1. It might help to identify where this meeting will be. I have no
   idea where "WPI" might be.

2. The "Impact" EV was built for GM (General Motors), not GE (General
   Electric).

3. The Impact is not the "first modern electric car". General Motors
   own 1966 "Electrovair" EVs had the same 3-phase AC solid-state
   inverter, oil-cooled induction motor, single-speed transaxle, high
   voltage battery pack, etc. Its size, weight, range, and top speed
   were virtually identical to the Impact and lead-acid EV1.

The CitiCar, ComutaCar, and ComutaVan all used H-B brand contactors. H-B
was bought out by Prestolite. These same contactors have been sold for
something like 40 years now. They have replaceable contacts, and it
should be no problem at all to get parts for them at any place that
sells parts or services golf carts.

Sure, this is a great use for the EV list.

Remember that this type of switching power supply is a constant-voltage
power supply, not a battery charger. You may find it to be hard on your
battery, especially if left on a long time. You may also find that if
the battery is too deeply discharged, the power supply won't be able to
start charging it -- it will immediately shutdown due to over-current.

Get them quick though, Rod is going to buy half of the stock:-) Lee, the battery pack will be flooded nicad and I have manufacturer documentation that says CV is an acceptable way to charge them. Hopefully I won't run into an issue with over-current shutdowns, I will cross that bridge if I reach it.

The good "POP!" and shower of sparks was my first experience with
my Todd 75A unit when I went to hook it up to a 12V battery (I
have (did, actually)) this unit on my deck charging batteries,
not in my car.  Fortunately, hooking up through Anderson SB-50
contacts solves this problem.  The AC plug-in can also result in
a pretty good snap.  My practise for most of the Todd's life has
been to plug in the AC side first, let everything get built up in
the caps, then hook up the DC.

Unfortunately, my Todd is somewhat unhappy, as I hear many of
them are out there.  I think mine, though, may be better off than
many.  The DC voltage is unstable.  If everything is hunky-dory,
if I crank the pot fully clockwise, I'll get ~16.40V unloaded,
staying that way for any number of days.  However, what started
happening a couple of years ago is that this voltage would start
to drift, moving the whole range of the pot adjustment up and
down.  I could usually get the voltage back up by doing a
"conditioning" ;-> run, running the charger into a resistor, at
say either 40A or 70A, depending on how gung-ho I was.  After
half an hour or so of this, the charger would be noticeably
warmer (fan running), and the voltage would be back up.  Checked
the pot, and it appears within spec (ohms inverse of voltage -
250 to 0 ohms).  It appears that to pull the circuit boards out
of the charger is rather a bear, with lots of wires, and what
looks like (ground?) hooks at the bottom of the cards.  Also have
been told that this maybe a cap problem, or perhaps a circuit
trace thermal problem (which I may or may not find after taking
this puppy apart, hopefully without destroying it).  I'm told
that there has been some discussion of Todd problems on this
list, but still have to go diggin', and maybe there is some stuff
out on the internet.  Anybody on the list with connections or
knowledge of Todd repairs?

Hi Ken,

On my car, back behind the speedometer (and you could probably
see them from under the dash), there were two white cube-like
objects with slots that wire tabs go into.  I had to jumper two
of these together with a single wire.  I did this reluctantly
after carefully studying the wiring diagrams and not seeing any
other way to do it.  It certainly got the fan going with no arcs
or sparks or blown fuses.  I took a picture of this arrangement,
which while I don't have a scanner handy, I could probably get an
image copy made and either post it on the internet or send it to
you, if it would help.

Maybe the strongest Loctite would suffice to keep that shaft

I'd bet that power steering would also be nice :-) in a car with
a 1400-lb pack!  Don't know if you have that in your car, but
some people power that off the motor, although it's probably
better done with a separate electric motor.

Well, the rears (which probably don't do much for panic stops,
but it's nice to be able to stop the car with the emergency brake
on my hill if I had to) are carbon-kevlar linings and shoes that
you can order (or at least used to be able to) from Porterfield
(if you want the number I can dig the catalog out).  The person
who helped me convert the car helped me put in those
shoes/linings.  Front ones are vented rotors and semi-metallic
"rotor-eater" pads that my mechanic put in for me.  I had been
angling to get carbon-kevlars up front too, but my car was in the
shop for some other work, and apparently I hadn't been watching
the old organic linings closely enough, and was just about down
to the rivets on the organic linings on the inside shoes.  They
weren't really wanting to let me out of the shop without getting
the brakes dealt with, and after some humming and hawing, I got
the current stuff on the front.  Only thing I notice is that the
fronts take just a bit of warm-up, which ain't far going down my
hill - takes only a few feet, and you can feel those linings
start grabbing.

--- Begin Message --- I used some of the Pipe Heating cable that Lee mentioned. I bought a 100' roll from DoitBest.Com for $158.
This stuff seems to be working pretty well. It's been keeping the battery compartment at about 68 deg F even when it was 30 outside.
Since I couldn't figure out a good way to hold the cable to the batteries, I made heating pads that I put under the batteries. This consists of a piece of 1/4" thick plywood, with a 3/8" wide, 3/16" deep groove for the cable spiraling across the surface of the board. (routers are very useful!)
I made a board for each cluster of batteries, and wire them all together. Seems to draw about .7 A from 120VAC after it's all warmed up. Draws a bit over 1 A when plugged in with a cold pack.
I'll try to post some pictures soon.

--- Begin Message --- This is a very important point that I didn't mention
in my post about using it for the scooter.
The power supply should be current and voltage limited,
but not for charging a battery.
I use my extra TEVan charger for pumping 55 amps into
my golf cart. It's current limited, but it would keep on
dumping 55 amps since the voltage won't go above 68V on my 48V
golf cart. This sounds like high voltage for a 48V system, but
the NiCd's (SAFT STM-180) spike up quite high above 90% charge
with high current. I 'babysit' this charger setup and shut it down
soon after seeing the high voltage rise. Same with the sealed batteries
in the scooter. I only plan on using it for opportunity charging though. If you plan on using it for a full charge, plan on being
a babysitter :-)

I have been looking for a couple of switchmode power supplies to use
as a battery charger for my moped.  Well, I found some at an
incredible price and have to pass this one along.  250W for $8.  They
are rated at 24V, but adjusting the trim pot on the board I can get
from 20-27V out.  <http://www.excess-solutions.com/POWERSUP.HTM>
Search for ES2651.  I hope this is an acceptable use of the list.

Sure, this is a great use for the EV list.

Remember that this type of switching power supply is a constant-voltage
power supply, not a battery charger. You may find it to be hard on your
battery, especially if left on a long time. You may also find that if
the battery is too deeply discharged, the power supply won't be able to
start charging it -- it will immediately shutdown due to over-current.

Ok, I've tried Uve's EV calculator and I give up. It talks about a bunch of stuff that I just don't know and gives numbers that don't make much sense to me.

I'm trying to determine what kind of performance and range I can expect from a conversion with these specs:

Glider curb weight: 1300 lbs.
Glider engine weight: ~150 lbs.
Glider wheels/tires: 145-R10 (possibly switching to a more standard 13" size)
Batteries: 156V Optima YT (possibly 156V NiZn with SVR booster?)
Motor: WarP 9"
Controller: Raptor 1200
Tranny Gearing: 1st: 2.47
2nd: 1.565
3rd: 0.967
4th: 0.675
FD: 3.739
Charger: PFC-20 (if not a PFC-50)
Frontal Area: A not-very-aero 12 sq.ft. (width x height is what we're looking for, right?)
Estimated Total Weight: 2100 lbs.

Am I missing anything important? What kind of seat-of-the-pants performance do you guys think I'll get with this setup? Both with NiZn/SVR batteries or Optimas?

I'm not trying to farm out difficult math to anyone else, I'm just looking for educated guesses.

Thanks!

I'm reading all this and wonder why people go through
as much trouble as re-machining the motor shaft, put pulleys
and belts running the vac pumps, if electric vac pumps do it 
for far less money, space, power losses and can be mounted
anywhere?

Just for love of tinkering? Just curious.

Ok, so thanks to Steve B. (of Tropica fame) I have a very nice Bradley
body to begin my next EV project.  So a question to you VW aficianados
out there:
The Bradley is made for the pre-Super Beetle VW pan...are there
arguments in favor of going for IRS (independent rear suspension) years
rather than swing-axle years?  What about upgrading brakes to disc?
Any related thoughts on what to look for in a donor vehicle?
What about running gear for a fairly high-performance EV?
Any thoughts based on experience are appreciated!

Some fans will benefit if a capacitor is put across the fan leads.
I've set up my Regs this way, and they seem to work. The regs do seem to behave a little differently though, they turn on and off much quicker. Occasionally actually strobing. They also seem to be able to handle several amps continuously - which the Zivan is happy to provide....

The inertia of the fan and additional load of the motor makes the battery
sag more when the load enables. This makes the battery voltage sag more
aggressively causing the duty cycle to be shorter. This is normal. Don't
worry about it.

--- Begin Message --- Well, I took my Sparrow for another test drive tonight of about 15 miles. Found I have 1 battery that seems to be weak. After the 15.8 mile run it was 11.2v, while all the others were around 12.5v. sigh.
It was really helpful to have the LED's for the MKII"s in the cab, as that is what told me that something may be wrong. Just the one low-volt LED came on. They are currently set for 10v indication.
This kind of puts me out of commission, as I can't make my commute. AAARRGGHHH!!!

I need some Evercells!

You do realize these fans draw something like 120ma? That really doesn't seem significant compared to the reg load.

Michael,

Check out www.bradleygt.com. They have a message board full of knowledgeable folks. 
Tell JeffTroy I said hi. He's the author of the CD I gave you and perhaps the only 
person that purchased a kit directly from Bradley and is still driving it!

take care,
Steve

Bear in mind that Uve's EV calculator is based on 100% DOD. It would be nice
to fact in a realistic DOD to this calc, but my efforts haven't worked thus
far.

For instance, Optima YTs work best with 50%. NiCAD and other deep discharge
can be 80%. Have to factor this in.

I just picked up a nice 88 Toyota ( I think calicos) Its got the blown motor
and I think it would make a nice conversion . got manual tran and looks very
light also its body/inside is in great shape . I didn't see any of these
cars in the album though and was wondering why . title say wt-l-bhp 1905  .
guess that means 1905 lbs ?

I put silicon calk around my potbox (to keep moisture out) and in last 10
years and replaced 2 or 3 . always glad it not the controller ,  the micro
switch goes out every few years also. last one I got from golf Tec here in
Florida had a bigger pot inside .
