Estimate charging time, trip energy, and range — mobile-friendly single-file tool.

Enter your vehicle and charger details or choose a preset. Results include charging time (accounting for efficiency), trip energy required, and estimated range.

Total pack capacity (e.g., 40, 60, 80, 100 kWh).
Manufacturers reserve 5-10% buffer for battery health. Default: 95%.
How far you plan to drive.
Results Formulas used: time = ΔkWh / (kW × η) · trip kWh = (km/100) × kWh/100km
