Formula used

Hours = energy added ÷ (charger input power × charging efficiency).

Worked example

60 kWh ÷ (7.4 kW × 0.90) = 9.009 hours, approximately 541 minutes.

What the result means

Use realistic sustained input power. Charging taper, battery temperature and vehicle limits can extend the time.
