[ausev] EV w/300 mile range

[Jeremiah Brown]

I've been "list lurking" (partially because I was living in New Zealand when I first got on this list, currently in the process of moving to Austin) but I feel compelled to comment on this thread. 
   
  How much of the $35K price tag of that car is the battery? As most of us are probably aware Lithiom Ion batteries are not cheap, not to mention they have a tendency to explode when you overcharge them. Although I guess that's no more dangerous than gasoline. 
   
  The energy density of a lead acid battery is something like 1/45 that of gas. I really feel like the biggest mistake being made with electric vehicles is that people keep trying to make full sized cars but the battery technology just isn't there yet. 
   
  I used to ride a 200W folding electric bike to work when I was living in Christchurch. It was a little slow until I added an extra battery to make it a 48V system and get a little extra speed. Even with the extra battery it was only using about 400W (based on current measurements from the battery and estimating the efficiency of the motor) which is still mush less than 1 horse power. There are lawn mowers with more power than that bike! However, this was sufficient to get me to work and back and even carry a few groceries. What's the typical horsepower of an electric car?

        The title of that article, "Lithium-Battery Cars May Deliver 300 Miles Per Charge", implies that is a sought after engineering goal - "May Deliver".
   
  The T-Zero goes 300 miles per charge now...  And is no slouch while doing it!

Have enjoyed following your conversations about EV's.  One of these days, I would love to start a project, but for the time being I'm learning what I can.  My son knows I'm interested in EV's
 and he forwarded this article that might be of interest to some.
