Unknown future problems? What are you referring to? This is well documented failure mode. That is the very reason of having the fuse there. :) It is not due manufacturing defect.
Empirical evidence is empirical. One has to see it with own eyes. It does not mean it is in public domain. Most important to make it scientific and useful is to have all well documented and verified with proven evidence. This is what Tesla is doing by not telling openly what is their empirical evidence on the drive battery failure modes. It's their way to keep ahead of the competition. Just like what I have been doing for the past ~20 years in this field of business. I use the knowledge to improve my products and innovations to create more innovations and make sure we survive the climate change (while it all started with deep love to EV and technology 25 years ago). 15 years of operational lifetime has been now proven with LiFePO4-Graphite. Adding the new innovations on that base track record is basis on my claim we are going to witness even better results. This is why I *see* this as a *possible* outcome. 500Wh/kg can be achieved in printed thin film cells which have been plagued with certain issues regarding certain things. Vague enough? :D -Jukka su 9. syysk. 2018 klo 21.19 Jan Steinman via EV ([email protected]) kirjoitti: > > From: Jukka J?rvinen <[email protected]> > > > > The main question is when will the problems be there?
