1. EVCC Core Function
As national standard electric vehicles often utilize different protocols, they must be equipped with an EVCC to establish communication with overseas charging stations. The EVCC acts as the critical communication bridge, converting the vehicle's internal protocols into a format understood by international charging infrastructure.
It manages power transmission control, data exchange, monitors battery capacity, and regulates charging power and time while recording data for management.
2. Global Standards Compatibility
Our EVCC is a comprehensive solution supporting CCS1 and CCS2 inlets. The global market is divided by various standards: China's GB/T 27930, Europe's DIN 70121 and ISO 15118, the US SAE J1772, and Japan's CHAdeMO. The EVCC overcomes these differences in communication protocols and voltage levels, allowing vehicles to be exported and charged globally.
3. Hardware & Software Conversion
Hardware Requirements:
- Replacing the charging inlet with European or American standard hardware.
- Integration of the EVCC charging communication controller.
Software Requirements:
- The EVCC facilitates communication with the BMS, converting local CAN communication to international PLC communication standards.
4. EVCC Hardware Components
The system is built upon five essential modules: Microprocessor, Power Module, Communication Module, Sensors, and Safety Protection Circuit.
