Hi Joe,
Rich has it in his shop. We got swamped with orders and have not have time
to put a low voltage load bank together. It has never been charged or
discharged since it arrived.
I can charge it but cannot discharge it yet.
Do you think it needs charged?
Check it's voltage. If it is below 3.75 volts, then it should be charged.
Don't worry about getting it to 4.2 volts. Just get it back to 3.8-4.0 volts
and check it every 6 months.

I found a website for IMP LTD but it was a power
transformer company in Wales. Not a Motor designer.
They were discussing patient infringement yet they
stole another companies name it appears. To bad there
wasn't a website to check it out. Although with the
press miss quoting technical jargon it may be just
over hyped press. After all Brushless motors have
been around for a while and they don't produce arcing
either.

I'm 37 miles away from this one if anyone is really interested and needs me to
take a closer look at anything in person or take other pictures I might be able
to swing a trip up there if I can work it out with the seller.
It looks like you get a motor ("The end bell on the brush end has a crack where
is was dropped by UPS") connected in a pretty ugly way though possibly
perfectly sturdy and aligned to the transmission of a stripped old kia and a
kia manual without a wiring diagram. The batteries, EV wiring (except for two
pieces of 4/0 cable), and controller aren't for sale.

Hi,
My EV reporter friend Bob Wing told me (a few years ago) to visit Inverness
area for the best wind along this beautiful coast for the best method of EV
charging. I went to Denver to the Wind Expo and then (finally) to Inverness
(where Bob lived at Point Reyes Seashore) and was requested to do a report.
I definitely miss Bob.
Mark
Winds of Change
Wind Expo 05, Mark E. Hanson 5/27/05
The Wind Expo in Denver May 15-19th included hundreds of companies, everyone
involved in wind, see www.awea.org for a complete listing and report. There
were mostly conventional 3-prop HAWT's (Horizontal Axis Wind Turbines) and a
few VAWT's (Vertical Axis Wind Turbine's). Randall Swisher, executive
director of AWEA gave an opening speech talking about the status of the 30%
annual growth market but pointed out the boom and bust cycles of the wind
market due to the start and stopping of the wind tax production credits. He
noted that an anti-wind bill was just initiated (by a couple Neanderthals)
this week by Lamar Alexander R-Tenn and John Warner R-VA attempting to
cancel the wind tax credits and keep windmills from being placed off shore,
mountains and other desirable locations. (Call 202-224-3121 and mention that
you do not support the Anti-Wind bill of 05'). It's a NIMBY mentality, but
would they rather have coal smokestacks in their backyards than majestic
silent windmills? I noted. Speaking from Denver, Mr. Swisher noted how wind
friendly Colorado is in putting in the Lamar "Colorado Green Wind Power
Project" which I toured. There are 108 turbines on 12,000 acres on a cattle
ranch where there is a harmonious balance. The rancher I talked to said he
only had to reduce the cattle by one cow of square footage. (He gets $2-3k
per month per wind turbine I was told, 1.5MW each.) Germany, Denmark, Spain
and India are leading the way in wind. After spending a couple days talking
with all the different large and small wind turbine suppliers, I went out to
Lamar which had 108 turbines, not as many as Tehachapi, Cal (>5000) I
visited previously in the year but just as impressive.
We went out to the flat Southwest corner of Colorado to visit a town which
embraced wind. There were windmills (aka small turbines) in many yards and
when we met with the friendly townspeople they were enthusiastic about
getting more silent wind turbines. One rancher noted that his outfit wasn'
t for show,"My boots are for the rattle snakes, my pistol is to shoot the
rattle snakes, and my hat is on since the skies are not cloudy all day".
They get about 10" of rain in Lamar, almost a desert. I stood directly
underneath the wind turbines and went inside the tower and they were silent
revolving at one revolution in two seconds using a doubly fed induction
system which is somewhat variable, but a fairly constant synchronous speed
due to the 60hertz line connections. The blades on the GE (formerly Enron,
formerly Zond Wind-Germany) were variable pitch so as the wind speed
changed; the blades would vary pitch to maintain a relative constant speed.
The GE Turbines are 328 feet high, 1.5MW and the largest manufactured in the
US in Tehachapi, Cal. I noticed that the main control 3-phase 500V - 30kV
converter inside the base of the turbine next to the ABB switchgear was made
in Salem, VA at GE. I was blown away by how silent these wind turbines were
unlike the smaller high speed one I have at home. The technician supervisor
said the controllers were very reliable and the uptime at the wind farm is
in the upper 90's percent. Climbing up the towers to maintain them on a
6-month schedule is hard dangerous work (as mentioned in Renewable Energy
World). I asked him if the technician turnover rate was high like it is in
Tehachapi (around a year). He said it was, and a wind installer I was with
noted that they should have 12 employees for 108 turbines and had 7 working
10 hour days (presumably to save money). I told him they were doing a super
job for renewable energy and to keep up the good work. The Colorado Green
Project produces enough wind-generated electricity to serve about 52,000
average American homes. Each 1.5MW rotor has a 231 feet diameter, 10%
longer than the wingspan of a Boeing 747-400 jumbo jet. When the winds
reach 8mph, the anemometer on the tower and computer sense the speed, orient
the wind turbine into the wind and the blades start rotating. If the wind
becomes to strong, the variable pitch blades turn perpendicular to spill the
wind and prevent damage. It was noted that if the wind comes directly out
of the North, lining up longitudinally with the turbines, every other
turbine must be shut down due to turbulence inflicted from it's spinning
neighbor. The foundations for these monsters go down about 30' and took 294
cubic yards of concrete, or 47,400 tons or 4,741 full truckloads.
Next I flew to Point Reyes National Seashore near Inverness California (from
Sacramento). Bob Wing, an EV pioneer and friend who lived in Inverness told
me that this was the beautiful place to visit and an excellent EV and
renewable energy area. The Point Reyes Rangers there told me that it was
the 2nd windiest place on earth, 130mph winds typical in the winter by the
lighthouse. When I was there a stiff prevailing westerly wind about 30mph
was coming from the sea. They were interested in wind, so I passed along
some brochures on small wind, SW Windpower, Bergey etc. Then I did some
hiking and headed up the coast to stay at Jenner, the town population went
up 3% when I arrived. Northern coastal California is like West Virginia by
the Beach, mountains right down to the ocean. The wind kicked up the surf
causing sneak waves, where you walk along the beach and a wave pops up and
slaps you down, can't outrun it either. I went in but I guess I missed the
"Danger no Swimming" sign. It was nice and quiet in Jenner, I asked about
no TV's and phones and they didn't want to disturb the "spiritual energy
vortex". I had breakfast (broccoli Quiche) I think at Cosmic Charlie's and
headed up to the Redwood National Forest to do some spectacular hiking
around trees at 320 feet as tall as the wind generators. I noticed many
trees along the coast were flagged over indicating average annual winds
20-30mph, great for wind turbines. It reminded me of a 70's Jesse Collin
Young song, "Ridge Top", where he sings about this area, "I live on a
Ridgetop where it's windy and foggy and quiet most all of the time, with
blue-jays and hoot-owls, a 24 hour singing sky", about sums it up.
Heading back from the Redwoods, I stopped at Real Goods, Solar & Wind
equipment distributor in Hopland California. They had a large 115Kw solar
panel array with a 8' x 4' wide 3 phase 208V Trace inverter feeding back
onto the power grid. A windmill was nearby for fun, but not much wind in
the area inland. There was a biodiesel and organic farming demonstrated in
the compound. www.realgoods.com
Will the Wind Tax Credit (PTC Production Tax Credit) set to expire December
of 05 be renewed? The answer is blowin' in the political wind.

I think that for Nickel Cadmium batteries you'd want to test it with potassium
hydroxide, since that's the electrolyte used.
Is nickel the best plating for Nickel Cadmium busbars?
What other materials are potassium hydroxide resistent?

OK will do!
As Joe said... be need to make a Fet based Windloader...er.... product name
for a progammable "Battery" loadbank. We built the first one for SouthWest
windpower years ago.
Coinincidentally... it became the foundation for the PFC50 power stage.
Which are selling faster than I can build them this Spring....
Got IRFZ-48s... I should Rack up a dozzen for Sub 6 volt loads.
And... this might be helpfull on equalizing a 640 Amphour AGM.... for the
Forktruck....

I never had any problem with ground clearance. In general, if there's an
obstacle high enough to risk hitting or high-centering on the battery box,
it's probably something you don't want to be riding over with a heavy
powered skateboard anyway. No grinding the railings on these things. :o)
And in response to Ken, though the wired controller on the e-Glide may be
less of a hassle that I'm imagining, for the record I never experienced
any problems with interference on the eXkate. The point of using a low
frequency and a low-power transmitter (using your body as an antenna) is
to mitigate that sort of problem - from outside sources and other eXkates.
I can't remember where I saw it now, but I saw a video clip a while back
of a couple guys riding together, only a few feet apart. You have to be
standing on the board or right next to it for the controller to work.
One thing's for sure though ... if you're ok with the wire, the e-Glide is
a *much* better deal.

<enough theory and hands-on motor tips to make my head spin>
Even though I get nowhere near enough time to play with my still-not-running
EV, I've been thinking of "next" projects. Like maybe a 156V EM (electric
motorcycle) that could easily become an EM kit based on a popular, available
and reasonably cheap motorcycle. So far (early stages) it looks pretty
good.
Bill Dube (master of hot-rodded ADC 6.7 motors) tells me the mechanical rpm
limit for these is around 7500 rpm. A high rpm limit is very handy when
you're running direct drive. He also says it might be difficult to get that
speed from a K91 (listed at 96V at EVParts) running at "only" 156V.
So, electro-doofus that I am, I'm thinking why not run an A00 motor
(formerly A89), listed at 72V instead? More over-volt means higher rpm,
right? And it would even save me a little weight and length. Of course
just to confuse matters, the A00 has a nameplate rating of only 36V.
Would this work? Running a 72V (36V?) motor on 156V seems a bit extreme.
But then it would be a street bike for everyday use, so most of its life
might actually be closer to 72V. A Z1k should allow the bike to hold its
head up among "real" motorcycles (without threatening any sport bikes). Of
course, I'd probably have to turn the amps down a bit to help keep the front
wheel on the ground when starting out. An external fan for the motor would
probably be needed for around-town work, even if I gear it short enough for
a top speed of only 80 mph up a modest grade. Its range would give it maybe
an hour in mixed riding, or half that on the highway between charges.
Would this be classified as motor abuse? Or controller abuse? (Something
about keeping it in current limit more of the time?) Would low efficiency
eat up my range? (Maybe remove the internal fan, or is over-volting a major
cause of low efficiency in itself?) I realize no one has any hard data on
this. I just want to know if I've gone way off the deep end here, or is
this layout worth testing? If it worked I think it would be a fun ride.

No.
And aluminium is really not a good choice for connecting nicad cells,
if that's what you're planning.
If you want a cheap way to connect these cells, try enamelled copper
strip (transformer or motor winding). Remove the enamel only around
the contact area and completely cover each terminal and strip-end with
petroleum jelly. Just a thought.

Water powered cars is an old idea. When Ford Model Ts were common
you could fill your tank with water, add a special pill to the tank and
run on water. Other water powered schemes have popped up from time
to time. None seem to have made it in the market place.
I won't say this is a hoax because a number of members of this list
fervently believe or want to believe things like this. So, believe it

Unfortunately, anodising forms an insulating layer (at least on
aluminum; not even sure if copper can be anodised).
The terminals/hardware on these batteries appears to be nickel plated
copper, so, as Lee observed, nickel plating the straps is your best
choice for corrosion protection.
> http://www.palminc.com/chemicals/liquid_nickel_sulfate.htm
Note that the product you would want is actually the plating grade (PG)
version of this:
<http://www.palminc.com/chemicals/liquid_nickel_sulfatepg.htm>
and that the smallest quantity you can buy it in is 5gal pails (probably
way more than you need and expensive to ship). Unfortunately, they
don't appear to sell the NiSO4 powder so you can save on shipping costs
and mix it up with your own distilled water.
And finally, it isn't clear (to me) that you can just dunk a part in
this nickel sulfate solution and end up with a nickel plated part.
A better choice would seem to be one of these DIY kits:
DIY nickel electroplating kit:
<http://www.caswellplating.com/kits/nickel.htm>
DIY electroless nickel plating kit:
<http://www.caswellplating.com/kits/electroless.htm>
At anywhere from about $75-150 (plus shipping) depending on the amount
of area you can plate with them, it could work out nearly as cost
effective to have them plated professionally instead.
For instance, John's 1.75" x 0.5" x 1/8" bars, each has a surface area
of 2.3125 sq. inches, neglecting the walls of the through holes for the
moment. Caswell recommends a 1 mil. thick plating for corrosion
resistance, which takes 1hr to plate out, and their standard kit ($150)
can handle a maximum of load of 150 sq. inches (not sure if this is the
total area the kit can plate before you need to buy more chemicals or
just all that the bath can handle at a time). WAGing a total surface
area of 2.5 sq. inches per bar to be conservative, this means a maximum
of 60 bars can be plated in an hour, and if this fully depletes the
plating solution that is a plating cost of $2.50 per bar vs the $1/bar
that John was quoted by a plating shop.
Cheers,
Roger.

You weren't running on water. You were running on acetylene. This is
the same way miner's torches work. A container of water and the
catalyst pellet and gaseous acetylene is produced.

An electrician (& EVer) friend tells me that the type of crimp where the
crimper makes a big dent in one side of the lug (such as a hammer
crimper does) is the recommended/proper crimp for stranded cable.
Despite this, I've done my crimps with QuickCable HexCrimpers because I
much prefer the appearance of hex crimps (or the square crimps of my
smaller (up to 1/0) set of crimpers).

Is there any clearance problems with the batteries hanging under the
deck like that?
Well, with an SLA battery based skateboard, the weight is high enough to
keep you from busting too many tricks. You won't be grinding or hopping
around. That said, it has no problems with speed bumps or most other
road ripples. I've not gouged up the battery box and I've put a lot of
miles on both e-glides and eXkates. It's possible, sure, but I've never
done it.

At 156V if you are under selfdestroying commutator speed there would be no
motor problem BUT seems you will have a BIG problem putting 156V in a
motorbike...lithium ideas ???
120V seems more realistic and already big power with 40Ah, 10C capable
lithium polymer cells assembly :^)

Hi,
I just went looking for a good high-res EV burnout - one from John Wayland or
Rich Rudman would do the trick - but couldn't really find much of anything.
Google searches of the following:
*EV burnouts
*John Wayland burnout
*high-res burnouts
* etc.
..should produce quick results! But they don't.
If anyone has such pictures, I'd be glad to put them on evsource.com or
evgrin.com.
Thanks,
Ryan
P.S. I didn't want to look like an idiot and have someone tell me that the
searches I'd listed really did pull up something. Google result #1 for John
Wayland Burnout brings up John's page on the EV Album. He has a link to a good
high-res burnout photo. Great! Let's put together some more!

My 33Ah SLA wheelchair batteries have the following charging instructions
written on the cases:
Constant Voltage Charging
Standby 13.5 - 13.8
Cycle 14.5 - 14.9
It seems a bit high.
I set my 48V constant voltage charger to 56.8 Volts
(14.2 Volts per single battery.)
14.2 drops in between the two battery uses. It os it too high for standby
and too low for cycle.
Advice please?

And in response to Ken, though the wired controller on the e-Glide may
be less of a hassle that I'm imagining
It is really not a hassle at all. I too thought it would be weird, but
actually it is not limiting (didn't even have to get accustomed to it)
and is actually designed as a safety feature. If you pull your hand
controller off the leash (you fell off the board or something), the
controller detects the disconnect and shuts the board down, braking it
until it stops.
for the record I never experienced any problems with interference on
the eXkate. The point of using a low frequency and a low-power
transmitter (using your body as an antenna) is to mitigate that sort of
problem - from outside sources and other eXkates.
Glad you haven't. The Sony designed eXkate controller is very good for a
wireless rig, but I have had reports of problems with things like
underground power feeds that are near enough to the surface to interfere
as well as high power emergency services radios being keyed up nearby
causing problems. Problems reported were unexpected runaway or full
regen braking. These are VERY rare occurances to be sure, but it does
seem to be possible.
One thing's for sure though ... if you're ok with the wire, the
e-Glide is a *much* better deal.
Yeah, it sure is. Less than half the price.
Have you seen the new low cost eXkates coming over from China, the
"raptor"? I examined one at Fry's in Seattle, and I can tell you those
things are JUNK! Typical low priced Chinese production with typical QC
issues and inconsistancies. It looked cheap. For me, one of the other
key factors is the deck as well. Flat decks were all the rage in the
70's, but skates have evolved since then. It is beyond me why eXkate
won't put a decent concave deck on their board.
The only "innovation" that eXkate has offered since before Electric
Louie sold the company a few years back is to offer custom airbrushed
decks. The eXkate is a great product, but you have to evolve your
products or you won't be successful. Where is the NiMH eXkate? I bet
that David at E-glide has a NiMH option within the year.
Can you imagine a powerboard with high enough power and low enough
weight to skate bowls and snakes? That would ROCK!

If anyone has video/images from any EV event that they would like to see
on the Internet please get in touch with me. I am especially interested
in any images of videos of John Wayland and his vehicles for possible
inclusion into his website.
Thanks

The pellet would be calcium carbide, but it is not a catalyst, it is used
up in the reaction.
I do not know about it being used to run the engine in model T's but in
early models it was used in the headlights.
http://www.modelt.org/rcarbide.html
I have heard of attempts at running engines on the stuff but do to high
combustion temperatures and very rapid combustion speeds the engines did
not last long.

If you wondered what happens when sealed batteries of this sort are involved
in an accident here is what happens. They mostly crushed with no puncture.
One battery ripped open from the pressure. There is a mat like material
that makes up the cell. No spillage. No corrosion. The battery while low
in voltage and sagging badly still charges and runs the car as do the other
deformed batteries. One battery with some plastic chipped off is at normal
voltage. I guess these batteries are absorbed glass mat. These were from
the Ranger EV. 8v Delphi/East Penn. I used these batteries in a 56
VW/Aspire and Lectra.
