PROBLEM TO BE SOLVED: To provide simple structured and flexibly operable charging equipment while combining a plurality of power converters with a system power source, and an energy management method for the charging equipment.SOLUTION: The charging equipment collects to a DC bus DC power supplied from a plurality of power supply devices, to be used to charge a storage battery mounted on an electric automobile. In the energy management method for the charging equipment, each power supply device is operated by mutually independent automatic control according to the voltage variation of the DC bus. This makes no need of an upper-level control unit for collectively controlling a plurality of power supply sources, and enables combining the plurality of power supply devices with a simple structure of connecting each output terminal to the DC bus, as well as flexible operation of the overall charging equipment. |
