POWER SUPPLY CONTROL SYSTEM AND CONTROL METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/187998
Kind Code:
A1
Abstract:
Provided are a power supply control system (100) and a control method thereof, which belong to the field of charging station control. The power supply control system (100) is used in an electric vehicle charging station having an energy storage system (30). The power supply control system (100) comprises: a transformer (10) connected to a power grid; an output socket (20), which is connected to the transformer (10) by means of an alternating-current bus and is used for connecting to an electric device in the electric vehicle charging station; and an energy storage system (30), which comprises an AC/DC bidirectional converter (31), and an energy storage battery (32) connected to the alternating-current bus by means of the AC/DC bidirectional converter (31), wherein the energy storage system (30) is configured in such a manner that same is controlled to switch the AC/DC bidirectional converter (31) to be in an inversion state when the power supply control system (100) is in an uninterruptible power supply mode, the energy storage system (30) does not output electric energy when the voltage of the power grid is normal, and the electric energy is provided only by the energy storage system (30) when the voltage of the power grid is abnormal. By means of the power supply control system (100) and the power supply control method, the cost of achieving the uninterruptible power supply function can be reduced.
