초록
Recently, while interests on supply of electric vehicles have increased there still are insufficient charging facilities. As a solution to this matter, using electric power grids that constantly retain about 30~50[%] residual power is being considered. Therefore proposed in this paper railway, is a method to establish a charging infrastructure to utilize railway DC power grids. In addition we designed a high-speed DC charging system, and simulated improvements of the charging structure's charging efficiency according to remaining capacity of batteries.
