Boeing Plans Battery Redesign to Get Dreamliners Airbone Again | Frequent Business Traveler
A couple of weeks or so ago, I was trying to determine if each cell
had it's own associated temperature sensor, rather than one to cover
the whole enclosure. The following from the above article suggests that
there may *not* be one per cell:
"Boeing may <snipped> possibly add better heat sensors".
I seem to be the only one out of step here, as everyone else
still seems to be obsessed with the battery and it's construction,
but there are other possibilities to consider.
Still think that the battery would only fail in such a way if it
were abused, which suggests either operation outside cell voltage
limits, or inadequate cell temperature sensing, during fast charge
or high current load.
Might need just a software mod to fix, though after all the hysteria
only an ejectable, fully armoured enclosure would
be good enough for some
