Electric driving tool

Plan the energy for an EV road trip

Estimate how much energy your route needs, how many charging stops to allow, and what the charging session budget could be.

Enter the route and the vehicle's real-world assumptions. Keep a margin for weather, traffic, elevation, queues and charger availability.

Use usable battery capacity, rather than the advertised gross pack size. The arrival target and extra backup reserve are added together as the minimum end-of-trip state of charge.

The estimate assumes a reasonably even charge across stops. Confirm the car's charging curve, connector, route and live station status before departure.

This is a planning estimate. It excludes route elevation, temperature, wind, traffic, battery conditioning, charger queues, tapering near high state of charge, station pricing rules and detours. It does not provide live station data or a safe route.

How the estimate works

A transparent range and charging estimate

The planner separates energy required to drive from energy that must come from a charger. It protects the arrival target and your extra reserve instead of treating the full battery as available range.

Charging time is an average planning value. Actual time depends on the vehicle's charge curve, the station's delivered power, battery temperature, state of charge and the station's operating conditions.

1. Estimate road energy

Distance is converted to kilometres. The planner multiplies it by the vehicle consumption in kWh per 100 km to estimate the energy needed for the drive.

2. Protect the reserve

Departure energy above the combined arrival target and backup reserve is available before charging. Any shortfall becomes the energy that charging must add to the battery.

3. Estimate stops and cost

Stops use the battery's chargeable window as a guide. Grid energy includes the entered charging loss, then cost is grid energy multiplied by the entered price per kWh.

EV road-trip planner questions

Does this planner find live charging stations?

No. It is intentionally browser-local and has no network lookup. Use the vehicle maker, the charging operator and a current route planner to confirm compatible stations, opening status, payment and a backup stop.

What does the extra backup reserve mean?

It is an additional percentage of usable battery capacity kept above the arrival target. For example, a 15% arrival target and 5% backup reserve make 20% the minimum planned end-of-trip state of charge.

Why can the actual charging time be longer?

The estimate uses average power. A vehicle may accept less power as the battery fills, and temperature, battery conditioning, queues, connector limits and the station's operating state can add time.

What should I verify before I leave?

Check the vehicle's usable capacity and consumption assumptions, connector compatibility, the route's current charging options, payment method, opening arrangements, weather and a safe backup plan. Keep the arrival and backup reserve rather than planning to reach zero.
