Hello to All,

I had written:

...after a nearly out-of-control crowd-roaring monstrous sideways burnout, Tim Brehm powered White Zombie off the line with both front wheels up, the car twisting and getting crazy mid-air...he blew up a battery right after passing through the 1/8th mile marker....coasting nearly an 1/8th mile to cross the 1/4 mile finish line...still managed a 12.9!



[EMAIL PROTECTED] responded:

Hey John!

I just love it!!!  I assume there is going to be video!  We need video



Sorry to say....no :-( We 'did' get the first race covered professionally by world renown cinematographer David Brill from the Australian television show 'Dateline', where Tim absolutely wasted a V8 Mustang in front of 800+ people in the stands :-) The second and third races were only caught with digital cameras. White Zombie once again turned 12's on all its runs...even when coasting!

One of the highlights was retrieving White Zombie more than a 1/4 mile away with the Heavy Metal Garden Tractor in the nighttime darkness. With the tractor's DC-DC cranking out 14+ volts keeping the twin headlights bright, and with the CD sound system's 8 inch sub pumping the bass, I came back towing the Zombie while Nickelback's heavy hitting 'Never Again' was playing LOUD! On the return lane that runs past the timing slip shack then immediately behind the grandstands, the race fans above me looked down to see the glow of the tractor's dash fitted with its Emeter's red & green digital display, the blue LED 'forward' direction indicator, the subwoofer power amp's LED indicator, and the vacuum fluorescent display of the Sony CD head unit. At least 20 folks at the top rung of the stands were dancing to the tunes, simultaneously amused at the towing power of the electric garden tractor 'and' its outrageous sound system...great fun!

I've been accused of grandstanding before...

See Ya....John Wayland

To be honest Otmar is the only game in town.  The only possible compeditor
is Logisystems in Texas with their 156v 800 to 1000 amp controllers.  I'm
not sure what the final spec's will be but if you want a well thought out
product that performs Otmar is it.  Logisystems does great on upgrades and
repairs &  I hope they bring the promise of performance at an affordable
price.  Their Controllers will be in the sub 1k price range.

You have a Curtis and expect to be "screaming down the road"? The
first step is to admit you have an addiction to electrified speed.

They don't use GC batts or Curtis, but they are also not looking for
the lowest price or longest range. Floodeds cost least per kwh; next
come sealed lead - the 12v/110Ah size from Universal Battery runs
~$100 each. SLAs will survive high current better than GCs.

A Curtis 144v/500a = ~75hp, but other than waiting to pay a couple
thou for a Zilla, look for used controllers (Auburn or DCP, both from
 defunct companies) on the EV Tradin' Post or eBay.

I take you havent read Elon Musk's business plan on this yet
http://www.teslamotors.com/blog1/index.php?p=8&js_enabled=1

They ARE going for 30K, eventually, but you have to start from
somewhere. And the math on acceptable batteries currently strongly
suggests starting at the high end.

Actually maybe it will do some good, if tesla,tango,AC propulsion listen
and go for 0-60 in 8 for 30K, maybe they won't be the butt of the
comic's jokes.

Let's just do a quick "proof of concept" on paper just to show it can
be done(for the fun of it!).

Assuming:

1) 500WH/mile
2) A 6000 pound, 500KWHr pack of Kokams...

The first 1000 miles is easy, but then you need a week to recharge. A 12 hour recharge would require a 220V, 190A charger! Can you say neighborhood brown-out? A PFC-20 could get you going again in just over 4 days.

Portable nukes anyone?

Let's look at replacing the 1600 pound lead-acid pack in a small pickup with Li batteries:

1) 300wh/mile
2) 5KW charger (23A at 220V - slightly better than a PFC20)
3) 12 hour recharge time

That means a 740 pound, 60KWH battery pack with a 200 mile range. Upgrade to a PFC-50 charger and you can top off a 1600 pound, 130KWH pack in the same 12 hours for a 430 mile range.

It looks like charging is the main obstacle here. A 5KW charger gives just under 17 miles/hour (of charging). At 10KW (think PFC-50!) it's 34 miles/hour. Compare that to a 5 minute ICE fillup that nets 300 miles (3600 miles/hour of fueling), the equivalent of a 1MW charger.

If you can afford the 1MW charger you can probably affort the 130KWH Li pack, but I don't think it would be happy charging for 5 minutes at 4000A. A 1 hour quick charge would still be over 400A with a 300V pack. I can hear it now: "Your EV only goes 400 miles and you have to wait an HOUR to recharge?!?!"

Swapping packs at the "charge station" would be much easier, but you'd have to have standardized packs, quality control (don't want that pack Wayland used on the track last year!), etc...

Has anyone actually seen the A123 batteries being charged in the five minutes ?
Is the five-minute charge even really possible ? From what i gather,
their chargers in deWalt powertools are using one-hour charger.

For a EV-sized pack you will obviously hit serious amp limits.

BTW, wasnt it reported that Tesla pack is built as sort of "RAID array
of batteries" so you can slide out individual sheets and replace them
one by one ? With some sweat, you could theoretically change the
entire pack in a few minutes, if its true.

Subject: RE: The math for a 1000 mile pack


Hello.

My EV ('93 Toyota p/u) uses 24 Trojan T-145s (144V), and has a range of
50mi.

I would love to reduce the weight as the batteries alone weigh 1700+lbs.

Does anyone have any suggestions for a maintenance-free, light weight
battery solution with reasonable cost?

I'd like to eliminate watering the batteries, and not have to worry about
hydrogen offgassing, and if able to reduce the weight of my vehicle I could
increase my range significantly.

Also my acceleration sucks. I'm usually passed by at least 6 or 7 vehicles
before I can get up to speed in traffic.

Is it better to hammer the pedal, draw more amps at first to get up to
speed, or take 'er easy and baby it up to speed taking much longer?

I'm running a Curtis controller, and ADC 9" motor, that I thought should be able to have my EV screaming down the road....? So either something is off,
or the weight in the bed of the truck is holding me back.

Not sure how the big boys are able to achieve the tire smoking power they
do.

Suggestions/thoughts?

Many thanks.

Curtis.

No need. Make standardized swappable packs as cordless tools.
You drill all day long but you don't wait for it it to recharge.
You stick in fresh battery and depleted one can charge slowly.

An EV is a big cordless tool. The second pack (and the first one
for that matter) doesn't have to be yours, it can be leased
and swapped at any "gas" station quicker than it takes to refuel
ICE. It's only a matter of establishing infrastructure.
There are no technical/engineering issues.

BTW, 500Wh/mile is about twice power consumption as average "normal".

To cover 1000 miles you'd need "only" 250kWh pack, but it is
drop dead 100%DOD at the end. Just 5% bigger pack would
give you extra 50 miles to get to the nearest swap station.

This has been discussed before. No one is interested to
implement it, people only understand dollars. No one will
do it even chocked to death from smog while gas is cheap
and available. Sometimes it's good when a govt can mandate
something [like this, or like ZEV], but it's dreaming.

We do what we can.

I agree! But how many people have an ICE that can go 1000mi between

I agree, but the ice refuel time is not that big of a deal compared to
a pack recharge.


EVers say "we can give you a car that goes 40mi, which is more than
most people go in a day", and the public says "maybe if it could go
100mi";


This is the resistance I constantly run into when vying for EV
acceptance.  A high 90 something percentage of the time, a 40 mile
range EV would fit nearly every ones needs.  The problem stems from
the ice owners current vehicle that has the capability to and has gone
on longer trips.  They feel "threatened" and scared by the thought of
someone taking away their gas powered car and replacing it with a car
that can only go so far between the hours it has to be on a charger
before it can go again.  Everyone I have spoken to about EV's is
terrified at the thought of "only" 40 miles of range.

But the idea of a 1000 mile range Lion pack in the back of an F150..
It's totally possible though right?  If I had the money, I'd build one
just to show the OEM's that look, yes it is possible and yes, it can
be done(have done it).

Since we're discussing 1000 mile range EV's, I would like to throw out
some more things for out if the box ideas.

In my opinion I still feel the way to go on an electric vehicle is with
direct drive.
We have already seen the performance advantages with John and Matt's
cars.
The EV1 was also designed as direct drive.
Eliminates more components that require maintenance; transmission,
clutch, etc.

Jim Husted or others;

What kind of crazy motor designs would be applicable to a direct drive
vehicle.

Are Siamese setup's the way to go?
Does 3 smaller motors coupled together offer any advantages?
Any easy way to have a motor at each wheel and eliminate the rear end?  
Any others?

Thanks;
Dennis

I'm not sure if David has mentioned this on the list yet or not, but he is
also looking to convert his 2wd Avalanche to 4wd for this conversion.

Can someone more familiar with this vehicle comment on the parts needed
for this conversion?

I'm thinking he will need to replace most of the front end of the vehicle
(suspension, hubs, brakes, etc.) and possibly have to do some modification
to the frame.

I have never ordered anything from Cloud Electric, so I don't know much about

If you can, could you elaborate on the "integrity and performance" that Cloud 
Electric lacked?
Just curious...

My opinion is that they are just sore since back when they were Cloud Electric 
they did not meet our standards for integrity and performance in order to 
become a dealer. From what I've heard, the name change has not changed their 
approach to doing business. 
 
And yes, Ryan is right. Our backorder list is long. Lacking affordable help the 
progress to filling it has been slow. I am working on a couple large batches 
now and hopefully in a few months we'll be doing somewhat better. 
 
Thank you to all of you waiting for controllers for your patience.

Umm, actually the EV1 has a transmission, a single speed transmission. 
Technically, so do John and Matt's cars, the single speed reduction is
part of the differential.

A drirect drive motor (one that spins at the same RPMs as the wheels)
would need to be fairly massive in order to generate enough torque.

I know of a few recent vehicles that have used multiple motors connected
directly to the wheels (or even wheel motors), but they were all VERY
expensive.

If you want to do an EV conversion to save money, forget it.  Payback period
is too long.

But money is only a personal issue.

But what about the other considerations?  What about reducing your personal
pollution and your personal impact on the environment?  How about helping
your country to become less dependant on oil and foreign suppliers?

Sorry, I guess people are getting hung up on the range statement.

Some claim good range, but then make a qualifier of 45 mph, etc. I don't
know about you all, but if I hop on the freeway (required for most traveling
in my area) I need to hit a speed of at least 55 mph. Heck, when I tow a
trailer I feel down right unsafe on the highway at only 55 MPH.

I'm not sure a true EV will be in my future any time soon. The cost and
performance is horrible. I'm fine cruising along with less power, no issues
there, but the range and economy have to be there. Part of the economy is
the cost of the conversion.

If you are using a FWD setup with the Electric motor connected to the
front hubs and they are Auto Locking hubs, won't they unlock when the
wheels spin faster than the motor?
If so then you could short the motor (to lock it) and the hubs will unlock
and you won't have to worry about over spinning the motor or the drag from
it.

That is, assuming that the front hubs unlock the way I think they do.

I don't believe this is true.
I don't normally drive an automatic, but as I recall, if you are driving
down the highway at 60 mph, and take your foot off the gas, the engine
speed will drop down to an idle while the car keeps moving at approx 60
mph.

Of course I may be wrong.  As I said, I don't drive automatics all that
often.

Sorry to say....no :-( We 'did' get the first race covered professionally by 
world renown cinematographer David Brill from the Australian television show 
'Dateline', where Tim absolutely wasted a V8 Mustang in front of 800+ people in 
the stands :-) The second and third races were only caught with digital 
cameras. White Zombie once again turned 12's on all its runs...even when 
coasting! 
 
One of the highlights was retrieving White Zombie more than a 1/4 mile away 
with the Heavy Metal Garden Tractor in the nighttime darkness. With the 
tractor's DC-DC cranking out 14+ volts keeping the twin headlights bright, and 
with the CD sound system's 8 inch sub pumping the bass, I came back towing the 
Zombie while Nickelback's heavy hitting 'Never Again' was playing LOUD! On the 
return lane that runs past the timing slip shack then immediately behind the 
grandstands, the race fans above me looked down to see the glow of the 
tractor's dash fitted with its Emeter's red & green digital display, the blue 
LED 'forward' direction indicator, the subwoofer power amp's LED indicator, and 
the vacuum fluorescent display of the Sony CD head unit. At least 20 folks at 
the top rung of the stands were dancing to the tunes, simultaneously amused at 
the towing power of the electric garden tractor 'and' its outrageous sound 
system...great fun! 
 
I've been accused of grandstanding before... 
 
See Ya....John Wayland

If you go to this link:

http://www.a123systems.com/html/tech/power.html

on the right there is a graph (click on it to make it
bigger).  I'll re-type the caption:

"A123 batteries can safely charge to very high
capacity in less than 5 minutes with low temperature
rise and no cell damage.  This chart shows the
temperature (orange curve) of a cell as it charges at
different rates between 2C (30 minutes) and 20C (3
minutes) and discharges at 10C (6 minutes) after each
charge."

The graph show temperature ranging between 25 deg. C
and 40 deg. C.  There is a voltage plot, I roughly
estimate it shows it between about 2.8V and 3.8ish V. 


I don't know the details of the test involved (was
there any cooling?  Ambient air temperature? Where and
how did they measure temperature?) but the curves seem
to back up the claim.

20 bux! It, unlike my #$%^& CD players, still works! I can live with the
miniture remote with a zillion buttons that really don't DO anything.

    Back to the point; sorta, the new stuff is pricy, I guess we could
consider the EV an "Electronic" gadget?Like a BIG HDWhatever screen TV, EVen
they are coming down in price, as pix size grows.60 an' 70 dollar VHS and
