CHP control via State-of-Charge (SoC)

Controls a CHP device (Combined Heat and Power Unit, German: BHKW - Blockheizkraftwerk). The Controller is used to signal the CHP to turn 'ON' when battery SoC is low (battery empty); and signals it to turn 'OFF' when SoC is high (battery full), based on the SoC percentage. This controller needs four parameters,

  • State of Charge(Soc) of the ESS.

  • Low Threshold(LT) Soc

  • High Threshold(HT) Soc

  • Output channel to signal.

The Soc of the Ess is compared with the LT and HT, and The following operations or state change is performed.

  • If the Soc is less-than("<") LT, signal is sent to the Output channel which eventually turns the CHP device 'ON'.

  • If the Soc is greater-than(">") HT, signal is sent to the Output channel which turns the CHP device 'OFF'.

  • Any other conditions the there is no change in the State of the CHP device.

Configuration

  • Component-ID Unique ID of this Component (id), e.g. "ctrlIoAlarm0", "ctrlIoAlarm1"

  • Alias Human-readable name of this Component; defaults to Component-ID (alias)

  • Input Channels Addresses of the input State-Channels (inputChannelAddress), This is a array of input state channels.

  • Output Channel Channel address of the Digital Output that should be switched (outputChannelAddress)

  • Low Threshold Low boundary of the threshold

  • High Threshold High boundary of the threshold

Example Configuration

  • Component-ID : ctrlChpSoc0

  • Alias : myChpCtrl

  • Input Channels : _sum/EssSoc

  • Output Channel : io0/Relay1

  • Low Threshold 25

  • High Threshold 75

_sum/EssSoc - represents the Soc channel of the ESS0, io0/relay1 - represents the relay 1 of the relay board.
