A method for determining a remaining useful lifetime of a propulsion battery of a vehicle. The method includes constructing a voltage feature vector from voltage data of a charging event for the battery, mapping the voltage feature vector to a battery state of health model including an aging mode distribution of different battery aging mechanisms to determine state of health parameters and the present aging mode distribution of the battery; predicting the remaining useful lifetime (RUL) using a physical aging model with the state of health parameters and the present aging mode distribution as inputs to the physical aging model.
