Three typical benchmark methods are introduced and validated on a commercial Li-ion battery. The effect of SOC, C-rate and current direction on parameters variation are discussed. The performance of the three methods is validated on HPPC and three different cycles.
Developing algorithms for battery management systems (BMS) involves defining requirements, implementing algorithms, and validating them, which is a complex process. The performance of BMS algorithms is influenced by constraints related to hardware, data storage, calibration processes during development and use, and costs.
Thus, model-based estimation has been proposed to estimate the battery SOC and SOH with high fidelity [26, 27]. It is more suitable for online implementation in a BMS, and its accuracy is highly related to the precision of the battery model .
Offline parameter identification can utilize a predefined test profile to fully excite the battery, and high-precision lab facilities can be chosen to measure the battery's current and voltage. Thus, the parameters obtained offline could be used as a benchmark for parameterizing the battery ECM.
In addition, no comparison methods and discussions have existed in the above studies. The publications in Scopus are investigated between 2012 and 2022 with the item “battery parameter identification”. It is generally acknowledged that battery parameter identification is critical to state estimation and EV applications.
Off-road applications as in aviation, the underwater and marine sector together with stationary grid scale and microgrid storages are further applications for battery algorithms. Furthermore, second-life applications of vehicle LIBs and vehicle grid integration are interfaces between automotive and other sectors.
