The chips don't have the transistor on-board, just a driver, so it can support 
a wide variety of outputs.  There are limitations on how big the transistor's 
gate can be because as the gate's capacitive load increases the transitions 
become slower and the current can exceed the driver chip's rating.

I thought we were talking about a 220V 3-ph?  Where did 600V come in?

I am not sure that this leaves all cells in the same state of charge. It may
be necessary to wait a while and let them settle down as it would with LA
cells.


 A simple way that comes to mind is to simply discharge the cells (FET
transistor + power resistor for each cell) until all the cells have about
the same voltage.

  Hey Seth an' EVerybody;

   IMPORTANT THING HERE!!!!! I THINK? Youse guyz that have worked on 
Saturns; Quick Question! I have pulled apart Toyotas and Jokes Wagens, Front 
wheel drive. The BIGGIE here is; Do the Saturn front wheel bearings preload 
by tightning the axle nut to hold the damn things preloaded and TOGETHER??? 
If you haul off, towing the car , NO axles,WILL the bearings literly fall 
apart?? I KNOW they will on a Sentra, Jetta or Prius, all cars I have done 
Front Wheel Bearings on. I THINK these front wheel bearing designs are 
generic?? QUICK, SOMEBODY coue us, Seth, especially. IF Seth puts a BOLT and 
Washers throiugh the axle hole to hold the thing together, sO the damn thing 
THINKS there is an Axle tightened to hold it together?Like, Seth, IF you can 
wobble the front wheel, the bearings are falling apart!!Like after only a 
few miles on the towbar.THIS IS IMPORTANT, SORRY FOR SHOUTING!!!!!!!!

   OK? I'm all wet? Hope so?

      Bob

What do you mean by drawing the pack down?  I can see that if you
discharge a 120V pack to 60V there is a problem, but momentary high
current loads that draw the pack down should not be a problem, right?
me

The resting pack voltage will be say 125 volts but when I draw say 380
battery amps the voltage can drop as low as 65-75 volts. 
This problem seems to be much worse when the ambient air temp has been in
the 20's or 30's all night.

Drop the insurance but keep the plates. That way you can just reinsure
the car and start driving again.

I have seen this EV and the one thing that jumped out at me was the little 
bitty charger for these big batteries.
I wonder if they could be suffering from undercharging? Have they ever had 
an equalize? (An AGM equalize)
I myself put a $20 Lowes digital voltmeter on Each of my Eagle Pitcher 
Batteries so I can see exactly what they are doing on both charge and 
discharge.
We put a lot of money into our batteries, give them each a name and get to 
know them.
Jack.

It all depends on what you're comfortable with... The "rule of thumb" is  
to limit sag to 1.75v/cell under load. If you have a high %SOC on a  
balanced pack then going to 1.5v/cell is probably OK. Racers aim for  
1v/cell (max power transfer), but that's fresh off the charger on a well  
maintained pack.

The real danger is reversing a cell. With a balanced pack and a high %SOC  
it's fairly difficult to reverse a cell. As %SOC drops, or if the pack is  
unbalanced, the chances of reversing a cell under heavy current draw  
(large voltage sag) goes up.

The Zilla will turn on the battery warning light when your pack voltage  
drops below the LBVI setting. If you hit the LBV limit, the Zilla will  
automatically reduce battery current to keep the pack voltage from  
dropping any further.

I'd set your LBVI warning to 1.75v/cell (189V for a 216V pack) and the LBV  
limit somewhere between 1.5 and 1.7v/cell (162-184V). Too high and you  
sacrifice acceleration, too low and you risk abusing batteries. When  
you're accelerating and the battery light comes on, you know you've hit  
1.75v/cell. On a freshly charged pack this is no big deal, but if you're  
nearing your range limit, you should lighten up on the go pedal. As your  
%SOC drops, the battery light will turn on with fewer and fewer battery  
amps.

For my T105 floodies, I have LBVI at 1.75v/cell and LBV at 1.58V/cell.  
Freshly charged, I'll hit my battery current limit (350A) before the pack  
voltage sags to the LBVI limit. After ~5 miles, the LBVI is reached at  
300A. At ~10 miles, ~250A will trip the LBVI. After 16 miles, it's  
100-125A. After this, my pack goes downhill pretty fast.

My LBV limit is pretty low, but I need 175-200A to make it up the last  
hill on my way home. If I increase my LBV limit I won't make it - the  
Zilla won't draw enough battery current. I really should insulate my  
batteries - in the summer I can easily do 25+ miles instead of the 16 I'm  
getting now!

HTH, Adrian

Be careful before doing this.  Check out your state.  In Maryland, for example, 
plates must be turned in to the DMV before canceling the insurance.  Not doing 
so results in a big fine.  A friend was in an accident a few years back, car 
was totaled. Insurance company had car towed to wrecking yard with plates still 
on it, and of course canceled the insurance on it.  When he recovered, he 
bought a replacement car, went to register it, and discovered old car had been 
disposed of without turning in the plates.  He had to go through the insurance 
company to find out where his old car had been taken, get a statement from the 
wrecking yard that his old car was indeed parted out, AND pay a fine of several 
hundred dollars - all before he could get plates for his replacement car.

I meant under ANY load, and I should have said 105V.

Freshly charged batteries that are new, or very well equalized can
possibly survive getting drawn down to 60V (on a nominal 120V pack).
But it's not a good idea.

Routinely drawing the pack down this low will pretty much guaranty that
one or more cells get's reversed.  This will drastically shorten that
cells life (if not killing it outright).

If you want your pack to survive for the longest possible time, do not
draw it down below 105V.  Brief draws down to perhaps 90V when the pack is
fiarly full are ok, but the problem with this is you get into the habit of
doing it and when the pack get's older even 90V might reverse a cell.

Of course once the pack is worn out and won't perform while staying above
105V, well all bets are off.  You might as well abuse it since it doesn't
have long to live anyway.

Of course if you don't mind replacing your batteries every year (or less),
you can do pretty much whatever you want to them.

I seem to have managed to avoid the 'Husted Tax' I was warned about.
something about paying a fine for every year a motor build by Jim was
gathering dust on a garage and not being used in an EV.

Motor is in the car!!!!!!

Here are some pictures of the adapter a locla machinist (and also
a friend's brother) made for me http://www.nn.cl/Autos/EV/Adaptador/

I should have some pictures of the combo in the car.

And yes, its a cluthless coupler. I hate clutches and tested the 
gearbox thoroughly by driving it for an hour without touching the
clutch (and shifting by ear, feel and syncro abuse) before buying
the car and had no problem at all. Its a very sturdy box and syncros
do their job.

Maybe I can get it done before winter.

for some reason I don't see the original message so I'll reply here.

Valence (I think it was the lead sales guy) said that a trickle 
overcharge will not damage the cells so that might be one way to balance 
the cells.
I asked specifically about 0.1C for an hour for every cycle and he said 
largely no effect.

MAN! it is so interesting how small these motors are compared to the original 
ICE.
 
If the highest level LIION batteries wer avaiable today, would a 30mpc pack fit 
into the same space as the original ICE for a eccono box 4door?

nasty business. did ampmobile misrepresent the situation as well?

even though he has wronged you so try to be nice to him. see yourself in 
his situation. don't threaten but perhaps calmly explain that what he is 
doing is fraud and a felony? and that this type of behavior will land 
him in jail. and if he pays you back what he can then you can move along

Content-Type: text/plain; charset=US-ASCII; format=flowed; delsp=yes

I'm thinking of putting together a little circuit board incorporating  
the following features:

- Pre-charge relay w/ proper voltage rating and resistor
- KSI relay with proper voltage rating
- Fuse for the above
- Reverse-slowdown circuit w/ adjustable resistance
- Latching relay for ICE-style start functionality
- Proper arc suppression for main contactor (i.e. not just a diode)

And maybe one or more of the following:

- DC-DC step-up relay (for those with 14.4V/12V selection jumper)
- Charger interlock relay (if I'm building it for just me, I'd leave  
this out since my Zivan has one built in)
- An ammeter/voltmeter connection, with fuses small enough for the  
sort of light wiring used for these
- Some kind of "coil economizer" circuit for the main contactor

This would incorporate a lot of the features that the Curtis 12XX  
controllers leave out due to their origins as forklift controllers.

Since a lot of these components don't have good automotive-friendly  
mounting and wiring options, people end up using automotive-style  
relays switching ten times the voltage they're rated for (and  
typically much much less current).

Three questions:

1. Has someone made a nice custom-PCB variant of this?
2. If I have one of these made, is there enough interest to print off  
a dozen or so?
3. Any features I've left off? Which of the optional features are  
worth including?

Thanks,

I'm converting a 1969 VW Fastback and am getting ready to bolt the  
motor up to the transmission.

I was able to measure the magic number (flywheel to mounting flange  
distance) on the engine before I pulled the flywheel, but as I was  
doing this I noticed that the crankshaft had about a quarter inch (!)  
of axial play. The tolerance for this is .006", which may have  
something to do with the engine not staying in tune for the previous  
owner.

The bottom line is that my magic number measurement is worthless. Does  
anyone happen to have this information written down?

Subject: [EVDL]  Fork lift charger for EV charging?
To: ev@lists.sjsu.edu
Message-ID: <[EMAIL PROTECTED]>
Content-Type: text/plain; charset=us-ascii


      I have a chance to buy a surplus walkie truck fork lift charger very
reasonably but would like to get some advice before taking the plunge. It's
a 38 amp smart charger currently configured to charge a massive 12 volt FLA
fork lift battery to 510 "battery ampere-hour capacity for 16 hour
recharge". The controller  can be jumpered to control output voltage to
charge from 6 to 36 cells. I'd like to use it on the 36 cell setting to
separately charge two 72 volt strings of 6 volt flooded  golf cart
batteries. 
      The controller automatically monitors the change in voltage and
current to determine the length of charge and ramps the voltage at 80% SOC.
Is this charger's controller likely to be too closely tied to what's
expected for a specific type of fork lift cells to be able to charge a 72
volt string of T-105's, for example or is the lead acid chemistry universal
enough to let it work ok? Is this charger too smart for my own good?
       
       Charger specs are here if you want check it out:

Not sure how high power is available for this but some power supplys I
have seen in equipment uses a 3phase transformer that has a 3phase
primary and a single phase secondary. Then the 6 diodes and a cap and
you have pretty smooth dc. You could always Phase chop the AC side using
zerocrossing detection and opto coupler feedback to avoid dc link
voltage and a high freq magnetic second inductor.

These batteries are 14 months old & still in prorated warranty. 
I've all ready had 3 replaced for free before the first 8 months. 
The problem is when the battery pack is full it won't sag below 110. 
When it's down to say 70 % SOC in this weather it won't produce the amperage
And then to voltage falls.
I need to test each battery I think I have a bad one. 
I had one test a little week about 2 months ago.
Thanks for all the help!
Neal


I meant under ANY load, and I should have said 105V.

Freshly charged batteries that are new, or very well equalized can
possibly survive getting drawn down to 60V (on a nominal 120V pack).
But it's not a good idea.

Routinely drawing the pack down this low will pretty much guaranty that
one or more cells get's reversed.  This will drastically shorten that
cells life (if not killing it outright).

If you want your pack to survive for the longest possible time, do not
draw it down below 105V.  Brief draws down to perhaps 90V when the pack is
fiarly full are ok, but the problem with this is you get into the habit of
doing it and when the pack get's older even 90V might reverse a cell.

Of course once the pack is worn out and won't perform while staying above
105V, well all bets are off.  You might as well abuse it since it doesn't
have long to live anyway.

Of course if you don't mind replacing your batteries every year (or less),
you can do pretty much whatever you want to them.

I have looked at the voltage of each battery on discharge but not after
charging.
That's an idea to try. I have never eq'ed them. Trojan says not to EQ their
AGM batteries.
My charger has a lot of room voltage wise. 
I can charge up to 170 volts. 
But only at 11 amps max. 
Too low??

mpc? mega parsec? cause that's too far :) if you mean miles then that 
would be around 70kg even with moderate density LiFePO4. about the size 
of 2 24-sodacan cases.

could actually make an interesting product to have motor, controller, 
dcdc, recharger and batteries as a bolt in replacement all in a case 
shaped like the combustion engine :)

it looks nice Eduardo :)

Message-ID: <[EMAIL PROTECTED]>
Content-Type: text/plain; charset="us-ascii"; format=flowed

Thanks to Milwaukee Tool, Jim Husted, and some good work by the guys at 
Lawless Industries the Monster Garage Chevy has almost risen from the 
dead. Yesterday I opened up the front GE motor and saw what amounted to 
a crime scene undisturbed since Bakersfield CA. I got a face full of 
fire extinguisher powder accompanied by various pcs. of brush gear and 
wire. Turns out we did a much better job of destroying the 11" GE than 
I thought.  As luck would have it I found an old GE surplus motor on 
the shelf that had a similar looking brush gear.  1 day's labor, some 
good advice from Husted, and some coughing and weezing later and the GE 
is up and running again.  Since we have 2" of snow and are leaving for 
FLA on Thursday, we all will find out together at BBB if it will hold 
together long enough for a couple of 1/8 mile joy rides.

AGNS will be tagging along to BBB as well sans the third wheel.  I was 
hoping to send her to San Diego for the west coast race but she has 
been rebuilt for 2 wheels again and is unfinished and completely 
untested with her new drive system.  It would be unsafe and unfair at 
this point to ask someone to push her to the limits before I do so 
myself.   I wonder if she can take MG in the 1/8th.  I feel a grudge 
match coming on.

See you in Miami!

Definitely check with your DMV.  In Louisiana, dropping insurance 
without turning in the plate also results in a hefty fine.  BUT, they 
do allow you to submit a "Statement of Non-Use" that declares that 
you aren't going to use the vehicle on the road for a specified time 
period (you can turn in subsequent ones if things take longer than 
originally planned).  If you have this statement of non-use on file, 
you are free to drop insurance and keep the plate.  

So ... check with your state and read up on all the loopholes that 
may be appropriate.

Good luck with your De-icing ... I'm about to start my own!

Hey Eduardo, how do you rate?  My motors are installed "IN" the car and Jim
is still charging me ;-)  Maybe you're just lucky you are outside his
jurisdiction, heh heh. 

But hey, now you got your motor  in the car watch out he might start
charging you child support (or more like psychiatric fees)  :-O  For all the
mental anguish he'll have to go through listening to how you are jamming so
many amps through and the baby is squealing like a stuck pig.

But hey you got your motor in  all the tax in the world ain't gonna do him
any good.........he can't even collect.......unless you give him a reason.

Congrats....lets see some pics once you get them.

Didn't Mike Moore from Ampmobile traverse the list not too long ago saying
he was doing conversions for LionEV?  I can't remember when that was to look
up the post.  Maybe you could contact him to see if indeed he did indeed
sever a relationship with LionEV and if he has any information to help you
file your case.

Maybe he's hoping for a more "conservative" milli-parsec. That should
last about 31k years at my local freeway speed. ;-)

I'm working on a 1971 WV Karmann Ghia.

The instructions that came with my Electro Automotive adapter say the 
distance from face of flywheel to face of adapter is 1.313" +/- .010".  
I didn't measure the magic number when I took it apart, sorry.

If you don't have an Electro Auto adapter this number is probably not 
very helpful, but it's the best I can do :)

I saw the original.  You can check the archives and see what's showed 
up or not.

I'd agree... cold batteries really don't perform well... I had a 200AH
AGM sitting at 11.1 volts today (pretty totally dead due to dead PV
array for the past few weeks), and started charging it with about 3.5
amps when I fixed the array -- and the voltage immediately jumped to
about 14.7 volts with only that small charging current.  The battery
temperature was around 15 or 20F.  I wonder if it was actually frozen?
 It's easy to tell with a floodie -- because the case bursts... but
harder to tell with an AGM.

I've used AGM batteries that were battery temp of 0F... and even fully
charged, 13.0 starting voltage at rest,  they would sag to under 12
volts with a 10 amp load (200AH pack)

Boy, I'd like some NiCad's sometimes....

Subject: [EVDL] Need to design BMS system for LiFePO4 cells - some
        questions
To: ev@lists.sjsu.edu
Message-ID: <[EMAIL PROTECTED]>
Content-Type: text/plain; charset=us-ascii


(this is a repost via nabble - I was not subscribed to the list when I first
posted)

Hello.

I need to design a BMS system for LiFePO4 cells.  I understand the
monitoring part completely - linking the BMS system to the controller to
prevent over-discharge and to the charger to prevent over-charge.  My
question is about balancing the cells.  A simple way that comes to mind is
to simply discharge the cells (FET transistor + power resistor for each
cell) until all the cells have about the same voltage.  However, it would be
nice to be able to take fully charged cells out of the series chain during
charging.  No simple way to do this comes to mind.  Am I missing something
-- are there some clever tricks I haven't thought of?  Relays or other
switches that bypass the cells are out of the question for my design.

Thank you,

Fran
