Provided is an equivalent circuit model of a battery, which is used for simulating an electrochemical impedance spectrum and dynamic charge and discharge characteristics of a battery. The equivalent circuit model comprises an electrical element having a complex parameter. The imaginary part of the complex parameter indicates loss characteristics related to frequency. An inductance element and a capacitor element have complex parameters. The result of the electrochemical impedance spectrum and the dynamic charge and discharge characteristics of a lithium iron phosphate battery that are calculated by using the equivalent circuit model have high accuracy with the error rate less than 5%.
