Abstract Although secondary batteries, called rechargeable batteries, are very important energy elements in modern society, their application is hindered by the typical nonlinear and irreversible characteristics. Precise monitoring of the state of health (SOH) for each battery cell on line is crucial for stable operation and proper management of them. This paper proposes diagnostic method of the SOH for a battery cell on line without interruption on its operation nor bad effect on its life. This paper practically diagnoses on 120 industrial batteries and provides some guide lines to decide whether to exchange or not.
