B787 battery
Looking at the CT scans it appears the metal cases are touching & the internals are pushed out of shape which results in shorts everywhere!! Nothing would protect the pak if that occured & the charge circuit continued to provide a nice stable 30 V into this mess. It would not be a good thing to continue with this type of cell if could short out to the case & the metal box containing the cells !!. There is some idea not to float charge Li Ion but to charge then disconnect until needed. Could this get the aircraft back flying if the battery was isolated for flight? After all this is not reliant on the battery for systems in flight. It is still available for the energency case if required. I would be pleased to help Boeing further all they have to do is call me.
