  • Patent number: 11095135
    Abstract: Dynamic battery discharge at an information handling system during battery charge, such as to support increased power use associated with processor turbo mode, is managed by setting a reduced maximum charge current dynamically during constant voltage charging so that battery voltage droop from discharge does not result in command of an excessive charge current after the discharge.

  • Patent number: 11088565
    Abstract: Techniques for power source management in an information handling system (IHS) include detecting connection of multiple power sources to the IHS through respective DC adapters, obtaining data indicating the capabilities of each power source, obtaining data indicating a system load for the IHS, and generating, based on the obtained data, a load management plan specifying a target combined input power amount for power supplied by the multiple power sources and respective amounts of electrical power to be supplied by a single selected power source or by multiple selected power sources. The techniques also include combining the power supplied by each of the selected power sources into a combined input power and supplying the combined input power to the IHS. Prior to the combining, the voltage of the power supplied by a power source may be stepped up or down to a common voltage, or a power source may be de-rated.

  • Patent number: 10963359
    Abstract: An information handling system (IHS) includes a battery management unit (BMU) and an embedded controller (EC). The EC is operable for detecting a trigger for monitoring power consumption in light of a first condition, capturing a state of the IHS, writing data representing the state to a power profile log, annotating the log with an identifier of a point at which logging associated with the first condition begins, obtaining, from the BMU, power data representing an amount of current flowing from or charge delivered by a battery, writing at least some power data to the log, detecting a trigger for ending monitoring associated with the first condition, annotating the log with an identifier of a point at which logging associated with the first condition ends, and generating, dependent on the annotations of the identifiers in the log, a power profile report indicating power consumption associated with the first condition.

  • Patent number: 10673271
    Abstract: A power adapter device may use a method for efficient charging of multiple portable information handling systems based on learned charging characteristics. In particular, when electrical power is delivered to at least one of the portable information handling systems, the power adapter device may prioritize electrical power delivery to another portable information handling system ahead of the portable information handling systems based on the learned charging characteristics such that charging is efficient.

  • Patent number: 10620679
    Abstract: A power storage adapter (PSA) may be connected to multiple battery-powered devices. A PSA controller may be configured to receive respective requests to supply electrical power to a first device and a second device, to determine that the power storage adapter does not have sufficient power supply capacity to satisfy both requests, to determine that a respective state of charge (SOC) of at least one device battery is below a first battery SOC threshold, and to prioritize supplying electrical power to a selected one of the devices at the expense of the other device based on a battery charging prioritization policy. The selected device may be prioritized until the battery SOC exceeds a battery SOC threshold or for a predetermined time period. The battery charging prioritization policy may specify relative charging priorities for the device batteries and a PSA battery dependent on whether AC line power is available.

  • Publication number: 20200050247
    Abstract: A convertible information handling system in a clamshell configuration provides a maximum housing surface temperature at a predetermined portion, such as a fan exhaust, that is greater than a maximum temperature in a tablet configuration. Upon detection of transition to the tablet configuration, a burst application by a thermal rejection device reduces the temperature at the predetermined portion to aid in achieving the maximum temperature of the tablet configuration. For example, a burst application may include running a fan at full speed for a defined time or decreasing a pressure within a vapor chamber.

  • Patent number: 10488906
    Abstract: A power storage adapter may use a method for power delivery based on temperature and other factors. In particular, when electrical power is being supplied to a portable information handling system, a temperature of the power storage adapter may increase. Power storage adapter may reduce the electrical power being supplied to the portable information handling system based on the temperature to prevent the power storage adapter from potentially overheating.
