How we calculate
The formula, in the open
Charging time is energy needed divided by effective power. We model the typical, warm, healthy case so the number is honest, not optimistic. Read the full methodology for the curve assumptions and sources.
Common Questions
Audi Q4 e-tron — frequently asked
How long does it take to charge a Audi Q4 e-tron 45 e-tron?
From 10% to 80% in approximately 25 minutes on a 150 kW DC fast charger. From empty to full in around 11h 34m on a 7.4 kW home wallbox. Times above are for a warm, healthy battery — cold packs and busy charger sites can extend them by 10–20%.
What is the Audi Q4 e-tron’s maximum charging speed?
The Audi Q4 e-tron 45 e-tron accepts up to 175 kW on a DC fast charger and up to 11 kW on AC. Power tapers above 80% state of charge to protect the battery cells.
Can the Audi Q4 e-tron use a 350 kW ultra-rapid charger?
It will work but the car only draws up to 175 kW. A 175 kW or 150 kW charger gives the same speed at lower cost.
How long to charge a Audi Q4 e-tron at home?
On a typical 7.4 kW home wallbox the Audi Q4 e-tron fills from empty in around 11h 34m. Plug in overnight and the charge time stops mattering.
Is it bad to charge the Audi Q4 e-tron to 100%?
For day-to-day driving most manufacturers recommend an 80% ceiling on lithium-ion (NCM/NCA) chemistries, and 100% on LFP. Charge to 100% before a long trip and use the full range that day.
