Estimate charge sessions
Set current and target charge, battery size, charger power, and efficiency to see energy needed and distance added.
EV charging, planned clearly
Know when your EV will be ready.
EV Charge Calculator turns battery size, state of charge, charger speed, and electricity price into practical estimates for time, cost, range added, and when to start charging.
Compare charger setups
Switch between common Level 1, Level 2, DC fast charging, single-phase, and three-phase presets.
Plan cost and timing

Built for real charging decisions
From overnight charging to road-trip stops.
