What is failure modes and effect analysis (FMEA)?
The failure modes and effect analysis (FMEA) method is employed to classify these failures based on priority numbers. By studying 28 accident reports involving electric vehicles, data is collected to identify potential failure modes and evaluate their risks.
How does the FMEA assess potential failure modes involving electric vehicles?
By studying 28 accident reports involving electric vehicles, data is collected to identify potential failure modes and evaluate their risks. The results obtained from the FMEA assessment are used to propose safety measures, considering the importance of the potential failure modes as indicated by their risk priority number (RPN).
What does FMEA stand for?
An FMEA (Failure Modes, and Effects Analysis) has been undertaken to assess the modes of failure of the battery for the laboratory testing of these systems. It is an approach that can be used to inform possible solutions to the most likely failures . The FMEA was performed on the system shown in Fig. 2, Fig. 3 and can be found in Appendix. 4.
How can FMMEA improve battery design & simulation?
FMMEA-enhanced design and simulation tools can enable battery manufacturers to rapidly develop new batteries by assessing the impact of chemistry and design on performance and safety. Battery system designers will also benefit from life cycle simulation capabilities that include models for all relevant failure mechanisms.
How does FMEA work?
When carrying out the FMEA, experts identify failures throughout the process chain and then try to graphically depict their CERs, which ultimately results in the failure net. After that, experts need to conduct the actual rating of the identified failure CERs in terms of their severity, probability of occurrence and detectability.
What is design failure mode and effect analysis (DFMEA)?
Design failure mode and effect analysis (DFMEA) focuses on potential failure modes that are caused by the specifications and design parameters finalized in the design phase. While designing a lithium-ion battery, the general requirements for lithium-ion battery abuse tolerance also need to be considered .
