*3.2. Parametrization*

The model was parameterized by Constant-Current Constant-Voltage (CCCV) measurements to estimate the cell's capacity. With a constant current of 1C until *U*Cell = 4.2 V for charging, respectively *U*Cell = 2.8 V for discharging. The voltage was kept constant until the cell current reached *I*Cell < 1/20C. The serial resistor and the parameters of the RC-pairs were determined by 2C charge and discharge current pulses at 34 different SoCs. The cells were relaxed one hour after each pulse to estimate the OCV and guarantee same start conditions for each pulse. The measurements were repeated at different cell temperatures (The current pulses were reduced to *I*Cell = 0.2C at cell temperatures *T*Cell < 10 ◦C in order to keep the cells in their operating window.) *T* = 0, 5, 10, 20, 30 and 40 ◦C. The parametrization process as well as the results of the ECM parameters are presented in more detail in previous work [2].
