  • Patent number: 12222792
    Abstract: Systems and methods are provided that may be implemented to dynamically change the solid state drive (SSD) power and peripheral component interconnect express (PCIe) link state transition time for solid state drive for SSD operation based on current remaining battery power capacity during a battery-only power mode of an information handling system. In one example, an intelligent algorithm in software and SSD firmware may be implemented that will dynamically change the SSD power and PCIe link state transition based on current remaining battery power capacity during battery-only power mode of an information handling system. In this way additional power saving may be realized when current remaining battery power capacity is low during a battery-only power mode so as to extend the battery life for an information handling system.

  • Patent number: 12113378
    Abstract: A battery system with a large-format Li-ion battery powers attached equipment by discharging battery cells distributed among a plurality of battery packs. The discharging of the battery cells is controlled in an efficient manner while preserving the expected life of the Li-ion battery cells. Each battery pack internally supports a battery management system and may have identical components, thus supporting an architecture that easily scales to higher power/energy. Battery packs may be added or removed without intervention with a user, where one of battery packs serves as a master battery pack and the remaining battery packs serve as slave battery packs. When the master battery pack is removed, one of the slave battery packs becomes the master battery pack. Charging and discharging of the battery cells is coordinated by the master battery pack with the slave battery packs over a communication channel such as a controller area network (CAN) bus.

  • Patent number: 11880575
    Abstract: An information handling system includes a host controller, a memory device, and a processor. The memory device receives I/O commands from the host controller. The memory device includes a processor. The processor sets an initial idle time prior to transition (ITPT) setting as a current ITPT setting for a memory device of an information handling system, and monitors input/output (I/O) commands from a host in the information handling system. While monitoring the I/O commands, the processor increases a first counter in response to the memory device entering a non-operational mode based on the current ITPT setting, and increases a second counter in response to the memory device entering an operational mode within a particular amount of time from when the memory device entered the non-operational mode. The processor further varies the current ITPT setting based on a current ratio of the second counter to the first counter.
