style='font-size:10.0pt;font-family:"Arial","sans-serif"'>We have a couple of
EE’s with experience in this sort of thing in the club who are starting
on a project to make a LiFePO4 battery system suitable for EV’s.
Tentatively these modules are expected to be about <b>4.5KWhr, 75VDC,
300Amps</b> max continuous, <b>600Amps</b> peak, with <b>22.5Kwatts</b> (29 hp)
continuous power. Modules can be series or parallel connected just like
commercial batteries. DC motor EV’s would probably take two modules
in series for 150VDC, 9KWhr capacity (@ 250W/mi — 36 miles). A higher
voltage AC system could use three or four in series. A more
powerful DC system, or if you want twice the range, could use four (150VDC,
18KWhr.) in series/parallel. Each module will be fully enclosed and
protected; yet individual cells can be easily replaced. Full BMS will be
built-in, with remote SOC/SOH display. The system may also have a
built-in battery charger and possibly a DC-DC converter (for 12V battery)
depending on what everyone agrees on.</span><o:p></o:p></p>
<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span
style='font-size:10.0pt;font-family:"Arial","sans-serif"'>This is a big project
expected to take most of 2009. The predicted price of the modules is
currently $6,000 but subject to change as things are further defined. Our
desire is to be less expensive than other LiFePO4 systems available to DIY EV
builders, but of high commercial quality with safety as first priority.
To participate in the project, a contract, NDA, and earnest money will be
required. There will be a schedule for payments throughout the year as
major milestones are accomplished.</span><o:p></o:p></p>
<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span
style='font-size:10.0pt;font-family:"Arial","sans-serif"'>Is there interest in
this from members of the Austin EV list in particular but not limited to those
that are close to the Houston area. The cells are being bought in
quantity and building more modules lowers the cost of cells and the
proportional costs of getting the electronics made.</span><o:p></o:p></p>
