David Brandt put some of my EV-related stories, poems, and filksongs on
his website at http://www.100megsfree.com/davidbr13/evgems/evgems.htm
however, the link seems to be dead now. "Filksongs" are well-known songs
but with new lyrics.

Hi Chris and welcome to the EVDL. This the place for EV info.
First, you may want to take a look at the hundreds of EVs already
converted/constructed including component and performance specs-
http://www.evalbum.com
You can get a good start on learning about motors and controllers here-
http://www.4qd.co.uk/faq/index.html
For your range and speed requirements, you may be able to get away with a
low voltage (less expensive) conversion-
http://www.austinev.org/evalbum/564.html
Parts used in that conversion-
Motor-
http://cloudelectric.com/item.jhtml?UCIDs=866086%7C1320716&PRID=793424
Controller-
http://cloudelectric.com/item.jhtml?UCIDs=866086%7C1321276&PRID=1350592
And seven off-the-shelf 12V battery chargers, a VERY economical solution for
charging, though the most popular and flexible EV charger is the PFC line by
Manzanita Micro-
http://manzanitamicro.com/chargers3.htm
I strongly suggest you start with lead-acid batteries, much cheaper and
easier than NiMh.

I was thinking about a citicar but most dont work and are expensive if they
remotely work :-( plus they look cool.
I cant afford to convert a normal car. If I had 10 thousand dollars I would
not be worried about it.
so I want to custom build something. I'm figuring build something "around"
a motorcycle chassis. full enclosed with side rigger wheels to make it
stable and all weather.
so now I have some questions of which I can not answer and can not even
find the "resources" to allow me to try and answer. someone pointed me to
this list :-)
one idea was to use D Nimh cells. I can get them for $5 a pop and they are
10amps each !! (10,000mah) maybe cheaper in bulk.
I only need a 30mile range (figure double what I need in reality to have a
buffer)
I can probably figure out most of it but 2 things. what kind of
motor/controller do I need and how in the heck do I "charge" such a thing.?
not sure how much the vehicle will weigh I figure same as it did as a
motorcycle since I will be dropping the engine but then adding batteries
and all weather shell and extensions etc.. plus my 350 pounds. so I figure
500-550 pounds ?? lets figure 700 pounds top end all up road weight unless
I need more batteries and they end up weighing more.
if I ever get enough money converting my VW Thing to EV would be neat but
only if I could get at least a 200 mile range from it so thats not likely
to be for a while and not untill I am quite a bit better off financially
:-)
Suggestions ?

I have a question about the Solectria Charger BC3300.
The marking on the Solectria Force says 220VAC only
but the charging cable has an adapter for 110VAC. My
question is if it is a universal input, does it hurt
(shorten the life of) the charger or the batteries to
use 110VAC for charging all the time or is it just
slower. It is easier for me to access 110VAC outside
than it is to find 220VAC.
Thank you,
Rex Allison

Boy I would not do that!!
Flipping back and forth from 180 to 360 is bound to have a fault of miss
fire and break something.
The PFC charger won't care much, but it's about %10 more efficeint at 360
than 150, and you don't need a Buck modle to get full rated Kw if you are
over 350 volts.
The Zilla's eff is not a main concern, you would be hard pressed to measure
the difference in losses from 180 to 360.
I am not sure you can still get the Link 1000 and 2000s. I helped design
them about a decade ago. I have a Link 2000R on a Freedom 25.

Subject: 2 strings and an EMeter
> I am considering running two 180 volt strings in parallel to lower the
voltage of the traction components. But I would like to charge them with a
PFC as one string at twice the voltage. It requires a few extra contactors
but shouldn't be too bad. The charging will be low current, high voltage.
Driving will be higher current but lower voltage. I'll be limiting the motor
voltage to 150-170. I started thinking about this when someone posted that
the Zilla is more efficient when the pack voltage is close to the motor
voltage.

one Emeter to accurately track both charging and discharging? How about a
Link 1000 that can monitor 2 packs? Could I leave it hooked up to the 2
halves of the pack when charging as a single string?

No, this was for real. I was in college and working part-time as a filling
station attendant, back in the days when we actually pumped gasoline for the
customers. This guy was a regular, had a big Oldsmobile or Buick, but one
day he showed up in this Honda 600. I was amazed that he fit into it, but
he did.
Twenty years ago, Honda 600s and early Civics were not uncommon conversion
gliders. They were wonderfully light and fairly sturdy. I remember seeing,
around 1988, pictures of a 600 with 12(!) golf car batteries in the back,
and it didn't look like it was about to collapse from the weight, either. I
heard of another one using eight 12-volt sweeper batteries (5SHPs) for 96
volts.
The Denver Electric Vehicle council built a true hybrid from a Honda 600.
They fitted a fiberglas body to it, as I recall. I saw it in George Gless's
garage several years ago, but I think they've disposed of it since. Bill
Dube' might know what happened to it.

This charger (actually a Brusa NLG412) is not a true universal input
charger. The 120 volt adapter cord should probably be considered an
emergency device.

If cost isn't an object, how about a superconducting homopolar
motor/generator---no commutation, electric or mechanical, just brushes.
>From http://www.ga.com/atg/homo.php# :
The superconducting DC homopolar motor is considered to be a conceptually
superior alternative to the AC motors. Compelling advantages of the
superconducting DC motor include:
1) Significantly quieter, smaller, and lighter than AC motors
2)5% more efficient than the AC motor systems
3)Control is more straightforward and simpler than the AC motor systems
Also, http://www.memagazine.org/backissues/april00/features/hunt/hunt.html
The navy likes electric for compact, quiet propulsion with high efficiency
and high torque at broad speed range.
Now, if we can just get Jim to build John Wayland a lightweight,
superconducting, 1000HP homopolar motor. Oh yeah, I forgot to mention that
these things are very low voltage, very high current machines (e.g.
13000amps at 100v for 1.3MW)---maybe it's not a good idea for drag racing
after all.

This doesn't generally work, unless the difference between the batteries
is so large that it overcomes the natural variations between the
vehicles and how their owners drive them and treat the batteries.
It would be better to use one type of battery for half the pack, and
another type for the other half. You'd need some kind of balancing
system to keep them together as a "team" (can be as simple as two
chargers, one for each half-pack).
Anyway, it will become obvious which type of battery is "weaker" in the
application this way.

I'd say if you perceive the problem, it is up to you to do something
about it. Others either don't notice, don't care, or don't have an
incentive to do anything about it. Waiting, complaining, etc. are
pointless -- you'll be waiting forever. Some dream of a better future;
others get out of bed and make it happen.
If your EV is licensed as a normal car, and can go over the minimum
speed limit (45 mph, I believe), then I think you can legally drive it
on any roads. It might not be safe or even sane -- but it's legal!
So, "souping up" your NEV is a perfectly reasonable desire, so you can
increase its utility. In my darker moments, I suspect that the auto
companies bought the NEV companies and lobbbied the government to be
*sure* that they won't threaten normal cars. But they can clearly go
faster. Watching what the racers do will give you ideas on how it can be
accomplished.
The other thing you can do is make the best of your situation. My daily
commute used to include a 4-mile stretch of freeway. My EV at the time
(a ComutaVan) was basically an NEV but licensed as a normal car -- with
its bigger tires, bigger motor, and more batteries, it could barely
reach 55 mph. During "crush hour", traffic moved slow enough that I
could take that freeway without holding anyonw up (*nobody* was going
over 55 mph).
But other times, when people drove 70 mph, I stayed off. However, I
discovered that there are parallel roads that got me the same places. It
was a bit longer and slower, but a more scenic and relaxing drive. After
a while, I found that I preferred the scenic routes even when I could
take the freeway. And on bad traffic days, my scenic routes were
actually faster!
BTW, David Roden wrote an excellent response on this as it relates to
the EV list!
