Abstract
The load profile of the power converter in EV Fast charging applications involves a short high-current pulse for rapid charging of the EV battery leading to thermal cycles on the power electronic devices. These thermal cycles can cause thermo-mechanical fatigues, which consume the power devices’ lifetime. Also, different timescales and magnitude of temperature swings lead to various failure modes. This paper compares different empirical lifetime models quantitatively in order to suggest the most appropriate model to predict the end of life of power electronic devices used in EV fast chargers. It is suggested that the selected model takes into account the most relevant failure mechanism based on the different timescales and magnitude of thermal cycles to indicate the lifetime of power electronic device used in a fast charger depending on the number of charging sessions.
