    • applyDisplayText

      public boolean applyDisplayText(String text) throws OpenemsException
      Description copied from interface: ManagedEvcs
      Command to send the specified text to the EVCS display, if supported

    • pauseChargeProcess

      public boolean pauseChargeProcess() throws OpenemsException
      Description copied from interface: ManagedEvcs
      Command to pause a charge process of the EVCS.

      In most of the cases, it is sufficient to call the method #applyChargePowerLimit(Integer) with 0 as power but sometimes it needs extra commands to initiate a pause of charging.

      Specified by:
      pauseChargeProcess in interface ManagedEvcs
      Returns:
      boolean if the command was applied to the EVCS
      Throws:

    • getConfiguredMinimumHardwarePower

      public int getConfiguredMinimumHardwarePower()
      Description copied from interface: ManagedEvcs
      Minimum hardware limit in W given by the configuration.

      This value is taken as a fallback for the ChannelId#FIXED_MINIMUM_HARDWARE_POWER channel. As the configuration property should be in mA for AC chargers, make sure that the value is converted to W. Example: Math.round(current / 1000f) * DEFAULT_VOLTAGE * Phases.THREE_PHASE.getValue();

      Specified by:
      getConfiguredMinimumHardwarePower in interface ManagedEvcs
      Returns:
      minimum hardware limit in W

    • getConfiguredMaximumHardwarePower

      public int getConfiguredMaximumHardwarePower()
      Description copied from interface: ManagedEvcs
      Maximum hardware limit in W given by the configuration.

      This value is taken as a fallback for the ChannelId#FIXED_MAXIMUM_HARDWARE_POWER channel. As the configuration property should be in mA for AC chargers, make sure that the value is converted to W. Example: Math.round(current / 1000f) * DEFAULT_VOLTAGE * Phases.THREE_PHASE.getValue();

      Specified by:
      getConfiguredMaximumHardwarePower in interface ManagedEvcs
      Returns:
      maximum hardware limit in W
