Tentative Investigation and Semi-Empirical Modeling of Charge Time in Lithium-ion Battery to Control the Charge Process in Different C-Rates %K Lithium-ion battery %K Modeling %K charging time %K C-rate, Charger %K electric vehicle %R %X One of the main challenges in the development of electric vehicles is their long charge time. Therefore, shortening the charge time of a lithium-ion battery (LIB) is a critical issue in this field. The charging process of the LIB is carried out by a constant current-constant voltage charger. The fast charge may affect the performance of LIB and accelerate its degradation. Herein a model is presented which can predict the charge time of LIB accurately in different C-rates so that the coefficient of determination is more than 0.99 in the modeling of five various LIBs. This indicates very good conformity between the experimental results and predictions of the proposed model. Since the constant voltage step in the charging process of the LIB continues as long as the current reduces to a certain value, if the current of this step is not detected correctly, an overcharge will occur. In the case of a perturbation in the LIB system, the current may not drop with a logical procedure, which can lead to an overcharge and capacity loss of LIB. Therefore, it is possible to limit the charge time in both constant current and constant voltage steps by accurate estimation of LIB charge time. This method can prevent further deterioration of LIB during fast charging. %U https://www.nsmsi.ir/article_38048_2bce171b3c5a2145fe0e11fc13ae5ebe.pdf
