Any clues of how the Li-Ion batteries in the Boeing 787 caught fire?

Just curious. Is this the same problem Sony had in their laptops?

Update:

Rick: I saw that article too. But it would be bone stupid to allow overvoltage of a Li-Ion battery. So I doubt that is the case. The circuitry inside the battery pack should prevent that.

    I just saw an article that said the voltage was to high. Clearly, this means it was either overcharged (with overvoltage) or something went wrong with the balancing circuits. Li-ion batteries are very sensitive to overcharging.

    Nobody knows for sure, at least nobody who is speaking to the press.

    Lithium ion batteries are unstable. When overheated or overcharged, they can catch fire.

    I'm really surprised at the design choices the Boeing engineers made.

    I heard it was just the size. Lithium ion batteries are very energy dense, and have very unforgiving behaviors on charging, overcharging, or anything but kid-glove treatment on installation / handling.

    So "yes, like that".
