Hi,
You sound just like me 6 months ago.
I ended up buying a 1984 VW Rabbit
convertible that was converted using
an Electro Automotive kit in 1998.
The car wasn't working went I bought it,
but I wanted something that I could
fix up. The batteries were in pretty bad
shape, and there was a lot of corrosion
on the battery racks. I've just finished
re-finishing and painting the racks, and
my next project is to add heat to the
car. I also live in Silicon Valley where
the climate is mild, but I need a defogger
for safety reasons.
Given my experience so far, I'd say buying a
used conversion is a great idea. You will
get it a lot cheaper than doing a conversion
from scratch. If you go with a 914 or VW,
especially one with a "standard" conversion,
someone else has worked out most of the
bugs in the conversion for you.
Good luck,
....Ken

Subject: Advice on buying a used EV.
I am very new EV's but have been fascinated by them.
Recently I have played with charging batteries from a
generator coupled to a stationary bike.
I have driven couple of EV's in the past including
Corbin Sparrow, RAV4 EV and Porsche 914 EV.
Rather than starting to build from a kit,
I want to start by buying a converted EV.
I live in the Silicon Valley and commute alone
30miles each way (almost flat) with
good possibility of charging at work and home.
This means I need minimum of 45 miles of range.
I would like it to be minimum of two seats
and prefer a convertible. Besides being a commute vehicle
I would like it to be fun(peppy) to drive too.
After looking at several web sites,
I am leaning towards a Porsche 914 EV.
Here are some stats:
120V (15, 8V Golf Cart almost dead batteries), 9" ADC, C1221, E-meter etc.
Here are my questions to the experts on the list:
(1) Is this (914) the right choice given my requirements?
(2) What things to look for when I go down to take a test drive?
(3) How do I gauge the quality of conversion?
(4) How to estimate the range with new batteries ?
(5) Pointers on how much to pay would also be useful.
Thanks in advance,

John, do you think just paralleling NiZn pack with very low capacity
PbA (like cyclons) of the same voltage can prevent deep
voltage sags during accelerations? Sort of ultra caps approach.

I've considered this also, in fact tried to convince a friend of mine to try
this. I think that a hybrid pack like this has a possibility to exhibit
'best of both worlds' - cold weather performance and range of a NiZn battery
combined with acceleration and ability to belt out the amps of a lead acid.

Sounds like excellent requirements. I require a convertible too. I
believe it's better to target 60 miles range if you are driving 30.
Your batteries will last longer and you will have a better chance of
making it in the winter.

Here are my questions to the experts on the list:
(1) Is this (914) the right choice given my requirements?
I think yes, if you enjoy owning old cars. I do, but beware that it's
a 30 year old car.
(2) What things to look for when I go down to take a test drive?
Rust, quality and neatness of the conversion. Read this:
http://www.pelicanparts.com/914/How_to_buy_a_914.htm
(3) How do I gauge the quality of conversion?
Find an expert whom you trust to evaluate it.
(4) How to estimate the range with new batteries ?
Use http://www.geocities.com/hempev/EVCalculator.html
Range would be my concern with this. 914s can be very efficient yet
everyone except Clare Bell seems to build them without much concern
for range. Mine has 20 Optima batteries and yet only does 30 miles
range if I'm very careful. It gets about 240 watt hours per mile
light footed 60-65 mph. According to the EV calculator it should be
doing 55 miles range. The problem is I haven't focused on it. My rear
brakes drag (6 lbs of force total) rear camber is off, I have no air
dam yet, and my tires were chosen more for stick than efficiency.
Also I have dual motors belted together and a big heavy dragging
transmission with dino oil. I've been focusing on speed instead of
range.
I think that with proper tuning of the car, and using the high
capacity 8V batteries, you should have no trouble in the summer. I
don't know if it will be enough range when the batteries get cold,
though I suspect it will be.
(5) Pointers on how much to pay would also be useful.
That varies a lot with condition and quality of the conversion.

How do you recharge such a pack without separating PbA from NiZn
each time? Is it going to be a "compromise" profile?

Ya know, someone's going to have to try it to find out, I guess. I'm not sure which
way would
be the best, but I do have a seat of the pants feeling that it would be best to keep
the packs
isolated from each other until the peak current demands are needed. I feel this way,
because
the fully charged state of the small lead acid pack needs to be floated at around 13V
per
battery so that they can jam out BIG amps for the first few seconds easily, but if
they were
merely paralleled to the NiZN pack while the EV is rolling along, the booster pack
would be
pulled down to the NiZN's lower voltage per battery level. Better still, would be to
employ a
compact but powerful DC-DC converter that would take a bit of juice from the NiZN pack
to
keep the booster
pack at an even higher 'standby' voltage or 14.5V per battery.
I would think that Cyclons of a 10 ahr or better rating would work great, but anything
lower in
capacity (save for the now unavailable Bolder Cells) might sag too low. The 14 ahr SVR
batteries sag down too, but not that bad 'initially' right after they're freshly
charged, even
at 900 amp levels...several seconds later, they do sag way down to the 8V level at this
high of
a continual current. My idea is to have the booster pack only see this high of a
current demand
for a few seconds, because at least in my street EV, the 1200 amp current sucking only
lasts
about that long, because the tires either spin and the motor revs way up (current
falls),
or if
the tires bite, then the car lunges ahead and in a matter of seconds, it's going so
much
faster, that again, the motor is spooling up and the back EMF naturally rolls off that
huge
current draw. There are times, such as at 45 mph on the freeway behind a slower car,
that
jamming the 'GO' pedal makes the Raptor send 1000+ amps out, but even then, in about 5
seconds
or so, the car is hitting 70-75 mph and the current is rolling back due to higher motor
rpms. I
think that in this latter case, it would be possible to exceed the pack stiffening
capacity of
even a 14 ahr pack, but the best way to find out, is to try it.
It might be cool to devise a main pack and stiffening pack monitor circuit, that could
roll
back controller current if the NiZN pack is exceeding a safe 'Max Current' mode, or if
the
stiffening pack is running low on capacity.

Simply choosing lower nominal PbA pack voltage would solve this problem,
especially if you have luxury to fine tune it with 2.4V PbA cells.

At least Siemens AC inverters have this feature. Regarding hi amps,
inverters
are limited to 280A battery amps, so PbA don't have to work *that* hard.
May be for 300+ volts low amps systems all this makes little sense.

Ok, so I know that NiZn is much much better than Lead, but what about the
need for individual special chargers instead of one large standard such

that's one of the points of the whole Evercell/NiCad/NiMH scene <snip>
OK, I sharpened my pencil and looked at the numbers again. I was being
smart enough to compare the 64 Ahr Evercels to my nominal 165 Ahr rated
flooded pack, which gets more like 65-70 real life Ahrs (on a good day).
But I was seriously off on the appropriate pack size... 22 Evercels
(MB80s) would give me an 800 pound pack... which turns out to be the
exact same as what Sheer is using. Oops. Obviously if I take the same
pack he uses in a car and put it in my heavy truck, I won't go as far as
he does. To be fair if I fill the same volume as now filled by lead
acid, I would be using 1380 pounds of Evercels at about $9500 (half my
previous bad math) - which matches your estimates of what would get me
the 100+ mile range.
So it is a matter of logistics that I can easily drop 22 MB80s in place
of the golf cart batteries, but I'd really need to design new battery
boxes to work with the Evercel sizes to fit more in. Which makes it a
project for the next truck (or they need to produce some taller
batteries :-)
Consider the cold weather performance of the Evercells (they laugh at
cold weather when lead acid is shaking, quivering, and down to half
> their 'delivered' ahs)
This would of course be a great advantage as I live in the North East.
However, looking at their web page, it states:
"Nickel-zinc batteries can operate from -10°C (14°F) to 50°C (122°F) in
normal load ranges and performance levels. At very high power the
temperature limits are narrower. Charging can be achieved at
temperatures from 0°C (32°F) to 40°C (104°F). Charging outside this
range is possible but shortens the life of the battery."
So if my truck is going to sit in the driveway charging overnight in
January with a low of 4°F and then be driven when all of 20°F outside, I
still need to have some sort of thermal management so as to not shorten
the life of the battery. It is a lot easier to bring the batteries up to
say 40 rather than the 80 that flooded's need, but something is still
needed.
Although if these batteries perform more consistently anywhere within
the specified range, that could help a lot as with the floodeds one
problem is the bigger groups can run 20 degrees or so above the smaller
groupings, which of course leads to balance problems.
> The Evercells on the other hand, are rated at 500-600 cycles at heavy
discharges. If you have a vehicle that has 100+ miles of range per
> cycle, the Evercells then last for 50,000-60,000 miles! When
was the last time you ever saw a pack of flooded batteries do that?
Also from their web site: "Evercel nickel-zinc batteries can provide
10,000 shallow cycles (10% Depth Of Discharge) and up to 500 very deep
cycles (100% DOD) in normal use with approved charging method."
This would indeed be very nice.

In the movie "The Princess Bride", Magic Max the Wizard says the hero is
only "mostly dead". This is in contrast to "all dead", in which case all
you can do is go thru his pockets for loose change, etc.
Well, your batteries are "mostly dead". They aren't going to behave
normally after their near-death experience. For one, they probably did
get sulfated, and now have less capacity, a lower fully-charged voltage,
and higher gassing rates.
What can you do? Simply cycling them and keeping a close watch to avoid
further abuse will help. They will slowly recover, somewhat like an
accident victim gradually getting his health back after serious
injuries.

From the Evercel web site:
"Environmental Status: This battery technology provides the lowest
impact to the environment of any standard rechargeable battery
technology on the market today. Evercel's battery meets the requirements
of the EPA for disposal in landfills with regard to heavy metals. A TCLP
test has been done by an independent laboratory, which confirms that the
Evercel battery does not leach out controllable levels of any heavy
metals. Evercel is working on the EU requirements now. Like all of the
standard rechargeable batteries, this battery system contains an
electrolyte -- an alkaline solution of 20% potassium hydroxide."
So does that mean they are deliberating marketing this as a disposable
battery, destined for landfills? I understand the problem with small
batteries from cell phones, laptops, etc. ending up in the regular
trash, but to set us up to dump large batteries in a landfill is
ridiculous.
What options, if any, are there for recycling NiZn batteries?

The BlueBird QBuses have a nice enough motor, but the controller is not
reliable. These motors should do 200+kW peak. Usually gear reduced to an
output of ~3500 rpm max. So if you have a three ton lead acid pack that
will do 336V and can supply your own 3 phase AC controller (500A RMS
minimum), it's a steal. It even comes with a common driveshaft yoke (for
buses).
I can see a bidding war between Mr Hower and Mr Pullen about to start...

Seeing as I am looking to fiddle with a Sep-Ex motor, I bought a book on
motors in general, and now that I have read most of it I would say I
reccomend it.
Electric Motors & Control Techniques
ISBN 0-07-024012-4
Published by McGraw Hill
$24.95 at Borders books
Covers from the basic to the not so basic, mechanically and
electronically commutated and includes (1994 vintage) controls for
motors. Mentions specifically motors for EV traction.
Book report is over now...

NiZn can be charged in series just like PbA. You need a voltage regulated
charger, and you need to be somewhat careful about finishing voltage - but
this is also true for sealed PbA. Your charger needs to be capable of
starting a timer when a threshhold voltage is reached, just like the PFC-20.

You'd have to check with a current owner to see if the sales contract they signed had
any restrictions, but I seriously doubt that the
state could legally insert a covenant into the contract limiting who the owner could
sell the vehicle to.

Most European countries are less restrictive about importing vehicles than America.

That would be up to the current owner, how they wanted to play that hand.

Disassembling a manufactured vehicle will not legally transform it's status into a kit
car. Chop shops would relish such a concept.
One could ship a vehicle to Europe without "officially" exporting it. Corporate
executives do it all the time. Even simpler, one could just
drive it across the border into Canada and ship it from there. No questions asked.
Then once in Europe, someone could just happen to
have "made me an offer I couldn't refuse".
> What options Euro customer has to get RAV4 EV at all?
Same as the folks in the rest of the 49 U.S. states.
Fudge it.

Lee,
Mostly dead. Ya I like that. After charging and then resting from 11pm to 8am, I'm
usually at 76v or so. I'll keep an eye on the gassing or would that be an ear;)
thanks,
Steve

How about a Miata ?
http://www.austinev.org/evalbum/174.html
They are a lot more "modern" as to the basic mechanicals than a 914, but since they
have been in production since 1990, a base vehicle
shouldn't be too pricey. You could have a shop convert one for you.
If you could happen to find one with a bad motor, the reduced price would offset some
of the cost of conversion.

Musing aloud (?) here on directions to go in my next EV...
I am looking at Kitcars, and the ones I am interested in are all VW
based. I know that there are often motor adaptors available because of
the great number of VW base EVs there are around. These adaptors are
typically for the Advanced DC motors, or the GE, etc.
I am just starting to really think about building an AC powered EV.
I can't say much about AC vs. DC as I drive only series DC EVs. Off
the top the AC system should offer efficient regen. Series DC systems
seldom have regen, and when they do its not usually much or very
efficient. The value of regen will vary depending on driving style,
local roads, and vehicle weight. The low weight will minimize the
value of regen in a VW based kit car.
I can say that VW kit cars make GREAT EVs. The light weight makes
them quick without alot of power. However, now that EV racing is
under NHRA rules I wouldn't count on racing it. Just check out the
special requirements for "VW based kit cars".

There is no tach in the car. The speedometer has shifting marks for 1st
geat at 26 MPH and 2nd gear at 52 MPH. Does anyone have any rough idea how
these points relate to motor RPM and how fast I should drive in 2nd before
shifting to 3rd?
Those numbers should work just fine. Its a little over 5000rpm in
first (standard Rabbit 3.45 first and 3.89 ring&pinion). Its
something about the same in second (there are more gear options
here). Anyway, I highly doubt you could blow a Presto Motor at less
than 7000rpm. I forced my Presto to 7000rpm a number of times - its
still driving my EV buggy. I've hit 8000rpm in another Presto, but I
don't recommend that (though that motor survived just fine). They are
tough, but rated to 6000rpm.

The problem with using a "straw" buyer is the double taxation. The Calif purchaser
would be required to pay the sales tax ( at 8%, about
$3400 ! ), then you would be required to pay the sales tax again in Nevada.
UGH.

Perhaps. From the Rav4EV FAQ:
"Can I install the home recharging unit myself?"
"It is not recommended. Only a licensed expert in vehicle charging units should
install the home charging unit."
So, if you said your brother-in-law was a Master Electrician, and you'd rather avoid
the expense.... maybe.

Hi All;
Yeah, Me, too. Gee, what a nice motorhome conversion they COULD make, be
able to plugitin at Campgrounds for the night. Bettya they need new
batteries, though? What used EV doesn't? They were probably beaten to death,
in service. They must be commercial conversions, like the outfit in TN that
duz buses?
Hope a Lister can find room in his heart and yard for one<g>!Who ELSE
would want one? They should go cheap?
Seeya, on the bus?

Hi All;
I just HAD to dig this little verse out of a Trolley car book ;Season's
greetings!
The Broomstick Train, or the return of the witches
They came, of course, at their master's call,
The witches, the broomsticks, the cats, and all;
He led the hags to a railway train
The horses were trying to drag in vein.
' Now ,then," says he, " you've had your fun,
And here are the cars you've got to run,
The driver may just unhitch his team,
We don't want horses, we don't want steam;
You mayt keep you're old black cats to hug,
But the loaded train you've got to lug".
Sibce then on many a car you'll see
A broomstick plain as plain can be;
On every stick theres a witch astride-
The string you see to her leg is tied.
She will do mischief if she can,
But the string is held by a careful man,
And whenever the evil- minded witch,
Would cut some caper, he gives a twitch.
As for the hag, you can't see her,
But hark! You can hear her black cat's purr.
And now and then, as a car goes by,
You may catch a gleam from her wicked eye.
Often you've looked at on a rushing train,
But just what moved it was not so plain.
It couldn't be those wires above,
For they could neither pull nor shove;
Where was the motor that made it go?
You couldn't guess, BUT NOW YOU KNOW!
Ok a bit dated, but evokes the "Golly Gee! " Stage of electric
transportation, that John Wayland continues today. I can imagine what Oliver
Wendall Holmes would have written up after a ride in Blue Meanie. Below is
his comments on trolley cars in Boston, where they still go today. Btw there
is a Lite rail line across the Hudson in NJ, hoboken, within the shadow of
the Empire State building, or WTC had it lived that long. Trolleys are
coming back, like electric cars.
Look Here! There are crowds of people whirled through our streets on
these new fashoned cars, with their witch broomsticks overhead-if they don't
come from Salem they ought to! and not more than one in a dozen of these
fish eyed bipeds thinks or cares a nickel's worth about the miracle which is
wrought for their convenience. We ought to go down on our knees when one of
these mighty caravans ,car after car, spins by us, under it's mystic impulse
which seems to know not whether it's train is loaded or empty.
I like it, pretty heady stuff. Hope you get a grin from it ,too.
Seeya

Check this out. These guys are really friendly and helpful. You can have a
brand new conversion for 8900, a clutch, a used 914 which can be had for 1
to 3 thousand and 45 hundred for the installation done professionally. This
is well under 20k and it can have a peppier controller put in for some real
tire screeching performance. I have a friend that is loosing his EV1
interested in one. Good luck Lawrence Rhodes....This one uses 20 6v
batteries and has very good range. Lawrence Rhodes....

I made it to Voltageville (Vacaville) this afternoon.
All is well. My EV is lapping up 6kw charging from one
of the many public AVCONs in this city.
I have some interesting charging data when using the
PFC-50 and NG5 in parallel (fast) and using the
PFC-50 by itself off an AVCON (slick).
While I have driven to Sacramento using the public
charging infrastructure before (5 times), it is different
this time. I have a different brand of batteries in my
pack (US145s), different tires, a new charger (PFC-50),
and the charging locations have changed.
I should be at the Sacramento raceway tomorrow,
see you there.
