Knowing that electricity prices change is different from knowing what to do with tonight's charge. EVCharge.mobi helps you explore lower-price periods, then use Smart charging on a connector with a dynamic tariff. Work from the energy you need and the time the car can remain connected.
Originally published in 2025. The EVCharge.mobi workflow was updated in September 2026; the historical discussion below retains its original context.
Open Cheapest EV Charging Hours, choose the bidding zone and enter an energy target, charging power and efficiency. Selected periods may be separated by gaps; inspect the plan instead of assuming one overnight block.
The tool estimates market energy cost. It does not control the charger or include every component of your tariff. In the EVCharge app, open your connector and choose Smart when it has a dynamic tariff. Review and adjust the periods before confirming.
For a repeating owner-managed workflow, Charger settings → Automation offers Smart automation with a selected vehicle and daily ready time. It requires a vehicle in your account and a dynamic tariff. Follow the scheduling guide and check the completed session in Insights.
When comparing with public charging, use the public charger's actual tariff. A wholesale price chart is not a cross-network price comparison.
Every afternoon, power exchanges post tomorrow’s 24 prices. On windy nights, some hours even drop to zero or below. For EV drivers, this isn’t an abstract market quirk — it’s a timetable for cheap charging windows you can set once and forget.
Two shifts made day‑ahead prices practical for households:
Key stat: In time‑of‑use markets, night rates can be up to ~70% cheaper than typical daytime unit rates, though your mileage varies by country and supplier.
Public DC can be cheaper temporarily when:
Rule of thumb (illustrative): detour if Public_kWh × kWh_needed + travel_cost < Home_kWh(hour) × kWh_needed + value_of_time. Your app can surface this with live prices and distance.
Do I need a smart meter? For household dynamic billing, yes. For public charging, prices are shown before start either way.
Where do I see tomorrow’s prices? Many suppliers/apps show them after the exchange publishes. Energy sites (Nord Pool, ENTSO‑E) also display curves.
Should I chase negative prices? If available under your contract, schedule them — but a simple cheap‑hours window already captures most savings.
