Abstract: A battery charge/discharge management system and method charge a battery according to an operation state of the battery. The system includes a reading module that reads a parameter of the battery; an analysis module that analyzes the parameter of the battery and determines the operation state of the battery according to the parameter of the battery so as to obtain a discharge parameter and record a discharge curve at that time; and a charging module having a mapping table that maps a plurality of discharge curve models and a plurality of charge modes, the charging module obtaining a discharge curve model according to the discharge curve and charging the battery based on a charge mode to which the mapping table maps the discharge curve model. As such, the battery is prevented from staying under high temperature and protected from being damaged by over charging/discharging.

Abstract: A power management system applicable to regulating a power supplied to an electronic device having a plurality of electronic elements includes a detection module that detects execution modes of the electronic elements and generate detection data, an analysis module that analyzes the detection data to generate process commands corresponding to the execution modes of the electronic elements, and a process module that gradually regulates the power via a power control mode of the electronic device according to the process commands, the power control mode including a light power supply, a sleep power supply and a turn-off power supply A power management method is also provided for regulating a power supplied to an electronic device having a plurality of electronic elements gradually.
