MUMBAI, India, June 19 -- Intellectual Property India has published a patent application (202617059066 A) filed by Lg Energy Solution, Ltd. on May 08, 2026, for Systems And Methods For Determining Degradation Of Batteries.
Inventors include Pointer, Marielle; and Kumar, Kiran.
The application for the patent was published on June 05, 2026, under issue no. 23/2026.
Abstract: 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.
