Summary

The USPTO has granted Hyundai Motor Company a patent for an apparatus and method to correct battery cell voltage. The patent, US12584967B2, details a system that measures battery cell voltages and adjusts them based on preset discharge currents and thresholds. This grant signifies a new intellectual property development in battery technology.

What changed

The United States Patent and Trademark Office (USPTO) has granted Hyundai Motor Company patent US12584967B2 for an "Apparatus for correcting voltage of battery cell and method thereof." The patent describes a system that includes a voltage sensor and a controller designed to measure voltages of multiple battery cells, identify target cells based on preset discharge currents and voltage change thresholds, and then correct these voltages. The filing date for this application was December 8, 2023.

This patent grant represents a new piece of intellectual property for Hyundai in the battery technology space. While patent grants themselves do not impose new regulatory obligations on other entities, they can influence industry standards and competitive landscapes. Companies involved in battery manufacturing or electric vehicle development, particularly those utilizing similar voltage correction mechanisms, should be aware of this granted patent as it may impact their own intellectual property strategies and potential licensing requirements.

Abstract

In an apparatus for correcting a voltage of a battery cell and a method thereof. The apparatus includes a voltage sensor configured for measuring voltages of a plurality of battery cells, and a controller which is configured for determining an amount of voltage change of each battery cell corresponding to a preset discharge current, detects target battery cells whose identification numbers have preset intervals while the amount of voltage change does not exceed a threshold value, and corrects the amount of voltage change of each target battery cell.
