In part 1 and 2 of the article series Battery Failure Mode and Effects Analysis we identified that a battery mode and effects analysis is a procedure for identifying and understanding potential failure modes in a battery system. We found that a battery mode and effects analysis contains four main steps or phases including:
Battery Mode Pre-work - explained in part 1
Battery Failure Severity - explained in part 2
Battery Failure Occurrence - explained in part 2
Battery Failure Detection
Now in part 3 of Battery Failure Mode and Effects Analysis I will address Battery Failure Detection and wrap with a summary of the article series.
Battery Failure Detection
Battery failure detection is method of inspection that is used when examining failure modes within a battery system. The method of detecting a battery failure begins with a review of existing system controls that are designed to prevent failure modes. Next comes testing, analysis, and monitoring failures. The purpose of which is to understand why a particular mode is failing. When a failure mode occurs, a detection number that represents the likelihood of detecting a failure mode, is subsequently assigned, and after a series of detections the total number of detection numbers are collected and added together to give a total score of battery failure modes; the lower the detection number is the better the overall battery system design schema.
Remember as in all of the three previous articles it has been noted that the purpose of a battery failure mode and effects analysis is to identify and understand potential failure modes in a battery system. The reason why this is so important is that customers, who provide cash-flow (the lifeblood of a company), must be satisfied. Satisfaction as it relates to batteries is the lowest possible cost while still maintaining the best possible battery product. Thus insuring the lowest possible detection number is critically important to insuring the maximum potential of a company involved in battery design, manufacturing and sales.
Battery Failure Mode and Effects Analysis Summary
Over the last three articles we looked a battery failure mode and effects analysis and learned how helpful this procedure is for analyzing potential failure modes in a battery system. Discovering potential defects in a battery design or manufacturing process is extremely helpful in controlling business expenses and losses as well helping to make more efficient the overall battery development project. A battery failure mode and effects analysis is also closely associated with six sigma methodologies and is a proactive tool for reducing errors, reducing expenses, and increasing profits. Now you could probably find a failure mode and analysis software online or you can build a custom template (that would be my preference) to suit your individual needs. Regardless, simply integrating a battery failure mode and effects analysis into your battery design process, battery manufacturing process, and battery sales process is a valuable tool in helping providing the best possible product to customers.

The need for error analysis is captured in the book's arresting cover shot - of the 1895 Paris train disaster (also available as a wall poster). The early chapters teach elementary techniques of error propagation and statistical analysis to enable students to produce successful lab reports. Later chapters treat a number of more advanced mathematical topics, with many examples from mechanics and optics. End-of-chapter problems include many that call for use of calculators or computers, and numerous figures help readers visualize uncertainties using error bars. "Score a hit! ...the book reveals the exceptional skill of the author as lecturer and teacher...a valuable reference work for any student (or instructor) in the sciences and engineering." The Physics Teacher "This is a well written book with good illustrations, index and general bibliography...The book is well suited for engineering and science courses at universities and as a basic reference text for those engineers and scientists in practice." Strain, Journal of the British Society for Strain Measurement
