It can be fixed on the ground or wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and parking lots or charging stations in residential areas. It can charge various types of electric vehicles according to different voltage levels. The input end of the new energy electric vehicle charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging the electric vehicle. The charging pile of new energy electric vehicles generally provides two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the man-machine interactive operation interface provided by the charging pile to print the corresponding charging method, charging time and charge data.
