[ausev] Z3 Conversion Starting

[Charles Birkhead]

One already exists.  Try
http://www.geocities.com/CapeCanaveral/Lab/8679/evcalc.html. 

I have modified it to include internal wire resistance and idle current
drain.

All,

I like the idea of having an 'calculator' of sorts that can give a rough

estimate of EV performance based upon the design. If people are willing,

maybe we could find an 'ideal track' of sorts and start gathering data 
on everyone's EVs and their designs to back up the models.  This track 
could just be road somewhere in Austin, or something with 
defined/controlled starts and stops along with continuous driving, etc.

My interests kind of lie in modeling of dynamic systems in general, and 
modeling the cars and confirming the performance with respect to 
batteries, voltage, weight, different motors, and such would be a good 
idea.

Maybe we put a log of information on actual car performance stats on the

Austin EV site.

FYI I've been trying to recontact the potential source for donated cars 
for EV conversions from the car donation program, and he sounds 
interested but claims to be too busy to think about it much. I'll keep 
politely nagging him.
