7. Conclusions The application of the Preisach model originally used in the magnetic material hysteresis characterisation to lithium-iron-phosphate (LFP) batteries, which show experimental evidence of a hysteretic behaviour between state-of-charge (SoC) and open-circuit voltage (OCV), is described in this paper.
Provided by the Springer Nature SharedIt content-sharing initiative The open circuit voltage hysteresis of lithium-ion batteries is a phenomenon that, despite intensive research, is still not fully understood. However, it must be taken into account for accurate state-of-charge estimation in battery management systems.
The relaxation time for the OCV measurement is 1 h. Hysteresis in lithium-ion (Li-ion) batteries can be ascribed to thermodynamic entropic effects, mechanical stresses, and microscopic distortions within the active electrode materials during lithium insertion or extraction .
To accurately estimate the SOC of LiFePO 4 batteries, a hysteresis voltage reconstruction model is developed to analyze the hysteresis characteristics of LiFePO 4 batteries under automotive dynamic conditions and energy storage frequency regulation conditions.
LiFePO 4 batteries demonstrate differences in open circuit voltage (OCV) under different charge and discharge paths, indicating the hysteresis phenomenon of OCV, which is more evident under energy storage frequency regulation conditions.
Additionally, LFP batteries exhibit open-circuit voltage (OCV) hysteresis, wherein the OCV is closely related to the historical path of charge and discharge. Consequently, the operating conditions in the energy storage scenario impact the accuracy of the model terminal voltage.
