Communication systems and methods for transmitting communications between a charge system and an AC adapter

摘要

Communications systems and methods for transmitting communications between a charge system and an AC adapter are disclosed. In one embodiment, a communication system comprises an AC adapter disconnect switch that is switchable between coupling and decoupling an AC adapter DC output voltage to the charge system and a charge controller configured to modulate the AC adapter disconnect switch between coupling and decoupling to provide a communication signal to the AC adapter.

1. A communication system for transmitting communications between a charge system and an AC adapter, the communication system comprising:
an AC adapter disconnect switch that is switchable between coupling and decoupling an AC adapter DC output voltage to the charge system; and a charge controller configured to modulate the AC adapter disconnect switch between coupling and decoupling to provide a communication signal to the AC adapter, wherein the communication signal comprises a control signal that instructs the AC adapter to provide manufacturing information as well as one of a desired AC adapter DC output voltage and/or current, enter a sleep mode, exit a sleep mode, and provide an adapter rating.
