To achieve the aims of reducing energy consumption and CO2 emissions, Fully Electric Vehicles (FEVs) need to reach a significant market share. However, the advent of FEVs in mass production presents new challenges to automotive manufacturers due to the relative immaturity of the new building blocks, which may impact on the FEV's safety and reliability. Among the most important of these is the electric powertrain: i.e. electric traction motors and their power electronics controllers. This paper presents the FP7 project HEMIS. One of the main aims of this project is to design an in-vehicle Prognostic Health Monitoring System (PHMS) for the powertrain in order to enhance safety and maintainability. The article presents the architecture proposed for a generic FEV and its electric powertrain. The results of a RAMS analysis undertaken to assess the use of the PHMS are also summarised.
