This really depends on the spectrum of the "noise maker" Fast switching
can have harmonics into tens MHz. Powerful but soft-switching
controllers/inverters are better in that respect.
In addition, aircraft comm. and navigation gadgets perhaps have better
filtering than car radio.
I'm in agreement with you, my point was going to FM is far more
effective in suppressing (rather "ignoring) AM noise than just
increasing AM carrier frequency.

At 100 MHz but AM, mod the noise from the radio would be almost
as horrible as at 1600 kHz.
Actually, no. AM is used on VHF radio for some services (notably
television and aircraft radio); it has a little more noise than FM, but
not much.
Broadcast FM radio owes most of its noise immunity to being higher
frequency (so impulse noise is greatly weaker), and to being wideband
(many times wider per channel than broadcast AM).

ACRX is essentially "clutchless". I have clutch, but it's so stiff
(otherwise slips) that linkage cable jacket shrinks enough to
prevent full dis-engagement (sp?) so I ended up not using clutch
at all, and didn't miss it. It is on the second gear at all times.

The radio in my '87 Cabriolet works fine with CD, Ipod, and FM. AM is only
useable when my foot is not on the go pedal :)
I managed to twist the long 2/0 cable that runs from the back to the front
of the car. I also twisted the wires to the traction motor. I tried to
keep 12V wiring away from the high voltage stuff, but it's nearly
impossible... I have 4 high voltage wires running across the engine
compartment (contactor to hairball, battery pack to DC/DC), and several
12V wires that run directly under batteries, near the Zilla, next to the
motor, etc...
I could probably get AM with some shielding - grounding the case of the
Zilla would be a good start.
Radio is an Alpine CD9847 with hideous amounts of 12V wiring behind it.
Speaker wires are unshielded and run all the way to the rear deck. The
Ipod is connected with an RCA input adapter.
I'd be surprised if you didn't get decent FM reception, even with
non-ideal wiring.

I had 2 clutchless EV's. Both ran on DC. My experience was not as good, and I
don't recommend it.
Safety issues - no mechanical disconnect
Performance - it does take longer and is more difficult to shift

Babel fish translation.Eicma 2006: An electric MP3 at Vectrix! The American
firm Vectrix presented at the Living room of Milan, a version 3 wheels of
its electric scooter already marketed in Italy and on some points in France.
Vectrix is 100% electric and is placed on the level of performances a 250cm3
in acceleration with 0-80 km/h into 6,8 dryness and a maximum speed of 100
km/h. Autonomy is given for 110 km with 40 km/h or 5 hours in the urban
traffic. The scooter is designed like a large machine with two places with a
trunk for a helmet. The batteries are in central position and the refill
with 80% is carried out in 2 hours. This scooter integrates a system of
refill in deceleration which also provides an electric function of braking
without having to touch with the brake and a reverse gear. The batteries are
in Nickel/Metal Hydrat without maintenance. Are the models for Europe
produced in Poland and the current price of the scooter is 6299? cash and a
4 years leasing to 150? per month including/understanding the insurance,
maintenance and the assistance with the guarantee 4 years. The 3 wheels is
for the moment a proto which will be produced for a 2008 just like hybrid
version with fuel cell in order to carry the autonomy of this scooter to
more than 250 km.

http://www.austinev.org/evalbum/727 Mine is now clutchless and a great
improvement. Shifts faster than with a clutch, more power off the line.
Unless you are building a race car, not sure why a clutch is even
considered. The synchronizers do the work fine, you save all the angular
momentum of spinning up that clutch and flywheel. Slows down faster at
traffic lights, saves braking.

H i Steve and all
for those trying to deside , a little more info would be good , like the size
of your motor , voltage , and size of controller ,,,, My guess is you have a
under 144 v pack , somewhat heavy car , small motor . So you do a lot of
shifting. By a lot I mean from every stop .

don't think the type of car makes as much of a difference as what parts are

Hi EVerybody, and the Nicad Folks;
Watching the Charging Follies here, hoping to do it close to correctly
when the time comes? A few observations, as covered in the
chronicles(comicals) from before, I blew up a pack of 5 Nicads with the time
honored spark- around- the- top destructive system. They Blow as well as led
acids! Don't try this at home!!!! A hellova surprise! I didn't think they
would DO that? After all, they are a different chemestry? Right? WAS it
hydrogen that blew things up??They run Koh as an electrolite?WHAT is this
stuff? Tastes terrable!But what amazed me was how squeeky CLEAN the plate
assembly was!NO deterioration, no crud in the bottom of the cell, no nasty
shit like that.I have blown up enough Led acids to know what a gloppy,
gooey, mess in them.
I've heard, maybe incorrectly?That to "Rebuild" a Nicad you flush it out,
lovingly, with pure water(Distilled) refill with NEW Koh electrolyte? Makes
sense to me, as the plates and internal fixin's don't SEEM to deteriorate?
Maybe , but not to the untrained eye.So reversing a cell doesn't blow apart
the internals? Reverse to your heart's content? Then do a equilizing charge,
short them DEAD and recharge, and live happily EVer after? Seems the ideal
Newbee, can't murder my first pack, thing?I have some slightly bigger than
the BB600's Alcad, they say on the box.I think they were UPS batteries?
Should be interesting to try some?Guess I should set up a battery testing
lab down celler?Or out in the shed, as they don't care about cold? But I
do.What do you DO with the old Koh? Ya surely don't just dump it down the
drain,or on the ground????
Let me get a few cars up and runn ing around here, then time to
play.Putting my new Impulse 9" motor in the 97 Sentra, just had the adapter
and coupling made. Keeping the clutch, of course. Deciding on what voltage
to run? 6 or 12 volt badd-eries. I sure LOVE J. Wayland's super clean Datsun
fleet. would like to do something thast would stay as clean. Never need
watering, all that.This isn't gunna be a racing car, but a grocery getter
sort of thing, carefree, plugitin, honey, when ya get home, forget it. I
think EV tech is up to this nowadaze?Will probably offer THIS one up for
sale when done?
OK back to Nicads.
Bob

I'm looking into this right now Tony, perhaps there is a manufacturer who 'got
clever' in some way and electrified their autobax, which takes the hydraulic
change aspect out of the equation.
Also under investigation is hte possibility of modifying one of the several
types of CVT fitted in the past 15 years or so...For fitted one to the 'Fiesta'
in the UK over 12 years ago and they're cheap from scrapyards.
As well as that I'm also looking out for an overdrive unit fitted to the older
sports cars, and also the newer and older 4x4's
GKN make an electric overdrive with a 28% ratio reduction, which can be engaged
on the run, it could be helpful, but I'ld sooner look into the CVT idea first,
if anyone has any input on CVT's I'ld love to hear from you....it seems Toyota
and Honda both do electrically operated CVT's, but you need to buy a hybrid
first to get one....
Cheers

With an auto though, you'd get rid of the torque converter, right? This is a
big
source of inefficiency, and is needed just cause the ICE can't stop at idle, I
believe.

Details make all the difference. Some transmissions have great synchronizers,
and are easy to shift clutchless. Others have very poor synchronizers, making
clutchless shifting all but impractical.
Jay and I have Renault LeCars. I agree with him; this particular transmission
works well clutchless. I had a Borg Warner 3-speed transmission in my ComutaVan
(from a Studebaker Lark); it was also quite good, but shifted slower than the
LeCar.
But, I've also driven a Chevy S10 pickup without a clutch. I don't know what
transmission that one had, but it was much harder to shift clutchless.
I think you should drive a sample vehicle with the intended transmission, and
try to shift it clutchless (with its ICE). If you can do it with that heavy ICE
without grinding or excessively slow shifts, it will work even better as an EV
with an electric motor and no flywheel.

I did a lot of clutchless shifting in my '94 S10 before I started my
conversion. It seemed pretty easy, so I'm going clutchless. I'm
finding that there are a lot of changes between the generation 1 and
generation 2 S10s. Maybe synchronizers were one of them. Or maybe it
comes down to how well worn your individual vehicle is.

This is a repost from
http://visforvoltage.org
I've been charging the batteries in Buttercup (4 @ 12V x 17AH) in two
strings of two. (in the background at http://www.austinev.org/evalbum/822)
Four months ago, I started with a set of four new PowerSonic 12018
batteries.
I had set it up so that each 24V charger would be plugged into one half of
the battery pack individually. My hope was that, if there were any
differences between the two chargers, by randomly plugging them in, the
differences would average out. Over time, the chargers were left plugged
into their respective sockets on the pack, and just unplugged from the mains
when I needed to use the scoot.
Four months later, pack voltage falls off after about 4AH of use. After the
voltage falls off, the voltages under load are as follows:
Charger A:
#1 11.8
#2 11.6
Charger B:
#3 8.6
#4 9.2
It sure looks like charger B has cooked the batteries. I can't believe that
two batteries failed at the same time.
I'm doing voltage cutoff measurements right now. I'll "report back" if I
learn anything else.
..... (time passes) ....
By my WattsUp meter, I did capacity tests and charge profile tests. ALL
batteries had lost capacity: Batts #1 & 2 were around 10AH (14AH expected at
given discharge rate), and #3 & 4 were around 4AH, and thus collapsing on
the normal short commute.
In the charge profile, they charged at a constant 1.5A until 28.9V
(14.45/battery), then switched to constant voltage (mostly). When voltage
reached 28.97V (+-.03V) they fell back all the way ... to 28.03V
(14.01V/battery) and held it at that voltage until I stopped measuring at
eight hours. About one full AH more was pumped through the batteries.
Both bricks were within .02 volts of each other. The cutoff voltages are
different than noted in the 2404 literature (SPEC2404S.022701). I checked
the WattsUp against a Fluke voltmeter and was within .03V in the range near
24V.
My Vector "quad charger" floats batteries at 13.1V/cell, with periodic
"float charge" periods of 13.7V (every few hours, for 10 minutes or so).
Right now, I'm not using the Soneil's at all. While the charge rate was
within the published max for PowerSonic batteries, the float voltage was a
few hundredths above maximum.
I have recieved no response from Soneil: their published e-mail address is
not valid, and they have not responded to the "feedback form" I filled out
at their website.
Remaining challenges: 1) Get a response from Soneil, and 2) see if there is
some way I can continue to use the bricks.
I'm just glad I didn't cook a pack of ten...
Disappointed,
Mark

Batteries are probably not "cooked" but sulfated.
You need to charge them more aggressively occasionally. Bring them up
to 15 volts and hold them there for two or three hours. If the
capacity increases on the next cycle, do it again. Keep doing it
until you get no increase in capacity.
You should do an aggressive 15 volt charge like this on a regular
basis. Perhaps once per week if you drive the vehicle every day.
I like to use a timer and a 2 amp, 15 volt Toshiba laptop
power supply for this type charge.

Hi Folk's
Save your money for a >1kHz switching Fet or IGBT controller that operates in
buck converter mode.
The GE SCR controller (EV-1 & EV-100) starts at 50 hertz!
This reflects *all* the pulse current back to the battery which increases I2r
losses and reduces range.l I tried to compensate with a huge choke and 40kuf
worth of buss caps but finally gave up due to the start-up idiosynchronies of
these controllers.
Cheers,
Mark

it does have the 24-48 V control card, so you would have to get a new one of
those. Still, EV-1C controllers are hard to get. I can't be sure because I
don't have the model number, but looking at all mine and the Flight System's
manual, I'd have to say its an EV-1C. For, $20, maybe its worth something.

I took a look. I'm inpressed. Obviouslt the Good Folks at Tesla are
doing something right?They seem to be willing to share the battery tech,
too.
Oh, really? I have a customer who has a friend who has put down one
of the deposits for a Tesla. They have been trying for two months to
get battery info to try to get a battery pack for my customer's
car. They gave up, said no one returns their calls.
Oh, they're ready to LICENSE their battery tech? Let's see, that
means they've found another way to get people to give them money for
something that may or may not work.
Unlike other outfits we all know and love so well. The guy sez Tesla
will only be a niche markeyt. Yeah! Like Henry Ford, around 1909 or so.

Don't hold your breath.
They will do a grocery hauler, too after getting all
those 100 k jobs built. Looks like a raising star in automobiles, tomorrow,
and we will see Tesla trucks, busses, lawnmowers,tracters, Jet skis, Bikes,

I think Alan Greenspan called this "irrational exuberance".
We have seen this very same scenario go by too many times to count,
for the past couple decades: lots of press releases, flashy looking
car, "going to be" in production "soon", taking orders (and
deposits!) now, will revolutionize transportation, yada, yada,
yada. Remember the Segway? It was going to make cars obsolete! And
the tzero, no longer in production. And the Tropica. And the Silver
Volt. And on, and on, and on.
Ho hum. Now, back to your regularly scheduled reality. What, me cynical?

Hi,
After reading this list on and off for almost a year, I
am ready to start planning my first conversion.
I do need lot of help deciding on which car to convert. I have two
options: one weights 2250lbs and has a max gross of 3100lbs and the other
has a 2900lbs empty weight and 1000lbs of payload. Is this 9inch/FB1 motor
territory? or can I get by with a 8 incher?
Second question is accesorys. Both cars are Citroens. They need
a hidraulic pump running for suspension, brakes and steering. An electric
12volt motor spinning at something like an ICE idle is doable? How much
power would something like that eat? I can live without power steering
in the smaller car, but not on the larger one.
Third is airconditioning. Where I live it gets hot in the summer
and A/C is a much welcomed addition. Whats the usual route for that?
Many thanks...

What do you DO with the old Koh? Ya surely don't just dump it down the

Why not dump it down the drain? Isn't Draino KoH?

If there's no traces of cadmium dissolved in it, KOH is safe to dump
down the drain.

Can't argue with that, but Jay's EV (like most of our DC vehicles)
doesn't have regen ;^>
I think he is suggesting that without the additional energy stored in
the rotating mass of the flywheel/clutch assembly, the vehicle
decelerates more quickly. My observation is merely that there is even
less kinetic energy to dissipate if one disengages the clutch so that
only the energy stored in the rotating mass of the clutch disk need be
dissipated.
FWIW, my driving style is to anticipate traffic lights and stop signs,
etc. and to coast toward them such that as often as possible I don't
have to come to a complete stop, so I consider the additional energy
storage of the clutch and flywheel to be desirable in my EV.
Cheers,
Roger.

Hi Eduardo, and welcome to the list.
My Honda Civic started as 2220 lbs, and after
batteries is 3330. I can assure you that 9" motor is
fine, as I'm running 144V on an 8" motor with the
weight listed.
I use a sunroof, and allow convection to do the work.
No air conditioning for me anymore, as it would
decrease my range twice: once by pulling needed drive
current, and the second time, by mounting the
compressor. It would eliminate at least the space of
one battery, if not more.
Hope that helps.

I've got a 63 chevy nova, and I'm working out the details
for the conversion. I've been reading about direct drive, and
everything I've read thus far points to this being the best and
most efficient way to go.
My question is this: Why, if direct drive is so good, aren't more
people doing it? Most conversions that I've read about, people
keep their transmission on in one way or another.
Thank you,
Jordan

First of all, I'm going to assume by direct drive you mean a 'fixed ratio
reduction' and not 'wheel connected directly to motor shaft'
The wheel connected directly to motor requires a motor with huge torque
and low RPMs which roughly translates to 'enormous ammounts of money'.
So, assuming a fixed ratio reduction:
Are you planning on drag racing this vehicle? Or are you planning on
using an AC or brushless DC motor?
If the answer to all of these questions is no, then direct drive is
probably NOT the best /nor/ the most efficient way to go.
A fixed reduction setup requires either a very high reving motor and
usually a high voltage pack connected to a high reduction, say 10:1. This
usually means an AC or brushless DC motor so that it can handle the high
RPMs. WHile not as expensive as they used to be, this still tends to be
somewhat more expensive than the commonly used series wound brushed DC
motor. And you usually have to add an expensive, custom, transmission.
THe other way to do this requires either one very large brushed DC motor,
or two smaller motors, that can handle large amounts of current and
produce huge amounts of torque and a lower ratio reduction, perhaps 4:1.
This also means that you need to have a controller that can handle huge
amounts of current.
This is a very expensive option since the controller is about twice as
expensive and the motor is either more expensive (one large motor) or
twice as expensive (two motors).
This option is perhaps even more expensive than the AC motor option. It
also tends to be less efficient at low speeds than the more common option
using a multispeed transmission.
So the reason they aren't more common is because they are almost always
more expensive, and the efficiency advantage is somewhere between small
and non-existent.
Oh yeah, the reason I mentioned drag racing is because these folks already
use large, or multiple, motors and powerfull controllers and the
transmissions usually end up being the weak link and breaking on them.
