    Abstract: A battery pack for an information handling system includes a battery cell configured to provide current to the information handling system, and a battery management unit including an output to the information handling system. The output provides a maximum continuous current (MCC) indication and a peak power (PP) indication. The battery management unit determines an amount of current that the battery cell provides to the information handling system and determines an optimum MCC value that the battery cell can provide to the information handling system. The battery management unit further provides a first value on the PP indication, the first value being greater than the optimum MCC value, sums the amount of current provided to the information handling system that is in excess of the optimum MCC value, determines that the sum is greater than a threshold, and provides a second value on the PP indication, the second value being less than the optimum MCC value.

  • Patent number: 11357128
    Abstract: A heat dissipation system with air sensation function includes a chassis, multiple fans, multiple air sensation units and an external control device connected to the fans. The chassis has an installation face for installing the fans thereon. The air sensation units are respectively disposed on the fans for detecting the air state of the corresponding fans to generate an air sensation signal. The external control device serves to receive the air sensation signal transmitted from the air sensation units and compare the data contained in the air sensation signal with preset data so as to control/adjust the rotational speed of the corresponding fans. Accordingly, a uniform airflow flows out of the fans to effectively lower the noise.

  • Patent number: 11326624
    Abstract: A fan noise-lowering structure includes a fan frame main body and a connecting pipe. The fan frame main body has a bottom section and a peripheral wall section; the peripheral wall section is externally located around and forwardly extended normal to the bottom section and internally defines an air-stream passage. Further, the peripheral wall section is formed with a first pipe and a second pipe, which are communicable with the air-stream passage defined in the peripheral wall section. The connecting pipe has two ends respectively connected to the first pipe and the second pipe. With the connecting pipe, air at an air outlet of the air-stream passage having higher pressure is guided to generate swirls, which moves toward an air inlet of the air-stream passage to thereby effectively lower the noise produced by the fan in operating.
