In response to the demand for domestic electric vehicles and charging piles to enter the overseas market, this paper focuses on the dynamic output characteristics of CCS charging piles. Using Keysight's SL1040A test equipment, data are collected from 9 models of CCS2 DC charging piles in different phases—voltage ramp-up, current ramp-up, stable output, and discharge phases. Then it analyzes the rate characteristics, deviation values, and accuracy performance of each phase, providing data support for the protocol adaptation of domestic electric vehicle charging systems and the design of domestic charging piles for overseas markets. Meanwhile, combined with the latest AFIR Regulation (Alternative Fuels Infrastructure Regulation) issued by the European Union, this paper conducts research and analysis on the export policies of the new energy charging pile industry.
