Systems and methods for estimating battery degradation of a battery energy storage system (BESS) are disclosed. An iterative process is executed over a pre-defined time period divided into iterations. For each iteration, an average temperature of the BESS is determined by inputting a state of health (SOH) and charge rate into an average temperature look-up-table (LUT). The SOH for the next iteration is determined by inputting the determined average temperature into a set of cell degradation equations. The charge rate for the next iteration is derived from a usage profile which defines the charging and discharging cycles over the pre-defined time period and includes power and SOC over the pre-defined time period. The SOH of the BESS over the pre-defined time period may then be displayed on a user interface.

Resumen de: US20260061385A1
When producing lithium sulfide by a reaction between a lithium raw material and hydrogen sulfide, the reaction is performed under relatively mild conditions compared to the conventional technology, so frequent repairs or replacements due to corrosion and breakdown of reactors and piping are not required, thereby improving the economic efficiency of the process. Since unreacted hydrogen sulfide and a solvent from which moisture has been removed are reused, process costs are reduced so that economic feasibility in mass production is ensured. Furthermore, moisture and water vapor generated in a lithium sulfide production reaction are effectively removed to prevent a reverse reaction into lithium hydroxide and promote a forward reaction so that high-quality lithium sulfide can be produced with high purity and high yield. In addition, particle size may be controlled in the micrometer range without a separate crushing space or crushing stage, thereby providing excellent convenience and mass production.
