Yes, a Charge Point Operator can configure different charging tariffs for workplace and visitor sessions within the same location using OCPP 2.0.1. The protocol supports session-based tariff rules that allow operators to define distinct pricing structures based on user type, time of day, or other criteria directly at the charging station or through the Charging Management System (CMS).
How OCPP 2.0.1 Enables Flexible Tariff Rules
OCPP 2.0.1 introduces enhanced tariff management capabilities that let operators assign specific pricing policies to different user groups or session types. For example, a workplace charging station can be configured so that employee sessions are billed at a flat rate or included in a monthly subscription, while visitor sessions are charged per kWh or based on time spent.
This functionality is implemented through the TariffData and TransactionData elements in OCPP 2.0.1, which allow operators to define tariffs that are applied dynamically during a charging session. These tariffs can be set up in the CMS and pushed to the charging point, ensuring that the correct pricing is applied without requiring manual intervention.
Operators can also use these tariff rules to support dynamic pricing models, such as time-of-use rates or demand-based pricing, which are increasingly important for grid stability and cost optimization.
Practical Implementation for CPOs
In practice, configuring different tariffs requires setting up user roles or tags within the CMS to distinguish between employee and visitor accounts. The system then applies the appropriate tariff based on the session’s identity, ensuring that billing aligns with the intended usage model.
For instance, a commercial building might use a single charging station for both employees and guests. The CPO can define that employee sessions are free or discounted, while guest sessions are charged at a standard rate. This setup supports both operational efficiency and user satisfaction.
These tariff configurations are especially useful for fleet operators or enterprises that want to incentivize off-peak charging or manage access to charging infrastructure based on user categories.
