I already have the car.
I should be able to register it as a kit car, the most important thing is
finding the right battery / motor combination.
I want to right size the car motor.
Car is rolling smart car frame (www.smart.com). I have been looking at 3
wheelers for while, that is why I am trying to figure good motor for slightly
heavier system.
Thanks,
Peter

Subject: New EV - Question
Hello all,
I have been following the group for a few years, and finally got a chassis
to start my EV ...
a smart car ... appx 1000 lbs (without engine/transmission)..
Here are my specs
Desired range 30-40 miles (all basically city driving)
Desired Top speed 60 (or at least 50) or better
Desired Acceleration ... as long as it moves
Original engine was 50 hp (or 60 hp).
If I use the UVE calculator (hempev) starting with CRX at same weight, E-Tek
motor, and the D750, it appears that max continous speed should be ~55-57 (8
hp continuous available), decent range using a tranmission.
If I switch to the A89, hp is more than enough, range becomes marginal (30+
at 40 mph).
Another thought is that the weight loaded (appx 1500-1700) is about the same
as the GEM NEV (loaded). Maybe I could use that transaxle with a bigger
motor/gearing (taller tires than the GEM) to obtain the same performance.
Other recommended motors?
Recommendations, experiences with either approaches, or general comments?
Thanks,
Peter

If they were that price in the U.S., they'd sell a lot better. All

I'd like to do ~60 mph! What fun that would be blitzing through the
neighborhood! Or down the highway! :)
But don't stop at 60 mph! Take those bikes to the limit! 120 mph on
a "bicycle" anyone? But don't stop there..

Now that really burns me up.

The key to electric bike sales in the U.S. is low cost AND high
performance. Slow expensive bikes will never take off from a sales
perspective. There just isn't anything exciting or compelling about
that combination. But if it was fast AND cheap... I'd buy one.

Hey everyone - I'm back! I'm almost finished with college now, and have
started a new project. I plan to use an AC induction motor from the
Ford Ranger EV (Mavin has some) coupled directly into the differential
of a Ford Explorer Sport (they share a very similar differential, same
gear ratio). The only things I haven't considered yet are the AC
controller (Solectria won't work - what're Simovert and Simotion's going
for now or days, Victor?), and the batteries. How are the Thundersky
trials going? Has anyone a recommendation on where to start when it
comes to batteries? I'd prefer it not to be a lead sled. Wish me
luck! Thanks for your responses.
Sincerely,
Sam Harper

I can dream, can't I? Besides, a small enough vehicle, more like a
motorcycle, might be able to find an acceptable wheel motor.
I think that the EVT hubmotor has lots of potential application in something
like this.

The charger has to be compatible for 110v input in order to work.
The Honda EV+ was designed for the consumer market, so they implemented the
ability to recharge on 110v with a special adapter. Unfortunately, the EV
Ranger is designed for a fleet environment, and can only take 220v input. If
you try 110v, it will only get 1/2 of the feed it expects and either fail or
have other problems.

I think the 120 vac avcon plug was included with the Honda EV+ and would only
work with them. I read about someone trying one with their Ranger EV and it
actually discharged it.

How many lbs of ICE is it taking?, I am very curious because I was
thinking along the same lines. What is the weather like in your area?
what color is your truck?
Since the little diet coke plastic bottles(of which I have too many
around) are kinda curvy and would let air circulate around them , I was
thinking of haveing 2 sets of them. 1 set in a freezer in the garage and
one in the car. maybe in a plastic case that drops into cooler.
Re-freeze while I charge and just swap.
If this works well, then I would go to the next stage of building the
freezer into the icechest so it would re-freeze during oppertunity
chargeing as well.

Hi folks...
I had my first experience with direct drive servo system. Planetary
gearing put the servo to tyre with 1:15 ratio. Torque was set to minimum
for these 750 W motors. Ride was quite jerky. When pushing the pedal it
kind of jumped ahead REALLY hard. After it acceleration was smoother.
This was 3-wheeled proto system. Now I feel little more confident to put
4 more powerfull (1-5 kW) servos to one car with same type gearing.
Perhaps only with 1:5 ratio. BUT still lot of unanswered questions...
Has any of you had experiences in using servo motors as driving force in
a vehicle ?
Servos should be quite unbreakable and service free.
One thing I noticed also is that when the vehicle was parked and some
one pushed it from back this proto started jumping back and forth with
about 2 Hz frequency and 20 mm amplitude. I quess servos were trying to
keep their position and while the gearing and tyres gave small slack I
had a inertia problem there. Actually it felt like old idling V8 under
hood waiting to be released wild. (sorry for the V-word....)

Unfortunately the US government put the limits to
E-Bikes. Issues include safety of riders on bicycles.
Now make it into a scooter or motorcycle with all the
lights and federally required safety gear and we'd
have something. FYI e-bikes are neat but in Arizona
they are not permitted on bike paths or sidewalks. Nor
are they allow on any street that is rated over 35
MPH. Limits are placed on bike to not be able to have
motors that develop over 500W or travel over 25 MPH
with Gas, electric or otherwise.

Is it April 1st already? Damn, my calendar must be broken.
I really liked the part about the new hydro drive system that was no loss
of power and is 15% more efficient than traditional chain drives.
I'm guessing whoever created these images wanted folks to know that they
were fakes, otherwise they might have added some kind of steering ability
to five of those bikes.
I think the last one is a real bike though, it looks vaguely familiar.

The problem is that high voltage inverters are hard to find, and because
they're so scarce, they're usually dauntingly expensive.

I knew this would happen, when I threw in this statement. To test you out.
Many people think, even with the ICE they are using the battery power at the
same time they are charging it with any type of charging device. The alternator
is not charging the battery while you are running the starter at the same time.
In a 3 lead alternator, the R-Terminator to the alternator is shut off. In a
2 lead alternator, the regulator is shut down during the low excitation RPM.
Lets look at the science of battery discharging and charging of a lead acid
battery.
When you are charging a battery, the current flow is from the negative plates
which are Pb (lead) and some Sulfate (So4) through the electrolyte which is H2O
+ H2So4 where the Sulfate from the negative combines with H2 of the water
making more acid or (H2So4) and the O goes to the positive plates (PbO2) or
lead oxide.
This direction of flow is the charging cycle.
The other direction from the positive to the negative (inside the battery is
the discharging cycle or taking energy from the batteries)
You cannot make this flow of energy inside the battery go into two directions
at the same exact time. You are either charging it or discharging it.
You can draw energy from a battery if the charging system voltage goes below
the battery voltage, this is where the charging system is no longer charging
the battery.
If the demand of other loads that is connected to the battery and charger is so
great that the charger is providing all the energy to other loads and is not
charging the battery, the battery is being used at that time.
Also if you pulse the charging ON and OFF, the battery CAN BE USED during the
OFF cycle, but not on during the ON cycle of the charging system.
This pulsing cycle is so fast at times, but the battery current is going one
way during the charged cycle, where the battery is not providing any energy to
a outside load. Only when the battery is flowing from Pos to Neg (inside the
battery) its providing power to a outside load.
Don't confuse Pos to Neg flow (inside the battery) with the Neg to Pos flow
(outside the battery) which is the samething that provides the circuit ( a
circle) direction.
When I taught Basic Electricity, many students of which some of them are
electronic technicians and electrical workers. The electronic tech. would say
the electricity flows from Neg to Pos and the electricians said NO, its flows
from Pos to Neg. They both corrected in one was thinking inside a battery or
generation system and the other was thinking outside the battery or generation
system.

I've always done that. Am I breaking the law or something? Are only ICEs
allowed to use their 12v batteries while charging them?

Sweeeeeet, Nick! Yep, brings back exact same memories of me at my local Honda
dealer about 6 mos. ago. Thanks for sharing it. (;-p
Nick Viera <[EMAIL PROTECTED]> wrote:Hi everyone,
The other day I went to the parts department at my nearest Jeep
dealership to get a part for my (ICE-ed) Jeep Wrangler. I'm paying for
it, and the head parts guy asks me "Hey, so what ever happened to that
old Cherokee of yours?". I was surprised he remembered me as it had been
well over a year since the last time I was there. He continued with "You
didn't get rid of it, did you?"
The stage was set... so as usual I nonchalantly delivered my
to-the-point message that "No, even better. I converted it to an
Electric Vehicle. No gas, no emissions, and I love it!"
I've found that around here people react in one of two ways to such an
announcement; they either ignore it completely or they begin repeating
what they just heard loudly to get the attention of others in the
general vicinity, so everyone will hear the 'crazy thing' they just
heard. This parts guy did the latter, and quite effectively got the
attention of the other five guys working at the parts desk. To my
surprise they all seemed very interested to hear about an Electric Jeep.
They wanted to see it and encouraged me to bring it by (I was driving my
Mazda that day). I told them I'd stop by tomorrow and left. I was
figuring that I'd stop by and show the Jeep to these guys for a few
minutes, maybe give a test ride, and be on my way...
I got to the Jeep dealership yesterday around 4:30pm and parked in the
lot outside of their garage (the parts department is located in a
"building" inside the far end of the service garage). I announced my
presence to the parts dept. and was told to just drive it right up close
to the parts desk. There weren't many cars being worked on at the time,
so the big garage was surprisingly quiet yet full of service technicians
just hanging around. Well, needless to say I got a _lot_ of stares as I
came driving in... my shiny Cherokee just gliding right through the
garage making no noise.
I pull up by the parts dept. "building", park, open the hood, open the
tailgate, and begin the process of showing my EV to some of the parts
dept. guys. I kid you not, within 10 seconds my Jeep and I were
completely surrounded by a sea of navy blue uniforms as (apparently)
everyone in the parts and service depts. came over to check out the
mysterious vehicle that had just parked at the end of their garage.
There were all the usual EV questions being thrown out, (not
surprisingly) many of them were more technical questions than I'm
usually asked. I did my best to answer each question before the next
one, and was just relieved that for once I didn't get any of those "wind
turbines/ generators on the wheels" type questions. After a solid 35
minutes of answering questions, the crowd began to disperse as these
people returned to work. A few of the parts dept. guys who were really
interested hung around. I offered to give some "test rides" and did.
First it was just me and the head parts dept. guy. As soon as we got in
the Jeep a crowd had once again formed around my Jeep as these people
scrambled over to see and hear my Cherokee depart. I turned my Jeep on,
hearing the slight whir of the vacuum pump and Zilla cooling fan then
the loud "clack" of the main contactor engaging and announced to the
crowd that I was going to move now (apparently these people didn't
believe me when I told them the Jeep was ready to move as some of them
were *still* standing in front of it!) The garage has a relatively long
drive out the back, so I took advantage of that and commanded the Zilla
to make me *move* off the line. Judging by the audible reactions, they
were really surprised/impressed.
I wasn't to familiar with all the streets around this dealership but
tried picking about a 1.5 mile route for the test ride. So I'm going
down the first street that I pick and all the sudden here's this really
*steep* hill out of nowhere. Probably the only significant hill in this
area and I just happen to pick the street that goes up it. To make
matters worse I had to almost come to a stop at the bottom of the hill
to let a car get through (cars parked on both sides of the road). I
floor the accelerator to start up this hill in 1st gear with no problem,
but notice the ammeters reading a solid 850 motor amps/400 battery amps.
I'm thinking to my self "$#@& this is _really_ going to heat up my
motor!!!" while simultaneously commenting to my test-rider "See,
Electric Vehicles do climb hills just fine" :-)
Well, we got back, my rider jumped out and began telling everyone how
cool and unbelievably quiet the vehicle was. I loaded up two more parts
dept. guys and headed off for test ride #2. Did mostly the same route,
but without the hill from hell, and returned. Now there were three
people railing about how neat riding in the EV was. Well, there were
more people who wanted test rides, but couldn't because they had to get
back to work. Though, I ended up hanging around and answering more
questions and talking about EVs with these guys for another 30 minutes
or so. Eventually I had to get going, realizing that it was 6:00 and I'd
just spent an hour and a half at the Jeep dealership... so I got going
(again, to a small crowd of people watching as I silently drove off in
my EV.)
I guess what makes this impromptu EVent stand out in my mind was that
here was a shop full of people working for a dealership for a major auto
manufacturer yet who were surprisingly open minded to and interested in
the idea of Electric Vehicles. Even more interesting, I thought, was
that a good number of them knew about the EV1, TEVan, and other
auto-industry built EVs, and on their own started wondering why the auto
makers are refusing to build EVs. Good food for thought... and I didn't
even have to prompt them!
So that's my latest EV awareness/publicity story. The lesson for me was
that sometimes the group that you think will be the least interested in
an EV will actually turn out to be the most interested in an EV. :-)

For this vehicle, just add water
By Bob Downing
Beacon Journal staff writer
Starting Monday, a special car will be in the
spotlight in Akron.
It's a Toyota Prius prototype that runs on hydrogen
instead of gasoline.
It doesn't pollute -- it gets its hydrogen from water.
And it's not a vehicle of the future -- it's on the
road today.
The vehicle was developed by Michigan's Energy
Conversion Devices Inc. (ECD), its subsidiaries and
the company's Akron-born inventor-president, Stanford
Ovshinsky.
Ovshinsky is bringing the car to Akron along with a
model of a service station where the vehicle could be
refueled. His goal is to demonstrate how equipment
that separates water into oxygen and hydrogen could be
installed at service stations.
There will be a news conference at 9 a.m. Monday at
the University of Akron, and the car will be on public
display from 11:30 a.m. to 1 p.m. at Lock 3 Park.
Tuesday, the vehicle will be taken to Portage Country
Club for a private luncheon with Akron's congressional
delegation and auto industry representatives. At other
times Monday, Tuesday and early Wednesday, the car
will be taken on test drives.
Ovshinsky also is bringing to Akron a hydrogen-powered
lawn mower, scooter and a three-wheeled taxi cab like
those common in Asia.
Akron's deputy planner, Jeff Wilhite, said the event
is designed to give the public an up-close look at
Ovshinsky's work.
Ovshinsky and his wife and collaborator, Iris, of
Rochester Hills, Mich., are planning to open an Akron
laboratory late this year or early next year to test
hydrogen fuel storage tanks. The laboratory is
expected to produce 25 jobs in its first three years
and 125 jobs by the end of the fifth year.
Wilhite said Akron has a bigger opportunity to tap
into what Ovshinsky's company is doing.
But the window to make that connection is small,
probably less than one year, Wilhite said, and Akron
investors would probably have to provide $40 million
to $60 million to start producing the storage vessels
and other items needed by Ovshinsky's company.
Companies would have to work out licensing agreements
with ECD and get the tanks and related equipment
certified by three federal agencies before large-scale
production could begin, Wilhite said.
The hydrogen for the Toyota Prius prototype is
generated from water via electricity from ECD-produced
solar panels. Hydrogen is pumped into the car as a gas
and stored in tanks as a solid by bonding its atoms to
a metal powder.
The hydrogen, when heated from the engine's cooling
system, becomes a gas again before it is burned in the
car's engine.
Wilhite said city officials have suggested that
Ovshinsky's company might be able to tap into Akron's
drinking-water supply as a source for its hydrogen.
The water system was set up decades ago to provide
drinking and production water for Akron's
once-thriving rubber companies. But the water once
used by the rubber companies today is surplus that
might be usable as a hydrogen source, Wilhite said.
Ovshinsky was born in Akron in 1922 and opened a
machine shop in the city after graduating from Buchtel
and Hower Vocational high schools.
He later founded a field of physics called ovonics,
based on the semiconductivity of certain alloys. He
holds about 300 patents, including the nickel metal
hybrid battery that today powers all hybrid vehicles.
Ovshinsky founded his company in 1960 with his wife.
The company has widespread manufacturing facilities
and numerous joint ventures with other companies.

The charger has to be compatible for 110v input in order to work.
The Honda EV+ was designed for the consumer market, so they implemented the
ability to recharge on 110v with a special adapter. Unfortunately, the EV Ranger
is designed for a fleet environment, and can only take 220v input. If you try
110v, it will only get 1/2 of the feed it expects and either fail or have other
problems.

I planned on wiring a universal input charger with the Avcon setup, so it
wouldn't be a problem using the 110v line in that application.

Mine is more like a couple of feet with a Curtis 1231C. Enough to run

I can look it up on Monday to see what size and such if you want me too.
Sounds like the fan is a little cocked, easy fix. Amps sound good, but it's
probably a smaller 6 inch I'd bet. Let me know if anyone wants me to look into
motor size on monday.

An interesting question!
A human/electric hybrid seems like a naturally good idea. A very small
light vehicle can easily be powered by the rider on flat ground at low
speeds in good weather. But there are hills, hot weather, bad knees, and
circumstances that require a bit more speed. An electric boost makes the
vehicle a lot more useful in a much wider range of circumstances.
I'm thinking that something like a recumbent 2- or 3-wheeler could carry
the extra weight of motors and batteries, be more stable, and more
comfortable to ride for older people and for the longer distances that
such a hybrid would encourage.
If a 3-wheeler, it could have a solar panel "roof" to keep the sun off
and recharge itself. It could also be stable enough to have a small
cargo capacity for groceries and the like.

Hello to All,
OK, it's Saturday morning, the day after.....Last night the deadly trio
of Tim, Jeffrey, and Plasma Boy returned to PIR with the Silver Bullet
to see what we could squeeze out of it in the 1/4 mile as a follow up to
last Wednesday night's 1/8 mile runs. We're having a lot of fun racing
this whistling beast, but we're also a bit disappointed in the ETs we're
ending up with :-(
I posted that the best ET from Wed. was a 9.8, and Ken Trough had asked:
Doesn't that mean that the Silver Bullet broke through the 100mph
barrier for street legal cars?? I realize that this was not a
sanctioned NEDRA event and that the times are probably not official,
but how about some timeslip details?? Drool.
Others have already addressed this, but I'll also reply. Ken, Wed.
nights at PIR are strictly 1/8 mile only, so the 9.8 was in the 1/8
mile, not the 1/4 mile. In that post, I had written:
Last night Jeffrey Bywater, im Brehm, and yours truly took the Silver
Bullet for shake down 1/8 mile runs to PIR...so his 1/8 mile times
were around the 10.0 - 10.2 second region, but once he figured out the
linkage thing and started to nail his shifts, things got better. The
Silver Bullet's best time was a 9.8 second run.
OK, back to last night's '1/4 mile' runs....As stated, the car runs a
lot slower than we had hoped for, with ETs never getting close to the 14
second range and in the high 15's with a 16.2 thrown in to make it sting
a little more for the 5 runs it made. The best ET was the last one of
the night at 15.695 @ 82.15 mph. Still, it generates tons of excitement
at the track. Jeffrey has turned into a good drag race driver and nearly
nailed the $50 award for a perfect reaction time with his .001! In fact,
all of his reaction times were super, at .001, .053, .027, .028, and
.021, pretty darn good for a newbie drag racer!
Even with tepid ETs, the race fans and fellow drivers all love this car.
Many have seen another little EV run low 13s and so know that electric
cars 'can' get the job done. One of the most fun races of the night, was
when another silver Datsun 280ZX pulled into the pit area right near our
camp. The guys had this Z Car, plus a pretty hot green Rabbit that was
running mid 13s. They immediately came over to see what our Z had under
the hood, and just about fell over when they saw those three electric
motors under there! We all became friends on the spot....very fun
evening with them.
I arranged with 'Big Jim' in the staging lanes to have the twin silver
Zs run against each other, and the crowd loved the grudge match. Out of
the hole, Jeffrey stuck it to 'em with the Silver Bullet lunging off the
line, tires squealing loudly, nose up high, and easily dusting the
gassser Z badly at first. Jeffrey banged 2nd and lit up the tires again,
then grabbed 3rd and was still pulling the straight six Z next to him.
It wasn't until the final leg of the race that the gasser Z was on cam
and humping hard as it finally blew past the Silver Bullet and on to a
14.7 second run, with the Silver Bullet only managing a 15.7...oh well.
It was great listening to the crowd's reaction to the way the electric Z
had initially accelerated out of the hole. The best part though, was
when the other Z driver came back to the pit area, his mouth going a
million miles per hour about the way our Z had embarrassed his off the
line, "Geezzz, that thing's got TORQUE! Geezzzz, it freaked me out. I
mean, mannnnnn, it's unreal!" He went on and on about the way it blew
his car into the bushes for a while, and he commented on how he didn't
think his car could catch ours as he saw the Silver Bullet's taillights
most of the way down the track. He and his crew spent a lot of time
admiring the electric Z, and they all seemed ready to make an electric
drag racer of their own....better watch out for these guys. It's really
too bad we didn't have someone there with a video camera to catch this
classic Z battle.
We struggled to get the car fast through the 1/4 mile, and even tried
disconnecting one of its three motors to run on two motors...the ET went
down from a 15.9 to a better 15.7, but we all thought the difference was
most likely due to the batteries warming up with each run. We confirmed
this when we reconnected the third motor and ran a similar time the next
run. Before the last run, I checked the calibration of the master
Raptor's throttle solenoid and found it way off. Adjusted for best WOT
(wide open throttle), Jeffrey reported he finally saw the yellow current
limit LED lighting and the Z dropped 2 tenths off the ET to its best
15.695 @ 82.15 mph.
OK, what's wrong? We don't know for sure, but we do have our ideas on
the subject:
(1) When we got the car a few weeks ago, it had been left out in the
weather, was banged up a bit, and had cracked and in our opinion
dangerous rear tires that had sat deflated with all the car's weight
crinkling the sidewalls. Rudman stepped up and supplied us with his
sticky BR Goodrich TA drag radials, the same models I use on White
Zombie, for us to try on the Z. They are a far lower profile tire than
the ones we pulled from the car, but better in all other ways. Rudman
had predicted that their smaller diameter would limit the car's top end,
and we think he was right...damn, I owe him a dinner on the lost bet
over this! With the same high quality drag radials but in a different
diameter, we're thinking that much taller versions will really improve
the top end to bring the car closer to the 14's and bring the 82 mph
trap speed closer to 86 - 89 mph.
(2) The motors seem to be timed at neutral and just don't pull like
they should. On this, Rudman and I agree. Taking the triple motor
configuration apart, twisting the end bells, redrilling the bolt holes
and reassembling the affair would be time well spent. This change is
probably the most needed, and I feel it could push the car deep into the
14s, maybe even into the high 13's.
(3) The suspension is really in need of attention. The car nearly
scrapes its rear bumper on launches and the nose takes on a 757 take-off
effect. Reworking spring rates and shock control would more than likely
trim off a few more tenths.
(4) Perhaps as much as 200 lbs. of weight can and should be removed from
the car.
All the above considered, it amazes me that this car ever managed its
world record best at 156V with its 14.77 ET....how did Father Time pull
that one off?
Everyone is attracted to this machine and we know it can get much faster
and quicker. I've got a great group of younger guys filled with EV
enthusiasm that I work with and have drug into this whole electric drag
racing scene, so with Tom True's permission and Father Time's
involvement, they can really help to get this thing into the fast lane
again.
For now, it's back to White Zombie this Saturday. Tim and I have been
getting frustrated with time delays on everything, but we're working on
this. The delays did make it possible to play with the Silver Bullet for
the last two weeks :-) Marko will be getting the final metalwork done
that's needed for the major under-hood redesign I've got going on. The
aluminum driveline should be done in a week or so. Today, the two
modules that make up the 348V battery pack are being assembled and the
29 batteries will all be bolted in securely, when we receive the
hold-down brackets.
OK, off the computer and out the EV shop I go!
See Ya........John 'Plasma Boy' Wayland

Connecting the Heinemann(Heinemann 160 VDC, 250 amp continuous, 1000 amp
peak) seems like an exercise in insulation. It just has two bolts pointing
down. The instructions say keep the switch horizontal. I want to install
it in the floor next to the stick shift. I see that I can extend the bolts
a bit but can they take the torque needed to secure the switch. I don't see
how else it could be done except by drilling two holes across the switch and
over the bolts and securing it to the center hump in which case it will
follow the angle of the center hump. A little rubber or plastic top hat
without the top would be all that's needed if the bolts can take mounting
torque. Thanks for any info on installation. Of course if this switch goes
through the floor it must be insulated very well.

I agree with Lee. These bikes are situp bikes. The best bike to convert to
EV status is a recumbent(because of wind resistance) Mikes Better bikes in
Palo Alto has done a few that can be ridden/peddled as far as 200 miles per
day. He'll sell you everything up to and including a fully converted
bicycle. The fairing is the most important part.
