The present application describes power management devices, systems and methods. In an embodiment, a power management controller is configured to: determine that a secondary electronic device requires an amount of power that exceeds a default power threshold defined in a default power scheme; monitor internal power requirements associated with on-board functions of an electronic device and determine that internal power requirements satisfy predetermined criteria; and in response to determining that the secondary electronic device requires an amount of power that exceeds the default power threshold and that the internal power requirements satisfy the predetermined criteria, adjust a power scheme associated with the port and implemented by the power limiter to provide, to the secondary electronic device, an amount of power that exceeds the default power threshold.

Management of power delivered over a port

A device, system and method for charging a battery are provided. The device comprises: a USB (Universal Serial Bus) port; a battery in communication with the USB port; and, circuitry in communication with the USB port and the battery, the circuitry configured to: transmit a power control signal over the USB port, the power control signal comprising data indicative of one or more of a power, a voltage and a current to be received over the USB port to charge the battery; and, responsively receive the power for charging the battery over the USB port.
