Hello John,
There may be a Discharge Floor (or minimum limit that you fuel gage or
E-meter may be set at).
If the E-meter has a Discharge Floor of 100% meaning it displays the full
100% range of the AH of the battery as for example for a 100 AH battery:
Battery charge to 100% is 100% display or 0 AH used on the meter.
Battery discharge to 50% is 50% display or 50 AH used or remaining on the
meter.
If the Discharge Floor is set to 50% and the battery is at 100% charge, it
will also read 100% on the E-meter but when the battery is discharge to 50%,
this will read 0% on the meter.
I have the same type of batteries you have, T-145's which are 260 AH. If I
set the AH and the Discharge Floor on a Link-10 E-meter to 100% and
discharge to 80% remaining, the E-meter shows about 52 AH use or 260 AH x
20% = 52 AH
If I set the E-meter to a Discharge Floor to 50%, then the E-meter displays
26 AH use at 80% or
260 x 50%= 130 AH, then:
130 AH x 20% = 26 AH use which is display as 80% on the E-meter.
The 26 AH is actually 90% of the capacity of the battery but it displays as
80% on the battery.
I rather leave the Discharge Floor at 100% and never discharge below 50%
which would be about 130 AH left in the battery or if one battery reads
about 6.01 volts at no load what ever comes first.

Hi Roland,
Its not an e-meter type device, just a cheap battery fuel gauge. It has a
couple of adjustment pots, but they are only 270 deg units and not well
calibrated. It is designed for a forklift to shut off a lift motor when the
battery reaches a minimum volts per cell. I think it is set for 1.75 VPC
from the factory or what is supposed to be 80% discharge. I did not connect
the interlock as I am only using the unit as an indicator and I don't have a
lift to shut off.
I think the meter is basically showing a minimum voltage so that if the VPC
drops to say 2.05 it moves to the left to that point and doesn't move back
up until it is reset by a charge or power cycle. Then on the next
acceleration if the voltage goes down to say 1.98 then the meter moves a
little farther to the left. I think there is some damping in the
electronics as I don't see the needle move on accel. It just seems that it
is dropping faster than the standing voltages that I am reading.
I think my question is about the "don't measure the voltage right after a
discharge", is that admonishment because the voltage reading would be
incorrect to the low side? I thought I understood that the voltage will
rise to some extent after a discharge is stopped.
I may just need to tube the "fuel gauge" and get a straight DC voltmeter and
learn the voltage limits. I am not yet ready to go for the Link 10 or
E-meter route as I hope to get to that level with the Tropica chassis for my
next conversion/restoration.
respectfully,
John Neiswanger

Subject: Battery standing voltage question
Hi All,
I have been taking short runs with the electric bike and have come to a
question about the standing voltage readings I am getting.
Specs. Trojan T145 floodies
running a 48 volt system, and charging in parallel 24 volt string.
I have a Curtis "battery fuel gauge" which I think is actually just a
minimum recording volt meter.
After a 5 to 10 mile ride, the "fuel gauge" reads anywhere from 1/3 to
3/4
full. But when I read the voltage with a DMM I read 80 to 95% charged
based
on a chart that I downloaded from Trojan's website.
I understand that the instructions are to not measure the voltage just
after
a charge or a discharge. I expected that to be because just after a
charge
the voltage would be overly high and that just after the discharge that
it
would be falsely low.
My current draw is 80-125 amps as I cruise and can surge to 300+ on
acceleration. I expect that I am getting bit by Puekerts effect on the
fuel
gauge. My basic question is does a heavy discharge cause an overly high
standing voltage reading? I have taken the readings anywhere from 15
minutes to the following day with similar results.

Forklift. Or NEV / GolfCart.
You could run a motor-cycle with such a controller,
but for a car it is usually too little power,
unless you are OK with a car that can't go on the Freeway
or one that is extremely small and light and aerodynamic
and has a 0-60 expressed in minutes ;-}
That is why Electro Automotive recommends to have 96V or more
and the 600A of the haviest Curtis 1231 seems to be regarded
as pretty light by most converters.

To pump 34KWH into a pack in 1 hour you would need a 34KW charger and at say
192V it would push ~180A. To do it in 10 minutes you
need a 204KW charger and at say 192V it would push over 1000A. Thats not a
small charger :-(
but it would be impressive, and almost as much so to charge in 10 minutes.

I was just perusing the NEDRA sight and realized a current trend. A
few vehicles are switching voltages up and down and gobbling up alot of
the records. I understand in a free world to the victor goes the
spoils but it makes me kinda sad. I always enjoyed checking out the
record list of names from all different places, times, and
configurations. Maybe it's just that I noticed my mother's 96 volt SC
record got wiped recently. Are there any NEDRA limitations to how many
voltage classes can be held by one vehicle? I have no doubt for
instance that Dennis could take the CE dragster from top to bottom any
day of the week he chooses, (Oops I forgot he's not a member), but you
get my point. I have time slips to show the Orange Juice running WAY
faster than some of the lower voltage records but since I had my sights
on Ken and Jim's 240 volt number I never turned them in. Does anyone
else feel this way or am I just too sentimental?
Shawn Lawless
PS: I guess it's out with the Zapi and lead, in with contactors and
V28's, and down to Battery Beach with the Electropolitan to grab back
that 96 volt record. Wanna go to Florida mom?

device produces a magnetic field that magically produces small amounts of
electricity when moved around.
mmm, don't you get a bit of electricity when you move one magnetic field
through another?
isn't the earth surrounded by a huge magnetic field?
wouldn't there be drag when moving the one field through the other?
there's no free energy, to get it, you have to move the magnetic field,
which will consume more energy than is created
reminds me of the people that suggest putting windmills on electric cars so
you can produce the electricity to run the car 0-o

*********START OF MEETING ANNOUNCEMENT***********
Topic: EVs for Dummies: The Electrathon
Date: Saturday, Nov, 18, 2006
Time: 10 am to 12 noon.
Site: Alameda First Baptist Church
1515 Santa Clara Ave, Alameda
Visitors welcome, open to the public.
This will be our last Chapter meeting of 2006. Besides
holding our usual election / selection of Chapter
leadership for 2007, we also have a special
presentation by Chapter member Bob Cooley on new
efforts in the East Bay to introduce Electrathons.
Bob has been instrumental in getting a couple of local
High Schools started with this great hands-on
educational and sports activity. Electrathons have
been around for many years. It is a type electric
marathon race of High School age students, in which
the winner is determined by how far you go in a
certain time with a given amount of battery power. In
addition to creating races and competitions between
schools, each school creates a class for students to
be involved with the building, testing and refinement
of these vehicles.
Come see what an Electrathon is all about and how we
can support efforts to educating our students through
this medium.. Also other EVs will be on-hand and
informal Q&A can take place in the parking lot.
See you there.

about 400 miles the first month - all in town. Part of that increase could

be the "noise" of month to month changes - an extra day or two in the meter

Hello John,
Reading the voltage at load and/or right at the load will not correspond to
the Trojan battery open voltage and specific gravity chart, which I also use
too.
Deep cycle batteries as being discharge, depleted the current first from the
surface of the batteries grids, then more current comes to the surface deep
from in the grids.
This is call the defusion of the acid deep inside the plates to the
electrolyte, which takes some time to do if the battery plates are very
thick, is where the deep in cycle came from.
A battery with very thin plates, but more of, will discharge all of the
surface charge charge all at once, so the defusion time if less and this
type of battery normally has less ampere-hour but a high cranking ampere for
a shorter period of time then of a deep cycle battery with thick plates.
It is normal for a battery that has a charge percentage of 80%, which is
call State of Charge or SOC, which will read about 6.25 volts at no load,
but may sag down to 6.01 volts which is 50% SOC, but the specific gravity
will be about 1.238 sg which correspond to 6.25 at 80% SOC.
For long life, it is recommended to not discharge below 50% or to 6.01 at no
load. You can do discharge down to 20% one time for a test. I did this one
time after driving 40 miles on some grades that were 5 miles long and my EV
started to slow down showing a sag voltage of about 5 volts.
So I turn around and drove down hill for about 5 miles. This let the
battery to do some defusing time and I make it all the way back home which I
then had a open voltage of about 5.8 volts or was about 20% SOC after 15
minutes of setting time.

One way to reduce your electrical bill, is not to charge the batteries above
90% or even 80% every time you charge it, unless you have to squeeze every
bit of energy out of your batteries for your range.
If you have to deplete the batteries below 50% on every drive, than its best
to have a higher AH battery for range and long life.
My battery cycles for a 260 AH battery is from 90 to 80% which takes out
about 25 AH which takes only 30 to 35 minutes to charge to 90%.
About every three and sometimes every 6 months, I water, do a balance charge
and then charge the batteries to 100%.
Trying to break my old record of 12 years on my last set of batteries, which
were Exide X something of 235 AH.

HI-
First check the tach sensor by remeving the phone jack marked tack.
Sometimes the lead or the sensor it's self will be defective. This desables
the
rev. limiter, so don't continue to run with it disconected after testing.
Check the air gap between the sensor and the black white marks on the shaft
or pickup wheel, also be sure there is no intermittent light striking the
sensor
such as sun light or light reflecting off a moving part.
Next make sure the throttle sensor wire is not routed to close to the
hi-voltage
leads or the motor, it may need shielding.
Hope this helps.

Yeah, I thought they have all those voltage classes so everyone with an
electric car can be a World Record Holder. It isn't fair if someone is
hogged them all.
How many cars compete in each class?

Are there any NEDRA limitations to how many voltage classes can be held

records but since I had my sights on Ken and Jim's 240 volt number I
never turned them in. Does anyone else feel this way or am I just too
sentimental?

PS: I guess it's out with the Zapi and lead, in with contactors and

that 96 volt record. Wanna go to Florida mom?

Except their challenge is part of the scam. Makes them look legitimate so
they can sucker in more investors while they spend YEARS decided which
scientists get to test it.
Check out: http://en.wikipedia.org/wiki/Steorn
Everything they say about this project is vague, we were developing a
micro generator for /unamed company/ in partnership with /unamed dutch
company/, all of our results have been verified by /unamed individuals/
working for our company and our /unamed/ parner companies.
They haven't been filing their legally required paperwork for yers now so
you can't check that to find out what they are doing or who they are
working with.
The last time they filed they were over $300,000 in the hole with a cash
reserve of about $150. FOr this project they claim they have raised some
$5 million.
I'll give them credit, it's difficult to debunk their device since they
have revealed practically nothing about it besides aknowleging that it
defies the laws of physics.

Hey guys, I'm trying to evaluate fets vs IGBTs for my motorcycle

I think this (to be honest) motorcycle is a perfect bed for an ev drive
train of your choice. At 120vdc it'd be a real great performer. As they
have it now they have an K91 size motor that is fan cooled. With just an
L91 and higher voltage this would be a very good hill climber. It is pokey
slow now but with battey weight down low it has good potential. If anyone
else has seen it and has ideas please feel free to comment. As is it's an
ok city car but I think it should be geared down to 30mph. Then it might
climb hills better. A sepex system would work well in it. I suspect you
could get gliders from China for much less than the 8k Zap would want for
them. Lawrence Rhodes.......

According to norwegian newspaper today, new documents
tells that Ford Motor Company sold Think Nordic to the
indian businessman Kamal Siddiqi's company Kamkorp in
January 2003 for one USD.
Ford bought Think Nordic in 1999 for 25 million USD,
and invested over 150 million USD in to the new
electric vehicle consept was almost finished.
Ford also put over 20 million USD into the company to
ensure that Kamkorp sould at least run it for 18
months. These numbers has been known from the
bankrupcy investigation
"We paid this to ensure that the production of
electric vehicles in Aurskog, Norway should continue"
says Ford's vice-executive in Europe, mr. Ingvar M.
Sviggum.
He will not comment that there was other willing to
pay a lot more for the company.
The old founders of Th!nk is now back again after Mr.
Kamal Siddiqi's bankrupcy with the company Th!nk
Technology. Their aim is to produce 5000 cars in 2008.

Well since my name is in this post I will reply.Shawn is correct in posting
the CE dragster could take all the voltage class records(if I were to become a
nedra member again)But you will not see me doing this,I do not think it fair
to upcoming competitors.
I am also
building a S10 pu to race in the SC class between 240 to 348 volts.I plan on
using this pu as a daily ev driver.To race in the SC class however one canot
have
a rear end other than the stock housing.I did not read all the rules however
before I built the S10,so I did put in a 9in.ford already.So I assume (if I
join nedra again in the future)that I will be in the pro street class.After
reading about the current SC class record holders its come to my attention that
they may indeed also have 9in ford rears.So my question to nedra can the rules
be
bent?And how much? Dennis Berube

Hear hear HEAR!
I do support your idea.
In fact that is one of the reasons why NEDRA made sure you can only register
for one voltage class a day.
Well that was the point...
And They should stick with it.
