Logical battery partitions

摘要

A logical battery partitioning approach is disclosed. In one embodiment, a power management system in a portable computing device having a plurality of subsystems can include: (i) a battery coupled to a plurality of subsystems; (ii) a first battery variable provided to a first subsystem to indicate a characteristic of a first logical battery partition; and (iii) a second battery variable provided to a second subsystem to indicate a characteristic of a second logical battery partition. A battery variable can include an accessibility control, or a percent of battery power available, for example.

主权项

1. A power management system in a portable computing device, the power management system comprising:
a battery having a plurality of logical battery partitions, each logical battery partition providing power to at least one of a plurality of applications of the portable computing device; a first battery variable to indicate a first characteristic of a first logical battery partition of the plurality of logical partitions, the first characteristic indicating an amount of power available to a first application of the plurality of applications; a second battery variable to indicate a second characteristic of a second logical battery partition of the plurality of logical partitions, the second characteristic indicating an amount of power available to a second application of the plurality of applications; and a power management system to adjust the amount of power available to each of the first and second application based upon a first and second priority assigned to the first and second applications, respectively.
