What changed

The United States Patent and Trademark Office (USPTO) has granted patent US12587958B2 to Huawei Technologies Co., Ltd. for an electric energy control method and related device. The patent details a system that manages energy storage and power supply to a main device. It includes mechanisms for charging an energy storage device when main device power is low, and for the main device to receive power from both the power supply and the storage device when power is high. A key feature is the notification to the main device to decrease radio frequency power if the energy storage device's capacity becomes insufficient, thereby preventing potential breakdowns.

This patent grant is primarily an intellectual property matter and does not impose new regulatory obligations on companies. However, it signifies innovation in energy management systems, particularly relevant for companies involved in power supply, energy storage, and device power management. Compliance officers in the technology sector should be aware of this patent as it relates to potential intellectual property landscapes and may inform R&D strategies.

Abstract

This application disclose example electric energy control methods. When power of a main device is lower than baseline power, an energy storage device is in a charging state and stores remaining electric energy. When power of a main device is greater than the baseline power, the main device receives electric energy output by a power supply device and the energy storage device. To be specific, the energy storage device is in a discharging state and supplies power together with the power supply device to ensure operation of the main device. However, an amount of electric energy stored in the energy storage device is limited. When an amount of the electric energy of the energy storage device is insufficient, the main device is notified to decrease radio frequency power of a preset frequency band of the main device, to reduce a breakdown caused by excessively high power of the main device.
