I have some general questions as I'm still a newbie:
1. What do you all typically use to insulate your tools for working around
high voltage? I came within a millimeter of blowing myself across the
parking lot and smoking my controller. I suppose I could wrap with
electrical tape but is there anything better?
2. Flooded NiCads were recommended to me by a list member. I have some
questions but I don't think he's in town or my email isn't making it past
his spam filter. So....
a) What are NiCad's flooded with? I don't imagine you add water as with
PbA batteries.
b) What is the expected life span of a NiCad pack?
c) Will my old Lestermatic PbA battery charger work with NiCads? (220v 40
amp charger)
d) My (imperfect) understanding is that the NiCads will deliver the rated
current right up until they are completely discharged unlike PbA's which
drop in output even before the rated time (Puerket's Effect?) Am I
understanding this correctly?
e) What effect does cold weather have on NiCad's vs. PbA batteries? Does
the range still decrease? How much?
Thanks in advance,
Rich A.

Granted, but the normal outlet would be the cheapest way to do it hands down. I
think a new Avcon unit is over $1,000, but if the EAA has a stash of them you
could possibly do it cheaper.
In my experience too, and I'm running a conversion here, is the Avcon's
eventually require service. Here in Arizona we have some charging
infrastructure left from the late 90's and they put Avcon's in because the
power companies had Rangers. I don't know if it's from lack of use or what, but
there are a couple of them I can't get to work no matter what, and the power
company shows little to no interest in fixing them even though they are still
there. The outlet wouldn't have these issues.
Just trying to keep things simple.

So, isn't it true that the Avcon heads have GFCI, auto resetting over current
protection, and pull away protection?
Seems like you want one of these if you can get it, right?

If you need a simple outlet, you could just use an Avcon converter box.

I have one of the old NJ transit forces. They have only Avcon input. :(

Is there an availability problem with the SPI chargers at Fry's today? Will
there be if one is removed?

We can't tell now. At the time you did it, you could have removed the
16-amp load and watched what happened to the voltage. If you hadn't
reversed a cell, then the voltage would very quickly go back up to
almost 11.x volts. If you *did* reverse a cell, then it would only come
up to 8-10 volts. If you reversed *two* cells, it would be ~2v lower
yet, etc.
But on a new Hawker, the cells are probably matched well enough that
they all went dead at about the same time. So, the odds are that you
shortened its life, but didn't kill it on the spot.

In the April 2 show, "This New Car" explores: Does Everyone Need To
Own A Car? In the U.S., patronage of mass transit grew steadily from
1900 (six billion passengers per year) to 1927 (over 17 billion), but
plummeted during the Great Depression. Patronage grew again during
War II, peaking in 1946 at 23 billion riders, but then dropped
steadily every year until the mild renaissance of public transit in
the early 1970s. However, the total number of riders in 1970 was
still less than that of 1910. The reasons for these declines are
complex and often political. Los Angeles, for example, had over 1,000
miles of trolley and interurban lines before 1930 - but this system
was taken over by a private company, dismantled, and replaced with
noisy, polluting, and comparatively slow buses. Since few people
chose to ride them, costs rose, thereby cutting the number of
passengers further. To reduce costs, private companies eliminated
outlying branches and smaller stations. These trends, along with
inexpensive gasoline, suburban and highway development, the
deterioration of older subway lines, and the greater freedom cars
offered, have helped turn the U.S. into a car culture. However, as
the public has grown increasingly concerned over the impact of cars on
the environment and the quality of life in urban areas, there is
growing support for the development of more efficient and comfortable
mass-transit systems.

Yea, I think the EAA has a few at least.
<..snip..>
While I concede that an Avcon head may require more maintenance then a simple
outlet, I'm afraid that the first person who connects a charger with the power
turned up too high will put us out of business until we can get somebody to
flip a breaker.
> The outlet wouldn't have these issues.
I worry tripped breakers, and cars with ground faults shocking patrons.
It seems like a single "I got shocked" report could end our charging at
Fry's days...
That and a simple outlet would make it less convenient for me. :)

The cell ran at about 2V but when I attempted introducing a low voltage
source, a variable 0-14V 20A power supply the cell volts "broke free" and
went to O/C volts again requiring an increase of volts from the other source
in series with the light bulb to re-establish the cell. Ill try longer times
at low current and perhaps my old trick to remove shorts in NiCd cells- a
blast from a 10000uF cap charged to 50V.

What did happen when you applied a higher voltage for several days?
5 years dead is a *long* time! You may have the face the possibility
that they are not just slightly dead, but permanently dead.

Damon, you disappoint me :-( You need to get up to speed, dude! The

just the way I predicted they would 5 years ago. They close the valves

with the electric motor. Having all the valves closed amounts to the
same thing as having them all open, in that there is very little drag
against the electric motor, probably not any more drag than the Prius'
drag caused by the planetary arrangement they use.

Hi all,
I've been playing with Uve's EV calculator for a while now (thanks for
making it if you're reading Uve!) and I've found I have the range I need
for commuting, but am trying to make a decision between 6V and 8V
batteries and felt the need for an acceleration calculator. Borrowing
the motor constants from Uve's page, I think I have a reasonably
complete model, complete enough to at least give realistic relative
performance between different battery, motor and controller choices. I
do have a couple of gaps that I'm hoping some of the more experienced
can help fill in. Any estimates, wildass guesses or sources would be
fantastic!
Overall resistance of battery wiring, contactors, fuses. (I think I
recently saw 50-100 mOhms in a post)
Motor and controller efficiency at different operating points - I think
I've heard that WZ's motor would be running at 50-60% efficiency. Is
this because of massive current? I think I remember hearing that motors
and controllers are less efficient at lower speeds and a lower duty
cycle. Again I'm just looking for numbers to help make it more accurate
so anything would be great.
I'm doing this in Excel so hopefully a lot of people will be able to
open it and I'll be happy to pass it around as soon as I'm done. Thanks!
Erik

First let's define "shorted controller" as one where pack voltage is
applied to one phase.
Under those conditions, the induction motor most certainly will lock
up. OK, to split hairs, not quite. It might turn maybe a revolution
per second but through the gears, that's as good as a lockup.
if you don't believe me, try it. Pick up any AC motor you have
sitting around. Put as little as 12 volts on any winding. Now try to
turn it. You can but just barely. Now imagine the full operating
voltage as DC on that winding.

Does anyone have one of these who can actually meter it and see what
it is? We have 3 versions on record now.
a) Lee awhile back said that it is an LM-10 temperature transmitter.
b) This stock number looks like a diode part number. Reasonable, as a
forward biased diode is a very good temperature sensor.
c) I started using 10kohm thermistors before I was told anything
different. From 0-25 deg C, the E-meter display agrees with the
temperature on the sensor within a degree or two.
I suspect that b) is probably correct and c) is close enough for the
current the E-meter subjects the sensor to. I'm certainly going to
try a diode as soon as I can AND measure the current to the sensor.
If you have one of these sensors and a DVM, check it on either low
ohms or "diode check". If it conducts one direction (perhaps reading
about "0.6xx on the display) and infinite the other then it's probably
a diode. If it reads the same resistance (about 10kohms) both
directions then it is a thermistor. If it reads more resistance one
way than the other then it might be an LM-10.

Well, just got done watching it, and it was awsome! Poor Rich got picked on by
Jesse a lot though. Getting all the work done that they did in a week is
deffinitely impressive, of course a lot of it got done magically like the dual
coupled motors just appearing.
My single favorite part was when Shaun Lawless was tightening a cable to a
buss bar on their battery racks with the batteries in the box. He shorted two
with a wrench creating a nice big spark at which point he just goes back to
tightening it some more, creates an even larger spark, throws the wrench on the
floor and yells that he needs a new wrench!
There was also a lot of technical stuff that was left on the cutting room
floor. You don't get to see really any of the wireing of the car happen, you
barely see Rich put the controllers in the car. I suppose this stuff isn't a
big deal to the average viewer.
Rich and Shaun, I give you guys (and the others on the show of course) credit
for getting that build done on time. Plus it was pretty cool they had the Tzero
on there for a few minutes and let Rich drive it.
I still gotta go check my other computer, which has my tv tuner card, but I
should have it recorded.
Later,
Ricky

Good quality 3M electrical tape. Others probably have better ideas. You

The electrolyte is a solution of Potassium Hydoxide. When it's low, you add
distilled water, just as with a lead battery. You should maintain
completely separate watering tools for lead and nicad, as any acid
contamination will ruin the nicads.
> b) What is the expected life span of a NiCad pack?
It depends on how it's used, but typically 2-4 times the life of an
equivalent lead battery. Some nicads have served for 10 - 15 years, even
more.

It would require modification. The charge control algorithm is wrong for
nicads.

Nicads' voltage doesn't fall off very much until they are almost completely
discharged. Then it plummets. This is both good and bad. ;-)
Peukert's effect refers to how current drawn affects the apparent capacity
of lead batteries. It says nothing about their voltage on discharge. It
also doesn't apply to nicads.
> e) What effect does cold weather have on NiCad's vs. PbA batteries? Does the
> range still decrease? How much?
Nicads have appreciably less capacity diminution with cold weather.
However, most nicads are more sensitive to damage when operated in very hot
climates, as are NiMH. This makes them most suited to use in cooler
climates.
Hope this helps.

I understand that some may not want to join the Yahoo group. But believe me
there is a LOT of serious study going on and the members of Prius Technical
Stuff are very knowledgable.
If you're keen to hack a Prius, PTS is a much better source of info than
this list, which after all is aimed mostly at true EVs, not at the Prius.
I'm a member of PTS, and I find it very interesting. Highly recommended.

That was very cool. As a bonus a favorite local Mopar Master Ron
Jenkins brought a Hemi for some TSB's. Not to mention Tom Gage and the
Tzero were showcased. Those guys rock.
We got to get Shaun some EV wrenching lessons ;)
Rich, you were tolerant of all the crap for sure.

My family has owned a 1997 Mazda MPV for many years, but we blew the engine
about a year ago and it has been sitting in our driveway ever since. We
decided to look into converting it into an alternative energy vehicle rather
than just buying a new engine or scrapping it. Our kids are homeschooled
and we thought that it would be very educational all around, we would get to
keep our beloved mini-van, save the planet from a little pollution and
potentially wrestle ourselves from the soaring cost of petro-fuels. As we
are newbies to this subject, we are sort of in the dark.
We were (are) very interested in BioDiesel, but from the data that we've
found, it seems that it is not possible to convert a gasoline powered car by
simply installing a diesel engine - so apparently that is not an option with
the MPV. Ethanol seems like a good option since the conversion looks fairly
straightforward and cheap, but is really predicated on having a reliable,
working engine. Since the MPV is old and heavy I am a little concerned
about investing so much money to get it running well again. EV seems like a
_great_ option in terms of being maintenable, but I am concerned that it is
too heavy. Given the size of the vehicle, however, I am wondering how much
of the weight is currently in hardware that we would be removing anyway.
Can anyone give us some advice.
Thanks!

I have to agree with Ricky's assessment of this episode of Monster Garage. I
recorded it from DirecTV and have edited out the commercials. It has been
burned to DVD and saved to my pc hard drive.

Well, just got done watching it, and it was awsome! Poor Rich got picked on
by Jesse a lot though. Getting all the work done that they did in a week is
deffinitely impressive, of course a lot of it got done magically like the dual
coupled motors just appearing.
My single favorite part was when Shaun Lawless was tightening a cable to a
buss bar on their battery racks with the batteries in the box. He shorted two
with a wrench creating a nice big spark at which point he just goes back to
tightening it some more, creates an even larger spark, throws the wrench on the
floor and yells that he needs a new wrench!
There was also a lot of technical stuff that was left on the cutting room
floor. You don't get to see really any of the wireing of the car happen, you
barely see Rich put the controllers in the car. I suppose this stuff isn't a
big deal to the average viewer.
Rich and Shaun, I give you guys (and the others on the show of course)
credit for getting that build done on time. Plus it was pretty cool they had
the Tzero on there for a few minutes and let Rich drive it.
I still gotta go check my other computer, which has my tv tuner card, but I
should have it recorded.
Later,
Ricky

Hello to Damon and All,

You don't have to follow the Honda Hybrid list, all you have to do is
stay current with regular car magazines. Pretty much all of them have
featured the latest improvements and changes of the new hybrids. The big
news is that Honda's latest version of the Civic Hybrid can run a few
miles on electric power only, just like the Prius does. Compared to
Toyota's complex trio of an electric motor-generator, a generator, and
an ICE all coupled together via sun-planetary gears, Honda gets it done
in a far simpler, more elegant way with their IMA system (integrated
motor assist) with just the one motor-generator (less than 3 inches
thick) sandwiched between the tranny and the flywheel and sharing the
ICE crankshaft...no extra gears, no convoluted electrical-mechanical
swapping of power and loads.
>...but in my defense the particular engine being sold appears to be
from an 05 Civic :-)
That's why I qualified that my comments were for the new 2006 model.
See Ya...John Wayland

Could I talk you out of a copy of that file? http://www.yousendit.com
works very well for anything under a gig.

Blew that one, didn't I? LM-35.
I've been sitting here doing some calculating while looking at the
LM-35 app note (lee, is it Fig 5 or Fig 8?) and I can see why a 10k
thermistor would work well in the ambient temperatures we have around
here.
I use those cheapo indoor/outdoor electronic thermometers on my
refrigeration in the restaurant. With semi-trained gorillas as
employees, they live hard lives and get replaced often. Thus, I have
a large collection of temperature sensors, AKA thermistors. The
thermometer usually has a 15 ft or more lead on the thermistor which
is perfect for use in a car. On my MH, I encapsulated the sensor in
some 6mm glass tubing, bored a hole through one cap and inserted it
into the electrolyte. It agrees within a degree of a
silicone-encapsulated thermocouple stuck into the same electrolyte.

I have some general questions as I'm still a newbie:
1. What do you all typically use to insulate your tools for working
around high voltage? I came within a millimeter of blowing myself
across the parking lot and smoking my controller. I suppose I could
wrap with electrical tape but is there anything better?
I wear thin blue rubber gloves while working on the pack.
These prevent about 99% of the shocks you would get otherwise.
Taped tools work surprisingly well.

2. Flooded NiCads were recommended to me by a list member. I have
some questions but I don't think he's in town or my email isn't
making it past his spam filter. So....
a) What are NiCad's flooded with? I don't imagine you add water
as with PbA batteries.
b) What is the expected life span of a NiCad pack?
c) Will my old Lestermatic PbA battery charger work with NiCads?
(220v 40 amp charger)
d) My (imperfect) understanding is that the NiCads will deliver
the rated current right up until they are completely discharged
unlike PbA's which drop in output even before the rated time
(Puerket's Effect?) Am I understanding this correctly?
e) What effect does cold weather have on NiCad's vs. PbA
batteries? Does the range still decrease? How much?
Thanks in advance,
Rich A.
