EV charging time and cost calculator

How long does it take to charge, and what does it cost? Compare a power point, a home wall charger and public fast chargers for your car.

Your car and charge

Battery size

Usable capacity, from the maker's specs or the Green Vehicle Guide.
Most EVs are 40–100 kWh.

kWhEnergy use

Energy use

Most EVs use 14–20 kWh per 100 km; more at highway speed.

kWh/100kmCharge from%Charge to

Charge to

Many makers suggest 80% for daily use; check your manual.
Fast charging slows a lot above 80%.

%Car's max AC rate

Car's max AC rate

The onboard charger limit, often 7 or 11 kW.
A 22 kW charger won't go faster than this.

kWCar's max DC rate

Car's max DC rate

Peak fast-charge speed from the specs, often 50–250 kW.
You only get it briefly, on a warm battery.

Prices

Home

From your power bill. Off-peak, EV plans or solar can be much cheaper; free in a Solar Sharer window.

Public AC

Some are free (shopping centres, councils).

c/kWhFast (DC)

Fast (DC)

Usually about 50–80c per kWh. Some networks add per-minute or idle fees.

Results

Adding 36.0 kWh (20% → 80%) gives about 225 km of driving. The same distance in a petrol car costs about $33.75.

Plan a road trip

Estimate only. Includes typical charging losses (about 10% on AC, 5% on DC). Cold or very hot batteries, shared chargers and the car's own charging curve can make it slower.

How it works

AC charging (power points, wall chargers, public AC) is limited by the car's onboard charger, often 7 or 11 kW.
DC fast charging is limited by the car's maximum rate and slows a lot above about 80%.
Time = energy added ÷ charging speed, plus typical losses (about 10% on AC, 5% on DC).

Tips and catches

Most charging happens at home overnight. A 7 kW wall charger refills a typical day's driving in 1–2 hours.
Power point charging is fine for short daily drives. Plug straight into the wall: don't use extension leads or double adapters, and have an electrician check older wiring.
Off-peak and solar. Charging on an EV plan, from rooftop solar or in a free midday window can cut the cost to a fraction of fast charging.
Fast charging costs more (often 2–3 times home power). Some networks charge per minute or add idle fees if you stay plugged in.
Stop at about 80% on fast chargers: the last 20% can take as long as the first 60%.
Cold or hot batteries charge slower. Many EVs can warm the battery when you navigate to a charger.
Three-phase power only helps if your car's onboard charger supports 11 kW or more.
