The way I see it, it's inadequate oversight of the complete battery
subsystem by any sufficiently qualified and experienced engineer. Perhaps
that's what happens when you hand over the company to beancounters, who
then fire all the older engineers who really knew what they were doing
and understood the meaning of the expression "due diligence".
What is interesting is why Yuasa, who know how these cells need to be
managed, didn't raise questions about the design, but perhaps they did
and were overuled. Hopefully the final report will be more enlightening.
Glass is half full though, right ?. It will be fixed and be a better
a/craft because of it...
