The other EV...
My second electric car was a Toyota Paseo. Originally
converted by US Electricar and upgraded by innEVations (Gary Flo)
with a new Auburn controller and more batteries. It had an Auburn
Scientific Grizzly controller which can pull 600 amps at 192 volts.
It can do 0 to 60 in about 10 seconds. Here are some interesting
specs:
Voltage
|
192 (16 - 12 volt optima batteries)
|
Maximum Motor Amps
|
600 Amps, 350 except under the best conditions
|
0 to 60 in
|
About 10 seconds
|
Range
|
35 miles in a combination of highway (65mph)
and city (45mph with stops lights) in the summer.
|
Charge Times
|
80% recharge from completely dead in 1.5
hours
|
The car had three Zivan charges on board. One 110
volt and 2 240 volt chargers. With all three working together that's
about 26 amps of charging capacity. It had 16 Optima yellow tops
and a micro-processor Auburn Scientific Grizzly controller.
I just installed two roof mounted flexible solar
panels on the roof of the car. The stick up about 3/16 of an inch
and power an exhaust fan. That keeps the car a little cooler on
those hot summer days. It really makes a difference, especially
since I didn't bother with air conditioning.

Another cool little toy on the car was the
PalmPilot. I wrote some software
that reads input from the E-Meter and displays the current
voltage and amperage in big one inch high characters. It also
calculates the state of charge using two methods; the rest
voltage and the power used. The power used calculations use
Peukert's constant. Both state of charge estimates are shown
with a bar type display. A big improvement over the 4 LED
approach of the E-Meter.
After collecting the data with the PalmPilot
I plot and analyze the collected data with a Java program.
The graphs look like the picture below. There is also some
text that it spits out that allow me adjust the parameters
in the Pilot. Using the graphs and text I can adjust the meter
for colder temperatures. The cold has a significant effect
and the capacity drop to half of what it is in the summer.
