ELECTRONIC DEVICE AND POWER ADAPTER CAPABLE OF COMMUNICATING WITH EACH OTHER, AND ASSOCIATED CHARGING SYSTEM

摘要

A charging system (100) includes an electronic device (120) and a power adapter (110) for charging the electronic device (120). The electronic device (120) has a bi-directional communication with the power adapter (110); and the electronic device (120) is arranged to send a health check command to the power adapter (110), and the power adapter (110) performs a self-health check operation and reports a checking result to the electronic device (120). In addition, the electronic device (120) may calculate a cable impedance, and control a compensation function of the power adapter (110) by referring to the calculated cable impedance.
