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
Mercedes CLA — frequently asked
How long does it take to charge a Mercedes CLA 250+ with EQ Technology?
From 10% to 80% in approximately 28 minutes on a 150 kW DC fast charger. From empty to full in around 12h 46m 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 Mercedes CLA’s maximum charging speed?
The Mercedes CLA 250+ with EQ Technology accepts up to 320 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 Mercedes CLA use a 350 kW ultra-rapid charger?
Yes, but it will draw at most 320 kW. There is no benefit to a 350 kW unit over a 250 kW unit for this car.
How long to charge a Mercedes CLA at home?
On a typical 7.4 kW home wallbox the Mercedes CLA fills from empty in around 12h 46m. Plug in overnight and the charge time stops mattering.
Is it bad to charge the Mercedes CLA 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.
