How this EV charging calculator works

This EV charging calculator estimates how much energy your car can add during a charging session and what that session could cost. Enter your battery size, current battery percentage, target charge limit, charger speed, time available, and local electricity price to get an instant estimate.

It works for home charging, workplace charging, and higher-power public chargers. You can use it to compare slower portable charging with wall chargers or rapid charging, and quickly see whether the time available is enough to reach your target battery level.

Home charging vs public charging

Use lower charging speeds for portable cables and wall chargers, or higher speeds for rapid public charging, to compare how much energy you can realistically add in the time available.

Why charge limits matter

The calculator respects the charge limit you set, so you can model everyday charging sessions that stop at 80% or another target instead of assuming every session goes to 100%.

What the estimate assumes

Results are based on charger power, battery size, time available, and your electricity price. It is a quick practical estimate designed to help compare charging scenarios, not a vehicle-specific prediction.
