[0002] A charging pile is a device that replenishes electricity for electric vehicles. Its function is similar to that of a gas pump in a gas station. It can be fixed on the ground or on a wall and installed in public buildings (charging stations, shopping malls, public parking lots, etc.) and parking lots in residential areas. It can charge various types of electric vehicles according to the adjusted voltage and current. 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 corresponding charging operations and print cost data. The charging pile display can display data such as charging capacity, cost, and charging time.
