I wonder if we should depend on color at all. Perhaps on large cable,
white with black lettering like HV+ HV+ HV+ or HV- HV- HV-
down the wire repeating would make it both noticable and prevent wiring
errors. maybe + a little lightning bolt graphic + ....etc.
I would guess that colorblindness is not screened for on emergancy workers.
With 8% of the male population is colorblind (5% asiatic and 3% the rest
of us males) There must be a few colorblind emergancy personel.
I have a monitor with the red gun out I haven't got arround to fixing,
and that is where I happened to open Victor's under hood picture. I can
of course see the white wires with the black stripes better than the
orange wires to the charger. Most color blind people are red defficient.
...orange = brown :-(

There are no regulators on individual batteries.
An ideal regulator would return excess energy to the pack rather than
dissipate the unwanted.
I have voltage logs now. I did a test run of 50ks inc 10 ks @80-100kmph.
The batteries only started heating up when I got home. The batt has lost
capacity now.
Thanks Lawrence for your advice.

Lee I really don't understand why you are fighting this so hard.
WHy the Automakers choose orange is totally irelevant, who cares? (other
than you).
The fact is that they did and currently rescue workers are trained to
recognize orange wires as hazardous.
If you are building a conversion now, it makes sense to take advantage of
this, it does no harm and may possibly help someday.
Since we can't see the future, what difference does it make if they choose
to change it again in the future? We can only act on what exists today.
Suggesting that we as hobbiest develope a new standard is almost
ludicrous. How many standards have we set that anyone outside the
comunity knows or follows? And what would be the point?
Is there some other collor you have in mind that is somehow better than
orange? Is it worth the effort to educate rescue workers that "Orange is
dangerous in hybrids, but you have to look out for purple with pink
poka-dots in conversions"?
Let it go Lee, it's fait accompli.

Read carefully. It says "Hookup wire and service cord is stocked for 300
volt and 600 volt applications." NOT automotive wire! Hookup wire and
service cords are sold on a DIFFERENT page.
The SEPARATE box describing automotive wire does not give voltage
ratings. That's because the voltage rating specified for all types of
J1128 wire is 25 vac or 60vdc maximum.

Now, your spool might say 600v; but they can write anything they like on
a spool. It isn't UL listed; nobody tests it. It isn't required to meet
SAE J1128; it only has to work to 25vac or 60vdc. Besides, SAE specs are
voluntary; there is no independent testing. You have to take the
salesman's word for it, or test it yourself.

I think you are mistaken. Automotive wire is NOT a good choice for high
voltage wiring in an EV.

By the time you add the weight, extra tire drag, a
little aero drag and you wouldn't be able to tow a
trailer, it's little more eff than a series hybrid and
a series hybrid is much more simple, easy to install,
remove, weighs much less and as it runs always at it's
most eff rpm, very eff.
Plus a bike transmission and clutch just won't hold
up to pushing a 1500+ EV and itself. Then there are
cooling problems with it behind the EV. And the cost
as this must be new to be sold as an option.
Eventually it will be an under 100lb, 9-12kw
removeable gen in the long run I believe better
overall. The difference will be getting 100mpg vs 120
mpg or less.
The eff lost is quite small when everything need to
do either the direct drive or MC pusher is used.
Eventually our e motor, gen will be 90% eff each
even if we have to build them ourselves which we
probably will do later as the ones out there now are
too pricey.

Can't you adjust the timing to be correct at 100
amps, 80vdc? I have no problem moving the brushes to
get it right and will only be used as a gen except to
start the gen motor..

Yes it does so that's not good.

Hard to connect to the wheel with the trailing arm
movement. Can be done but not easy. Plus you lose some
eff in the belt, ect.

(How did I get myself into this mess...)
Everyone seems to think that I'm arguing about color. I'm not. I'm
saying the color is NOT IMPORTANT. Safety and performance are what
matter. It is more important to use the right TYPE of wire for the job;
not what color it is!
As to why I'm "fighting it" -- I reject the notion that the auto
companies are experts on EVs, or that they have any right (or even any
ability!) to set standards for them. It is the EV INDUSTRY that sets the
standards, just by plain old everyday usage -- not the auto companies.
If they're not in the market, nobody will pay any attention to their
"standards".
What's the standard battery connector? The Anderson connectors.
What's the standard EV charging connector? An ordinary 120vac 15amp AC
outlet already found in every home.
What's the standard EV battery? The 6v golf cart battery.
What's the standard EV motor? The Advanced DC series motors.
These are the standards because they are the most common, and most
widely used. They will *continue* to be the standards, until something
demonstrably better comes along; enough better so *it* becomes the most
common and widely used.
Only in rare cases can a company dictate a standard by brute force. It
only happens when that company has VAST amounts of market control and
plenty of money to spend. Gang, this does NOT describe anyone in the EV
market!
If orange HV wiring is a good engineering choice, let's use it -- on its
own merits. Just don't use it because Toyota or GM or some car company
says so.

You misunderstood me. I mean REPLACE your trailing arm and rear tire
with a motorcycle rear end. It's still a 3-wheeled vehicle; no trailer.
Either the electric motor or the ICE can drive the chain (or belt, or
even drive shaft) to run the back wheel.

There are bikes that weigh this much.

Just requires enough air. Use a liquid-cooled engine, and put the
radiator somewhere out in the breeze.

Yes, you could. It would then be fine at values around this voltage and
current but arcing would get worse at other levels (which may not matter
if all you use it for is a FullOn/FullOff generator.

As others have mentioned, there are some like the Ecycle. You could also
replace the rotor of an alternator with a PM rotor to raise efficiency.

Again, I'm not sure you understand. All I'm saying is that the motor and
ICE are mounted with their shafts lined up end-to-end. There is a
centrifugal clutch between the motor and ICE. There is no extra belt.
Your sketch shows the car being over 4 feet wide where the motor is.
That's plenty to have the motor, ICE, and bearings for the trailing arm
for the rear wheel all in line.

Can't find power curves at the ecycle site - they state "motor/generator is
greater than 96% efficient under some circumstances". The motors from Perm
Motor (http://www.perm-motor.de/index_e.html) show power curves - their
synchronous motors appear to be the same as their generators, so might be used
either way. These are probably too pricey, but at least their PMG-132 is
cheaper than a similar LEM-200 from Lynch (still more than twice the price of
an Etek).

Run a ICE's output via electric clutch through a dual-shaft bldc or AC motor
directly connected to a motorcycle shaft-drive. Use another, smaller
alternator/bldc at the ICE to charge the pack whether or not driving the wheels
(i.e. lower speeds); if you only engage the clutch at freeway speeds, you
shouldn't need a standard transmission. Most conversions with trannys work on 2
gears, so, for this setup, the drive motor handles low speeds (and perhaps
"power boost" added with the generator/motor when you floor it at high speeds)
and the ICE handles 45mph or above, unless you manually over-ride to keep it
pure EV.
I post this idea every time a ground-up hybrid is discussed, did it even before
Toyota released the first Prius, and haven't seen any argument against it, but
I'm about as far from an engineer as it gets - everything I've learned about
EVs came from this list!

I feel for you, Lee. I keep getting myself into trouble the same way: I

I gotcha the first time. I like your point: who will we allow to make
the decision for us? Will we trust the very people who have
demonstrated their opposition to our goals? Or will we trust ourselves?
While one argument certainly could include "Emergency personnel are
trained to recognize orange wiring," there are counter-arguments. For
instance, I talked to my local firefighters, at two different stations;
neither group had any idea how to recognize high-voltage wiring. They
wouldn't even admit to knowing how to recognize "dangerous" wiring.
Besides, all we'd have to do is retrain them.
In the end, really, I think your sig sums it up:

The fact is that "The Powers That Be" aren't the only ones afraid of
that principle. We're afraid of it ourselves. We don't really want the
responsibility of changing the world.
I refuse to let an arbitrary decision by people who didn't have my best
interests in mind constitute my entire decision on anything, let alone
the wiring color in my EV. I'll make a thoughtful, committed decision
instead.
Orange sounds good for positive, with orange-and-black for negative.
I'm sure I've got appropriately colored electrical tape around here
somewhere...

One slight snag for a direct-drive EV, is that once the ICE is
engaged, it tends to stay engaged while the shaft speed is still above
the clutch engage speed - i.e. if you cut the engine and want to
revert to electric only mode, you have to slow right down to "release"
the engine.. Not a fundamental problem but annoying. An additional
"overrunning clutch" would solve that problem.

Hello Mike,
You can hear the different motor RPM sounds and transmission speeds when
shifting. It may depend on what transmission you have too. My transmission
and axle gears ratio are very low, because I have a EV that weighs over 6000
lbs.
My first gear of 3.5:1 and axle of 5.57:1 has a overall ratio more than
19.495:1 would allow me to go 30 mph's in 1st gear with 32 inch diameter tires.
It is too wicked to leave it in 1st gear to 30, so I normally shift right to
final gear which is 1.0:1.
Most of the time I just leave it in final gear of 1.0:1 which is a 5.57:1
overall ratio to do my driving. My EV has the same acceleration as if when the
350 cu.in. engine was in it.
Other things you could add to the list is:
Main contactor, 400 to 600 amp with coil control by the
controller and/or relay ignition switch.
Two Safety contactors, install on the neg. and pos.
battery lines, control by a relay
control by the ignition switch.
Note: these also isolated controller and motor
while you are charging the batteries.
If you like to have indications on everything that is going on in all the
circuits, which may inform you what or is not what is happening, then you could
add:
AC volt and amp meter for the battery charger AC input's
DC volt and amp meter for the battery charger DC output
Motor Volt and Amp meter- after the controller.
Battery Volt and Amp meter - normally the Emeter.
DC-DC converter Volt and Amp meter.
DC-AC inverter Volt and Amp meter.
Array of display indications in LED's and actual readout forms that light up
with any circuit is on.
Backup control switches, that is used, when a circuit fails, you can bypass
that circuit, while your EV is still moving.
I had perform this only several times, as where a 4 amp fuse blows which are in
blown fuse indicators which tells me what fuse blows and I than switch that
circuit out and install a new circuit, with a array of console switches.
In your list, you should add a very good Main Battery fuse that is a buss bar
bolt in type, Limitron High interrupting type, or 400 to 600 amp rating, which
will take over 1000 of amps for about a minute or up to 200,000 amps for about
a second. My fuse is a Bussman 400 amp Limitron type which is still working
for over 25 years. Today they make a semi-conductor type you could used.
You could also replace all the above indications with a CRT display with lots
of IEEE interfaces. You get only one display of a time, unless you could
install a large CRT that goes across the whole dash and get all the reads out
at the same time.
Another thing you need, is a motor adapter coupler that connects the motor to
the transmission input shaft, directly or thru a flywheel clutch system.
Sometimes the companies that make a motor adapter plate for connection to a
transmission bell housing, supplies this coupler, so it has the correct
spacing.

unlike a gas car , you can be in the wrong gear and not know it right away ,
many times I've been in 3ed and not 1st on a take off and though " humm am I
running out of juice , oh I'm in 3ed " no big deal , shift to 2nd , keep
going . putting it in 1 while going 50 would be bad but not easy , never
done that, .

At highway speeds, shifitng into first can explode the clutch (after
the synchomesh cones hate you). The clutch should explode before you
try to engage the flywheel. This shouldn't harm you, as the pieces
shouldn't escape the bellhousing. If you do engage the flywheel and
motor, they flywheel would rupture. Which can pretty much cut you in
half. You can shift to first in an ICE, like an EV. Generally, it is
pretty difficult to do this, shifting from 4th to 1st instead of 3rd or
5th.
My cousin tried this and exploded the clutch before he managed to do
further harm on a S-10.

Hello Mike,
You can hear the different motor RPM sounds and transmission speeds
when shifting. It may depend on what transmission you have too. My
transmission and axle gears ratio are very low, because I have a EV
that weighs over 6000 lbs.
My first gear of 3.5:1 and axle of 5.57:1 has a overall ratio more
than 19.495:1 would allow me to go 30 mph's in 1st gear with 32 inch
diameter tires. It is too wicked to leave it in 1st gear to 30, so I
normally shift right to final gear which is 1.0:1.
Most of the time I just leave it in final gear of 1.0:1 which is a
5.57:1 overall ratio to do my driving. My EV has the same
acceleration as if when the 350 cu.in. engine was in it.
Other things you could add to the list is:
Main contactor, 400 to 600 amp with coil control by the
controller and/or relay ignition switch.
Two Safety contactors, install on the neg. and pos.
battery lines, control by a relay
control by the ignition switch.
Note: these also isolated controller and motor
while you are charging the batteries.
If you like to have indications on everything that is going on in all
the circuits, which may inform you what or is not what is happening,
then you could add:
AC volt and amp meter for the battery charger AC input's
DC volt and amp meter for the battery charger DC output
Motor Volt and Amp meter- after the controller.

Damon??? you've already seen it?
I doubt that...
Unless you haunt the dark business parks of Kingston Washington.
So OK it 640 amp hours at 36 volts it's a Exide Work Hog Fork Truck battery.
And at first charge looked to have less than 300 watt hours in it. It should
have 23,040 watt hours ...
Rehabbing the dead... I have it up to 1600 watt hours now.
John is on the way for a Eco fest , and it's pouring up here. Sigh....

Has anyone had a chance to test the "new & improved" power cheqs?
http://www.powerdesigners.com/powercheq.htm
Besides balancing while charging or under power, they do it while
sitting idle.
I'm hoping this will reduce the problem of imbalance from unequal
self-discharge. Cars left unplugged for long periods, then charged up
once and driven can have batteries damaged. (If they don't have a Lee
Hart Bat Bridge or equivalent.)
But will individual cells still get out of whack despite the
inter-battery charge shunting? IE do we really just have to keep
periodically (over) charging a parked car?

Most EVs use two (or more) gears because the highway speed gear doesn't
have enough torque for starting/hills, and you can't do highway speeds in
the start/hill gear without the motor going into self-disassembly mode.
It doesn't matter whether the motor is driving or idling when you exceed
it's safe RPMs, the results are the same.
So, unless your motor has enough torque to start in the same gear it can
survive highway speeds in, you'll still need two gears.

Greetings,
I'm Kevin, and the latest newbie to your list, and have recently become
enamored with the idea of converting to an Electric vehicle. I work for a
small company in Deming, WA that manufactures hydro electric power units, so I
will even be charging the vehicle off of hydroelectric power for the most part.
I'm a classic car buff, and have always avoided newer vehicles, and so Im
hoping to modernize an old van I have that I have driven for many years.
My target Vehicle is a '66 Dodge A-100, With a curb weight of approx. 3200
pounds with a V-8 motor. (3 spd. man trans) I am hoping to create a cruising
range of 50 miles, to allow me to commute to work, and look forward to learning
from everyone on this list.

I am falling in love with this EV.Dead on arrival from the auction its
battery pack only had 400+ miles on it.Thanks to Rich grayman Rudman we are
getting
35 miles per charge.He loaned me an avcon.I have over 400 miles on it myself
with the ac on. Dennis Berube
