<<<Well the money is there and think it would be lots of fun to do but only if
its a significant cost savings over gasoline power.
Randy>>>
There's little chance you'll spend less overall on an EV than your out-of-pocket
expenses runnning the original ICE - saving money is not why most people do a
conversion. The price of electricity is the least of your worries - add in
amortorizing the battery cost (and then the conversion cost itself) and you'll
see why folks do it for the challenge, to cut pollution, or for the fun of a
near-silent high-torque takeoff, but *not* just to save their dough!

dose anybody know what the max continues draw could be on these could be .
I'm thinking about them for my lawn mower project and might need 100 amp for
15 min. also would like to fast charge them back, like maybe at 50 amps .
steve clunn
certainly get you dimensions. With the BB600 the only dimension you
really
need to worry about is the height which is approx. 9 1/4 inches, but they
do
require occasional watering so you will need easy access to the tops of
them. Also they are flooded so they need to be used in a vertical
position.
These people used to sell them, but it's been well over a year since I
last
checked with them. Still you can see a photo and the dimensions.

Hi Randy,
It can be done. The biggest issue with using vans as highway EVs is
drag.
While most vans have about the same drag coefficient, you can increase
efficiency by reducing frontal area. Are you considering an E150
because
you have one? If not, you might want to consider an Astro, or an older
smaller Econoline from the 60's or 70's.

Agreed.
>From time to time we get posts from folks who say something like, "My
beloved old [Chevy/Ford/Whatever] has a dead engine, maybe I should convert
it to electric." They're thinking it will be cheaper. There are ways of
doing a conversion on the cheap, but in most cases, it can't beat the cost
of mass-produced aftermarket ICE repair parts. More to the point, it's not
just pull the engine and bolt in a motor - there's much more to a conversion
than that!
Not saying this is the original poster's intent, but for those who are
looking for a way to keep an old friend on the road - if what you want is
the cheapest possible transportation, get a boneyard engine and drop it in.
You'll be good for another 50,000 miles or so of polluting the air and
burning up imported petroleum (a deliberately provocative statement; ah,
forgive me; so hard to resist! ;-).
But if you want a challenge; you want the smoothest, quietest ride you've
ever had; you want to be able to say you're using no foreign oil (eh,
probably depends on where your power comes from ;-); you want a zero
emissions, highly efficient vehicle - then convert!

I think the main problem of a conversion van is that most of its weight
hauling capacity would be taken up by batteries and there would be
little or no capacity left for hauling people and cargo. What's the point
of having a big van body with little or no hauling capacity?

Randy,
I have an electric 1961 Corvair Rampside pickup
that I think is pretty closely related to your van. It
was converted by a high school in AZ in 1997. The
competition they built it for had a limit of 96V. This
wasn't really enough to run the ADC 9" motor
efficiently, but it did run. I bought it last year
with it's abused pack of generic batteries. It was
good for about 25 miles per charge. It could get up to
75mph on a flat stretch of highway (a tail wind
helps).
I'm currently installing a Zilla controller and
144V US battery pack. I'm hoping for a 100 mile range,
but will be happy with 75, it's not very aerodynamic.
I'm hoping to have it back on the road by next week. I
can't afford to keep gassing my ICE truck.

what's a Dustbuster??
I too am interested in making an RV that gets good
mileage as that will be the thing of the future. When
I realized it would cost $1000. just for fuel to cross
the US I gave away my motorhome.
Since I am retiring this year and will therefore have
the time this fall I have decided to drive my Insight,
towing a small teardrop camp trailer, to Florida in
the fall to help build my Freedom EV Glider. I will
sell or abandon the teadrop in FL and tow the freedom
back.
As time gets neared I would like to plan a route that
goes by as many EV groups or interested individuals as
possible. If you have an interest and live along the
southern route across the US contact me off list

I'm concerned about leaving the Iota DC/DC on during
charging due to the finish voltage of a 144V pack
being pretty close to the upper limit on the input
side of the DC/DC. I went with the Iota DLS-55 55amp
converter. It's going in my '61 corvair that doesn't
have much of a 12V load in it. The headlights and the
wipers is about it. I'm planning on a radio someday,
and an interior light would be nice. I think the
original generator that they came with was 30 amps or
so. I think I'll be OK running the Iota at 14.2V while
I'm running the truck. I guess I'll keep an eye on the
12V house battery to see if it's working out OK. It
has to be better than the 12V loss system the truck
came with.

A Dustbuster is a small hand-held rechargeable vacuum cleaner.
GM built minivans that looked like Dustbusters from about 1990
through 1996. They included the Chevrolet Lumina and the
Oldsmobile Silhouette and a Pontiac that I can't recall the name of.

I tested mine before I put them on my motorcycle. I only tested them at a
60 amp draw, but they all lasted for at least 40 minutes giving me 40ahr.
They will do your 100 amps for 15 minutes easily. You also won't have any
problem fast charging them. I was at Waylands house one day and we were
pumping in well over 30 amps.

Hello Lee,
thank you for interesting information. I think someone in this thread mentioned

Thanks Damon , one more thing , any idea how they would handle the bumping
around which a lawn mower sees .
I picked up another mower like the one I use , with a bad engine , its even
a newer model , and I have a 8" motor and 72v altrax controller , Here is a
picture of the mower 10 years ago with my first ev .
http://www.austinev.org/evalbum/247b.jpg I am going through allot of the
same thinking presses I did when I did my first EV
1 got a donor that was cheep , now if it works I'll have lots of odds and
ends to fix that I wouldn't if I spent 10 times the money and gotten
something in better shape.
2 I depend on it for my job , can't be working with a "science project" .
3 What batteries will be right for the job.
same kind of stuff people do with there first car conversion.
1 some of the things I have going for me are that both the blades and the
hydro's ( which drive and steer the mower) are driven form pulleys on the
motor . I can change the size if I need to run the motor at different rpms.
2 I can justify spending the money as a business expense.
3 I don't think that most of the time the gas engine is having its 20 horses
worked so it may not use as much power as I;m thinking . .

I remember trying to find that figure on google and came to

the Cd of the Lumina van to the Corvette of the time.
There is a lot of room for improvement. I don't think it's
at all out of the realm of possibility to get that figure
down to the .25 level.

Both these are changing the face of aviation and I

I have a Iota 30 on my 150v work truck and leave it on when the charger is
on , I did have a problem one time when an extension cord melted and blow
out so I really need to do something also. . You could set it up with a 160
v zenor ( put a munch together in series ) and an N. C . relay ( when
voltage gets high form charging and zenors start passing current to relay ,
relay closes which shuts off power to dc/dc ) that would disconnect it when
the voltage gets over 160 ( or where ever you set it for.) then when charger
shuts of and voltage drops , your dc /dc would come back on . there would be
lots of ways to set up the relay,

Hi folks,
I believe these are Texico Ovonics they were used in the NiMh version
of the EV1 and the GM S10, offered as an expensive option. They almost
gave NiMh a bad name due to thermal issues, as the formula was a little
different than the successful Panasonic 95 ah used in the Rav 4. Keep
them cool and good luck.

Steve,
This is an apple to oranges comparison, however it
might give another perspective into EV mower power
usage. Check this out;
http://www.jacobsengolf.com/products/riding_greens_mowers/e-plex_ii/
I tested one of these on a Lincoln, NE golfcoarse on a
cold spring day with 40 MPH wind gusts. I'm guessing
the batteries were at 15 degrees C sitting in the
garage.
It used 6, 8 volt Trojan deep cycle golf cart
batteries, a GE sepex motor and 300Amp control, and 3
BLDC motors/controls for the reel mowers.
All 18 greens on rolling hills were mowed and we had
plenty of juice when finished. Sorry, I don't know
the state of charge when finished.
Good luck with the conversion!

Trojan literature mentions the J150 as a simular footprint and more powerful
replacement for the 5SHP. They are mentioned along with the T105 as a Floor
Machine battery. How do these 12v units hold up? I've heard not as good as
a T-105. Lawrence Rhodes.....

5Shp Three more amp hour. Not as tall and one pound less weight. How do
these batteries hold up in EV use? LR.....
I'm working on a converted Mayflower(small British car that looks like a
Bently) It weighs around 2000 pounds unconverted. The Interstate
batteries didn't work out that well. They are being taken out now. I do
suspect undercharging. The rear batteries were bulging from sulfation.
What would be a good Trojan replacement or are the Interstate good
batteries. I haven't heard they were. However at 1000 pounds in weight
they are a good size to get 120v in a small car with a savings of 400
pounds. I need a Trojan with the same footprint and amphour and haven't
found it yet.

I have 40 of them in my Sears Craftsman Garden tractor
with a hydrostatic transmission. Yes I have only done
two mowing with it but they seem to work great with
the ETEK that is running them. I only briefly see 100
amps most of the mowing is at 65 amps. The 100 amps
was 10 inch high thick grass and I was going slowly
through it to mulch it up good going any faster was
about 90 amps but left clumps.
It may just be the EVness that is getting to me but I
have to say it is a whole lot better mower then it was
before mulching much cleaner and going up hills
faster. I'm going to try dropping to 36, 42 or even
43.2 (4 9 cell packs) volts for the next mow because
48 volts actually seems like too much.
Since the motor always goes one speed it still seems a
waste of money to do a controller since I am using a
PM motor.

EV-145 is also a candidate. So far Interstate U-1450, Trojan 5HSP, US
EV-145 or Trojan J150 I think.

Its obvious.... the hauling/space/cargo capacity is used. It is being filled
with batteries so the function of the vehicle is being performed. It's just not
being used in the 'traditional' way, which requires a sort of paradigm shift of
thinking....
I think there is a figure that someone has published based on studies done that
show that 90% of the cars/vans/trucks driven have one occupant, the driver, and
are not loaded in any way.
I'm lucky enough (or unlucky enough when I go to the pump and fill up my 80 gal
tanks) to have a F-250 diesel so if I need a vehicle to haul/load I can. But my
main vehicle will be my S-10 with 30 T-125's that will get me a round trip to
Tucson (70 miles). I've also decided that I will sacrifice the bed of the S-10
and put the batteries directly on the frame back there with a much smaller
custom made cargo area. The Bed weights about 250 lbs and the 'new' bed will
weight much less. I can also cut off a foot of the length by removing the last
foot of the body frame that will not be used since the original bed will be
removed.
Since all the batteries will be mid frame that leaves the engine compartment
available for electronics only.

Hi Tim
Changing the thread from 'conversion van'...
I'm converting a S-10 and will be using 30 Trojan T-125's in the rear. I'm
removing the bed and will make a custom bed/battery holder. I'll be using a
Zilla with a 9" ADC motor. I figure that I'll get about 85 miles if I use 300
with per mile. I'm also thinking of getting a battery watering system if I can
get one for a good price. Watering 30 bats seems like it would be a drag
I did some spreadsheets on the 105's, 125's and 145's and the 125 comes out as
the most efficient for wts per lb. I've also been able to get a real good
price, $58 with core, for the 125.
Where are you located? A friend and I want to start an EV group here in Tucson
for trouble shooting, meeting for 'workshops' etc.

Hello,
What contactors should I use for a 180 V system? Where can I get them? I want
2, one for the key switch and another for my Zilla. One will be on the neg path
(key) and the other on the pos path (Zilla?) of the bat pack. Amp wise I am not
sure what it should be.
Will a Kilovac Cozonka lll, EV-200 work for me? It has 250 amps continuous. My
battery pack will be 30 Trojan T-125's.
Thanks for the help.

Lead has been around and used for a long time. NiCad has always been
lurking in the background, but never dominate. Is Lithium always
going to be this way too?

While you will have to be thoughtful about it, it
can be done even at today's gas prices.
But first you need to select a better
body/chassis than a large Ford Van.
One of the Dustbuster ones mentioned already or
other of the Mini vans would be much better.
There are already some made, the Chrslyer T Van
EV built on a Caravan body can be found for sale
regularly on the internet may be good for you.

Only floodeds will give you the costs you seek. AGM

Depends on the vehicle but generally on a good EV,
about 50% of the vehicles weight in lead batts of the
flooded type.

Costly and unnessasary. Stick with 120-144vdc.

That probably won't do his range requirements.
24 T125's $1440

Several others around $1k

Several at under $1k

About $6k depending on how you want to go.
At 10k mile/yr, it will take you about 2.5 yrs
to recoupe your cost by gas savings that doesn't
include maintaince savings you get with EV's vs CE's
and the price of gas is sure to go above $2.50/gal.
You also get a 10% fed tax credit and your state
may have other credits.
You also save a lot in no car payments over
about 10 yrs with just small maintaince and batt
replacement every 20k miles or so.
If I was going to do it, I'd go for a Dustbuster
van
22 t125's $1220
Contactor Controller 300
Forklift, surplus Motor 300
own built chargers 100
Misc 1000
$2920
This could be paid back in 18months or less in
gas costs.
Though depending on the actual use it will do,
I'd go for an EV based on a small pickup frame, cab.
So as you can see, there are different ways to
do this.

Lead-acid is still the most widely used rechargeable battery because it is
cheap, easily recycled, and "good enough" for most applications. It is likely
to maintain this position for a long time to come. The only thing I see
interfering would be an irrational political reaction to ban lead, like we have
done for asbestos, mercury, DDT, PCBs, and other chemicals.
Nicads have been around a long time, too. But they are fundamentally more
expensive, and so have only dominated in small sizes where cost is less of an
issue than convenience and their greater energy density. Sealed nicads are the
easiest-to-use rechargeables we have, though flooded nicads need even more
maintenance than flooded lead-acids. The big problem with nicads is that we
have ignored recycling, and allowed them to be treated as throw-aways. Cadmium
is very toxic, so the only way nicads have a future is if we insist on strict
recycling (as we do for lead-acid).
Lithium based batteries are very interesting, but still undergoing rapid
development. They are expensive, and have lots of unanswered life, safety, and
recycling questions. The devil is in the details.

John, I think that they could lower their CD
nicely from their stock .30CD
They weigh about 3400 and stripped of their ICE
and other unneassary stuff, down to about 2600lbs. Not
a bad weight fr it's size and with it's good aero
could make them good EV's.

It's both bad aero and too much weight that
hampers RV's but both are easy to fix if starting from
scratch.
And the Dymaxion is a great starting point for
it!! And in Fla it's still considered a MC!!!

As the Freedom EV glider will only weigh 500lbs or
less, you could just build a quick and dirty plywood
trailer camper.
Then put the Freedom Ev on the trailer or make it
so the camper fits over it. Though the Freedom being
very aero, would be good by itself and save the weight
driving back.
And you can set up the Freedom to sleep in it!!
