Problems solved by technology

[0002] With the continuous depletion of petroleum energy, economical, efficient and renewable energy electric vehicles are constantly accepted by people. Because electric vehicles have different uses and manufacturers are not the same, so the charging types of electric vehicles are roughly divided into three types, DC charging , single-phase AC charging and three-phase AC charging, so the charging piles in the charging station are generally divided into DC charging piles, single-phase AC charging piles and three-phase AC charging piles, and even some charging stations are also divided into DC charging piles. Charging stations, single-phase AC charging stations and three-phase AC charging stations lead to the corresponding charging types of vehicles can only find the corresponding charging stations or even charging piles for charging, which results in a relatively small number of charging piles for electric vehicles. Greatly reduces the convenience of charging
