Yes, a Charge Point Operator (CPO) can use OCPP 2.0.1 to enforce real-time power throttling for individual EVs during peak grid demand periods in a multi-tenant network. The protocol supports dynamic control of charging power through RemoteStartTransaction and ChangeAvailability messages, enabling operators to reduce or halt charging based on grid conditions.
How OCPP 2.0.1 Enables Real-Time Throttling
OCPP 2.0.1 introduces enhanced messaging capabilities that allow CPOs to send commands directly to charging stations. When grid demand spikes, the system can automatically reduce the power output for specific EVs without interrupting the charging session. This is achieved through the use of PowerLimit profiles and dynamic control commands.
Operators can configure thresholds based on real-time grid data, such as load forecasts or price signals. These settings are transmitted via the Central System to individual chargers, which then adjust their output accordingly. The process is seamless for users, as the throttling occurs within the charging session rather than stopping it entirely.
This functionality is especially useful in shared or multi-tenant environments where multiple users rely on the same infrastructure. It allows the CPO to balance load distribution and maintain grid stability while still meeting user needs.
Practical Implications for Multi-Tenant Networks
In a multi-tenant network, real-time throttling helps prevent overloading the local electrical grid. For example, if a building’s transformer is nearing capacity, the CPO can reduce power to certain EVs to avoid tripping circuit breakers or causing voltage drops.
This approach also supports demand response programs, where utilities incentivize operators to reduce consumption during high-demand periods. By leveraging OCPP 2.0.1, CPOs can participate in these programs without requiring additional hardware or complex integrations.
From a user perspective, the experience remains largely unchanged. The vehicle continues charging, but at a reduced rate. This ensures that all users get access to charging, even during peak times, while supporting broader energy management goals.
