Swan TAFE eV Challenge 2007

PS. Congratulations to the rEV Heads for the overall win
I can't think of a nicer bunch of guys.
They were modest before the event and generous after it.

Swan TAFE eV Challenge 2007

Hi All, I have just read this thread with some interest. I entered a cart in the YUASA class last year and with the help of Andrew and Tuarn Brown we drove to 2nd place. Not bad for a bunch of mugs. I didn't see any other WAEVA members there on the day so it looks like we have started something here...

New LiIon technology

Dave W. forwarded this link to me.
Looks like Lithium Ion could do even better range.

Does anyone know of a motor manufacturer that can produce a motor with the following specs? 250VAC three phase, air or water cooled 10-15kW continuous input 50kW+ pulse input 0-8000 rpm < 60kg I am convinced that the future of EVs lies with AC technology.

Silicon Chip - September 2007

I have done some calcs on this in the past. My EV consumes about 180Wh per km, wall socket to road. Roughly speaking each KWh from a coal fired power station produces about 1kg of CO2. So my car produces about 180g /km running on coal. It is the least efficient (read least expensive) conversion one ...

fast charging

People often ask me how long it takes to charge my EV. My standard answer is "10 seconds". When they have recovered enough to respond I explain that I drive my car during the day (range 60-90km) then plug it in when I get home at night. The power cord hangs from the roof of my garage and it takes 10...

Lithium Ion Batteries

Hi All,
This is my very first post!

LiFePO4 batteries have a life cycle of 1000-3000 deep cycles.
Suppliers are currently offering warranties of 1-3 years which is pretty good.
The only issue is the cost, about 3-5 times lead acid.
