Abstract

The utilization of batteries in electric vehicles is inseparable from the potential danger. The batteries, as the most important part of electric vehicles, must have a highly reliable safety system so it will be safe for the users. In order to produce such a highly reliable safety system in electric vehicles, depth analysis of the possible failures of the battery is carried out. This paper discusses the potential failure modes and potential failure effects, evaluates the causes, and calculates the risks to classify the failures based on priority number using FMEA method (Failure Modes and Effect Analysis method). From the result of the FMEA assessment, the safety action is recommended based on the RPN value of the potential failure mode.
