AGM batteries can actually handlemuch higher charge currents than floodeds
since they don't vent and don't get pockets like gel cells.  I would assume
you could get away with a C/5 rated charge on them without hurting them.

So how should we treat these AGM batteries if we are used to floodies.

I am just about to put 36 new AGM's into my battle bus but haven't really
thought about the charging regime - it was just going to inherit the charger
from the old batteries and I was going to limit the current to no more than
C/10 (which is about 18 amps at 216volts) This is about all my 20 amp supply
can handle at the mo.

You CAN mount the AC system in the back no problem.  Just route the hoses
inside of a PVC pipe or something to protect them.

Subject: need better layout under hood


300zx project

I purchased 25 batteries but I only have 17 in right now.  13 in back
and 4 under the hood above the motor. I was planning on 8 more in front
but am having trouble fitting them in. If I get rid of my Air
Conditioning(AC)  condensor I could easily get 6 batteries and probably
mount the zilla above them then fill the zilla hole with #7 and the
stock battery placement with #8.  But Fresno is not known for cool
weather and AC is usually a must.

I hate to put any more in back because of weight distribution.

If I try to  leave the AC I can't see getting more than 4 more up there.

Would it be crazy to locate the AC compressor and condensor with fan
under the car in back where the gas tank was? and just route the AC
hozes up the tunnel? I suppose all kinds of rocks and stuff thrown up
from the wheels would take it out?

Another idea would be to lay it down flat up front and make a cowel. or
find a shorter condensor that can be stood up, the 300 zx condensor and
radiator lay down at an angle crossing the opening and really uses up a
lot of space.

My "research" mostly involved reading about what the overclockers (people who max out their computer performance) are using for their water cooled computers. Many of these guys leave their computer on 24/7, so pump reliability is something they're really sensitive to, since a blown pump means a blown CPU.

I just want to mention that this is not always the case. Almost any system made
in the last 3 or 4 years will either throttle down to protect themselves (P4), or shutdown entirely (Athlon with COPS). So not every overclocker will pick reliability over, say having a pretty LED on the pump :)

That's not to say that the pump you found may not the best for this job, just a thought about the premise.

<..snip..>


Point taken. There certainly is a lot of "pretty blinking lights" type of thinking in the O/C crowd. The pump in question is often listed as 50,000 hour MTBF The actual amount (from Laing) is 10,000 hours MTBF: http://www.lainginc.com/D_Series.htm The "Delphi" style pump by Laing _is_ rated 50,000 MTBF: http://www.lainginc.com/DDC_Series.htm Unfortunately, the Delphi pump is unable to provide 2 GPM.

Assuming you'll get 10,000 hours out of it, and assuming it runs 3 hours a day (generous, if it's only for the Zilla), then this pump will last you a little over 9 years.

I think in any water cooling setup, you should at least have a flow sensor switch hooked up to an "idiot light" on your dash. This is probably more important than coolant temp, because the coolant temp will be just fine in the event of no flow (assuming you're measuring temp at the tank), or (for that matter) no coolant at all.

Just from reading here and elsewhere (and by no means claiming an authoritative answer), I know that there are differing optimal charging voltages for the differing chemistries. Your new AGMs will like your old flooded's charger better if it has adjustable set-points for the various stages. If you have an intelligent charger, you might be able to adjust.

If you boil your flooded a little during EQ, that's okay, you can play mad scientist and add some distilled water from your beaker. Not so with your expensive AGM (or my gels).

You can get the voltages from your AGM manufacturer's docs, outlining the optimal settings. Whether or not you can reprogram your old flooded's charger is another story.

At the very least you might have a simple switch for Sealed vs. Flooded.

Have you measured your charger's outputs, i.e. laid a meter across while charging (at 2 or 3 stages)? Your new AGMs are precious babies, so I'd be watching the nanny (your charger) like a hawk.

Hi Bruce,

I believe that several non-operational electric Rangers were recently
auctioned off on eBay, by the Broward County Transit system, here in
Florida. They sold at least three that I know of, averaging about 7K
each. Buyers were eBay members zdogz, jhirwinirwin, and dickiedou2--

What I did when I bought my AVS buses, I contacted eBay members who
bought the same electric bus, and we created a mutual-support email
dialog. When I got my hands on the buses, I went around identifying
components, then searched (Googled) the next to see which suppliers were
still in business, and I started stalking support.

My AVS bus is Solectria-centric, but with a BMS/charger from a military
contractor who appears to have gotten out of the EV business (except for
an electric HMMV project that looks interesting). But docs can be found.

I would suggest that there are only so many square inches to that
Ranger, and only so many miles to the wiring, and only so many black
boxes, so I would work outward from the battery bay and find my
BMS/charger first, id the motor and controller, and then approach the
component makers for documentation on their individual systems. You'll
never stop looking for the shop manual for your EV Ranger, of course,
but if you had manuals for the components, the Ranger-only portion is
available as a Chilton's, and you'll be armed and dangerous.

One obvious suggestion is to make no modifications at all-- simply pull
all of the individual batteries from the bay, and try to nurse each one
back to health (like a bunch of chattering chicks in your garage), and
if those babies are truly dead, replace them with the exact matching
battery, in a full purchase.

Although a battery-pack redesign is always tempting, keeping the current
pack assignment would allow you to inherit the present value of the box,
the series connectors, the BMS, etc., assuming those are in working
order (your first order of business to change that assumption with
empirical tests).

Probably you would have the option to switching to wet lead if you did
not want the AGM (finding the same form-factor), but there would be some
parameter changes to program into the BMS/charger, I'm sure.

Also, I would suggest beginning with your 12V system first. Find your
12V aux battery and its DC-DC converter, make sure it is taking a charge
and providing aux power. Replace that one (or is it two) battery first,
if necessary.

You should be able to find test/probe points once you've identified each
of your subsystems. Depending on what safety and sanity-checks are
designed into your system, your BMS/charger may refuse to operate in an
undervoltage situation, or because the 12v is not there, or...

Of course, your life and your short hairs are in your own hands, and we
all are counting on you to keep one hand in your pocket, and to treat
any wire thicker than your short hairs with much respect.

Good luck.

I need some informational help from experienced people
and the Ford Ranger groups do not seem as informed as

I am about to drop the dead battery pack on a 1999
Ford Ranger EV.  And I know the following:
The pack voltage is dead.
39 AGM 8v 65 Ahr Delphi batteries in it. Weight
roughly 2500 lbs. Hooked up in series for 312Vdc pack.

Rear connector is power to drive system

Passenger front connector appears to be from Charging
system.

Now for unknowns yet!
Front Driver side connector. Dozen odd wires coming
out and where it goes.

Voltage requirements for following:
Air conditioning drive motor
Water Cooling drive motor
Power Steering Drive motor
Vacuum booster pump
Cabin electrical requirement for onboard computer
(presently assuming that is 12 volts from auxiliary
battery.
Voltage input to Lamda DC/DC.

Don't know what is in voled with BMS system.

What the present plans are include the following.
Drop the pack to diagnose the issue with it. Suspect
battery rupture as smoke poured out of it during last
drive. Or a loose connection splitting a post. However
it has been sitting almost 3 years so there is
probably little hope there is anything left of the
original pack.
Plan for build of a new pack. Suspect we will have to
build a new pack for it. This will mean redesign of
the pack itself with a probable need of a new Charging

to change the present system to accomidate a different

You ask a question of that company and you get send us
the pack you just hurt yourself working on it. I am
sorry I am an Electronic tech and work on 480Vac Water

what is issue with a 312Vdc pack.

Anyway back to my problem. I intend to bring this
truck back to life with or without assistance. If I
have to rip the whole electrical out and rewire it I
will. But I would prefer to leave it intact and
rebuild the pack. Just to get another EV on the road
again.
Thanks again for all the information: I am assisting a
friend to get his truck running. He bought this from
ASU and it was running when he bought it. However the

doesn't know anything about.

That is an AWESOME idea.  Until now I didnt even think of Rhino Lining my
battery boxes but now that you mention it that is an awesome way to
corrosion protect them.  If you want an AGM battery with the same AH
capacity as the Trojan T105 try the Concorde Sunextender series.  They are a
bit pricey but they will give you the performance you are looking for AND
the range.

Subject: Exide Floodeds vs AGM


I know I have beat this horse to death already, but I need some more
opinions here.

I haven't committed totally to my choice of a battery pack.  I have made
sure my battery box is capable of supporting and maintainence of either
AGM's or flooded, whichever I end up going with. Box is now finished except
the Rhino coat on the inside and I am good to go on that.

I have heard a lot of pros and cons, the AGM's of course being a lot better
on weight, delivered current,  required maintenance, etc, downside pickiness
on charging, extra cost intitially and pricey chargers, regulators, etc.

I have been looking at some Exide Stowaway batteries which would fit my
system, are priced well and readily available. Some are rated at 80ah.
Their big brothers are 105 and 200ah respectively.  Of course the real big
ones are huge as well.  Of course I know these AH ratings have a lot of
variables in how they are described.

So my question is....compared to AGM's which rate about 50ah, in the same
vehicle, won't any of the floodeds deliver better range at a sacrifice of
performance?

A lot of arguments are made both ways here about the low cost per mile on
floodies, the performance of AGM's, etc.  In my case I already have some
losses due to my automatic transmission and won't want to end up with a car
that only goes 10 miles on a charge.  This won't do at all with the cost of
the conversion.  The cost per mile using AGM's seems a lot higher if part of
your objective is beating the cost of gasoline.  I need 20-25 miles minimum.

The other factor is I can go with a Zivan charger, which was my initial
choice and no big hassles other than the periodic maintenance required.

Jeff,

Would it be crazy to locate the AC compressor and condensor with fan
under the car in back where the gas tank was? and just route the AC
hozes up the tunnel? I suppose all kinds of rocks and stuff thrown up
from the wheels would take it out?

I would say no, not crazy.
My Skoda Hatchback had an aftermarket air conditioner with the condensor & fan at the front where the radiator would be, the compressor /clutch / 84VDC motor mounted under the right rear passenger seat (where the gas tank would be on the ICE version) and on top of that, the evaporator/fan cooling unit mounted up on the ceiling in the back (since the car was not originally air-conditioned). Long rubber hoses connected everything together, including a pair passing underneath in the "tunnel". So it is definitely doable to set it up with a long hose run. If you are not an AC expert, it may be best to get the help of an experienced person/shop. I took this system out when it needed a refill after about 8 years, since I preferred the weight and space savings to paying to fix the cooling (in Montreal).

Best Regards,

Doug

You can make light of someone not caring enough about other people to be 
diplomatic all you want.

I'm here to tell you, the abrasive people will deeply hurt a dicission list.  
How many people will not participate?  You won't even be aware becauce they 
will quietly just not be interested any more.  In some cases the group could 
dwindle down to a half dozen or so members telling themselves how smart they 
are.  The group's "mission", its original purpose for being here won't be 
important any more.

Do you want to further people' awareness? How can you when people just don't 
care anymore to listen here?

Is it true that the Zilla's have over temp detection? If they do, perhaps 
you could hook that up to an idiot light. This would seem to be the ideal 
place to monitor the effectiveness of your cooling right?

Although, I guess you can never have too much monitoring. :)

--- Begin Message --- Don't know if it will help but one time on a Karmen Ghia I was doing a custom AC for I mounted 2 seperate 3 row condensers inside the front fenders below the headlights with a custom shroud on each and power fans pulling air from a series of holes cut under the bumper. Piped them together with copper line and hid the drier under the spare tire. On VW busses Mierline <sp> used a large horizontally mounted STEEL condenser underneath the van, worked even in AZ but was marginal. A power fan would have helped. Maybe something in the package tray area? Freightliners use a nice wide, low serpentine condenser you could put in a box. Would have to come up with a good intake and exhaust path (side scoops, in one out the other?) but where there's a will there's a way.

Would it be crazy to locate the AC compressor and condensor with fan
under the car in back where the gas tank was? and just route the AC
hozes up the tunnel? I suppose all kinds of rocks and stuff thrown up
from the wheels would take it out?

Another idea would be to lay it down flat up front and make a cowel. or
find a shorter condensor that can be stood up, the 300 zx condensor and
radiator lay down at an angle crossing the opening and really uses up a
lot of space.

Hi all,

This is a little off topic, but it does deal with motors and since there are 
some pretty knowledgeable motor people here...

I have a Jet 14" band saw with a 1 HP motor. It is for wood and I have a pulley 
attachment that lowers the speed down to about 1000 rpm, but it is still too 
fast for cutting metal (I've already ruined 2 metal blades). I want to get a 
Variable Frequency Drive. I understand that I can get one for about $150 and 
that I'll also need a 3 phase motor. I have 1 phase, 120/240 VAC to my shop. 
What are some good VFD's?

Thanks in advance.

Since the Zilla has 2 pot inputs, does that mean you provide the 5V and run a single wire back to the zilla for pot input?

They can emulate pots, so it seems like it should be possible.



Unfortunately, the Zilla requires a rheostat ...

I have kept quiet about the various insults and rude comments over the past
year or so, but I am getting a little tired over how much time is spent on
this off topic subject, and thought I would chime in.

How are these insults and rude comments helping us to promote EVs?  Not at
all.

There is no need to be gruff or rude.  If a person cannot be civil, then
maybe they should leave this list and vent their comments on a forum
designed for such things.

I have no problem with John's opposing viewpoints, his anti-environmental
attitudes, nor his generally gruff demeanor. I simply take offense to the
name calling and derogatory personal comments and characterizations he makes
on a very regular basis. Some feel that this kind of behavior should be
tolerated in the name of diversity. I disagree. Differing viewpoints can
always be expressed in a civil manner. Those incapable of basic civility
should be excluded from the conversation.

And if someone wants to make a joke, it is a simple matter and an
established custom to put a smiley face or something to make sure people
understand the comments were not serious. In John's case they were.

If someone who was KKK showed up and used racially charged derogatory
comments and name calling that is typical of their poor viewpoints of
African Americans and people of Jewish decent, there would be a huge outcry
and they would be shown the door without hesitation.

John's constant name calling and belittlement of those with differing
opinions is no different fundamentally and no less insulting...

Seems like the best price/performance is to be had with the Swiftech MCP-655 (Aka Liang D5). It's 12V, 1/2" barb connections. The only moving part is the impeller which is magnetically coupled to an electronic communtator. Think of a brushless DC motor where the rotor is actually a pump impeller. There is only 1 wear point: a ceramic bead bearing. You can see the internals of this pump here:

http://www.systemcooling.com/swiftech_mcp655-03.html

Near as I can tell, this is an industrial pump that's been repurposed for CPU cooling.

Slick looking pump.  I wish the temperature specs went a bit higher,
I'd have an application for hot water circulation.  It should do a
good job in this application.

FWIW, Laing is actually "Laing Thermotech." They bill themselves as "The Leader in Instant Hot Water Technology."

http://www.lainginc.com/

Google says products for sale here:

http://www.plumbersurplus.com/ProductList.aspx?Mfr=98

I think most of them are AC pumps.


Incidently, this pump is sold by the same folks (Swiftech) that make the radiator in the liquid cooling package that Ryan is selling. FWIW, the price of the cooling package that Ryan is selling is a good deal, even if for the pump _alone_, which seems to retail for $130 to (more typically) $170 to $200. If I didn't already have 80% of the parts in the kit on order, I'd think of getting one myself.

I plugged "swiftech mcp655 pump" into google and the first result was
apparently a froogle search.  The first three prices were all in the
$70 range.  Quite reasonable for a pump like that.

My personal preference for automotive use, especially EVs, is brushed
motors for small loads because I think them to be more reliable than
BLDCs with all the electrical crap flying around an EV.  Still I'd
give this one a try for the price.
I wonder what the Bosch unit is? What about electric fuel pumps or electric radiator fans? I really have no idea, but I had assumed they were brushless, simply because of the high duty cycle.

The Zilla manual states:

"The heatsink has two 3/8" OD barbed fittings on the signal end of the controller. Water flow direction does not matter. These fittings are intentionally fragile, and also easily replaceable. They are plastic in order to protect the copper heatsink from damage in case of abuse. In case they need replacing, be sure to seal the threads with Teflon tape and to pressure test the connections for leaks."

Am I wrong in assuming that the threaded ports are 1/4" NPT (tapered) fittings?

Are the fittings your standard nylon 1/4" MNPT --> 3/8" barbed fittings? Or are they something special to make them "intentionally fragile"?

I am using relays from cars for my EV. The nissan 300zx, and I am sure
many other cars, have a nice little box under the hood with 12V relays
in them
nissan has

grey      DPST NO,NC
brown  DPST NO,NO
black   SPDT
blue     SPST NO
 
They use 1/4 spade terminals and are sealed and the box is keyed to
accept blue type in blue holes if you want to get one of those for your EV.

They have the pin outs on the top but I have the book also

That is an AWESOME idea.  Until now I didnt even think of Rhino Lining my
battery boxes but now that you mention it that is an awesome way to
corrosion protect them.  If you want an AGM battery with the same AH
capacity as the Trojan T105 try the Concorde Sunextender series. They are a
bit pricey but they will give you the performance you are looking for AND
the range.

Subject: Exide Floodeds vs AGM


I know I have beat this horse to death already, but I need some more
opinions here.

I haven't committed totally to my choice of a battery pack.  I have made
sure my battery box is capable of supporting and maintainence of either
AGM's or flooded, whichever I end up going with. Box is now finished except
the Rhino coat on the inside and I am good to go on that.

I have heard a lot of pros and cons, the AGM's of course being a lot better on weight, delivered current, required maintenance, etc, downside pickiness
on charging, extra cost intitially and pricey chargers, regulators, etc.

I have been looking at some Exide Stowaway batteries which would fit my
system, are priced well and readily available. Some are rated at 80ah.
Their big brothers are 105 and 200ah respectively.  Of course the real big
ones are huge as well.  Of course I know these AH ratings have a lot of
variables in how they are described.

So my question is....compared to AGM's which rate about 50ah, in the same
vehicle, won't any of the floodeds deliver better range at a sacrifice of
performance?

A lot of arguments are made both ways here about the low cost per mile on
floodies, the performance of AGM's, etc.  In my case I already have some
losses due to my automatic transmission and won't want to end up with a car that only goes 10 miles on a charge. This won't do at all with the cost of the conversion. The cost per mile using AGM's seems a lot higher if part of your objective is beating the cost of gasoline. I need 20-25 miles minimum.

The other factor is I can go with a Zivan charger, which was my initial
choice and no big hassles other than the periodic maintenance required.

Hi David,
I have used the Robin Subaru EX21 210cm3 7.5HP (chain driven overhead cam) gasoline engine turning an eCycle MG1A-30 or MG1A-36 BLDC motor/generator fed into a 3-phase bridge rectifier. This provides about 4.5KW of DC directly at the battery pack voltage (84 or 96V in my case). I have also built a more powerful DC generator using a Honda GX-670 V-twin 24HP gasoline engine and a larger eCycle unit and 3-phase bridge. This one produces about 13KW of DC output. When it is needed, for example, on the highway on a longer trip, I turn on the key switch and press the start button on the control/meters panel, in the cab of the mini pickup, as I am driving. This start-stop control could be done automatically, but the generator is not used often enough to make this worthwhile for me, considering how easy and convenient it is for me to control manually when and where it is used. I would certainly look at the Robin Subaru V-twin engines for a larger generator, considering the quality that I have seen in the EX series of singles up to 9HP. I like the idea of a Diesel engine fueled by bio-Diesel, but could not accomodate the higher weight.

Best Regards,

Doug

Subject: Backup generator or true hybrid


I have my converted Diahatsu running again now. The clutch friction
plate spline had been chewed out by the gearbox input shaft. There was
only about 40% engagement of the spline.
The decision I have now is whether to have a backup generator or a true
hybrid. If backup, a cheap & nasty inefficient set may be used but if
true hybrid I have a 400cm3 Robbins Diesel I may use. What have others
on the list used?

You can try a router speed control.  I used it on my drill press to lower
the speed below the 600 rpm speed it had.  It works to about 50% then it
will not slow it down any further.  It had no effect on power for my use.  I
got it for $25 on northerntool.com

Same here on my 1980 VoltsRabbit.  I'm going up and down hills
all the time.  You get used to it.  But now that I have the
vacuum assist scene working, I'm much happier with power brakes.
Makes me wonder about doing power steering for low speeds, but
that's a whole 'nother can-of-worms...  sigh...
