Smart tariff EV charging without home energy conflicts
When EV charging is cheap, it can still be operationally expensive if it competes with battery reserve, heating demand or export value elsewhere in the property.
Private beta rollout
This use case already exists in real homes, even if rollout is still selective.
The product foundation is built around conflicts like this one. Public onboarding is being paced carefully, so the next step is to review your exact device and tariff mix.
Best-fit homes are invited first
Homes where multiple devices already interact are reviewed first — rollout is selective and supported.
Combination creates the value
Whole-home value comes from how devices work together, not from any single device in isolation.

Best fit
For households using off-peak or intelligent EV tariffs who need the charger to work with the rest of the home, not against it.
Friction today
- The charger can consume the same overnight window the battery wanted.
- The car can look cheap to charge while forcing expensive daytime import later.
- Most apps optimise the charger but do not explain the whole-home result.
What improves
- Separate EV load from the rest of the house so its cost and timing are visible.
- Understand overnight charging in the context of battery reserve and next-day solar.
- Reduce hidden charger-versus-battery conflicts in smart tariff homes.
Typical workflow
- 1
Connect the tariff and charger context alongside any battery or solar devices.
- 2
Use daily reporting to compare charger behaviour against total import and net cost.
- 3
Tune the setup around real whole-home outcomes rather than individual device wins.

Solis
Connect Solis hybrid inverters to 1app.energy to see live solar, battery, grid and home demand in one place, then automate battery charge decisions around tariff windows.
myenergi Zappi
Connect your myenergi Zappi charger to see EV charging in context with solar, battery and tariff data instead of guessing whether the car is stealing the cheap window.
Octopus Energy
Connect Octopus tariffs to turn raw device telemetry into cost-aware actions, daily savings reporting and smarter battery decisions.
Related tariff guides
These tariff pages explain the pricing context that usually drives this use case.
Octopus Agile automation
Octopus Agile changes import price every half hour. The real question for battery, EV and heat-pump homes is whether the house can respond to those price signals without creating new conflicts.
Octopus Go battery and EV optimisation
Octopus Go is simpler than Agile on paper, but homes still need to know whether the fixed off-peak window is serving the car, the battery and the house in the right order.
Octopus Intelligent Go coordination
Octopus Intelligent Go creates EV-led charging windows, but battery logic, charger behaviour and whole-home demand still need to be interpreted together.
Smart controls that usually fit this problem
These mode pages explain what battery strategy tends to work best once this use case shows up in a real home.
Autopilot
The best starting mode for most homes. Autopilot decides when to charge, hold, or export by balancing tariff value, home coverage, refill confidence, and your protected minimum battery SoC. Choose Balanced for a calmer default or Aggressive for stronger value seeking.
Home First
A simpler home-first mode. It prioritises running the home from your own solar and battery first, minimises grid dependence, and avoids optimiser-led battery export.
Manual Control
A support-style page for advanced users. Manual Control keeps the automation framework in place but follows your fixed current choices more directly, with safety caps and backend guardrails still applied.
