This paper introduces a novel method to identify electrochemical impedance spectrum (EIS) for electric vehicle batteries. The drive inverter generates AC signal required for EIS identification while the motor is operated unaffected. Flexibility and low cost are the biggest advantages. Experiments have verified the effectiveness of this method.
