Abstract: A computer-implemented method of diagnosing one or more SoXs, such as State-of-Charge (SoC), State-of-Health (SoH), State-of-Energy (SoE), State-of-Power (SoP), State-of-Function (SoF) and State-of-Safety (SoS), of at least one battery, comprises a SoX diagnostics loop, which includes a given battery model, and a model update loop, which is configured to update the battery model, the method comprising: receiving, by the SoX diagnostics loop from at least one sensor, at least one measured battery parameter of the battery, determining, by the SoX diagnostics loop, at least one SoX descriptor of the battery using at least one of the following: at least one SoX parameter, at least one comparison of the at least one SoX parameter: to its previous value, to the at least one another SoX parameter, to the at least one threshold value, wherein the at least one SoX parameter is one of the following: the at least one measured battery parameter, at least one simulated battery parameter provided by the battery model, t

Abstract: A method for modeling, simulating, or emulating a battery may include generating an equivalent electric circuit model of a battery. The equivalent electric circuit model may include models of the battery's cathode and anode. At least one of the models of the cathode and anode may comprise one or more sub-circuit models. A sub-circuit model may comprise a first current inlet, a second current inlet, at least one voltage source, one or more resistors, and a capacitance. A first current path may be arranged between the first current inlet and the second current inlet. The at least one voltage source and the one or more resistors may be arranged in series in the first current path. A second current path may be arranged in parallel to the first current path between the first current inlet and the second current inlet. The capacitance may be arranged in the second current path.
