DC fast charging power is not constant; this gives an approximate time using average power.

Frequently asked questions

Why does EV charging time vary?

Charging power, battery temperature, target percentage, charging curve and vehicle efficiency all affect the total time.

Is this accurate for DC fast charging?

It gives an approximate result using average power. DC charging power often tapers as state of charge rises.
