pole-installed electric vehicle charging apparatus system and method based on load of transformer connected to distribution line

摘要

The present invention relates to an electric vehicle charging apparatus installed in an electric pole, which provides an environment in which power converted by a transformer connected to a power distribution line is safely used in charging an electric vehicle. The electric vehicle charging apparatus according to an embodiment of the present invention comprises: a first port configured to supply power to an electric vehicle; a second port configured to receive power converted by a transformer connected to a power distribution line; a blocking part switching an open/close state between the first port and the second port; and a control part that receives load information of a transformer and controls the blocking part to electrically open between the first port and the second port when a load amount corresponding to the load information is larger than a reference load amount.
