Abstract:

An exponential increase in electric vehicles on the road needs a follow-up in terms of the warranty. The proposed state of warranty (SOW) is a meta state that qualitatively describes the warranty fulfillment level of an electric vehicle. All the relevant warranty information is synthesized in single merit while maintaining the level of detail through the qualitative substates. The developed SOW is calculated with a rule-based logic of an expert system that evaluates the quantitative value of three substates: the remaining warranty, the remaining health, and the remaining useful warranty. The SOW provides a synthesized and user-friendly description of the warranty fulfillment state while providing detailed quantitative information on the most relevant features of each of the different maintenance methodologies.
