20kW DC wall mounted/column type charging pile

The DC charging station mainly consists of two functional modules: human-computer interaction and internal control. The human-computer interaction part consists of a smart meter, a card reader, and a display unit, which are used to set charging and billing methods, set charging process parameters, identify charging cards, etc. The internal control module consists of a main control board, power supply, control and protection unit, and backend communication. It completes the startup, operation, real-time monitoring, and shutdown of the charging process, and can transmit data in real-time to the backend through various communication methods.
