The open-circuit voltage (OCV) curve is the voltage of a battery as a function of the state of charge when no external current is flowing and all chemical reactions inside of the battery are relaxed. Each battery chemistry and cell type have an individual OCV curve based on its inner state, which is why the OCV curve can be compared to a fingerprint.
