How stable is the OCV-SoC curve of lithium-ion batteries?
While the OCV-SOC curve of lithium-ion batteries is relatively stable, it will change according to the charging/discharging rate, battery temperature, cell variation, and cycle life of the battery, and so on [1, 31]. S. Panchal has studied EV battery system four drive cycle actual conditions at various ambient temperatures.
What is a lithium battery OCV curve?
The OCV of a battery cell is the potential difference between the positive and negative terminals when no current flows and the cell is at rest. The potential difference between the anode and cathode changes based on the ion concentration and hence versus State of Charge (SOC). The typical lithium battery OCV curves versus SoC then looks like:
What is the OCV of a battery?
The OCV of a battery is the voltage when it is under no load (i.e., when no current is flowing in or out of it). This OCV voltage is directly related to the SOC of the battery. The various steps involved in the OCV-SOC method are shown in Fig. 2. Systematic flow diagram of the OCV-SOC method
