One of the methods includes obtaining temperature data, for one or more locations within or on the surface of a battery, the temperature data comprising time-varying heat flow inputs applied to the battery and time-varying tem- perature signals generated by the battery. The method also includes processing the temperature data to generate a continuous-time thermal model having one or more time-delay elements and one or more parameters, wherein parameter values are fitted using the temperature data.
