More benign scenario?

cwatters,

This is just one of the things that the charging circuit will check (eg that it's not too empty to be charged safely).

And additionaly, a tweaking of the algorithms is likely to be required to increase the reliability of the Battery System (Battery + management System)

This may explain severity of BOS incident and characteristics of TAK one. What was common to both? The battery type. (probably the management system too).

Excellent link you found
