Does this calculator measure my battery health?

No. It uses a health percentage you supply or a clearly labelled assumption. It does not diagnose, test or certify the vehicle’s battery.

What if I do not know the battery health?

Choose Unknown and explore an assumed percentage. The result is a scenario, not a measured result for the car. Replace the assumption when you have a suitable battery health result.

Which battery capacity should I enter?

Use the original usable capacity in kWh for the specific vehicle variant, not gross capacity or its current charge percentage. The calculator applies your health percentage to estimate remaining usable energy.

Are charging losses and public charging included?

Simple assumes all charging at home and excludes charging losses. Advanced lets you enter charging efficiency, home and public prices, and the share charged at home. Session, parking and idle fees are excluded.

Is the estimated range guaranteed?

No. The estimate uses your selected charge window and consumption. Weather, speed, terrain and battery temperature can change actual range. Follow the vehicle’s charging guidance.

EV battery health, range & charging calculator

Turn a battery health figure into an everyday driving estimate. Enter usable battery capacity and your driving distance, then explore range, charging costs and time at home.

Explore range and charging costs using a battery health figure. This tool does not test or certify a battery.

Simple assumes 80% to 20% charge, all charging at home, a 7 kW charger and no charging losses. Advanced adds losses, public charging and power limits.

Charging is included once in the ownership total below. Battery health changes range, not consumption automatically. Changing these inputs never changes a listing.

EV batteries and charging guides

How long an EV battery really lasts

What large real-world datasets show about EV battery degradation, how often batteries are actually replaced, what the warranties guarantee, and how to check state of health before you buy a used one.

Charging an electric car at home

What a normal power point delivers, when a wallbox is worth it, what installation involves, and the honest position for renters and apartment dwellers — where a hybrid is often the better answer.

Public EV charging in Australia

How big the network is, what plugs are used here, what really determines fast-charging speed, and an honest account of where the remaining gaps are for long-distance travel.

What an electric car actually costs to run

Charging costs at home, on off-peak and at public fast chargers, against petrol at Australian prices. What the Electric Vehicle Council and the Government actually publish, with the assumptions shown.
