Hi All, I just hit over 30,000 miles on my 1969 VW Bug Conversion: http://www.corbinstreehouse.com/blog/plug-bug/
General info: 48 200Ah Thundersky LiFePo cells. Elithion BMS. No heating or cooling of the cells. Santa Cruz / Bay area California location. Warp 9 / Netgain controller. Roughly 3 years on the road. Daily commute: about 40 miles. I generally charge just at work. I generally charge to 100% SOC...which I don't think is all that good for the cells I'd like to tap into the BMS canbus and limit the charge at 95% SOC unless I need a "range charge". I charge to about 3.6 or 3.7v (I can't remember what I have it set at right now). I replaced a dying cell last year: http://www.corbinstreehouse.com/blog/2012/12/plug-bug-bad-cell/ I have another one that is starting to sag really badly, but I'm going to wait until it is truly dead before I replace it. I've taken my pack to 40% SOC and it still is over 3.1v when sitting, so it probably has 70% of its original capacity. However, it sags heavily and sets of my BMS alarm if it is really cold out (ie: 50-55F, which is cold for California) -- mainly, it is the bad cell that causes this. My blog is in chronological order; definitely check it out if you are curious about details. -corbin _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
