It is best to have a larger fuses before your switches, like a main circuit
breaker or fuse disconnect before your branch circuit breakers or fuses.
After the branch switches and/or contactors there should be branch type fuses
for every device. Lets say a device is rated for 20 amps, than a 20 amp
circuit breaker or fuse would be the rating for this circuit.
If the device is a motor or any machine that surges when it starts up, than you
fuse it for 125 percent over the running label rating on the equipment or 1.25
times the running amps.
If you have a motor that runs at 10 amps than you fuse it for 10 A x 1.25 or
12.5 amps with a Fustron or a Limitron fuse that is design for these surges.
Many running devices have a service factor on the label or in the
specifications where you can add another 1.15 or more to your fuse rating.
Normally you can use the next rating fusetron rating of 15 amps.
If you used standard fuses, you may have the double the ampere rating to about
30 amps. This higher rating will not protect the device on overloads, but will
protect the circuit on violently shorts that could cause fires.
Size all you wire ampere rating 125 percent rating of your device. Example:
No 12 wire rated at 20 amps for 16 amp device
No 10 wire rated at 30 amps for 24 amp device
No 8 wire rated at 40 amps for 32 amp device
No 6 wire rated at 50 amps for 42 amp device
No 1 wire rated at 125 amps for 100 amp load.
All of these would be fuse or circuit breaker for the rating of the wire as 20,
30, 40 and etc. A device that has a 10 amp rating that is tap off any of these
wire ratings, would be fuse at the device for 12.5 to 15 amps. This protects
the branch circuits and equipment, not the feeder circuits.

I've got two contactors, one on either side of the motor/controller.
Still, I suppose I could see high charging voltages with my wiring
setup; my Todd DC/DC will probably complain and die. I'll have to check
through posts to see if there are any better converters.
When you said I needed a fuse 'before' each contactor, were you thinking
of the 12V side, the 144V side, or both? And is there any real meaning
to 'before' in the electrical sense, or should I just wire a fuse nearby?

driven off the pilot shaft of the motor. This unit is a large Delco unit that

output is 7000 watts at 120 VAC.

no longer gains speed in a down hill run of which I had to keep braking which
has become dangerous on snow and icy roads.

In Orlando, I pretty much have to run the A/C all the time. Especially
in the summer. I've heard too many stories about over-revving the ADCs,
so I don't want to sit at the light in neutral, gunning the engine.
That's annoying, anyway. I decided to go with a separate accessory
motor instead.

It all just a matter of knowing your limitations: Victor's client base appears
to have more money than time, so they will have a working EV quicker by simply
paying for the development time invested by others (i.e. "time is money") - I'd
love to be able to afford a drop-in system, right down to the differential!

Ignore all your fuses already in your car. Way too big for any safety
there. Just get your two wires connected to the pack at an accessable
place. It might be nice to have a 100 amp Anderson as the connector point
just incase you have a friend with a big charger. Lawrence

I'm in the process of hooking up my e-meter. I have the prescaler
hooked up, and meaured the output voltage - before hooking it up to the
e-meter. My 144V pack is resting around 157V. The 0-500V prescaler was
showing 54V on the output. I was expecting around 15V.
That's an easy one. The prescaler forms one half of a potential divider,
with the input impeadance of the e-meter itself forming the other half.
Therefore the output voltage of the prescaler would be full pack voltage if
it weren't for the fact that a zenner diode has been incorporated to limit
the output to a safe level.

Sometime ago I posted a story that my EV, a converted Daihatsu Charade,
had some melted batteries after I lent it to a friend. It was not his
fault, it was the charger!
It is a Zivan NG3 and it would seem that it is an intermittent problem.
The charger just continues to deliver max current and does not go to the
constant voltage phase.
Anyone had problems with NG3s?

I am wanting to measure Peukert numbers, and I am looking around the shop
for some simple, easy to build 100A load for a 12V battery. I am sure I can
coil some wire and stick it into a garbage pail of water, but I am not sure
how long of wire, and more importantly what gauge of wire.

You need a fuse between the rectifier and the battery to protect against a
shorted rectifier burning up the wiring to the pack. It should go close to
the battery.

I think you are being a bit generous calling this
company (Geo EV) a car maker :)
I don't claim to know all the safety issues associated
with LiPoly, but I can tell you that I work every day
with an EV (one that IS built by an actual auto
manufacturer), that contains LiPoly batteries. While
we have had some ups and downs with the BMS, we have
had no problem at all with the batteries (and yes we
occasionally charge them indoors).
This, obviously tells you nothing about their safety,
but it does tell you the risk averse auto makers
generally don't produce things (even in low quantity)
that are a massive safety risk.

Use coat hanger wire. A full length of the small diameter wire pulls 150
amps from a 12 volt battery. The larger gauge is about 250 amps. Use two or
more in series or parallel to get the current you want. They need to be
submerged to not burn out. They last several weeks until they rust through.

I sold an IQ 450 Vego to a Firefighter with a bum leg. He uses it to get
around different parts of the city on inspection. It is that wild green
color. It's in San Francisco. If anyone is looking to buy a charger for a
Vego and/or you see it's a punk with a green Vego it's a good chance it's
him. This was stolen the Haight Ashbury, San Francisco neighborhood. It
was in perfect condition. Spring seat, totally stock. Missing the top
compression collar just below the handlebars. . GRRRRRRRRRRRRR....

I took the IQ450 to work the Haight Street Fair today, locked it up at McDs
next to all the kids bikes. Then... some Punk Stole it! Took Balls to do it
in broad daylight in front of all those people. He must've waited for the
parking lot guy in to go inside too. Man I was pissed... I should've taken
it inside. Oh well, it was a nice ride... I got to use it 3 times! $40
bucks a ride! I even bought two chargers for it. Good thing I didn't bring
my Ebike and gotten it stolen... I'd still be hunting the guy right now.
Let me know if you see it or hear about some kid looking for a charger.

Yes. I have a prescaler that I cut open and traced out the circuit.
There's a PC board with room for a lot of parts, but most of them are
not installed. Functionally, the 100v prescaler is just a 118K 1%
resistor from +PACK to +VSENSE (pin 5) of the E-meter. The 500v
prescaler is a 1057k 1% resistor from +PACK to +VSENSE (pin 5) on the
E-meter.
They also have a 51v zener diode and 0.01uF capacitor from +VSENSE to
-VSENSE. The zener prevents the voltage from being too high if the
prescaler is not connected to the E-meter. The capacitor helpf filter
noise.

I'm about to purchase 6 new 6v bats for my Elec-Trak I-5. The bats that
are currently in it (3 years old) will go in my E-12m. That will leave
me with a very tired (about 9 years old) pack of 6 bats lying around and
6 equally tired bats in my golf cart.
I don't have a lot of test equipment, so I'd like to ask how I can
easily figure out the 6 best bats out of the 12 so I can avoid buying a
pack for the golf cart until next year.
I have a 12/6v 6/2amp battery charger, so I guess the first thing to do
is get all the batteries out and individually charge them, but I'm not
sure what to do next.
Thanks.

The first way that comes to mine is to charge them in parallel then hook
them in series and put a load on the whole pack , then check the voltage as
they discharge , as soon as one hits 5.5v pull it out and number it . repeat
till done. there is a few problems with this though, you may have a few that
just need wakening up , since they come form somewhere else. They might be
good and need cycling. another way would be to drive the cart , find the
worst battery after a good drive , and replace it with one of your others,
( after charging , and charge the one that your putting in also ) . a 6
amp charger is not very big for a golf cart battery. could take 2 days
charge. ( unless it is putting 6 amps out all the time , a mine pfc :-)

Thanks. I'll try this. I know the batteries don't need "waking up"
'cause they are all used EVery week. In the case of the golf cart, it
is used pretty much every day or so.

Hey everyone. Power of DC update will be up soon. Lots to talk about.
Apologies for messing up the Digests.
Before I send out Power of DC info. I want to test this out to see if
my messages are continuing to truncate the digests. If so please let me
know. Also if not please let me know.
I went back and tried to turn off any html mail Format settings. Didn't
see anything. Noticed a Format setting was at "Rich Text" and changed
that setting to "Plain Text". Not sure if that will do anything or not.
This is a mail program that came with my OS 10.2.6. The mail program I
had been using, Entourage (the Mac version of Outlook), blew up on me
three weeks ago. It has some memory problem which I can't figure out.
It wouldn't let me delete old messages and in the "In Box" titles of
messages don't appear in the window unless you click where they should
be. Also if you scroll the window the messages titles don't show up
(just a blank white space) or some do and others don't. I tried
deleting the preference files and reinstalling the program and that
didn't work. So I just trashed Entourage and am using this one that
originally came with the Mac, which I don't particularly like and now
its truncating the Digests. Arghh
If this continues to mess up the EVDL I can go downstairs and use my PC
to send mail, which has Outlook running and my mail already set up. Its
just more convenient to do everything on one computer instead of
switching back and forth since I do most my work on the Mac which has a
huge studio screen.
If I can figure out how to get Entourage working again that would be
great. Entourage didn't mess up the Digest like this mail program is
doing.

Have I missed some posts somewhere?. I don't see any post Power of DC posts.
Anyway,
I had great fun.
I need to express my deepest gratitude to Mike Goliwas, Dave Cover, and James
Sullivan for all of the sweat, hardwork,
sweat, effort and sweat that they put into helping get my Jr. Dragster almost
built. Yep you read it right, almost!
Man we were close, too bad the track wouldn't stay open 'til sundown.
I think I let them down big-time. If I had been a little(lot) more organized or
gotten off to a much earlier start, I
think we would've had a much better chance. Previously I had written something
about Barring any Wayland type
events.....
Wednesday, I was giving the car a final once over with the tech portion of the
rule-book. Mind you, this car was built
in '95, the rules have changed a little. I needed to change some of the
steering, which I did. Then I noticed, had to
change the brake lines, why didn't I notice this before. Well here's a problem,
wrong parts, small town, no parts.
Spent most ofthe day Thursday looking for some adaptors for the braking system,
no luck, not locally anyway. I planned
on leaving by noon on Friday, so overnighting parts was not looking good, Chip
offered to let me overnite the parts to
his house and he would bring them to the track. But Chip was already burdened
with coordinating the event so I didn't
want to load him with that if I could avoid it. At damn near the last minute I
was given a contact in Syracuse that
may have the proper parts. So I called them up. They are a hydraulic hose
house, and knew exactly what I needed, but
didn't have enough in stock. But, they did have enough of a similar item, that
they, and they're professionals you
know, assured me would be suitable. I ordered it and told them I would pick it
up on my way through.
So, Friday morning comes... I go gather some last minute parts, nuts, bolts etc
that I have written on my checklist of
things to bring. (really, I had a checklist) Then off to U-Haul to get my
rolling garage. After spending way too much
time at U-Haul re-wiring my trailer light connectors, I was finally on my way
home, to load up.
I had my wife checking off the checklist as things went into the trailer, but
like all checklists, there is always
something missing.....
About halfway to Maryland I realized that I had forgotten to bring my welding
helmet. After waking up late, I followed
Bob Rice to the track to drop off the truck and van and then head to
Wal-Mart/Home Depot to get a welding helmet and
some brake fluid. We arrived at the track and pulled into EV central at around
9 something. The BYU team was already
there and in the middle of their Discovery Channel interview with their
capacitor powered EV-1. As an interesting
aside note... On my way down I was running some ideas through my head as to how
I could add a two speed transmission
capability to the Jr. I envisioned a plan that I thought would work out well
and shelved it into the back of my mind
as a possible future upgrade. Then lo and behold, I look under the hood of
BYU-s EV-1 and there sits the 2 speed
transmission that I just envisioned on my drive down, weird!! I'll let them
descibe it, if they wish, but basically
it's two chain drives with selectable clutches.
So, I'm waiting for Bob, so we can go shopping for the stupid parts that I
forgot, when the Discovery Channel starts
shooting his Rabbit. I end up catching Mike G. and we head to the big box
stores. WE finally get back to the track at
about 10:30 and now the gates are open, so we have to wait in line to get in.
At 11:00 we finally start working on the
car, we should've started at 8 and I should've done more at home first.
The good news though....
We did get the bettery pack wired and got power to the controller, so Mike
could hook up his controller programmer and
set me up with 4 different selectable modes of operation. SO, I have all week
to finish the car and get Cody to my
local track this weeekend to run the car. I also was told when I finally got
home yesterday, that my local track
officials will allow Cody to compete head to head with the ICE Jr. Dragsters,
which is *not* allowed by the official
NHRA rules.
Now the sad news...
I spent all day working on the car, never got to talk in depth with any of the
other participants, nor watch any of
the runs. I'm pretty sure the other guys didn't get to experience much either.
Sorry guys, really!! They drove a LONG
WAY to this event and spent all of it helping me, rather than experiencing the
rest.
On a lighter note....
Cody and I were originally going to pass on the after event, event. But we went
anyway, I'm glad we did.
I'm looking forward to running this car in Florida in January, and
.......that's your cue Shawn......

Hi EVerybody;
Hmmm, not much posted yet for Power of DC, so I'll brake the ICE and dive in!
My adventure started in CT about midnite Thurs. Nite. Had the 82 Rabbit " Led
Sled" hitched up to my trusty, faithfull Ford E150 van, ready to roll south.
Plan was to get through the NYC traffic harah BEFORE daylite. Passed through
that area over the George Washington Bridge, Gees! For what they get for tolls
they COULD fix a few of the deeper potholes?The ones you look in the mirror to
see if you LOST any expensive stuff on.Got over to central NJ and called what
was left a night. Pulled into a rest area, Feh! Not very restful! With the
price of Diseasel fuel whythehell don't trux SHUT DOWN when they " rest"???I
was so pooped that I slept through it, though.
Daylight, and it gets too hot to sleep in a vehicle, so on the road again,
arriving at Hagerstown about noon. Felt I should award the old Ford with an oil
change at a Jiffy Lube place. Ya know one that you pull through? No problem, to
tow the EV through, too. Needless to say it DOID evole a few questions. Funny
EVERYbody in H' town knows where the Mason Dixon Dragway is. Just ask, the
friendly locals will direct you. "You're gunna run THAT?' Cool" I said that I
wasn't gunna really tear up the track with speed , but EV's were coming from
further than CT to run tiomorrow AM Come on out! Maybe they did?
Gassed up @ 45 BUX worth, and that's at the cheaper prices in MD, like $2
03 I think it was? I hear you folks in Europe enveying that! Headed out to the
track. Nobody around yet. Unhooked the Rabbit, parked the Van under a shady
tree and headed into town, happy hum of a traction motor. Rabbit was fairly
juicy, from CT home charging, as it had ben plugged in before I left home.
Cruised down the Duel Hyway, the Main Drag there. Called around, Chip, Hey Chip
I didn't hang up on ya. The Cell Fone ran out of juice! Had to go buy another
car charger that worked! Now I could check in with other folks, Most were still
coming. Checked into the Motel 8 for the nite, went in and showered and
crashed, it is a damn LONG trip to MD from CT, especially at 55-60 MPH, as I
didn't want to push it hard, a tired old 78 Ford, ran about 25-28 hundred RPM,
loafing along. EVERYTHING in the world passed me!" Targeted Inforcement Area"
signs made me laugh in PA. HAH! Go get "em Boys! I thought. !
Right<g>! You NEVER see a truck pulled over, now do you?They are the worst
offenders speedwise, you are correcting as they buffet you in the wind blast as
they rocket by! It's a leasurly White Knuckle flight being SLOW on the American
Race, I mean HIGH way. Ya would think at the price of Diseasel Fuel, that they
would ease up a bit??
Meanwile, back at the motel, around dinner time started to stur, Hmmm? Where
IS EVerybody. Cruised over to the suggested Texas Steak House or whatEVer, the
suggested feeding place. Forgetabout it! EVERbody in MD was there, so went over
to the Bob Evens just in time to miss Keven Zak and the guyz there. Stuffed my
face and went back to the Motel after cruising down through the old section of
H'town, parts that have been there more than twenty minutes!In A EV you DO get
a few looks and stares.Found the grand old Train Station, a throwback tio the
RR era. No trains grace H town, nowadaze.
Tim Humphry had pulled in with a U Haul trailer, was right above MY room, I
had asked for a down stairs room, with charging in mind. Tim had parked right
along the building as he HAD to with the long rig. So I pulled alonside there
NEXT to my room, sprung the screen away enough to slip my cord out, and plugged
'er in. cranked the variac up to 10 amps and let it charge. Had I the right
adapter I coulda plugged it in to 240, from the AC plug, but I wasn't gunna do
without the AC ,that muggy nite! Motels are getting harder to plugfitin, as
thet are sealed Big block type buildings hard to park close to your room and
feed a cord out. During Tour De Sol I plugged into the ubquitus Coke machines
on the walkways. but THEY are inside, nowadaze. Sigh! But where there is a
will, can be a way. I cruised through several Motels looking for handy outdoor
outlets. A new thing, judging motels by Outlets, rather than other
amenities<g>! SOMEday they will say" 120-240 volt Outlets at the EV!
charging area. Resettable breakers, for our valued guests"
After a decent nites sleep ready to face Race Day. We all went out to the
track, rounded our vehicles up at the EV "Ranch" to asemble, both people and
vehicles. Tim started the daunting task of converting a Junior Dragster to
electric, he had EVerything he needed in the trailer, except TIME! He almost
made it but 5 pm came and went and it wasn't ready to run. Had we raced SUN he
woulda been ready!
OK the burning question answered. The Rabbit? Yeah I ran it. Just drove over
to the staging area and when the guy waved me on, pulled up to the Right lane.
" Roll yur windows up" he said. Of course I tried to do a smoke show, Wayland
style ,back where everybody else in gassers smoke the tires BEFORE the race.
Yank up the hand brake and dump the clutch in first. it DID break loose! Did
anybody shoot my first run when I DID spin the wheels, all the nice water on
the track sure helped! Maybe a little Diseasel Fuel, next year<g>? Rolled up to
the lights, and was off to a BLISTERING 17sec.52mph run! The second run was
about the same, and the third, and forth. Maybe I should Bracket race?On run my
other runner was Orange Juice, He ran away from me so fast! Hell! I have run
TRAINS that were/are faster! Acela woulda passed me down the track! All 700
TONs of him! I coulda taken him off the line, though! The Metro North and MAX
guys woulda run away from me, too.I have never had the!
Rabbit on the track before, my .62 reaction time wasnt anything to crow
about, better than 1,78 though<G>!Those ae good enough in RR service though.
Nothing broke, though by now after over 5 years woulda broken before.
Between runs it was the Gofur car, go get gas for the genny, a COLD drink or
more, or what it was built for, the clutch slips like hell when you push/ race
it like that. Had I planned ahead, I woulda put a stouter clutch in before
going racing. It was a classis " Run what ya Brung" thing. Was it worth it? You
Bet! To see you guyz in person, meet more Listers face to face, THAT'S where
it's at! EVerybody THANKS for Being There, coming from Utah" Greatest Snow on
Earth" tags EVen, Hot as hell, but it IS summer in the Global Warming era,
whaddoya expect?Folks came from further away than I did.
All in all, it was a pretty good turnout, considering that the East had been
a dead zone for EVers for years. Oh we have a way to go to catch up to the Left
Coast, but we arent competing here, just to get EV's and EVers to link up.
Maybe something midway? Between east and west?Hard to do as it's a vast country
and gas isn't getting any cheaper!
I'll seeya at Woodburn, but not bringing the Rabbit, just the Prius, faster
than the towing rig! John Wayland has his stuff together, by then, it'll be a
hellova racing season!
Seeya
Bob OK guyz the REST of the Power of DC stories!

If you stip 100 times like that during a day,
it is 50A*10sec*100 = 50,000As or 13Ah. You better notice
that amount put back in the batteries.

If you put 50 Amps in for 10 seconds I assure you that you could not

Didn't see anything. Noticed a Format setting was at "Rich Text" and

It will indeed. It's the equivalent of the HTML settings of other
programs. "Rich Text" means that the text allows complex formatting.
This is a mail program that came with my OS 10.2.6. The mail program
I had been using, Entourage (the Mac version of Outlook), blew up on
me three weeks ago. It has some memory problem which I can't figure
out. It wouldn't let me delete old messages and in the "In Box"
titles of messages don't appear in the window unless you click where
they should be. Also if you scroll the window the messages titles
don't show up (just a blank white space) or some do and others
don't. I tried deleting the preference files and reinstalling the
program and that didn't work. So I just trashed Entourage and am
using this one that originally came with the Mac, which I don't
particularly like and now its truncating the Digests. Arghh
Mail is an alright program, but it does have it's limitations. I've
never used Entourage so I can't comment there. I've used Eudora on
Macs for years and love it. There is a free version you can download
and try. Might work better for you than Mail.

Do the math. V=L dI/dt

200A (HV system) would be plenty for me. Byt I got your point Bill.

My EV ('92 Celica) has a 9" ADC motor, stock 5 spd/clutch/flywheel, and is
driven with 14x8V flooded cells through a Raptor 600 controller. Compared to
the ICE motor, the DC does pull better at low RPM, and (as you imagined) does
seem to "go away" at higher RPM's. With only 112V nominal to work with, I can
only draw about 150 Amps near redline (about 5000RPM and 45 mph if I remember
correctly). So if I stomp on it in second gear, it pulls hard (at about 400
battery amps), and then eases off as the speed goes above about 30 mph
(estimating about 3500 RPM). It continues to pull, but takes forever to get to
40 mph. If I shift "early" (at about 30 mph) my current will stay high, and my
speed will increase faster.
Everything I've read tells me to keep the RPM's high, which helps cooling, and
range, but if I'm pulling out into traffic, I have to shift at lower RPM's.
If I drive at a steady 40 mph, I can drive in 2nd or 3rd gear. The difference
in current drain (for constant speed) is hardly noticeable between the gears,
and often I go ahead and upshift, anticipating the need to go faster. (and at
lower RPM, I'll have more acceleration at the ready if I need it).
My range is about 35 miles, which is all I need, but if I had to do it over, I
would probably go with a higher voltage pack (to give me more torque at the
higher RPM's).
Regards, Jim Seibert

I have yet to experience an EV for myself. With a DC motor and
transmission, what's it like going through the gears compared to an
ICE motor? Does it pull initially then go away? Does the motor only
rev to a certain point then appear to "stall out"?

I think we're all a little late on updates, but the 5th annual Power of
DC event-- put on by the Electric Vehicle Association of Washington,
DC, in conjunction with the National Electric Drag Racing Association--
was among the best I've ever seen. This was my first "East Coast" event
and it was very well done.
I'll let the NEDRA folks report performance details. Orange Juice had a
very interesting configuration, and the BYU guys took things to a whole
new technology level with their ultracapacitor-powered EV1. There's a
lot more to say, BUT.... here are some pics and you'll find more info
embedded beneath many of the images...
http://www.megawattmotorworks.com/photos.asp?album=pdc2005
For those of you with a thirst for EV video, you'll find a 5Mb MPG
video of Orange Juice on page two of the album.
Enjoy,
