Multi-function charger for electric vehicle for DC distribution network using large capacity DC-DC converter

摘要

The present invention relates to a multi-function charging device for an electric vehicle for a DC power distribution network using a large-capacity DC-DC converter, and a large-capacity DC-DC converter is supplied with electric power transmitted from a DC power supply bus. In order to stably charge the electric vehicle, a number of charging connectors are pulled out. Conversely, when the electric power required for the operation of the railway vehicle is insufficient, the electric vehicle's electric power is converted into railway electric power through the control of the central remote management system. The present invention relates to a multi-function charging device for an electric vehicle for a large-capacity DC power distribution network that can be used and can display a charging-related information by attaching a small panel to each charging connector connected to the electric vehicle.
