4 Detailed enlargement of the marked region in Fig. 3 including the current constraints applied in the optimization obtained optimal excitation signal with the recorded voltage response of battery cell B. The current signal and current constraints are depicted in Subplot two, where currents with more than 100 A can be observed. 5C. Nevertheless, the corresponding voltage responses for the two depicted temperatures (see Subplot one) and the SoC (see Subplot three) keep the constraints. Note that even though the constraints of voltage and SoC are indirectly considered, any constraints are met, and the entire relevant range of the SoC is covered.

The second term in Eq. 17) is obtained by the single derivatives of the parameter sensitivity vectors with respect to the model input, which are based on the derivative of the regressor ϕ(k, θ ) as defined in Eq. 1) with respect to the input U (r ). Denoting the derivative of ϕ(k, θ ) by d yˆ (k − n, θ) d yˆ (k − 1, θ) dϕ T (k, θ) = ...
