Claim 41:
42. A non-transitory computer-readable storage medium, the non-transitory computer-readable storage medium storing instructions to be implemented on a controller within a battery pack having a first lithium-ion battery cell, the instructions when executed by the controller provide a method for:
detecting an imminent catastrophic failure of the first lithium-ion battery cell, wherein the battery pack further includes a first magnetic surface configured to attract metallic debris associated with a catastrophic failure of the first lithium-ion battery cell; and
storing a timestamp in non-volatile memory associated with the catastrophic failure, wherein:
the battery pack further includes an electronically controlled vent electrically coupled with the controller; and
the method further includes closing the electronically controlled vent upon detecting the catastrophic failure of the first lithium-ion battery cell.
