These "don't have tabs" which will make connecting them more difficult.
I ordered one for testing but I believe I damaged it while attempting
to connect a wire (since it doesn't have a tab). By the time I got a
change to cycle it it was not performing very well. I only get about
1/10th their capacity out at 1C-2C, though this could be due to my
having damaged the cell. Anyway, If anyone is still interested in
experimenting with them I'de get one or two and test it first. I may
get another one myself and see what they do before wrecking it.

As far as I know, the "best" CVT is the 300zx one made from 2 half
spheres a driver and a driven and 2 rollers on an axle that can have
it's angle changed. The pressure on the 2 spheres and the special gear
oil make the metal on metal contact non-slip. {"best" = least loss}
http://www.histomobile.com/histomob/tech/2/90.htm
The Murano has a "push belt"
http://www.canadiandriver.com/articles/jk/030402.htm
The snowmobile (salsbury? ) unit is wasteful and most belt units are too.
We have a great little transmission shop here in town, If we could
figure out what people would want, I think we could develop our own
transmission using standard "guts" that mounts directly to the C-face
of the 9" motor or 8:" motor and provides a driveline out For front
wheel drives we just need to use an adapter that comes off from the side
American style : engine offset, tranny underneath with hollow setup
allowing left and right axle shafts
Import setup : engine inline with tranny, crown and pinion drops down
to provide left and right.
I saw some units like this on Victors site
What would we want 2,3,4 speeds? reverse? , internal clutch? solinoid
control vs lever control. Some kind of universal control like paddles on
steering wheel so we don't have to mess with shifter location or a
encoder from a stock automatic shifter cable?
How much should it weight and how much torque should it handle (allowing
3X torque electric over ICE because of no torque ripple)
The planetarys are being replaced in racing with the G-force style or
Liberty clutchless, They say the clutch is for the launch only and that
all subsequent shifts are at full power without clutch. Since our engine
RPM is 0 at a stop, they do sound ideal. Sneaky, it is a dog box with
the driver dogs split in half and seperated by springs. When you shift
it engages one side of the dog in the gear and the speed of the other
gear throws the other half out. I may be suspicious, but I don't see
mention of downshifting.

You are correct Lee, most of the PC power supplies are junk, but I got
so tired of them heating up my room and failing and being noisy that I
finally got one of the ones appoved for europe (where the standards are
a lot higher).
The cheap ones also are rated at their peak power output for efficiency
and really waste power when they are not producing power, Their minimum
output is quite high.
I said "some newer" , I should of said "premium" . On these exceptions,
how hard would it be to change the output regulator to regulate to 15V
instead of 12. I haven't looked inside this one yet so I don't know what
type of reference they are using, if it is digital Voltage to Frequency
conversion and a counter that is internal to some chip, imposible, but
if it is just an opto-feedback or zener reference, we could bias it up a
tad.
This one claims MTBF 80,000 hours, regulation on +5 +12(1) +12(2) +3.3
-12 +5(2) of +/- 3%
dedicated outputs, accurate ratings, Active PFC
here is the beast. It is quieter than the processor fan and this 3200
64bit machine now heats up the room less than the previous 1600 32bit
machine.
http://www.antec.com/us/productDetails.php?ProdID=24480
What intriqed me with this idea is perhaps the wide range of input
voltages, A lot of the DC-DC's mentioned have been so limited in input
range that i have heard concerns that they will shut down during use and
fry during charge.
I have a vicor module 330V in(780W) and 13.5 v out(675W) (VI-910116,
01990706123618, 27005243) that I had planned on using but from what I
found out, it is just a module and needs more circutry. PS I was
considering your battery balancer, would this "gen 2, maxi" vicor module
work with your board? I was still a little foggy on how i would use 25
batteries with your balancer; except to use the battery box heater as a
bank select and addmore 1 of 10 decoder chips and opto isolators with a
daughter board

IN a battery box with an inch of urethane insulation on 5 sides,
0.1W/lb, or about 0.2W/kg will work down to 0F, or so. I don't recall
exactly how fast, but I think 2 degrees F per hour or so was what I
remember with heaters on full tilt on the lead battery boxes I built.
But that is sort of picking a trend out of the noise with NTC
temperature sensors on battery posts.

The batteries have so much thermal mass that they only heat/cool

5 deg.F per day. So a couple days at 100 deg.F might warm them from 70
deg.F to 80 deg.F.

Bill,
I have a good condition original 216V G-Van charger for sale. It is a
weather sealed outdoor style industrial duty Chloride Charger. It is located
in Phx and I am looking to get $1,350.00 out of it. Note this is a large and
heavy industrial charging station, not an onboard charger. Let me know if
you are interested and I will be glad to e-mail you the specs and picture.

It looks kinda similar to the GE aircraft starter/generators and generators
used by a lot of early EVers. If you figure out what the Ebay motor is and
find that a starter/gen would do, I have a couple of the GE CM-72 or 74
(IIRC, I will have to check) that I would let go for a lot less than what
they are selling that kit for. I also have a Corbin VW adapter plate that
was going to go on the TP if you need one of those.

TdS Report #34: Team Profile: Hybrid Attack
The West Philadelphia High School Electric Vehicle Team is returning
for its fifth Tour de Sol. Previous entries were a foundly remembered electric
Saturn and a hybrid Jeep, still in use. This year's entry is turning heads! I
spoke with Devereaux Knight, the team captain and a senior in the club.
"It's a K1-Attack kit car from Slovakia. It is the first one imported to the
United States, which they donated to us. We told them we were going to make a
hybrid for the competition. They thought that would be good publicity. We
gave them the carbon fiber the body and they made the parts." It arrived in
the summer of 2003.
Often kit cars are bodies that are put on chassis from production vehicles.
But not in this case. The chassis is a custom tubular steel frame welded up
for the car.
The body in front is hinged below the bumper and tilts forward to expose the
electric motor and controller. "It's a 200 horsepower AC propulsion motor with
a Honda transmission that drives the front wheels. In the back we have a turbo
diesel Volkswagen TDi engine that drives the rear wheels. We aren't running
the electric motor yet. We ran into some problems with the battery box and ran
out of time." They were supposed to go in the side of the car, but they are
going to redo them when they get back after the race.
So the car is being entered as a biodiesel. It has been running since January
using B100, the pure stuff, which is made from waste oil "from McDonalds. We
get it from a company that makes it from used vegetable oils."
The car has two really deep bucket seats with five point seat harnesses. The
instrument panel is from a Volkswagen.
The car has been getting some community interest. "The Daily News came up
yesterday, Channel 6 did a segment on us, and West Side Week, a West Philly
newspaper, also talked with us." Is it a chick magnet? "Oh yeah. When we are
driving it around a couple of blocks, it's `Oh, can I get a ride?'"
But sometimes the attention makes you nervous. Like the guy on the highway,
driving alone, who pulled up along side the trailer and first took a few
snapshots and then was shooting with a video camera, all at 65 mph.
When I asked if there was anything I forgot to ask, Simon Hauger, physics
teacher and team supervisor, chimed in, "Top speed of the vehicle." So, how
fast have you gone? "I've never broken the speed limit, 65 miles per hour."
I asked Simon how this came about. "We have a summer program where the kids
lay out their projects for the upcoming school year. The kids had seen that
the hybrids in the competition and the one they had built were not getting the
type of attention that they should." Two summers ago they came up with the
idea of building a fast, cool hybrid that got great gas milage. Sexy and
ecological too. "It seemed a bit lofty at the time, when we started sending
out donation requests. But materials started coming inand the kit-car company
donated the kit. And so we got committed."
Ron Preiss teaches auto shop, and responded to the question if these projects
teach applicable skills. "Does this apply? Absolutely! This is our future.
This is what these kids are going to be working on. The suspension is ultra
high-tech. The drive chain is something we'll see all over the place. It is
what the kids should be learning about. They are doing things that guys out
there 20 years have never done. It brings math and science and automotive all
together and they understand why they need to know all these academic
subjects."

TdS Report #35: Interview: Craig Van Batenburg
Craig Van Batenburg created the Automotive Career Development Center, ACDC for
short, which is a "hybrid training resource company. We opened in 1998 to help
the state of Massachusetts with it's emissions training program, which we still
do.
He owns a Honda Insight Hybrid with serial number 157, built in December 1999.
"I ordered in June 1999. I went to my local dealer with a check and said, `I
want to buy a Honda Insight.' When they asked what is that, I said I would pay
retail. So they gave me a receipt.
"As you can see it's in perfect shape because it is all aluminum and the winter
has not done much to it. With snow tires this car is fabulous in the snow.
I put it into a lower gear, so the electric motor does more of the work. It
has so much torque down low that it doesn't spin the tires.
"What I do is train independant service technicians how to work on hybrids, so
consumers have an option between the dealership and an independant shop.
That's my full time charge. I have all the books, scan tools and equipment
needed. For 26 years I ran an independant repair shop fixing Hondas and
Toyotas. Our focus now is environmentally clean transportation. We are trying
to get technicians, who influence a lot of people's buying decissions, to not
only work on them but to drive them. We have some of my buddies are part of
the Monte Carlo Rally. They bought Insights on eBay and are driving this way.
Both owners of Slipstream Automotive in Boulder Colorado are coming. They fell
in love with this after they came to my hybrid class about 4 months ago. They
got bit by the bug."
He says there are tons of information on the web site. Links, cool pictures,
everything. There is also a CD-rom that is a 112 page booklet for consumers
and technicians. "It's a version of a manual I wrote for hybrid technicians
turned into a consumer's manual. If you are a hybrid owner and want to
understand how it works under the hood, this is what you want, with pictures,
diagrams, and explanations. There are also helpful hints for talking with an
independent repair shop. The cost of the CD is $29.95 plus $3 shipping and
handling; $5 goes to NESEA. You may print the manual once. Any time it is
printed after that, we ask that they send NESEA $5, on the honor system."
http://www.auto-careers.org
Craig told an interesting story about the new Honda Accord Hybrid. That car
has 6 cylinders, but runs on only 3 cylinders when cruising at 60 miles per
hour. "I can get 35, maybe 36, miles per gallon on 3 cylinders." But it is a
powerful car, so it can easily drive faster. "But when everyone is going 75
mph, my temptation is to do that too. But then there is so much wind drag at
that speed (drag goes up as the square of speed) that the 6 cylinders have to
kick in. You go from 36 to 27 mpg in a heartbeat. So the 3-cylinder mode is
only for people who have more self control than I do."

I have to say that seen class F (150C) insulation run above rated temp
for days without a failure. When the air exiting the motor is above
150C (about 300F), it smells a lot. So a little stink probably isn't
too bad for the insulation. What is happenning to the commutator, I
don't know. That may be different. I was working on motors without
commutators.

Most EV motors and forklift motors have class H
insulation (that's 180 degrees Celsius).
If you have a thermocouple mounted IN the winding I
wouldn't go above 150C.
Measuring temperature anywhere besides the brush or
winding is somewhat quesswork since it takes awhile
for the temp to propogate from those locations,
especially under heavy load conditions (lots of big
hills).
You could also mount a sniffer tube :-). You'll smell
those windings cooking before you really do major
damage in most cases.

Subject: Motor Temp (was Re: An update regarding my
JeepEV)
Hi,
The motor in my Jeep has been reaching 140 degrees
F after ~16 miles of
driving at speeds between 35 and 50 MPH. I
measured this temperature by
sticking the temp. probe into the threaded hole in
my motor's tail shaft.
Quick question: What is the maximum safe
temperature a 9" ADC motor
should be allowed to reach and what would be the
first thing to be
damaged if the motor gets too hot (insulation on
the windings maybe?)
The temperature in the tailshaft hole doesn't
matter. Temperature of the
armature and field windings matter as does the
temperature of the brushes.
Several on this list including me have measured
brush temperature with a
thermocouple imbedded in one of the brushes. Brush
temperature is an
approximate indication of armature winding
temperature because heat in
the windings is conducted thermally to the commuator
and to the brushes.
I recall some discussion about allowable maximum
brush temperature on
this list but I don't recall any meeting of the
minds on allowable maximums.

Those 99 cent cells look like quite a deal, but without the tabs, they're more
trouble than they're worth. If you can handle paying almost 3 times as much per
kwh, you can choose a soldering tab option with these -
http://www.batteryspace.com/index.asp?PageAction=VIEWPROD&ProdID=990&SSAID=101861
(oddly enough, better volume discount from the same folks here:
http://www.batteryspace.com/index.asp?PageAction=VIEWPROD&ProdID=989&SSAID=101861).
After opening plenty of dead laptop packs, I can say the BMS doesn't cover
individual cells but the paralleled "buddies", whether 2, 3 or 4, and rarely
did these sections have single cells die - better than 90% of the deaths
involved the whole section. A 1C load test on each cell to get similar
capabilities, then just monitor each 3.6V (or 3.7V) section. The 2.5C max on
the above cells either limits your peak current or neccessitates a really large
Ahr pack.

I've used the Vicor VI-200 series 200w modules as boosters, but not one
rated at 150w. The specific ones I used were 36vdc in, 12vdc out. I've
also used the Batmod variant as a booster. Neither of them made any
acoustic noise that I can recall.

The ones I have disassembled used a TL431 as the voltage reference, and
it only monitored the 5v/3.3v output. They only regulated it; the 12v
output and the rest were either completely unregulated, or had a
3-terminal linear regulator (for output rated at low currents).
If you're willing to trace out the circuitry, you can probably remove
the resistor that connects the TL431 to the 5v output, and connect a new
value to the 12v output so it will regulate it. By choosing the value of
this resistor, you can change it to 13.5v or whatever. Beware of the
voltage ratings of the filter capacitors on the 12v output! They may
have used only 15v or 16v parts.
> This one claims MTBF 80,000 hours
Those are calculated, not real. They all use electrolytics which are
only good for a few thousand hours of operation before they go out of
spec. In most cases, they have sized the electrolytics so they operate
right at the limits of their voltage, temperature, and ripple current
ratings. Thus they don't have to degrade very much before they will be
over ratings and fail.

The on-board layout is set up to use a Vicor Batmod, which has internal
voltage- and current-regulation, and is specifically built as a battery
charger. You could add some control circuitry to your module to
accomplish the same function. Or, the board is set up so you can use any
external DC/DC you like.

Either of these methods works. The basic board is set up for up to 15
batteries. There are 3 general-purpose relays. I use one for the front
battery box heater, one for the rear battery box heater, and one to turn
the bulk charger on/off. If you have more than 15 batteries, use a
second bank of 15 relay, and use one of the general-purpose relays to
select one bank or the other; this gets you to 30 batteries. Using a
second general-purpose relay can double this again to 60 batteries.

Hello List,
This is my first list email, so be gentle :-)
I tried searching for the data I need using mail archive, but was
unsuccessful.
I recently purchased my first
EV, Jim Coate's 92 S-10 EV <Woo hoo>. I just purchased 22
of the Sam's Stowaway batteries, the pack in the truck was pretty much
toast.
I wanted to sanity check what I was getting ready
to attempt, and see if anybody can offer any pointers:
I have a PFC-20 and I am assuming the pack
should read about 138.6 volts when charged (22 x 6.3 = 138.6). Checking
all the batteries individually with a volt meter showed voltages from
6.23-6.28. I have an older PFC-20 charger, I was going to hook the pack up
and configure the charger using the instructions on the Manzanita Micro download
page.
Any hints / tips / suggestions?
Thank you,
Glenn Young

Thanks
I have one of those. It is pretty primitive and very large. There is
no way I know of to modulate the charge current. It is ok for flooded
batteries, I am using AGM's with Rudman regulators. I am looking for an
inboard charger that I can set up to work with the typical conductive
charge station(forgot the name of it).
On the other hand do you have any info on the vans? I have some manuals
from Chloride but nothing with too much info.
The charger I have needs some help, I have to make the relays close to
get power out of it.
Thanks Bill

Bill,
I have a good condition original 216V G-Van charger for sale. It is a
weather sealed outdoor style industrial duty Chloride Charger. It is
located
in Phx and I am looking to get $1,350.00 out of it. Note this is a large
and
heavy industrial charging station, not an onboard charger. Let me know
if
you are interested and I will be glad to e-mail you the specs and
picture.

And so you're saying you did what (?) with the sense leads of the drivers to
make them act as boosters? And what about the TRIM lead? Left them all
just hanging open?
The devil is in the details.

Read them through, and if you have any questions...
That's what I am here for.
I am trying to keep them short and sweet.

Sounds like it's a working unit.
Still where's the lid??
