What Is a Charging Curve?

When using a DC fast charger, your EV doesn’t charge at the same speed the whole time. The charging speed changes as your battery fills up this pattern is called a charging curve.

Key things to know:

Fastest charging happens between 10% and 50%
The battery charges quickest when it's low. Peak speeds don’t usually last long.

Speed drops after 80%
Charging slows down significantly past 80%, so it’s best to unplug and go if you don’t need the full charge.

Your EV controls the speed
The car’s Battery Management System decides how fast to charge to protect the battery - not the charger.

Each EV has a different charging curve
Some cars slow down earlier or charge faster than others.

Cold weather slows charging
Lower temperatures affect battery performance and charging speed.
