AbstractIn the context of new forms of mobility, knowledge of battery health is a major factor in the electric vehicle ecosystem. Future regulations will impose new health status criteria on automakers, to guarantee controlled ageing at the end of a kilometre and time threshold. The aim of this thesis is to accurately estimate and predict these health criteria using telemetry data from vehicles on the road. Advanced numerical approaches (multiphysics domain, multifrequency, AI on BigData...) will be used during the modeling phases. The predicted states of health will be validated by on-board diagnostics on different vehicles.
