I remember something like this happening to notebook PCs equipped with SONY batteries some time ago. http://www.businessweek.com/technology/content/sep2006/tc20060929_795562.htm. Li-Ion batteries that you find in modern notebook PCs and mobile phones explode when overcharged. That's why every Li-Ion battery sold have internal circuitry to cut off charge when the battery is full. Faulty/failing circuitry might cause said notebook/mobile phone to burst in flames when charged. Another possibility would be faulty batteries that induce short circuit inside the battery pack.
