How have battery management systems not evolved to deal with this issue? It's especially confusing considering the massive number of laptops deployed by companies to part time work-from-home employees many of whom keep their devices plugged in nearly 100% of the time.

They haven't evolved to stop issues happening, partly because many a consumer won't understand the need so won't accept it (I'm returning this because it never charges to 100%) and there isn't enough demand from elsewhere for it to affect sales of devices (in office environments those laptops are usually cycled out before it would be a significant issue anyway).

But these days there are often controls in place to cut off power if things look bad (battery getting too hot, mainly) so things are more likely to die on their own rather than setting fire to themselves and anything near-by.

That battery doesn’t look any different to the BMW under catastrophic failure conditions.
