A case study reveals the most relevant aging stress factors for key applications. The amount of deployed battery energy storage systems (BESS) has been increasing steadily in recent years.
The amount of deployed battery energy storage systems (BESS) has been increasing steadily in recent years. For newly commissioned systems, lithium-ion batteries have emerged as the most frequently used technology due to their decreasing cost, high efficiency, and high cycle life.
As the simulation continues the model demonstrates that around the 370th cycle the nonlinear degradation occurs. These results are significant as they demonstrate how a physics-based ageing model parameterized for CC cycling can validate and forecast battery ageing for a dynamic power profile with nonlinear capacity fade.
Parameters varied include temperature (T), storage State of Charge (SoC), SoC window and Depth of Discharge (DoD), charge (C c), discharge rate (C d), general current rate (C c/d), charging protocol (CP), pressure (p), and check-up interval (CU). Table 1 Overview of comprehensive battery aging datasets.
Accelerated aging, as an efficient and economical method, can output sufficient cycling information in short time, which enables a rapid prediction of the lifetime of LIBs under various working stresses. Nevertheless, the prerequisite for accelerated aging-based battery lifetime prediction is the consistency of aging mechanisms.
