Yes, a Charge Point Operator can use OCPP 2.0.1 to configure different power scaling policies for individual connectors within a single DC fast charger during peak grid demand periods. The protocol supports dynamic control of power levels per connector, enabling operators to manage load distribution and grid impact more effectively.
How OCPP 2.0.1 Enables Granular Power Control
OCPP 2.0.1 introduces enhanced capabilities for managing power allocation across multiple connectors on a single charging station. Through the use of SetChargingProfile and GetChargingProfiles messages, operators can define distinct charging profiles for each connector. This allows for fine-grained control over power limits, which can be adjusted in real time based on grid conditions or operational needs.
For example, during high-demand periods, one connector might be limited to 50 kW while another remains at full capacity. These policies are enforced by the charging station’s backend system, ensuring compliance with local grid constraints or operator-defined rules.
This granular control is particularly useful in commercial or fleet environments where different vehicles may have varying power requirements and charging schedules. It also supports smart charging strategies that align with renewable energy availability or time-of-use tariffs.
Practical Application for Charge Point Operators
In practice, this feature allows operators to maintain service levels while reducing strain on the electrical grid. For instance, if a site experiences a sudden spike in demand, an operator can reduce power to certain connectors without completely halting charging for others.
Operators can also use this capability to comply with local utility regulations or participate in demand response programs. By adjusting power scaling policies dynamically, they can avoid overloading local transformers or meeting specific grid management objectives.
For example, a fleet operator might configure their charging station so that electric buses use higher power during off-peak hours, but switch to lower power during peak hours to support grid stability. This flexibility is essential for scalable and sustainable EV infrastructure deployment.
