3.25 Set Charging Profile

The SetChargingProfile message in OCPP 1.6J is sent by the central system to configure a charging profile on the charge point. The profile defines charging parameters, such as power limits, start and end times, and energy consumption. It includes a charging profile ID and specifies the connector ID to which the profile applies. The charge point responds to confirm if the profile was successfully set. This helps manage charging sessions based on time, power or energy constraints.

API Syntax	Description	Input Params	Return Value
SetSetChargingProfileStatus	Sets the status of the SetChargingProfile response.	SET_CHARGING_PROFILE_STATUS_T status	void

Example:


      if((params.connectorId == GetChargePointConnectorId()))

    }


API Syntax	Description	Input Params	Return Value
GetSetChargingProfileParams	Copies parameters from the global RX_SetChargingProfile structure to the provided cur_charging_profile structure.	RX_SETCHARGINGPROFILE_T *currentChargingProfile	void

Example:

  case SET_CHARGING_PROFILE:
  {
    bool isCompositeSchedule = false;
    RX_SETCHARGINGPROFILE_T inputProfile;
    GetSetChargingProfileParams(&inputProfile);

    if (AddUpdateProfile(&inputProfile) == RETURN_SUCCESS)
    {
      LogDebug("APP_LOG", " Profile Updated successfully\n");
    }
    else
    {
      LogDebug("APP_LOG", " Failed to update Profile\n");
    }

    PrintChargingProfiles();
    ProcessSmartCharging(responsecode, isCompositeSchedule, inputProfile);
  }
  break;
