The problem with Tesla's batteries is not small vs large but Tesla has put all their eggs into one type of battery. The other automotive companies are staying out of the battery business so that they can buy the best batteries available and not spend money on development. Vertical business development is not always the best model. At present, do what you do best and assemble a final product and buy from numerous suppliers is the current business model for the big automotive companies.

How can you criticize one manufacturer for unknown future problems who uses known technology, while lauding unknown technology for a long lifetime that none of it has even passed through? We have all sorts of empirical evidence with small cells. MTBF behaviour is well characterized. But there is absolutely NO empirical evidence for "15 year lifetime" of "solid state electrolyte and synthetic Graphene" cells. Personally, I prefer nickel-iron cells. But I'm an outlier. :-) Jan _______________________________________________ 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...
