Share Charging's SECC products were the first in China to obtain TÜV Rheinland and DEKRA certification.
SECC, short for Supply Equipment Communication Controller, is a key core component in the complete charging solution. It serves as the communication bridge between European-standard charging stations and the vehicle-side EVCC, helping the charging station convert GB/T communication protocols into European and American standard communication protocols.
Installed on the charging station side, the SECC can convert GB/T CAN communication into PLC communication. When the charging station charges an electric vehicle, the SECC communicates with the EVSE to send and receive information, confirming whether the charger is ready to provide charging service and whether the electric vehicle is also in a charge-ready state. During the charging process, both sides continuously exchange the required information to ensure safe and reliable charging.

CCS1/CCS2 EVCC Controller for Electric Vehicles and EV Test Systems
The Electric Vehicle Communication Controller (EVCC) is a key component of the overall EV charging solution, serving as the communication bridge between the electric vehicle and the charging station.
It supports mainstream communication standards, including ISO 15118, DIN 70121, SAE, and CHAdeMO, and provides UDS diagnostic services, as well as V2G (Vehicle-to-Grid) and V2V (Vehicle-to-Vehicle) communication support.
Installed on the vehicle side, the EVCC converts GB/T CAN communication into PLC (Power Line Communication), enabling Chinese new energy vehicles to connect to international charging systems. With straightforward integration and installation, vehicles equipped with the SHARE Charging EVCC can be efficiently adapted for overseas markets, including Europe, the Americas, and Asia.
During the charging process, the EVCC exchanges information in real time with the Battery Management System (BMS) and the On-Board Charger (OBC) to confirm whether the vehicle is ready for charging, thereby ensuring a stable, safe, and reliable charging process.
