2016年11月1日 · A state-of-charge (SOC) versus open-circuit-voltage (OCV) model developed for batteries should preferably be simple, especially for real-time SOC estimation. It should also be capable of representing different types of lithium-ion batteries (LIBs), regardless of temperature change and battery degradation.

2024年5月17日 · Advanced lithium-based batteries, such as lithium-iron-phosphate (LiFePO 4) and LTO are among the safest and most durable currently available battery energy storage technologies, characterized by exceptional thermal stability and long cycle life (Zhang et al. 2018).

The Open Circuit Voltage (OCV) is a fundamental parameter of the cell. 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 typical lithium battery OCV curves versus SoC then looks like:

Open-Circuit-Voltage (OCV) data is widely used for characterizing battery properties under different conditions. It contains important information that can help to identify battery state-of-charge (SOC) and state-of-health (SOH).
