Each cell is operated in specific SOC window (say 70%DOD between 20 and 90 %SOC) which is matched to other aging mechanisms. So each cell has its own operational SOC region. Another cell might be used between 25 and 95 %SOC and another between 15 and 85 %SOC.
Effectively reducing certain amount of capacity from the pack but cells are 'driven' to more balance. So balancing does not mean one has absolutely same SOC on each cell. Voltages might be all over the place as the balancing criteria is matched lifetime and service predictability. -Jukka ke 9. elokuuta 2017 klo 23.29 EVDL Administrator via EV <ev@lists.evdl.org> kirjoitti: > On 9 Aug 2017 at 20:18, Jukka Järvinen via EV wrote: > > > This is why SOC windowing was developed. > > Could someone please explain what SOC windowing is and how it works? > Thanks. > > David Roden - Akron, Ohio, USA > EVDL Administrator > > = = = = = = = = = = = = = = = = = = = = = = = = = = = = = > EVDL Information: http://www.evdl.org/help/ > = = = = = = = = = = = = = = = = = = = = = = = = = = = = = > Note: mail sent to "evpost" and "etpost" addresses will not > reach me.
