").

We're screwed? No, they are screwed. We have adapted, they haven't.
Change is often not very forgiving, so I kind of pity them. How much is a
500 cube V-8 worth when gas hits $5.00 per gallon?
When I first met him, one of my co-workers had pretty much the same
perspective you encountered. I gave him a ride to lunch in my Solectria
Force and his reaction was "This does seem kind of practical". Then gas
jumped up to $3.00 a gallon. He traded in his
V8 for a 4 cylinder and got real curious about my electrics. He now
believes while they might not be for everyone, they probably are the right
choice for a lot of people.
Well, I am off to spread the "gospel" this evening to a group gathered to
see "Who Killed the Electric Car". I suspect I will have a more receptive
audience than you found.
Thanks,

Hey all,
This is only relevant because its about motors. I have water cooled my
computer, and now the weak link in my system is the pump. Yes I could
buy one specifically for this application but im looking at atleast 40
bucks. What I want to do is make a brushless disk "pancake motor"
similar to a windmill generator. The disk would be make of plexi glass
inside a water tight plexi glass compartment. It would have n impeller
on it. The coils would actuallt be outside the water chamber so there
would be no holes or water tight bearings needed. I suppose this would
be an induction motor, which means it can only be run on AC right? Can a
brushless disk motor be run on DC?
Thanks,
Paul

*********START OF MEETING ANNOUNCEMENT***********
Topic: Annual EV Display and Ride-Along Rally
Date: Saturday, April 28, 2007
Time: 10 am to 4 pm.
Site: Diablo Valley College
321 Golf Club Road, Pleasant Hill, CA
Purpose: Earth Day and public display/education/rides
Visitors welcome, open to the public. Look for the
wind generator at the Alternative Energy Center, where
we will be meeting.
Our Annual East Bay Display and Ride-Along in Pleasant
Hill / Concord is at hand - spring time and Earthdays.
Hope we can have a healthy turnout, even with the
distance some of the EVs need to be brought to
participate. Prizes for those who can participate.
Great opportunity even to display your EV since the
focus is on educating the public rather than pushing
for ultimate range.
Great opportunity to expose the general public to the
virtues of EVs. We will be driving a circuit route
around the college, up and down hills, to demonstrate
the virtues of the EV. Those EVs which can carry
passengers provide wonderful opportunities to discuss
the EV mission to a captive audience.
We will have refreshments, so even if you cannot bring
your EV, we can have a great time discussing the
virtues of EVs and interact with students at the
Engineering Technology Alternative Energy program.
Due to distances for members to bring their EVs, we
are also planning other Display and Ride-Alongs
throughout the Summer, including a Fall event in the
San Leandro / Hayward area, based at Chabot College.
EV charging available at Sun Valley Mall (1 Avcon
conductive, 1 Magnacharger inductive) and conversion
standards (110vac and 220vac) will be available at the
Alternative Energy center at DVC.
See you there.

Hi Paul,
You'll need an inverter to run on DC for a brushless
motor.

Hi Lee,
I've run into a snag. I've got the scripts finished, but I can't upload
them to my server.
A while back, I got tired of all the hackers from China trying to hack
into my servers, so I set up a firewall to prevent logins from China.
Apparently the IP addresses here in Okinawa come from China and I can't
get through the firewall.
I've tried working around it, but no luck.
I appologize for not coming through on my offer. I'm kind of bummed about
this.
Do you have me down for some relay bare boards? Can I send you the cash
via PayPal, or would you prefer I have my wife mail you a check?
Cheers, Pete.

I am having a brain cramp trying to remember the way depth of discharge
works. Help me out here:
I have 8 volt batteries. I run a total of 16 batteries which in theory is
128 volts. We all know that each cell, fresh off the charger is about 2.45
volts. (at least according to my manufacturer's tech support) so 64 cells X
2.4v = 156.8 volts total which is what my Zivan is programmed for. So here's
my question:
Is the 80% DOD rule for 128 volts or 156 volts? Or is it perhaps the
"resting" voltage of around 150 volts once the battery has been off the
charger for a while? 80% of these 3 values would be: 102.4 volts, 124 volts,
and 120 volts. I'm trying to figure out when I'm on "empty". I've yet to
drive this car to the point where my Mark I "butt-o-meter" felt any
significant loss of performance. My longest drive has been 36 miles, 17 of
which was at highway speed. When I finally pulled in to the house, I was at
120 volts and was only then starting to notice some loss of pep.
Second issue:
I've had a couple of days now where the temps have hit the 80's. The Zivan
NG3 is mounted in one of the 2 allowable positions (horizontal) in the trunk
of my Beetle. I've found that now my 12 ga. extension cord is much warmer
and the charge time is much longer. Last night I just figured out that the
charger is recirculating air in the trunk until it gets hotter and hotter so
it's losing efficiency. I opened the trunk to take advantage of the cooler
night air. Do any of you Southerners have any strategies for coping with the
heat? I'm building an E-Beetle for my uncle in south Florida and I'll need a
solution for this as well as for my own car.
The motor and controller are getting pretty warm too due to a lack of air
flow when driving. The builder lived in Alaska where this isn't really a
problem. He sealed up the engine bay good and tight with a belly pan and a
rain guard to block the Beetle's rear engine vents to keep the
motor/controller dry. I already have a solution for that though. I'm going
to cut 3 small circular holes in the belly pan and install dryer vents to
scoop and exhaust air while driving. They have flaps so I can close them
during the rain and winter.
Thanks in advance for the help,
Rich A.

Rich,
I would be very careful about going to the 80% DOD mark. You
will go through your pack very fast by going there often. I would go to
the 50% mark so your pack will last longer. 80% only on an "as needed"
basis. It is my understanding that the DOD mark is from the max voltage
the battery presents so your 80% of 156. I could be wrong though.

The weight has always perplexed me as I always assumed they built it
using fiberglass to reduce weight. Considering the body and the
frame, of the two; which one weighs more? Any numbers on either?
I'm not sure of the weights, but many parts of the Corvette of that vintage
are quite heavy. Fiberglass was chosen to make those fantastic compound
curves that are difficult to stamp out of steel at low cost; but the glass
is very thick compared to racing applications. That's not a bad thing,
since it had to put up with the rough roads and abuse of '70s traffic and
parking. The frame is also a heavy ladder bar design. The luxury items
fitted to most Corvettes also weighed quite a bit, but you ended up with a
very solid feeling luxurious personal transportation device. The '57 T-Bird
was a similar concept.
I understand someone is building '57 T-Bird kits these days. That would
make a nice EV project too :)
