As a non-engineer I don't have much to contribute to this discussion. However, I might point out that from what I've read you're talking about designing a BMS for EVhobbyists, not for production EVs. IMO, that calls for a somewhat less stringent level of fault tolerance.
Safety is still critical in a hobbyist BMS, but it's worth remembering that EV hobbyists are infamous for their strong preference for low cost over reliability. It's a really bad idea for a production EV with a BMS fault to stop the car in the middle of a busy rush-hour LA expressway. For hobbyist EVs, though, not catching fire will probably be considered success. :-) 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.
