This report presents a study performed on a set of common-cause failure (CCF) events for batteries within the International Common-Cause Failure Data Exchange (ICDE) project. In September 2003, the ICDE project published a report summarising the collection and analysis of data from 50 battery CCF events. Since that time, the ICDE project has continued collection of battery event data. The database now includes 85 events spanning a period from 1980 through 2019. However, the data are not necessarily complete for each country through this period.
The report is mainly intended for designers, operators and regulators to provide insights of the type of failure mechanisms and causes of the battery events in the ICDE database. The insights can prove valuable to support and improve the understanding of failure mechanisms and phenomena involved in the events, as well as their relationship to the CCF root cause, and to provide possibilities for improvement within multiple areas.
