The 60kw/90kw integrated DC charging pile integrates the charging pile, charging interface, human-computer interaction interface, communication, billing, and other parts into a whole. It is suitable for outdoor DC fast charging of electric vehicles, and has the ability to safely and automatically charge the power battery of electric vehicles. The charging pile dynamically adjusts the charging current or voltage parameters based on the data provided by the battery management system (BMS), executes corresponding actions, and completes the intelligent charging process. At the same time, the standby screen displayed on the screen and the display before and after charging can both support the setting and configuration of customized advertising screens. Electric vehicles such as electric cars, electric taxis, and electric buses that meet the DC interface standards provide DC charging services.
