Power supply management device and method

Abstract

The invention provides a power supply management device for managing a power supply of electronic equipment. The power supply management device comprises a plurality of digital power supplies and an embedded controller, wherein the plurality of digital power supplies are used for supplying power to a plurality of power utilization units of the electronic equipment separately; and the embedded controller is in communication connection with the plurality of digital power supplies through a system management bus, and can acquire power supply state information of each digital power supply; and the embedded controller is further connected to a basic input / output system of the electronic equipment, so that a driving program of an operation system of the electronic equipment can access the embedded controller through the basic input / output system. The invention further provides a power supply management method. The device and method sufficiently utilize the advantages of the digital power supplies and utilize the communication function among the embedded controller, each digital power supply and the driving program, so that a user can detect power consumption conditions of each power utilization unit and each power supply in real time, and can properly control the performance of the system.

Description

Technical field [0001] The present invention relates to a power management device and method, in particular to a power management device and method applied to electronic equipment. Background technique [0002] Traditional power applications can only complete basic power supply functions, and cannot realize intelligent monitoring and reporting on the power consumption and power status of each power consumption unit. [0003] There are two solutions in the prior art as follows: [0004] 1) Use a current detection resistor at the back end of each battery to detect the current of each power supply. The disadvantage of this scheme is that it can only measure the voltage of each power-consuming unit and the current flowing through the detection resistor through pure hardware, so as to calculate the power consumption of the power-consuming unit; [0005] 2) Using digital power instead of traditional power, digital power can detect the voltage, current, efficiency of the power supply, and w...
