Real charging often slows down above about 80% (especially on DC fast chargers) to protect battery health, so the last stretch can take longer than this simple average-rate estimate suggests.

How to use this tool

  1. 1Enter your EV's battery capacity in kWh.
  2. 2Enter your charger's power in kW.
  3. 3Enter starting and target charge percentages.
  4. 4See the estimated charging time.

Frequently asked questions

Why might real charging take longer than this estimate?+

Charging speed typically slows down above about 80% charge (especially on DC fast chargers) to protect the battery, so the estimate here — based on an average rate — can understate the last stretch.
