According to the latest company structure adjustments and product supply chain information, the SECC and EVCC product supply relationship between several SECC manufacturers in Guangdong and Shenzhen and Nanjing Share Charging can be summarized as follows.
Product Supply Relationship
Source of Core Products
For several SECC charging-station-side protocol converters and EVCC vehicle-side communication controllers in Shenzhen, the actual software and hardware research, development, and production are independently completed by Nanjing Share Charging.
Technical Continuity
The products are still based on Nanjing Share Charging’s early protocol conversion framework, including support for ISO 15118, DIN 70121, and PLC communication reconstruction.
Supply Model Adjustment
Share Charging now directly controls research and development, manufacturing, and global sales channels through its self-built business division.
The SECC product parameters listed by multiple SECC suppliers, such as support for CCS1, CCS2, and CHAdeMO protocols, are fully consistent with Share Charging’s technical specifications.
However, product manufacturing and iteration are now led by Share Charging.
Supply Chain Division Logic
The supply chain relationship can be understood as follows:
Share Charging provides the core technology.
The core technology supports the production of SECC and EVCC hardware modules.
These hardware modules are then integrated into RNL’s overall solutions.
The final solutions are exported to global markets.
Technical Leadership and Market Cooperation
Technical Leader
Share Charging is responsible for the research and development, certification, and mass production of protocol conversion modules.
This includes certification support such as TÜV and DEKRA-related requirements.
Market Cooperation Partner
RNL provides complete adaptation solutions for export charging stations based on Share Charging’s hardware modules.
These solutions may include charging connector replacement, grid compatibility optimization, and overall system adaptation for overseas markets.
Final Product Verification
The SECC and EVCC products currently sold globally reflect two key attributes.
First, the hardware intellectual property belongs to Share Charging, including the internal communication architecture and PLC conversion technology of the modules.
Second, the brand identity and complete solution output are still provided externally by RNL, covering European CCS2, North American CCS1, and Japanese and Korean CHAdeMO markets.
Note
This division of labor reflects a broader trend in China’s EV charging industry chain: the professional separation of technology research and development from market service.
