Title:
CHARGING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/204059
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a power supply system contributing to suppressing the instability of a power system by reducing cases in which an unbalance occurs among three phases and also to provide a three-phase/single-phase inverter used in the system. The present invention is a charging system that rapidly charges an electric vehicle and/or a battery system while supplying power to each customer from a commercial system and is characterized by comprising: three-phase wiring and/or single phase wiring for supplying power to the interior of each customer from a pole-mounted transformer disposed in the commercial system; the number of ACDC converters according to the number of wiring lines; and one or more DCAC inverters connected at a stage subsequent to the ACDC converters. The charging system branches the wiring connecting the ACDC converter and the DCAC converter to each other and connects the electric vehicle and/or the battery system in parallel, thereby performing rapid charging with direct current. The charging system solves the first problem described above.
