Learn MoreAbstract: The effectiveness of a battery management system (BMS) in lithium-ion batteries (LIBs) is significantly dependent on the accuracy of battery sensors. However, owing to the highly nonlinear nature of LIBs, detecting small uncertainties in sensor measurements, which can lead to high estimation errors, poses a remarkable challenge.
The SOC estimation model developed for a single lithium-ion cell can be scaled to battery packs, which are composed of many cells connected in series and parallel configurations. However, larger battery packs introduce non-uniformities between individual cells, which can affect SOC accuracy.
Conclusions This study demonstrated that using the Taguchi method and ANOVA for optimizing the HPPC profile significantly improves the accuracy of SOC estimation for lithium-ion batteries.
This represents a more moderate, favourable operating temperature for lithium-ion batteries compared to the previous analysis at −10 °C and, as a result, the SOC estimation performance under these conditions is expected to improve due to more stable electrochemical activity in the cells.
Among the various ECM configurations, the 2-loop model, also known as the 2RC model, is particularly effective in capturing the dynamic behaviour of lithium-ion batteries under different operating conditions. The structure of the 2RC model is depicted in Figure 2. Figure 2. Schematic of the second-order (2RC) equivalent circuit model.
While temperature is recognized as a critical factor affecting lithium-ion battery performance, studies such as those by Tang et al. and Sharma et al. generally focused on low or high temperatures without considering intermediate conditions.
