ELECTRICAL VEHICLE CHARGING AUTOMATION SYSTEM AND CONTROLLING METHOD THEREOF

摘要

An electrical vehicle charging automation system and a controlling method thereof are provided. The system comprises at least one charger (61) and a controller (41, 51). The controller (41, 51) which is a central controller or a distributed controller comprises: a charging and discharging management module (414, 514) for managing the charging and discharging of the charger (61); a data module (415, 515) for storing and sharing information; an interface (416, 516) connected to a converter of the charger (61); a management module (411, 511) and a human machine interface (410, 510) for supervisory and management; a protection and control module (413, 513) for protecting and controlling electrical vehicle charging stations; and a coordination module (412, 512) for coordinating the controller (41, 51) with a distribution management system (31) connected to the electrical vehicle charging automation system. The method comprises the step: controlling the active power output of the charger (61) according to the real-time information collected from the charger (61) and/or the frequency or active power requirement from the distribution management system.
