When is charging cheapest?
On a dynamic tariff you pay the wholesale price for every hour, plus the fixed components. Electricity is usually cheapest at night and around midday on sunny days, and dearest in the early evening, when demand peaks and solar output fades. A car plugged in overnight often needs only three or four hours – the planner puts them in the cheapest part of the night.
Smart charging means the wallbox or the car only charges in the cheapest hours, with pauses in between if needed. Many wallboxes and car apps do this automatically with dynamic tariffs. If you only have a start timer, choose “Timer”: the planner then finds the cheapest continuous block.
How much electricity does my car need?
Consumption figures come from the official data on every electric car newly registered in Europe (WLTP, measured at the socket, so charging losses are included). Small cars need about 14–15 kWh per 100 km, large SUVs more than 20 kWh. In winter, on motorways and on short trips with the heating on, consumption is higher – just enter your own figure.
Economy 7 and EV tariffs
Many British homes on Economy 7 pay a lower rate for seven hours at night, and several suppliers offer EV tariffs with a cheap overnight window. On those tariffs the cheap hours are set by the tariff, not by the wholesale price. The planner shows when wholesale electricity is cheapest, which matters on smart tariffs that follow the market.
