How to calculate
Estimate EV driving distance while retaining a battery reserve.
Estimated distance above reserve = capacity*(charge-reserve)/consumption; Energy available above reserve = capacity*(charge-reserve)/100
Worked example
Usable battery capacity (kWh): 60; Available charge (%): 80; Reserve charge (%): 10; Expected battery consumption (kWh/100 km): 15.
Estimated distance above reserve: 280 km; Energy available above reserve: 42 kWh.
Assumptions and limits
No. Speed, weather, terrain, battery condition and auxiliary loads affect range. Keep a suitable reserve and use the vehicle’s guidance.
Results are rounded for display; calculations use unrounded values. Read our calculation methodology.
Understanding the result
Estimated distance uses only energy above your chosen reserve. Consumption should reflect expected conditions.
