Physical cable swapping between CCS and CHAdeMO charging stations is not possible due to different connector designs and safety mechanisms. OCPP 2.0.1 handles connector type validation through local device logic and pre-configured station settings, ensuring compatibility without requiring cloud connectivity.
Why connector types cannot be interchanged
CCS (Combined Charging System) and CHAdeMO use entirely different physical plug designs. CCS connectors have a specific pin configuration for DC charging, while CHAdeMO uses a distinct layout with its own set of contacts. These differences make mechanical interchange impossible, as the physical fit and electrical interface are incompatible.
Additionally, each connector type has unique safety protocols embedded in the charging station’s firmware. Attempting to use a cable from one standard on a station designed for another would bypass these safety checks, potentially leading to damage or hazardous conditions.
Charging stations are engineered to recognize and validate connector types at the hardware level. This prevents incorrect connections and ensures that only compatible cables are used for each charging protocol.
How OCPP 2.0.1 validates connector types offline
OCPP 2.0.1 enables offline validation by pre-configuring supported connector types within the charging station’s local memory. When a cable is inserted, the station checks against this predefined list before initiating communication with the central system.
This approach allows charging operations to proceed even without an active internet connection. The validation process occurs at the edge, using local logic rather than relying on cloud-based verification.
For fleet operators or enterprise deployments, this offline capability ensures consistent operation across networks where connectivity may be intermittent. It also reduces latency in connection initiation and improves overall system reliability.
