The function of the new energy electric vehicle charging pile is similar to the refueling machine in the gas station. It can be fixed on the ground or wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. Different voltage levels charge various models of electric vehicles. 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. New energy electric vehicle charging piles generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to perform corresponding charging methods, charging time, and cost data. Printing and other operations, the new energy electric vehicle charging pile display screen can display the charging amount, cost, charging time and other data.
