3.4.3 Dynamic Accuracy of the LMN Battery Models

Previously, only the error values were used to evaluate the battery model accuracy. In the following, the dynamic accuracy achieved with the introduced battery model , which considers all relevant electrochemical effects, is discussed in detail in terms of relaxation, hysteresis, and temperature influence. The dynamic behavior of the measured cell chemistries is all similar, due to which the resulting plots are depicted for Cell B only. Figure 3.9 shows the temperature validation signal, where SoC and temperature trajectory are depicted in Subplot three and four, respectively.
