Share Charging’s EV charger solutions are built around its independently developed SECC, or Supply Equipment Communication Controller, protocol conversion technology. This technology serves as a key bridge for enabling GB/T-standard EV chargers to adapt to global markets. The relationship can be summarized as the following technical collaboration architecture:
🔌 Technical Dependency
SECC Protocol as the Core Underlying Technology
Share Charging embeds SECC hardware modules into GB/T-standard EV chargers to convert GB/T 27930 protocol signals from the charger side into target-market standards such as CCS and CHAdeMO in real time, enabling two-way translation of charging communication protocols.
Physical Layer Reconstruction:
It converts GB/T CAN bus communication into PLC, or power line communication, to meet the physical interaction requirements of European and American CCS charging systems.
Protocol Layer Mapping:
It is compatible with international standards such as ISO 15118 and DIN 70121, and supports Plug & Charge functionality.
Modular Integration for System Transformation
Share Charging’s EV chargers can be adapted for global markets through a three-step upgrade process:

This process enables GB/T-standard chargers to output CCS protocol signals without a full hardware redesign, significantly reducing the cost of overseas market entry.
🌍 Global Adaptation Logic
Conversion Hub from Chinese Chargers to Global Chargers
The SECC module acts as a “protocol translator.” It receives GB/T commands from Chinese-standard chargers and outputs target protocols such as CCS1 for North America and CCS2 for Europe, allowing Chinese-brand EV chargers from companies such as BYD and CATL to connect directly to overseas CCS charging networks.
Closed-Loop Vehicle-Charger Communication
When used together with the vehicle-side EVCC controller, it forms a two-way communication link:
SECC, charger-side protocol conversion → EVCC, vehicle-side protocol interpretation
This ensures compatibility between GB/T-standard vehicles and overseas CCS chargers.
🛠️ Commercial Application Verification
European Market Deployment:
The solution can be adapted to 20–40kW low-power DC chargers, meeting EU CCS2 standards as well as German and Dutch grid policy requirements. It has passed TÜV and DEKRA certification.
Multi-Protocol Coverage:
It also supports North American CCS1 and Japanese CHAdeMO standards, serving charging networks in more than 70 countries and over 500 cities.
Summary
Through SECC protocol conversion technology, Share Charging transforms its EV charger products into global protocol-adaptive charging platforms.
The core technical logic is:
GB/T hardware + SECC module → real-time protocol conversion → seamless access to CCS / CHAdeMO charging networks.
