Abstract

The invention provides a power management system and a power management method. The power management system includes a power chip, which is used for storing power source information; a base block management controller (BMC), which is used for obtaining the power source information stored by the power chip through a power management bus (PMBUS), wherein the power chip is provided with a PMBUS communication interface, and the power chip is connected with the BMC through the PMBUS. The power management system and method are able to output the power source information to the BMC.

Description

technical field [0001] The invention relates to the field of digital power supply, in particular to a power supply management system and method. Background technique [0002] A power supply is a device that converts other forms of energy into electrical energy to provide electrical energy to other devices. In order to better control the power supply, it is necessary to monitor the working status of the power supply. [0003] In the traditional power management solution, the power monitoring function is generally placed separately on the DC-DC voltage regulator, which can only monitor whether the power supply is faulty, and cannot output the power supply information of the power supply. Contents of the invention [0004] The power management system and method provided by the present invention can output power information to a BMC (Baseboard management controller, baseboard management controller). [0005] In one aspect, the present invention provides a power management sy...
