Go with GEICO.

They are easy to deal with as far as getting insurance.

They insure the car for what it is. They told me according to them its a Ford Escort whether it was powered by gas or electricity.

Only problem I had was with a claim. My car was broadsided and because the body damage ($1,200) was worth more then the car they said it was totalled. Obviously it doesn't take much more then a dent for an '87 car as totaled. So that was no surprise. But I proved what the going rate was for EVs like mine were (thanks to the EV Trading Post) and they sent me $1200.

Progressive might be another one to try.

I was rejected by one company. At the time we were working with a financial advisor who suggested we put all our stuff under their group of financial and insurance providers. Everything was going well until the issue of the EV came up with their insurance company. They claimed I wasn't "skilled" enough to build an EV even though GEICO was insuring it already. So we rejected them and showed the financial advisor the door.

But GEICO was the easiest and their rates are pretty good too. Even though we had that issue with the accident they worked with us to give us the claim.

I know this has been covered, but I've done a couple searches in the

writing EV insurance other than The Hartford.  Some others people are
insured with?

If I read his email right, he is willing to give his Hairball 2 internal code 
to somebody he TRUSTS to develop it. The hairball already has a place for a 
MAX1660 chip. This chip will accurately monitor a battery pack's charge and 
discharge current flow. 

Does one of our wonder programmers want to rise to the ocassion? I would 
suggest that you contact him off list, and don't be suprised if it takes a week 
or 2 for him to answer, he is pretty busy.

If you don't like the format of the EVDL, setup something else and post
the contact information.  If enough people like the new format, it will
prosper, otherwise it probably won't.  Endless discussions won't change

Thousands of people around the world would disagree with you, they are
using lead-acid quite sucessfully in EVs.

I guess that depends on your definition of "few" and which type of battery
you use.  Most people get over 10,000 miles and a few get over 20,000
miles out of a set of GC batteries.

Well, everyone is entitled to their own opinion.  For the vast majority,
pure electrics (using lead-acid batteries) provide enough range for most
of their daily needs.

Hybrids look good on paper, but most people who try building them end up
with little or no improvement over ordinary cars.

There used to be a university competition here in the states with the goal
of building a hybrid that got double the normal gas mileage.  Most of the
entries couldn't even MATCH the normal gas mileage and I don't think
anyone ever managed to reach to goal of double.

--- Begin Message --- Having worked as a claim adjuster, the best advice I can give is to not hide anything - by omission or otherwise. If the insurance company takes the position that you failed to disclose information relating to the value of the vehicle, then you could have your claim denied entirely, if not merely paid at market value for a non-EV.

Don't take a chance. Make sure they know, and if necessary, get a policy with a stated value.

Series hybrids are the most difficult to make efficient.

The power from your engine most go through conversion to electricicty -
where you will loose approx 10-20% of your power-, then if you are going
to store it in a battery you'll loose another 10-25% of your power, then
you convert it from electricity back to mechanical motion and loose
another 10-20% of your power.

You'd be better off using a smaller engine dircetly coupled to the wheels
and suplementing it's power with an electric motor for acceleration and
hills.  The electric motor could provide regen braking to get a portion of
this acceleration energy back during braking, and then you could add a
small generator to the diesel/etc. to make up for the lost energy.

I'm still interested to know where you have found affordable hub motors
at.  Here in the states I'm only aware of one company that makes hub
motors powerfull enough for a car size EV and they cost something like
~$20,000 each.

Great, go ahead and start a BBS and convert all of the old archieves over
and then invite everyone to join.

Oh, you mean you want someone /else/ to do all the work for you just to

Subject: Electric Vehicle bursts into flames in San Francisco - again!


At first I thought this was a hoax, similar to the stories about hollywood
celebrities whose cars had burst into flames inside their houses.

I still think it's arson.  But whatever the case, it's real:


http://sfgate.com/cgi-bin/article.cgi?f=/c/a/2007/01/26/BAGGONPRBP14.DTL
Fire closes Warming Hut
Electric car outside Crissy Field cafe bursts into flames
(01-26) 13:25 PST -- An electric vehicle parked outside the Warming Hut at
Crissy Field caught fire early this morning, damaging the popular cafe and
gift shop so severely that it will remain closed for several weeks while the
National Park Service makes repairs.

Golden Gate Bridge security officers saw a two-story pillar of flame shortly
after midnight and alerted the Park Service Fire Department, which
extinguished the fire within 30 minutes, said Rich Weideman, a spokesman for
the Golden Gate National Recreation Area.

Investigators determined the blaze started with an electrical fire in a
nearby Gem electric vehicle, but they do not know what went wrong with the
vehicle, Weideman said. The vehicle was unplugged and parked on the west
side of the Warming Hut, he said.

The fire caused relatively little damage, but the smoke it generated and the
water used to extinguish it made a mess of the building and its inventory,
Weideman said.

The Warming Hut is among the park's most popular buildings, a place where
tourists and locals alike grab a cup of coffee, a bite to eat and a
souvenir. With the Warming Hut boarded up, visitors are encouraged to visit
the Crissy Cafe not far away at the Crissy Center.

Today's fire was the second time a Gem vehicle has caught fire at the Golden
Gate National Recreation Area. One of the DaimlerChrysler-made vehicles
caught fire a year ago at Alcatraz Island. That vehicle was plugged in at
the time, prompting GGNRA officials to adopt a policy requiring that
unattended vehicles be left unplugged, Weideman said.

In both cases, the vehicles "burned literally to the frame," and
investigators suspect a problem with the vehicles' batteries or wiring,
Weideman said. Park authorities contacted DaimlerChrysler after last year's
fire and were told the automaker was not aware of any problems, Weideman
said.

Park officials have once again contacted DaimlerChrysler and will be working with the company to determine what went wrong. In the meantime, the park and the Golden Gate National Park Conservancy, the park's nonprofit fundraising and outreach arm, are reviewing their policies regarding the use and storage
of Gem vehicles, Weideman said.

>Are the AC motors special purpose EV built units? Or are they derived from
>industrial units?

Both have been done. EV control typically requires a speed sensor
on the motor for proper control, though. This is fairly easy to
add. The AC motors sold by Metric Mind are purpose-built for EV's,
but as with any technology like that, certainly would have evolved
from an industrial motor.

If you pick the correct rotor type (torque curve), a 15HP motor will be
capable of producing somewhere around 50 to 80HP for a while - but
efficiency drops a bit up there, and you are thermally limited - ie
you can do that until the motor gets too hot. Basically,
for high-torque operation, you run the motor in the 'startup' torque
region, which can be from 2 to 5 times the nominal running torque. This
multiplier depends on the rotor construction, mostly, and the torque vs.
efficiency vs. slip is typically published. Alternately, torque vs. rpm
and efficiency vs. rpm can be used given that the typical 1800 RPM speed
(in North America) is zero-slip. In Europe, 1500 RPM is your number.

In 'Motor Control Electronics Handbook', Richard Valentine and a few others
did a couple of conversions of a 1993 Dodge Dakota. One conversion tried
was an FB-4001 Advanced DC, and the other used a 15kW (20 HP) size 256
frame motor rewound from 230V to 150V. They added a speed sensor, and
built a 400A VFD for it. This motor was capable of running at close to
100kW without problems. They were using a 288V battery pack, which is
about right for a 150 to 180V RMS output.

It's not that 'complicated' but getting good reliability from power
stages does take a lot of engineering. Something that switches 400 volts
and 400 amps, at 10,000 or 20,000 Hz is something of a challenge,
actually. The various units sold by Metric Mind appear to be quite
nice - and automotive-designed. I have not used them myself, although
I would like to try them someday. If you are an electronics
designer by trade (as I am), I think you could learn to build a VFD
but I am pretty convinced that, for one or two drives, it would be
cheaper to buy them. In my power electronics experience, someone
designing one of these drives will probably blow up one or two sets
of IGBT's, and at that power level, one explosion (which will usually
take out all six IGBT's - and many parts on the driver board)
costs somewhere around $500. It's also loud, so wear hearing
protection when you crank it up.

Typically either a vector control or a slip-control algorithm will
be used, not an open-loop V/F as would be sufficient on a single-
speed device, which many industrial non-servo applications would
need. You also don't want a PID controller on motor speed. This
is quite difficult to drive - it's like fighting a cruise control
constantly, when you don't want it. The programming of some industrial
drives may allow this, but most I would expect would be set up
for either constant frequency output (open-loop), or closed-loop
speed regulation. You want neither of those for a vehicle.

>The only draw back I can see is the high voltage needed to drive the motors

AC
>inductance motor?

Lower full-torque speed, lower power, slightly lower efficiency (because the
inherent voltage drops in IGBT's start to get more significant as the
voltages
are dropped.

Right now, using high voltage affects the battery cost, although
when you get above 13 or 14 12-volt batteries, you're in the right ballpark
for voltage. Battery balancing is a bit more of an issue just because you
have more batteries. Also, AC drives are somewhat more expensive than a
similar DC drive (at least, for a hobbyist) at this time. For an OEM, this
situation is likely reversed. The difference in cost vs. advantages of
AC would likely swing them into using an AC system, just as some
hobbyists do.

Despite the cost hit that an AC system provides, quite a few hobbyists have
built vehicles using various AC systems. The Metric Mind Siemens system
has been used quite a bit. If you search through the evalbum you'll see
various AC and BLDC systems in use - a BLDC (brushless DC) motor is more
related to an AC induction motor than it is to its brushed cousin - at least
in terms of electronics.

Hello from Edinburgh Simon !

A few months ago before I sourced a nice DC motor I did some writing 
to various companies. There a lot of companies in the UK which make 
AC motors, but not many of them are  interested in DC. 
www.brookcrompton.com have a comprehensive range of AC motors and 
some drives, but I didn't research drives very much.

I'm working on refitting a 1995 Clio with an old milkfloat motor, an 
SCR controller made from a hacked forklift SCR based speed  
controller, and flooded lead acid cells.

Best Regards
Chris

That EV may have not have any safety contactors to isolated the charging 
voltage from the main contactor, controller and motor.

Also was batteries double insulated from the frame of the EV that is AC 
ground?

Was there a on board GFCI and best to have a ground detecting systems that 
measures any voltage leaking from the batteries to the any grounded 
enclosure or frame that shuts off a the incoming AC power by use of a AC 
magnetic enclose contactor. This ground detection system is normally use in 
a higher voltage and ampere in industrial applications which can shut down a 
pad mount transformer.

Is there a battery enclosure explosive proof ventilation system to exhaust 
any fumes that is also prevents the cross ventilation of a battery charger?

Is there a interlock between the battery exhaust systems and charging 
systems, as where the exhaust units comes on first to purge any fumes, than 
20 seconds later, it turns on the AC power by means of a AC contactor.

Is all the batteries manufacture date the same date?  I had 10 batteries 
that were 10 months older that got slip into my new pack of 30, which blew 
there tops the minute I press the accelerator.

Was there a BMS system use to prevent over or under charging?

If you are not using any of the above, as I do, I will be scare to turn on 
the charger, as any of the above has blown up a EV or burn out components.

To test out to see how safe you EV is.  Charge the batteries, with the 
lights off or in the dark, and see if there is any small arcs from any of 
the battery cases to a metal frame.

I had aluminum battery boxes at one time, and I had many arc over which you 
cannot see in the light but only when its dark.

I fear one defective GEM will bring in stupid people to make stupid
decisions affecting all EVs (like unplugging unattended EVs).

I hope the SF EAA Chapter is contacted and is working on this to
keep intelligent, knowledgeable EV drivers involved with any
decision making.

I also hope this incident is clarified with the media that it is a
GEM issue, not all EVs burst into flames.

Jerry,
   Sorry to hear about the unfortunate events. I've been sitting  around with 
a herring on my tongue (baited breath) waiting to see what a  finished 
Freedom looks like. I will be looking forward to seeing its performance  even 
if the 
paint job is a little tacky.
   Somebody take lots of pictures at BBB.
 
Yours,
 
Pat

Sushrut,

It is a personal choice of what battery chemistry one uses.

I have been using lead acid since 1992. My EV is my only
transporation, it does what I need it to do.

For me to switch to a higher density battery pack, I would incurr:
-a higher pack cost
-a need for a battery management box/system that is currently not
available off the shelf
-and I would need to ensure my charger will charge that pack
correctly without damaging it

The above points are a major hurdle for many people who have
realized that a lead-acid pack does 90% or more of their driving
needs.

Certainly a more reasonable position than what others seem to be taking,
but not quite fair, nonetheless.

It is not at all clear that this is a GEM issue, and it is certainly not
the case that GEMs are the only EVs that burst into flames (it wasn't
that long ago that a California EVDL member's 914 loaded with Optima YTs
burst into flames despite also not being plugged in at the time).

Bear in mind that GEMs are likely the most numerous on-road EVs at
present (I've heard numbers of like 8-10k or more GEM vehicles in the
field), so even if they are no more likely to burst into flames than any
other EV, odds are that we will hear of more GEMs doing so than any
other simply because of their greater numbers.

Cheers,

Roger.

OK, gotta jump in to this one...

Re: whether it's useful to tell GM that we want to buy the Volt...I guess my question would be, why wouldn't you? Even if you believe GM will never build it, it is crucial that we as consumers continue to demonstrate demand. If you don't, and GM doesn't build this car, you've handed them a reason why. If you do, and they still don't build it, it calls them out- let's face it, demand for the EV1 would have been a lot harder to prove without the 5,000 person waiting list. The truth is that there is and always was demand for plug-in cars- but we've nothing to gain by not getting that truth out there at every opportinity.

I'm not at all naive in this, of course, especially when it comes to GM- what happened with the EV1 is as personal to me as anyone. But being encouraged by the Volt announcement is not the same as letting them off the hook for EV1- indeed, many of the people whom I feel did the most damage to the EV1 program are no longer there anyhow, and I personally think it's more productive at this point to move forward than look back. Bob and I were in Detroit with Chris Paine for the Volt announcement, and between that and other meetings, I've have had many hours of recent conversation with both the Volt designers and engineers as well as the execs and PR folks. A lot can happen between concept car and showroom, and ultimately, I'm going to judge them on what they do, not what they say. But all pr spin aside, there is a level of commitment and sincerity in the individuals involved that I've not seen in years- and I know for certain that we've collectively played a part in the fact that they're even pursuing this direction again; not only do I hope they follow through, I think it's crucial for the future of the company. Do I wish they'd never taken the detour? Of course...but this is exactly what we've been working for, and if we can't allow the slightest optimism, I have to wonder why we're bothering?

The reality is that not one of the car companies behaved honorably with respect to their EV programs. But I also believe that while they each have a lot of ground to make up, none of them are beyond redemption. To the extent that any of them are wanting to take a step in a better direction, I think it's important to allow them to take it (or not) before we judge.

from the EV community? I would go for an interest free type loan, if it
could come to that? How many guyz, an' gals on the List? Over a thou?
EVerybody kicked in two bux a month? Or; (gasp!) 5 or 10?? Still less than

And they will! "Stay the course" as our Dear Leader sez! And how many Sheeple say; " Geees! I NEVER knew all this actually happened", after seeing
WKtEC, and" I lent out your DVD to the guyz at work" Why I rarely "see" my
copies of WKtEV!

> >>Hi EVerybody;Again

    Volt? Yeah Right?Phooey! GM HAD the EV-1 which was better by far than
the Volt. If they HAD to do a @#$%^  Hybrid, use the EV-1, tuck a gas, or
Diseasel engine aboard, EVen a rear bumper clamp-on, taken along as needed.
You pick it up at the Charge Station on the way to Aunt Tilly's in Toledo.
"Charge Station?"Yup! I think they would spring up along the interstates,
like with GM's help, IF they were serious about EV's? EVen our crappy home
made cars , conversions, would be of full usefullness, if we could dump
aboard several hundred amps during coffee or piss breaks?Thought for the
day; How good , convenient, would your GAS car be if there were no gas
stations?IF ya had to buy gas in one liter cans at a drug store??

Well, with GM sitting on the nmh patents it wouldn't take much for them
to use Stan Ovshinski's batteries? Sheesh! GM was sitting on top of the
World, a few years ago, and they threw it away!Shame on them! Gunna need a
real Regime Change at GM to get anything becides the reVOLTing thing. Smoke
and mirrers. Sigh! But I voted early and often as they used to say.

Westfield.  I've never had a problem.  

Well, almost.  When I first called up with the Comuta-Car, my agent said, 
"It's a WHAT?  I'll have to call you back."  But she did call back, a day 
later, after talking to the head office, and she wrote the policy.
