Design

To create a schedule optimised by energy cost:

Once customer completes the Connect flow, or if you created their tariff via the API:

• Create a default schedule that provides a fixed number of daily “on” hours when the tariff is low (i.e. 5 hours between 8pm and 6am on the following day).
• Allow the customer to change that schedule by setting a choice of:
  • Number of daily “on” hours (add weekday/weekend and so on), or/and
  • When the “on” period must end (i.e. complete charging by 6 am) or
  • Absolute tariff threshold (i.e. “on” when the tariff is below $0.15/kWh), or
  • Relative tariff threshold (i.e. “on” when the tariff is below 40% daily average).

To keep the schedule aligned with tariff changes:

• When an energy user (i.e. an EV) connects to your device or scheduled daily:
  • Pass schedule settings to the API,
  • Receive actualised schedule (slots),
  • Apply this actualised schedule to your device.

To log the amount of transferred energy:

• During or after the energy transfer, log it to meter records API under IMPORT tariff.
• Log any energy from local generation (i.e., solar) under the LOCAL tariff.

To display the cost of transferred energy:

• When you want to display the energy cost, call the API to get it in real-time, aggregated by (charging) session or day/month/year.
