There are charging piles in the Beiliu service area. The function of the charging pile is similar to that of a gas dispenser in a 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 residential areas. In the charging station, various types of electric vehicles can be charged according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. 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 operations such as corresponding charging methods, charging time, and cost data printing. The charging pile display screen can display data such as charging capacity, cost, charging time, etc.
