EV Charging Time Calculator
Calculate how long it will take to charge your electric vehicle with our comprehensive calculator. Determine optimal charging times based on battery capacity, charger power, and other specifications.
Step 1: EV Specifications
Understanding Battery Charging
Most EVs charge fastest from 20% to 80% battery capacity. Charging typically slows down significantly above 80% to protect battery health and longevity.
Step 2: Charging Parameters
About Charging Efficiency
Charging efficiency accounts for energy loss during the charging process, typically 5-15% depending on the charger type, cable quality, and ambient temperature. Higher efficiency means less energy loss.

Charging Process Breakdown
Charging Time Formula
Charging Time = (Battery Capacity × (Target% – Current%)) / (Charger Power × Efficiency)
To calculate charging time: Multiply battery capacity by the percentage of charge needed, then divide by the product of charger power and charging efficiency (as a decimal).
