Method of power management, portable system and portable power bank

摘要

A method of power management is to be implemented by a portable electronic device coupled to a portable power bank. The portable power bank is further coupled to an electrical appliance. In the method, the portable electronic device receives power information from the portable power bank, and controls the portable power bank to operate in one of a first mode, in which electrical power is provided to the electrical appliance, and a second mode, in which electrical power is not provided to the electrical appliance, based on whether or not the portable power bank has sufficient amount of power.

主权项

1. A portable system capable of providing electric power to an electrical appliance, said portable system comprising:
a portable electronic device; and a portable power bank coupled to said portable electronic device and to be further coupled to the electrical appliance; wherein said portable electronic device is configured to
receive power information from said portable power bank,control said portable power bank to operate in a first mode, in which electrical power is provided to the electrical appliance, when said portable electronic device determines from the power information that said portable power bank has sufficient amount of power, andcontrol said portable power bank to operate in a second mode, in which electrical power is not provided to the electrical appliance, when said portable electronic device determines from the power information that said portable power bank does not have sufficient amount of power, wherein said portable power bank includes:
a rechargeable battery;an information acquiring module coupled to said rechargeable battery and operable to acquire the power information corresponding to said rechargeable battery;a communication interface coupled to said portable electronic device;a power outputting module coupled to said rechargeable battery;a power transferring port configured for coupling to the electrical appliance;a switching unit coupled between said power outputting module and said power transferring port and operable to make or break a circuit path between said power outputting module and said power transferring port; anda control unit coupled to said information acquiring module, said communication interface, said power outputting module, and said switching unit;wherein said portable electronic device is operable to send an information request to said control unit via said communication interface,wherein said control unit is responsive to the information request from said portable electronic device to control said information acquiring module for acquiring the power information and to send the power information to said portable electronic device via said communication interface, andwherein said portable electronic device is configured to control said control unit for controlling switching operation of said switching unit.
