Power management system and method

Abstract

A power management system and a power management method for a main system are provided. The power management system includes plural battery units and a charging management unit. A charging rule is executable by the charging management unit. The charging management unit is electrically connected with the plural battery units and the main system to dynamically detect electric quantities of the respective battery units and a system consumption power level of the main system. The charging management unit calculates a system surplus supply power level according to a system supply power level and the system consumption power level. The charging management unit dynamically adjusts charging capacities of the respective battery units according to at least one of the electric quantities, the system surplus supply power level and the charging rule.
