Limitations
This page outlines the current limitations of our OCPP implementation. Understanding these constraints is crucial for proper integration and usage of our charging system.
Disclaimer: OCPP is currently in beta release with firmware version >= 328. We strongly recommend using this beta release exclusively in test environments. Your feedback is greatly appreciated and will help us improve the final offering of OCPP. Other features of firmware version 328 can be used in production safely.
Network Connectivity
WiFi Only
- Limitation: When configured for OCPP, chargers operate exclusively on WiFi.
- Impact: No 4G connectivity available for OCPP communication.
- Note: Ensure reliable WiFi coverage in deployment areas.
Charging Management
No Smart Charging or Current Limits
- Limitation: Smart charging features and dynamic current limiting are not supported.
- Impact: Unable to adjust charging rates based on grid conditions or user preferences.
No Free Charging
- Limitation: Free charging sessions are not supported.
- Impact: All charging sessions require authorization.
Configuration and Authorization
No Persistence of Config Keys
- Limitation: Configuration keys are not persistently stored.
- Impact: Settings may revert after charger reboots or power cycles.
No Local Authorization
- Limitation: Local authorization lists cannot be sent to charge points via OCPP.
- Impact: No storing of RFID tags on the charge point, all sessions must be authorised by the central system.
Charging Behavior
No Offline Charging
- Limitation: Charging sessions cannot start without an active connection to the central system.
- Impact: Chargers become inoperable during network outages.
Authorize-then-Charge Limitation (Version 1.0.0)
- Limitation: Version 1.0.0 does not support the "authorize first, then charge" workflow.
- Impact: May affect certain authorization scenarios, e.g. tapping the RFID before plugging the car in.
Data Reporting
Limited MeterValues
- Limitation: Voltage and temperature readings are not included in MeterValues.
- Impact: Reduced granularity in charging session data.
No Offline MeterValue Queuing (Version 1.0.0)
- Limitation: Version 1.0.0 does not support queuing of MeterValues when offline.
- Impact: Potential loss of charging data during network interruptions.
Important Notes
These limitations apply to the current beta version (1.0.0) of our OCPP implementation and may be addressed in future updates.
