Why does it have to be political??? EPA specs based on hot air don't help
anyone, except the car salesmen.
If specs says 60MPG, the average "light footed" driver, in the average
model, should be able to do so, at *some* speed... instead of the average
car getting 15-40% worse-than-sticker.

Chargers that only handle a few cells in series.
When you have 200+ cells in series, that don't ALL hit the knee at the
same time, it might get a bit obscured. I.e how do you see one cell knee
over when 199+ other cells are still climbing?
Perhaps I'm wrong about this. Has anyone tried it yet (looking for the
knee on a 300V+ nicad pack)?

Or perhaps a transfer case from a 4WD, these are usually designed to have
two separate ratios with a lever/button/etc. to select speed. They are
also designed to run continously at fairly high power levels.
The only disadvantage is that usually one ratio is 1:1 and the other is
typically around 2:1

Umm, at only 3,000 watts, that 914 isn't going to be "running"...walking or
jogging maybe.
I'm guessing that 3,000 watts is good for about 10-15 mph.

In years past, I've had good results using USBMC batteries with Lester
Lestronic II chargers. And in fact what Lesters do sounds pretty close to
USBMC's specs : dv/dt algorithm, bulk charge at around 25 amps, finish at 5
to 8 amps (depending on model). I wonder if this bog-standard golf car
charger might indeed have been in the battery's designers' minds.

I finally decided I have to try playing with a contactor controller, so I
bought some surpluss contactors off ebay to give a whirl. The theory is
simple enough and has been discussed on this list plenty of times, but some
of the practical aspects I am wondering about include what people have used
to control the switching itself. Generally you are using some kind of
mechanical device such as a cable or throttle linkage as a control device.
What are some good ways to turn this motion into an action which causes the
coils of the appropriate contactors to be energized and what kind of
failsafe measures are used to be sure that two contactors that shouldn't be
engaged at the same time never are.
I may never do anything but change the voltage across a light bulb with this
just to see it work, but with an ev scooter, an ev motorcycle, and likely an
ev truck in the near future I am developing a natural progression of
platforms to test new(100 year old) ideas on :-)

Damon,
In a road-going EV it can be helpful to have a backup controller,
in case your electronic controller fails, also dependent on the
record of the controller itself - if it's self-built it may be
even more desirable than when having a known-to-fail-someday
industrial controller.
Since about half the contactors are already needed in a
road-going EV, why not put two more in to make a CC for the
moments you need it to move out of the way/get home?
Essentially the same reason why many cars carry a spare tire.

Well, there is the tried-and-true drum controller as used (perfected?)
in turn of the century electrics.
A more modern approach might use a CMOS 1-of-N decoder to provide a
hardware means of ensuring that multiple relays cannot be energised
simultaneously, and either a mechanical or electronic means of
generating the control signal(s) to the decoder(s). This is one of the
sorts of hardware safety built into Lee's Balancer to ensure that even
if the software loses its mind it still can't pull in multiple relays.
If you really want to bring the contactor controller into the 21st
century, a small micro that accepts a 0-5K (for instance) throttle
command and monitors motor current, voltage and/or speed could generate
the contactor control signals (fed through the 1-of-N decoder for
safety) and guard against such user 'errors' as mashing the pedal at a
stop, and/or enforce some maximum current limit (e.g. mashing the
throttle could result in a controlled progression through the various
control speed steps, either advancing to the next higher speed only when
the motor current falls below a limit such that the next step won't
over-current the motor, or advancing simply based on spending a minimum
amount of time in each step on the way up, etc.).
Cheers,
Roger.

Unfortuantely while it may lower rear end accidents to motorcycles ( if
that is true and I doubt it) it makes driving for car driver and much
more harrowing task.
It is akin to having people demand to right to walk in crowds with
pitbulls or razor edged swords.
they can say it is no dnager if others simply don't bump them. However
is that really reasonable?
Those who create a dangerous situation are just as liable as the person
who bumps it.
Doing a normal mirror scan there is a time point when you cannot be
looking at all sides of the lanes. And at some point you make the
decision to move to another lane or to shift to one side of your lane to
see around the suv in front of you ( another sore point) . A motorcycle
often speeds in between lanes at those times.
Now if I happen to shift to the right side of the lane after looking and
while my scan was left and a motorcycle was knocked over while spiltting
lanes and his foot was crushed by someones tire whose fault do you think
that should be?
And even if the car driver was judged not at fault who compensate him
for time lost from work defending himself in court from the inevitable
lawsuit?
Motorcycles simply split lanes because they are impatient. There is no
excuse ofr playing such a dangerous game and pretty everyone else on
edge and at risk for an accident.
It is simply unreasonable to expect others to "deal with it".

That is a common misconception held by the majority of automobile
drivers.
Actually the data shows that motorcyclists are much safer splitting
lanes
than sitting in traffic. Rear end collisions where motorcyclists are
killed
are far lower (30-50%) in California than other states with similar
riding
seasons. Conversely the number of fatal accidents where motorcycles are
hit
from the side or front is statistically the same as most other states
for
each mile driven. This means that insurance rates should be LOWER for
California. Unfortunately non-fatal accidents do not have the data
resolution of fatal accidents, which is why these numbers stem from
fatalities.
If you would like to delve deeper into the data, you can use FARS
(http://www-fars.nhtsa.dot.gov/) or read the Hurt Report
(http://www.clarity.net/~adam/hurt-report.html), the last available
comprehensive motorcycle fatality analysis.
There are two things that you can do to ensure you will never hit a
motorcycle splitting lanes. Use your turn signal and check your
mirrors. A
blinking signal for motorcyclists is like garlic to a vampire. We take
notice.
It is unfortunate that a minority of motorcyclists do not abide by the
laws
and give all bikers a bad name. Trust me, as a motorcyclist I have to
put up
with auto drivers AND these poorly skilled motorcyclists trying to kill
me.
Two inches may seem like nothing for a big heavy car, but for a skinny
nimble motorcycle it is a gaping hole.

Subject: Re: Tango lane splitting
Frankly I see motorcycles lane split in la all the time. They are not
lane sharing.
It is unfortunately and burden on others and a hazard.
It also rasies insuranc erates and lawsuits as riders who take a
dangerous lane split inevitably sue the poor auto driver who doesn't
see
them passing from behind with two inches to spare and unknowingly close
the gap and are invovled in an accident.
Sorry but I am for a separate lane but lane sharing is ridiculous and
dangerous.

Lane splitting is illegal in all 50 states, so Tango cannot "split"
lanes, ie. straddle the lane boundry, anywhere in the US, just like
motorcycles. You will be cited for unsafe lane change or straddling if
the cop can catch you. It should be able to lane share, but only if it
stays within one lane, and only changes lanes every 100ft, just like a
motorcycle. For more than 7 years, every day, rain or shine, I split
and share lanes and can tell you with two wheels I can stay legal
about
80-90% of the time. With 4 wheels it would be nearly impossible not to
straddle. Motorcycles are allowed to drive abreast in 42 states, but
only California has no law prohibiting motorcycles to share a lane
with
a car. I am a big proponent of lanesharing and the positive effect on
reducing congestion, but from what I have seen of the width I would
not
share lanes in the Tango. But I would love to watch one try. Just keep
an eye on your six and let faster splitters go by.
Take a look what motorcyclist have to say about this very topic:

I wonder if it is really legal for Tangos to drive two abreast?
I got this answer from Rick Woodbury of Commuter Cars Inc.
According to testimony given at a Senate Transportation Committee
Hearing in WA state by a captain of the WA State Patrol, it is legal
for
2 Tango to share a lane, but not overtake in a lane.
In CA all 30 traffic officers who were asked, mostly CHP, unanimously
stated that they would not ticket Tangos for lane splitting. Lane
sharing is certainly not a problem.

No, C/20. Nawaz said:

C/10 would be 22A.

Considering the cost of a charger capable of >25A at pack voltage,
and the nominal savings you get as a result of buying USB's, even
in the event of all other things being equal (cycle life, range,
etc) then I had to go with the obvious choice, as you point out.
Any prospective Trojan replacement would have to be just like a
Trojan but only one half to two thirds the price to justify
replacing the charger.

Well, I tried that with a few friends - they still are friends, because they
know how much I love EVs, but they had very good reasons NOT to buy them.
Indeed, maintenance and price difference were a few, but it had different
characteristics as well.
Not feeling comfortable driving an EV (since they cannot just go out and buy
one and get the experience) so even test driving an EV is a problem. Then
the limit of range and if you don't have a second car, that can get
uncomfortable or embarrassing (can you pick me up? Uhhh - no, not today.
Tomorrow maybe or if you don't mind that it will be late, after I recharged)
My first car in the US was a Hybrid. At least half an EV, better than
nothing and it had the range and price that did fit my bill.
I agree that the beefed-up-starter types are not worthy of the Hybrid name,
but in the name of marketing and seeing that this improves the fuel economy
without raising cost price, it makes less committed car manufacturers
willing to take a first baby step towards electrifying the drive train, the
ultimate goal.

I'l just say for the record I am not blind.
The problem I had came from the fact that without realizing it we all
use auditory cues to alert us to the proximity of vehicles often in
order to turn our head to look or to realize we need to move.
We will all need to be more alert as pedestrians but it would be bad if
someone got hit in the meantime.
It also doesn't help if owners are "having fun creeping up on people".
NOT a good idea.

National Blind Foundation. They emailed several of us from EVA/DC and
www.GlobalBoiling.com for daily images about hurricanes, globalwarming
and the melting poles.

Sorry for being sarcastic. I'm very skeptical of companies with "new

Sure, which version?
When you know what you want (which voltages) and how many speeds
(with start resistors) then the only practical thing is if you
have single pole contactors or multi-pole and whether you want to build with
diodes or all contactors
(three voltage levels can require up to 9 contactors)
Some safety-additions to avoid short circuses by checking contactor state
require some helper contacts to make things a even little more complicated,
but the essential ingredient of any contactor controller is:
- one "series" contactor that can switch two (sets of) batteries in series
(connect one + to next -)
- two "parallel" contactors (or two contacts on a single contactor) to
switch two (sets of) batteries in parallel (connect one + to the other + and
one - to the next -)
The rest is variations on this, adding second or third layers of
series/parallel switching and adding a startup resistor that can be bypassed
by a contactor.
Hope this helps,

Do you have schematics for CCs?

They say *nothing* about the technology save for that it is "better"
There isn't any information about which patents they supposedly hold,
either. You can apply to test their motors if you are a motor manufacturer.
I only know one motor manufacturer and he's probably not interested.

The US2200 has traditionally been rated 225Ah, but the latest "XC"

I'm sure it depends on the relative costs of the batteries in your area
and what sort of charger(s) you are looking at, etc. A decent charger
is an investment, but if you have already invested in a charger that is
inadequate for certain batteries and cannot modify it economically or
resell it to offset the cost of a better or more versatile charger, then
the most cost effective option may be to only use batteries that are
compatible with what you already have.
Traditionally there have been multiple factors encouraging people to use
US batteries vs Trojan, including lower cost and availability of the
batteries with EV-appropriate terminals. If you decide to go with
Trojan for your next pack, be sure to confirm that your dealer will
supply them with an appropriate post, and that you aren't going to be
hit with some surcharge for demanding something other than the now
standard low-profile post use by golf car applications (the SAE portion
is too short for a standard battery clamp, leaving just the threaded
stud to connect to).
Cheers,
Roger.

If you are interested, you can go to <http://www.uspto.gov> and search
the patents/applications for the keyword "Raser":
Some relevant application hits:

The emotional response people have to lane splitting interests me. My wife
feels the same way, and I struggle to understand why. I think it's a response
to being startled. Ironically, if lane splitting were more common don't think
it would arouse the kinds of negative responses it does now, because people
wouldn't be surprised by having a motorcycle slip by, whereas now it's a
combination of a fast, noisy object suddenly appearing where you don't expect
it - and a certain amount of jealousy caused by the fact that you're stuck
there in traffic and they're not.
Seriously - lane splitting isn't going to cause the downfall of Life As We Know
It. Relax, remember that that motorcycle splitting lanes isn't going to make
you get there any slower (maybe faster, since it's not taking up a spot in the
lane) and think about something happy - like converting one to bat-power!
But I don't think you could do it in a Tango.

It is akin to having people demand to right to walk in crowds with
pitbulls or razor edged swords.
they can say it is no dnager if others simply don't bump them. However
is that really reasonable?
Those who create a dangerous situation are just as liable as the person
who bumps it.
Doing a normal mirror scan there is a time point when you cannot be
looking at all sides of the lanes. And at some point you make the
decision to move to another lane or to shift to one side of your lane to
see around the suv in front of you ( another sore point) . A motorcycle
often speeds in between lanes at those times.
Now if I happen to shift to the right side of the lane after looking and
while my scan was left and a motorcycle was knocked over while spiltting
lanes and his foot was crushed by someones tire whose fault do you think
that should be?
And even if the car driver was judged not at fault who compensate him
for time lost from work defending himself in court from the inevitable
lawsuit?
Motorcycles simply split lanes because they are impatient. There is no
excuse ofr playing such a dangerous game and pretty everyone else on
edge and at risk for an accident.
It is simply unreasonable to expect others to "deal with it".
