Abstract

The present invention discloses an electronic system and a method for executing power source management to the electronic system. The electronic system comprises a plurality of main power sources, a secondary power source, and a power source management unit which is coupled with the plurality of power sources and the secondary power source. The plurality of main power sources can charge the secondary power source. The power source management unit selectively transmits the electrical energy of each main power source to the system load according to the electrical energy requirement of system load. The power source management unit outputs the electrical energy of second power source to the system load when the electrical energy requirement of system load exceeds the total electrical energy of main power sources thereby preventing electrical energy halt of system load. Furthermore the charging requirement of secondary power source under different charging period or charging mode can be satisfied.

Description

technical field [0001] The invention relates to a power management system. Background technique [0002] An electronic system can be powered by multiple power sources, such as a primary power source and a secondary power source. Typically, these power supplies are managed by a power management device. The main power source may be a power source with limited power such as a fuel cell (or an AC / DC converter). The secondary power source may be a rechargeable battery pack, such as a lithium-ion battery pack. Typically, a fuel cell powers the system, and a lithium-ion battery pack provides backup power for the system. If the load on the system is high, the system's demand for electrical energy may exceed the electrical energy of the fuel cell. In order to provide enough power for a system with a high load, the power management device can control the discharge of the fuel cell and the lithium-ion battery pack at the same time. [0003] The power management devices mentioned a...
