--- Begin Message --- Quick question: I just traced down a ground fault in my E20 to the armature connections on the motor (3-4hp shunt wound). I feel smart, but this is a fault that can pass 30+ amps (lift motor).

Can this simply be accumulated dust from the brushes for the past 30 years? The brush cap is sealed (no vents to outside); maybe it's full o crud.

Does this make sense?

Hello John, 

The distance in free air is not the problem.  Its when these string of 
batteries end up with both ends of the strings are together that are touching 
each other. 

Do the following test using one battery:

Using a volt meter, measure the voltage of the battery. 

Now keeping one lead on a post, move the other lead off the other post and 
making contact on the plastic top next to this post.  Read the voltage. 

Slide the test lead across the top of the battery closer to the other post.  
Notice that there will be a voltage change from maximum to a minimum reading. 

If the battery is new and has never been charge or the battery cells never 
vent, you may not get a reading. 

Do this test on a older battery that has been charge and cycle many times, and 
you will get a voltage reading.  The voltage is tracking across the top of the 
battery. 

If you get a reading in the middle of the battery along its edge that is half 
the voltage of the battery, than its time to clean the batteries. 

No matter how much you clean it, you will still get a small indication.

Looping the string of 12 volt batteries with 6 batteries per roll, you will 
have 12 volts x 12 batteries = 144 volts between two adjacent batteries, NOT 
GOOD. 

Charging these batteries with the two end batteries in the string, will 
increase the tracking from and will arc over.  

Also, if your battery pack is in a uninsulated metal battery rack, the charging 
voltage of 150 volts or more will be from any one of the batteries to the frame 
of the battery rack.

The best layout for a string of batteries is to have all the batteries in one 
roll.  If that is not possible, than loop back with a air space between the 
rolls.

In my battery pack, the maximum voltage difference is 72 volts between only six 
batteries in the pack of 30.  I space these at about 1/4 inch inside a 
insulated battery box. 

I used to have a 90 cell battery that was in a epoxy coated aluminum box.  One 
time I was charging these cells I notice arcing of the many cells to the sides 
of the box when it was dark.  You cannot see this faint small arcing in the day 
light. 

So even with my T-145's, they are space, I do the dark test once in a while.


Battery Connection Test: 

In one of my E-mails, I stated do not work on the batteries while it is 
charging.  There will be the maximum charger voltage from any one of the 
battery post to the ground frame of the EV if it ground to the same ground of a 
on board charger. 

One exception to this, is to do a BATTERY CONNECTION TEST WHILE THE CHARGER IS 
ON. This is very dangerous and you must take extra ordinary cautions to do this 
test. You have to dress up the EV and your self in insulation rubber blankets 
and rubber gloves to do this test. I used to work high voltage live over 10,000 
volts. 

Drape a rubber mat over any metal part of the EV you may be contact in.  Place 
another rubber mat over the batteries, except the ones you are going to test. 

This test, is to check the continuity of the battery connections that go from 
one battery to the next.  You will perform a SHUNT TEST by placing the test 
leads of a multimeter in parallel with the connection from one battery to the 
next. 

Place the test leads on the lead post of the battery, not the cable terminal 
end.  Using the millivolt or even the milliamp scale, a good connection should 
read about 0.01 volts or less. 

If one of the battery connections read higher than the others, keep the test 
leads on that connection, tighten that connection until the voltage reading is 
the same as all the others battery connections.

I used a In.Lb torque wrench on my first installation and torque to the battery 
specifications. Then I do the shunt test to see what the voltage reading is.  I 
than used that as a reference for a quick check of all the connections using 
the shunt test.  

When installing a new set of batteries, record this reading so you can used it 
as a reference for your next test. 

After running a EV with new batteries for about 5 miles, it is recommended to 
perform this test to see how much the battery connection shrinks back.

  Subject: Battery Hookup Question (Am I missing something?)


  Hello folks,

  Sorry if this has been answered before.  The search feature in the archive 
  is tedius at best for finding answers.  Type in battery connnections and 
  just about every post comes up because the word bettery is used in just 
  about every post.  Anyways...  The question. Preceded by a statment or two.

  I plan on having two 144V strings of batteries.  Each will be two rows of 
  six positioned so the connections can run pos to neg down one side and up 
  the other with a disconncect at one end (to split the pack for servicing) 
  and the two cables coming out the other end to go to Zilla, via contactors. 
  With the batts positioned right, the two cables and their connecting bolts 
  will be two battery widths apart at the end closest to the controller.

  I have read somewhere that this is not a good idea because of the voltage 
  potential at the one end could cause some kind of arcing problem.  Yet, the 
  cable connects on my Zilla for the B+ and B- are about an inch apart.  If 
  there were to be a problem with arcing,  I would think it would happen 
  there.

  Am I missinterpreting the "potential" problem?  Are there other contributing 
  factors that I am missing?

  Thank You

  John J

Ryan -

You could make the problem a bit more tractable by simplifying it to one of these two questions:


1. What would the cost of gas have to be for this conversion to pay for itself in N years? ( And, you decide what you want N to be - 10 years, for example)

OR

2. If gas averages $5/gallon ( or, some other price - you pick it) for the next several years, how long will it take for this conversion to pay for itself?



The cost of electricity to recharge probably won't be a major factor. The big costs will be the initial converision and periodic battery replacement.

And, decide what at speed you really will be driving this distance every day. There's a big difference in power needed at 60 compared to 70 MPH.

Also, don't let anyone convince you that you can do things to get the Cd of your truck down to 0.25 in order to make this work.

That raises another question - do you really need a truck to carry you to work and back? If you're concerned about payback period, why not convert a small, light, aerodynamic car? ( but, it would have to be one that can carry a lot of lead)

There is some detail or too many unknown variables that stifle me when
I attempt to figure these out.


My current situation is a 2001 Ranger with a 4cyl/5spd.  Commute for
school is 50 miles round trip unfortunately.  Truck averages 20 mpg...

Fuel might be $5/gal or more(or no fuel at all..) with this Houston hurricane.

At what fuel price point do I actually save money by having this
vehicle be electric?  How long does it take to pay off the conversion
cost in fuel savings?  How much will it cost to recharge it 5+ days a
week?

Potential conversion items:

Zilla, PFC charger, a 9" motor(or some other size if that would be
better) from Jim Husted that costs less then an ADC, any batteries and
amount.  Could put them under the bed or in the bed or both.

25 miles there, and 25 back, can't charge there.  Nearly all highway.
60, 65, an 70 mph limits.

I will do it if the figures show a savings over time. Will this be cost worthy?

You might be able to improve motor efficiency by 1% or 2% with a well
designed automatic transmission, but I think you'll end up loosing that
much, or more, in the pumps and controlls.  If you come up with a really
good design, you /might/ improve total efficiency by 1%.  You have to
decide whether or not that is worth all the extra cost, complexity, and
time

If there is a CVT tranny available for this car that might be easier. Still less efficient than a manual but better than a traditional auto tranny. LR...

I looked at it as just the operational costs alone. 
If you try to roll in the cost of the conversion vs. a
gas car that is paid off, that isn't a fair
comparison.  Try this:
batteries: $1200, amortized over a 4 yr. lifespan =
$300/yr.
charging cost: $72/yr. ($6/mo. for me).
$372 per year.  I drive 3,000 mi. per year.  (Small
town, sorry)

3000 miles, at 30 mpg (Honda Civic = 100 gallons of
gas.  Gas is $3/gal. = $300.  Electric loses in my
case.  But the warm fuzzies I get from students and
fellow drivers, plus the guiltless driving for all of
those wonderful reasons makes me eat the $72 no sweat.

Here's another one: 
Gas cars depreciate 20% the moment we drive them off
the lot, and continuously as we rake up the miles and
gaskets go, carbon deposits build.  But EVs aren't
allowed to depreciate!  We want top dollar when we
sell them b/c the parts don't wear in the same manner
as ICE vehicles.  Seems to me that we have to factor
in depreciation as well despite less wear & tear.

Other unknown variables:
Need a stated value policy.  Mine is an extra $20/mo.
over regular policy (Allstate).  I ignore the
difference, but would be paid in droves in an accident
over ICE cost.

Increased brake wear?

Less time spent in repair shops.  What price do you pt
on that?

peace,

The situation with that is my Dad thinks about the air conditioner on
the side of our house and how it runs up the electricity bill in the
summer and the charger slugging away for 6 or 8 hours recharging a
144+ volt pack..

How can I convince him that it's different?

Current recharge prices:

The situation with that is:  I already have the truck.  Also, it snows
here sometimes and it's like bumper cars out there when it does. 
Also, it's handy having the truck bed to haul something big and bulky
every once and a while(lawn mower, furniture, helping someone move,
hauling brush, etc.)

I'm kinda partial to this truck right now.. :)  I might do a high
performance small car in the future after I do my other car..

Sure will David - If I get any circuit info I will pass it along - who knows
it might be the same. Certainly the layout is similar - back axle turned

interesting to see your controller board ( I have attached picture of

John,
I agree, it very well could be a similar or the same drive train, I just
don't have any experience with the Griffons. Sorry. I am hoping to find a
schematic, tech manual, something on the Chloride controllers in the
Conceptor G-vans. Or even better would be the guy or guys that might have
designed / worked on them and knows something about them. I really would
like to bump the voltage up to 240 but I want to do it safely. Got the
room
for the extra batts and I could sure use the extra range. Keep in touch
and
let me know how you get along. David Chapman.

Setup in the Saturn is as follows:
12 Trojan 30XHS flooded batteries
PFC30 charger.
 
Trojan says to charge to 14.6 volts per battery, so 12X14.6 is 175.2 volts. I 
have the timer set to 3 at the moment. It brought the pack up to 175.2 volts 
and the timer light started flashing. It was slowly dropping in current near 
the end, but shut off at about 8 amps still flowing in to the pack. I should 
have more time on the timer until it trickles down to about an amp right?
 
Thanks


Later,

It might not be fair.  But this is the situation.  This is a vehicle
that is paid for.  Could drive it for the next year as is or convert
it to electric if it would save me money and the conversion costs
would be paid off through the savings of not buying fuel.  There is no
getting around it.

Lifetime warranty on pads, rotors, etc at AutoZone.  Front pads are a
one time $19, rotors are $63 should I need them...

I do *all* my own work.  I hate taking vehicles in to get tires.  I
have before removed the wheels and just brought in the wheels/tires in
another vehicle and had them swap the tires.  That way they didn't
have to drive my car, mangle the underside on their lift, and over
torque my lug nuts with their impact gun set to 600ft/lbs...  I should
take a pic of one of my wheels of a bar code sticker sticking out from
between the edge of the wheel and the tire bead...

I'd order my tires online and mount and balance my own tires if the
two machines weren't $1,000 each... :(

Hello Ryan, 

There is so many variables between all type of EV's, the weight, distance, 
speed, depth of discharge, cost of batteries. 

So here's is the data on my EV for the last 10 years.

In 1995, the cost of gasoline was a average of $1.50 a gallon,  it is now $2.75 
a gallon.  The average cost for 10 years is $2.12 a gallon. 

In 1995, the cost of electricity is $0.05 cents a KW and today is $0.07 cents a 
KW.  The average cost for 10 years is $0.06 cents a KW. 

In 1995, my batteries which was Excides 6 volt 220 AH which cost $45.00 each.  
$1350.00 for 30 of them.

Distill water cost $0.50 a gallon a month.  or $60.00 for 10 years. 

I drive my EV 50 miles a week which discharges down to 60%.  Charge the 
batteries to 85% in 60 minutes that start out at 50 amps and taper downs to 0 
amps or for a average of 25 amps. 

Watt hours = 25 amps x 240 volts = 6000 watts or 6KW

6Kw x .06 = $0.36 to fill up to run 50 miles. 

If gasoline is 36 cents a gallon, than that would 50 mpg. 

The average gasoline cost for the last ten years is $2.12 a gallon, therefore: 

                 $2.12 / $0.36 = 5.88 

                   5.88 x 50 = 294.4 mpg equivalent

Now lets add the cost of the batteries: 

Batteries and distill water cost $1410.00 for ten years. 

$1410.00 / 520 weeks = $2.71 a week. 

$2.71 battery cost + $0.36 = $3.07 

$2.12 average gas cost /$3.07 = 0.69

0.69 x 50 miles = 34.5 mpg 


My new set of batteries which are T-145's cost $2400.00.

Distill water at $0.75 a gallon per month = $90.00 

Ten years = $2400.00+ $90.00 = $2490.00 for batteries.

Per 50 miles per week = $2490.00/520 = $4.78 

If electricity is $0.10 per KW by than, therefore: 

Average cost of electricity = ($0.06 + $0.10)/2 = $0.08 

Charging cost per 50 miles = $0.08 x 6kw = $0.48 

Total cost for 50 miles = $4.78 + $0.48= $5.26 

If gasoline is at a average of $5.26 per gallon in 10 years then that would be 
50 miles per gallon.

Another EV system, could be completely different. A EV that weighs 1/3 of my 
does, and does not have A/C, Power steering, Power brakes, three electric 
heating systems, 7kw inverter system, sound system and array of instrument 
systems, double insulation battery enclosures and water tight cast aluminum 
equipment enclosures which takes enough energy to run a EV on its own, would 
come out with different results.

Hi Jim and Jerry,

I, or rather NEDRA, got an interesting email from James Worden yesterday about the Sunrise body available on ebay. Apparently James is a big NEDRA fan. James Worden was running Solectria in its hay day and is now CEO of Solectria Renewables. He made several range breaking records with the Sunrise. Alot of us were hoping the car would make it into production.

Anyway, here is what he says about the body:

"Just to let asociation members know, there is a lightweight, all Composite Sunrise Electric Vehicle Body for sale on Ebay.  This is the body that was used for the 380 mile record range run and the Boston - NYC highway speed run without charging.  It would make a really exciting build project for a group of EV'ers, an EV club or just an experienced car builder.  It would make an awesome base for a drag car because of its very low weight and great aerodynamics"

So as James mentions, this is the "actual body from the car" not the mold. But you could get the body and make a mold from it I suppose. Jerry would know more about that though.

Um, so is the object on eBay an actual body that could be used to build into a complete car, or is it "just" the mold? Or one builds it into a complete car and then takes apart again to use as a mold?

Every time I figure it out, a used 3 cylinder Geo Metro for $3000 at 50mpg
does a whole lot better than the EV.  4 Seater, zippy, no problems with
range.  I have an EV because I am tired of breathing all that crap that
comes out the tail pipe, and more than happy to pay for the clean air.  I am
also happy not to be at the mercy of bush and the oil controllers.

Money is only one aspect of EVs.  Quality of life is another.

It could be caused by carbon dust and oils.  You would need to remove the 
armature and clean it.  It could be degraded insulation that may need a rewind 
but it might also be something your local shop could dip and turn.  More info

Can this simply be accumulated dust from the brushes for the past 30

Does this make sense?

Very Cool... The L/D is a little low.  Going from 48 to 30 would take
some getting use to, but saving $30.00 a tow to 2000 feet would add up.

Noel there is another one (also in Germany) that is built just 
to get off the ground and avoid the tow. I think he only has 
10-15 mins of duration but its a lot less battery etc to haul 
around when your up and they are discharged.

Hi
 I am considering batteries for my electric dirt bike. System voltage 24 or
36 V. I am looking for something around 20 Ah capacity. I was thinking of
B&B EVP20 or some such. Does anyone have experience with these? Are there
any other batteries that I should be considering? Also can someone recommend
a good charger?
 Any tips or advice will be greatly appreciated. Thanks.
 BR Deshpande.

A non EV'r(my Dad for example) would look at that and say "well look

alternative which is fuel cost:

2001 Ford Ranger 4cyl/5spd, 20 mpg:

Costs me $30 a week to fill it up at $2.xx/gal

52 weeks in a year = $1,560

Hmmm....

Electric wins?  It looks like it too me.

Rough numbers...

50 miles at 20 MPG needs about 2000# of batteries (2.5 gallons of gas times
800# of batteries to store equivalent energy of 1 gallon of gasoline.)

If the commute takes less than one hour, then AGMs are preferred. If the
commute is more than one hour, flooded are preferred. I don't know your
commute so I can't judge this.

2000 # of 6 volt Concorde AGMs would require 30 batteries at $200 each for a
total of $6000.
http://www.backwoodssolar.com/Catalogpages2/battery2.htm#CONCORDE

2000 # of 6 volt T105 flooded would require 30 batteries at $88 each for a
total of $2640.
http://www.backwoodssolar.com/Catalogpages2/battery2.htm#TROJAN%20T-105%20BATTERIES

You can probably beat these prices.

The AGMs will take you further at high speeds and the flooded will take you
further at lower speeds. There is some debate about the time where this
crossover occurs.

The big question in my mind is the cost and amortization period on the
batteries.

If you get 400 W*h/mi. then the 50 mile commute will take 20 watt hours. If
the charging process is 80% efficient, you will need 25 kWh out of the wall.
At $0.10 this will cost you $2.50 daily.

I did not find the discharge data on these batteries, therefore I do not
know if 30 batteries will store 20 kWh. You will need to verify this for
your choice of battery.

If fuel goes to $5 a gallon, the fuel will cost $12.50 daily. The electric
will save you $10 a day on fuel.

If you spend $2k on a controller, $2k on a charger, $2k on a motor and $3k
on batteries and $1k on instrumentation (and wiring), and throw in the labor
for free, the conversion will cost $10k.

Spending $10k to save $10 a day on fuel will pay off the conversion in 1000
days (about 3 years.) This coincides with the time you will need to replace
the batteries. Your mileage will vary.

The good news is that the second battery pack costs only $3k and saving $10
a day on fuel will pay the batteries off in less than a year. If the
batteries last three years, the second two years are free.

In my example, the payoff period is four years.
