12 practical calculators

EV planning tools

Start with a decision, a charging question, or a cost estimate.

01 · EV fit

Would an EV fit your routine?

A quick screen based on daily distance, charging access, long-trip frequency, and climate.

Open tool
02 · Charging

How much range could a session add?

Estimate energy added and approximate range from a charge window and your vehicle's consumption.

Open tool
03 · Ownership

What might annual running costs be?

Turn distance, consumption, electricity price, and public-charging share into a transparent baseline.

Open tool
04 · Road trips

How many charging stops might a trip need?

Estimate the energy and charging time needed for a long drive while keeping a battery reserve.

Open tool
05 · Vehicle costs

Compare EV and petrol running costs

Put purchase prices, energy use, and annual service costs on the same multi-year baseline.

Open tool
06 · Cold weather

Estimate a winter range adjustment

Apply a transparent planning allowance to a reference range for a colder driving scenario.

Open tool
07 · Home charging

Estimate home charging power and range

Convert a voltage, current, and charging window into approximate energy and driving range.

Open tool
08 · Battery health

Estimate capacity and range at a battery health level

Translate a battery state-of-health percentage into an approximate usable capacity and range baseline.

Open tool
09 · Solar charging

Estimate the value of solar EV charging

Estimate how much surplus solar energy could cover vehicle charging and what grid spend it may avoid.

Open tool
10 · Session cost

Estimate the cost of one charging session

Calculate the bill for a chosen state-of-charge change, electricity rate, charging loss, and session fee.

Open tool
11 · Used EV check

Build a used EV inspection scorecard

Record the evidence available for six practical checks and see which items still need follow-up.

Open tool
12 · Electricity tariffs

Compare flat and time-of-use charging rates

Estimate annual EV charging spend at a flat rate and with the off-peak share you could realistically shift.
