A database containing data from hundreds of abuse tests conducted on commercial lithium–ion batteries has also been released by NREL [180, 181]. After reviewing the existing literature on a battery technology, data generation should take into account the cost and time constraints of the experiments.
The lithium-ion battery modeling plays a crucial role in the analysis and control of electric vehicle power systems. To improve the accuracy, robustness and rapidity of lithium-ion battery models, many scholars have conducted relevant research and exploration.
In order to use lithium-ion batteries safely and effectively, an accurate and low-complexity model is needed to describe the dynamic and static characteristics inside the battery .
Some examples are hydrogen-based technologies, sodium–ion batteries, lithium–ion capacitors or aqueous ammonium–ion batteries [2, 3, 4]. Lithium–ion batteries are the most widely used and represent the cornerstone of two growing markets: renewable energy and electric mobility .
