Three major consumers, one night of cheap hours
Many modern households have several large loads waiting for the night: an EV, a home battery, and a water heater. This scenario shows how Leafy Energy orchestrates them together.
Scenario goals
- The EV must reach its target SOC before the morning commute.
- The battery should be charged for expensive daytime hours.
- The boiler must have enough hot water for the morning peak.
Input data used by Leafy
- State of charge and target SOC for the EV.
- Current state of charge and minimum targets for the home battery.
- Boiler water temperature and comfort limits.
- 24-hour price forecast.
Orchestration logic (simplified)
- Leafy reserves cheap hours and available power for the EV first (critical for mobility).
- Remaining cheap blocks and spare capacity are shared between battery and boiler.
- During ultra-cheap hours, all three may charge simultaneously within the main fuse limit.
- When price levels increase, the EV gets priority; the other two are slowed or paused.
Visualisation in the Leafy dashboard
- A timeline with three coloured bars (EV, battery, boiler).
- An overlay showing price blocks and total power per hour.
- A summary of cost savings compared to “everything on all night”.
This scenario is perfect for demos aimed at technically inclined customers who want to see how multiple devices respond collaboratively to dynamic tariffs and grid limits.
