Yes, OCPP 2.0.1 supports dynamic power adjustment during an active charging session. This capability allows charge points to modify the power output in real time, based on grid conditions, load balancing requirements, or operator commands, without interrupting the charging process.
How Dynamic Power Adjustment Works in OCPP 2.0.1
The feature is enabled through the SetChargingProfile and ChangeAvailability messages, which can be sent from the Central System to the Charge Point. These messages allow for fine-grained control over power levels, including the ability to reduce or increase power while a session is ongoing.
For example, if a utility company needs to reduce demand during peak hours, the Central System can send a new charging profile that lowers the maximum power allowed. The Charge Point then adjusts accordingly, ensuring compliance without stopping the session.
This functionality is especially useful in fleet and commercial deployments where energy management is critical. It enables operators to respond quickly to changing conditions, such as grid constraints or dynamic pricing signals.
Practical Impact for Charge Point Operators
For Charge Point Operators (CPOs), dynamic power adjustment means greater flexibility in managing charging infrastructure. It allows them to balance load across multiple chargers, respond to real-time energy pricing, or comply with grid operator directives.
Consider a scenario where a large commercial facility uses OCPP 2.0.1-compliant chargers. If the building’s power capacity is nearing its limit, the CPO can reduce the power output of certain chargers without affecting the charging experience for users. This helps avoid overloading the electrical system and ensures continuous operation.
This capability also supports integration with smart grid technologies and energy management systems, making it easier to align charging behavior with broader sustainability goals.
