I think people get confused with the term balancing. It is pretty much a carry over from lead acid batteries where the take all the cells to boiling to get them to the same voltage at the end of charge. It doesn't apply to Lithium since this is derogatory to cell life. I believe what people are experiencing is the algorithm built into the system that keeps up with capacity from all the data, current, voltage, sag, internal resistance, temperature........ after a while of short discharges and charges the capacity value can get off from actual battery capacity and it gets corrected when you do a deeper discharge. If any balancing is going on it happens every time you charge... most likely or when close to fully charged. Maybe some guys who actual take cell data can shed some light on this but I don't think this is affecting capacity much.

Lost capacity may be restored by “balancing the pack”—that is, charging it to 100 percent to make sure that each of the cells is fully topped off. Tesla, of course, is mum on the subject; I’ve never seen any official word on pack balancing, and the company officially recommends against charging to 100 percent unless maximum range is necessary. The Model S fan site Teslarati, however, recommends charging the pack to 100 percent every three months or so. When I asked at my local Tesla Service Center about “pack balancing”, I was told they did it all the time. “Discharge it as close as you can to zero, and then charge it as slow as possible all the way up to 100 percent,” I was told. “You’ll probably get some capacity back.” It works! ... and comments on this topic are shown on: http://electric-vehicle-discussion-list.413529.n4.nabble.com/template/NamlServlet.jtp?macro=search_page&node=413529&query=tesla+pack+balancing&days=0 For EVLN EV-newswire posts use: http://evdl.org/archive/ {brucedp.neocities.org} -- Sent from: http://electric-vehicle-discussion-list.413529.n4.nabble.com/ _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA) -------------- next part -------------- An HTML attachment was scrubbed...
