DACI Newsletter Extra: More Lithium Battery Troubles?

flamingteslaA Tesla Model S electric vehicle, which uses lithium batteries, burst into flames after supposedly running over a road obstruction. The state trooper who investigated the event did not find evidence of an obstruction.

The car’s battery pack is located in the floor, so it is possible that an obstruction ruptured the pack. But without confirmation, it is also possible that the battery pack erupted in flames due to an internal defect, similar to the Boeing incidents. Low-probability incidents by their very nature will occur rarely, but when they do occur they can be deadly when associated with high energy storage system, such as battery packs.
