October car shows

Sparky went to 2 local car shows Oct 3 and 4. See pictures of the cars I found interesting, see the Oct8CarShows album at http://stormc.smugmug.com/
Anyway, I created 5 mini posters which were glued to the back of a sheet of acrylic for display on the hood as seen in this picture. Just for documentation, I will copy them here. Ideas for improvement are welcome, and you are free to use any or all for your purposes. They were created using Word. I could email them to you if that would help.





Why Drive an EV?

This vehicle goes 2 miles per KWH of electricity. Even with the high cost in Corrupticut that is still less than 8¢ per mile.

What is the real cost of gas?

Fuel charge? Military expense? Medical expense?

Environmental cost?

Does it make sense to buy gas from people who hate you?

Want energy independence? This is a true multifuel vehicle. With my solar panels I can drive on sunshine.

The fuel infrastructure is already in place.

Eliminate tune-ups, oil changes, and muffler hassles.

No emission tests.

How far would you drive if your exhaust came out of the steering wheel?

A pitch for the NEEAA. The logo was at the top, but it doesn't seem to want to copy here :-(

Our active EV club generally meets at 2PM on the second Saturday of the month in Killingworth, CT. You’re invited to join us. See the web site or call 203-530-4942 for details.

Sparky is # 1059 of over 2000 EVs detailed at www.evalbum.com



To answer the inevitable question

$$$

How much does it cost to convert?

Much depends on your scrounging ability. Scrapped fork lift trucks can supply some parts. If you are buying new parts, the shopping list would include:

Motor $2,000

Controller $1,500

Batteries $1,500-$20k

Charger $30-$2,500

Battery Boxes $???

Motor/Trans adapter $600

Instrumentation $200 and up.

Misc wire, fuses, etc. $500

Parts are expensive because of the low volumes. Imagine building a Buick with parts purchased from the service department.

Electric Vehicles of America in Wolfeboro, NH

www.ev-america.com is the nearest supplier.


And finally,


Get a charge FAQ

How long does it take to charge?

This car has about 15KW of usable energy in the battery pack. That means that if the pack is low, about 15,000 watts needs to be returned. How long it will take depends on how much power you have available if your charger will handle it.

Ø A 240V 30A dryer outlet could do this in 2 hours.

Ø A standard 120V 15A outlet would require about 9 hours.

Ø A 190 watt (3’X4’) solar panel mounted on the car’s roof could charge it up with 79 hours of full sunshine.

Regeneration would use the motor as a generator to slow down thus saving the brakes as well as charging the battery. If I could do it, it would increase the range by about 10%.

Mounting a generator to the wheel or a windmill on the front won’t do anything positive. The energy to turn these things would ultimately come from the batteries which are causing the car to move. The charge they would return would be less than the drag they created. See “conservation of energy”.


Anyway, a lot of people found Sparky of interest. Trying to format on the blog is still frustrating! Importing a copy of a Word document is not a good idea! Way too much formatting info that has to be removed. The posters are better looking than they appear here.
