Abstract: An information handling system stores a knob table, and determines time series data for one or more applications being executed. The information handling system extracts features associated with the system, and determines a system type for the information handling system. The system determines a running average power level based on the time series data, the extracted features, and the system type. Based on the determined running average power level, the information handling system determines a configuration knob to optimize the system. The configuration knob is determined from the knob table in the memory.

Abstract: Systems and methods are provided that may be implemented to automatically and intelligently re-activate battery cell/s of a battery system after the battery system has been subjected to relatively long term storage with the battery system inactive and unpowered by external power. The disclosed systems and methods may be so automatically implemented once external power is provided to the battery system and the battery system becomes active again. In one example, the disclosed systems and methods may be implemented on a battery-powered information handling system using logic executing on a programmable integrated circuit of a battery system (e.g., battery management unit “BMU”) of the information handling system and/or at the system level (e.g., such as embedded controller “EC”) of the information handling system.

Abstract: A system can comprise a shell, one or more battery cells disposed within the shell, and a pressure-directing layer disposed between the battery cell(s) and the shell's interior surface. Each of the battery cell(s) can comprise an enclosure including a gas-impermeable portion and a venting portion configured to permit gas to exit the enclosure. The pressure-directing layer can comprise one or more openings that each overlie the venting portion of the enclosure of at least one of the battery cell(s). In some systems, the pressure-directing layer can have a thickness that is less than a distance between the battery cell(s) and the interior surface of the shell such that there is a space between the battery cell(s) and the interior surface of the shell. In some systems, the pressure-directing layer can be coupled to the battery cell(s) and the interior surface of the shell and comprise a resilient material.

The EC sends a request to the processor based upon a temperature of the battery system. The request includes power limit recommendation that is received by the processor. The processor adjusts a workload based upon the received power limit recommendation from the EC. The adjustment in the workload may correspond to a decrease in discharging rates of the battery system.

Abstract: The disclosure discloses a method for preparing a high-reflection solar cell backsheet film, which uses a twin-screw extruder to prepare a masterbatch of an adhesive layer, a masterbatch of a barrier layer, and a masterbatch of a high-reflection layer, and then uses four single-screw extruders to melt the three masterbatches at 250° C. and extrude through a lip film of a casting head. A non-woven fabric is added as a base layer between the two barrier layers, so that the two barrier layers are extruded through the lip film and integrally formed on surfaces of the non-woven fabric. After being cooled to room temperature by a cooling roller, a highly reflective solar cell backsheet is obtained.
