Design and Implementation of an On-Board Controller-based Odometer for the Estimation of the Lifetime of Power Modules in Hybrid Vehicles

This thesis presents a software implementation and hardware investigation to monitor the wear-out condition of power modules used in traction applications. A new and original stand-alone tool for a real-time analysis and lifetime estimation has been developed dealing with two optimized algorithms, the Rainflow and the thermo-mechanical Stress-Strain analysis. Finally, different solutions and microcontrollers have been analyzed and benchmarked to define the tool with the best performance
