It varies what the "trouble" is. With flooded NiCads 100% (and way more)
discharge is a way of equalizing them -- shorting each cell out to zero
volts with a bolted jumper, then recharge the pack again from zero. It's
only a problem for them if you have some of the string dead, and others not,
because you get reversed cells, I think.

Some time ago, before I did the last EV mod which included a Zilla, PFC and
180 volts of T-145's, I contacted ESMA in Russia at http://www.esma-cap.com
and a article at http://www.evworld.com/article.cfm?storyid=338
I request what type of super capacitors that will take to replace the
battery space of 12 inches high by 45 inches wide and 55 inches long to
drive a 7200 lb EV at least 10 miles. To be able to provide 180 to 300
volts at a maximum surge ampere of 300 amps.
They responded with a spread sheet that list 20 large modules that about as
large as two T-145's that have a output of 9 to 13 volts at 2700 farads.
You can also get them in a single unit which you can bank together your self
or get them in cell pack like a battery case has.
The cost quoted just for the super caps modules is $39,000.00. A high
performance DC-DC converter is use between the bank of super capacitors to
the load which level the load as the capacitors discharge.
The problem here is, my rig is could carry the capacitors, but there would
be no room for the DC-DC converter and all the other accessory equipment.
Need something like a bus which is shown above.
The PFC-50 charger could be use, as long you taper up the current from 0 to
the maximum ampere the charger and circuit is design for. This is normally
done with this charger anyway. These super capacitors can be charge at a
pad mount charging station up to 300 amps for a quick charge.

We drew over 6kWh from a 30kg pack multiple times during road testing
and the race (2008 NASC). The car transmitted telemetry data to
another vehicle, and that vehicle provided an interface for race
strategy, including battery energy. I don't have a nice test summary
with only publicly releasable data; if you think I'm lying, I'm not
going to try to convince you otherwise.
Note, however, that this vehicle is extremely efficient and has solar
cells helping it, so the average discharge was around 0.1-0.3C and the
peak discharge was just over 1C. These low currents mean that we saw
almost no voltage sag. Such low currents aren't possible in normal EV
conversions.

As Zeke said, NiCd doesn't have trouble with 100%. What makes you
sure that Lithium Polymer has this problem other than a broad
generalization that isn't universally true?

OH yes...
And i've ridden in it ;)
In fact, several people have converted a Trabant. The one locally to
me in Bristol, UK, is limited to about 75mph by it's owner. He says
it's wheel-spinning-tastic in lower gears. I believe it's the fastest
electric Trabant out there as he's kept the gearbox and gone for a
custom-wound motor. (Don't quote me on the last bit though). He's
implemented software limits to both RPM and top speed.
FlickrAlbum for it is here:
http://flickr.com/photos/anachrocomputer/sets/72157604747849759/
- A friend of mine took various photos of the Trabant during
conversion and subsequent trips.
We had a pub meet last weekend where the owner turned up. He's managed
to do something to the brushes after a stray piece of road-debris hit
it at speed. He's awaiting a replacement from the US. Since the
photos above were taken the car has had a re-spray. I've got a photo
of it on my blog :
http://aminorjourney.co.uk/wordpress/wp-content/uploads/2008/09/160920083192.jpg
The couple who converted it, Martin and Judy Joinson, are Trabant fans
and thought it quite fine to convert this particular trabbi.

I shouldn't have to say this, but when I saw 200 watthours/Kg, I mean
under real world operating conditions in a real world EV based on a mass
produced vehicle.

For example:
"Specially designed electronic motor speed controls are used to prevent
excessive discharge and subsequent battery damage. This is achieved
using a low voltage cutoff (LVC) setting that is adjusted to maintain
cell voltage greater than (typically) 3 V per cell."

It's only been 2 days of not-too-rigorous road testing, but the latest
rev of Logisystems 156V 750A PWM DC controllers appears to have finally
resolved the issues some of us were experiencing. So far I'm leaving
the throttle ramp and current limit at half mast, and have only given
the motor side brief bursts of 600A which makes the 4600 lb. lead sled
it's installed on get up and go rather nicely.

Yes, of course we respected these limits. Our circuitry enforced
undervoltage, overvoltage, overcurrent, and overtemperature limits
more conservative than specified in the battery datasheet, and the
cells still delivered incredible energy density.
Discharging the batteries too far below 3V will cause dendrite growth
forming minute internal shorts and permanently damaging the cell. That
doesn't imply that the cell will rapidly decay when the low voltage
cutoff is respected.

Then I'd like to see the real-world ultracapacitor that can get more
than 10% of this.
Even LiFePO4 has over 10 times the energy density of any real-world
ultracapacitor.
Here's some good data on the cycle and calendar life of A123 LiFePO4:

You could always salvage a gas-powered heater from an old Corvair.
Gasoline is really inefficient at moving cars, but makes plenty of good

I can see it now. It will be like day traders on the stock market.
They'll have huge P/U trucks that they fill with batteries so that
they can maximize the amount of energy they can hold, charge them up
at night (or whenever off peak is) and then sell back a ton of it
during the day(or whenever becomes on peak), when everyone's paying
more. This could become quite profitable.
But, if everyone did this, the biggest benefit would be an end to
brownouts. You have a peak load (AC startup, fridge, etc) and it draws
the excess off your EV which is right there in the garage instead of
pulling off the lines. The power wouldn't have to travel as far, and
would help load balance every home. Then, as soon as the startup has
completed, the EV could recharge off the AC, pulling much lower
currents.
Heck, if everyone did it, it might put an end to 'peak hours.' I know
it would help to decentralize the grid, which is something I strongly
believe needs to be done... of course, I feel that more people need to
generate their own electricity at home, as it's technically the
easiest energy to produce... We could have exercise bikes and
treadmills and rowing machines - by saving money on energy costs and
exercising at the same time, we could end the obesity epidemic and the
dependence on foreign oil (and coal power plants) at the same time.
Then there's passive solar, and windmills (where allowed) and hydro.
Heck, we could even have hamster wheels producing a little bit of power.
If we had a place to keep it all, there is very little limit to the
things we could do to create just a little bit more electricity.

Just what it says... looking for positive or negative (within the last
year or so... I've heard about the ThunderSky dead LiCo cell group buy)
experiences with the above.
I'm looking at 33 KWh of the 100AH sized cells, and I want to get some
feedback before sending a large check to a "rabbit hole where batteries
may / may not come out of".
I'm also looking to see if there's a ThunderSky buy in the next couple
of months so I can get a more recent price; I'm looking to place the
order sometime near the end of February (as far as I can tell)...

You can find links on the subject of vehicle to grid technology here:
http://EVtransPortal.com/cerip.html
Articles are linked at the bottom of this ongoing project page for EV recharging
information and resources.
Some suggested articles:
Vehicle to grid overview: Here is an overview of vehicle to grid (V2G)
technology that may have significant benefits for plug-in vehicle owners and the
grid.
(Google recharge link)
Vehicle To Grid Demonstration Project: Grid Regulation Ancillary Service With A
Battery Electric Vehicle
This is a bit old, from 2002, but this report by Alec Brooks of AC propulsion
was an early landmark in V2 Grid study.
Vehicle to Grid Power: University of Delaware Articles and Links (Headed up by
Dr. Willet Kempton a prominent researcher in V2 grid technology and economic
feasibility.)
There are a number of Peer reviewed articles on this link, including "Vehicle to
Grid Fundamentals: Calculating Capacity and net revenue"
I was at a conference last spring where Dr. kempton gave a presentation on the
potential for battery electric vehicles to earn several thousand dollars per
year for owners who would take advantage of "buying" elecgtericity during low
demand periods at low cost, and selling back to the grid during peak times, with
the ability to monitor the state of discharge to insure sufficient charge for a
trip home (based on user input).
One interesting point is that you don't absolutely have to have a "smart" grid
to do V2g, but it sure helps with taking advantage of the variability of
electric rates made possible by continuous monitoring of the demand and supply
cycles possible with a smart grid.
California is presently spending over US 1 billion to make their grid smart. In
some other parts of the country Utilities are taking a "wait and see what
happens in California" approach to investing in smart grid technology.
A good resource on smart grids is a newsletter http://www.smartgridnews.com/
If anyone finds additional articles for this EVtransPortal recharging
information project page please forward to info@... and I will

Hello Eric,
That's is about the same type I got from Sam's Club. I only use it to
pre-heat my battery pack by inputting the heated air in a port in the
battery box, when my EV is going to set outside more than 8 hours in 0
degree temperature. The temperature of the batteries read 120 degrees while
heating and 77 degrees after setting 8 hours.
In the passenger compartment, I use two under dash heaters which one is a
640 watt and 840 watt at 120 vac. I got these units from a auto parts store.
I use a on dash 30 amp 2 pole 3 position selector switch to either select a
fuse AC power from the main AC plug in. or even can plug these units in
with a separate 120 vac plug in cord.
The other position of the selector switch can be use to select a future on
board AC 120 vac to main battery inverter which are costly at this time. I
have no ideal what they cost now, but my unit back in 1985 cost about
$500.00.
So far for the last 3 years, all I had to do is to preheat the passenger
compartment for about 15 minutes, before I leave. I can get the temperature
to over 80 degrees if I want to.
I try the 1500 watt Ceramic Pro-Heater by Lasko from Sam's Club for
preheating for about 30 minutes and it was cooking. The car was at work at
20 below and the outside of the car was steaming. Defrosted and melted all
the snow off. It was like driving on a hot summer day. The temperature was
reading 122 F! at the high setting.
So I found I did not have to have it that high wattage heater for a
permanent installation.

If the Grid is set up for V2G I wouldn't want to have my expensive light
weight high tech battery pack cycled at the power companies will. I would
rather
have a large backup system in my house made of cheap golf car batteries.
Call it H2G. (sounds redundant doesn't it) The wiring is already there all I
need is a battery pack and some electronics. Let the power companies play with
my non critical power storage not the one in our electric cars parked at work.
I'd hate to get out early and not be able to go home.

The idea is you have a vehicle with a range of say 50% more than you
need on a daily basis. You then take a full charge at a discount but
offer up to say 10% of your charge back if the grid needs it. As soon
as the grid is ok again you charge back up. If you decide to go driving
at the low point you get 10% less range over what you might have had but
that should still be enough for your normal commuting needs. You
directly benefit from lower charge costs, the grid benefits from not
needing 'peaking' plants, you benefit indirectly from not paying for
those peaking plants. In a perfect world it's a win win scenario. It
does take some effort and buy-in to get there.

Some lithium batteries will have higher cycle life than you can use in
their calendar life. If so, any money you can get above the price it
cost to fill up will be profit to you up until you match the cycle life
to calendar life.

Sam,
Actually I just heard from the guys are building my car
http://utahelectriccars.com/ who said they had had installed my logsystems
controller (750 A; 20-144V) and it goes makes my little Plymouth Colt (
http://www.evabum.co/1974) go like crazy. A few little tweaks and I should
be driving my first EV very soon.
They also said they spoke length with someone at Logsystems and essentially
they have gone back to their old design on these beause they couldn't really
get upgrades they were planning to work. But this is 'third hand' info so
you now know as much about it as I do.

Are you joking? or are you just very very young? ICE's dont last for
ever, just look at all the wrecking yards.
When you start an ICE it is metal on metal for the first few seconds.
then it wears at 100x for 1 min, 10x for 10 min and settles down to a
constant rate after that. That is why 300,000 highway miles = <100,000
city miles.
I have owned/own
1973 buick leSabre Moms car, motor threw chain at 125K,
fixed that then tranny went.
1968 Ford Fairlane Tranny went at 100K, Motor was strong
beyond 250K miles. (from the time when ford stress tested motors and
broke them in for us)
1973 Opel Manta Sisters car, Motor blew, rebuilt but
never right, too tight only run for 1-2 min.
1973 Opel Manta Got it becasue of bad tranny,
1988 Mitsubishi Pu Only new car I ever bought, 2 motors
because I autocrossed and learned the hard way about oil pan geometry.
199x nissan nsx 1600 Awsome car, but It had a low air intake
and i sucked in some water and bent every rod in the engine
1956 International S1204x4 OMG, 7200lbs, ford v8 motor 12-18MPG. ate
clutches and axles, but I beat it up. (it could get the front wheels off
the ground)
1995 Pontiac Grand am only 20K on odometer when bought in 1997.
Lemon, lost head gasket and leaked antifreeze into oil, lost #5 cylinder
on way to moms 6 mothes later. Put in a 2000 malibu motor because the
solved the piston problem by then. Tranny went by 100K. Stock tranny is
dumbed down version, not rebuildible. Put in a Heavy Duty Dyno'd tranny.
And my 1987 300zx EV first battery pack replaced under waranntee, but
may of just been the cold weather. I blew up the motor and the fix was
under $1000.
compare to the number of motors I have been thru above! The 2000 malibu
motor was 1500, the mitsu first motor was 4K under warrantee. and 1500
from wrecking yard the second time.
All the ICE's have had starters, alternators, mufflers some multiple cat
converters and smog checks; and radiators. half had have fuel pumps too.
Not a one made it 100K on the radiators. (100plus weather) The grand
am has lost it's heater core twice.
I now have about 4 years on my EV and it has allowed me to keep my
house. I think once you look at the whole picture, EV's are cost
effective and can only get better. Remember, we are still comparing OEM
ICE to backyard EV.
I am waiting, but I don't honestly believe the auto manufacturers will
really come out with a simple, reliable EV. They will not release until
they have protected every bit and have scared everyone just enough to
keep them from opening the hood. They operate on margins of planned
obselecence and designed cycle life.

WROOOOONG
Capacitors have a heat cycle life and an age limit.
Addmittidly the high $ ultracaps are gonna have better construction but
I can't tell you how many electrolytics I have replaced in old power
supplies.
They are usually "Electrochemical Double Layer Electrolytic" capacitors.
Look into them, there are failure mechinisms.
You thought LiFePo4 had tight BMS reguirements? Look into the BMS need
for suoer caps in series.!

Joel,
There?s a unit called a "Kill A Watt". They cost about $35. Only
good for a max. of 15 amps though. Mine is a model P4400. Maybe they
make ones that can handle more amps. Mine has a digital readout and
shows any one of the following: voltage, amps,watts, Hz and Kwh.

I'm finding some online, but most of them cost more than $100, and I was hoping

In addition to Thors request, how many cells are people buying at a time? Is
there a certain minimum quantity a buyer should consider? After looking
roughly at my needs I was thinking about pricing a pack of 54 LFP100s. Is
this too small to buy on my own?

Edison cells, that is zinc and iron ( I think) were used in the NY Times
Paper delivery trucks used from 1905 to 1955 In an article in "Pop. Mechanics"
said they were still using same cells in the traction pack. They were stored
with a dead short of a bus bar across the terminals.

It varies what the "trouble" is. With flooded NiCads 100% (and way more)
discharge is a way of equalizing them -- shorting each cell out to zero
volts with a bolted jumper, then recharge the pack again from zero. It's
only a problem for them if you have some of the string dead, and others not,
because you get reversed cells, I think.

The gas heater you are talking about was made by Stewart Warner, called a
"South Wind" I think VW bugs had them as a factory option but they were also
an aftermarket thing.
You can still get them http://www.stewart-warner.com/

Edison used nickel and iron with an alkaline electrolyte. They were famously
long-lived. Modern NiMH batteries are really just an improved version of
these batteries.

Hi Guys,
Ive had good experiences with thundersky cells for my scooter in the past
year or so:
http://www.evalbum.com/1499
I also own 90 x lfp90s, which ill be putting into my mr2.
If you buy from a distributor such as everspring, you can order any quantity
you like.
If you want to buy from the factory, it really only makes sense if you are
building several cars.
I know to get the price really cheap last time ($US1.20/AH ex factory) we
bought, we had to buy around 35'000AH.
Btw, Thor, where are you loacted?
If you are after a group buy, its usually better to be buying with people
near you.
Im in Australia btw.
Matt

I have not looked at the truck yet, but from the pictures the body looks to
be in good shape. The owner said that is has a 20R. I have not found an
adapter for this one yet. There are several newer toyotas and s-10s, I may
look for one of these. Do you live in a region where you need to have heat
in your truck or is it a summer time rig?
