EV Charging Stop Buffer Calculator
Usable trip range is smaller than the dashboard range when you reserve battery at each stop and expect cold, heat, wind, or highway-speed losses. Calculate the usable energy window first, then divide trip distance by adjusted range. Charger spacing and reliability still need to be checked on a current route map.
Planning estimate only. Check measurements and real-world constraints before buying materials or making a commitment.

Worked example
Use this example to check the calculator by hand before relying on a result.
Assumptions behind the result
- • Rated range is known.
- • Range loss is entered by the user.
- • Each stop reaches the same departure charge.
- • Arrival reserve is held on every leg.
- • Charger availability is checked separately.
Mistakes that change the answer
- • Using full rated range between chargers.
- • Subtracting 20 percentage points instead of 20% range loss.
- • Ignoring the longest charger gap on the route.
