Abstract:
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for the generation and use of a fast battery model. 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 temperature 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.
