  • 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.

  • Publication number: 20210232196
    Abstract: Systems and methods are provided for adaptively powering an Information Handling System (IHS) using a multimode AC adapter. Information reported by the multimode adapter is utilized to determine whether it supports USB-PD power transmissions and also supports high-power transmissions. The power demand of the IHS is monitored. When the power demand is greater than the USB-PD power levels, the multimode adapter is configured for providing a high-power transmission and a power circuit of the IHS is configured for converting the high-power transmission to a voltage used by the IHS. When the power demand is not greater than the USB-PD power levels, the multimode adapter is configured for providing a USB-PD transmission. Some embodiments may detect events associated with high power demand and may preemptively configure the power circuit of the IHS for providing high-power outputs upon detecting such events.

  • Publication number: 20210232193
    Abstract: Systems and methods are provided for powering an Information Handling System (IHS). The system includes a multimode AC adapter that reports supported outputs, including USB-PD (Universal Serial Bus Power Delivery) outputs and also including high-power outputs of a voltage greater than the USB-PD output voltages. The IHS detects a coupling of the multimode AC adapter to a USB-C port of the IHS. Based on information provided by the multimode adapter, the IHS determines the multimode adapter supports transmission of the high-power outputs to the USB-C port. The high-power outputs are negotiated and a power circuit of the IHS is configured for converting the negotiated high-power output. The configured power circuit converts the negotiated high-power output received via the USB-C port to an input utilized by the IHS. The high-power conversion circuit may provide efficient conversion of input voltages of up to 60 volts to voltages for use by the IHS.

  • Publication number: 20210232526
    Abstract: Multimode docking station embodiments provide power to an Information Handling System (IHS). The docking station detects the coupling of a multimode USB-C adapter that supports USB-PD (USB Power Delivery) transmissions and also supports a high-power transmission of a voltage greater than the USB-PD transmissions. The docking station configures a power transmission by the multimode USB-C adapter based on a power request by the IHS. Based on the power request by the IHS, a power circuit of the docking station is configured for providing the transmission to the IHS. When the multimode adapter provides a USB-PD power transmission, the power circuit routes the transmission directly to the docking port. When a high-power transmission is provided, a portion of the power transmission is converted by the power circuit for use by external devices coupled to the docking station, with another portion being provided to the IHS as a USB-PD transmission.

  • Publication number: 20210234393
    Abstract: Systems and methods are provided for charging a battery system of an Information Handling System (IHS) using a multimode AC adapter. Information reported by the multimode adapter is used to determine its capabilities, including whether it supports USB-PD transmission and also supports high-power transmissions of a voltage greater than the USB-PD voltages. The charge state of the battery system is monitored. When the battery is in a pre-charge state, the battery is charged using USB-PD transmissions negotiated with the multimode adapter. When the battery is in a bulk-charge state, the battery is charged using a high-power transmission negotiated with the multimode adapter. When the battery is in a top-off-charge state, the battery is charged using USB-PD transmissions negotiated with the multimode adapter. In light of the charging efficiency of a battery varying based on its charge level, the multimode adapter supports efficient charging at different charge levels.

  • Publication number: 20210232202
    Abstract: Systems and methods are provided for powering an Information Handling System (IHS) that receives a high-power transmission from a multimode AC adapter supporting USB-PD transmission and also supporting the high-power transmissions of a voltage greater than the supported USB-PD voltages. A power circuit converts the high-power transmission to a charging voltage used to charge a battery system of the IHS. After the multimode AC adapter is unplugged from the IHS, power is drawing power from the battery system of the IHS. When the battery system drops below a low-voltage threshold, the power drawn from the battery system is routed to the same power circuit. While operating this low-voltage threshold, power is drawn from the battery system via the power circuit. When the battery system drops below a second low-voltage threshold, an off power state of the IHS is initiated.

  • Publication number: 20210234402
    Abstract: Systems and methods provide wireless power to an Information Handling System (IHS). A multimode wireless power transmission unit supports USB-PD (Universal Serial Bus Power Delivery) power transmissions and also supports a high-power transmission of a voltage greater than USB-PD transmission voltages. The IHS detects the wireless coupling of the wireless power transmission unit. As part of this coupling, the IHS determines whether the wireless power transmission unit supports high-power transmissions. A wireless power transfer is negotiated and a power circuit of the IHS is configured for converting the negotiated high-power transmission to an input utilized by the IHS. Embodiments utilize a power circuit that provides efficient conversion of power transmissions of up to 60 volts. This same power circuit also provides efficient conversion of power transmissions of up to 60 volts by a multimode USB-C power adapter.
