EV Charging Time Calculator

Plan AC or DC charging time with a simple linear estimate.

Fast charging often slows above 80% to protect the battery, so real time can be longer than this estimate.

GUIDE

Calculation notes

Estimate charging time from battery size, current and target charge, charger power, and efficiency.

Real results vary by vehicle condition, local taxes, energy prices, and the manufacturer manual.

Can I make maintenance or purchase decisions from this alone?

No. This is a planning reference. For safety and maintenance, follow the manufacturer manual and qualified mechanics.
