Modular battery energy storage systems (MBESSs) are a promising technology to mitigate the intermittency of renewables. In practice, the batteries in an MBESS have disparities in their remaining useful life (RUL). Hence, the least healthy battery dictates the MBESS lifespan, which has motivated the development of RUL balancing methods. However,

NREL''s battery lifespan researchers are developing tools to diagnose battery health, predict battery degradation, and optimize battery use and energy storage system design.
The aging of batteries is significantly influenced by the charging and discharging rates. During the charging and discharging process, heat in the battery originates from Joule heat, chemical reactions, and phase transitions.
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.
On a system level, battery aging manifests itself in decreasing usable capacity and increasing charge/discharge losses over a BESS lifetime , . This in turn directly affects the economic viability of a BESS, as less profit from the application can be generated in later years compared to the beginning of life , .
The aging of LIBs is affected by multiple factors, making it difficult to predict their lifetime. The nature of battery aging lies in the physico-chemical reactions of various components inside the battery. For example, battery capacity fade is caused by the loss of active lithium and active materials.
A profit of 63.3 kEUR is achieved in year 1 and 36.7 kEUR in year 10. In summary, scaling the aging cost to Q loss,cal = 5 % and Q loss,cyc = 5 % in the scenario investigated here has a beneficial effect on both the cumulative profit from energy arbitrage and its NPV.
The main aging mechanisms of fast charging batteries are lithium plating and loss of active materials. Of course, accelerated aging would be pointless if the battery suffers significant lithium plating and active materials loss .
