| description | PROBLEM TO BE SOLVED: To provide a secondary battery state diagnostic method, configured to accurately diagnose a state of a secondary battery mounted on a vehicle on the basis of a measured impedance value, and to identify where a fault has occurred in the secondary battery.SOLUTION: A state diagnostic method of a secondary battery 10 comprises the steps of: preparing an equivalent circuit model based on a configuration of the secondary battery 10 (STEP-100); calculating a theoretical characteristic value of the secondary battery 10 from the prepared equivalent circuit model (STEP-100); measuring impedance Z of the secondary battery 10 (STEP-101); calculating an actual characteristic value of the secondary battery 10 from the impedance Z of the secondary battery 10 (STEP-102 to STEP-104); and comparing the actual characteristic value with the theoretical characteristic value to diagnose the state of the secondary battery 10 (STEP-105 and STEP-106). |
