The Motorcycle Riders Foundation has the most current
information that I have seen and they have written the
law down for the layman.
http://www.mrf.org/pp-epa-for-the-layman.php  As it
stands, one emission exempt bike in YOUR LIFETIME.  As
in, you cant sell the one you got and then buy a
different one.  For me, a guy who believes in personal
freedom and the right to change your mind if you want,
this is a personal affront to life, liberty, and the
pursuit of happiness (or is it property).  I bet many
on this list would be upset if they were told that
each person is only authorized one EV in their
lifetime (or did I mean EV1).  

Yeah, Dale, I would be interested in seeing an
electric custom chopper done by Jesse, but considering
the ribbing that some of the members here got when
they were on the Monster Garage Show, I dont think
that it is his thing.  There is an electric custom
chopper by Big Bear. 
http://electricmotorcycles.net/modules/wordpress/?p=34

http://www.bigbearchoppers.com/gallery/bbc_builds.htm#
I am also looking forward to an accomplished artist by
the name of COOP to do one in his blog.

G'day All

Don in South Australia is building an EV on a tight budget. He has a 24 to 48 volt EV1 controller, but 48 volts is likely to be a bit on the low side for his beetle.

I know that control boards in higher voltages are available, so first question:
Have any of you access to a higher voltage EV1 control board that Don could have/buy cheaply? If so, that'd sort the controller voltage issue.

OK, next question, can anyone provide me a schematic of an EV1, preferably the PCB schematic, and I'll see if I can modify Dons' controller to higher voltage, OR if possible run the control PCB from a DC/DC converter whilst the SCRs run from a higher voltage?

Last option, does anyone know how much difference is there between the EV1 models? I have a 1H9 oscillator card, Dons' is a 1H3. What are the odds that I'd be able to modify Dons' oscillator card to be the same as mine to let him go as high as 84V?

Thanks in advance

Regards

[Technik] James

Subject: Jessie James should build electric motorcycles

Just saw Jessie James of West Coast Choppers was fined $275,000 by the
CARB for violating emission regulations on his customer's motorcycles.
It was like 50 custom bikes he made that were in violation. Ouch.

Think of the electric motorcycles you could build for $275,000.

Chris,

That is around the corner from here!

No. There was one being sold by an EV club out there. Proceeds to go to the EV club, posted to a bunch of EV lists..

It wasn't ended early, it was canceled with a message to all bidders saying that the seller has been suspended and if you get an offer to buy the item to contact the cops. Which was pretty heavy-handed I think.

I've actually been apprehensive about cleaning my batteries because
I don't know how to do it safely.

On my cars with floodeds, I clean them as follows.

1. Pull the fuses or disconnects, so they are isolated. My EVs have
   broken them up into units of 36v or less, so there's no shock hazard.

2. Put some detergent and baking soda in water, and use this to scrub
   the tops with a plastic scrub brush. Wear rubber gloves and old
   clothes*.

3. Rinse 'em off with a garden hose, to get rid of the soap and crud.

4. Smear vaseline on the terminals. This helps reduce corrosion.

That's it! Usually needs to be done every 6 months or so (or more as the batteries get older, because they gas and fizz more).

* Battery acid dissolves cotton. If you touch an acid-wetted battery with your hands, it will have no effect on your hands. But if you wipe them on your cotton jeans or shirt, you'll discover little holes in them the next time you wash them!

Plywood is a poor electrical insulator. It absorbs water, and becomes conductive. It is attacked by battery acid, which carbonizes it to become much more conductive. It also burns!

There are much better alternatives. Coroplast (plastic sign board) is totally nonconductive, non-absorbent, and isn't affected by battery acid -- but it burns. Polyethylene, polypropylene, styrafoam, urethane foam, and other plastics also work, and are available will fire retardant additives. Surplus phenolic or FR4 fiberglass epoxy printed circuit board material is very good.

I'm curious.... why all the plywood seperators? 2 reasons I could think of for 
NOT using them are 

1. wood and acid do not play well together.
2. wood becomes another source of fuel should a fire actually occur.

I don't think you need seperators between the batteries.

Also regarding your cleaning of posts.... after cleaning coat them with axle 
grease or vaseline, this will greatly increase the interval between cleanings. 
Some may suggest using Noalox which is a name brand for a substance used for NO 
ALuminum OXide. Since there shouldn't be any aluminum in your lead terminals it 
would for you just be an expensive form of vaseline or axle grease.

Is the link to the auction not in your "Items I'm Bidding On" list. 

In case you are not aware of such a list.... it is under "My Ebay".

Is that directly from UPG?  That seems really cheap.

  Initially I thought an 8D would have greater energy
density per pound than two 6 volts due to tighter
packaging and less case material, but the opposite
seems to be true.  Why is this, more robust
construction in the 8D?
  Do you not consider the fewer connections of an 8D
setup to be advantageous?

How about Rolls?  My father in law swears by them.  He uses them for marine
applications.

Rolls makes very long life, deep cycle lead-acid batteries. However, they are very expensive for the amphour capacity, and have very poor high-current characteristics. They would only be suitable for an EV that had a very large proportion of its weight in batteries so the load current per battery is very low. It would be a very slow heavy vehicle, but you'd have good range and long life.

WOW,
Thanks to Shawn and everyone participating the BBB was
a great success. O.J. was a blast to see...Scary
Fast.. The Freedom is coming along..The new crop of
EVers from the high schools and universities are going
to teach us all in just a few years as their entries
were impressive.  hope to see much more intrest and
participation from the list at up coming EVents. 
Events like this are such a great venue to get the
word out and exchange information on EVs and Hybreds.
thanks
again

  Mars Electric LLC is making a brushless DC motor with similar mounting to the

They have quoted me $450 for the motor with either controller. The motor is 
rated at 4hp continuous (less than the Etek) but I think the limitation is in

Someone on the list asked about the Rav4ev auction that disappeared from
ebay a few days ago ... it was a like new unit with 12k miles located (I
believe) in S. Cal.

 

The auction closed on Sunday for $61,600 on ebay to a buyer from Seattle.
The auction apparently "disappeared" after it closed due to an internal ebay
issue, not related to the auction.

"150 kmph"

Do you mean

150,000 mph?
150 km?
150 miles?
150 km/hr?
150 mph?
150 kWhr/mi?

No matter what the answer, a Jeep is one of the worst aero cars you could pick, 
and the 4WD adds drag and weight.

Hi All,

I would appreciate if someone could explain or give me a link to answer
this question.

How can a PMDC motor coast efficiently? Wouldnt the magnets slow down the
rotor and convert the energy to waste heat? How do all the cars like Prius
work on coasting then?

Thanks

My dummy load is a couple of heating elements from derelict heat pumps.  I 
modified them so they chew up 100 amps at 144 volts and put them in a large, 
old metal mailbox (really!).  Then I mounted a fan from an old range hood at 
the end.  It has a contactor for easier use.  Does a fine job of heating the 
garage on those cool autumn and winter days.  

One of these days I'll have to post a photo.  Some folks might find it kind 
of entertaining. ;-)

As long as there's no load on the output of the generator there will
be no power generated. The only losses you get are iron losses due to
the rotating magnetic field magnetising and demagnetising the stator
iron. Compared to induction motors they don't coast efficently but the
actual losses are almost insignificant.

Hi All,

I would appreciate if someone could explain or give me a link to answer
this question.

How can a PMDC motor coast efficiently? Wouldnt the magnets slow down the
rotor and convert the energy to waste heat? How do all the cars like Prius
work on coasting then?

Thanks
JJ

99% pure is not impressive at all. Some tap water is near that. That's 
still 1% mineral content! Also, these results are not well specified 
and not really guaranteed over the life of the product in the field.

Something's wrong if your distilled water is $2.50/gal. Should be like 
$0.59. It doesn't come in a lot of pricey brand names, distilled is not 
marketable like "spring water".

Note that "bottled water" (Sparkletts) and "spring water" are not 
distilled and should not be put in a battery.

David,
   Sushrut probably means the Mahindra Jeep made in India which might not
be a 4WD and might not be all that heavy too. Confirm that Sushrut.

No matter what the answer, a Jeep is one of the worst aero cars you could

David,  kmph means km/hr.


Sushrut, how much does the vehicle weigh?  Where are you located?  How far
do you need to go? How much money do you have to spend?

Gensets typically are a poor choice for an EV.  Check out the archives (see
the link below), search for genset, lots of discussion on how well/poor they
work.

Take a look at the FAQ (see link below) to get somewhat familaized with EVs
and their capabilities.

Also, take a look at my website or www.metrcimind.com on build an EV with an
AC motor.

A *big* one! :-)

For that speed in a heavy vehicle with a lot of wind resistance, you will probably need a 100 KW or more AC drive system (motor and inverter).

I have just found a jeep chassis.
I am going for AC motors.
I am thinking of a Honda genset.
Can such a genset power my ev?

It can provide sufficient power for driving at very low speeds, or it can recharge the batteries if left running for hours. But it is going to take 40-50 horsepower to maintain 150 KPH in such a vehicle. That is a big genset!

What technicalities should I look out for when designing my EV?
I am a beginner so any and all information is useful.

There are a lot of details, but they can be dealt with if you are persistent. I think your first step is to read everything you can find on-line, and in books about building EVs. Mike Chancey's "EV Tradin' Post" has lots of examples of the EVs that people have built. Use them to get ideas for what is possible.

And, you found the EV list. It is one of the most valuable resources for getting answers to questions. Just be aware that you will get *many* answers; some good, some bad, and some just plain clueless or even rude. Be patient; understanding will come with study.

There is no reason to use anything but distilled water- which is both "perfect", readily available, AND dirt cheap, at least in the quantities that an EV would need. It typically has virtually zero impurities and is of a very consistent quality even in the Wal-Mart store brand. In fact I see no reason to prefer any sort of name brand, distilled is distilled so get the cheap stuff.

I'll look at the Sears water purifier (what makes it different from my

distillation.

Matt,
Where are you buying your distilled water? I
typically buy it in one gallon jugs at the local
grocery store. If I can get the house brand on sale
it's about .89/gallon. If I have to spring for the
name brand stuff, Sparklets or some such, it's about
$1.29 a gallon. Who knows, we pay more for gas out
here in Southern California, so maybe they give us a
break on the water. I go through about 2 gallons month
on my 24 battery truck.

In the conversion that I'm now doing, three of the five battery boxes are
designed to hold two levels of batteries.  I am now experimenting with
various materials for use as spacers between the lower and upper levels.  In
other words, I will be using blocks setting on top of the lower batteries as
supports for the upper ones.
Recent trials with plastics showed interesting results.  Polypropylene and
ABS were both stuck to one of polycarbonate battery cases using 3M high
strength adhesive transfer tape.  The inexpensive polypropylene did not hold
a bond near as well as the more costly ABS.  So ABS wins out for it's
ability to stay put.

After a lot of fussing, my thoughts went back to good ol' wood.  It seems
that a solid and stable hardwood would give decent performance if the
environment remained mostly acid free. So I guess that is the question. Is
it unwise for me to consider using this organic material because of its
susceptibility to deterioration?  These quality AGM's sure look
unthreatening at this point. What do you think? 
Many Kw's of appreciation for your thoughts!

Note- The boxes are vented and I am building a killer charging system that
is a combination of PFC-30 for bulk charging and ventilated Soneil 3-amp
modulars for finishing.

You are correct; PM motors have full magnetic losses regardless of whether they are powered or not. So, they are more efficient at full load (because no field power is needed), but less efficient at light loads (because you can't weaken the field).

Vehicles with PM motors like the Prius just accept the no-load loss as a fact of life.

I think it is obvious that David knew what the poster intended it to
mean, but was pointing out in a tongue-in-cheek manner that "kmph" is
*not* a standardly used (or understood) abreviation for kilometers per
hour.  The abbreviations in common usage are "kph" and "km/hr".

"kmph" would actually seem to be the correct abbreviation for "thousand
miles per hour", though values of this magnitude would likely only
appear in the context of an astronomical discussion and people having
such a discussion would be more likely to use standard SI units ;^>

Cheers,

Roger.

It would require a pretty decent thickness to make a battery box out of, unless there's metal beams under it or something that lessens the span.
