Abstract
In this paper, the reliability analysis of wireless power transfer system for charging electric vehicles using Markov process is presented. Since wireless chargers of electric vehicles are supposed to be exposed to various weather conditions that affect the performance and aging of the system; therefore, reliability analysis of this type of system is required. The reliability analysis of wireless power transfer systems for charging electric vehicles is missing in the literature. Every wireless charger for electric vehicles is composed of five different sub-systems, including a full bridge single-phase inverter, a compensation network in both input and output sides, an inductive coil, and a rectifier. The five sub-systems are analyzed on individual reliability separately, to determine the overall system reliability. The result found have identified the system as highly reliable over twenty years of lifetime with having 66.31% percent availability.
