Yes, OCPP 1.6 and OCPP 2.0.1 can be used together in the same charging network, allowing legacy and modern chargers to coexist without requiring a cloud dependency. This is made possible through protocol version negotiation and support for multiple OCPP versions in a single Charging Management System (CMS).
How it works in practice
When a CMS supports both OCPP 1.6 and 2.0.1, it can communicate with chargers running either version. The system negotiates the appropriate protocol version during connection, ensuring compatibility. This allows operators to manage a mixed fleet of chargers without needing to upgrade all devices at once.
For example, a network might include older chargers that only support OCPP 1.6 alongside newer ones that support 2.0.1. The CMS handles communication with both types seamlessly, enabling centralized control and monitoring.
This capability is especially useful for Charge Point Operators (CPOs) who are transitioning to newer standards while still relying on existing infrastructure. It avoids the need for costly full replacements and supports a gradual migration path.
What this means for Charge Point Operators
For CPOs managing diverse charging fleets, supporting both OCPP versions means greater flexibility and reduced operational complexity. It allows them to maintain older chargers while integrating new ones without disrupting service or requiring additional cloud-based infrastructure.
This approach also supports compliance with evolving regulatory requirements that may mandate newer communication protocols. Operators can meet these standards incrementally, rather than all at once.
By enabling interoperability between legacy and modern chargers, OCPP 1.6 and 2.0.1 coexistence helps CPOs optimize their charging networks for performance, scalability, and cost-efficiency.
