Is the Highway Charging Pile Crowded During National Day?

[McSimon]

National Day highway charging piles are crowded. Classification of car charging piles: The input power of car charging piles is divided into two types: 220V single-phase electricity and 380V three-phase electricity. Charging piles are divided into AC charging piles and DC charging piles: AC charging piles provide power input for electric vehicle chargers. Since the power of the onboard charger can achieve fast charging, DC charging piles are used to achieve fast charging. DC charging piles are fixedly installed outside the electric vehicle and connected to the AC grid to provide DC power to non-vehicle electric vehicle batteries. Introduction to AC and DC charging piles: The power supply device of the DC charging pile inputs three-phase four-wire AC380V±15%, frequency 50Hz, and outputs adjusted DC power directly to charge the electric vehicle battery. Since the DC charging pile adopts a three-phase four-wire system, the power supply provides sufficient power, and the voltage and current adjustment range meets the fast charging requirements. The metering, communication, and extended billing functions of DC charging piles are similar to those of AC charging piles, such as the Shouyuan electric vehicle charging pile.
