I just went on surpluscenter.com and found a bunch of motors that could
easily drive the cars AC compressor off of 24 or 12V. That might be a very
easy way of doing it. Have the motor run the AC and Power steering pump and
be able to select the AC compressor exactly the way it does on the gas car
with the electric clutch. You could turn off the motor if the AC was off
and you were driving to conserve juice. Then run the AC and power steering
motor off of two or 4 Trojan 400AH forklift batteries instead of the pack
voltage - charge them separately so they will not affect range of the
vehicle at all other than the added weight of those huge batteries.

Subject: Re: air conditioning for ev's
I have also been thinking about how I am gonna do AC, I have teh
compressor but I put batteries where the condensor was :-(
I plan to try 1 liter coke bottles one set in the freezer at work and
one set int the freazer at home and an icechest setting in the passenger
seat until I can find a 2004+ prius AC compressor. It runs near pack
voltage(I'll want a controller) and is very efficient. I will then
relocate the condensor to the area where the fuel tank was and put an
electric fan and a really good grill on it. These must be coke bottles
not pepsi because the coke bottles have the shape to allow air passage. :-)

Hi Andrew,
I bench tested the module with a 600V power supply. It did not require
power cycling to come back on after going below the under-voltage point.
According to the data sheet it looks like the module has an auto-restart
feature. It checks every 2-20ms and restarts when the "fault" has been
cleared.
I don't have any other experience with Vicor modules so I can't comment on
if other modules do this. I ran the unit both below the under-voltage and
over-voltage and did not reset power in between, it always restarted on its
own.
Regards,
Chris Brune

Hello Mike & Paula
Here is some one liners deride from the following logid:
A EV is a voltage machine so from EMF:
Electro Motive Force
A EV provides a magnetic force field so from MAD:

or

Subject: Need Help Quick on EV Poster
I was contacted by the planners for the Alaska Renewable Energy Fair to
review and make recommendations for their poster highlighting EV's. They
are making one for each type of alternatively powered vehicles. The EV
poster seems ho-hum. Except for the picture of my truck its not very
informative and may be counter productive. Does anyone have, or has
anyone seen a good "one size fits all" poster advertising Electric
Vehicles. I'm working on some good "one liners" to highlight all the
important aspects and will proactively re-design the poster and present it
back to them for review. I think they plan to use high quality printing
and mounting to rigid posterboard for their display. So good pics, and
good statistical one liners would be helpful. I will build a poster
myself to recommend to them but if someone has already done an excellent
one I would like to borrow it for the show.
Thanks for any input.

Hi Dave,
I only made one... The modules are pretty expensive, $263 plus shipping.
The Vicor module I used is a V375A15E600BL. I added reverse polarity diodes
on the input and output to protect against an inadvertant mis-wiring. I
also added 2uF of film cap to the input. Output voltage adjustment is done
with some creative use of the scaling resistors feeding the SC pin.
The heatsink/enclosure/connectors were canibalized from a different product.
The data sheet for the Vicor module really has all the information you need
about how to use the module.
If others are interested in having the module put into an enclosure with the
extras that I did for John I can build more, but I'd have to make some money
to cover my time and expenses. Ball park I'd say about $550 each.... All
proceeds more than likely going towards a Zilla.
If you are interested let me know. I would like to get a little feedback
from John before committing to too much at this point. I kind of rushed my
testing because John indicated he would be racing this week.
Also, if the intention is to use this in a car where the draw is more than
20A it will be necessary to add a fan, or rethink the enclosure. This unit
has a significant amount of waste heat.
Also, the unit does draw a significant amount of quiescent current when it
is on (about 30mA). So you need to switch it off when not in use for long
periods of time (like overnight?).

Chris Brune

Hi,
I hope someone who can make it on Friday can get some pictures of the
mounting location. John always does a clean and professional job of
mounting the electronics in his cars.
If someone does get a picture please post somewhere. I didn't actually get
a chance to take any pictures of the outside of the unit. I took several of
the inside so I would remember what I did. ;-)

Yeah, I saw that in the archives, anyone tried one, certainly the right
price. So it seems not much if anything available on the used/surplus
large DC motor market.
Here is something, on sale only $465 :)
http://www.electricmotorwholesale.com/index.cfm?fuseaction=catalog.prodInfo&productID=68&categoryID=54
Now just need to figure out how to generate three-phase 230vac..
Now i'm thinking let's do this real simple, and use a 460v DC battery
pack. With 4v lithiums, thats only 115 cells. Seems to defy the point of
using AC vs DC, but my gosh, $3000 AC controllers?

wow that sound really kludgy, although I'd probably try something like
that.. You might look into using thermoelectric (TEC) modules, they are
very power inefficient, but they can produce very cold temps. Me thinks
one could use a TEC to cool water, and pump the cold water through the
existing heater system in a car and get cold air out the vents. The
beauty of the TEC is reverse the polarity, and it will then be a heater,
so you solve two problems at once.

Subject: Re: air conditioning for ev's
The "portable" AC units I have seen are 3-port units. That is, it takes
in cooled air from the room, uses it to cool the condenser, and exhausts
it. It's a horrifically inefficient and ineffective cycle because
somewhere the room has to draw in hot outside air to feed it. It can
actually make the room warmer. In a well sealed room, the pressure will
drop slightly and the condenser fan will simply stop moving air and the
unit stops working.
Window units are 4-port systems, which makes a lot more sense. You
might also be able to modify a "portable" unit to be a 4-port.
You need quite a few BTUs to be "adequate". I'm not clear on how many
BTU it takes to equal a normal sedan's system but I think it's something
like 10k BTU.

Yo Dude!!
Wayland's Ricer Tin Can don't weigh 5000 lbs !!!
The Gone Postal with 40 40 lbs batteries....needs all the help it can get,
and 5 gears and series parallel are all we can find without buying a couple
of Ford 9 inch rear ends.
So... Direct drive is not a good idea, We need the fronts to get us moving..
then we let the S/P rears suck some watts, and warp 1 comes by in a hurry.
God Rod don't break it!!! please!

Thought about that but was going to go the other way embed the TEC in the
heater housing where the AC coils would be and then pump the heat out via
water block. Was looking at about 10 modules first crack. But... Need to get
the car rolling first before I worry about accessories like AC, steering,
and breaks ;)

Not the ultimate ways to cut, but if you aren't cutting much they
make good use of stuff you might already have:
Put a metal cutting wheel into a circular saw. If you have an
electric miter saw (sometimes called a "chop saw"), even better.
For a little cut, a cutting wheel on an air compressor grinder works.

The 2 EVs are:
1) a '93 Skoda 5 door hatchback, originally 84V with 14 6V flooded
batteries, now with a 96V hybrid battery pack consisting of 28 cells 100
A-hr Thunder Sky Lithium ion and 8 Interstate DCS-75 12V AGM batteries. It
has for now a 4.5kw roof-rack mounted generator: eCycle MG30 PM BLDC &
3-phase bridge and Honda 6.5HP GX-200 electric start engine. This generator
will be replaced soon by a 5kw one better matching the increased pack
voltage, made with an eCycle MGA-2-36 and Robin Subaru EX-21 7HP OHC engine.
(weighs about 70 pounds, dimensions about 14" x 16" x 14"H.)
2) a '94 Skoda mini-pickup, battery pack just recently changed to 11 of
4-DM-146 8V sealed AGM, for 88V nominal. These are part of a shipment of
6V and 8V golf cart size AGM batteries that I imported from Sacred Sun,
China, for evaluation for future distribution. It has a 12V "turbo boost"
that adds 12V to the battery pack by a SPDT contactor (and protection diode
for the NC contact) switching in a 12V battery for extra acceleration and
speed briefly without shifting. The 14kw generator mounted underneath in
the back is an eCycle MGA-3-36, with 210Amp 3-phase bridge and driven by a
Honda 24HP GX-670 V-twin electric start engine. (weighs about 150 pounds,
dimensions about 18" cube)
I am the eCycle distributor for their products for Canada and for EV range
extender uses for anywhere, and build generators for EVs (and renewable
Energy systems) to order.

Doug

My bet is that meter looks for the ignition noise on the electrical bus
(every time you hit the ignition coil it radiates noise back through the
electrical system). You could recreate this but it would be easiser to crack
open the meter and tap off the input filter and supply a real tach sensor
input to it.

Any GTech users out there? The factory claims no EV experience. The meter
is designed to work off of alternator noise, so they surmised that a big EV
motor would put out similar noise, but since that is isolated from the 12V
system, I wonder... The meter is apparently not compatible with a
standard magnetic tach sensor.
No EV experience....?! Would one of you noteworthies would like some help

There is a calibration issue. Battery power is 100 kW at 3500 RPM but motor
power is 150 kW. The error tracks throughout the data with motor power being
50% more than the battery power. I don't believe you have an overunity
controller. Put another meter on the battery to see if the indicated current
matches the recorded output. When you know the scale factor, you can apply
it to the recorded data to reconcile the results.
