📐 Formula & Method
EV Driving Range
This is an energy-based estimate using the consumption value you supply.
📋 How to Use
-
1
Enter usable battery capacity.
-
2
Enter expected consumption per 100 km.
-
3
Calculate estimated full-battery range.
-
4
Allow a reserve for weather and route conditions.
What Changes Real-World EV Range?
Speed, temperature, wind, elevation, tyre pressure, payload, heating, and air conditioning all affect consumption. A recent trip average is usually more useful than a laboratory rating for route planning.
🔬 Methodology & Accuracy
Formula: Uses the standard mathematical formula shown in the Formula & Method section above. All computations run client-side in your browser — no data is sent to our servers.
Data sources: Tax bands, contribution limits and regulatory rates are taken from official US (IRS, SSA) and UK (HMRC, gov.uk) publications for the current tax year, and updated when bands change.
Last reviewed: June 2026 · General formula used: EV Driving Range · Accuracy: Results are precise to two decimal places using IEEE-754 double-precision arithmetic. Intended for educational and planning use only.
