I have a P&B KUEP-11D15-12 which is a DPDT contactor rated at 150VDC
and 3A per contact. I want to use this to switch my single ceramic
heater module... I'm running 192V pack voltage.
The ceramic heating element is not a resistor; its current changes
depending on airflow and temperature (higher airflow and lower ambient
temperatures raise the current). Your pack could be just off charge, and
so at 240vdc. A runaway heater can be a very bad thing! So, I'd provide
a considerable safety factor "just in case".
I think the KUEP is too small for this applicaion. I'd use the next
larger one, the PRD series. For example, the PRD-7DH-12 has two 20a
125vdc contacts, which can be used in series for a 20a 250vdc rating.
The 2-pole version is not normally stocked, so you may have trouble
finding one.
Also, you want to include an RC "snubber" across the contacts. For
example, a 10 ohm resistor and 1uF 400v capacitor in series, across each
contact. This will considerable reduce the arcing when the contacts open.

Are these connectors suitable for disconnects? They would not be used as
emergency disconnects just disconnects when there is no power going anywhere,
motor contactors are off. They would be used just as disconnects so that the HV
components can be worked on.
Or would the slight arcing that does occur tend to weld them?

With all due respect to Rabbits, and those that
convert them thanks to good kits from reputable
converters, it's less likely you'll come close to
breaking even with a model like that, _in my humble
opinion_.
That's funny. We have several times come into possession of Rabbits
converted with our kits, or assisted the owners with sales, and they
have always sold in the range of $6,000 - $7,500. This is close to
the cost of the parts, and the original owners got several years of
use out of them first.

Any shunt of 0 to 50mv that is rated for the main line ampere you want to
use. The shunt sense screws are all ready calibrated for that size shunt.
I am using a shunt that is rated for 500-1000 amp for my 800 amp meter that
I used for the motor amp. I cross check it with my Zilla Amp on Tack which
I program into the Zilla. This switches the speed sensor circuit that goes
to the tack to the a internal motor amp senser in the Zilla.
The amp meter and Amp on Tack reads the same.
I got my shunt from EV Parts.

I do not see a positive locking type grip in these type of connectors. It
is best to use Anderson Connectors, which the end of the connectors
interlock to each other.

These push and twist to lock. No spring or real retention design so may
not be suitable for shock/vibration environment unless maybe there was
an additional strain relief with anti-twist.

PG&E Asks For Electric Car SupportSept. 4 - BCN - Pacific Gas and
Electric Co. is asking its 5.1 million customers to sign an
online petition asking automakers to make plug-in hybrid electric
vehicles available for mass sale.
The vehicles, dubbed PHEVs or plug-ins, are currently part of
PG&E's company fleet. The electric vehicles can be charged
overnight by being plugged into a 120-volt standard socket and
can operate without any gasoline.
The technology for these cars is here today, but automakers
aren't convinced there are enough buyers for them, said Bob
Howard, PG&E vice president of gas transmission and
distribution.
That's why customers are being asked to go online to
www.pluginpartners.org to log their interest in the cars. A
notice included in September's bill directs customers to the
site, Howard said.
"The petition basically says, 'If you build it, we will buy it,'"
he said.
According to a study commissioned by the California Electric
Transportation Coalition, if automakers began making plug-ins
within the next few years, 2.5 million of the cars could be on
the road by the year 2020.
That's the equivalent of taking as many as 5 million of today's
vehicles off the road, according to the report. The addition of
the cars would also save 1.14 billion gallons of gasoline each
year, the report found.

Ener1 Installs First Phase Production Line
Tuesday September 12, 7:55 am ET
EnerDel Increases Manufacturing Capabilities With an Eye Toward
Becoming One of the Largest Li-Ion Battery Producers in North
America for HEV/EV Applications
FORT LAUDERDALE, Fla., Sept. 12 /PRNewswire-FirstCall/ -- Ener1,
Inc., announced today that its EnerDel battery company has
installed its first mass production line for lithium ion (Li-Ion)
battery electrodes at the company's Indiana facility. The
production line is capable of producing the electrode equivalent
of 5,000 Hybrid Electric Vehicle (HEV) batteries (25KW) per
month. The investment in this new equipment is an important step
forward in the Company's plan to become a leading, U.S.-based
supplier of Li-Ion batteries for automotive applications. EnerDel
can now demonstrate its production approach and expertise to
automotive companies and OEMs, as well as begin their required
qualification process to mass produce batteries for their future
HEV models.
EnerDel's production line also supports the company's work with
the United States Advanced Battery Consortium (USABC), a part of
the U.S. Council for Automotive Research a group for
collaborative research among DaimlerChrysler Corp., Ford Motor
Co. and General Motors Corp. The USABC is focused on securing a
supply of U.S.-based Li-Ion batteries for the U.S. auto industry.
In June, USABC awarded EnerDel a contract to produce a new Li-Ion
battery based on advanced battery materials and low-cost
production technologies. The funding validates EnerDel's path to
produce a battery that is lighter, smaller and higher in power
than existing HEV batteries.
EnerDel's production line includes two Hirano Tecseed Coaters,
along with the required facility infrastructure. Ulrik Grape,
President of EnerDel stated, "We've invested in the best
production equipment for launching the manufacturing program.
>From a quality control standpoint, it is vital to have two
coating lines to allow us to handle the coating of anodes and
cathodes separately to avoid any contamination."
He added, "Our Engineering team, one of our strongest assets, is
making the necessary modifications to the equipment in order to
achieve stable and low cost production based on their vast
experience scaling up Li-Ion battery production technology in
Japan and Korea where 99% of all Li-Ion battery production is
located."
EnerDel believes that securing a local, U.S.-based supply of
Li-Ion batteries for hybrid vehicles is crucial to the success of
automotive manufacturers producing hybrids in North America. The
U.S. is the largest market for HEVs and the majority of the cars
sold in the U.S. are also manufactured here.
Charles Gassenheimer, Chairman of Ener1, Inc. commented, "The
goal here is to reduce the dependence on foreign oil. It doesn't
make sense to switch our reliance on foreign oil to a dependence
on a foreign supply of Li-Ion Batteries for cars and trucks."
He added, "Our strategy is to become one of the first companies
to ensure a domestic supply of Li-Ion batteries. I am pleased
with the progress we are making in our ability to address this
challenge for the U.S. automotive industry."
About Ener1, Inc.
Ener1, Inc. is an alternative energy technology company. The
company's interests include: 80.5% of EnerDel
(http://www.enerdel.com), a lithium battery company in which
Delphi Corp. owns 19.5%; 49% of Enerstruct, a Japanese lithium
battery technology company in which Ener1's strategic investor
ITOCHU owns 51%; wholly owned subsidiary EnerFuel, a fuel cell
products and testing services company (http://www.enerfuel.com),
and wholly owned subsidiary NanoEner, which develops
nanotechnology-based materials and manufacturing processes for
batteries and other applications (http://www.nanoener.com). For

REVENGE OF THE ELECTRIC CAR 13.9.2006 13:22:30
In the mid-1990s, the future of transport looked like it might be
powered by electricity, with several large US manufacturers
producing electric cars which they leased to celebrities to
evangelise the technology.
Just three years later, production of the cars was stopped, they
were recalled en-masse, and sent to the shredder.
For this week's Dateline, David Brill investigates why the
electric car was not only abandoned, but why there was an attempt
to completely erase it from history.
And he discovers an electric car-buff underground keeping the
technology alive.
He is speaking here with Adam Connors.

This pge.com PR can also be seen at
http://www.pge.com/news/news_releases/q3_2006/060901.html
I signed the petition on
http://www.pluginpartners.org/whatYouCanDo/onlinePetition.cfm
A search on the pge.com site gives
http://www.pge.com/about_us/environment/electric_vehicles/
with some EV charging information.
I am a little surprised at this pge.com PR about promoting EV use.
Yes EVs are the Utility's friend, but in the past (circa 1990's)
PG&E has not been too warm about promoting their use or even making
PR like this.
Having said that, I also must state that PG&E was first in the area
to install EV charging before the conductive AVCON or inductive EV
charging standard were established. Some of PG&E s earlier EV
charging used twist-lock outlets before they started listening to
the EV community that twist-lock outlets are not a good idea
(vehicle moves for whatever reason and then there are live wires
dangling for the public to touch).
Some of those early EV charger attempts can still be seen at the
Walnut Creek, CA and Colma BART stations (round kiosk or blue boxes
on the walls). When I was at the SCAQMD CARB workshop
[ http://brucedp00.150m.com/carb0005/ ] their parking lot still had
some of PG&E /CALSTART's earlier designs
[ http://brucedp00.150m.com/carb0005/carb0005-102.jpg ].
I hope PG&E is serious this time, and will fully embrace the
production of publically-available highway-capable EVs.

Thanks Lee and Don,
It seems the DPST (PRD-7D-12) version is rare as it is with the KUEP. But I
think I got a bead on the DPDT (PRD-11D-12).
The funny thing is that with the KUEP the Contact ratings change between the
DPST and DPDT configurations. But if I read the spec cheet correctly for the
PRD series it seems the same 20A @125V rating for both configurations. So I
will look for either. I have some relays such as this in the shack but I'm
almost positive they do not have magnetic blowouts.
I already had the snubbers built.
The last question I have now is location of overtemp sensor. Do you put a snap
switch right on the element? or do you locate it of to one side in the plenum
to sense air temp exceeding what, around 200*F?
Mike,
Anchorage, Ak.

Page 7 of that patent looks alot like the capacitive EQ system. The
company has many thousands of patents.

This is good, and the price isn't too outrageous.
It doesn't seem that EV Parts sells cable anymore (didn't see it on
their site), but KTA lists 2.0 Prestoflex for $3/ft (but the pricelist
seems to be a year out of date).
EV Source has some very nice 2/0 cable in red or black with individually
tinned strands. It is a bit more pricey ($4.53/ft), but is probably
worth the premium.
One thing to watch for is the cost of shipping a decent length of 2/0.
KTA lists their 2/0 at 1#/ft. You may be best off to check welding
supply places local to you, or better still, wire/cable suppliers local
to you. The wire/cable places will probably have the best price, but
buying local and saving the shipping costs ought to be cheaper than
buying online from someplace across the country. For a local source of
tinned cable such as EV Source supplies, you'd have to check marine
supply stores.
Cheers,
Roger.

The easiest and cheapest way to get a DC amp meter is to use
a low-scale voltmeter (50 or 100 mV) and wire it to a shunt
resistor to convert the current flow to a (small) voltage.
This introduces a very small loss of energy, but nothing to
worry about, it also gives a galvanic connection to the
circuit that you are measuring, which is sometimes a problem
(you have the battery "High Voltage" wired into your dashboard,
so take care of double isolating that wiring and fusing it.
Therefore a clamp-on ampmeter can be preferred, the only
issue with measuring DC amps is that they don't register
that well and the clamp is very prone to offset errors
from magnetic fields.
That might be the reason you only see AC amp meters, they
filter the DC offset.
Shunt resistors usually sell for around $10 in the 1000A
range and panel voltmeters are available everywhere.
Make sure you use an automotive one, as the instrument
meters will rattle out of their needle bearing in a car.
Virtually the only concern (after the safety) would be
to get a good looking face plate for the meter.

My experience with PG&E in respect to EVs is very positive.
When I faxed my request to change my electricity meter and
rate to E9 (Time Of Use for EV charging) this was not only a
free meter swap, but it was done before I knew it (2 days later)
while I was expecting to get a phone call for an appointment
for the next month or so.
The other experience is nothing that I have personally
witnessed, but my US Electricar truck used to belong to PG&E
who assigned WaveDriver Ltd the task to remove the original
Dolphin controller and install a bi-directional Wavedriver
controller and 3-phase charge connector that could not only
receive, but also deliver 208V 60Hz AC power.
This conversion was done in 1995 after which PG&E tested
Vehicle-to-Grid backup capability of Electric Vehicles, in
case their presence would become ubiquitous they would have
a lot of decentralized backup power generators for the
infamous afternoon peak period.
When the Electric Car got "killed" in the political process
they must have lost their interest in this becoming a
solution for their issues with weak power grids, but that
does not mean they are not supporters of EVs.
Their actions speak volumes.

This pge.com PR can also be seen at
http://www.pge.com/news/news_releases/q3_2006/060901.html
I signed the petition on
http://www.pluginpartners.org/whatYouCanDo/onlinePetition.cfm
A search on the pge.com site gives
http://www.pge.com/about_us/environment/electric_vehicles/
with some EV charging information.
I am a little surprised at this pge.com PR about promoting EV use.
Yes EVs are the Utility's friend, but in the past (circa 1990's)
PG&E has not been too warm about promoting their use or even making
PR like this.
Having said that, I also must state that PG&E was first in the area
to install EV charging before the conductive AVCON or inductive EV
charging standard were established. Some of PG&E 's earlier EV
charging used twist-lock outlets before they started listening to
the EV community that twist-lock outlets are not a good idea
(vehicle moves for whatever reason and then there are live wires
dangling for the public to touch).
Some of those early EV charger attempts can still be seen at the
Walnut Creek, CA and Colma BART stations (round kiosk or blue boxes
on the walls). When I was at the SCAQMD CARB workshop
[ http://brucedp00.150m.com/carb0005/ ] their parking lot still had
some of PG&E /CALSTART's earlier designs
[ http://brucedp00.150m.com/carb0005/carb0005-102.jpg ].
I hope PG&E is serious this time, and will fully embrace the
production of publically-available highway-capable EVs.

This has been asked before but I'm still debating
which version has better potential in the EV use.
I'm talking about EVision - the product alternative
for e-meter. Displays any 3 (out of about dozen) parameters
simultaneously, one - on 25 LEDs bar graph.
A picture of its production display module is here:
http://www.metricmind.com/misc/dscn4980.jpg
There are no buttons on the display - they are remote (and optional).
On this particular proto wrong LEDs were used (hi intensity
white and blue, very directional) instead of rectangular light
blocks, so the illumination of units is not as uniform as it meant
to be, but it's easy to fix.
Point is, LEDs are brighter than LCD (at least those I could put
my hands on).
But of course 7 segments are quite limited in what can be
displayed. If non-numeric info is needed, it's quite cryptic.
Graphics LCD of course can mimic 7-segments and do much more,
but common ones are harder to read. Not so bad if they are
in a shadow deeper in the enclosure, and I lean toward this option.
I made couple of short videos (bad quality, by point-and-shoot
small digital camera) showing small "demo" running on
both displays. LCD is about 1.5"x1.5", and it is installable
right in place (instead of) 6 blocks of 7-seg displays, takes
the same real state.
LED version demo: http://www.metricmind.com/misc/dscn4874.mov 7MB file
LCD short demo http://www.metricmind.com/misc/dscn4870.mov - 4.5MB file
Any comments which flavor would you rather choose?
Also, would you rather prefer have no enclosure and mount it
behind the dash as any other gauge, or have it stand-alone
as on the photo above?
Thanks in advance for any feed back,

Here's the story. Morgan(speaks with broken Chinese accent) wants to do
business in the USA importing the vehicles on the above site. He also said
he has no idea how to do the documentation to even bring in samples for test
drives. I know these vehicles would be interesting to the Arcaners. Very
interesting to many of the EV groups. I think there are brain resources on
many of these lists that can help Morgan help us. He has the mainland
contacts. I know some of the Arcaners have done miracles getting cars
across borders. I also think making the cars a sort of kit would be a first
step in getting them into this country. I know California is very lenient
regarding EV's. Go to the link above and give Morgan a call if you have
ideas regarding getting some samples into this country for test drives. I
told Morgan no one will buy a vehicle without testing it. I've heard that
there are many ev's in Bejing now that the govt. there wants clean air for
the Olys. In China these are working vehicles. Why not here? Lawrence

BTW, let me take the opportunity to plug their WR2341 cable clamp (on
the same page); these are a very nice looking way to keep your 2/0
cables bundled in close pairs for low EMI (I use a handful in my EV).
Cheers,

Looking at the battery weight compared to the curb weight I'd assume the

What about dot-matrix LED displays?

Hi Jim etc,
I didn't notice any improvement in WH per mile or current draw though.
I then put in 30% copper-graphite brushes to reduce brush heating since I'm
running near the limits in a direct drive vehicle.

Hey Mark Great news! Was there any difference in current draw once you
advanced it? Also I'm wondering if in fact this is with the same brushes
(grade) as before? Anyway congrats, now you have that "I fixed it myself EV
grin" 8^) Cya Jim Husted Hi-Torque Electric "Mark E. Hanson"

(easier) 90 degrees, say it's 4" from mark to mark. Cut in half to 2" and
that's 45 degrees, then 1" is 22.5 degrees, half is 11.25, I then redrilled a
scooch over at 7-8 degrees into the motor rotation in the forward direction.
This removed my arcing and helped me sustain speed better going up hills on
my direct drive 72V Cushman and has done well for the last 1000 miles or 3
weeks of driving. best Regards, Mark
