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.

%

Estimate charge sessions

Set current and target charge, battery size, charger power, and efficiency to see energy needed and distance added.

kW

Compare charger setups

Switch between common Level 1, Level 2, DC fast charging, single-phase, and three-phase presets.

$

Plan cost and timing

Add your price per kWh, choose start later or end by, and set a reminder when it is time to plug in.

Built for real charging decisions

From overnight charging to road-trip stops.

Charging math depends on your car, battery size, target charge, charger, region voltage, and electricity rate. EV Charge Calculator keeps those variables in one focused screen so you can make a quick plan without a spreadsheet.

Vehicle profiles Save battery sizes for multiple EVs.
Regional presets Use US and international voltage options.
Start-by planning Pick a finish time and calculate when charging should begin.
Private by default No account required for the core calculator.
