Those diesel engines (at least the 5 cylinder ones) are also very
heavy.....as much as an american smallblock V8 I think. Should free
up some weight for batteries too.

Are you sure you want such a heavy and un-aerodynamic car to be the basis of
something electric? Even in diesel form it only managed 30something mpg...

Vacuum locks are the mose inefficient, vacuum motors are pretty expensive
and a solonoic electric door lock and stepper heater controls are a lot more
efficient, that's why all the german machinery use them now among other
reasons. Also your drive train has got a 90 degree kink in it - the back
axle - making it less efficient than a transverse engine layout. Expect
25-30% loss from your motor eaten up in the old heavy oil, non-roller
bearing gearbox with it's drag creating helical gears...

Of course if you really like the old mercs and you are only wanting to ever
go a very short distance (till they invent the flux capacitor battery) then
it's cool. Gonna cost you a fortune in batteries just to get a 10 or 20
mile range if my calculations are right :p

Good luck though, you'll have something different that's for sure!

Greg.

I would only try to convert a car with a manual Transmission. These were
ment to be economy cars (the 240D) so many if not all have a manual tranny.
It may seen like I am trying to do something difficult, but the way I see it
, this should be easier to convert. (of course I am a noob!) I do have a
300D which is very similar so I can see what I think are some advantages.
Much of the car works with vacuum, like the door locks and heater controls,
and brakes, so a vacuum pump would do many functions. They have manual
steering, which I see as a real plus, it will steer like a normal car with
no messing around with extra motors for power steering. The car is RWD and
the diesel is a very tall engine, so the electric motor would sit way down
low in the engine bay leaving lots of room for batteries in the engine bay.
It has a huge trunk so there is room for batteries there as well.

My thoughts are to convert it now, and only use enough floodies to give it
the performance of a NEV. Then in a few years, if/when better batteries
ever become available, I could upgrade and have a pretty decent EV.

But again, I am a noob, and there might be something obvious I am
overlooking that makes this a bad project to take on. I appreciate all the
feedback

Thanks

Peter

You know, I think that that car is a modified Avanti. The front and rear cl=
ips sure look like it. It's a fascinating specimen.

Thanks for the inputs, I can charge at work, the problem is the 20 mile run is almost all up hill. Looking at the EU3000i generator spes, it claims .47 gallons/hour at rated load, 23 amps at 120 volts. That's enough to feed the PFC 20 what it needs. The run would be less than an hour, that's less than half a gallon a day. This would be worse than burning ~1.2 gallons in my V8 ICE? I guess a catalytic converter makes a big difference. I will be trying a different somewhat longer, but less hilly route home tomorrow. Fortunately there are several charging stations I can stop at on the way home. I just don't want to make a 45 minute charging stop a part of my daily commute. Is there routing software out there that can route you around hills? I need to check the bicycle web pages and see if there's anything like that available. I use the avoid highway option regularly an avoid uphill option would be pretty nice if I can find it.

No, it's definitely not an Avanti. This looks like a custom made
fiberglass body on a McKee Engineering's Sundancer-type chassis. It is
similar to a car McCulloch Enterprises built in 1974.

You could try this:

http://maps.google.com/support/bin/answer.py?hl=en-ch&answer=68476

It didn't work well for me- I was looking at the Seattle
"Terrain" view (I know where Seattle's hills are) and found it
difficult to discern the lines and shades. Your mileage may vary,
especially if you have a nicer monitor (mine is 8 years old).
If you find something better, please let us know! (Or me, at least ;)

That EU, or any inverter generator for that matter, is poor economy for
battery charging. You'll have the generator either fully loaded or off so
there's no benefit to the variable RPM feature. Neither is the low distortion
sine wave of any benefit feeding a PFC20.

There are a number of limitations involved. Inverter generators cannot be
overloaded. The inverter protection circuitry trips and the generator has to
be stopped to resume generation. A regular synchronous speed generator, OTOH,
CAN be overloaded, sometimes significantly, without harm. This is especially
true if the output frequency and waveform quality doesn't matter. With the
adjustable current feature of the PFC, you can simply turn it to find the
maximum power point for your generator and operate it there. The frequency
may end up deviating significantly from 60 hz but that won't matter.

I do the same thing on a smaller scale with my RV. I drive a smart 80 amp
charger with one of those $100 1kw generators like Northern Tool sells. 80
amps at 14.5 volts, where the bulk/absorption transition takes place, is about
1200 watts into the charger. That's significantly more than the little
generator's rating but it handles it just fine. It slows a bit and the
frequency drops a few hz but it gets the job done. In contrast, a 1kW
inverter generator would have tripped off and would supply zero watts to the
battery.

Six months ago I'd have recommended one of the small diesel generators coming
out of China. Today with the wide price spread between gas and diesel, I'd
have to do some calculating. The diesel version will be more economical, more
reliable and will generally handle overload better than a gas version but
it'll cost more initially. I'd have to sit down with a spreadsheet to figure
out if the overall operating cost would be less. At the current local spread
of about 60 cents a gallon, it'd be close.

Paul-
How would I get a copy of your 144v controller schematic and
software? I'm far from a software expert (almost a hack) so would I
have to do any programming and if so, how would I so that?
Great accomplishment!!! Good luck.
Al

Subject: [EVDL] Chevy/ GMC Trux, Steering boxes ??'s
To: "Electric Vehicle Discussion List" <[email protected]>
Message-ID: <[email protected]>
Content-Type: text/plain; format=flowed; charset="iso-8859-1";
reply-type=original

Hi EVerybody;

Anybody ELSE gotten involved convertying Chevy S-10's? Duh!? About the
most popular truckee conversion out there. Question; Are ALL the steering
boxes the same or easily swappable as to bolting in? We are thinking of
putting a GMC '84 box into a 97 chassis. Hard to tell by just eyeballing
it.
Anybody done stuff like that? What do you DO with the power steering box IF
ya don't wanna use it, anyhow? I'm guessing you can't just remove the lines
and just CAP it, we TRIED that! Fluid TRIES to get out the holes when you
turn the steering wheel, as it is. IF you cap that ,I would think it would
make it HARD to streer, IF it would?

Personally, I would like to go manual, less crap to deal with and we're
only gunna have 4 battery in the former engine room.Maybe it won't steer
like a truck?

Seeya

Bob, EV meeting JUST starting up, beautiful day in CT!!

Continuing thr gm steering box if you have power steering just splice the
two lines together and the formerly powered box will steer nicely with a
little more torque from your arms. if you laiter add an electric pump for
the steering system the power steering works great. if driving unpowered
steering alignment is critical. I like 25%less than usual caster and half a
degree of tow in. IMHO Dennis
