Hysteresis is a phenomenon where an output lags behind its input when the system changes direction. In battery systems, this is most commonly seen after charging when the open circuit voltage is different compared to the OCV after discharging to the same SoC. It can significantly impact the accuracy of an SoC estimation algorithm and, therefore, the entire system's performance.
