Why doesn't my car charge as fast as I expected?

  • Updated

There are multiple factors that may impact your charging speed. The Easee Charger supports up to 22kW. To achieve this your charger must be installed with TN (400V) with a minimum of 32A.  Your car must also support these requirements. 

Exceptional Information Circle Info Icon Most cars today only support AC charging up to 11kW. For information regarding your specific car, please contact your car dealership.

There are several factors that may restrict your charging speed, such as:

  • Your electrical grid 
  • Installation (Fuse size/installation cable, 1-phase or 3-phase) 
  • Charging Cable (16A/1-Phase, 32A/1-Phase, 16A/3-Phase, 32A/3-Phase)
  • The onboard charger

 

 Max Charging speed  Current  Phase mode  Voltage
 3,7 kW  16A  1-Phase  230V (IT)
 7,4 kW  32A  1-Phase  230V (IT)
 11 kW  16A  3-Phase  400V (TN)
 22 kW  32A  3-Phase  400V (TN)

Exceptional Information Circle Info Icon You can also check your Power settings in the Easee App, as these settings may have been restricted by your installer. You may also want to look at your car's settings, as these may also limit your charging speed.

In rare cases your charger may derate current, which will lower the charging speed. This safety measure helps ensure your device does not overheat. See What do I do when high temperatures slow down charging? for more information.
