  • Publication number: 20230336002
    Abstract: Power management techniques are disclosed. For instance, an apparatus may include a bidirectional voltage converter circuit, and a control module that selectively operates the bidirectional voltage converter circuit in a charging mode and a delivery mode. The charging mode converts a voltage provided by an interface (e.g., a USB interface) into a charging voltage employed by an energy storage module (e.g., a rechargeable battery). Conversely, the delivery mode converts a voltage provided by the energy storage module into a voltage employed by the interface. Other embodiments are described and claimed.

  • Publication number: 20220376623
    Abstract: A computing system having a high-performance battery pack (e.g., 3S, 4S battery packs) coupled to a voltage regulator and logic to control an input supply of the voltage regulator. The logic determines the context of usage of the computing device (or user attentiveness) and either dynamically bypasses the voltage regulator to provide the voltage from the high-performance battery pack directly to various components of the computing system, or dynamically engages devices of the voltage regulator to provide a lower supply voltage to the various components of the computing system.

  • Patent number: 9898025
    Abstract: A method and apparatus to balance adapter power supply and computing device power demand. In one embodiment, power to/from battery pack(s) maybe controlled by adjusting the output voltage of the power adapter via the current input to the power adapter through a feedback pin to meet power demand of electrical loads. Another embodiment provides a way to adjust the activities of the electrical loads such that neither adapter power rating nor the electrical load power limit is exceeded while avoiding system shutdown.

  • Patent number: 9798379
    Abstract: A computer system has a controller and a voltage regulator. The controller generates a power consumption state signal for one or more components of the computer system to the voltage regulator. The voltage regulator supplies a first voltage level for the one or more components when the one or more components are at a first power consumption state. The voltage regulator increases to a second voltage level for the one or more components when the one or more components enter a second power consumption state.
