Title:
ELECTRIC VEHICLE CHARGING SYSTEM, POWER MANAGEMENT DEVICE, AND ELECTRIC VEHICLE CHARGING METHOD
Document Type and Number:
WIPO Patent Application WO/2024/111117
Kind Code:
A1
Abstract:
An electric vehicle charging system (300) comprises: a charging station (6) equipped with chargers (601) that can charge electric vehicles by using power supplied from a private line (9); electric power substation equipment that supplies power to the private line (9) and a feeder (5); a power converter (8) that is installed between the feeder (5) and the private line (9) and steps down the power supplied from the feeder (5) to the private line (9); and a power management device (50) that manages the power supplied to the charging station (6) by controlling the electric power substation equipment and the power converter (8). The power management device (50) estimates, on a per-time-band basis, the power that a train (4) connected to the feeder (5) uses during powering, the regenerative power generated during braking of the train (4), and the available capacity of the electric power substation equipment, and controls, on the basis of the estimations, the electric power substation equipment and the power converter (8) so that the power supplied to the electric power substation equipment does not exceed a preset rated capacity.
