Hello All,

I'm sending this on behalf of Harold Miller:

Call for Judges, Suggestions, and Ideas for the NEAT Event (Northampton,
NC area)


Harold Miller of the Roanoke Valley Electric Vehicle Association is
asking for judges for their NEAT EVent on November 19^th and 20^th
(Friday and Saturday). This Event is very similar to the old EV
Challenge of which Harold was a founder. Each day's events will take
place starting at 10am at the North Carolina Center for Automotive
Research (NCCAR), an automotive product research, testing and
development facility being developed on a 620-acre site just off
Interstate 95. Participating EVs will be allowed to drive on the new
NCCAR 2.5 mile track. Students will have access to the classroom.

For volunteering and coordination information, please contact Harold at:
[email protected]
<http://mrd.mail.yahoo.com/compose?To=ev%40schoollink.net>

The track can be easily seen via Google Earth. It is NE of Roanoke
Rapids and NW of Garysburg; just north of a horrendously big Lowe's
Distribution Center (loaded with parked semis).

Directions:

To get to the NCCAR track, take I-95 toward Roanoke Rapids. The exit is
just north of Roanoke Rapids. Exit east onto Route 46 toward Garysburg,
NC. In about 0.2 miles, turn left onto Lowe's Blvd. Follow the signs to
NCCAR and the NEAT Event.

Request for Suggestions and Ideas

To make things more interesting for all, Harold is also requesting
suggestions and ideas to make this a more educational EVent for the
students

One suggestion is to record the amperage draw at each 10 mph increment.
Then compare it to what would be expected for aerodynamic drag. What is
similar and what is different about the curves? Is there a difference
with the drawn curves when a pack is fresh and when a pack is just about
depleted?

Another idea would be to measure the heat produced by each controller at
different speeds. For that, he would need a thermistor bead Duck
Tapeable to each controller and tied into a read out device with ample
cable stretching from under a hood to inside a cab via a window. If
anyone has experience in creating such a device, please reply to this
email. This is something that I know I can get funding for. The students
can also learn to calibrate the instrument(s).

Any additional ideas or suggestions will be welcomed.

Hello Peter,

I have assemble several types of temperature display units, using the
standard auto and/or building heater units devices.

The first one, is auto coolant and sender to measure the water temperature
of a water cool controller. Install the sender on the out port on the
controller.

Next I use thermo couple that is use in gas furnaces that is use to detect
the present of a gas flame. These units generate a current when heated. I
connect it directly to a standard Stewart Warner coolant display meter. I
use a meter that has a temperature test mode to adjust the temperature by
installing a variable 0-100 ohm resistor in series with the thermo couple to
the display meter. It is bolted to the heat sink.

I now use a Stewart Warner 0-600 F. meter with has its sender that is use
for engine temperature. It can be bolted to any bolt on a heat sink or the
motor.

The simplest one, is a indoor-outdoor thermometer that I got from Wal-Mart.
It has a 6 foot sensor lead that can press stick to any surface you want.

Roland
