re: Active balancing boosts HEV/EV Li-ion battery utilization: Part 2—Methods
PH Eng   12/16/2010 3:17:18 AM
I'm very interested in the BMS circuit board mentioned in the full article (on Automotive Designline Europe), but I couldn't find any information on NS' web site. Does anyone know whether it's commercially available?

The author just provide a too simplified idea on this topic. Active balancing is a very hot topic in BMS field and I know many companies are actively design solutions but none is successful yet. If NS is really doing good thing here, I hope to see some more details on the design and see how robust and reliable this solution is.

With no offense to the writer, i fail to see the usefulness of this article other than promoting the new chip. It just highlights the obvious problems faced by the series architecture and some cumbersome solutions which were proposed in the past. It would have been much appreciated if the internal functional diagram of the projected chip was discussed and possibly with an example case-study.
