From the second link, an apparent confirmation of speculation here about the temperature monitoring:
The battery control system will have sensors to monitor the temperature and voltage of each individual cell rather than the battery as a whole, one source said.
(Although I find it hard to believe that the existing system did not in fact monitor individual cell voltages somewhere along the way.)
I do not think any EV or other high total-energy use tries to avoid monitoring individual cell temperatures or does not at least use temperatures more closely linked to cell temperatures than the Boeing design does.
Even if it would not allow effective corrective action, at least it could deliver early warning and perhaps reduce the contribution of external charging power to the spread of thermal runaway. If the system did not detect the short of a single cell and raise an appropriate warning, it may not have disabled the charging attempt either.
