What changed

The United States Patent and Trademark Office (USPTO) has granted patent US12587007B2 to Volvo Truck Corporation for a method and system designed to control overcurrent fuses within a vehicle's battery pack energy storage system. The patented technology involves a computer system that monitors individual battery pack currents and the total system current, comparing them against predetermined thresholds. It is designed to activate fuses for specific battery packs or the entire system when overcurrent conditions are detected, thereby enhancing electrical safety and system integrity.

This patent grant is primarily relevant to manufacturers and product developers in the automotive and energy storage sectors. While it does not impose direct compliance obligations on other entities, it represents a technological advancement in battery management systems. Companies involved in electric vehicle design, battery manufacturing, or power electronics may need to be aware of this patented technology to avoid potential infringement issues or to inform their own research and development efforts.

Abstract

A computer system includes a processor device configured to determine battery current of each battery pack of a plurality of parallelly connected battery packs of an energy storage system of a vehicle, determine a system current for all of the plurality of parallelly connected battery packs in the energy storage system, compare the determined battery current with a predetermined battery pack overcurrent threshold for each one of the battery packs, and comparing the determined system current with a system overcurrent threshold, activate an overcurrent fuse of an associated battery pack in response to the determined battery current of the associated battery pack being higher than the battery pack overcurrent threshold, and to activate the overcurrent fuse of at least one of the same battery packs in response to the determined system current being higher than the system overcurrent threshold.
