Formula used

Stops = round up max(0, trip distance − starting range) ÷ range added by a full refill.

Worked example

A 900 km trip with 400 km starting range and 500 km per refill needs one refuelling stop. A 1,000 km trip with the same ranges needs two.

What the result means

This counts refills, not station locations. Use conservative range and check station availability on the route.
