Your vehicle
A name to help you recognise the saved vehicle, such as “Kia EV3 Long Range”. It does not affect calculations.
The battery capacity the car actually makes available, in kWh. Search the vehicle specification for “usable capacity”, which may be lower than the advertised gross capacity.
Your usual miles per kWh. The long-term average shown by the car is best; use 3.5 if you need a starting estimate.
The fastest AC rate the car accepts for home and destination charging—commonly 7.4 or 11 kW. This is not the charger’s own rating.
The car’s maximum DC rapid-charging rate from its specification, such as 50, 150 or 250 kW.
Your tariff
Your usual home electricity price in pence per kWh, excluding the standing charge.
A typical public charger price in pence per kWh. Use the network you are most likely to use.
Your off-peak electricity price in pence per kWh. If you do not have a cheap period, use the same figure as Home rate.
The time your tariff’s off-peak period begins. Check your tariff terms for the exact clock time.
The time your off-peak period ends. An overnight window crossing midnight is supported.
