Power Management Systems with Controllable Adapter Output

摘要

A power management system includes a battery pack (304) having a battery controller (320) and includes an adapter (302) operable for charging the battery pack and powering a system load. The adapter generates a power recognition signal indicative of a maximum adapter power and receives a control signal. The battery controller in the battery pack receives the power recognition signal and generates the control signal to adjust an output power of the adapter according to a status of the battery pack and a status of the system load.
