What changed

The United States Patent and Trademark Office (USPTO) has granted patent US12584966B2 to LG Energy Solution, Ltd. for an apparatus and method for managing batteries. The invention focuses on a system that measures battery voltage during charging and resting periods to calculate resistance, generate a state of charge (SOC) profile, and determine summed resistance based on weighted unit sections of the SOC profile.

This patent grant represents a new intellectual property for battery management technology. While it does not impose new regulatory obligations on companies, it signifies innovation in the energy storage sector. Companies involved in battery manufacturing or management systems should be aware of this patented technology, particularly if their products or methods overlap with the described claims.

Abstract

A battery managing apparatus according to an embodiment of the present disclosure includes a measurement unit configured to measure the voltage of a battery that is charged by repeating a charging period and a resting period; and a control unit configured to calculate a resistance corresponding to each of a plurality of resting periods, generate a first profile indicating a correspondence relationship between a state of charge (SOC) and the resistance of the battery, divide an SOC section of the first profile into a plurality of unit sections, and calculate a summed resistance of the battery based on a weight and a reference resistance corresponding to each of the plurality of unit sections.
