Share Charging's SECC products were the first in China to obtain TÜV Rheinland and DEKRA certification.

SECC, short for Smart Electric Vehicle 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.

SHARE Charging EVCC Compatible with All Domestic New Energy Vehicles

The EVCC (Electric Vehicle Communication Controller) is a key component in the overall charging solution, acting as the bridge between the electric vehicle and the charging station.
It supports major communication standards including ISO 15118, DIN 70121, SAE, and CHAdeMO, and provides UDS diagnostic services as well as V2G and V2V communication support.
Installed on the vehicle side, the EVCC converts GB/T CAN communication into PLC communication, enabling domestic Chinese NEVs to connect with international charging systems. With simple adaptation and installation, vehicles equipped with SHARE Charging EVCC can be quickly prepared for overseas markets such as Europe, the Americas, and Asia.
During charging, the EVCC exchanges real-time information with the BMS and OBC, confirms whether the vehicle is ready to charge, and helps ensure a stable, safe, and reliable charging process.
