摘要

Fault tree analysis has been used by engineers as a means of defining system failure. It provides a method of system examination which increases the level of understanding of the system and is helpful in logically determining the underlying causes of potential failures. A fault tree is composed of a number of symbols, describing different types of events, which are operated on by logic gates. Construction of a battery fault tree is discussed in terms of two types of event and two logic gates. An example is given of how fault tree analysis was used to determine the cause of a safety incident. A string of lithium cells on test for several years suddenly vented violently. Fault tree analysis quickly pointed out the underlying faults leading to this event, and a means of prevention was suggested. 1 ref., 3 figs.
