I just had some problems with an undersized pump and a no fan
radiator.(tranny cooler) It had lasted a year but I noticed that when it
was warm, the zilla was fine untill I get to a light, then pulling away
from the light it would go into thermal protect(just about snapped my neck)
BTW, Isn't that pump from ev source awsome!
I went to that pump and switched to the smaller radiator like he had on
his site and added a 120mm 12V fan. on the lowest speed on the hotter
days, after finding all the red lights on the way home. It overheated
once. I turned the fan up to speed two and all is well now. Doesn't even
get warm to the touch.
Remember this
if running adds 10W/min of heat and accelerating adds 100W/min of
heat if you are adding 150W/5min and are pulling out 30W/min you will
not overheat, but if you are only pulling out 29W/min that extra
watt/min will acumulate. The next stoplight the temperature difference
in the zilla heat exchanger is less so more flow will be required to
take out the watts of heat and the watts of heat from the last cycle. It
can get out of hand pretty quick. The fan lets the system catch up the
pulses of heat from the accelerations at the stoplights when you aren't
moving air past the radiator.
You need it.

Or Mail a printable Entry form in with the set price of the raffle ticket by a
certain date well before the EVent. (You might
reveive entries after the drawing so you'll have to return those - or keep
them) Sales of new tickets during the EVent get added
to those received by mail ... The drawing could be made at the EVent and
Wildman could send an online play-by-play of the drawing
so those of us at home know when we win :-)

I'm coming along with my project, and got to thinking today about insurance
prices, and how they might differ vs. my Saab.
I just had a couple questions: What kind of coverage do you have on your
vehicle? What company do you use? How much do you pay?

Jukka,
Hopefully you've learned to ignore all of Dan's posts now? It's quite
clear (at least to me) that Dan has no intention of ever doing anything
except insult people.
He suckers you in with a seemingly honest question just so he can insult
you when you reply.

The diameter of the PCB is 73.5mm, diameter of the analog bar
(outer edges of LEDs) - 58mm. Outside diameter of the enclosure
globe - 79mm. I will update web site with this info and more
detail photos.
John and few others asked to describe features set. Here is quick
rundown for those who haven't looked on the web site:
Measured and displayed parameters:
Traction battery
* Instantaneous voltage, V
* Instantaneous current in or out, A
* Instantaneous power in or out, kW
* Current capacity, Ah
* Current energy, kWh
* Current SOC, %
* Current temperature (highest of 2 zones), ° C
* Indication of direction of battery current, OUT (drive)
or IN (regen or charging)
* Cycle life counter, full cycles
* Battery imbalance detection and measurement
Auxiliary 12V battery
* Instantaneous voltage (V)
Vehicle
* Current vehicle speed, mph
* Energy consumption, Wh/mile and/or miles/kWh
* DTE (Distance to empty) estimation
* TTF (Time to Full) estimation in charging mode
* Indication of charging status (in progress and completed)
* Stock analog fuel gauge driver
* Night time display and HMI dimming
* Sleep mode with wake up on ignition, HMI activation or charge
* Automatic drive/charge/idle mode detection
* No power consumed from onboard auxiliary 12V battery.
Instrument
* Streaming running data out from the galvanically isolated
RS232 serial port (NMEA ASCII format)
* Download and Upload instrument configuration parameters, user
preference, battery and vehicle parameters
* Long retention of internal RTC setup for correct time stamping
without power applied (~ 1 week).
Optional functions are (not implemented in the software yet):
* Tire pressure measurement, all 4 wheels, PSI
* Cruise control
* Power steering control
* Charger, BMS and other subsystems control via I/O expansion module
EVision consists of at least 4 sub-blocks - main controller, HMI (remote
user interface via rotary encoder) shunt measurement PCB and display.
Optional speed sensor is required for efficiency and distance estimation
calculations. Inter-component communication is implemented via CAN bus
(CAN2b protocol, 500 kbps, extended frame IDs).
Front end measurement hardware is based on BRUSA Ah counter shunt and
measurement PCB to maintain backward compatibility with legacy BRUSA Ah
counters. Thus existing BRUSA Ah counter owners can keep their
measurement board with shunt and upgrade only EVision display and main
controller. Display comes in 2 flavors: external in a spherical
enclosure and internal - without enclosure (for in-dash integration).
12V auxiliary battery voltage is monitored, but not used to power
EVision. In fact 12V power doesn't have to be present for proper
instrument operation. The power is supplied directly from the main
traction pack and the power consumed is about 2 W in running mode and
about 300 mW in sleep mode.
Relative SOC level is also outputted through the analog gauge driver as
PWM signal.
1 US models use Imperial units (distance - miles, speed - MPH, tire
pressure - PSI). EU models use metric units (distance - kilometers,
speed - km/h, pressure - bars). Computed values and correct units such
as Wh/mile for US or Wh/km for EU are displayed accordingly.
2 Speed sensor required for accurate energy consumption calculation.
If no sensor is present, default value user inputs during configuration
(say, 230Wh/mile) will be used for calculation of DTE.
Provision for Peukert correction is in the software, but this correction
is not implemented. Instead I use usable capacity concept and straight
Wh consumption calculation. User declares how much capacity he allows to
use and this number is assigned to 100% available capacity.
For instance if you have 50Ah battery (at 1hr rate) and don't want to
discharge deeper than 60% DOD, declare to EVision you have 30 Ah
"usable" capacity. Then, when the battery is full SOC=100% and by the
time 30Ah consumed SOC shows 0% (Ah shows 30Ah consumed) 50Ah is not
"visible" since you don't want to go there. (You can if you have to,
EVision will remain at zero SOC and Ah keep counting).
You can observe any 3 of about 20 monitored parameters at once.
2 with digital readout and one with analog bar. Actually, if you
assign analog bat to display something other than SOC and use stock
fuel gauge for SOC, you can observe 4 parameters).
You can pre-store 20 favorite combinations of any 3 parameters,
(pages") and flip through the pages by rotating encoder button
CW or CCW.
Configuration of pages, alarms, vehicle parameters (wheel diameter,
speed sensor teeth amount), pages, battery parameters and all defaults
are downloaded using simple GUI, but also can be downloaded using any
terminal software (Windows hyper-terminal or Mac Z-terminal).
Main electrical characteristics:
Model M2-RG-US, M2-RG-EU M2-BW-US, M2-BW-EU
Display color Upper digital - green, Upper digital - white,
lower digital - red, lower digital - blue,
analog bar - yellow analog bar - white and blue
As of now only red/green/yellow US version is being made.
Measured battery current range (0.01...250A or 0.02...500A in or out
standard. (Wayland's version is special - 2,500A max :-) )
Custom shunts for higher current readout are available. High current
measurement is available at the expense of loosing accuracy on
the low side (charging).
Resolution - 1V on display; 0.1V (I think) out of data port;
1% of the top scale basic accuracy.
Current measurement resolution (100A shunt): 10mA up to 10A,
100mA up to 100A and 1A above 100A, but LSB is not very meaningful
since 1% accuracy is dominating factor. For instance 300V readout
will be up to +/-5V (which is ~1% of 512V top scale).
Measured traction battery voltage 60...512 VDC
Measured aux. 12V battery voltage 0...16 VDC
Measured traction battery capacity 0...999 Ah
Measured traction battery energy storage 0...999 kWh
Measured traction battery relative SOC 0...100%
Measured traction battery power 0...650 kW
Measured temperature -35°C...+99°C,
hottest of 2 points,
Measured battery imbalance 0.5V resolution
(lower half vs. upper)
Full charge cycles counter 0...65535 cycles
Driving efficiency (energy consumption) 0...999 Wh/mile (US),
0...999 Wh/km (EU)
Power supply current (from traction pack),
running mode, no optional expansion module: 6 mA @ 350VDC or
20 mA @100 VDC
Alarms can be set for over/under voltage, over current, under-voltage
of auxiliary 12V battery, under-temperature.
The power steering output actually is not on present model but is
on the next PCB rev. One can modify existing EVision to take advantage
of it when software is in place. It has 2 modes - logic transition
when pre-set speed is reached (cuts out steering pump) or PWM output
reducing duty from near 100% to 0% as speed increases - this can
be fed to the amp running steering pump motor. The motor will
gradually reduce speed as you move faster reducing power assist.
Basically this is it, I can answer specific questions if
anyone has them.
Ah, the price: $550 for the first 10 units to get going (few are
pre-ordered already) and $775 after that. The shunt of your choice is
extra: 100A (0-150A measurement) is $36; 200A (0-500A meas,) is $48
and 500A (0-2,500A meas.) is $69. This info is on the web site
(on the price list).
If you already happen to have BRUSA counter, you pay $215 less by
re-using its shunt and measurement PCB.

'91 ACRX - something different
p.s. I can use help of someone who knows how to write scripts
for reformatting ASCII text (perhaps Perl be the best, but makes
no difference) - actually all people will benefit from it.
The task is to take captured ASCII output and reformat/align
columns of data so that when imported into excel template,
excel produces plots of meaningful parameters. Best script
writer will get $100 discount if he/she wants to buy EVision :-),
but the utility should be made available to all for free.
I will provide samples of the captured output.
Any volunteers? Please contact me off list if you care to
enhance usability of this gadget.

Hey Victor
If it can survive Wayland you're golden 8^) I'm
guessing you or Tim put it in or he'd have broke it
already ;^)
Congrats on developing what looks like an awesome
unit, I wish you much success with it and it's a total
win, win, for both you and EVeryone with an EV.
Anyway I just got this picture of you as you

I agree with you, Bruce. I have a dial-up connection that normally connects
as a fast 28.8 speed. This is the best that I can get since I live out in
the country where cable and DSL is not available. I, for one, like the
email format because of this. I just get on-line, open up my email and then
go off and do something else until the emails load. While I am sure the
on-line forums have their place. I hope that this email list continues. I
have been able to build my first EV and put it on the road in less than 4
months with no previous experience. Most of the help that I received was
from the good people on this list. I also like the ability to delete any
email that I object to, because of language or the content of the email. I
do find that some people on the list tend to take things too personal and
get offended too quickly but that will always be the case. I normally do
not write or reply to many of the responses on the list because there are
more people on the list with a lot more experience that I have. I am glad
that we all have alternatives such as the email list and the on-line forums.
It is our choice as to what we want to use. I will continue to use the
email list as long as it is available.
Thanks, Freddie

Guys this comes up every few months. And Al there is
an issue. Do you read the list from a dial up modem.
Some of us due- not me personally but it has been
talked about. Have you visited a Web based forum with
a cellphone and internet's connection. The Email
based sessions are much easier to read on email verses
web based forums because you have to search for what
your looking for. Email is straight forward.

Do you really think so? Next time you are on a forum, select a short
message and then, from your browser, select "view source" and have a look
at how much code you have to download to see that little two or three line
message.
Add to that that you usually can't tell if you really want to read a
message until after you've opened it. Many people aren't very good at
creating useful, informative, subject lines.

Now.. the chemistry also depends on the electrolyte. There is no way you
can check anything with a voltmeter. Sorry.
For example TS LFP (LiFePO4 cells) are charged to 4,25V .
Heck they have a common electrolyte cell with 4 individual cells inside.
So electrolyte can take up to 17 V !!
The electrodes of certain cells are mixtures of various substances.
There are millions of ways to mix things and at what point you say the
magical words changes the game again. There are just too much variables.
I'm now wondering why we are getting two different versions out of A123
about the cell tech ? Something does not add up here...
When I get something else than Nano-Phosphate-BS I will believe it. Now
all you lurking A123 guys on the list.. chime in ;)

Jeff Shanab kirjoitti:
I had talked with them early, when they would talk to us normal people.
and Since then,via email, to the factory in china that claims to make
the cells for them until they get their own plant going and in both
conversations they have said Lithium-Iron-Phosphate.
But it is easier than this to check. Get out your voltmeter.
Lithium cobalt 3.6Vnominal 4.25Max charge
Lithium Iron Phosphate 3.2-3.4 3.7 max charge (Easy to tell)
Lithium-magenese 3.7-3.8 Nominal 4.2Max charge (ok, hard to tell
compared to cobalt)

My Appologies to the list. I ment to send that to Jukka directly.
Sorry.
Jukka,
Hopefully you've learned to ignore all of Dan's posts now? It's quite
clear (at least to me) that Dan has no intention of ever doing anything
except insult people.
He suckers you in with a seemingly honest question just so he can insult
you when you reply.
Dan, I was not speaking in here. It's called typing or writing. That's
how the small little letters do appear in your 386 SX + CRT ... OK..
I have bought over 1 000 000 AH from TS up to this date. So.. yes I have
bought some.

Guys, Guys.. A123 sells Cobal Phosphate cells to DeWalt. They have not

from the little birds :) . . . .
that's interesting. their website doesn't actually say cobalt or iron.
but it does say the specs. it could be crystal meth chemistry for all I
care if it works. and apparently it does.
Selling plain cells to "grass root activists" is insane.
you really are a schmuck. haven't you yourself bought lithium batteries
for a homebuilt EV? such elitist crap
Reason A123 still has good fame is that they are not giving the cells
out to wrong persons.
aren't they selling to everyone? just at higher prices. when you learn
to speak english properly we can talk about who's the wrong people.

We are talking blueberries and strawberries here.
Plain text is most useful for reading EVDL with PDA or cell phone of off
line. The formatting to certain screen sizes makes it PAIN to read with
small screen. So plain text to these users please.
On the other hand the web based systems offer more cream on the cake.
With strawberries. (eh..) More functions and eye candy. But all the
mambo jambo requires the user to be online. With good bandwith.
I believe both parties can have what they need. Systems that work in
both worlds has to exist already.
Was there a survey some sort some time ago .. Can't remember what it was
about. But could we just see how much active users are on the list and
who wants and what.
If there is no free and available resources to do this I would gladly
pay something to someone to get it done (20€ or more if required). If we
do this together we could end up having something extraordinary. (Am I
dreaming again... ??)

The facts are:
- Most people on this list would like to see EVs go mainstream.
- Allot of people on this list have no idea how to search the archive or
where to go to do it, nor do they wish to take the time to figure it out
when a web forum offers the convenience right in front of their faces on

Howdy Bart.
I'm with Allstate. They sell a "stated value
policy", so that if I get totaled, I get the $8,500
cost of my on-board charger, batteries, controller,
DCDC, etc., not the $3,000 a gas-burner Civic is
worth.
It merely requires that I have saved receipts and can
prove the value is correct. I keep the same 50/100
coverage or whatever we currently have. It costs me
the same or less than a regular policy. You are wise
to ask.
peace,
