Tóm tắt

Performance of lithium-ion batteries is contingent on the operational temperature and applied current rate. Especially in electric vehicle (EV) application, repeated heavy-duty drive cycles impose intense thermal stress on batteries, resulting in safety concerns. This article explains the electrochemistry within the battery and analyzes the dependence of battery internal parameters on temperature and current rate based on their electrochemical nature. In addition, this interdependence is used in the equivalent circuit model to predict the battery behavior under different drive cycles. Finally, the behavior under different drive cycles is analyzed to improve the battery performance in electric vehicles.
