Method and system for sampling multiple profiles in a charging port without host intervention

摘要

An emulation system for charging any arbitrary portable device through a communication port on the portable device. The system includes a receptacle port for communicating with the portable device and a profile database for storing multiple charging profiles. Each charging profile including a set of parameters and at least one exit condition. Further, an emulation module applies a first charging profile to the portable device and monitors the set of parameters associated with the charging profile to identify an associated exit condition. Upon a determination that the exit condition for the first charging profile is met, the emulation module applies a next charging profile to the portable device.

1. A system for charging a portable device through a communication port on the portable device, the system comprising:
a receptacle port for communicating with the portable device wherein the portable device does not provide charging protocol information to the system; a profile database for storing multiple charging profiles, each charging profile including a set of parameters and at least one exit condition; and an emulation module configured to perform: selecting a first charging profile from the profile database wherein the first charging profile is predefined; applying the first charging profile to the portable device; monitoring the set of parameters associated with the charging profile to identify an associated exit condition; and applying a next charging profile to the portable device upon a determination that the exit condition for the first charging profile is met.
