EV charging time calculator
How long will your EV take to charge?
Estimate charging time and home charging cost from battery capacity, start and target state of charge, charging power, and charging efficiency.
Charging session
Estimate time and energy
Time ≈ battery energy needed ÷ (charging power × efficiency). Real charging can slow near high state of charge or because of vehicle and temperature limits.
Level 1 vs Level 2
Power is the biggest time lever.
A higher charging power shortens the estimate until the vehicle's onboard charger or battery becomes the limiting factor.
Why reality can differ
Charging power is not always constant.
Battery temperature, state of charge, vehicle limits, voltage, and thermal management can all change charging speed during a session.

What will that charging cost over a month?
Use your miles, efficiency, and electricity price to estimate ongoing home charging cost.
