This is a bit confusing. Let my try to explain it.

The current in a series string is the same everywhere. If the batteries 
were all identical, they would all charge and discharge identically.

But, they are not identical. There are always manufacturing variations, 
so each one has a slightly different amphour capacity even when new. 
That means if you started driving with all of them full, the weaker ones 
discharge deeper, and go dead first. Your range is limited by the 
"weakest link", i.e. the lowest capacity battery in the string.

The charge/discharge efficiency of each battery is also not the same. It 
varies between batteries, and more importantly, it varies with depth of 
discharge, temperature, and other factors. So when you recharge, the 
more efficient batteries will reach "full" first.

This creates a situation where the batteries do not stay at the same 
state of charge. On discharge, some get more deeply discharged and could 
even be damaged. On charge, some reach full first and get overcharged 
while others may not even reach "full". As the pack ages, these problems 
get worse.

The usual scheme is to deliberately overcharge by 10% or so. Stronger 
batteries that weren't as deeply discharged will reach "full" first. The 
overcharging lowers their efficiency, giving the weaker ones time to 
catch up. Overcharging also shortens their life and reduces their 
amphour capacity over time, which tends to "pound down" the stronger 
batteries to match the life and capacity as the weaker batteries. When 
the weakest battery dies, the rest of the pack will have been "beaten 
down" to match.

This is fine if you don't care about range, efficiency, or battery life. 
But what if you want to make that expensive pack take you farther, save 
energy, and last longer?

That's where a BMS comes in. Its goal is to individually monitor each 
battery, and see to it (by one means or another) that you don't 
excessively discharge or overcharge any of them. This extends the pack's 
life; often by 2:1 or more (enough to pay for the BMS on the first pack).

BMS that just shunt away excess charging prevent the damage from 
overcharging, but do nothing while driving to improve range.

BMS that shuttle charge between batteries while driving can also extend 
range, by preventing the weakest batteries from being as deeply discharged.

They aren't bad -- just worn. If this is due to lack of a precharge
circuit, add one and they should be fine for years to come.

Last time I bought replacement contacts, they were more like $15 (versus
$100 for a whole new contactor). Sounds like someone is gouging you on
the price.

You can be certain of this! It really stung to lose against the Z06 in 
front of so many racing fans, especially after the grudge match had been 
so hyped by the show promoters. To my surprise though, most everyone who 
rushed around the car as we had it on display in the bikini contest 
area, couldn't stop talking about how badly we toasted the Vette off the 
line...they loved the Zombie's launch! Rob, the guy with the Z06, is a 
cool guy...he pretty much knows we can beat him, knows we'll be back 
stronger than ever this year, and is ready to let us make our point.

Good questions.

(1) 15 lbs. psi on that run.

(2) No tubbing is allowed in the Pro Street NEDRA class we race Zombie in.

(3) Traction will be dramatically improved for '08 by the following:

    (a) Flared-out quarter panels allowing wider wheels and traction 
tires (flaring is allowed in Pro Street)

    (b) Wider wheels and tires, either the same style of BF Goodrich G 
Force drag radials we have had such great luck with, or all-out
     drag slicks (allowed in Pro Street). If we go with drag slicks, 
we'll still run street tires and drive the car to and from the track, 
but will      put the slicks on for 1/4 mile runs.

    (c) The biggest change...a for-real fully adjustable 4 link rear 
suspension (allowed in Pro Street), possible now because we planned
     ahead when we did the 6 point roll cage that included weldments in 
the rear area that created 4 link suspension mount pads. With the
     car's body dramatically stiffened by the 6 point cage, a much 
softer suspension can be used for increased bite in the back end. A
     softer suspension is only possible if the fender wells are wide 
enough to allow the tires to tuck up inside them while clearing the
     inside fender walls and the outer fender lips, both possible with 
the quarter panel flaring we have planned. Currently, the ~ 8 inch
     wide G Force drag radials now on the car, only clear the outer 
fender lips (barely) because we have a stiffly sprung back end
     augmented by air shocks that we adjust before and after racing that 
limit the vertical motion of the tire, preventing (most of the time)
     any tire scrape against the fender lips. We're hoping that after 
the above described mods, we'll be able to stuff 10 inch wide slicks in
     back.

    (d) Removable wheelie bars (allowed in Pro Street) for obvious 
reasons :-)

See Ya.....John Wayland

it seems that the more i research ADC, it seems that they have quite a
few unlisted motors.

Their website kinda sucks, there's no information there for their DC
as well as their AC. They should have cutsheets, vendor information,
torque curves, etc. There's nothing.

Does D&D have a website?

Measure the motor, not the tranny! it is much more accurate.

I started my conversion by trying to measure the tranny, what a waste of
time. The shaft in the center is not firmly mounted and the mounting
bolt holes were huge tapered casting holes to allow all that casting
slop. The motor on the other hand has been machined, I was able to get
believable numbers off of it.

If you want to start a library of patterns and you make it off the
tranny, it may be at either end of the tolerance spectrum, causing some
problems. for others.

I was thinking of this technique for wrecking yard trips. Take an 1/8
thick aluminum with a hole bored in it that fits nicely around the crank.
Use transfer screws in the block and clamp the aluminum in place, tap on
each transfer screw until it sits flush all the way around then take a
scriber an scribe the outline. Transfer punches for the locating dowels.

This plate can be then measured via a ball wiggler on a mill or even a
good scale.


The nissan had a thin metal plate between the tranny and motor, I was
able to get most the numbers of it.

As I went thru the numbers it became obvious that the nissan(v6) was
laid out in polar coordinates, ie there were two lines +/- 30 degrees
from the crank and all the bolts were equidistant of these lines.

Thanks to everyone that replied to my original post. From you I have 
learned:  A 30 hp 440 lb motor is way too large, go with 10-15 hp (150 lbs), 
maybe a 4 pole.  Pay the extra money for a flux vector drive. Lower the bus 
voltage and carry fewer batteries. Oversize the VFD 50-100%.

Based on your suggestions and comments  I have revised my plan:

1. 10-15 HP 208 VAC induction motor 150 lbs (3550 rpm but maybe 1750 4 pole). 
$200

2. 20-30 hp Flux Vector Variable Frequency AC Drive (VFD)[1] $1500-$2100

3. Series 24 12 volt batteries to produce 288 VDC for the DC bus on the VFD.

BTW, the Hitachi drives are speced to 400 Hz output.  They are available up to 
100 hp with a 230 VAC input (L300P-750LFU2). Even though most people 
run their VFDs from 1 or 3 phase AC, they can be fed from a DC bus.  
It is easy to do with no modifications.  Hitachi has a pdf that gives the 
basics.  Simply tie the inputs L1,L2,L3 together to the B+.  You move a 
jumper and run B- to another terminal.  A Hitachi field engineer told me the 
200V class drives have a bus overvoltage cutout at 380 VDC and a low voltage 
cutout at 200 VDC. Other than staying away from those limits, he thought it 
should work fine in an EV application.

If I understood another suggestion,  I could use a 1750 RPM motor and run it 
at 3550 RPM (120 Hz) when I need to do 60 mph. The bearings and armature will 
take the higher rpm as that is what is used in the 3550 motors. I really like 
this approach. Maybe it could direct drive the rear end and do away with the 
transmission? 

The Siemens-Ford AC motor on E-Bay looked interesting but it is $1900-$2000 
and needs a larger VFD than I can afford.

I have obtained a 2002 Chevy S10 with a blown engine - free for me to haul 
off . . . .

Thanks, I'll be back,

Anyone know how to remove the comm end cover from a Kostov 11"?  I removed
the bolts holding the end to the motor, but its still stuck. There is an
exposed snap ring on the shaft end and three allen head bolts around the
bearing.  Are either of those the secret?

Every time I do battery maintenance I disconnect the Anderson connector to
the charge circuit.  Every now and then I forget to plug it back in and when
I flip the switch on it goes immediately to a solid red warning light.  So I
flip it off, make the connector and turn it back on.  It wouldn't be a very
reliable unit if it couldn't handle an open circuit voltage, at least for a
few seconds.  

However in this case it wasn't open circuited.  It was still plugged in (the
Anderson connector) from a month of sitting.  I turn it on and I suppose as
the battery voltage started to rise it forgot to stop at the regulation
point.

  Subject: [EVDL] Conversion Shops



  As you may know, (or not, LOL) I have a (future) web site dedicated to 
commuter vehicles. Right now it simply forwards to my discussion on a EV 
cabinscooter idea. But soon the real version will go online. 
(www.detalidon.com<http://www.detalidon.com/>)
   
  I'm using it to advocate EV and SuperMileage commuting. I'm thinking of 
adding a section to support the EV conversion shops that are springing up.
   
  I notice it's becoming an industry to convert existing cars to EV. I'ld also 
like to address those leveraging EV into Extended EV with gensets etc. 
  I love the idea of trippleing the service life and doubling the financial 
usefulness of existing cars, by and upping the fleet mileage at the same time. 
I hate the idea of crushing a GeoMetro when a conversion to EV/Hybrid can cost 
as low as 5k.
   
  I'ld like to make that section into a catalog listing of services, consummer 
experiences and an E-zine. 
   
  Is there anything out there like that now? What do you think, should I do 
that?

  In the English version, it was pronounced strangely, making it sound
  more like "JigaWatts" than "GigaWatts." I think spelling it JigoWatts
  was just trying to convey the strange pronunciation.

The plate seems a lot easier then the adapter hub.  A taperlock hub or
something different?

Welcome back John :^D

It has been quite a while.

As one of the lucky few that have had the chance to drive the Zombie, I can say 
that I was pleasantly surprised by the ridiculous amounts of torque and 
acceleration it provides.

This was on city streets and I think the controller was turned down 
considerably from racing levels.

I suspect that the Zombie could beat any car you might find out on the streets 
in stoplight to stoplight contests.

A neck-snapping white-knuckle ride.
