I say "both."
Connect them in two strings, and parallel the strings. Then, add small-
gauge wires, possibly fused, to "buddy pair" the equivalent batteries in the
strings. This allows the advantages of buddy-pairing, such as lower battery
regulator count (if you use them), and improves charge balance between the
strings.
However, if one battery gets a bad cell, the small-diameter wire paralleling
it with another one in the other string warns you of the problem because it
gets warm or hot, or blows the fuse (check them periodically).
Without the cross-wires, should one of the batteries develop a weak cell,
the higher voltage string will constantly discharge itself into the other,
running itself down and overcharging the lower voltage string's good
batteries.

Alan,
I suggest you see http://geocities.com/evcharging and I that
you look at some factors local to your part of Georgia.
Twist lock connectors like L6-30 should never be used. If
the vehicle moves (earthquake in CA, or driver forgets to
unplug, etc.), the twist lock stays and the ripped apart
live wires tangle.
Straight blade connectors like the 5-20, and the 14-50 can
be used. But some hosts would be liability concerned of
the 14-50 (208VAC).
A standard 120VAC 20amp built in gfi duplex receptacle
should be part of any public EV charging installation, for
nEVs and conversions to use.
But there are few production EVs available that can charge
on a level 1, 1kw 120VAC 20amp 5-20 outlet. So, a level 2
6kw source will need to be provided.
Installing a regular 14-50 and 5-20 would be the easiest and
least costly. This would similar to using the power at an RV
park. But because of the fore mentioned liability concerns, a
charging head is installed instead of a 14-50 40amp outlet.
Installing a 5-20 and an AVCON would provide power to all
EVS (inductive EVs would carry their charger and AVCON
adaptor).
An AVCON powerpak charging head (link on the above site) is
currently priced about $400. The TAL (small paddle
inductive) costs over $2000. By the way, the TAL's small
paddle work fine with large paddle EVs.
If done correctly the correct charging is installed in a
contiguous route without wasting installation funds on
equipment that isn't needed. I would find out how far
away is the nearest TAL and AVCON charging heads are.
LA has way too many EV charging spots, too close
together. In Hollywood, some are across the street
from each other (a big waste of EV installation fund$).
EV charging locations should be in a contiguous route,
the locations should have 24 hour access, and hopefully
there is something to do where there. The SF Costco
only allows access during their business hours. This
is not good for traveling EV drivers (how are they to
know the hours. Worse they show up and are locked out).
RAV4 EVs with their easy 90 mile range, only need a TAL
charging head every 80 miles. So installing a TAL at
every EV charging spot is not needed, and would be a
waste of EV charging installation funds.
AVCON users (Rangers, Think Citys, and EVs that adapt to the
AVCON) have a range from 50 to 35 miles. So, AVCON charging
heads should be located every 30 miles for maximum access.
Scenarios:
-Host is liability concerned, there is already TAL chargers
80 miles apart, and the host will provide only one parking
spot near a wall.
Then install an AVCON powerpak and a 5-20 on the wall. The
EV parking sign is mounted at a 5 foot height, and the
charger and outlet is just below the sign. A front wheel
cement block is installed 5 feet from the charger. (this
will put the sign in the driver's face, and the block keeps
the huge SUVs from smashing the charging head).
-The host is liability concerned, there is no TAL chargers
that meet the 80 mile range, and the host will provide
three parking spots together in the back of the parkig
lot.
Then install an AVCON powerpak on one pole in front of the
right parking spot. And a TAL charging head with a 5-20
below it on another pole in front of the left parking spot.
Each pole is 6 ft tall (2 feet in the ground) with the EV
parking sign is mounted at a 5 foot height, and the charger
and outlet is just below the sign. A front wheel cement
block is installed 5 feet in front of each charger. Each
spot's lines are paint green, and the middle spot is
diagonally marked with green lines to show the three spots
are connected.
-The host want to go for the lowest cost, is not concerned
liability, there is already TAL chargers 80 miles apart, and
the host will provide only one parking spot in the rear
near the power panel. The location was not marked
previously as a parking spot, and the space will be
parallel with the wall. The spot will not be used by
delivery trucks.
Then install an AVCON powerpak and a 5-20 on the wall. The
EV parking sign is mounted at a 5 foot height, and the
charger and outlet is just below the sign. The spot will
have green painted lines to denote a special spot.
If you have any other EV charging questions let me know.

Back when my Civic EV was still equipped with 12 volt Delphi batteries from
an EV1, I contacted an EV1 dealer in California about replacements. I was
quoted $768 each for the Panasonic replacement units. Obviously, I didn't
buy them. 26 would have cost me $20,000.

Yeah, certified. Before Toyota will even release your car you have to have
the charger installed, with proper permits from Building and Safety. If you
or you electrician install it, a subcontractor from Clean Fuel (Toyota's
charger contractor/installer) has to come and fondle your leads, say
something like, "Mmmm, hmm...mmm hmm...looks good to me", sign the paperwork
and you are thereby CERTIFIED by Clean Fuel/Toyota. (Is this a good
thing?...)
But where's m'damn car?!?
By the way- from my experience, Toyota is NOT trying very hard to sell this
car. Many, MANY hoops to jump through. At the same time they're practically
giving their ICE vehicles away (rebates, 0% financing, etc.)

I actually received a description of the posts for the Evercel MB80, along
with a picture of the battery. It looks like all intercell connections are
accessible!
The terminal post is an 11 mm threaded stud with a 6mm thread in the center.
The stud gets epoxied almost flush with the top.An intercell connected is
secured from cell to cell with the 6mm screw.
I can email the picture to anyone who asks, I just don't have access to FTP
right now, so I can't put it up on my site.

In general, new cars are all getting quieter. EVs are just on the quiet
side of normal. People will have to get used to quieter cars no matter
what.
EVs are quieter than the average car; but they are not quieter than the
quietest gasoline cars already being sold. Mainly, it's because the
quietest luxury cars have enormous amounts of padding, muffling, sound
absorbers, etc. to make them quiet. Most EVs do not have all this sound
deadening material (to save weight).
As for urban noise pollution, this is determined mainly by the noisiest
vehicles, not the quietest ones. A single loud truck, motorcycle, or car
will drown out a thousand regular cars. Who has not been disturbed when
trying to fall asleep by just one ultra-loud motorcycle, sports car, or
worn-out wreck with a bad muffler being raced through the deserted
streets at 2am?

John,
I see what you mean about tight battery boxes. Awkwardly shaped, too!
Don't feel too bad about the wiring mess. It always sounds easy to run
"just a few wires" to each battery. And it always develops into a
tangled mess. (Been there, done that! :-)
However, one thing to watch out for; you've got full pack voltage
between these various wires. For your 156vdc system, you want to wire it
as if you would be connecting it to the 120vac line (which peaks at
170v).
Things like normal automotive wire, speaker wire, telephone wire etc. do
not have sufficient insulation. If there is no UL (or equivalent safety
agency) marking on the wire, it usually means it has never been tested
for insulation voltage breakdown, temperature limits, abrasion
resistance, flammability, etc.
Some of your comments worried me (telephone wire, LEDs just held by the
leads). The LED wiring is a significant shock hazard, and if a short
occurs, the wiring could catch fire before a fuse in the Rudman
Regulators blows. Since almost everything around these wires burns, you
could have a serious fire if something goes wrong.

How do you figure that is a better use of their money?
The Think is almost ready for mass production with only a few bugs to be
worked out (if they haven't already).
It has been designed for mass production and I believe it's already
completed federal testing (could be wrong here).
The Tango is an impressive vehicle but it is still basically a concept car.
It hasn't been designed to be economically mass produced.
Unless they are willing to sell-out(doubtfull) on some of the Tango's best
features (like the full roll cage) the Tango will cost 3-4 times as much to
produce as the Think(possibly even more).
This means the final vehicle will cost 4 times as much, or more. This will
cost you the vast majority of your potential market.
The Think is a low end EV which fits well with ZAP's apparent philosophy
(ZAP bikes are definitely low end). The Tango is a high-end EV which would
probably cost as much produce as the EV-1 and will likely sell for a similar
price (current price for the Tango is about twice the hypothetical price of
the first generation EV-1)

A) All the MKII's have 2A fuses. Any short in the LED wiring will blow the
fuse before the wire overheats. (If the Green LED line gets opened, the
fuse also blows.) The LED leads are coated with silicon caulk pretty thickly.
B) My use of standard 4 conductor phone wire, there are no conductors in a
bundle with over 24v between them. Any higher differentials have to pass
through 2 wire walls, and 2 4cond jackets. If any of these wires ever
shorts, the wire is small enough to vaporize pretty much instantly. Being
hot enough, long enough, to light something on fire is pretty unlikely.

[Warning, this post is likely to light John's fuse]
We have both a Toyota Prius and my Renault LeCar EV. The Prius is
absolutely silent when in "stealth" mode (i.e. when the gasoline engine
is off). We really do have to watch very carefully in parking lots when
starting off. People are accustomed to hearing the engine idle as a hint
that a car may move. With no engine noise, they will walk or stand right
in front of the car.
My LeCar EV has a Curtis 1231C controller. This model produces a faint
"eeeee" when you first start out at low current. It is such an unusual
noise for a car to make that people will look around, see the car move,
and then get out of the way. So, I actually like this sound -- I
consider it as my "pedestrian alert."

A good practice is to use your lights, even in the day. Most people
respond to visual cues in a parking lot, as well as to the noise.
Turning your lights on before moving tells most people what you're up
to. If you are worried about the extra current draw, you can shut
the lights off again when you are underway.

I had a "lack of noise issue" with my EV one time.
I was pulling into a parking space and the fellow who had just parked swung
his door open as I was pulling into the space next to him. I stopped the car
just in time. He was very apologetic and said he didn't hear the car coming.
Of course he should have looked before opening the door but it shows that
people have been conditioned to listen to ICEs running around and people use
the noise as a cue when they are taking in their surroundings.
Also in our neighborhood there are tons of kids running around. I've found
myself behind kids playing in the street who are completely oblivious to the
EV approaching. They maybe completely oblivious to gas cars as well. I use
my horn quite often in the neighborhood.
But some people do have a point about some of the newer gas cars being
quiet.

My neighborhood has had a crime wave, so I have been doing mobile
neighborhood watch, patrolling my neighborhood from 2 to 4 a.m. once
a week.
I was thinking how cool it would be to do this someday in my EV
conversion. I could cruise around in total silence, maybe even catch
some of the bad guys in the act...
I was trying to use my Jeep more, as it is pretty quiet, but have
evolved to using the 300 horsepower, 100+ dB Camaro! An algorithm has
evolved: less than 2000 rpm, neighbors rest assured; 3000 to 5000 rpm
full throttle, time to look at the windows and see what is going on!
One night we had 15 people and 5 cars surrounding the perps by the
time the police showed up -- many came out because of the roaring
exhaust.
What I'm thinking would be fun (probably won't get around to doing)
is to have a sound card play an engine sound, frequency proportional
to engine rpm, volume as a function of amps, and maybe some waveform
clipping as a function of temperature. Then I could fight noise, or
fight crime, with the twist of a knob.

I'm glad to hear someone else say this. I've always liked the Curtis whine. It sounds
different than an ICE vehicle and people notice. My Tropcia has a whine although I
believe it's the belts not the controllers. I like it. My daughter says is sounds like
Rocket Rods in Disneyland. Lets hope the Tropcia is more reliable ;) I have to admit
I'm guilty of hitting the throttle a bit when I pass people just attract attention. I
do have to watch when backing out of parking spaces however. At a crawl it doesn't
make any sound and I have had people startled seeing it move. I don't see it as a
problem. A noisy car is not a substitute for paying attention while driving.

I would consider the Dodge TEVan the 'Harley Davidson' of EV's.
The 4khz PWM frequency (2khz during regen) is so load that people actually
turn
their heads to see the 'spaceship' landing.
If I'm not loudly PWMing the motor, the battery box fans, controller/motor
fans are
so load it definitely gets people to notice something strange is coming
their way.
Most people look to confirm a car is coming their way, when I pass people
look
to see what passed them.
No beepers/chimes or reverse alarms required.....

hmmm....not surprising that REVA will be available in the UK from next year. I heard a
few cars have already been sent
to UK to elaborate testing. Should be interesting to see the results of the tests!!

City spends £60,000 on 'dead duck' cars
By SAM HALSTEAD
TRANSPORT chiefs are to spend £60,000 testing an electric
car in Edinburgh despite motor giants Ford pulling the plug
on the "green" vehicle.
Trials of the battery-powered Th!nk car are set to continue
in the Capital for nearly three years even though Ford has
abandoned the technology.
Critics today urged the city council to ditch the "dead
duck" car which will now never be produced on a mass scale.
But city transport chief Andrew Burns defended the trials as
worthwhile, insisting they would still provide valuable
lessons about how green technology could be used to help
clean up the Capital.
Ford, the world?s second-largest car manufacturer, recently
abandoned production of the Th!nk car after selling just
1000 vehicles worldwide.
Today, Councillor Allan Jackson, the city?s Tory transport
spokesman, said: "What is the point of throwing £60,000 at
something which has been abandoned? There are better ways to
spend £60,000. This is a dead duck. I think this is
ridiculous when production has stopped and the car factory
is for sale. This is an irresponsible use of taxpayers?
money."
The Capital was chosen along with London and European
centres such as Amsterdam and Rome to carry out trials of
the two-seater vehicles.
Edinburgh City Council was one of nine groups which agreed
to lease a total of ten cars in the city as part of the
trials which began in April. The Caledonian Brewery and the
Royal Bank of Scotland were among the other organisations to
support the scheme.
But in August, Ford announced it had ditched the car, and
instead had turned its attention to developing alternative
green motoring technology, including hybrid petrol-electric
vehicles and fuel cell cars.
Today the city?s transport leader, Councillor Andrew Burns,
said: "This is not a waste of money. Ford has decided to
focus on low-emission cars, hybrids which will use battery
and fuel-powered cells. These trials of the technology are
not going to be for nothing. The same technology will still
be used in the hybrid car.
"The question is: ?Do the Tories think low-emission cars are
not the answer??. We have taken a pragmatic approach. The
same technology will be used, but in a different body
shell."
A spokesman for Ford said today that the Th!nk ultimately
failed because it could not travel long distances, there was
not a short enough recharge time and there were not enough
recharge outlets established.
Now the company has decided to focus on developing fuel cell
and hybrid petrol-electric vehicles.
"We made the decision to invest in different technology. The
Th!nk was not the future of environmentally-friendly
motoring," said the spokesman.
The continuing trials won the support of the city?s Liberal
Democrats. Edinburgh?s Lib Dem transport spokesman
Councillor Fred Mackintosh said: "I think the trial should
be continued. £60,000 could fill a lot of potholes, but I
think we need to be a bit adventurous."
A spokesman for the Th!nk scheme said feedback from all ten
city-based groups involved had been very positive. He added:
"It is such a great car, very economical and easy to use."

When I was using Windows, and on my wife's Windows computer, I use(d)
McAffee. It can be set to scan incoming email. Works real good with
Outlook, and it can be set to automatically update its virus definition
files. Never had a complaint - or virus.

I use Norton Antivirus from McAffee. It will automatically update your
virus definitions, and regularly warns me of viral messages that come up on
the list. I have been "healthy" for a long time.
Next time Norton warns me I will send along the message, usually I just
delete the email.
