Tesla 12 or 16V battery fire while being charged off the car indoors: https://www.wral.com/story/tesla-battery-explodes-in-cary-home-after-being-removed-and-charged-inside/21256187/ I'd bet that the BMS was bypassed to charge this Tesla LV battery. This is just not safe. A BMS will brick a battery for safety reasons. Never try to revive a bricked battery. Instead, bend over, grab your ankles and buy a new one. It still works out far cheaper than a house.
OK let's be clear here. It was not the traction battery which caught fire. It was the 12V battery which I believe is lead/acid. These can give off hydrogen gas when being charged from a very low state. It wouldn't need to have an internal short circuit (although it may have) to cause an explosion. Hydrogen gas wafting into the pilot light of a gas appliance would do it. Of course because a Tesla was involved it makes for sensational news once again falsely promulgating the idea that EVs catch fire more easily. If it was an LI battery then a bad cell may well have been the cause.
