EV Charging Calculator

Take the guesswork out of EV charging! Estimate how long charging will take, when your EV will be ready, and what it could cost. Save your vehicles, chargers, and rates to make planning your next charge easier. EV Charging Calculator uses your battery size, current and target charge levels, and charging setup to estimate your next charge. Use it at home or at a public charger, from a standard wall outlet to AC charging or DC fast charging. PLAN YOUR CHARGE - See how long charging should take and when it should finish. - Choose a future start time and set an optional reminder to plug in. - Need your vehicle ready by a certain time? Work backward to estimate when charging should begin. - Enter your vehicle’s driving efficiency to estimate the range added in miles or kilometers. ESTIMATE YOUR CHARGING COST - Calculate electricity costs using your price per kWh. - Include session fees, charging time rates, parking fees, and idle fees. - Adjust parking billing and idle fee grace periods to match your charging location. - Enter expected idle time to see how staying after charging could affect the total. - Save pricing with your charger presets for quick access to your usual rates. SAVE YOUR SETUPS - Create presets for multiple vehicles and battery sizes. - Set each vehicle’s maximum AC and DC charging power so estimates account for its charging limits. - Save custom chargers for home, work, or other places you charge. - Choose regional charger and voltage presets, or enter custom values in amps or kilowatts. - Adjust charging efficiency and charge tapering to better match your setup.
