72V Curves, Tysonic, Charger, Motor, Deployed PV 3-D models

September 17, 2009

I have several updates today:

• The Factory Service Manual is on backorder and I would still rather wait for it before beginning to disassemble the gasoline power train.


• I discovered another sealed lead acid AGM battery option from Tysonic that is significantly cheaper than B&B and fits perfectly into the available space. It would provide similar range as the Lithium Ion pack I am considering, at one third the cost, but its life may be up to a tenth shorter than Lithium Ion and the range will suffer degradation throughout the batteries life. LiFePO4 is still the better value. I also created models of the new battery option, battery charger, motor, and deployed PV panels. See the video for more detail.


• Todd Kollin at http://www.electricmotorsport.com/ and John Fiorenza at http://www.marselectricllc.com/ were very responsive in emailing me the 72V performance curves for the Etek-RT (ME0709) motor I will be using. I haven't yet studied the curves in detail to begin my performance estimates and to select the proper gearing and top speed targets.
